Mandate Android Application to Start Portrait Only, BUT ability to rotate when running

I have an application that 开发者_JS百科I want to start only in portrait, but once it has begun allow for configuration change. The content of the landscape mode is a map image that relates to the information on the portrait view.

you could start you activity in portrait mode using

<activity
  android:name=".ui.FrmSignature"
  android:label="@string/frmsignature_lblTitle"
  android:screenOrientation="portrait"
/>

and then, inside your code, you can link the orientation change to device position setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR).

You can do it by using android:screenOrientation="portrait" in your Manifest file.

Just add android:screenOrientation="portrait to your activity Tag in which you'd like to show Portrait..

<activity android:name=".Keydets_Main" android:label="@string/app_name" android:icon="@drawable/keydets_icon" android:screenOrientation="portrait" />

If you add this for Particular Activity , only that activity will comes in Portrait Mode.

If you Specify inside of Application Tag it will applicable for whole app.
