android - Changing locale: Force activity to reload resources?

Question

So I have a language setting in my application. When the language is switched, I would like all the textviews etc to change language immediately. Currently I just change the locale in the configuration, so the language has changed when the user restarts the activity.

An ugly solution to my problem would be to make each textview load the new resources each time the language is changed. Is there a better solution? Perhaps a neat way to discretely restart the activity? Or maybe just force reload of the resources?

Answer 1

In your AndroidManifest.xml, add this attribute to your Activity

android:configChanges="locale"

In your activity override onConfigurationChanged()

@Override
public void onConfigurationChanged(Configuration newConfig) {
  // refresh your views here
  super.onConfigurationChanged(newConfig);
}
