Android determine screen orientation at runtime

Question

Here\'s a pseudo code to detect screen rotate event, and decide to retain or changes the screen orientation.

public boolean onOrientationChanges(orientation) {
          


        

Answer 1

Try running

getResources().getConfiguration().orientation

From your context object to figure out what is the screen orientation at runtime, the possible values are documented here

In order to catch the orientation change event you can find the answer in the Android Dev Guide: Handling the Configuration Change Yourself

From the guide :

For example, the following manifest code declares an activity that handles both the screen orientation change and keyboard availability change:

android:configChanges="orientation|keyboardHidden"
android:label="@string/app_name">

Now, when one of these configurations change, MyActivity does not restart. Instead, the MyActivity receives a call to onConfigurationChanged(). This method is passed a Configuration object that specifies the new device configuration. By reading fields in the Configuration, you can determine the new configuration and make appropriate changes by updating the resources used in your interface. At the time this method is called, your activity's Resources object is updated to return resources based on the new configuration, so you can easily reset elements of your UI without the system restarting your activity.
