本示例实现了读取手机联系人，拨号、发送短信及长按出现菜单选项的操作↓
1.Andrid项目结构图↓主要操作图中红色方框内的文件。
2.首先布局代码如下↓
a, main.xml
程序运行的主界面，主要用ListView列表控件展示手机联系人
1 <?xml version="1.0" encoding="utf-8"?>
2 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
3 android:layout_width="match_parent"
4 android:layout_height="match_parent"
5 android:background="@drawable/bg"
6 android:orientation="vertical" >
7
8 <ListView
9 android:id="@+id/listView"
10 android:layout_width="fill_parent"
11 android:layout_height="fill_parent"
12 android:layout_marginLeft="5dip"
13 android:cacheColorHint="#00000000"
14 android:divider="@drawable/divider_horizontal_bright"
15 android:paddingRight="5dip" >
16 </ListView>
17
18 </LinearLayout>
b.list_item.xml
ListView的列表项布局文件，相当于展示模版

c,phonedetails.xml
长按菜单显示联系人详细布局界面，示例只做了跳转展示

b,Detail.java
主界面长按菜单显示联系人详细的跳转界面，接受主界面传来的参数
1 package com.ymw.details;
2
3 import com.example.myandroid.R;
4
5 import android.app.Activity;
6 import android.content.Intent;
7 import android.os.Bundle;
8 import android.widget.TextView;
9
10 public class Detail extends Activity {
11 @Override
12 protected void onCreate(Bundle savedInstanceState) {
13 // TODO Auto-generated method stub
14 super.onCreate(savedInstanceState);
15 setContentView(com.example.myandroid.R.layout.phonedetails);
16
17 Intent intent = getIntent();
18 String strPara = intent.getStringExtra("ymw");
19
20 TextView tView = (TextView) findViewById(R.id.ymw);
21 tView.setText(strPara);
22 }
23 }
3.获取手机联系人和拨号发短信等需要配置权限↓
在AndroidManifest.xml文件中的application节点上加入如下代码<!--添加权限-->
<uses-permission android:name="android.permission.SEND_SMS"/>
<uses-permission android:name="android.permission.CALL_PHONE"/>
<uses-permission android:name="android.permission.READ_CONTACTS"/>
4.使用Android模拟器或连接Android智能手机运行本程序可以看到手机联系人列表，
单击某个联系人会直接拨号，长按某个联系人会出现菜单选项，可以选择发送短信。
