您可以在回收位图之前进行检查，例如：

if (img != null && !img.isRecycled()) 
{
 img.recycle(); 
 img = null;
 System.gc(); 
}

这里的img 是位图。试试这个类型错误就解决了。

Try to find references of usage of the method recycle() in your code or in any library that you use. It indicates that someone is recycling a bitmap that is still being used which is not good. You can only safely call the recycle() method when you are absolutely sure that the given bitmap won't be necessary anymore.

It is usually a common problem when you are dealing with bitmap caches, not sure if that is your case.

此处已提供解决方案：画布：尝试在 android 中使用回收的位图 android.graphics.Bitmap

这个应该工作。否则，请查看链接以获取更多解决方案

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