This article for everyone to share the Android landing interface to clear the contents of the input box and vibration effect of all the code, the details are as follows:

The main code is as follows

A custom edittext that displays a clear button when text is available:

Import Android.content.Context;
Import android.graphics.drawable.Drawable;
Import android.text.Editable;
Import Android.text.TextWatcher;
Import Android.util.AttributeSet;
Import android.view.MotionEvent;
Import Android.view.View;
Import android.view.animation.Animation;
Import Android.view.animation.CycleInterpolator;
Import android.view.animation.TranslateAnimation;

Import Android.widget.EditText; public class Clearedittext extends EditText implements view.onfocuschangelistener,textwatcher{//delete button reference private Dra

  Wable mcleardrawable;

  Control has focus private Boolean hasfoucs;
  Public Clearedittext {This (context, NULL); "Public clearedittext" (context context, AttributeSet attrs) {//It is also important to construct the method, without which many attributes cannot be defined in the XML. TRS, Android.
  R.attr.edittextstyle);
    Public Clearedittext (context, AttributeSet attrs, int defstyle) {Super (context, attrs, Defstyle);
  Init (); private void Init () {//Get edittext DRAWableright, if there is no setting we will use the default picture mcleardrawable = Getcompounddrawables () [2];
        if (mcleardrawable = = null) {//throw new NullPointerException ("You can add drawableright attributes in XML");
      mcleardrawable = Getresources (). getdrawable (R.drawable.selector_ic_delete); //getintrinsicwidth () Gets the drawable width on the phone, so the values obtained at different resolutions are different, and the key location mcleardrawable.setbounds (0, 0, Mcleardrawa

      Ble.getintrinsicwidth (), Mcleardrawable.getintrinsicheight ());
      The default setting hides the icon setcleariconvisible (false);
      Set focus-Changing listening setonfocuschangelistener (this);
    Set the input box to change the content of the listening addtextchangedlistener (this);
     /** * Because we can not set the Click event directly to EditText, so we use to remember the position we pressed to simulate the click event * when we press the position at the edittext width-the icon to the right of the control spacing-the width of the icon and 
      * EditText Width-The distance between the icon and the right side of the control if we click on the icon, the vertical direction is not considered * * @Override public boolean ontouchevent (Motionevent event) { if (event.getaction () = = motionevent.action_up) {if (Getcompounddrawables () [2]!= null) {

          TX () < ((GetWidth ()-getpaddingright ()));
          if (touchable) {This.settext ("");
    }} return Super.ontouchevent (event); /** * When Clearedittext focus changes, judge inside string length set clear icon display and hide */@Override public void Onfocuschange (View V
      , Boolean hasfocus) {this.hasfoucs = Hasfocus;
      if (hasfocus) {setcleariconvisible (GetText (). Length () > 0);
      else {setcleariconvisible (false);  }/** * Set clear icon display and hide, call setcompounddrawables for EditText draw up * @param visible/protected void
      Setcleariconvisible (Boolean visible) {drawable right = visible? Mcleardrawable:null;
    Setcompounddrawables (Getcompounddrawables () [0], Getcompounddrawables () [1], right, Getcompounddrawables () [3]); /** * The method of callback when the contents of the input box are changed
     * * @Override public void ontextchanged (charsequence s, int start, int count,int after) {if (Hasfoucs) {

      Translateanimation.setinterpolator (New Cycleinterpolator (counts));
      Translateanimation.setduration (1000);
    return translateanimation;
 }
}

Mainactivity.java is mainly a pop-up word to indicate the click of the button event

Import Android.os.Bundle;
Import Android.view.View;
Import Android.widget.Button;
Import Android.widget.Toast;
Import android.app.Activity;

public class Mainactivity extends activity {

  private Button btnlogin;

  @Override
  protected void onCreate (Bundle savedinstancestate) {
    super.oncreate (savedinstancestate);
    Setcontentview (r.layout.activity_login);
    Btnlogin = (Button) This.findviewbyid (r.id.btnlogin);
  }

  public void Login (view view) {
    Toast.maketext (this, "Landing", Toast.length_long). Show ();

  }

The layout files are as follows:

<?xml version= "1.0" encoding= "Utf-8"?> <linearlayout xmlns:android= "http://schemas.android.com/apk/res/" Android "Android:layout_width=" Fill_parent "android:layout_height=" fill_parent "android:background=" #ffffffff "and roid:orientation= "vertical" android:padding= "4.0dip" > <com.xuliugen.clearedittext.clearedittext android:id = "@+id/etxtemail" style= "@style/edittext" android:layout_width= "fill_parent" android:layout_height= "Wrap_conte NT "android:layout_margintop=" 30.0dip "android:drawableleft=" "@drawable/icon_reg_name" android:drawablepadding=

 ick= "Login" android:text= "Landing"/> </LinearLayout>

In addition, there are some selector files, picture resources, etc.:
Bg_btn_style_green.xml

<?xml version= "1.0" encoding= "Utf-8"?> <selector xmlns:android=
"http://schemas.android.com/apk/res/" Android ">

  <item android:state_enabled=" false "><shape android:shape=" Rectangle ">
      < Corners android:radius= "2.0dip"/>

      <solid android:color= "@color/green_btn_color_disable"/>
    </ shape></item>
  <item android:state_pressed= "true" ><shape android:shape= "Rectangle" >
      <corners android:radius= "2.0dip"/>

      <solid android:color= "@color/green_btn_color_pressed"/>
    </shape></item>
  <item><shape android:shape= "Rectangle" >
      <corners android: radius= "2.0dip"/>

      <solid android:color= "@color/green_btn_color_normal"/>
    </shape></ Item>

</selector>

Bg_edittext_selector.xml

<?xml version= "1.0" encoding= "Utf-8"?> <selector xmlns:android=
"http://schemas.android.com/apk/res/" Android >

  <item android:drawable= "@drawable/input_bar_bg_active" android:state_focused= "true"/>
  <item android:drawable= "@drawable/input_bar_bg_normal"/>

</selector>
