public class AndroidLocalize extends Activity {
Spinner spinnerctrl;
Button btn;
Locale myLocale;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
spinnerctrl = (Spinner) findViewById(R.id.spinner1);
spinnerctrl.setOnItemSelectedListener(new OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> parent, View view,
int pos, long id) {
if (pos == 1) {
Toast.makeText(parent.getContext(),
"You have selected Es", Toast.LENGTH_SHORT)
.show();
setLocale("ta");
} else if (pos == 2) {
Toast.makeText(parent.getContext(),
"You have selected Fr", Toast.LENGTH_SHORT)
.show();
setLocale("hi");
} else if (pos == 3) {
Toast.makeText(parent.getContext(),
"You have selected En", Toast.LENGTH_SHORT)
.show();
setLocale("en");
}
}
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
}
public void setLocale(String lang) {
myLocale = new Locale(lang);
Resources res = getResources();
DisplayMetrics dm = res.getDisplayMetrics();
Configuration conf = res.getConfiguration();
conf.locale = myLocale;
res.updateConfiguration(conf, dm);
Intent refresh = new Intent(this, AndroidLocalize.class);
