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：

package com.internal.message;

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";

	    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");

	           //    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(

	                Date d = new Date(Long.parseLong(cur.getString(dateColumn)));   
	                date = dateFormat.format(d);

	                    type = "草稿";

	        }
	        cur.close();
	        cur=null;
	    } catch(SQLiteException ex) {   
	        Log.e("SQLiteException in getSmsInPhone", ex.getMessage());   
	    }   
	    
	} 
	/**

				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()){

}

怎么样，其实就是获取数据库内容而以，是不是很容易，希望对大家有帮助。
