When Android realizes phone verification, the button countdown 60s

Mobile phone registration will generally have a button, the default display to obtain a verification code, click and then become xx seconds after re-obtain the verification code

On the internet there are two ways to do this, one is to customize a Timebutton, the other is to use the encapsulated 60 seconds to obtain the Code tool class

First, add a line of code to the App.java class first

 Public Static Map<string, long> map; // time to hold the countdown

The Timebutton class is then added to the project, and the time default is 60s, which can then be modified in the code by the set method.

Textafter =Text1; return  This; }    /*** Set the text before clicking*/     PublicTimebutton Settextbefore (String text0) { This. Textbefore =text0;  This. SetText (Textbefore); return  This; }    /*** Set to timing length * *@paramLenght * Time default milliseconds *@return     */     PublicTimebutton Setlenght (Longlenght) {         This. Lenght =lenght; return  This; }    /***/}

The use of Timebutton in a resource file is not much different from the button

<Net.zhomi.negotiation.view.utils.TimeButton//timebutton the package android:id= "@+id/btn_getcode"Android:layout_width= "0DP"Android:layout_height= "Match_parent"Android:layout_marginright= "15DP"Android:layout_weight= "2"Android:background= "@null"Android:singleline= "true"Android:text= "Re-fetch after 60 seconds"Android:textcolor= "@color/balck"android:textsize= "@dimen/normal_text_size" />

The second Kind

First look at the packaged tool class

 Packagecom.example.timebtn;ImportAndroid.os.CountDownTimer;ImportAndroid.widget.Button; Public classTimercountextendsCountdowntimer {PrivateButton BNT;  PublicTimercount (LongMillisinfuture,LongCountdowninterval, Button BNT) {        Super(Millisinfuture, countdowninterval);  This. BNT =BNT; }     PublicTimercount (LongMillisinfuture,Longcountdowninterval) {        Super(Millisinfuture, countdowninterval); //TODO auto-generated Constructor stub} @Override Public voidonfinish () {//TODO auto-generated Method StubBnt.setclickable (true); Bnt.settext ("Get Verification Code"); } @Override Public voidOnTick (Longarg0) {        //TODO auto-generated Method StubBnt.setclickable (false); Bnt.settext (arg0/1000 + "second after re-acquisition"); }}

How to use:

Button btn =new Timercount (60000,btn); Timer.start ();

It seems that the second type of code is simpler, but it is recommended to use the first.
