Android: listen for Orientation change?

Question

How would I listen for orientation change in Android? and do certain things when the user has switched to landscape?

Answer 1

You have a couple of choices:

• Use an OrientationEventListener, which has a method called onOrientationChanged.

• Use config changes:

In your Manifest, put:

<activity android:name=".HelloAndroid"     android:label="@string/app_name"     android:configChanges="orientation"> 

And, in your Activity, override onConfigurationChanged:

@Override public void onConfigurationChanged(Configuration newConfig) {     super.onConfigurationChanged(newConfig);      int newOrientation = newConfig.orientation;      if (newOrientation == Configuration.ORIENTATION_LANDSCAPE) {       // Do certain things when the user has switched to landscape.         }    } 

Here is a good tutorial about it.

Answer 2

In your activity, you can override this method to listen to Orientation Change and implement your own code.

public void onConfigurationChanged (Configuration newConfig) 

The Configuration Class has an int constant ORIENTATION_LANDSCAPE and ORIENTATION_PORTRAIT, there for you can check the newConfig like this:

super.onConfigurationChanged(newConfig);

int orientation=newConfig.orientation;  switch(orientation) {  case Configuration.ORIENTATION_LANDSCAPE:  //to do something  break;  case Configuration.ORIENTATION_PORTRAIT:  //to do something  break;  }
