获取短信验证码之后按钮背景变化并且出现倒计时
Button getVerCodeButton = (Button) findViewById(R.id.login_get_ver_code);
private class VerCodeTimer extends CountDownTimer { private int seconds; private int interval; private int nowTime; //millisInFuture为你设置的此次倒计时的总时长,比如60秒就设置为60000 //countDownInterval为你设置的时间间隔,比如一般为1秒,根据需要自定义。 public VerCodeTimer(long millisInFuture, long countDownInterval) { super(millisInFuture, countDownInterval); seconds = (int) (millisInFuture / 1000); interval= (int) (countDownInterval/1000); nowTime=seconds; } //每过你规定的时间间隔做的操作 @Override public void onTick(long millisUntilFinished) { nowTime-=interval; getVerCodeButton.setText(nowTime + "秒后重新获取"); } //倒计时结束时做的操作↓↓ @Override public void onFinish() { getVerCodeButton.setTextSize(10); getVerCodeButton.setText("重新获取验证码"); getVerCodeButton.setClickable(true); getVerCodeButton.setBackgroundResource(R.drawable.login_get_ver_code_before_bg); } }
使用的时候:
getVerCodeButton.setTextSize(11); getVerCodeButton.setClickable(false); getVerCodeButton.setBackgroundResource(R.drawable.login_get_ver_code_ago_bg); mVerCodeTimer = new VerCodeTimer(10000, 1000); mVerCodeTimer.start();
