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();
		
			
		
		
	}

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

public static void MyRecycle(Bitmap bmp){
		if(!bmp.isRecycled() && null!=bmp){
				bmp=null;
		}
		}
	}
