Android SMS(二)—— 读取短信保存到 SQLite

it2022-05-06  0

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;
