一. 简介:
    JZVedioPlayer 是目前发现的集成和使用起来最简单,也是稳定度很高的一个库JZVedioPlayer 封装了 UI 层和播放器层,让我们可以简简单单的一键集成.二. 集成以及使用:
compile 'cn.jzvd:jiaozivideoplayer:6.2.12' 或 jiaozivideoplayer.jar依赖库(不推荐)
JiaoZiVideoPlayer主要功能使用:可以完全自定义UI和任何功能
多种视频适配屏幕的方式,可铺满全屏,可以全屏剪裁
完美检测列表滑动
可以加载,暂停,播放和其他正常状态进入全屏并退出全屏
切换播放引擎,支持的视频格式和协议的一行代码取决于播放引擎,如: android.media.MediaPlayer,IJKplayer,ExoPlayer。
全屏适用于多种嵌套模式,如ListView,ViewPager和ListView,ViewPager和Fragment
提供全屏和小窗口选项
Home键退出界面暂停播放,返回界面继续播放
WebView嵌套本地视频控件
全屏后手势修改进度和音量
VideoCache在演示中 
三. 接下来我们从三步来实现简单视频播放
1) 首先设置你的布局文件     <cn.jzvd.demo.CustomView.MyJzvdStd
                android:id="@+id/jz_video"
                android:layout_width="match_parent"
                android:layout_height="300dp" />
2)  ActivityMain中设置视频初始化操作   @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        //初始化控件
        myJzvdStd = findViewById(R.id.jz_video);
        /**
         * 参数说明
         * 视频播放地址
         * 设置视频标题
         */
        myJzvdStd.setUp("http://jzvd.nathen.cn/342a5f7ef6124a4a8faf00e738b8bee4/cf6d9db0bd4d41f59d09ea0a81e918fd-5287d2089db37e62345123a1be272f8b.mp4"
                , "饺子快长大", JzvdStd.SCREEN_WINDOW_NORMAL);
        //设置视频封面
        Glide.with(this).load("http://jzvd-pic.nathen.cn/jzvd-pic/1bb2ebbe-140d-4e2e-abd2-9e7e564f71ac.png").into(myJzvdStd.thumbImageView);
        Jzvd.setJzUserAction(new MyUserActionStd());

    }

    @Override
    protected void onPause() {
        super.onPause();
        Jzvd.releaseAllVideos();
    }

    @Override
    public void onBackPressed() {
        if (Jzvd.backPress()) {
            return;
        }
        super.onBackPressed();
    }


    /**
     * 这只是给埋点统计用户数据用的,不能写和播放相关的逻辑,监听事件请参考MyJzvdStd,复写函数取得相应事件
     */
    class MyUserActionStd implements JZUserActionStd {

        @Override
        public void onEvent(int type, Object url, int screen, Object... objects) {
            switch (type) {
            //继承JzvdStd之后,可以通过父类的mCurrentState,取得当前的播放状态。
            //CURRENT_STATE_IDLE 未知状态,指控件被new出来之后什么都没做
            //CURRENT_STATE_NORMAL 普通状态
            //CURRENT_STATE_PREPARING 视频准备状态
            //CURRENT_STATE_PREPARING_CHANGING_URL 播放中切换url的准备状态
            //CURRENT_STATE_PLAYING 播放中状态
            //CURRENT_STATE_PAUSE 暂停状态
            //CURRENT_STATE_AUTO_COMPLETE 自动播放完成状态
            //CURRENT_STATE_ERROR 错误状态

                case JZUserAction.ON_CLICK_START_ICON:
                    Log.i("USER_EVENT", "ON_CLICK_START_ICON" + " title is : " + (objects.length == 0 ? "" : objects[0]) + " url is : " + url + " screen is : " + screen);
                    break;
                case JZUserAction.ON_CLICK_START_ERROR:
                    Log.i("USER_EVENT", "ON_CLICK_START_ERROR" + " title is : " + (objects.length == 0 ? "" : objects[0]) + " url is : " + url + " screen is : " + screen);
                    break;
                case JZUserAction.ON_CLICK_START_AUTO_COMPLETE:
                    Log.i("USER_EVENT", "ON_CLICK_START_AUTO_COMPLETE" + " title is : " + (objects.length == 0 ? "" : objects[0]) + " url is : " + url + " screen is : " + screen);
                    break;
                case JZUserAction.ON_CLICK_PAUSE:
                    Log.i("USER_EVENT", "ON_CLICK_PAUSE" + " title is : " + (objects.length == 0 ? "" : objects[0]) + " url is : " + url + " screen is : " + screen);
                    break;

                    Log.i("USER_EVENT", "ON_CLICK_RESUME" + " title is : " + (objects.length == 0 ? "" : objects[0]) + " url is : " + url + " screen is : " + screen);
                    break;
                case JZUserAction.ON_SEEK_POSITION:
                    Log.i("USER_EVENT", "ON_SEEK_POSITION" + " title is : " + (objects.length == 0 ? "" : objects[0]) + " url is : " + url + " screen is : " + screen);
                    break;
                case JZUserAction.ON_AUTO_COMPLETE:
                    Log.i("USER_EVENT", "ON_AUTO_COMPLETE" + " title is : " + (objects.length == 0 ? "" : objects[0]) + " url is : " + url + " screen is : " + screen);
                    break;
                case JZUserAction.ON_ENTER_FULLSCREEN:
                    Log.i("USER_EVENT", "ON_ENTER_FULLSCREEN" + " title is : " + (objects.length == 0 ? "" : objects[0]) + " url is : " + url + " screen is : " + screen);
                    break;
                case JZUserAction.ON_QUIT_FULLSCREEN:
                    Log.i("USER_EVENT", "ON_QUIT_FULLSCREEN" + " title is : " + (objects.length == 0 ? "" : objects[0]) + " url is : " + url + " screen is : " + screen);
                    break;
                case JZUserAction.ON_ENTER_TINYSCREEN:
                    Log.i("USER_EVENT", "ON_ENTER_TINYSCREEN" + " title is : " + (objects.length == 0 ? "" : objects[0]) + " url is : " + url + " screen is : " + screen);
                    break;
                case JZUserAction.ON_QUIT_TINYSCREEN:
                    Log.i("USER_EVENT", "ON_QUIT_TINYSCREEN" + " title is : " + (objects.length == 0 ? "" : objects[0]) + " url is : " + url + " screen is : " + screen);
                    break;
                case JZUserAction.ON_TOUCH_SCREEN_SEEK_VOLUME:
                    Log.i("USER_EVENT", "ON_TOUCH_SCREEN_SEEK_VOLUME" + " title is : " + (objects.length == 0 ? "" : objects[0]) + " url is : " + url + " screen is : " + screen);
                    break;

                    Log.i("USER_EVENT", "ON_CLICK_BLANK" + " title is : " + (objects.length == 0 ? "" : objects[0]) + " url is : " + url + " screen is : " + screen);
                    break;
                default:
                    Log.i("USER_EVENT", "unknow");
                    break;
            }
        }
    }
 3) 在清单文件中AndroidManifest.xml中添加 "android:configChanges="orientation|screenSize|keyboardHidden"<activity
    android:name=".MainActivity"
    android:configChanges="orientation|screenSize|keyboardHidden"
    android:screenOrientation="portrait" />
四. JiaoZiVideoPlayer 基本使用
  1) 自动播放(两种方法选其一)  myJzvdStd.startButton.performClick();
myJzvdStd.startVideo();

/*
*跳转制定位置播放
*这里只有开始播放时才生效
*/
mJzvdStd.seekToInAdvance = 20000;
//跳转制定位置播放
JZMediaManager.seekTo(30000);
 2) 播放本地下下视频public void getAssertVideoToLocalPath() {
        try {
            InputStream myInput;
            OutputStream myOutput = new FileOutputStream(Environment.getExternalStorageDirectory().getAbsolutePath() + "/DCIM/Camera/local_video.mp4");
            myInput = this.getAssets().open("local_video.mp4");
            byte[] buffer = new byte[1024];
            int length = myInput.read(buffer);
            while (length > 0) {
                myOutput.write(buffer, 0, length);
                length = myInput.read(buffer);
            }

            myOutput.flush();
            myInput.close();
            myOutput.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
myJzvdStd.setUp(Environment.getExternalStorageDirectory().getAbsolutePath() + "/DCIM/Camera/local_video.mp4", "饺子不信",Jzvd.SCREEN_WINDOW_NORMAL, );
 3)  播放assets目录下的视频JZDataSource jzDataSource = null;
        try {
            jzDataSource = new JZDataSource(getAssets().openFd("local_video.mp4"));
            jzDataSource.title = "饺子快长大";
        } catch (IOException e) {
            e.printStackTrace();
        }
        jzvdStd.setUp(jzDataSource, JzvdStd.SCREEN_WINDOW_NORMAL);
        Glide.with(this)
                .load("http://jzvd-pic.nathen.cn/jzvd-pic/1bb2ebbe-140d-4e2e-abd2-9e7e564f71ac.png")
                .into(jzvdStd.thumbImageView);

        Jzvd.setMediaInterface(new CustomMediaPlayerAssertFolder());
 4) 切换成全屏模式以及小窗口模式        //切换全屏
        JzvdStd.startFullscreen(this, JzvdStd.class, VideoConstant.videoUrlList[6], "视频的标题");
        //设置小窗口模式
        mJzvdStd.startWindowTiny();

 5) 列表Item划出开启小窗播放1.Listview
   listView.setOnScrollListener(new AbsListView.OnScrollListener() {
            @Override
            public void onScrollStateChanged(AbsListView view, int scrollState) { 

            }
            @Override
            public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) {
                Jzvd.onScrollAutoTiny(view, firstVisibleItem, visibleItemCount, totalItemCount);
              // Jzvd.onScrollReleaseAllVideos(view, firstVisibleItem, visibleItemCount, totalItemCount);  这是不开启列表划出小窗 同时也是画出屏幕释放JZ 划出暂停
            }
        });
2. RecyclerView  划出列表开启小窗
   recyclerView.addOnChildAttachStateChangeListener(new RecyclerView.OnChildAttachStateChangeListener() {
            @Override
            public void onChildViewAttachedToWindow(View view) {
                Jzvd.onChildViewAttachedToWindow(view, R.id.videoplayer);
            }

            @Override
            public void onChildViewDetachedFromWindow(View view) {
                Jzvd.onChildViewDetachedFromWindow(view);
            }
        });
2.1 RecyclerView划出屏幕释放JZ,同时也是不开启列表划出显示小窗
    recyclerView.addOnChildAttachStateChangeListener(new RecyclerView.OnChildAttachStateChangeListener() {
            @Override
            public void onChildViewAttachedToWindow(View view) {

            }

            @Override
            public void onChildViewDetachedFromWindow(View view) {
                Jzvd jzvd = view.findViewById(R.id.videoplayer);
                if (jzvd != null && jzvd.jzDataSource.containsTheUrl(JZMediaManager.getCurrentUrl())) {
                    Jzvd currentJzvd = JzvdMgr.getCurrentJzvd();
                    if (currentJzvd != null && currentJzvd.currentScreen != Jzvd.SCREEN_WINDOW_FULLSCREEN) {
                        Jzvd.releaseAllVideos();
                    }
                }
            }
        });
6) 小屏播放无声音,全屏有声音创建一个类继承JzvdStd并在XML设置
public class JzvdStdVolumeAfterFullscreen extends JzvdStd {
    public JzvdStdVolumeAfterFullscreen(Context context) {
        super(context);
    }

    public JzvdStdVolumeAfterFullscreen(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public void onPrepared() {
        super.onPrepared();
        if (currentScreen == SCREEN_WINDOW_FULLSCREEN) {
            JZMediaManager.instance().jzMediaInterface.setVolume(1f, 1f);
        } else {
            JZMediaManager.instance().jzMediaInterface.setVolume(0f, 0f);
        }
    }

    /**
     * 进入全屏模式的时候关闭静音模式
     */
    @Override
    public void startWindowFullscreen() {
        super.startWindowFullscreen();
        JZMediaManager.instance().jzMediaInterface.setVolume(1f, 1f);
    }

    /**
     * 退出全屏模式的时候开启静音模式
     */
    @Override
    public void playOnThisJzvd() {
        super.playOnThisJzvd();
        JZMediaManager.instance().jzMediaInterface.setVolume(0f, 0f);
    }
}
 7) 全屏状态播放完成,不退出全屏创建一个类继承JzvdStd并在XML设置
public class JzvdStdAutoCompleteAfterFullscreen extends JzvdStd {
    public JzvdStdAutoCompleteAfterFullscreen(Context context) {
        super(context);
    }

    public JzvdStdAutoCompleteAfterFullscreen(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public void startVideo() {
        if (currentScreen == SCREEN_WINDOW_FULLSCREEN) {
            Log.d(TAG, "startVideo [" + this.hashCode() + "] ");
            initTextureView();
            addTextureView();
            AudioManager mAudioManager = (AudioManager) getContext().getSystemService(Context.AUDIO_SERVICE);
            mAudioManager.requestAudioFocus(onAudioFocusChangeListener, AudioManager.STREAM_MUSIC, AudioManager.AUDIOFOCUS_GAIN_TRANSIENT);
            JZUtils.scanForActivity(getContext()).getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

            JZMediaManager.setDataSource(jzDataSource);
            JZMediaManager.instance().positionInList = positionInList;
            onStatePreparing();
        } else {
            super.startVideo();
        }
    }

    @Override
    public void onAutoCompletion() {
        if (currentScreen == SCREEN_WINDOW_FULLSCREEN) {
            onStateAutoComplete();
        } else {
            super.onAutoCompletion();
        }

    }
}
 8) 全屏模式下显示分享按钮复制DEMO下的layout文件在 layout_top 布局下 添加你的分享按钮
public class JzvdStdShowShareButtonAfterFullscreen extends JzvdStd {

    public ImageView shareButton;

    public JzvdStdShowShareButtonAfterFullscreen(Context context) {
        super(context);
    }

    public JzvdStdShowShareButtonAfterFullscreen(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public void init(Context context) {
        super.init(context);
        shareButton = findViewById(R.id.share);
        shareButton.setOnClickListener(this);

    }

    @Override
    public int getLayoutId() {
        return R.layout.layout_standard_with_share_button;
    }

    @Override
    public void onClick(View v) {
        super.onClick(v);
        if (v.getId() == R.id.share) {
            Toast.makeText(getContext(), "Whatever the icon means", Toast.LENGTH_SHORT).show();
        }
    }

    @Override
    public void setUp(JZDataSource jzDataSource, int screen) {
        super.setUp(jzDataSource, screen);
        if (currentScreen == SCREEN_WINDOW_FULLSCREEN) {
            shareButton.setVisibility(View.VISIBLE);
        } else {
            shareButton.setVisibility(View.INVISIBLE);
        }
    }
}

 9) 小屏状态下不显示标题,全屏模式下显示标题public class JzvdStdShowTitleAfterFullscreen extends JzvdStd {
    public JzvdStdShowTitleAfterFullscreen(Context context) {
        super(context);
    }

    public JzvdStdShowTitleAfterFullscreen(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public void setUp(JZDataSource jzDataSource, int screen) {
        super.setUp(jzDataSource, screen);
        if (currentScreen == SCREEN_WINDOW_FULLSCREEN) {
            titleTextView.setVisibility(View.VISIBLE);
        } else {
            titleTextView.setVisibility(View.INVISIBLE);
        }
    }
}
 10) 播放MP3public class JzvdStdMp3 extends JzvdStd {

    public JzvdStdMp3(Context context) {
        super(context);
    }

    public JzvdStdMp3(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public int getLayoutId() {
        return R.layout.jz_layout_standard_mp3;
    }

    @Override
    public void onClick(View v) {
        if (v.getId() == cn.jzvd.R.id.thumb &&
                (currentState == CURRENT_STATE_PLAYING ||
                        currentState == CURRENT_STATE_PAUSE)) {
            onClickUiToggle();
        } else if (v.getId() == R.id.fullscreen) {

        } else {
            super.onClick(v);
        }
    }

    //changeUiTo 真能能修改ui的方法
    @Override
    public void changeUiToNormal() {
        super.changeUiToNormal();
    }

    @Override
    public void changeUiToPreparing() {
        super.changeUiToPreparing();
    }

    @Override
    public void changeUiToPlayingShow() {
        super.changeUiToPlayingShow();
        thumbImageView.setVisibility(View.VISIBLE);

    }

        super.changeUiToComplete();
    }

    @Override
    public void changeUiToError() {
        super.changeUiToError();
    }
}

        jzvdStdMp3 = findViewById(R.id.jz_videoplayer_mp3);
        jzvdStdMp3.setUp(URL, "饺子摇摆", Jzvd.SCREEN_WINDOW_NORMAL);
        Glide.with(this)
                .load(VideoConstant.videoThumbs[0][1])
                .into(jzvdStdMp3.thumbImageView);
 11) 播放完成不显示预览图public class JzvdStdShowTextureViewAfterAutoComplete extends JzvdStd {
    public JzvdStdShowTextureViewAfterAutoComplete(Context context) {
        super(context);
    }

    public JzvdStdShowTextureViewAfterAutoComplete(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public void onAutoCompletion() {
        super.onAutoCompletion();
        thumbImageView.setVisibility(View.GONE);
    }

}
 12) Home键退出界面暂停播放,返回界面继续播放  @Override
    protected void onResume() {
        super.onResume();
        //home back
        JzvdStd.goOnPlayOnResume();
    }

    @Override
    protected void onPause() {
        super.onPause();
   //     Jzvd.clearSavedProgress(this, null);
        //home back
        JzvdStd.goOnPlayOnPause();
    }
 13) 边播边缓存和清晰度切换1. 集成videocache implementation 'com.danikula:videocache:2.7.0',并初始化
public class ApplicationDemo extends Application {

    @Override
    public void onCreate() {
        super.onCreate();
//        LeakCanary.install(this);
    }

    private HttpProxyCacheServer proxy;

    public static HttpProxyCacheServer getProxy(Context context) {
        ApplicationDemo app = (ApplicationDemo) context.getApplicationContext();
        return app.proxy == null ? (app.proxy = app.newProxy()) : app.proxy;
    }

    private HttpProxyCacheServer newProxy() {
        return new HttpProxyCacheServer(this);
    }
}
2.引用
        LinkedHashMap map = new LinkedHashMap();

        String proxyUrl = ApplicationDemo.getProxy(this).getProxyUrl(VideoConstant.videoUrls[0][9]);

        map.put("高清", proxyUrl);
        map.put("标清", VideoConstant.videoUrls[0][6]);
        map.put("普清", VideoConstant.videoUrlList[0]);
        JZDataSource jzDataSource = new JZDataSource(map, "饺子不信");
        jzDataSource.looping = true;
        jzDataSource.currentUrlIndex = 2;
        jzDataSource.headerMap.put("key", "value");//header
        mJzvdStd.setUp(jzDataSource
                , JzvdStd.SCREEN_WINDOW_NORMAL);
        Glide.with(this).load(VideoConstant.videoThumbList[0]).into(mJzvdStd.thumbImageView);
 14) 重复播放创建一个类集成JzvdStd并在XML设置
public class JZVideoPlayerStandardLoopVideo extends JzvdStd{
    public JZVideoPlayerStandardLoopVideo (Context context) {
        super(context);
    }

    public JZVideoPlayerStandardLoopVideo (Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public void onAutoCompletion() {
        super.onAutoCompletion();
        startVideo();
    }
}
还有一种方法就是上面清晰度切换loop循环标志
 15) 重力感应自动进入全屏    SensorManager mSensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);
    Jzvd.JZAutoFullscreenListener mSensorEventListener = new Jzvd.JZAutoFullscreenListener();
    @Override
    protected void onResume() {
        super.onResume();
        Sensor accelerometerSensor = mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
        mSensorManager.registerListener(mSensorEventListener, accelerometerSensor, SensorManager.SENSOR_DELAY_NORMAL);
    }

    @Override
    protected void onPause() {
        super.onPause();
        mSensorManager.unregisterListener(mSensorEventListener);
   }

 16) 重力感应Jzvd.FULLSCREEN_ORIENTATION=ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE;
Jzvd.NORMAL_ORIENTATION = ActivityInfo.SCREEN_ORIENTATION_PORTRAIT;
两个变量控制全屏前后的屏幕方向
 17) 不保存播放进度Jzvd.SAVE_PROGRESS = false;
 18) 取消播放时在非WIFIDialog提示Jzvd.WIFI_TIP_DIALOG_SHOWED=true;
19) 清除某个URL进度 Jzvd.clearSavedProgress(this, "url");
