小编给大家分享一下android ContentResolver如何获取手机电话号码和短信内容，希望大家阅读完这篇文章之后都有所收获，下面让我们一起去探讨吧！
通过ContentResolver 获取到手机的联系人跟手机短信信息并显示出来，具体内容如下
1、实现的代码：
package com.example.phone;
import java.text.SimpleDateFormat;
import java.util.ArrayList;
import java.util.Date;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import android.net.Uri;
import android.os.Bundle;
import android.provider.ContactsContract;
import android.provider.ContactsContract.PhoneLookup;
import android.app.Activity;
import android.content.ContentResolver;
import android.database.Cursor;
import android.database.sqlite.SQLiteException;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;
public class MainActivity extends Activity implements OnClickListener{
private TextView text;
private Button button;
private Button sms;
HashMap<String, Object> map = new HashMap<String, Object>();
List<String> con = new ArrayList<String>();
String msg;//联系人姓名+号码
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initUI();
}
private void initUI() {
// TODO Auto-generated method stub
text = (TextView)findViewById(R.id.text);
button = (Button)findViewById(R.id.button);//获取手机电话号码
button.setOnClickListener(this);
sms = (Button)findViewById(R.id.sms);//获取手机短信信息
sms.setOnClickListener(this);
}
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch(v.getId()){
case R.id.button:
getPhoneNumber();//获取手机电话号码
break;
case R.id.sms://获取手机短信内容
getSmsMessage();
Map<String,Object> item = new HashMap<String,Object>();
for(int i= 0;i<con.size();i++){
text.setText(item.put("con", con.get(i))+"");//仅显示一条
System.out.println("ningshengcai:"+item.put("con", con.get(i)));//打印显示全部数据
}
break;
default :
break;
}
}
/**
* 获取手机联系人号码
*/
public void getPhoneNumber(){
// smslist=getListView();
//得到ContentResolver对象
ContentResolver cr = getContentResolver();
//取得电话本中开始一项的光标
Cursor cursor = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
while (cursor.moveToNext())
{
// 取得联系人名字
int nameFieldColumnIndex = cursor.getColumnIndex(PhoneLookup.DISPLAY_NAME);
String name = cursor.getString(nameFieldColumnIndex);
//name += (name);
// 取得联系人ID
String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
Cursor phone = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = "+ contactId, null, null);
// 取得电话号码(可能存在多个号码)
while (phone.moveToNext())
{
String strPhoneNumber = phone.getString(phone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
System.out.println(name+":"+strPhoneNumber);
msg += name+":"+strPhoneNumber+"\n";
text.setText(msg);
}
phone.close();
}
cursor.close();
}
/**
* 获取短信信息
* @return smsBuilder.toString()
*/
@SuppressWarnings("unused")
public String getSmsMessage(){
final String SMS_URI_ALL = "content://sms/";
final String SMS_URI_INBOX = "content://sms/inbox";
final String SMS_URI_SEND = "content://sms/sent";
final String SMS_URI_DRAFT = "content://sms/draft";
StringBuilder smsBuilder = new StringBuilder();
try{
ContentResolver cr = getContentResolver();
String[] projection = new String[]{"_id", "address", "person",
"body", "date", "type"};
Uri uri = Uri.parse(SMS_URI_ALL);
Cursor cur = cr.query(uri, projection, null, null, "date desc");
if (cur.moveToFirst()) {
String name;
String phoneNumber;
String smsbody;
String date;
String type;
int nameColumn = cur.getColumnIndex("person"); //发送人
int phoneNumberColumn = cur.getColumnIndex("address"); //号码
int smsbodyColumn = cur.getColumnIndex("body"); //内容
int dateColumn = cur.getColumnIndex("date"); //时间
int typeColumn = cur.getColumnIndex("type"); //接收还是发送
do{
name = cur.getString(nameColumn);
phoneNumber = cur.getString(phoneNumberColumn);
smsbody = cur.getString(smsbodyColumn);
SimpleDateFormat dateFormat = new SimpleDateFormat(
"yyyy-MM-dd hh:mm:ss");
Date d = new Date(Long.parseLong(cur.getString(dateColumn)));
date = dateFormat.format(d);
int typeId = cur.getInt(typeColumn);
if(typeId == 1){
type = "接收";
} else if(typeId == 2){
type = "发送";
} else {
type = "";
}
//System.out.println("nsc :"+name+":"+phoneNumber+":"+smsbody+":"+date+":"+type +"\n");
String smsmsg = name+":"+phoneNumber+":"+smsbody+":"+date+":"+type+"\n";
con.add(smsmsg);
if(smsbody == null) smsbody = "";
}while(cur.moveToNext());
} else {
smsBuilder.append("no result!");
}
smsBuilder.append("getSmsInPhone has executed!");
} catch(SQLiteException ex) {
Log.d("SQLiteException in getSmsInPhone", ex.getMessage());
}
return smsBuilder.toString();
}
}2、代码布局：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" tools:context=".MainActivity" > <Button android:id="@+id/button" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/ph"/> <Button android:id="@+id/sms" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/sms"/> <ScrollView android:layout_width="fill_parent" android:layout_height="wrap_content"> <TextView android:id="@+id/text" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/hello_world" /> </ScrollView> </LinearLayout>
3、需要用到的权限
<uses-permission android:name="android.permission.READ_CONTACTS" /> <uses-permission android:name="android.permission.WRITE_SMS" /> <uses-permission android:name="android.permission.READ_SMS" /> <uses-permission android:name="android.permission.READ_PHONE_STATE" />
Android是一种基于Linux内核的自由及开放源代码的操作系统，主要使用于移动设备，如智能手机和平板电脑，由美国Google公司和开放手机联盟领导及开发。
