Android Prevent button Multiple Click Summary

    Long Lastclick;    public void OnClick (View v) {          ///greater than one second square through          if (System.currenttimemillis ()-Lastclick <=)          {              Showtoast ("What's the point!!!");              return;          }          Lastclick = System.currenttimemillis ();      }  

A common way of writing, recording the time of the two click events before and after, and then judging whether a difference is within a given limittime, if it is not clicked,

Otherwise, you can click.

This way has shortcomings, multiple button, fast switch click, the control effect is not very good, so I try to use the Android handler to control button click event.

//new            A Handler for message processing Handler Handler = new Handler () {@Override public void handlemessage (message msg) {            Super.handlemessage (msg);            if (msg.what = = Goto_dialog) {//Call button click event Handling Method Gotodialog Gotodialog ((Integer) msg.obj); }        }    };       Clears the message handler.removemessages (Goto_dialog) before @Override public void OnClick (View v) {//handler message is sent;        Binds a msg, which is the ID of the button to be needed next, Message msg = Message.obtain ();        Msg.what = Goto_dialog;        Msg.obj = V.getid ();    Send Message interval 1 sec handler.sendmessagedelayed (msg, 1000); } private void Gotodialog (int id) {//multiple botton switch (ID) {case r.id.btn_back:.           ... break;      Case R.id.btn_sumbit: ... break; }

With the above handler processing, you no longer have to worry about switching between multiple buttons.

Note: Remember to destroy the handler after you run out of
