Android实现简单画中画功能
Android 8.0推出了PictureInPicture(画中画功能),目前只有在8.0以上的系统上支持。对比IOS,IOS的Picture in Picture 模式是苹果公司在 iOS 9 中加入的一项多任务功能。下面先看一下效果:
相信不少人在平时使用ios手机的app时,已经体验过了,很高兴谷歌也推出了这项功能。
使用画中画模式注意点:
1.要使用画中画模式的Activity需要在清单文件中添加属性:
android:configChanges="screenSize|smallestScreenSize|screenLayout|orientation" android:supportsPictureInPicture="true"
2.需要使用PictureInPictureParams类:
PictureInPictureParams.Builder mPictureInPictureParamsBuilder = new PictureInPictureParams.Builder();
3.添加待决定的意图
ArrayList<RemoteAction> actions = new ArrayList<>(); final PendingIntent intent = PendingIntent.getBroadcast( MainActivity.this, requestCode, new Intent(ACTION_MEDIA_CONTROL).putExtra(EXTRA_CONTROL_TYPE, controlType), 0); actions.add(new RemoteAction(icon, title, title, intent)); mPictureInPictureParamsBuilder.setActions(actions);
4.使用广播接收各种意图
private BroadcastReceiver mReceiver; mReceiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { if (intent == null || !ACTION_MEDIA_CONTROL.equals(intent.getAction())) { return; } // This is where we are called back from Picture-in-Picture action items. //这就是我们从画中画模式的操作回调的地方 final int controlType = intent.getIntExtra(EXTRA_CONTROL_TYPE, 0); switch (controlType) { case CONTROL_TYPE_PLAY: mMovieView.play(); break; case CONTROL_TYPE_PAUSE: mMovieView.pause(); break; } } }; registerReceiver(mReceiver, new IntentFilter(ACTION_MEDIA_CONTROL));
5.配合自定义的MediaPlayer使用:
private MovieView mMovieView; //各种操作 mMovieView.showControls(); mMovieView.pause(); mMovieView.play(); mMovieView.hideControls(); mMovieView.setAdjustViewBounds(false);
通过广播接收者接收各种操作意图,对应其操作
