Objective:

The exit program used earlier uses finish (), which only exits the current activity. If you have more than one activity, you can't quit at once.

1. Exit the Application Tools class

/** *  * @author itas109 * TODO is used to completely exit the application  */public class Exitapputils extends application {    private List<ac tivity> activitylist = new linkedlist<activity> ();    private static exitapputils instance;      Private Exitapputils () {    }      //In singleton mode gets the unique Exitapputils instance public    static Exitapputils getinstance () {        if ( NULL = = Instance) {            instance =new exitapputils ();        }        return instance;    }      Add activity to container public    void addactivity (activity activity) {        activitylist.add (activity);    }      Traverse all Activity and finish public      void exit () {for        (Activity activity:activitylist) {            activity.finish (); c21/>}        system.exit (0);}    }

2. How to use

Add the following code to each activity's OnCreate method

Exitapputils.getinstance (). addactivity (this);

3. Achieve a full exit effect by pressing again

Define Time

Private long exittime = 0;

Exit the code and put it in the activity you want to exit.

public boolean onKeyDown (int keycode, keyevent event) {if (keycode = = Keyevent.keycode_back && event.getaction () = = Keyevent.action_down) {if ((System.currenttimemillis ()-exittime) >) {toastutils.show (getapplicationcontext (), r.string.exit_hint); exittime = System.currenttimemillis (); } else {exitapputils.getinstance (). exit ();//finish ();//system.exit (0);} return true; }return Super.onkeydown (KeyCode, event);}}
