我处于某种情况,我想从动态图像列表中显示动画.我想使用AnimationDrawable为此目的,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();
}
});
解决方法
所以Animation.addFrame(Drawable frame,int duration)需要一个可以从Bitmap创建的drawable.
如果您的图像列表是动态加载的：
List<Bitmap> images;
int duration = 200;
for(Bitmap image: images){
BitmapDrawable frame = new BitmapDrawable(image);
animation.addFrame(frame,duration);
}
试试这个,一定要工作.
