Use a broadcast to exit a program that has multiple activity open

Create a new parent class, dynamically register the broadcast in the parent class, end the current activity in this broadcast's Onrecive method, let each activity inherit the parent class, send the broadcast in the activity to be closed, fix

Here is the code

Parent class

protectedmyrecive myrecive; Private classMyreciveextendsbroadcastreceiver{@Override Public voidOnReceive (Context context, Intent Intent) {LOG.V ("SK", Getlocalclassname ());        Finish (); }} @Overrideprotected voidonCreate (Bundle savedinstancestate) {Super. OnCreate (savedinstancestate);        Setcontentview (R.LAYOUT.ACTIVITY_MAIN_ACTIVITY4); Myrecive=Newmyrecive (); Intentfilter _filter=NewIntentfilter (); _filter.addaction ("Com.xl.u323");    Registerreceiver (Myrecive,_filter); }

End method

     Public void OnClick (View v) {                new  Intent ();                _intent.setaction ("com.xl.u323");                Sendbroadcast (_intent);}
