In my PreferenceActivity I have this:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.settings);
setContentView(R.layout.preferences);
SharedPreferences sharedPreferences = getSharedPreferences("settings",
Context.MODE_PRIVATE);
sharedPreferences.registerOnSharedPreferenceChangeListener(new
OnSharedPreferenceChangeListener() {
@Override
public void onSharedPreferenceChanged(SharedPreferences
sharedPreferences, String key) {
Toast.makeText(getApplicationContext(), key, 0).show();
}
});
}
To test this solution. But I can't see any Toast.
