如何将图像作为AnimationDrawable的框架回收并解决Android中的OutOfMemory错误？

Question

我想用ViewPager在我的Android应用程序中显示一些练习。 我用：

• 2 imageView ，其中一个显示练习，另一个显示计数器

• AnimationDrawable

  当我退出我的应用程序时，它已经崩溃并显示了OutOFMemory错误。虽然android自动显示所有图像，但显示后如何recycle图像？

   public class NeckSportFinger extends Fragment { private ImageView sportShowing_img, timeShowing_img; public static AnimationDrawable animation_sport, animation_time; public TextView sportText; public NeckSportFinger(){} public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View view = inflater.inflate(R.layout.fragment_sport_show, container, false); sportShowing_img= (ImageView) view.findViewById(R.id.sport_img); timeShowing_img= (ImageView) view.findViewById(R.id.time_img); animation_sport = new AnimationDrawable(); animation_time = new AnimationDrawable(); animation_sport.addFrame(getResources().getDrawable(R.drawable.neck_one), 1500); //1 Sec animation_sport.addFrame(getResources().getDrawable(R.drawable.neck_one_right), 8500); //1 Sec animation_sport.addFrame(getResources().getDrawable(R.drawable.neck_one), 1500); //1 Sec animation_sport.addFrame(getResources().getDrawable(R.drawable.neck_one_left), 8500); //1 Sec animation_time.addFrame(getResources().getDrawable(R.drawable.t0), 1500); //1 Sec animation_time.addFrame(getResources().getDrawable(R.drawable.t1), 1500); //1 Sec animation_time.addFrame(getResources().getDrawable(R.drawable.t2), 1000); //1 Sec animation_time.addFrame(getResources().getDrawable(R.drawable.t3), 1000); //1 Sec animation_time.addFrame(getResources().getDrawable(R.drawable.t4), 1000); //1 Sec animation_time.addFrame(getResources().getDrawable(R.drawable.t5), 1000); //1 Sec animation_time.addFrame(getResources().getDrawable(R.drawable.t6), 1000); //1 Sec animation_time.addFrame(getResources().getDrawable(R.drawable.t7), 1000); //1 Sec animation_time.addFrame(getResources().getDrawable(R.drawable.t8), 1000); //1 Sec sportShowing_img.setBackgroundDrawable(animation_sport); timeShowing_img.setBackgroundDrawable(animation_time); sportText= (TextView) view.findViewById(R.id.sport_type); sportText.setText(R.string.sport_finger); return view; } public void start() { animation_sport.start(); animation_time.start(); } public void stop() { animation_sport.stop(); animation_time.stop(); } } 

谢谢！
