1：新建一个Android项目将相关资源文件拷贝到如图所示文件夹中

2：在activity_main.xml布局文件中资源文件布局如下

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >

    <EditText 
        android:id="@+id/et_test"
        android:layout_width="180dip"
        android:layout_height="wrap_content"
        android:hint="请输入QQ号码"
        />
   <ImageButton 
       android:id="@+id/ib_test"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:background="@drawable/button"
       android:layout_alignTop="@id/et_test"
       android:layout_alignRight="@id/et_test"
       android:layout_alignBottom="@id/et_test"
       />
</RelativeLayout>

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="40dip"
    android:orientation="horizontal"
    android:gravity="center_horizontal"
     >
    <ImageView 
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"
        android:src="@drawable/user"
        />
       <TextView 
        android:id="@+id/tv_test"
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"
        android:layout_weight="1"
        />
       <ImageView 
           android:id="@+id/ib_test1"
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"
        android:src="@drawable/delete"
        />
</LinearLayout>

PopupWindow在Editext中使用
