Android学习笔记_47_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
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
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 <uses-permission android:name="android.permission.READ_CONTACTS" /> <uses-permission android:name="android.permission.WRITE_CONTACTS" />
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_URI, 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); } }
