Android编程之SMS读取短信并保存到SQLite的方法_Android

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;
