java - 如何在按下 ImageView 时立即启动音频？

Question

我的代码仅在 ImageView 释放时播放音频。我应该添加什么才能使音频在按下时立即开始？

MediaPlayer mp = null;

public void next (View view) {
    if (mp != null) {
        mp.stop();
        mp.release();
    }
    mp = MediaPlayer.create(this, R.raw.dry);
    mp.start();
}

XML 代码:

<ImageView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:src="@drawable/seethrough"
    android:clickable="true"
    android:id="@+id/Seethrough"
    android:onClick="next"
    />

Answer 1

您应该使用如下所示的内容

ImageView seethrough= (ImageView)this.findViewById(R.id.Seethrough);
seethrough.setOnTouchListener(new OnTouchListener()
    {
        @Override
        public boolean onTouch(View v, MotionEvent event)
        {
            if (event.getAction() == MotionEvent.ACTION_DOWN)
                // this is where you should call next()
            else if (event.getAction() == MotionEvent.ACTION_UP)
                  // this is if you are interested in the release action 
            return false;
        }
    });
