Android自定義方框EditText注冊(cè)驗(yàn)證碼

 更新時(shí)間：2018年06月05日 11:02:20   作者：Xia_焱  
這篇文章主要為大家詳細(xì)介紹了Android自定義方框EditText注冊(cè)驗(yàn)證碼，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

先來(lái)個(gè)效果圖讓大家看一看，現(xiàn)在好多app都用類(lèi)似的注冊(cè)頁(yè)

這里寫(xiě)圖片描述

實(shí)現(xiàn)思路

  • 用一個(gè)透明的EditText與四個(gè)TextView重疊，并給TextView設(shè)置默認(rèn)背景
  • 第4個(gè)TextView輸入完成后,要設(shè)置回調(diào),并且要加入增加刪除的回調(diào)
  • 還要監(jiān)聽(tīng)EditText內(nèi)容的變化,獲取內(nèi)容,并且改變EditText下面的TextView的顏色
  • 重新發(fā)送的是采用一個(gè)自定義的CountDownTimer類(lèi)
  • 彈出效果自定義的一個(gè)Dialog繼承DialogFragment

自定義EditText的布局

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="match_parent"
 android:layout_height="wrap_content">

 <LinearLayout
  android:layout_width="wrap_content"
  android:layout_height="47dp"
  android:gravity="center"
  android:orientation="horizontal"
  android:weightSum="3">


  <TextView
   android:id="@+id/item_code_iv1"
   style="@style/text_editStyle" />

  <View
   android:layout_width="0dp"
   android:layout_height="wrap_content"
   android:layout_weight="1" />

  <TextView
   android:id="@+id/item_code_iv2"
   style="@style/text_editStyle" />

  <View
   android:layout_width="0dp"
   android:layout_height="wrap_content"
   android:layout_weight="1" />

  <TextView
   android:id="@+id/item_code_iv3"
   style="@style/text_editStyle" />

  <View
   android:layout_width="0dp"
   android:layout_height="wrap_content"
   android:layout_weight="1" />

  <TextView
   android:id="@+id/item_code_iv4"
   style="@style/text_editStyle" />


 </LinearLayout>

 <EditText
  android:id="@+id/item_edittext"
  android:layout_width="match_parent"
  android:layout_height="47dp"
  android:background="@android:color/transparent"
  android:inputType="number" />
</RelativeLayout>

style

 <style name="text_editStyle" >
  <item name="android:layout_height">47dp</item>
  <item name="android:layout_width">47dp</item>
  <item name="android:background">@mipmap/bg_verify</item>
  <item name="android:gravity">center</item>
  <item name="android:textColor">@color/common_blue_0090FF</item>
  <item name="android:textSize">18sp</item>

</style>

View的代碼

private EditText editText;
 private TextView[] TextViews;
 private StringBuffer stringBuffer = new StringBuffer();
 private int count = 4;
 private String inputContent;

 public SecurityCodeView(Context context) {
  this(context, null);
 }

 public SecurityCodeView(Context context, AttributeSet attrs) {
  this(context, attrs, 0);
 }

 public SecurityCodeView(Context context, AttributeSet attrs, int defStyleAttr) {
  super(context, attrs, defStyleAttr);
  TextViews = new TextView[4];
  View.inflate(context, R.layout.view_security_code, this);

  editText = (EditText) findViewById(R.id.item_edittext);
  TextViews[0] = (TextView) findViewById(R.id.item_code_iv1);
  TextViews[1] = (TextView) findViewById(R.id.item_code_iv2);
  TextViews[2] = (TextView) findViewById(R.id.item_code_iv3);
  TextViews[3] = (TextView) findViewById(R.id.item_code_iv4);

  editText.setCursorVisible(false);//將光標(biāo)隱藏
  setListener();
 }

 /**
  * 清空輸入內(nèi)容
  */
 public void clearEditText() {
  stringBuffer.delete(0, stringBuffer.length());
  inputContent = stringBuffer.toString();
  for (int i = 0; i < TextViews.length; i++) {
   TextViews[i].setText("");
   TextViews[i].setBackgroundResource(R.mipmap.bg_verify);
  }
 }

 private InputCompleteListener inputCompleteListener;

 public void setInputCompleteListener(InputCompleteListener inputCompleteListener) {
  this.inputCompleteListener = inputCompleteListener;
 }

 public interface InputCompleteListener {
  void inputComplete();

  void deleteContent(boolean isDelete);
 }

 /**
  * 獲取輸入文本
  *
  * @return
  */
 public String getEditContent() {
  return inputContent;
}

監(jiān)聽(tīng)代碼

 private void setListener() {
  editText.addTextChangedListener(new TextWatcher() {

   @Override
   public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {

   }

   @Override
   public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {

   }

   @Override
   public void afterTextChanged(Editable editable) {
    //重點(diǎn) 如果字符不為""時(shí)才進(jìn)行操作
    if (!editable.toString().equals("")) {
     if (stringBuffer.length() > 3) {
      //當(dāng)文本長(zhǎng)度大于3位時(shí)edittext置空
      editText.setText("");
      return;
     } else {
      //將文字添加到StringBuffer中
      stringBuffer.append(editable);
      editText.setText("");//添加后將EditText置空 造成沒(méi)有文字輸入的錯(cuò)局
      // Log.e("TAG", "afterTextChanged: stringBuffer is " + stringBuffer);
      count = stringBuffer.length();//記錄stringbuffer的長(zhǎng)度
      inputContent = stringBuffer.toString();
      if (stringBuffer.length() == 4) {
       //文字長(zhǎng)度位4 則調(diào)用完成輸入的監(jiān)聽(tīng)
       if (inputCompleteListener != null) {
        inputCompleteListener.inputComplete();
       }
      }
     }

     for (int i = 0; i < stringBuffer.length(); i++) {
      TextViews[i].setText(String.valueOf(inputContent.charAt(i)));
      TextViews[i].setBackgroundResource(R.mipmap.bg_verify_press);
     }

    }
   }
  });

  editText.setOnKeyListener(new OnKeyListener() {
   @Override
   public boolean onKey(View v, int keyCode, KeyEvent event) {
    if (keyCode == KeyEvent.KEYCODE_DEL
      && event.getAction() == KeyEvent.ACTION_DOWN) {
     if (onKeyDelete()) return true;
     return true;
    }
    return false;
   }
  });
 }


 public boolean onKeyDelete() {
  if (count == 0) {
   count = 4;
   return true;
  }
  if (stringBuffer.length() > 0) {
   //刪除相應(yīng)位置的字符
   stringBuffer.delete((count - 1), count);
   count--;
   // Log.e(TAG, "afterTextChanged: stringBuffer is " + stringBuffer);
   inputContent = stringBuffer.toString();
   TextViews[stringBuffer.length()].setText("");
   TextViews[stringBuffer.length()].setBackgroundResource(R.mipmap.bg_verify);
   if (inputCompleteListener != null)
    inputCompleteListener.deleteContent(true);//有刪除就通知manger

  }
  return false;
 }

自定義的EditText到這了算是結(jié)束了

彈出框的布局

[大體的思路,點(diǎn)擊事件之后彈出一個(gè)Dialog,然后再這個(gè)頁(yè)面進(jìn)行注冊(cè),有可能這個(gè)Dialog會(huì)復(fù)用,或者改一些樣式(采用Builder設(shè)計(jì)模式)]
