1、悬浮窗不能在当前app中展示
使用activity中的moveTaskToBack(true),获得的悬浮窗效果。
要修改AndroidManifest.xml中
对应的VideoChatViewActivity的模式一定不要用singleTop,修改成singleInstance
如果用singleTop,会认为当前activity就是root,不能获得想要的结果。
一定要修改成这样
2、悬浮窗开发
a、语音通话
浮窗显示一张图片
b、视频通话
浮窗需要显示对方的视频
上代码

2、activity
private void startVideoService() {

//最小化Activity
moveTaskToBack(true);
//Constents.mVideoViewLayout = mVideoViewLayout;
//开启服务显示悬浮框
Intent floatVideoIntent = new Intent(this, FloatVideoWindowService.class);
floatVideoIntent.putExtra("userId", getUserId());
mServiceBound = bindService(floatVideoIntent, mVideoCallServiceConnection, Context.BIND_AUTO_CREATE);
LogUtil.i("startVideoService end");
}
/**
* 定义服务绑定的回调 开启视频通话服务连接onLocalAudioMuteClicked
*/
private ServiceConnection mVideoCallServiceConnection = new ServiceConnection() {
@Override
public void onServiceConnected(ComponentName name, IBinder iBinder) {
// 获取服务的操作对象
floatVideoWindowService = ((FloatVideoWindowService.MyBinder) iBinder).getService();
LogUtil.i("floatVideoWindowService init");
if (floatVideoWindowService != null){
LogUtil.i("floatVideoWindowService init1");
floatVideoWindowService.addIntoSmallSizePreviewLayout(mRemoteVideo);
LogUtil.i("floatVideoWindowService init2");
}
LogUtil.i("floatVideoWindowService init end");
}
@Override
public void onServiceDisconnected(ComponentName name) {
floatVideoWindowService = null;
}
};
@Override
protected void onRestart() {
super.onRestart();
LogUtil.i("floatVideoWindowService onRestart start");
//从悬浮窗进来后重新设置画布(判断是不是接通了)
if (mServiceBound) {
/*//延迟重新加载远端和本地的视频画布
mHandler.postDelayed(new Runnable() {
@Override
public void run() {
}
}, 800);*/
if (mServiceBound && floatVideoWindowService != null){
floatVideoWindowService = null;
unbindService(mVideoCallServiceConnection);
mServiceBound = false;
}
reInitView();
}
LogUtil.i("floatVideoWindowService onRestart end");
}
3、布局文件
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="right">
<FrameLayout
android:layout_width="80dp"
android:layout_height="110dp"
android:background="@color/black_1f2d3d">
<LinearLayout
android:id="@+id/small_size_preview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/transparent"
android:orientation="vertical" />
</FrameLayout>
</LinearLayout>
4、授权,老版本不需要,新版本则需要授权
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
requestAlertWindowPermission();
}
}
@RequiresApi(api = Build.VERSION_CODES.M)
private void requestAlertWindowPermission() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && !Settings.canDrawOverlays(this)) {
Intent intent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION,
Uri.parse("package:" + getPackageName()));
startActivityForResult(intent, 0);
}
}
