Question

I have a dialog box with two buttons at the bottom. How do I create a divider above these buttons? My XML is as follows:

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="wrap_content" 
android:layout_height="400dp" 
>   

<ImageView 
android:id="@+id/imageView2" 
android:layout_width="wrap_content" 
android:layout_height="wrap_content" 
android:layout_alignBottom="@+id/username" 
android:layout_alignParentLeft="true" />

<LinearLayout 
android:layout_width="wrap_content" 
android:layout_height="wrap_content" 
android:layout_alignParentBottom="true" 
android:layout_alignParentRight="true" 
android:orientation="horizontal"> 

<Button 
android:id="@+id/start" 
android:textSize="18sp" 
android:layout_marginRight="2dip" 
android:layout_width="wrap_content" 
android:layout_marginBottom="5dip" 
android:padding="5dip" 
android:layout_height="fill_parent" 
android:text="Start" /> 

<Button 
android:id="@+id/cancel" 
android:textSize="18sp" 
android:layout_marginLeft="2dip" 
android:layout_width="wrap_content" 
android:layout_height="wrap_content" 
android:text="Cancel" 
android:textColor="#000000" /> 

</LinearLayout> 
</RelativeLayout>

Answer 1

Simply add a ImageView and provide the following attribute,

 <ImageView  android:layout_width="fill_parent"
        android:layout_height="3dip"
        android:background="@color/white"
        android:padding="5dip"/>

There is nothing like a Divider attribute that you could set for a Layout. Dividers are available for ListView only.

So you might have to change your linear layout like this,

    <LinearLayout 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_alignParentBottom="true" 
    android:layout_alignParentRight="true" 
    android:orientation="horizontal"> 

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

  <ImageView  android:layout_width="fill_parent"
            android:layout_height="3dip"
            android:background="@color/white"
            android:padding="5dip"/>

</LinearLayout> 


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

    <Button 
    android:id="@+id/start" 
    android:textSize="18sp" 
    android:layout_marginRight="2dip" 
    android:layout_width="wrap_content" 
    android:layout_marginBottom="5dip" 
    android:padding="5dip" 
    android:layout_height="fill_parent" 
    android:text="Start" /> 

    <Button 
    android:id="@+id/cancel" 
    android:textSize="18sp" 
    android:layout_marginLeft="2dip" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:text="Cancel" 
    android:textColor="#000000" /> 

        </LinearLayout> 
    </LinearLayout>
