AnimationDrawable编程无动画列表XML [英] AnimationDrawable programmatically without animation-list xml

问题描述

我在一个情况下，我希望显示图像的动态列表动画。我想用AnimationDrawable用于此目的，但不幸的是我坚持... :(我的code是为

  ImageView的地球=（ImageView的）findViewById（R.id.globe）;

AnimationDrawable动画=新AnimationDrawable（）;
animation.setOneShot（真正的）;

资源RES = this.getResources（）;

而（来自以下; =到）{
    字符串名称=globe_+的String.Format（％03D，​​从）;
    INT globeId = res.getIdentifier（姓名，绘制，
            this.getPackageName（））;
    animation.addFrame（res.getDrawable（globeId），200）;
    从++;
}

globe.setBackgroundDrawable（动画）;
globe.post（新的Runnable（）{
        @覆盖
        公共无效的run（）{
            animation.start（）;
        }
}）;
 

解决方案

我只是做了 animation.start（）循环后，并从一个可运行调用的函数，它工作

 同时（从＆LT; =到）{
    字符串名称=globe_+的String.Format（％03D，​​从）;
    INT globeId = res.getIdentifier（姓名，绘制，
            this.getPackageName（））;

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

globe.setBackgroundDrawable（动画）;

animation.start（）
 

I am in a situation where I want to display animation from dynamic list of images. I want to use AnimationDrawable for this purpose, but unfortunately I am stuck... :( my code is as

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();
        }
});

解决方案

I just did animation.start() after the loop and called the function from a runnable and it worked

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()
