Android实时壁纸中的触摸事件

Question

我想在Android中建立水族馆应用程序实时壁纸，在其中我绘制多个位图，现在我想添加触摸事件，当我触摸鱼时，我应该如何反应，我可以如何知道哪个特定的鱼被触摸，我可以如何做

private void draw() {
    final SurfaceHolder holder = getSurfaceHolder();
    Canvas C = null;
    try {
        C = holder.lockCanvas();
        c.drawColor(Color.BLACK);
        if (c != null) {
            if (playingcounter3 == 20) {
                playingcounter3 = 0;
            }
            c.drawBitmap(fish_c[1][playingcounter3], x1, 200, null);
            if (x > width) {
                x = -f1_width - width / 7;

            }
        }
    } finally {
        if (c != null) holder.unlockCanvasAndPost(c);
    }
    handler.removeCallbacks(drawRunner);
    if (visible) {
        handler.postDelayed(drawRunner, 10);
    }
}

您必须检查on touch事件的像素值。

@Override
public void onTouchEvent(MotionEvent event) 
{
     if (event.getAction() == MotionEvent.ACTION_DOWN) 
     {                         
       event.getX();   
       event.getY();   
     }           

    super.onTouchEvent(event);
}
