RelativeLayout layout_centerInParent and layout_below issue

up vote 2 down vote favorite

I have a problem with laying out a Relative Layout. Here is the test code <RelativeLayout android:background="@drawable/bg_controls" android:layout_width="fill_parent" android:layout_height="wrap_content"> <LinearLayout android:id="@+id/controls_layout" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_centerInParent="true" android:gravity="center"> <Button android:layout_width="wrap_content" android:layout_height="wrap_content" /> </LinearLayout> <Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@id/controls_layout" /> </RelativeLayout> The result of that is  If I remove android:layout_centerInParent="true" everything works OK. Why does RelativeLayout fails to do that otherwise? UPD: the intended result is that a second button appears under the LinearLayout. android  android-layout  relativelayout share | improve this question asked  May 16 '11 at 19:51 Kostia Dombrovsky 481 7 21

What is the intended result? –   prolink007  May 16 '11 at 19:54 What exactly are you trying to make it do? –   FoamyGuy  May 16 '11 at 19:54 the intended result is that a second button appears under the LinearLayout. I thought that was obvious... –  Kostia Dombrovsky  May 16 '11 at 19:56 by under the linearlayout, do you mean below the linearLayout? –   PravinCG  May 16 '11 at 19:57 Can you be a little more specific regarding the image itself instead of the layouts? –   prolink007  May 16 '11 at 19:58 show 3 more comments

I was having a very similar issue, where I had a centered View that was designated layout_centerInParent, and all my other Views were relative to that, but some of the Views were not rendering properly in the editor or on the device. I found that my centered View itself, designated layout_centerInParent, still had to be relative to something else (as unintuitive as that sounds). So I made it layout_below something that was on top of it, even though that View on top of it was not aligned to anything except being layout_top of the same thing below. But once I did this, the whole UI snapped into place :) share | improve this answer answered  Sep 6 at 6:41 occorled 131 12
