Answer 1

ok, here's a revised example:

<?xml version="1.0" encoding="utf-8"?>
<ViewFlipper xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_height="fill_parent" android:layout_width="fill_parent">
    <RelativeLayout android:id="@+id/magaLoginLayout"
        android:layout_height="fill_parent" android:layout_width="fill_parent">
        <Button android:text="@+id/Button01" android:id="@+id/Button01"
            android:layout_width="160dip" android:layout_height="160dip" android:layout_marginTop="20dip"></Button>
        <Button android:text="@+id/Button03" android:layout_below="@+id/Button01" android:id="@+id/Button03"
            android:layout_alignLeft="@+id/Button01" android:layout_height="160dip" android:layout_width="160dip"></Button>
        <Button android:text="@+id/Button04" android:layout_below="@+id/Button01" android:id="@+id/Button04"
            android:layout_toRightOf="@+id/Button03" android:layout_height="160dip" android:layout_width="160dip"></Button>
        <Button android:text="@+id/Button02" android:id="@+id/Button02" android:layout_width="wrap_content"
            android:layout_toRightOf="@+id/Button01" android:layout_alignTop="@+id/Button01" android:layout_alignParentRight="true" android:layout_height="160dip"></Button>


</RelativeLayout>

</ViewFlipper>

import android.content.Context; import android.util.AttributeSet; import android.widget.LinearLayout;

public class SquareLayout extends LinearLayout {

public SquareLayout(Context context) {
    super(context);
}

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

@Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {

    int width = MeasureSpec.getSize(widthMeasureSpec);
    int height = MeasureSpec.getSize(heightMeasureSpec);

    if (width > (int)(mScale * height + 0.5)) {
        width = (int)(mScale * height + 0.5);
    } else {
        height = (int)(width / mScale + 0.5);
    }

    super.onMeasure(
            MeasureSpec.makeMeasureSpec(width, MeasureSpec.EXACTLY),
            MeasureSpec.makeMeasureSpec(height, MeasureSpec.EXACTLY)
    );
}

}
