java.lang.RuntimeException: Canvas: trying to use a recycled bitmap android.graphics.Bitmap@412d7230

最近遇到了如标题这样的错误,再次记录解决方法。本文参考帖子:

http://bbs.csdn.net/topics/390196217

出现此bug的原因是在内存回收上,里面用Bitamp的代码为:

top=(ImageView)view.findViewById(R.id.top);
		bitmap=ImgBitmap.comeFromRes(getResources(), R.drawable. top);
		top.setImageBitmap(bitmap);
		bottom=(ImageView)view.findViewById(R.id.bottom);
		bitmap1=ImgBitmap.comeFromRes(getResources(), R.drawable. bottom);
		bottom.setImageBitmap(bitmap1);

在回收时,应该这样写:




@Override
	public void onDestroy() {
		// TODO Auto-generated method stub
		top.setImageBitmap(null);
		bottom.setImageBitmap(null);
		ImgBitmap.MyRecycle(bitmap);
		ImgBitmap.MyRecycle(bitmap1);
		super.onDestroy();
		
			
		
		
	}

或者

@Override
	public void onDestroy() {
		// TODO Auto-generated method stub
		ImgBitmap.MyRecycle(mBitmap);
		ImgBitmap.MyRecycle(mBitmap1);
		top=null;
		bottom=null;
		
		super.onDestroy();
		
			
		
		
	}

另外MyRecycle方法的代码如下:
public static void MyRecycle(Bitmap bmp){
		if(!bmp.isRecycled() && null!=bmp){
				bmp=null;
		}
		}
	}
	
总之是必须要解除与bitmap有关的所有绑定。
