Title Body

I'm trying to possition my button not exactly in center, but let's say in the 2/5s of the screen height, I was looking for attribute unsuccessfully, so I tried this approach <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@drawable/background" android:padding="20dp" > <ImageButton android:id="@+id/flashlight_button" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerHorizontal="true" android:layout_above="@+id/fakeView" android:background="@null" android:contentDescription="@string/flashlight_button_description" android:src="@drawable/freeml_bright" /> <View android:id="@+id/fakeView" android:layout_width="10dp" android:layout_height="10dp" android:layout_centerInParent="true" android:background="#FFAABB" /> </RelativeLayout> However it does not work, even if I set margin on the fake view. Padding attribute works, however as it is a big image and if I want it to start at 2/5ths of screen height, it covers the center point of screen, so if I use padding attribute it works but it pushes it away from center and does not allow it to cover it. Alhough, I made it work using LinearLayout , which I wanted to avoid because there are more Views on top and bottom next to each other so it would lead to nested views using linear layout. Unfortunately I think its the only option. It basically it uses another linear layout that fills the remaining space left unused by top and bottom views with height=0dp and weight=1 and sets its gravity to center. <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layou
