Hi, I did red
http://developer.android.com/guide/topics/ui/menus.html
http://developer.android.com/guide/topics/resources/menu-resource.html
I wrote this in main activity
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.mainmenu, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle item selection
switch (item.getItemId()) {
case R.id.infos:
infos();
return true;
case R.id.waring:
waring();
return true;
case R.id.credits:
credits();
return true;
case R.id.about:
about();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
private void about() {
// // TODO Auto-generated method stub
// // custom dialog
}
Where shoudd I put my alertbox (is this correct for a simple text box with no
button ?) :
new AlertDialog.Builder(this).setTitle("About").setMessage("el viva Android
!").create();
in private void about(), which never works
or directly in case R.id.about: about();
Quit lost here.
thks
