</LinearLayout>
</ScrollView>
<LinearLayout

android:layout_width="match_parent"
android:layout_height="wrap_content"

<Button
android:id="@+id/button1"

</LinearLayout>
</RelativeLayout>
I just need to do scroll my view and keep the button appeared on the screen at the bottom.
The problem is with
android:layout_above="@+id/bottomLinearLayout"
I get the error
Circular dependencies cannot exist in RelativeLayout
What is wrong with my layout?
Solution 1:
The problem is caused because there is a circular reference in the layout parameters.
For example, when view B is layout_below view A, view A can't reference view B anymore in it's below, alignRight etc. This can also exist between multiple views: A references B references C. In that scenario C can't reference A because of a circular dependency.
You Used :-
bottomLinearLayout is below scrollView1 And then you said that scrollView1 is above bottomLinearLayout
It dosen't work like that. Use one
Solution 2:
You cannot say the bottomLinearLayout is below scrollView1 then say scrollView1 is above bottomLinearLayout. Only do one, not both.
This is circular because it will try to position itself after it figures out where the other one is at... Which is waiting on the first one.
