使用CountDownTimer实现倒计时功能

// 倒计时60s
new CountDownTimer(60000, 1000) {

@Override
public void onTick(long millisUntilFinished) {
mReGetAuthCodeButton
.setText(getString(R.string.tip_get_code_time,
millisUntilFinished / 1000));

}

@Override
public void onFinish() {
mBackAble = true;
mReGetAuthCodeButton
.setBackgroundResource(R.drawable.blue_button_selector);
mReGetAuthCodeButton.setText(R.string.re_get_code);
}
}.start();
