title: android text view(s) overlayed with button
body: <p>within a linear layout i need to overlay some text views with a transparent button which fills the whole layout size (width/height). I tried with match parent layout properties but that doesn't work. Thank You for your help.</p>
  
  <pre><code>&lt;LinearLayout
                  android:id="@+id/layout1"
                  android:layout_width="38dp"
                  android:layout_height="match_parent"
                  android:gravity="bottom"
                  android:orientation="vertical" &gt;
  
                  &lt;TextView
                      android:id="@+id/TVBlack"
                      android:layout_width="28dp"
                      android:layout_height="wrap_content"
                      android:layout_gravity="center|bottom"
                      android:background="@color/black"
                      android:text="test"
                      android:textColor="@color/white" /&gt;
  
                  &lt;TextView
                      android:id="@+id/TVWhite"
                      android:layout_width="28dp"
                      android:layout_height="wrap_content"
                      android:layout_gravity="center|bottom"
                      android:text="test"
                      android:textColor="@color/black" /&gt;
  
                  &lt;Button
                      android:id="@+id/button1"
                      android:layout_width="match_parent"
                      android:layout_height="match_parent"
                      android:background="@null"
                      android:text="Button" /&gt;
  
              &lt;/LinearLayout&gt;
