android - 如何在配置更改时处于暂停模式时显示android媒体播放器的前一帧

Question

现在我正在使用 android 媒体播放器。因此，当用户将屏幕从纵向旋转到横向，反之亦然时，媒体播放器出现问题。

用户在某个帧以纵向模式暂停视频，因此当用户旋转屏幕时，我想在暂停的地方显示相同的屏幕。在这种情况下，我可以保存玩家之前的位置并向后退，但在这里我看到的是黑屏，而不是上一帧。

代码:1

//Here i am saving previous position of mediplayer
 protected void onSaveInstanceState(Bundle outState) {

        outState.putLong(KEY_IS_MAIN_VIDEO_CURRENT_POSITION, mMainVideoMediaPlayer.getCurrentPosition());

        super.onSaveInstanceState(outState);
    }

2.获取之前的值

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.videoplay_new_layout);

        if (savedInstanceState != null) {
            mIsConfigChanged = true;           


            mMainVideoPreviousPosition = savedInstanceState.getLong(KEY_IS_MAIN_VIDEO_CURRENT_POSITION);


        }

3.准备调用时将保存的先前值设置回播放器

mMainVideoMediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
            @Override
            public void onPrepared(MediaPlayer mp) {

                mMainVideoMediaPlayer.start();
//Setting previous value::::

mMainVideoMediaPlayer.seekTo((int) mMainVideoPreviousPosition);

//Making player pause because mediaplayer player previous state is paused in potrait mode:::

mMainVideoMediaPlayer.pause();


}
});

Answer 1

如果您尝试过评论部分，请尝试这个并告诉我。

mMainVideoMediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
        @Override
        public void onPrepared(MediaPlayer mp) {

            mMainVideoMediaPlayer.start();


mMainVideoMediaPlayer.seekTo((int) mMainVideoPreviousPosition);

//Making player pause because mediaplayer player previous state is paused in potrait mode:::

mMainVideoMediaPlayer.pause();

//Try this code below like hack for now.
//---------------
<playButton>.pefromClick(); //It will start playing 
<pauseButton>.perfromClick(); //immediately pause it.
//------------------


}
});
