高仿android通讯录

最近都没有时间来更新我的博客，主要是在项目中遇到一些比较棘手的问题需要解决，今天我就把我解决的难题写了个Demo出来与大家一起分享，最终达到火种通讯录联系人界面的效果。
       在这次代码编写当中，我主要用到了WindowManager来显示友好提示

       在对数组进行排序的时候，我们可以用 Arrays.sort()方法轻松实现按字母顺序排序。

       另外在实现点击字母后让ListView滚动到以该字母开头的相应位置效果时，我们要用到如下方法：

       一个是通过public static int binarySearch(Object[] a,Object key) 方法来获得该字母出现的Item在ListView中的位置position，

       另一个就是 list.setSelection(localPosition); 来让List指向对应位置的Item。

       当你对这些方法都有所了解了以后，下面我们开始设计我们的Demo。

        我们先建立一个名为ContactsDemo的工程，然后就是代码部分了：

第一步，在res/layout的main.xml中我们来设置Activity中显示ListView上下层显示的效果，其实就是一个相对布局。

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<ListView  
 android:id="@+id/list"
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    />
<ListView
 android:id="@+id/listview" 
 android:layout_width="30dip"
 android:layout_height="wrap_content"
 android:layout_centerInParent="true"
 android:layout_alignParentTop="true"
 android:layout_alignParentRight="true"
 android:background="@null"
 />    
</RelativeLayout>

第二步，我们在layout中建一个list_popup_char_hint.xml，这是用来通过WindowManager显示友好提示的。

<?xml version="1.0" encoding="utf-8"?>  
<TextView xmlns:android="http://schemas.android.com/apk/res/android"  
    android:textSize="70sp"  
    android:textColor="#ffffffff"  
    android:minWidth="70dip"  
    android:maxWidth="70dip"  
    android:padding="10dip"  
    android:gravity="center"  
/>  

第三步，是list_item.xml用来设置ListView中Items的布局。

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:orientation="vertical"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent">
      <TextView android:id="@+id/text_first_char_hint"  
        android:layout_width="fill_parent"  
        android:layout_height="wrap_content"  
        android:textSize="20dip"  
        android:paddingLeft="10dip"  
        android:background="@drawable/background"
        android:visibility="gone">  
    </TextView>  
    <LinearLayout 
  android:orientation="horizontal"
  android:layout_width="fill_parent"
  android:layout_height="wrap_content">
  <TextView
   android:id="@+id/order"
   android:layout_width="wrap_content"
   android:layout_height="60dip"
   android:textSize="15dip"
   android:layout_gravity="left"
   android:layout_weight="2"/>
  <TextView
   android:id="@+id/content"
   android:gravity="center"
   android:layout_width="wrap_content"
   android:layout_height="60dip"
   android:textSize="15dip"
   android:layout_weight="2"/>
    </LinearLayout >
</LinearLayout >

第四步，是一个textview.xml用来显示右边覆盖在ListView上的ListView的Items

<?xml version="1.0" encoding="utf-8"?>
<TextView
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  android:textSize="20dip">
</TextView>

第五步，我们建一个名为ContactsDemo的类，然后就是实现功能的代码了，里面有非常详尽的注释，大家慢慢看吧。

import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.ListView;
import android.widget.TextView;
import android.widget.AbsListView.OnScrollListener;
