java - Android 拖动/动画

Question

我想制作一个页面，您可以在其中拖动图像（并播放一些动画）

所以我正在做某事（我认为这并不理想 - 所以我需要你的帮助）：

我的代码：

ButtonIMG = BitmapFactory.decodeResource(getResources(), R.drawable.ButtonIMG );
Canvas c = null;
while (true) {
    if (!holder.getSurface().isValid()) {
        continue;
    }
    if (gifCounter<10){
        animataion = BitmapFactory.decodeResource(getResources(), R.drawable.animataion1);
        gifCounter++;
    }
    if (gifCounter<20 && gifCounter>=10){
        animataion = BitmapFactory.decodeResource(getResources(), R.drawable.animataion2);
        gifCounter++;
    }
    if (gifCounter<30 && gifCounter>=20){
        animataion = BitmapFactory.decodeResource(getResources(), R.drawable.animataion3);
        gifCounter++;
    }
    if (gifCounter>=30){
        gifCounter=0;
    }
    c = holder.lockCanvas();
    c.drawARGB(255, 220, 220, 220);
    c.drawBitmap(ButtonIMG, x, y, null);
    c.drawBitmap(animataion, 100, 100, null);
}

. . .

public boolean onTouch(View v, MotionEvent me){
    switch (me.getAction()) {
        case MotionEvent.ACTION_DOWN:
            x = me.getX();
            y = me.getY();
            break;
    }
}
