Custom dialog hasn't divider under the title

问题

At the official documentation there is an article of how to create custom dialogs. And there is also a picture of result dialog which have gradient border under it's title.

When I copy this code to run it on my machine and look at the results I get the dialog without gradient divider between the dialog's title and it's content:

Is this normal behavior and if it is, tell me how can I add divider by myself through the code, or using styles mechanism?

回答1:

Yes this is a normal behavior for custom dialog. To have the divider below title use something like:

    <View
    android:layout_width="fill_parent"
    android:layout_height="0.03dip"
    android:layout_marginLeft="5dip"
    android:layout_marginRight="5dip"
    android:layout_marginBottom="5dip"
    android:background="#404040" />

in your custom layout above the layout in which you have the imageview and textview.
