How dismiss parent padding in children element

Question

I have FrameLayout and for most fragments the parrent padding is good. But I have especial fragment which must not contain the padding.

<FrameLayout
    android:id="@+id/frame_content"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="10dp"
    />

<!-- My especial fragment -->
<LiearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="-10dp"
/>

Any suggestions!

Answer 1

Curious, just using layout_margin does not seem to work. However,

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
         android:layout_width="match_parent"
         android:layout_height="match_parent"
         android:padding="10dp"
         android:clipToPadding="false">
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_marginTop="-10dp"
        android:layout_marginStart="-10dp"
        android:layout_marginEnd="-10dp"
        android:layout_marginBottom="-10dp" />
</FrameLayout>

seems to work (IntelliJ android preview).

Do not forget: android:clipToPadding="false" in the parent layout.

Seems like things would be easier if you would just remove the android:padding="10dp" from your FrameLayout and in your "normal" fragments you add the 10dp padding, while in your "special" fragment you don't add any padding. Negative margins can be done, but in my opinion should only be used if there is no other way to do it.
