Question

使用自定义布局作为导航抽屉中的菜单项时遇到一些麻烦。当我使用img_base_cvt = cv2.cvtColor(base_img_rgb,cv2.COLOR_BGR2GRAY) base_img = cv2.GaussianBlur =(img_base_cvt, (5,5), 0) # Use the SIFT feature detector detector = cv2.xfeatures2d.SIFT_create() # Find key points in base image for motion estimation base_features, base_descs = detector.detectAndCompute(base_img, None)时，只会显示一个标题。

我通过在 drawer_menu_footer.xml

中将app:srcCompat替换为android:background来解决了我的问题

actionLayout不显示在导航抽屉中
