我在我的应用程序的许多活动中使用animationdrawables.这是对他们进行初步化的代码:
public void prepareVideo (int resourceBall, String animation, int width, int height ){
imgBall = (ImageView)findViewById(resourceBall);
imgBall.setVisibility(ImageView.VISIBLE);
String resourceNameAnimation = animation;
int id_res = getResources().getIdentifier(resourceNameAnimation, "drawable", getPackageName());
imgBall.setBackgroundResource(id_res);
LayoutParams latoutFrame = imgBall.getLayoutParams();
latoutFrame.width = width;
latoutFrame.height = height;
imgBall.setLayoutParams(latoutFrame);
frame = (AnimationDrawable) imgBall.getBackground();
}
然后我调用:imgBall.post(new StartAnimation());
调用runnable:
class StartAnimation implements Runnable {
public void run() {
frame.start();
}
}
问题是我使用了许多动画,它们使用相同的xml(逐帧).我必须在具有相同动画的许多活动中调用此方法.最后,我得到了一个错误的错误.我试图在屏幕之间释放内存:
for (int i = 0; i < frame.getNumberOfFrames(); ++i){
Drawable frame_rescue = frame.getFrame(i);
if (frame_rescue instanceof BitmapDrawable) {
((BitmapDrawable)frame_rescue).getBitmap().recycle();
} …
