I’ve found this question and I have almost the same problem. How could I apply alpha only to a relative layout and not to it’s children? Could anyone help?
I have a rectangular LinearLayout that has some margin, some round corners and an alpha value of 0.3. Inside this layout I have 4 different layouts as I display different images in different positions.
My issue is that although the primary layout is 0.3, I want my child to be fully visible, or not affected by it’s parent alpha, and I am wondering how I can please do that please? I have tried setting alpha=1 on the children layouts but it did not work. Setting it to 0 does make the children layout disappear though, so it seems I can reduce below 0.3 but not anything above the parent. Is that a bug or am I doing it wrong please?
Instead of setting the
alpha of the parent you can use
FrameLayout and set a background image first and set the
alpha of that child. For example
Instead of using this
<LinearLayout android:background="@drawable/background" android:alpha="0.3" > <LinearLayout> <Button /> <Button /> </LinearLayout> </LinearLayout >
Use this one
<FrameLayout> <ImageView android:background="@drawable/background" android:alpha="0.3" /> <LinearLayout> <Button /> <Button /> </LinearLayout> </FrameLayout>
