    本文实例讲述了Android编程实现读取手机联系人、拨号、发送短信及长按菜单操作方法。分享给大家供大家参考,具体如下:

    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" ><ListViewandroid: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" ><ImageViewandroid:id="@+id/imgView"android:layout_width="wrap_content"android:layout_height="wrap_content"android:contentDescription="@string/photo"android:paddingRight="2dip" /><TextViewandroid: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" /><TextViewandroid: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" ><TextViewandroid: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 {@Overridepublic 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() {@Overridepublic 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0int 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 {@Overrideprotected void onCreate(Bundle savedInstanceState) {// TODO Auto-generated method stubsuper.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。

    希望本文所述对大家Android程序设计有所帮助。
