title: Get width of linear/relative layout?
body: <p>Is it possible to get the width of a linear/relative layout, if the layout_width is set to fill_parent in the layout xml? For example, I have the following layout xml. Is it possible to find the width of the cameraSourceScreen? Thanks in advance :)</p>
  
  <pre><code>&lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  android:id="@+id/CameraSourcesScreen"
  &gt;
  
  &lt;LinearLayout android:id="@+id/button_bar"
  android:layout_height="wrap_content"
  android:layout_width="fill_parent"
  android:layout_alignParentTop="true"
  android:layout_alignParentLeft="true"
  android:background="@drawable/topbar"
  android:orientation="horizontal"
  android:gravity="center"&gt;
  
  &lt;LinearLayout android:layout_height="wrap_content"
    android:layout_width="fill_parent"
    android:orientation="horizontal" android:paddingLeft="20dp"&gt;
  
          &lt;common.view.ToggleButton android:id="@+id/Near_Toggle"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginRight="2dp"
            android:layout_alignParentLeft="true"
            android:layout_centerVertical="true" android:text="@string/NEAR_STR"
            android:textSize="18px" android:width="130dp"/&gt;
  
    &lt;common.view.ToggleButton android:id="@+id/Far_Toggle"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginRight="2dp"
            android:layout_alignParentLeft="true"
            android:layout_centerVertical="true" android:text="@string/FAR_STR"
              android:textSize="18px" android:width="130dp"/&gt;
  
  &lt;/LinearLayout&gt; &lt;/LinearLayout&gt; &lt;/RelativeLayout&gt;
