android通讯录开发（粗糙实现微信通讯录的功能）

主要实现功能：

一、实现名单的中英文混合排序，按照联系人名单的首字母进行分类。

二、实现右侧的字母导航功能，根据字母定位相应的名单组，方便查找。

三、实现搜索功能（1）输入字母进行搜索时，按照精确查找（如查找张  输入z ；查找张三  输入zs）。

（2）输入汉字进行搜索时，按照相对模糊的查找（如输入“张”，即查找所有包含“张”字的名单，输入“张三”，即查找所有包含“张三”的名单）。

（3）输入其他字符串查找时，只根据第一个字符进行查询。

程序功能效果如下













代码结构：



MainActivity.java 主界面      MyAdapter.java重写一个adapter     Sort.java处理数据的类      

 


activity_main.xml 主界面

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

<ListView
android:id="@+id/listView1"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
</ListView>

<ImageView
android:id="@+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_gravity="center_vertical|right"
android:scaleType="center"
android:src="@drawable/contact_list_scroll_normal" />

</FrameLayout>

icon.xml当点击导航时，显示在屏幕中间的提示图标

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:background="@drawable/bg_hitchar"
android:gravity="center"
android:maxWidth="100dp"
android:minWidth="100dp"
android:padding="10dp"
android:textColor="#ffffffff"
android:textSize="70sp"
android:visibility="invisible" />

list_item_tag.xml名单组的标题，即对应的首字母

<?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="wrap_content"
android:background="#555555"
android:paddingLeft="10dip">

<TextView
android:id="@+id/group_list_item_text"
android:layout_width="wrap_content"
android:layout_height="20dip"
android:gravity="center_vertical"
android:textColor="#ffffff" />

</LinearLayout>

list_item.xml名单item

<?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="wrap_content"
android:orientation="horizontal"
android:padding="5dip" >

<ImageView
android:layout_width="50dp"
android:layout_height="50dp"
android:src="@drawable/list_addfriend_icon" />

<TextView
android:id="@+id/group_list_item_text"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:gravity="center_vertical"
android:paddingLeft="5dip" />

</LinearLayout>

search.xml搜索框

<?xml version="1.0" encoding="utf-8"?>
<EditText xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/searchText"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="@string/search_text" />

代码实现：

在初始化、设置监听、在主界面添加icon、把search添加进ListView之后，首先，调用Sort中的autoSort(String[])方法，对数据进行排序，然后使用排序后的String[]创建两个ArrayList，第一个ArrayList（newDataArrayList）调用Sort.addChar(String [])方法添加分组的字母，使用于ListView中。第二个ArrayList（checkArrayList）单纯的把排序后的String[]转换成ArrayList用于数据的搜索。
接着使用newDataArrayList创建MyAdapter对象，MyAdapter根据重写的getView方法生成ListView。当点击导航图片时，根据用户点击的位置判断出用户想要点击的字母，然后查找这个字母在newDataArrayList（即MyAda中的mObject）中的位置，使用ListView.setSelectionFromTop()方法把对应的分组字母显示在最上面。使用搜索功能时，判断输入字符串的是字母还是汉字，如果这个字符串都是字母，则每个字母匹配一次，不成功则从checkArrayList中remove掉。如果输入的全部为汉字，则使用String.contains()判断联系人名单包不包含搜索的字符，不包含则remove。在操作完成后的checkArrayList即为搜索到数据，然后通过MyAdapter用ListView现实出来

public int checkSection(String str)

return i;
}
return -1;
}

/**
* 讲26字母添加进list中，方便getView判断

public void initArrayList()

}
