 public CountDownTimerUtils(TextView textView, long millisInFuture, long countDownInterval) {
   super(millisInFuture, countDownInterval);
   this.mTextView = textView;
 }

@Override
 public void onTick(long millisUntilFinished) {
   mTextView.setClickable(false); //设置不可点击
   mTextView.setText(millisUntilFinished / 1000 + "秒后可重新发送"); //设置倒计时时间
   mTextView.setBackgroundResource(R.drawable.bg_identify_code_press); //设置按钮为灰
   SpannableString spannableString = new SpannableString(mTextView.getText().toString());
   ForegroundColorSpan span = new ForegroundColorSpan(Color.RED);
   spannableString.setSpan(span, 0, 2, Spannable.SPAN_INCLUSIVE_EXCLUSIVE);
   mTextView.setText(spannableString);
 }

@Override
 public void onFinish() {
   mTextView.setText("重新获取验证码");
   mTextView.setClickable(true);//重新获得点击
   mTextView.setBackgroundResource(R.drawable.bg_identify_code_normal);
 }
}

   tv_yzm.setOnClickListener(new View.OnClickListener() {
     @Override
     public void onClick(View v) {
       CountDownTimerUtils mCountDownTimerUtils = new CountDownTimerUtils(tv_yzm, 60000, 1000);
       mCountDownTimerUtils.start();
     }
   });
 }
