I want to read strings from an xml
file before I do much of anything else like setText
on widgets, so how can I do that without an activity object to call getResources()
on?
Application
, for instance public class App extends Application {
android:name
attribute of your <application>
tag in the AndroidManifest.xml
to point to your new class, e.g. android:name=".App"
onCreate()
method of your app instance, save your context (e.g. this
) to a static field named mContext
and create a static method that returns this field, e.g. getContext()
:This is how it should look:
public class App extends Application{
private static Context mContext;
@Override
public void onCreate() {
super.onCreate();
mContext = this;
}
public static Context getContext(){
return mContext;
}
}
Now you can use: App.getContext()
whenever you want to get a context, and then getResources()
(or App.getContext().getResources()
).
