android imageview回收,android – ImageView：如果ImageView不可见,则自动回收位图(在ScrollView中)...

如果要回收位图,请调用此方法.

public static void recycleImagesFromView(View view) {

if(view instanceof ImageView)

{

Drawable drawable = ((ImageView)view).getDrawable();

if(drawable instanceof BitmapDrawable)

{

BitmapDrawable bitmapDrawable = (BitmapDrawable)drawable;

bitmapDrawable.getBitmap().recycle();

}

}

if (view instanceof ViewGroup) {

for (int i = 0; i < ((ViewGroup) view).getChildCount(); i++) {

recycleImagesFromView(((ViewGroup) view).getChildAt(i));

}

}

}
