Android自定义方框EditText注册验证码

先来个效果图让大家看一看，现在好多app都用类似的注册页

实现思路

• 用一个透明的EditText与四个TextView重叠，并给TextView设置默认背景
• 第4个TextView输入完成后,要设置回调,并且要加入增加删除的回调
• 还要监听EditText内容的变化,获取内容,并且改变EditText下面的TextView的颜色
• 重新发送的是采用一个自定义的CountDownTimer类
• 弹出效果自定义的一个Dialog继承DialogFragment

自定义EditText的布局

style

View的代码

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);//将光标隐藏
  setListener();
 }

 /**
  * 清空输入内容
  */
 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);
 }

 /**
  * 获取输入文本
  *
  * @return
  */
 public String getEditContent() {
  return inputContent;
}

监听代码

 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) {
    //重点 如果字符不为""时才进行操作
    if (!editable.toString().equals("")) {
     if (stringBuffer.length() > 3) {
      //当文本长度大于3位时edittext置空
      editText.setText("");
      return;
     } else {
      //将文字添加到StringBuffer中
      stringBuffer.append(editable);
      editText.setText("");//添加后将EditText置空 造成没有文字输入的错局
      // Log.e("TAG", "afterTextChanged: stringBuffer is " + stringBuffer);
      count = stringBuffer.length();//记录stringbuffer的长度
      inputContent = stringBuffer.toString();
      if (stringBuffer.length() == 4) {
       //文字长度位4 则调用完成输入的监听
       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) {
   //删除相应位置的字符
   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);//有删除就通知manger

  }
  return false;
 }

自定义的EditText到这了算是结束了

弹出框的布局

[大体的思路,点击事件之后弹出一个Dialog,然后再这个页面进行注册,有可能这个Dialog会复用,或者改一些样式(采用Builder设计模式)]

接下来自定义Dialog

要实现EditText的两个接口

public class XyAlertDialog extends DialogFragment implements SecurityCodeView.InputCompleteListener {
 private SecurityCodeView editText;
 private TextView text;
 private TextView tv_title;
 private ImageView img_close;
 public static final String TAG = XyAlertDialog.class.getSimpleName();
 private Builder builder;
 private static XyAlertDialog instance = new XyAlertDialog();
 private TextView tv_phone;
 private TextView tv_click;

 public static XyAlertDialog getInstance() {
  return instance;
 }

 @Override
 public void onCreate(@Nullable Bundle savedInstanceState) {
  this.setCancelable(true);
  setRetainInstance(true);
  super.onCreate(savedInstanceState);

  if (savedInstanceState != null) {
   try {
    if (isAdded() && getActivity() != null)
     if (builder != null)
      builder = (Builder) savedInstanceState.getSerializable(Builder.class.getSimpleName());
   } catch (Exception e) {
   }

  }
 }

 @Override
 public void onSaveInstanceState(Bundle outState) {
  super.onSaveInstanceState(outState);
  try {
   if (isAdded() && getActivity() != null)
    if (builder != null)
     outState.putSerializable(Builder.class.getSimpleName(), builder);
  } catch (Exception e) {
   Log.d(TAG, e.toString());
  }
 }

 @NonNull
 @Override
 public Dialog onCreateDialog(Bundle savedInstanceState) {
  Dialog dialog = super.onCreateDialog(savedInstanceState);
  dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
  dialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE);
  dialog.setCanceledOnTouchOutside(false);//点击旁白不消失
  return dialog;
 }

 @Nullable
 @Override
 public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup
   container, @Nullable Bundle savedInstanceState) {
  return inflater.inflate(R.layout.activity_xia, container, false);
 }

 @Override
 public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
  super.onViewCreated(view, savedInstanceState);
  initViews(view);

 }

 private Dialog show(Activity activity, Builder builder) {
  this.builder = builder;
  if (!isAdded())
   show(((AppCompatActivity) activity).getSupportFragmentManager(), TAG);
  return getDialog();
 }

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