Android带清除按钮、密码可见小眼睛的输入框

前言

相信不少小伙伴在开发登录功能时候，或多或少都会用到输入框清除按钮、密码可见与隐藏小眼睛按钮，我之前也是但写这个功能，但是在找回密码、忘记密码里面还要重新写一次很是麻烦，现在我把它只做了一个自定义控件，可以配置清除按钮、密码可见小眼睛是否显示以及图标，有渐隐渐显和横向移动动画，不知道怎么上传可以直接观看的视频，附上三张效果图，可以点击链接观看视频是否是你想要的效果。

 

一、自定义控件clearedittext

我的这个自带清除、小眼睛的控件，是一个自定义控件，控件名称clearedittext.class，继承relativelayout并有布局引用。在拷贝到项目里面后，使用时候只需要与普通输入框控件一样，进行相关的配置即可，部分属性需要使用自定义属性，具体见代码。

二、使用步骤

 1.拷贝clearedittext.class

拷贝clearedittext.class类到自己的项目里，再考拷贝它相关的布局文件、自定义属性、默认图片即可，下面贴出clearedittext主要代码：

public class clearedittext extends relativelayout {
 private imageview ivlefticon;
 private edittext myedie;
 private imageview iveditclean;
 private imageview ivediteye;
 private boolean ischecked = true;
 private context mcontext;
 private typedarray mtypedarray;
 private boolean showclean = true;//清空图标是否显示，true:显示
 private boolean showeye = false;//密码可见图标是否显示，true:显示
 private int drawableleft = -1;//是否显示输入框左侧图片
 private int drawableeyeopen = r.drawable.clear_icon_eye_open;//可以看见密码小眼睛样式
 private int drawableeyeclose = r.drawable.clear_icon_eye_close;//不可见密码小眼睛样式
 private int drawableclean = r.drawable.clear_icon_close;//清除按钮图片
 private int cleanpadding = 0;//清除按钮padding边距
 private string hintstr;
 private string textstr;
 private int mtextcolorhint = color.black;
 private int mtextcolor = color.black;
 private int mtextsize = -1;
 private int mmaxlength = 2000;
 private int mmaxlines = 1;
 private int minputtype = 0;//输入类型，就做了不限制、数字、文本密码三种
 private boolean isinput = false;//输入1个字符后更改状态为true,保证小眼睛移动一次
 private boolean ishideclean = false;//输入字符后，清除了需要小眼睛归为，清除按钮隐藏
 private int ivwidth = 45;//关闭按钮的宽度

 public clearedittext(context context) {
  super(context);
  mcontext = context;
  initview();
 }

 public clearedittext(context context, attributeset attrs, int defstyle) {
  super(context, attrs, defstyle);
  mcontext = context;
  mtypedarray = mcontext.obtainstyledattributes(attrs, r.styleable.myedittext);
  initview();
 }

 public clearedittext(context context, attributeset attrs) {
  super(context, attrs);
  mcontext = context;
  mtypedarray = mcontext.obtainstyledattributes(attrs, r.styleable.myedittext);
  showclean = mtypedarray.getboolean(r.styleable.myedittext_showclean, showclean);
  drawableclean = mtypedarray.getresourceid(r.styleable.myedittext_drawableclean, drawableclean);
  cleanpadding = mtypedarray.getdimensionpixelsize(r.styleable.myedittext_cleanpadding, cleanpadding);

  showeye = mtypedarray.getboolean(r.styleable.myedittext_showeye, showeye);
  drawableleft = mtypedarray.getresourceid(r.styleable.myedittext_drawableleft, -1);
  drawableeyeclose = mtypedarray.getresourceid(r.styleable.myedittext_drawableeyeclose, drawableeyeclose);
  drawableeyeopen = mtypedarray.getresourceid(r.styleable.myedittext_drawableeyeopen, drawableeyeopen);

  hintstr = mtypedarray.getstring(r.styleable.myedittext_hint);
  textstr = mtypedarray.getstring(r.styleable.myedittext_text);
  mtextcolorhint = mtypedarray.getcolor(r.styleable.myedittext_textcolorhint, mtextcolorhint);
  mtextcolor = mtypedarray.getcolor(r.styleable.myedittext_textcolor, mtextcolor);
  mtextsize = mtypedarray.getdimensionpixelsize(r.styleable.myedittext_textsize, mtextsize);
  mmaxlength = mtypedarray.getinteger(r.styleable.myedittext_maxlength, mmaxlength);
  mmaxlines = mtypedarray.getdimensionpixelsize(r.styleable.myedittext_maxlines, mmaxlines);
  minputtype = mtypedarray.getinteger(r.styleable.myedittext_inputtype, minputtype);

  mtypedarray.recycle();
  initview();
 }

 // 初始化视图
 private void initview() {
  view view = view.inflate(getcontext(), r.layout.clear_layout_view, null);
  ivlefticon = (imageview) view.findviewbyid(r.id.iv_edit_left_icon);

  myedie.settextcolor(mtextcolor);
  myedie.setmaxlines(mmaxlines);
  myedie.setfilters(new inputfilter[]{new inputfilter.lengthfilter(mmaxlength)});
  if (mtextsize != -1) {
   myedie.settextsize(typedvalue.complex_unit_px, mtextsize);
  } else {
   myedie.settextsize(15);
  }
  if (minputtype == 1) {
   myedie.setinputtype(inputtype.type_class_number);
  } else if (minputtype == 2) {

  }
  if (showeye) {
   myedie.settransformationmethod(new asteriskpasswordtransformationmethod());
  }
  if (showclean && showeye) {
   int left = myedie.getpaddingleft();
   int top = myedie.getpaddingtop();
   int bottom = myedie.getpaddingbottom();
   myedie.setpadding(left, top, utils.dp2px(mcontext, 90), bottom);
  } else if (!showclean && !showeye) {
   int left = myedie.getpaddingleft();
   int top = myedie.getpaddingtop();
   int right = myedie.getpaddingright();
   int bottom = myedie.getpaddingbottom();
   myedie.setpadding(left, top, right, bottom);

   int top = myedie.getpaddingtop();
   int bottom = myedie.getpaddingbottom();
   myedie.setpadding(left, top, utils.dp2px(mcontext, 45), bottom);
  }
  
  myedie.addtextchangedlistener(new textwatcher() {
   @override
   public void beforetextchanged(charsequence s, int start, int count, int after) {

   }

   @override
   public void ontextchanged(charsequence s, int start, int before, int count) {
    if (s.length() > 0) {
     ishideclean = false;
    }
   }

   @override
   public void aftertextchanged(editable s) {
    if (s.length() > 0 && !isinput) {//输入字符大于0且只有一个字符时候显示清除按钮动画，小眼睛移动出位置给清除按钮使用
     showeditclean();
     moveediteye();
     isinput = true;
    } else if (s.length() == 0) {//无字符小眼睛归位
     undoediteye();
    }
    if (s.length() == 0 & !ishideclean) {
     hideeditclean();
     ishideclean = true;
     isinput = false;
    }
    if (oneditinputlistener != null) {
     oneditinputlistener.input(gettext());
    }
   }
  });

  seteditclean(showclean);
  iveditclean.setonclicklistener(new onclicklistener() {
   @override
   public void onclick(view v) {
    myedie.settext("");
   }
  });
  iveditclean.setimageresource(drawableclean);
  iveditclean.setpadding(cleanpadding, cleanpadding, cleanpadding, cleanpadding);

  setediteye(showeye);
  ivediteye.setonclicklistener(new onclicklistener() {
   @override

    if (ischecked) {
     // 输入一个对用户可见的密码
     myedie.settransformationmethod(hidereturnstransformationmethod.getinstance());
     myedie.setselection(gettext().length());
     ivediteye.setimageresource(drawableeyeopen);
     ischecked = false;
    } else {
     // 输入一个对用户不可见的密码
     myedie.settransformationmethod(new asteriskpasswordtransformationmethod());
     myedie.setselection(gettext().length());
     ivediteye.setimageresource(drawableeyeclose);
     ischecked = true;
    }
   }
  });
  if (drawableleft != -1) {
   ivlefticon.setvisibility(view.visible);
   ivlefticon.setimageresource(drawableleft);
  } else {
   ivlefticon.setvisibility(view.gone);
  }
  view.setlayoutparams(new layoutparams(viewpager.layoutparams.match_parent, viewpager.layoutparams.wrap_content));
  addview(view);
 }

 //密码不可见时候，使用*替换密码
 public class asteriskpasswordtransformationmethod extends passwordtransformationmethod {
  @override
  public charsequence gettransformation(charsequence source, view view) {
   return new passwordcharsequence(source);
  }

  private class passwordcharsequence implements charsequence {

   private charsequence msource;

   public passwordcharsequence(charsequence source) {
    msource = source; // store char sequence
   }

   public char charat(int index) {
    return '*'; // this is the important part
   }

   public int length() {
    return msource.length(); // return default
   }

   public charsequence subsequence(int start, int end) {
    return msource.subsequence(start, end); // return default
   }
  }

 }

 public string gettext() {
  return myedie.gettext().tostring().trim();
 }

 public void settext(string text) {
  myedie.settext(text);
 }

 //代码设置是否显示清除按钮
 public void seteditclean(boolean iscanclose) {
  showclean = iscanclose;
 }

 //代码设置是否显示小眼睛
 public void setediteye(boolean iscansee) {
  showeye = iscansee;
  if (showeye == true) {
   ivediteye.setvisibility(view.visible);
  } else {

  }
 }

 private void showeditclean() {

 private void undoediteye() {

  }
 }

 public oneditinputlistener oneditinputlistener;

 public void setoneditinputlistener(oneditinputlistener listener) {
  oneditinputlistener = listener;
 }
 //输入监听
 public interface oneditinputlistener {
  void input(string content);
 }

}

2.使用示例

下面是在xml布局时候，如何使用clearedittext的示例，部分自定义属性使用xmlns:app="http://schemas.android.com/apk/res-auto"引用调用。app:showeye属性true-显示小眼睛，false-关闭小眼睛。

 <com.huaweixia.clear.clearedittext
  android:id="@+id/et_login_password"
  android:layout_width="0dp"
  android:layout_height="45dp"
  android:layout_margintop="30dp"
  android:background="@drawable/line_bg_white_only_bottom_d8"
  android:paddingleft="10dp"
  app:hint="请输入密码"
  app:layout_constraintleft_toleftof="@id/et_login_number"
  app:layout_constraintright_torightof="@id/et_login_number"
  app:layout_constrainttop_tobottomof="@id/et_login_number"
  app:showeye="true"
  app:textcolor="@color/tv_black_333333"
  app:textcolorhint="@color/tv_gray_999999"
  app:textsize="15sp" />

总结

一开始我之前自己用的自带清空、密码可见的自定义输入框，是没有清除按钮显示，密码可见按钮移动动效，清除按钮显示比较僵硬，在清除按钮隐藏时候小眼睛按钮后面有一定空白，显示看着比较别扭，加了动效后视觉上感觉更加顺畅，希望对部分需要的小伙伴有空，下面附上 下载demo的链接 地址，有需要可以下载看看。
