如何解决这个问题我已经试过这code，但还是不知道该怎么办？

How to solve this problem I have tried this code but still not knowing what to do?

 @Override
    protected void onDestroy() {
    super.onDestroy();

    unbindDrawables(findViewById(R.id.rootView));
    System.gc();
    }

    private void unbindDrawables(View view) {
        if (view.getBackground() != null) {
        view.getBackground().setCallback(null);
        }
        if (view instanceof ViewGroup) {
            for (int i = 0; i < ((ViewGroup) view).getChildCount(); i++) {
            unbindDrawables(((ViewGroup) view).getChildAt(i));
            }
        ((ViewGroup) view).removeAllViews();
        }
    }

什么是解决这一问题的可能途径？请帮助

推荐答案

优化位图的内存使用的情况下，最好的办法就是保存ImageViews列表使这个为每个ImageView的调用完成（）之前：

The best way to optimize memory usage with bitmaps in your case is to save a list of your ImageViews make this before call finish() for every ImageView:

((BitmapDrawable) myImageView.getDrawable()).getBitmap().recycle();
myImageView = null;

使用过的code。在的onPause code，与具有ID的活动的主要布局 top_layout ：

Use too the code in onPause code, with the main layout of your activity having the id top_layout:

@Override
protected void onPause() {
    super.onPause();
    unbindDrawables(findViewById(R.id.top_layout));
    System.gc();
}
