Android编程之SMS读取短信并保存到SQLite的方法
作者：阳光岛主
这篇文章主要介绍了Android编程之SMS读取短信并保存到SQLite的方法,涉及Android针对SMS短信及SQLite数据库的相关操作技巧,需要的朋友可以参考下
本文实例讲述了Android编程之SMS读取短信并保存到SQLite的方法。分享给大家供大家参考，具体如下：
Android 之 SMS 短信在Android系统中是保存在SQLite数据库中的，但不让其它程序访问（Android系统的安全机制）
现在我们在读取手机内的SMS短信，先保存在我们自己定义的SQLite数据库中，然后读取SQLite数据库提取短信，并显示
SMS短信SQLite存取代码：
package com.homer.sms;
import java.sql.Date;
import java.text.SimpleDateFormat;
import org.loon.wsi.R;
import android.app.Activity;
import android.content.Context;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.graphics.Color;
import android.net.Uri;
import android.os.Bundle;
import android.util.Log;
import android.widget.TableLayout;
import android.widget.TableRow;
import android.widget.TableRow.LayoutParams;
import android.widget.TextView;
