MediaPlayer跳到最后一个seekTo（）位置

Question

private void updateProgress() {
    mListenerThread = new Thread(new Runnable() {
        @Override
        public void run() {
            while (isRunning) {
                int position = mMediaPlayer.getCurrentPosition();
                mProgressListener.onProgress(position);
                try {
                    Thread.sleep(500);
                } catch (InterruptedException e) {
                    mMediaPlayer.seekTo(0);
                    e.printStackTrace();
                }
            }
        }
    });
    mListenerThread.start();
}

您可以保存已设置的位置，并检查当前位置是否是设置的位置，如果是，则将进度设置为零，这将阻止在OnCompletionListener上发生跳转

定义变量

int lastSeek = -1;

当搜索时，将其设置到已经搜索到的位置

void seekTo(int position) {
 //do the seeking here
 lastSeek = position;
}

private void updateProgress() {
    mListenerThread = new Thread(new Runnable() {
        @Override
        public void run() {
            while (isRunning) {
                int position = mMediaPlayer.getCurrentPosition();
                mProgressListener.onProgress(position == lastSeek ? 0 : position);
                try {
                    Thread.sleep(500);
                } catch (InterruptedException e) {
                    mMediaPlayer.seekTo(0);
                    e.printStackTrace();
                }
            }
        }
    });
    mListenerThread.start();
}

MediaPlayer.OnCompletionListener completionListener
                      = new MediaPlayer.OnCompletionListener(){    
    @Override
    public void onCompletion(MediaPlayer arg0) {
     lastSeek = -1;
     //set actual position to zero and update the bar
   }
};
