如何启动animationdrawable onTouch？

Question

我有猫动画跳跃，它有5个绘图，我想触摸猫，使它跳跃。

如果android的oneshot=为“假”，那么在触摸猫之后，它会一直跳个不停。

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.page5);
    cat_jump = (ImageView)findViewById(R.id.cat_jump);
    cat_jump.setBackgroundResource(R.drawable.cat_jumping_animation);

    final AnimationDrawable frameAnimation = (AnimationDrawable) cat_jump.getBackground();

    cat_jump.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            frameAnimation.start();
        }
    });

Answer 1

在create上创建这个

    ImageView iv = (ImageView)findViewById(R.id.cat_jump);
    AnimationDrawable aw = (AnimationDrawable) iv.getBackground();

    aw.stop();
    aw.start();

然后,

public void Start() {
    aw.stop();
    aw.start();
}

public void Stop() {
    aw.stop();

}
