Android学习笔记_SIM卡介绍

一、判断SIM卡属于哪个移动运营商

1、第一种方法:获取手机的IMSI码,并判断是中国移动\中国联通\中国电信

TelephonyManager telManager = (TelephonyManager)

getSystemService(Context.TELEPHONY_SERVICE);

/**获取SIM卡的IMSI码

* SIM卡唯一标识：IMSI 国际移动用户识别码（IMSI：International Mobile Subscriber Identification Number）是区别移动用户的标志，

* 储存在SIM卡中，可用于区别移动用户的有效信息。IMSI由MCC、MNC、MSIN 组成，其中MCC为移动国家号码，由3位数字组成，

* 唯一地识别移动客户所属的国家，我国为460；MNC为网络id，由2位数字组成，

* 用于识别移动客户所归属的移动网络，中国移动为00，中国联通为01,中国电信为03；MSIN为移动客户识别码，采用等长11位数字构成。

* 唯一地识别国内GSM移动通信网中移动客户。所以要区分是移动还是联通，只需取得SIM卡中的MNC字段即可

*/String imsi = telManager.getSubscriberId();

if(imsi!=null){

if(imsi.startsWith("46000") || imsi.startsWith("46002")){//因为移动网络编号46000下的IMSI已经用完，所以虚拟了一个46002编号，134/159号

段使用了此编号

//中国移动

}else if(imsi.startsWith("46001")){

//中国联通

}else if(imsi.startsWith("46003")){

//中国电信

}

}

2、第二种方法：

TelephonyManager telManager = (TelephonyManager)

getSystemService(Context.TELEPHONY_SERVICE);

String operator = telManager.getSimOperator();

if(operator!=null){

if(operator.equals("46000") || operator.equals("46002")){

//中国移动

}else if(operator.equals("46001")){

//中国联通

}else if(operator.equals("46003")){

//中国电信

}

}

二、从SIM卡中获取联系人信息

1、可以通过内容提供者进行访问，下面是主要代码。

Uri uri = Uri.parse("content://icc/adn");

String[] projection = {"_id", "name", "number"};

Cursor cursor = managedQuery(uri, projection, null, null, "name"); if(cursor!=null){

while(cursor.moveToNext()){

String name = cursor.getString(cursor.getColumnIndex("name"));

String phone = cursor.getString(cursor.getColumnIndex("number"));

}

}

/*在文件AndroidManifest.xml中添加权限

Android系统内部通过Contentprovider对外共享Sim卡存放的联系人等信息，你可以通过操作Contentprovider来实现Sim卡信息的添删改查操作。*/

三、删除呼叫记录

1、加入权限

在文件AndroidManifest.xml中添加权限

2、设置内容提供者

负责存放呼叫记录的内容提供者源码在ContactsProvider项目下：

源码路径：com\android\providers\contacts\CallLogProvider.java

使用到的数据库在：

/data/data/com.android.providers.contacts/databases/contacts2.db

表名:calls

呼叫记录有三种类型：

来电：CallLog.Calls.INCOMING_TYPE （常量值：1）

外拔：CallLog.Calls.OUTGOING_TYPE（常量值：2）

3、删除指定号码的来电或未接呼叫记录：

IncomingCallLogContentObserver observer = new IncomingCallLogContentObserver(new Handler());

observer.setNumber("5554");

getContentResolver().registerContentObserver(CallLog.Calls.CONTENT_UR I, true, observer);

private class IncomingCallLogContentObserver extends ContentObserver { private String number;

public IncomingCallLogContentObserver(Handler handler){

super(handler);

}

public void setNumber(String number){

this.number = number;

}

public void onChange(boolean paramBoolean){

ContentResolver contentResolver = getContentResolver();

if(number!=null){

Uri localUri = CallLog.Calls.CONTENT_URI;

Cursor cursor = contentResolver.query(localUri, new String[]{"_id"}, "number=? AND (type=1 OR type=3)",

new String[]{number}, "_id desc limit 1");

if(cursor.moveToFirst()){

contentResolver.delete(localUri, "_id=?", new

String[]{cursor.getString(0)});

}

cursor.close();

}

contentResolver.unregisterContentObserver(this);

}

}
