這篇文章主要為大家詳細(xì)介紹了Android點(diǎn)擊獲取驗(yàn)證碼60秒后重新獲取驗(yàn)證碼的方法，具有一定的參考價值，感興趣的小伙伴們可以參考一下

本文實(shí)例為大家分享了Android實(shí)現(xiàn)點(diǎn)擊獲取驗(yàn)證碼60秒后重新獲取的具體代碼，供大家參考，具體內(nèi)容如下

  }

  @Override
  public void onTick(long millisUntilFinished) {
    mTextView.setClickable(false); //設(shè)置不可點(diǎn)擊
    mTextView.setText(millisUntilFinished / 1000 + "秒后可重新發(fā)送"); //設(shè)置倒計(jì)時時間
    mTextView.setBackgroundResource(R.drawable.bg_identify_code_press); //設(shè)置按鈕為灰
    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("重新獲取驗(yàn)證碼");
    mTextView.setClickable(true);//重新獲得點(diǎn)擊
    mTextView.setBackgroundResource(R.drawable.bg_identify_code_normal);
  }
}

TextView背景色

bg_identify_code_press

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
  <solid android:color="#C0C0C0" /> <!--填充色 透明-->
  <corners android:radius="7dp" /> <!-- 圓角 -->
</shape>

bg_identify_code_normal

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
  <solid android:color="#2BAF2B" /> <!--填充色 透明-->
  <corners android:radius="7dp" /> <!-- 圓角 -->
</shape>

布局代碼

 <TextView
    android:id="@+id/tv_yzm"
    android:layout_width="match_parent"
    android:layout_marginTop="50dp"
    android:layout_height="45dp"
    android:background="@drawable/bg_identify_code_normal"
    android:gravity="center"
    android:text="點(diǎn)擊獲取驗(yàn)證碼"
    android:textColor="#FFF"
    android:textSize="15dp" />

項(xiàng)目代碼

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