Solution 1 :
I’m not quite sure what the problem is, but I’ve found a workaround which works for API 21.
has the same effect as
Solution 2 :
I think it might be a problem with
LinearLayout try to use
LinearLayoutCompat to support older API.
<androidx.appcompat.widget.LinearLayoutCompat android_layout_width="match_parent" android_layout_height="match_parent" android_background="@drawable/mybackground" android_backgroundTint="#ff0000" android_orientation="vertical"> <!--Sub views here--> </androidx.appcompat.widget.LinearLayoutCompat>
What’s the difference between LinearLayout and LinearLayoutCompat Here You can read a little about differences
I’ve been trying to apply a backgroundTint to a ConstraintLayout element having a Drawable background. However, the tint is not applied and the layout has the same background color as the drawable (only in API 21; works fine from API 23 upwards). It doesn’t work with LinearLayout and GridLayout either, so I think it might be something to do with ViewGroups. Here’s a simplified version of the element.
<LinearLayout android_layout_height="match_parent" android_layout_width="match_parent" android_orientation="vertical" android_background="@drawable/mybackground" android_backgroundTint="#ff0000"> <!--Sub views here--> </LinearLayout>
And here’s the background drawable.
<shape xmlns_android="http://schemas.android.com/apk/res/android"> <solid android_color="#ffffff"/> <corners android_radius="10dp"/> </shape>
How do I fix this?
