Android controls the reality and hide of the soft keyboard

In Activity2 popped out soft keyboard, click Back, enter Activity1, inside also have edittext, such words soft keyboard still will show there, sometimes quite influence experience.

You can add such a method to the return event:

Private void Closesoftinput () {     = (Inputmethodmanager) Getsystemservice (context.input_method_service);     if (Imm.isactive ()) {        //  Toggle on/off status. tags can be replaced with         imm.togglesoftinput (inputmethodmanger.show_forced, Inputmethodmanager.hide_not_ always);    }  }
