How To Remove The Upper Grey Bar In This App?

Can anybody tell me how to remove that grey bar in app containing the app name..

Solution 1:

You can add this line in your menifest -

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

for full screen use below -

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

If you want to do it programatically use below code -

publicclassActivityNameextendsActivity {
    @OverridepublicvoidonCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // remove title
        requestWindowFeature(Window.FEATURE_NO_TITLE);

        setContentView(R.layout.main);
    }
}

for full screen -

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);

Use according to your feasibility.

Solution 2:

<applicationandroid:theme="@style/AppTheme">

style.xml

<resources> Add below here </resources>
