Android中Button被按下时的触发事件 [英] Triggering event when Button is pressed down in Android

问题描述

我有以下适用于 Android 的代码，单击按钮后可以正常播放声音:

I have the following code for Android which works fine to play a sound once a button is clicked:

Button SoundButton2 = (Button)findViewById(R.id.sound2);
        SoundButton2.setOnClickListener(new OnClickListener() {

    public void onClick(View v) {
        mSoundManager.playSound(2);

    }
});

我的问题是我希望在按下按钮(触地)时立即播放声音，而不是在松开时(触地).关于如何实现这一点的任何想法?

My problem is that I want the sound to play immediately upon pressing the button (touch down), not when it is released (touch up). Any ideas on how I can accomplish this?

推荐答案

也许使用 OnTouchListener?我猜 MotionEvent 会有一些方法来注册对象上的触摸.

Maybe using a OnTouchListener? I guess MotionEvent will have some methods for registering a touch on the object.

   button.setOnTouchListener(new OnTouchListener() {

    @Override
    public boolean onTouch(View v, MotionEvent event) {
     // TODO Auto-generated method stub
     return false;
    }
   }))
