Android 读取手机联系人、拨号、发送短信及长按菜单的操作

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

 <?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="match_parent"
 android:background="@drawable/bg"
 android:orientation="vertical" >

 <ListView
 android:id="@+id/listView"
 android:layout_width="fill_parent"
 android:layout_height="fill_parent"
 android:layout_marginLeft="5dip"
 android:cacheColorHint="#00000000"
 android:divider="@drawable/divider_horizontal_bright"
 android:paddingRight="5dip" >
 </ListView>

 </LinearLayout>

b.list_item.xml ListView的列表项布局文件，相当于展示模版

<?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" >

<ImageView
android:id="@+id/imgView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:contentDescription="@string/photo"
android:paddingRight="2dip" />

<TextView
android:id="@+id/name"
android:layout_width="80dip"
android:layout_height="wrap_content"
android:layout_marginLeft="10dip"
android:paddingTop="8dip"
android:singleLine="false"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textColor="#ffffff" />

<TextView
android:id="@+id/number"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginRight="6dip"
android:paddingTop="8dip"
android:singleLine="false"
android:textColor="#ffffff"
android:textAppearance="?android:attr/textAppearanceMedium"/>

</LinearLayout>

　　

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

<?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="match_parent"
android:orientation="vertical" >

<TextView
android:id="@+id/ymw"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceMedium"/>

</LinearLayout>

2.Java实现代码如下↓

a，MainActivity.java 程序运行的入口文件

 package com.example.myandroid;

 import java.util.ArrayList;
 import java.util.HashMap;
 import java.util.Iterator;

 import android.app.Activity;
 import android.content.ContentResolver;
 import android.content.Intent;
 import android.database.Cursor;
 import android.net.Uri;
 import android.os.Bundle;
 import android.provider.ContactsContract;
 import android.provider.ContactsContract.CommonDataKinds;
 import android.view.ContextMenu;
 import android.view.ContextMenu.ContextMenuInfo;
 import android.view.MenuItem;
 import android.view.View;
 import android.view.View.OnCreateContextMenuListener;
 import android.widget.AdapterView;
 import android.widget.AdapterView.OnItemClickListener;
 import android.widget.ListView;
 import android.widget.SimpleAdapter;
 import android.widget.Toast;

 import com.ymw.details.Detail;

 public class MainActivity extends Activity {

 @Override
 public void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.main);

 final ListView listView = (ListView) findViewById(R.id.listView);

 // 生成动态数组，加入数据
 ArrayList<HashMap<String, Object>> listItem = fillMaps();

 SimpleAdapter listItemAdapter = new SimpleAdapter(this, listItem,
 R.layout.list_item,
 new String[] { "imgView", "name", "number" }, new int[] {
 R.id.imgView, R.id.name, R.id.number });
 listView.setAdapter(listItemAdapter);

 // 添加单击事件
 listView.setOnItemClickListener(new OnItemClickListener() {
 @Override
 public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
 long arg3) {
 HashMap<String, String> map = (HashMap<String, String>) listView
 .getItemAtPosition(arg2);
 String name = map.get("name");
 Toast toast = Toast.makeText(getApplicationContext(), "第"
 + arg2 + "项" + name, Toast.LENGTH_LONG);
 toast.show();
 String phoneNum = map.get("number");
 Intent intent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:"
 + phoneNum));
 startActivity(intent);
 }
 });

 // 添加长按菜单
 listView.setOnCreateContextMenuListener(new OnCreateContextMenuListener() {
 public void onCreateContextMenu(ContextMenu menu, View v,
 ContextMenuInfo menuInfo) {
 menu.setHeaderTitle("长按菜单-ContextMenu");
 menu.add(0, 0, 0, "查看详细");
 menu.add(0, 1, 0, "发送信息");
 menu.add(0, 2, 0, "删除联系人");
 }
 });
 }

 public boolean onContextItemSelected(MenuItem item) {
 // setTitle("点击了长按菜单里面的第"+item.getItemId()+"个项目");
 Toast.makeText(getApplicationContext(),
 "选择了" + item.getItemId() + item.getTitle() + "项",
 Toast.LENGTH_LONG).show();

 int id = item.getItemId();
 // 查看详细
 if (id == 0) {
 Intent intent = new Intent();
 intent.putExtra("ymw", item.getTitle());
 intent.setClass(MainActivity.this, Detail.class);
 startActivity(intent);
 }
 // 发送短信
 else if (id == 1) {
 Uri uri = Uri.parse("smsto://18664599745");
 Intent intent = new Intent(Intent.ACTION_SENDTO, uri);
 intent.putExtra("sms_body", "ymw-LOVE-yh");
 startActivity(intent);
 }
 // 删除联系人
 else if (id == 2) {
 }
 return super.onContextItemSelected(item);
 }

 // 获取手机联系人列表方法一
 public ArrayList<HashMap<String, Object>> GetContects() {
 ArrayList<HashMap<String, Object>> list = new ArrayList<HashMap<String, Object>>();
 Cursor cursor = getContentResolver().query(
 ContactsContract.Contacts.CONTENT_URI,
 null,
 null,
 null,
 ContactsContract.Contacts.DISPLAY_NAME
 + " COLLATE LOCALIZED ASC");

 if (cursor.moveToFirst()) {
 int idColumn = cursor.getColumnIndex(ContactsContract.Contacts._ID);
 int nameColum = cursor
 .getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);
 do {
 String contactId = cursor.getString(idColumn);
 String disPlayNameString = cursor.getString(nameColum);

 // 查看有多少电话号码 没有则返回为0
 int phoneCount = cursor
 .getInt(cursor
 .getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));

 if (phoneCount > 0) {
 // 获得联系人的电话号码
 Cursor phones = getContentResolver().query(
 ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
 null,
 ContactsContract.CommonDataKinds.Phone.CONTACT_ID
 + "=" + contactId, null, null);
 HashMap<String, Object> map = new HashMap<String, Object>();
 map.put("imgView", R.drawable.ic_launcher);
 map.put("name", disPlayNameString);
 list.add(map);

 }
 } while (cursor.moveToNext());
 if (cursor != null)
 cursor.close();
 }
 return list;
 }

 // 获取联系人方法二
 public ArrayList<HashMap<String, Object>> fillMaps() {
 ArrayList<HashMap<String, Object>> items = new ArrayList<HashMap<String, Object>>();

 ContentResolver cr = getContentResolver();
 HashMap<String, ArrayList<String>> hashMap = new HashMap<String, ArrayList<String>>();
 Cursor phone = cr.query(CommonDataKinds.Phone.CONTENT_URI,
 new String[] { CommonDataKinds.Phone.CONTACT_ID,
 CommonDataKinds.Phone.DISPLAY_NAME,
 CommonDataKinds.Phone.NUMBER,
 CommonDataKinds.Phone.DATA1
 // CommonDataKinds.StructuredPostal.DATA3,
 }, null, null, null);
 while (phone.moveToNext()) {
 String contactId = phone.getString(phone
 .getColumnIndex(CommonDataKinds.Phone.CONTACT_ID));
 String displayName = phone.getString(phone
 .getColumnIndex(CommonDataKinds.Phone.DISPLAY_NAME));
 String PhoneNumber = phone
 .getString(phone
 .getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
 String address = phone.getString(phone
 .getColumnIndex(CommonDataKinds.Phone.DATA1));

 // 以contactId为主键，把同一人的所有电话都存到一起。
 ArrayList<String> ad = hashMap.get(contactId);
 if (ad == null) {
 ad = new ArrayList<String>();
 ad.add(displayName);
 ad.add(PhoneNumber);
 // ad.add(address);

 hashMap.put(contactId, ad);
 } else {
 ad.add(PhoneNumber);
 }

 }
 phone.close();

 ArrayList<String> tmpList;
 String tmpStr = "";
 int k;
 Iterator iter = hashMap.entrySet().iterator();
 while (iter.hasNext()) {
 HashMap.Entry entry = (HashMap.Entry) iter.next();
 Object key = entry.getKey();
 Object val = entry.getValue();

 tmpList = (ArrayList) val;
 tmpStr = "";
 for (k = 1; k < tmpList.size(); k++) {
 tmpStr = tmpStr + tmpList.get(k) + ',';
 }
 tmpStr = GetString(tmpStr);
 HashMap<String, Object> tmpMap = new HashMap<String, Object>();
 tmpMap.put("name", tmpList.get(0));
 tmpMap.put("number", tmpStr);
 tmpMap.put("imgView", R.drawable.ic_launcher);
 items.add(tmpMap);
 }
 return items;
 }

 private String GetString(String str) {

 String strLast = "";
 int i = str.lastIndexOf(",");
 if (i > 0) {
 strLast = str.substring(0, str.length() - 1);
 }
 return strLast.replace(" ", "").replace(",", "\n").replace("+86", "");
 }

 }

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

 package com.ymw.details;

 import com.example.myandroid.R;

 import android.app.Activity;
 import android.content.Intent;
 import android.os.Bundle;
 import android.widget.TextView;

 public class Detail extends Activity {
 @Override
 protected void onCreate(Bundle savedInstanceState) {
 // TODO Auto-generated method stub
 super.onCreate(savedInstanceState);
 setContentView(com.example.myandroid.R.layout.phonedetails);

 Intent intent = getIntent();
 String strPara = intent.getStringExtra("ymw");

 TextView tView = (TextView) findViewById(R.id.ymw);
 tView.setText(strPara);
 }
 }

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。
