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

Android,方框,EditText,验证码

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

<?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

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/activity_main" android:layout_width="283dp" android:layout_height="273dp" android:layout_gravity="center" android:layout_marginBottom="50dp" android:background="@mipmap/bg_view1" android:orientation="vertical"> <include layout="@layout/layout_titile" /> <com.example.admin.myapplication.SecurityCodeView  android:id="@+id/scv_edittext"  android:layout_width="match_parent"  android:layout_height="wrap_content"  android:layout_gravity="center_horizontal"  android:layout_marginLeft="20dp"  android:layout_marginRight="20dp"  android:layout_marginTop="35dp" /> <TextView  android:id="@+id/tv_text"  android:layout_width="match_parent"  android:layout_height="wrap_content"  android:layout_marginLeft="20dp"  android:layout_marginRight="20dp"  android:layout_marginTop="13dp"  android:text="输入验证码表示同意《用户协议》" /> <LinearLayout  android:layout_width="match_parent"  android:layout_height="wrap_content"  android:layout_marginBottom="25dp"  android:layout_marginTop="3dp"  android:orientation="horizontal">  <TextView   android:id="@+id/tv_phone"   android:layout_width="0dp"   android:layout_height="wrap_content"   android:layout_marginLeft="20dp"   android:layout_marginRight="20dp"   android:layout_marginTop="13dp"   android:layout_weight="1"   android:text="电话" />  <TextView   android:id="@+id/tv_click"   android:layout_width="wrap_content"   android:layout_height="wrap_content"   android:layout_marginLeft="20dp"   android:layout_marginRight="20dp"   android:layout_marginTop="13dp"   android:text="重新发送"   android:textColor="@color/colorPrimary" /> </LinearLayout></LinearLayout>

[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;

 tv_click = (TextView) view.findViewById(R.id.tv_click);  editText.setInputCompleteListener(this);  tv_phone.setText(builder.getTextTitle());  img_close.setOnClickListener(new View.OnClickListener() {   @Override   public void onClick(View view) {    dismiss();   }  });  tv_click.setOnClickListener(new View.OnClickListener() {   @Override   public void onClick(View view) {    CountDownTimerUtils mCountDownTimerUtils = new CountDownTimerUtils(tv_click, 60000, 1000);    mCountDownTimerUtils.start();   }  }); } public static class Builder implements Serializable {  private String positiveButtonText;  private String negativeButtonText;  private String textTitle;  private String body;
