Canvas: trying to use a recycled bitmap android.graphics....

实现播放幻灯片的效果时，出现如下问题：

Canvas: trying to use a recycled bitmap android.graphics.Bitmap@1c88f6a

if (bd != null && !bd.getBitmap().isRecycled()) {
    
    
                bd.getBitmap().recycle();
            }

改成

if (bd != null && !bd.getBitmap().isRecycled()) {
    
    
                bd = null;
            }

问题解决，已验证！！！
