Android MediaPlayer SeekTo function workaround
提问by Natarajan Raman
I am creating a very simple media player app. I would like to resume the song from the SeekTo position that I have captured using getCurrentPosition. However seekTo does not start from the position I have captured but from the beginning.
我正在创建一个非常简单的媒体播放器应用程序。我想从使用 getCurrentPosition 捕获的 SeekTo 位置恢复歌曲。然而，seekTo 不是从我捕获的位置开始，而是从头开始。
Code to capture current position, pause and change button text to Click to resume
用于捕获当前位置、暂停和更改按钮文本以单击以恢复的代码
int media_length = mediaplayer.getCurrentPosition();
Toast.makeText(this,"media length is"+media_length, Toast.LENGTH_LONG).show();
mbutton.setText("Click to Resume");
mediaplayer.pause();
Code to seekTo captured position, start and change button text to Click to Pause
代码来寻找捕获的位置，开始并将按钮文本更改为单击以暂停
mediaplayer.seekTo(media_length);
mediaplayer.start();
mbutton.setText("Click to Pause");
A couple of posts are there already related to it but they seem to claim a bug in Android. Ref: MediaPlayer seekTo doesn't workand is there any workaround for this? appreciate any help.
已经有几个帖子与之相关，但他们似乎声称 Android 中存在错误。参考：MediaPlayer seekTo 不起作用，是否有任何解决方法？感谢任何帮助。

You can try below code. It is working for me...
你可以试试下面的代码。它对我有用...
public void forwardSong() {
if (mPlayer != null) {
int currentPosition = mPlayer.getCurrentPosition();
if (currentPosition + seekForwardTime <= mPlayer.getDuration()) {
mPlayer.seekTo(currentPosition + seekForwardTime);
} else {
mPlayer.seekTo(mPlayer.getDuration());
}
}
}
You can pause mediaplayer before this and just call start method after this method.
您可以在此之前暂停媒体播放器，并在此方法之后调用 start 方法。

Try to use the callback MediaPlayer.OnSeekCompleteListener.
尝试使用回调 MediaPlayer.OnSeekCompleteListener。
Important : In this sample, i've added SystemClock.sleep(200)because onSeekComplete(MediaPlayer arg0)is called too soon by the player BEFORE seekTo is really completed.
重要提示：在此示例中，我添加了SystemClock.sleep(200)因为onSeekComplete(MediaPlayer arg0)在seekTo 真正完成之前玩家太快地调用了它。
mMediaPlayer.setOnSeekCompleteListener(new MediaPlayer.OnSeekCompleteListener() {
@Override
public void onSeekComplete(MediaPlayer arg0) {
Log.d(TAG, "onSeekComplete() current pos : " + arg0.getCurrentPosition());
SystemClock.sleep(200);
mMediaPlayer.start();
}
});
try {
mMediaPlayer.seekTo(mCurrentPos);
} catch (IllegalStateException e){
Log.d(TAG, e.getLocalizedMessage(), e);
}

Try this , it works
试试这个，它有效
videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mp) {
mp.start();
mp.setOnSeekCompleteListener(new MediaPlayer.OnSeekCompleteListener() {
@Override
public void onSeekComplete(MediaPlayer mp) {
mp.start();
}
});
}
});
