Android internationalization (forced conversion language within the Program)

First, let's take a look:

 

Project Structure:

 

Android 3.0 and earlier versions:

Import java. util. locale;
Import Android. App. activity;
Import Android. App. alertdialog;
Import Android. content. context;
Import Android. content. dialoginterface;
Import Android. content. intent;
Import Android. content. sharedpreferences;
Import Android. content. sharedpreferences. Editor;
Import Android. content. res. configuration;
Import Android. content. res. Resources;
Import Android. OS. Bundle;
Import Android. OS. Handler;
Import Android. OS. message;
Import Android. View. view;
Import Android. widget. adapterview;
Import Android. widget. adapterview. onitemselectedlistener;
Import Android. widget. arrayadapter;
Import Android. widget. Button;
Import Android. widget. spinner;

Public class hellomyl10nactivity extends activity {
Private sharedpreferences preferences;

@ Override
Public void oncreate (bundle savedinstancestate ){
Super. oncreate (savedinstancestate );
// If (savedinstancestate = NULL ){
// Savedinstancestate = getintent (). getbundleextra ("instance ");
// If (savedinstancestate! = NULL ){
// Onrestoreinstancestate (savedinstancestate );
//}
//}
Preferences = getsharedpreferences ("Lang", context. mode_private );
String langstring = preferences. getstring ("Lang", "en ");
Setlanguage (langstring );
Setcontentview (R. layout. Main );

Button B;
(B = (button) findviewbyid (R. Id. flag_button). setbackgrounddrawable (this. getresources (). getdrawable (R. drawable. Flag ));

// Language selection
Final string Lang [] = new string [] {"en", "FR", "de", "Ja "};
String items [] = new string [] {"English", "French", "German", "Japanese "};
Spinner spinner = (spinner) findviewbyid (R. Id. chooselang );
Spinner. setadapter (New arrayadapter <string> (this, Android. R. layout. simple_spinner_item, items ));
If (preferences. getint ("Lang", 0 )! = 0 ){
Spinner. setselection (savedinstancestate. getint ("position"), true );
}
Spinner. setonitemselectedlistener (New onitemselectedlistener (){

@ Override
Public void onitemselected (adapterview <?> Parent, view,
Int position, long ID ){
If (! (Preferences. getstring ("Lang", "en"). Equals (Lang [position]) {
Setlanguage (Lang [position]);
Editor editor = preferences. Edit ();
Editor. putstring ("Lang", Lang [position]). Commit ();

Intent intent = new intent (hellomyl10nactivity. This, hellomyl10nactivity. This. getclass ());
Startactivity (intent );
Finish ();
}

}

@ Override
Public void onnothingselected (adapterview <?> Parent ){
// Todo auto-generated method stub
}
});
}


Private void setlanguage (string langstring ){

Resources resources = getresources ();
Configuration Config = resources. getconfiguration ();
Locale locale = new locale (langstring );
Locale. setdefault (locale );
Config. locale = locale; // Simplified Chinese
Resources. updateconfiguration (config, null );
}

}

This method does not work when it comes to Android 4.0. The text effect is still internationalized, but the image is not internationalized.

 

I recommend a blog http://blog.csdn.net/a_colt/article/details/6193857 to check whether the problem exists.

"But at the same time I found a problem.

If a button event is triggered

The directory button generated in the same activity does not work, but does work for the dialog box that has not yet been generated before triggering. Do you need to refresh the directory menu to generate after triggering? "

 

Finally, upload a tool class for international conversion. The following configurations are required for use:/files/lee0oo0/languagesettingutil.rar

Categoragesettingutil. INIT (getactivity (); categoragesetting = categoragesettingutil. Get (); // get the final string cursyslanguage = locale. getdefault (). getlanguage ();

Deleagesetting. checksyschanged (cursyslanguage );

 

// Set the language for replacement

Receivagesetting. savelanguage ("ZH ");

// Update

Languagesetting. refreshlanguage ();
