创建一个JAVA类继承Dialog

package com.example.updataprocess;

import android.app.Dialog;
import android.content.Context;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;

public class SelectDialog  extends Dialog {
    private Context mContext;
    private View view;

    public SelectDialog(Context context, int theme) {
        super(context, theme);
        mContext = context;
    }

    public SelectDialog(Context context) {
        super(context);
        mContext = context;
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //setContentView(R.layout.progress);
        //与刚才创建的Xml文件结合
        view = LayoutInflater.from(mContext).inflate(R.layout.progress,null,false);
        setContentView(view);
    }

    public View aVoid(){
        return view;
    }


}

创建一个drawable文件设置弹框的样式,背景色,填充色,边框线,圆角等

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <!-- rectangle表示为矩形 -->

    <!-- 填充的颜色 -->
    <solid android:color="#fff" />

    <!-- 边框的颜色和粗细 -->
    <stroke
        android:width="1dp"
        android:color="#fff"
        />

    <!-- android:radius 圆角的半径 -->
    <corners
        android:radius="20dp"
            android:topLeftRadius="20dp"
            android:topRightRadius="20dp"
            android:bottomRightRadius="20dp"
            android:bottomLeftRadius="20dp"
            />

</shape>

实际应用

private void showDownloadDialog(){
        //调用继承Dialog的SelectDialog
        final SelectDialog selectDialog = new SelectDialog(mContext,R.style.my_dialog);
        selectDialog.show();
//因为需要在其他方法中关闭弹框,将selectDialog赋值给全局变量downloadDialog
        downloadDialog=selectDialog;

//调用圆角布局,没有这句,圆角外会遗留三角形白色区域
selectDialog.getWindow().setBackgroundDrawableResource(R.drawable.dialogradius);
//配置对话框
        View v = selectDialog.aVoid();
        mProgress = v.findViewById(R.id.progress01);//进度条
        mProgress.setIndeterminate(false);
        mTitle=v.findViewById(R.id.title);//Title
        mMessage=v.findViewById(R.id.message);//message
        mUpdataName=v.findViewById(R.id.filename);//进度信息,这里是文件名
        mNum=v.findViewById(R.id.num);//进度,这里是几分之几
        mCancel=v.findViewById(R.id.Cancel);//取消按钮
        mMidText=v.findViewById(R.id.midText);//文件名和几分之几中间的文字,理论上不会变化,为了设置字体,调用一下
        
  //设置点击事件
        mCancel.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                    selectDialog.dismiss();//关闭窗口
                    interceptFlag = true;//停止下载用
            }
        });
//设置外部字体
        mTitle.setTypeface(tf);
        mUpdataName.setTypeface(tf);
        mCancel.setTypeface(tf);
        mNum.setTypeface(tf);
        mMessage.setTypeface(tf);
        mMidText.setTypeface(tf);
    }

为了设置外部字体需要先创建assets文件夹,再创建fonts文件夹,将外部字体复制进去,然后输入代码

public UpdateManager(Context context) {
        this.mContext = context;

        mgr=mContext.getAssets();
        tf = Typeface.createFromAsset(mgr,"fonts/fzktjt.ttf");
    }

创建handle接受信息更新

private Handler mHandler = new Handler(){
        public void handleMessage(Message msg) {
            switch (msg.what) {
                case 1:
                    mProgress.setProgress(progress);//更新进度条
                    break;
                case 2:
//                    showDownloadOverDialog();
                    System.out.println("下载完成");
                    break;
                case 3:
                    mUpdataName.setText(updataFileName);//更新文件名
                    mNum.setText(updataNum);//更新几分之几
                    break;
                case 4:
                    showDownloadfileDialog();//下载失败弹框
                default:
                    break;
            }
        }
    };

下载方法,我这里是接受后台传来的JSON数组,每个JSON字符串中包含版本包名,版本信息,下载路径等信息

//下载文件并解压
        public boolean downloadApk(JSONArray urllist) {
        final JSONArray data=urllist;
        final FileOperation fileOperation=new FileOperation();
        final JSONArray versionList=new JSONArray();
        //比对包名和版本信息,包名为Key,版本号为value
            final HashMap<String,Integer> versionInfoMap = new  HashMap<String,Integer>();
        
            //设置进度条最大值
            mProgress.setMax(100);
            //创建下载线程,我发现不用线程进度条貌似无法更新
            new Thread(new Runnable() {
                @Override
                public void run() {
                    //循环
            for (int i=0;i<data.length();i++) {
                JSONObject pg =new JSONObject();
                try {
                    String title=data.getJSONObject(i).getString("resPackageNm");
                    Integer version=data.getJSONObject(i).getInt("publishVer");
                    pg.put("resPackageNm",title);
                    pg.put("publishVer",version);
                    //设置下载文件的包名为key
                     if (versionInfoMap.containsKey(title)) {
                         Integer versionInt = versionInfoMap.get(title);
                        //判断版本号是否最大
                         if (versionInt < version) {
                             versionInfoMap.put(title, version);
                         }
                     }else {
                         versionInfoMap.put(title,version);
                     }

                    URL url = new URL(data.getJSONObject(i).getString("path"));
                    HttpURLConnection conn = (HttpURLConnection) url.openConnection();
                    conn.connect();
                    
                    InputStream is = conn.getInputStream();
                    File file = new File(savePath);
                    if (!file.exists()) {
                        file.mkdirs();
                    }
                    String apkFile = saveFileName;

                    File ApkFile = new File(apkFile);
                    FileOutputStream fos = new FileOutputStream(ApkFile);
                    //文件数量进度,这里有4个文件
                    int length=data.length();
                    //计算文件大小,这里弃用
//                    int length = conn.getContentLength()-1;
                    int count = i+1;//正在更新第几个文件
                    progress =(int)(((float)count / length) * 100);//计算出进度,这里会以25%进度更新
                    //进度条显示包名
                    updataFileName=title;
                    //进度条显示
                    updataNum=i+1+"/"+data.length();
                    //这是在干嘛,我也不知道,抄的
                    byte buf[] = new byte[1024];
