How To Handle Orientation Change Easily

I'm working on a android application that adds every view programmaticaly. When the user turns the screen, I just want to values that are filled in to be displayed again. Is there

Solution 1:

Everytime orientation change, android create new view and destroy the old one. You can saved your data when orientation change and re-initialize when the new view is created

Use onConfigurationChanged method of activity to detect Orientation Change

public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);

    // Checks the orientation of the screen
    if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
        Toast.makeText(this, "landscape", Toast.LENGTH_SHORT).show();
    } else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT){
        Toast.makeText(this, "portrait", Toast.LENGTH_SHORT).show();
    }
  }

Don't forget to edit the appropriate element in your AndroidManifest.XML like this to include the android:configChanges

<activityandroid:name=".MyActivity"android:configChanges="orientation|keyboardHidden"android:label="@string/app_name">
