简单的读取收件箱信息

核心代码

private void getMsgs(){
    Uri uri = Uri.parse("content://sms/");
    ContentResolver resolver = getContentResolver();
    //获取的是哪些列的信息
    Cursor cursor = resolver.query(uri, new String[]{"address","date","type","body"}, null, null, null);
    while(cursor.moveToNext())
    {
        String address = cursor.getString(0);
        String date = cursor.getString(1);
        String type = cursor.getString(2);
        String body = cursor.getString(3);
        System.out.println("地址:" + address);
        System.out.println("时间:" + date);
        System.out.println("类型:" + type);
        System.out.println("内容:" + body);
        System.out.println("======================");
    }
    cursor.close();
}

AndroidManifest.xml加入读取收件箱的权限

<uses-permission android:name="android.permission.READ_SMS"/>

简单的往收件箱里插入一条信息

核心代码

private void insertMsg() {
    ContentResolver resolver = getContentResolver();
    Uri uri = Uri.parse("content://sms/");
    ContentValues conValues = new ContentValues();
    conValues.put("address", "123456789");
    conValues.put("type", 1);
    conValues.put("date", System.currentTimeMillis());
    conValues.put("body", "no zuo no die why you try!");
    resolver.insert(uri, conValues);
    Log.e("HeHe", "短信插入完毕~");
}

注意事项：
上述代码在4.4以下都可以实现写入短信的功能，而5.0上就无法写入，原因是： 从5.0开始，默认短信应用外的软件不能以写入短信数据库的形式发短信！
