A simple package for Android to get the verification code countdown 60 seconds button

Since it is often troublesome to need a countdown button when registering for a verification code, take some time to write a Timebutton

The key mouse characteristics,

Timebutton use the same time as the normal button without conflict,

Timebutton back in the countdown, and if there's not more time left to go, it'll keep running.

Timebutton inside the button click Display and Countdown logic,

Timebutton will be destroyed after the activity is destroyed, and will not run in the background like a thread.

Timebutton display text and countdown can be set on their own, of course, there are default,

To post the code, you first need to define a map in application

public class App extends application {//For holding countdown time public static map<string, long> Map;}

And then use it in the activity

Package Com.yung.timebutton;import Android.app.activity;import Android.os.bundle;import android.view.View;import         Android.view.view.onclicklistener;import android.widget.toast;/** * Test Main interface * * @author yung * <P> * January 14, 2015 13:00:26 */public class Mainactivity extends Activity implements Onclicklistener {private Timebutton V; @Overri deprotected void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate); Setcontentview ( R.layout.activity_main); v = (Timebutton) Findviewbyid (R.id.button1); v.oncreate (savedinstancestate); v.setTextAfter ("Regain after Seconds"). Settextbefore ("Click to get Verification Code"). Setlenght (*); V.setonclicklistener (this);} @Overridepublic void OnClick (View v) {//TODO auto-generated method Stubtoast.maketext (Mainactivity.this, " This is the process caller Onclicklistnenr ", Toast.length_short). Show (); @Overrideprotected void OnDestroy () {//TODO auto-generated method Stubv.ondestroy (); Super.ondestroy ();}}

The next step is Timebutton's code.
