At present, more and more apps require you to obtain SMS verification code when registering or performing corresponding operations. After clicking the button to obtain SMS verification code, a countdown appears, such as 120S. During the countdown period, the button background changes and a countdown occurs. When the countdown is over, if you do not obtain the verification code, you can click again.
The code looks like this:
VerCodeTimer mVerCodeTimer=(Button) findViewById(.login_get_ver_code);
private class VerCodeTimer extends CountDownTimer {
private int seconds;
private int interval;
//millisInFuture sets the total countdown time for you, for example, 60 seconds is set to 60,000 //countDownInterval sets the time interval for you, for example, it is usually 1 second, and customize it as needed. public VerCodeTimer(long millisInFuture, long countDownInterval) {
super(millisInFuture, countDownInterval);
seconds = (int) (millisInFuture / 1000);
interval= (int) (countDownInterval/1000);
}
//Actions done every time you specify the time interval @Override
public void onTick(long millisUntilFinished) {
((seconds-interval) + "Regain in seconds");
}
//Operation done at the end of the countdown↓↓ @Override
public void onFinish() {
(10);
("Reacquire verification code");
(true);
(.login_get_ver_code_before_bg);
}
}
@Override
public void onBackPressed() {
if (mVerCodeTimer != null)
();
();
}
When using:
(11); (false); (.login_get_ver_code_ago_bg); mVerCodeTimer = new VerCodeTimer(60000, 1000); ();
login_edit_normal_bg.xml：
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:andro
android:shape="rectangle"
android:useLevel="false">
<!-- Background fill color value -->
<solid android:color="#6c948b" />
<!-- radiusThe greater the value，More round -->

The above is the editor introducing all the codes for Android development that change the background of the button after obtaining the SMS verification code and the countdown appears. I hope this code can help you. Also, thank you for your support for my website.
