Question

我需要一个按钮，按下时会启动，再次按下时会停止。否则我有重叠的声音。你们有人可以帮我解决这个问题吗？下面是我目前所拥有的，当再次点击时无法停止按钮，所以当前正在播放并在声音完成时停止，导致声音重叠。在按下另一个按钮时让一个人停下来也是理想的，但我不知道如何轻松地将其合并。

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_boardone);

    Button one = (Button) findViewById(R.id.button1);
    one.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            MediaPlayer mp = MediaPlayer.create(BoardoneActivity.this, R.raw.mouse_laughter);  
            mp.start();

        }
    });

    Button two = (Button) findViewById(R.id.button2);
    two.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            MediaPlayer mp = MediaPlayer.create(BoardoneActivity.this, R.raw.evil_laugh);  
            mp.start();
        }
    });

不要使用Media Player的两个对象。以下是我项目中的方法片段。如果有任何错误让我知道。

private MediaPlayerManager mRecordingPlayer = null;



        private void initAudioPlayer(){
        if(mRecordingPlayer == null){
            mRecordingPlayer = new MediaPlayerManager();

        }
    }


        private void playMusic(int position){
        initAudioPlayer();
        mRecordingPlayer.resetPlayer();
        mRecordingPlayer.setupPlayback("your reasource");
        mRecordingPlayer.startPlaying();
    }

       private void stopPlaying(){
        initAudioPlayer();
        if(mRecordingPlayer.isPlaying()){
            mRecordingPlayer.pausePlaying();

        }

    }


    @Override
    public void onPause() {
        clearAudioPlayer();
        super.onPause();
    }


    private void clearAudioPlayer(){
        if(mRecordingPlayer != null ){
            mRecordingPlayer.resetPlayer();
        }
    }


   @Override
    public void onClick(View view) {

        boolean on = ((ToggleButton) view).isChecked();
            if(on){
                playMusic("play music");
                ((ToggleButton) view).setChecked(true);
            }else{
                stopPlaying();
            }

    }

使用以下代码尝试。

mPlayPause.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View arg0) {
                if (mp.isPlaying()) {
                    if (mp != null) {
                        mp.pause();
                        mPlayPause.setText("Play");
                    }
                } else {
                    if (mp != null) {
                        mp.start();
                        mPlayPause.setText("Pause");
                    }
                }
            }
        });

启动后使声音按钮停止
