android - AnimationDrawable 以编程方式没有动画列表 xml

Question

我处于一种情况，我想显示动态图像列表中的动画。我想为此目的使用 AnimationDrawable，但不幸的是我被卡住了...... :( 我的代码是

ImageView globe = (ImageView) findViewById(R.id.globe);

AnimationDrawable animation = new AnimationDrawable();
animation.setOneShot(true);

Resources res = this.getResources();

while (from <= to) {
    String name = "globe_" + String.format("%03d", from);
    int globeId = res.getIdentifier(name, "drawable",
            this.getPackageName());
    animation.addFrame(res.getDrawable(globeId), 200);
    from++;
}

globe.setBackgroundDrawable(animation);
globe.post(new Runnable(){
        @Override
        public void run() {
            animation.start();
        }
});

Answer 1

我只是在循环之后执行了 animation.start() 并从一个可运行的对象中调用了该函数并且它起作用了

while (from <= to) {
    String name = "globe_" + String.format("%03d", from);
    int globeId = res.getIdentifier(name, "drawable",
            this.getPackageName());

    animation.addFrame(res.getDrawable(globeId), 200);
    from++;
}

globe.setBackgroundDrawable(animation);

animation.start()
