    <p>I have to change the language on runtime in Android (yes, I know that this is not a good behaviour, but this is a requirement...).</p> <p>So I have a basic class, from which every activity extends. This class has the following function:</p> <pre><code>public static void changeLanguage(Context context) { Resources res = context.getResources(); /* * Change locale settings in the app. */ DisplayMetrics dm = res.getDisplayMetrics(); /* * Store and load data in this preferences */ android.content.res.Configuration conf = res.getConfiguration(); String[] localArray = res.getStringArray(R.array.language_short_array); if (localArray != null) { SharedPreferences settings = context.getSharedPreferences( MyService.APP_ID, MODE_PRIVATE); conf.locale = new Locale(localArray[settings.getInt( PREFERED_LANGUAGE_KEY, 0)]); res.updateConfiguration(conf, dm); } } </code></pre> <p>I will call this method in onCreate:</p> <pre><code>@Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); changeLanguage(this); } </code></pre> <p>This is in the super-class. My Activities extends from it and call super.onCreate at first. After this call, they set their layout and initializes their settings...</p> <p>I thought that my lines of code would make it. But I have the following problem: Sometimes, the activity changes the language and sometimes not!</p> <p>If I set a debug breakpoint on it and after the programm pauses I press continue, everything works fine. So I think, in some cases, where my Application is "slow enough", the language will change correctly, whereas the language won't change if the application is too fast...</p> <p>Is there any solution of my problem? How can I be sure, that my language will change correctly in any time?</p> <p>Thanks a lot!</p> <p>Edit: Here is an example for a class which extends from my super-class</p> <pre><code>public class MainMenuActivity extends BaseActivity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_start); } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
