Android Custom Intent Select the title of the interface

You can use the Intent.createchooser () method to create a Intent and pass in the desired Sting as the caption.
Taking the wallpaper selection box as an example, when you press on a blank area in Launcher workspace, a wallpaper selection box pops up, and the selection box is titled "Choose Wallpaper from", as follows:

private void Startwallpaper () {
Showworkspace (TRUE);
Final Intent pickwallpaper = new Intent (intent.action_set_wallpaper);
Intent chooser = Intent.createchooser (Pickwallpaper, GetText (R.string.chooser_wallpaper));
Note:adds A configure option to the Chooser if the wallpaper supports it
Startactivityforresult (Chooser, Request_pick_wallpaper);
}

where the r.string.chooser_wallpaper corresponding string content is "Choose wallpaper from", defined in Launcher2 strings.xml
