Changing Locale in Android Emulator
I am using the emulator with Android 4.2 + 4.3 and there is an app to set the locale called "Custom Locale".
Start emulator -> Launcher -> Custom Locale
=> Select the desired language from the list
=> Confirm with e.g "Select 'de_DE'"
I'm using 2.3.3, but it should be similar:
Start emulator -> Launcher -> Settings -> Language & keyboard -> Select language
My solution is to use preinstalled on android emulator "Custom locale" application. Simply send intent with extra language parameter to it as below:
adb shell am broadcast -a com.android.intent.action.SET_LOCALE --es com.android.intent.extra.LOCALE EN

No Need to change local, just long press on the EditText widget, on the popup menu select input method, and change to the android keyboard.
