Answer: 
The simplest approach is, in my opinion, to subclass the the Layout you want squared, overriding onMesure. For instande:

```
public class SquaredLayout extends LinearLayout {

public SquaredLayout(Context context, AttributeSet attrs) {
    super(context, attrs);
}

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    super.onMeasure(widthMeasureSpec, widthMeasureSpec);
}
}

```
Hava you try write a selector.xml to sharp a cornor background?
maybe that will helps you.
