布局重绘的事暂且不提。因为view的测量数据会缓存起来,所以不重绘应该也可以在resize之后正常显示才对,所以看了一下GridImageView,发现问题在onDetachedFromWindow的时候进行了setImageDrawable(null)的操作图片被清空所导致。

这样的话,上边没有重绘的问题也找到了

public void setImageDrawable(@nullable Drawable drawable) {
if (mDrawable != drawable) {
mResource = 0;
mUri = null;
final int oldWidth = mDrawableWidth;
final int oldHeight = mDrawableHeight;

        updateDrawable(drawable);

        if (oldWidth != mDrawableWidth || oldHeight != mDrawableHeight) {
            requestLayout();
        }
        invalidate();
    }
}

null导致没有requestLayout
