android-连续播放声音onTouch()

我想通过onTouch连续播放枪声.我这样做是为了自动发出枪声.所以我有声音循环延迟的问题.不会产生真正的自动枪声效果.我的主要观点是,声音一遍又一遍地播放应该没有延迟.
我的代码是.

public boolean onTouch(View v, MotionEvent event) {
    // TODO Auto-generated method stub

    if (event.getAction() == MotionEvent.ACTION_DOWN) {
        mediaPlayer = MediaPlayer.create(RipleFire.this,
                sounds[position]);
        // if (mediaPlayer != null && mediaPlayer.isPlaying()) {
        // mediaPlayer.stop();
        // }
        try {
            mediaPlayer.prepare();
        } catch (IllegalStateException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        imgflag.setImageResource(pistols[position]);

        imgflag.setImageResource(pistolsAnimations[position]);
        mediaPlayer.start();
        mediaPlayer.setLooping(true);

    } else if (event.getAction() == MotionEvent.ACTION_UP) {
        mediaPlayer.stop();
        mediaPlayer.reset();
        mediaPlayer.release();
        imgflag.setImageResource(pistols[position]);
    }

    return true;
}

解决方法:

方法1
只需通过启动声音即可覆盖触摸方式.

    @Override
            public boolean onTouch(View v, MotionEvent event) {
                switch (event.getAction()) {
                case MotionEvent.ACTION_DOWN:
                    mPlayer.setLooping(true);
                    mPlayer.start();
                    break;
                case MotionEvent.ACTION_UP:
                    mPlayer.pause();
                    break;
                }
                return true;
            }
    //or
    public boolean onTouch(View v, MotionEvent me) {
    switch(me.getAction()) {
        case MotionEvent.ACTION_DOWN:
            if(!mPlayer.isPlaying()) mPlayer.start();
            break;
        case MotionEvent.ACTION_UP:
            if(mPlayer.isPlaying()) mPlayer.stop();
            break;
    }
}

方法2
您还可以使用可运行的踏步或运行方法

Boolean IsPressed = false;
Button mbtn = (Button) findViewById(R.id.mbtn);

然后添加一个线程,在方法运行中添加此代码

@Override
public void run(){
      while(!btnIsPressed){
          myfunction();
      }
}

现在,在方法onCreate中,添加一个侦听器以将布尔值更改为true,例如这样

mbtn.addOnClickListener( new OnClickListener(){

   @Overrride
   public void onClick(View v){
      btnIsPressed = true;
   }
});

编辑：
我已经包含了另一个方法3,在这里,只要您触摸视图,我们就会运行一个线程,如果是否触摸了视图,它会检查isPress或不按下,然后重复声音,直到您从触摸中释放视图为止.

在这里,我为您发布了完整的代码

public class Soundstuff extends Activity implements OnTouchListener {
    SoundPool sP;
    boolean isPress = false;
    int gunshot = 0;
    private Handler handler = new Handler();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        View v = new View(this);
        setContentView(v);

        v.setOnTouchListener(this);

        sP = new SoundPool(2, AudioManager.STREAM_MUSIC, 0);
        gunshot = sP.load(this, R.raw.gunshot, 1);

    }

    private Runnable runnable = new Runnable() {

        @Override
        public void run() {
            /* do what you need to do */
            if (isPress) {
                sP.play(gunshot, 1, 1, 0, 0, 1);
                /* and here comes the "trick" */
                handler.postDelayed(this, 300);
            } else {
            }
        }
    };

    @Override
    public boolean onTouch(View v, MotionEvent event) {
        switch (event.getAction()) {
        case MotionEvent.ACTION_DOWN:
            isPress = true;
            handler.postDelayed(runnable, 300);
            break;

        case MotionEvent.ACTION_UP:
            isPress = false;
            handler.postDelayed(runnable, 300);
            break;
        }

        return true;
    }
}

希望这能解决您的问题.
