Re: [android-developers] Can't layout square ImageButtons

Don't set layout_weight=1 on the buttons.

Insert four Views between the buttons to act as spacers, and give those
layout_weight:

<ImageButton..../>

<View
android:layout_width="0px"
android:layout_height="1px"
android:layout_weight="1"/>

<ImageButton.../>

<View
android:layout_width="0px"
android:layout_height="1px"
android:layout_weight="1"/>

etc.
