黑名单电话和短信拦截

实现思路

1.MyDBhelper 创建数据库和3张表格

public class MyDBhelper extends SQLiteOpenHelper{public MyDBhelper(Context context) {super(context, "phone.db", null, 1);//固话构造方法，避免输入错误Log.i("TAG", "onCreate2");}@Overridepublic void onCreate(SQLiteDatabase db) {// 创建3张表//1黑名单电话表 backphone(id,number)Log.i("TAG", "onCreate");String sql = "create table if not exists backphone("+ "_id integer primary key autoincrement,"+ "number text not null"+ ")";db.execSQL(sql);//2黑名单的电话记录 phonelist(id,number,type,date) 会话，谁，打进打出，时间String sql2 = "create table if not exists phonelist("+ "_id integer primary key autoincrement,"+ "number text not null,"+ "type integer,"+ "date integer"+ ")";db.execSQL(sql2);//3黑名单的短信记录 smslist(id,number,body,date)String sql3 = "create table if not exists smslist("+ "id integer primary key autoincrement,"+ "number text not null,"+ "body text,"+ "date integer"+ ")";db.execSQL(sql3);Log.d("TAG", "MyDBhelper onCreate ok");}@Overridepublic void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {//表结构有变化时候>修改版本>启动此方法// TODO Auto-generated method stub}}

2.DBManager 判断是不是黑名单，存入黑名单表，存入黑名单通话记录表，存入短信记录表

public class DBManager {MyDBhelper helper = null;public DBManager(Context context){helper = new MyDBhelper(context);}//添加黑名单电话public void insertBlackNumber(String number){SQLiteDatabase sdb = helper.getWritableDatabase();ContentValues values = new ContentValues();values.put("number", number);sdb.insert("backphone", null, values);Log.i("TAG", "加入黑名单成功");}//判断是不是黑名单电话public boolean isBlackNunber(String number){SQLiteDatabase sdb = helper.getReadableDatabase();String selection = "number=?";Cursor cursor = sdb.query("backphone",null,selection, new String[]{number},null, null,null);if(cursor.moveToNext()){return true;}cursor.close();return false;}//打入的黑电话号码保存在列表中public void insertPhone(Phone phone){SQLiteDatabase sdb = helper.getWritableDatabase();ContentValues values = new ContentValues();values.put("number", phone.getNumber());values.put("type", phone.getType());values.put("date", phone.getDate());sdb.insert("phonelist", null, values); Log.d("TAG", "insertPhone ok");}//将黑名单发过来的短信保存在短信列表中public void insertSMS(SMS sms){SQLiteDatabase sdb = helper.getWritableDatabase();ContentValues values = new ContentValues();values.put("number", sms.getNumber());values.put("body", sms.getBody());values.put("date", sms.getDate());sdb.insert("smslist", null, values);}}

3.PhoneService 拦截短信，拦截打出黑名单电话

/*** 1.黑名单短信的拦截 2/3.黑名单打进（出）电话时候挂断电话* * @author tarena**/public class PhoneService extends Service {public final static String SMS_RECEIVI = "android.provider.Telephony.SMS_RECEIVED";public final static String OUTGOING_CALL = "android.intent.action.NEW_OUTGOING_CALL";DBManager dbmanager;@Overridepublic void onCreate() {super.onCreate();dbmanager = new DBManager(this);// 服务中注册广播接收器// 拦截短信，对黑名单处理registerPhoneReceiver();Log.e("TAG", "服务已经启动");}private void registerPhoneReceiver() {receiver = new PhoneReceiver();IntentFilter filter = new IntentFilter();//定义接收短信广播filter.addAction(SMS_RECEIVI);//订阅打出电话的有序广播filter.addAction(OUTGOING_CALL);filter.setPriority(1000);registerReceiver(receiver, filter);}PhoneReceiver receiver;public class PhoneReceiver extends BroadcastReceiver {// 收到短信内容会回调@Overridepublic void onReceive(Context context, Intent intent) {// 拆解短信1.拿到电话号码2.判断是否为黑名单String action = intent.getAction();if (SMS_RECEIVI.equals(action)) {//回掉原因是收到短信Bundle b = intent.getExtras();Log.i("TAG", "短信拦截广播");String number = SMSManager.getNumberFromSMS(b);// 判断是不是黑名单发过来的if (dbmanager.isBlackNunber(number)) {String body = SMSManager.getBodyFromSMS(b);Log.i("TAG", "黑名单短信发过来");// 拦截短信abortBroadcast();// 存入短信列表SMS sms = new SMS();sms.setBody(body);sms.setDate(System.currentTimeMillis());sms.setNumber(number);}}else if(OUTGOING_CALL.endsWith(action)){//回调原因是因为打出号码Log.i("TAG", "打出电话");String number = getResultData();//拿到的是一手数据(从广播中获取电话号码)//如果是黑名单则拦截黑名单if(dbmanager.isBlackNunber(number)){Log.i("TAG", "打出黑名单电话号码");//将电话置空setResultData(null);//记录信息Phone phone = new Phone();phone.setType(2);phone.setDate(System.currentTimeMillis());phone.setNumber(number);//存入电话信息表dbmanager.insertPhone(phone);}}}}@Overridepublic IBinder onBind(Intent intent) {return null;}@Overridepublic void onDestroy() {// TODO Auto-generated method stubsuper.onDestroy();if(receiver!=null){unregisterReceiver(receiver);Log.i("TAG", "unregisterReceiver");receiver=null;}}}

4.Phone SMS 封装实体类

public class Phone {private int _id;private String number;private int type;private long date;public Phone() {super();// TODO Auto-generated constructor stub}public Phone(int _id, String number, int type, long date) {super();this._id = _id;this.number = number;this.type = type;this.date = date;}public int get_id() {return _id;}public void set_id(int _id) {this._id = _id;}public String getNumber() {return number;}public void setNumber(String number) {this.number = number;}public int getType() {return type;}public void setType(int type) {this.type = type;}public long getDate() {return date;}public void setDate(long date) {this.date = date;}@Overridepublic String toString() {return "Phone [_id=" + _id + ", number=" + number + ", type=" + type + ", date=" + date + "]";}
}

public class SMS {private int id;private String number;private String body;private long date;public SMS() {super();// TODO Auto-generated constructor stub}public SMS(int id, String number, String body, long date) {super();this.id = id;this.number = number;this.body = body;this.date = date;}public int getId() {return id;}public void setId(int id) {this.id = id;}public String getNumber() {return number;}public void setNumber(String number) {this.number = number;}public String getBody() {return body;}public void setBody(String body) {this.body = body;}public long getDate() {return date;}public void setDate(long date) {this.date = date;}@Overridepublic String toString() {return "SMS [id=" + id + ", number=" + number + ", body=" + body + ", date=" + date + "]";}
}

5.SMSManager 获取短信号码，获取短信内容

public class SMSManager {/** 根据拦击的短信来查询电话号码 */public static String getNumberFromSMS(Bundle b) {Object[] pdus = (Object[]) b.get("pdus");SmsMessage[] smses = new SmsMessage[pdus.length];smses[0] = SmsMessage.createFromPdu((byte[]) pdus[0]);String number = smses[0].getOriginatingAddress();return number;}/*** 获得短信内容* * @return*/public static String getBodyFromSMS(Bundle b) {//Android设备接收到的SMS是以pdu形式的(protocol description unit)。所以从intent提取数据时就会遇到pdusObject[] pdus = (Object[]) b.get("pdus");SmsMessage[] smses = new SmsMessage[pdus.length];//提取短信内容for (int i = 0; i < pdus.length; i++) {smses[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);}StringBuilder builder = new StringBuilder();//短信内容拼接（大于140字节）for (int i = 0; i < smses.length; i++) {builder.append(smses[i].getMessageBody());}return builder.toString();}}

6.mainActivity 获取拦截号码，启动和拦截服务

public class MainActivity extends Activity {private EditText etadd;private DBManager dbmanager;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);etadd = (EditText) findViewById(R.id.etadd_blackphone);dbmanager = new DBManager(this);}public void add(View v){//添加黑名单String number = etadd.getText().toString();dbmanager.insertBlackNumber(number);Toast.makeText(this, "添加成功", 0).show();etadd.setText("");}public void start(View v){//开启监听Intent intent  = new Intent(this, PhoneService.class);startService(intent);}public void stop(View v){//停止监听Intent intent = new Intent(this, PhoneService.class);stopService(intent);}
}

添加拦截号码后启动服务拦截短信（abortBroadcast()）和电话广播（setResultData(null)），实现拦截；

附加：清单配置文件和布局文件
