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!

Use android:layout_width="0px" and android:layout_weight="1" on the three Buttons. That says the buttons should take up no more than 0 pixels, but the three of them should split any extra space between them. That should give you the visual effect you wish.

Another way is to make android:layout_width="fill_parent" and android:layout_weight="1" this will also works fine!!!

Use LinearLayout with your desired weightSum and create elements with equal layout_weight. Here is an example ...

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:weightSum="5">

    <ImageView
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:src="@drawable/ic_share_white_36dp"/>

    <ImageView
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:src="@drawable/ic_search_white_36dp"/>

    <ImageView
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:src="@drawable/ic_event_note_white_36dp"/>

    <ImageView
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:src="@drawable/ic_brush_white_36dp"/>

    <ImageView
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:src="@drawable/ic_menu_white_36dp"/>
</LinearLayout>

So, the weight sum of all elements is 5. Here is the screenshot ...

Note that, Google Material Design icons are used. Hope this is helpful.
