Question

how can i remove these application bar at the top of any android app which i create? in the case that it is not possible, is it possible to change it? (i don't mean the text, i mean the layout and style)

Answer 1

You can use this call on the onCreate method of the activity

requestWindowFeature(Window.FEATURE_NO_TITLE);

Answer 2

If i understand your problem, then it's very simple.

Just add this line, to your activity (in the manifest xml file) :

android:theme="@android:style/Theme.NoTitleBar"

For example :

<activity android:name=".TestActivity"

android:theme="@android:style/Theme.NoTitleBar">
<intent-filter>
    <action android:name="android.intent.action.MAIN" />
</intent-filter>

</activity>
