Android: How to make all elements inside LinearLayout same size?

I would like to create a dialog to display a video title and tags. Below text I would like to add buttons View, Edit and Delete and make these elements same size. Does anyone know how to modify .xml layout file in order to make elements inside LinearView same size?

The current layout file looks like this:

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" 
    android:orientation="vertical">

    <LinearLayout 
          android:layout_width="wrap_content" 
          android:layout_height="wrap_content" 
          android:orientation="vertical">

          <TextView 
              android:layout_width="wrap_content" 
              android:layout_height="wrap_content" 
              android:id="@+id/txtTitle" android:text="[Title]" >
          </TextView>

          <TextView 
              android:layout_width="wrap_content"
              android:layout_height="wrap_content" 
              android:id="@+id/txtTags"            
              android:text="[Tags]" >
          </TextView>

    </LinearLayout>

    <LinearLayout 
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content" 
        android:orientation="horizontal">

        <Button 
           android:layout_width="wrap_content" 
           android:layout_height="wrap_content" 
           android:id="@+id/btnPlay" 
           android:text="View">
        </Button>

        <Button 
            android:layout_width="wrap_content" 
            android:layout_height="wrap_content" 
            android:id="@+id/btnEdit" 
            android:text="Edit">
        </Button>

        <Button 
            android:layout_width="wrap_content" 
            android:layout_height="wrap_content" 
            android:id="@+id/btnDelete" 
            android:text="Delete">
        </Button>

    </LinearLayout>

</LinearLayout>

I would appreciate if anyone could show the solution by modifying the pasted file content.

Thanks!
