Regarding removal of Activity Title bar in Android

Question

i have already set the theme of my activity as android:theme = "@android:style/Theme.Dialog" but i also want to remove the title bar of the activity. so how to use android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen" along with the dialog theme.

Answer 1

Try creating a custom style that extends Theme.Dialog:

<resources>
    <style name="DialogNoTitle" parent="android:Theme.Dialog">
        <item name="android:windowNoTitle">true</item>
    </style>
</resources>

Answer 2

I believe you can specify this in your activity's onCreate():

requestWindowFeature(Window.FEATURE_NO_TITLE);
