Simple encapsulation of the 60-second countdown Button for Android to get the verification code, Android button

Since it is troublesome to use a countdown button when registering to obtain the verification code, I wrote a TimeButton.

Mouse and mouse features,

TimeButton does not conflict with common buttons,

TimeButton returns the result in the countdown. If the time does not exceed the remaining time, it will continue to run,

In TimeButton, the button click display and countdown logic are completed,

The TimeButton will also be destroyed after the activity is destroyed and will not run in the background like a thread,

The display text and countdown of TimeButton can be set by yourself. Of course, the default value is also available,

To paste the code, you must first define a Map in the Application

Public class App extends Application {// used to store the countdown time public static Map <String, Long> map ;}

And then use

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; @ Overrideprotected void onCreate (Bundle savedInstanceState) {super. onCreate (savedInstanceState); setContentView (R. layout. activity_main); v = (TimeButton) findViewById (R. id. button1); v. onCreate (savedInstanceState); v. setTextAfter ("Get again in seconds "). setTextBefore ("click to obtain Verification Code "). setLenght (15*1000); v. setOnClickListener (this) ;}@ Overridepublic void onClick (View v) {// TODO Auto-generated method stubToast. makeText (MainActivity. this, "this is processing the caller onclicklistnenr", Toast. LENGTH_SHORT ). show () ;}@ Overrideprotected void onDestroy () {// TODO Auto-generated method stubv. onDestroy (); super. onDestroy ();}}

The following is the TimeButton code.

Package com. yung. timebutton; import java. util. hashMap; import java. util. map; import java. util. timer; import java. util. timerTask; import android. annotation. suppressLint; import android. content. context; import android. OS. bundle; import android.

I wrote a *** @ author yung * <P> * January 14, 2015 [Buddha bless never had a BUG] * <p> * PS: since it is found that the schedule method cannot be re-executed after each timer cancle (), it is only possible that the timer is completed. * re-set timer every time you start timing.
