使用媒体播放器暂停并启动更新TextViews（与搜索栏结合使用）

我设法在拖动或触摸搜索栏时更改文本 . 问题是在单击暂停和播放按钮时更新文本视图 .

这是我到目前为止所取得的成果，并相应地更新了文本视图

private void primarySeekBarProgressUpdater（）{

if(mediaPlayer !=null){
        seekBarProgress.setProgress((int) (((float) mediaPlayer.getCurrentPosition() / mediaFileLengthInMilliseconds) * 100)); // This math construction give a percentage of "was playing"/"song length"
        totalDuration = mediaPlayer.getDuration();
        currentDuration = mediaPlayer.getCurrentPosition();
        statusDuration = totalDuration - currentDuration;
    }

    if(currentDuration > 1000){

        btnPause.setVisibility(View.VISIBLE);
        //mMaterialProgressBar.setVisibility(View.GONE);
        // Displaying Total Duration time
        TotalDurationLabel.setText(""+utils.milliSecondsToTimer(statusDuration));
        // Displaying time completed playing
        CurrentDurationLabel.setText(""+utils.milliSecondsToTimer(currentDuration));
    }


    if (mediaPlayer.isPlaying() && mediaPlayer !=null) {
        notification = new Runnable() {
            public void run() {

                primarySeekBarProgressUpdater();
            }

        };

        handler.postDelayed(notification, 1000);
    }
}

问题在这里 . 单击放置在framelayout内的两个按钮的事件

btnPause.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            if (isAvailable()) {
                // check if we are streaming
                if (mediaPlayer.isPlaying() && mediaPlayer != null) {
                    mediaPlayer.pause();

                    // Changing button image to play button
                    btnPause.setImageResource(R.drawable.play_b);
                    btnPause.setVisibility(View.VISIBLE);
                    btnPlay.setVisibility(View.GONE);
                    seekBarProgress.setVisibility(View.VISIBLE);

                    Log.d(TAG, "Paused but won't update text views");

                    // }
                } else {
                    // Resume song
                    if (mediaPlayer != null) {
                        mediaPlayer.start();
                        // Changing button image to pause button
                        btnPause.setImageResource(R.drawable.pause_b);
                        btnPause.setVisibility(View.VISIBLE);
                        btnPlay.setVisibility(View.INVISIBLE);
                        seekBarProgress.setVisibility(View.VISIBLE);
                        handler.removeCallbacks(notification);
                        Log.d(TAG, "Check here for playback please");
                        primarySeekBarProgressUpdater();
                    }
                }
            } else {
                showMessage("Please enable internet and data to listen music");
            }


        }
    });

我删除了runnable的回调并启动了一个新线程 . 新线程不会像我之前获得的那样更新文本视图
