Android - Vertical layout only

Question

How do I make sure my app is only for vertical layout?

I have tried android:screenOrientation=\"portrait\" but that doesn\'t seem to do the trick.

Answer 1

Activity is to block just in case want to block all and only repeat this line of code in their Activitys.

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_my);

    // Here, talk to the java does not want that the user can rotate their activity.

    this.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

or open your "AndroidManisfest.xml" and add the rows for the portrait mode as shown below.

        android:configChanges="orientation"
        android:screenOrientation="portrait">
