Android 利用广播实现指定号码的短信的拦截

根据最近的学习内容，今天实现了利用广播进行指定号码的拦截

步骤：
①、写一个数据库的帮助类，实现对数据库的创建，总共创建两个数据库psms（受保护的短信的数据库）和protectedPhone（受保护的联系人数据库），粘代码：

public class DBHelper extends SQLiteOpenHelper {private static final String DB_NAME = "protectedSMS.db";private static final int DB_VERSION = 2;public DBHelper(Context context) {super(context, DB_NAME, null, DB_VERSION);// TODO Auto-generated constructor stub}@Overridepublic void onCreate(SQLiteDatabase db) {// TODO Auto-generated method stubString sql = "create table psms(_id integer primary key autoincrement,address varchar(20),type integer,state integer,body varchar(500),date varchar(20),person varchar(20))";String sql1 = "create table protectedPhone(_id integer primary key autoincrement,person varchar(20),phone varchar(20))";db.execSQL(sql);db.execSQL(sql1);}@Overridepublic void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {// TODO Auto-generated method stub}}

②、写一个类对数据库的增删改查进行封装，代码及注释如下：

/*** 封装DAO，对数据库进制crud操作* * @author Administrator**/
public class ProtectedDAO {private SQLiteDatabase db;public ProtectedDAO(Context context) {DBHelper helper = new DBHelper(context);db = helper.getWritableDatabase();}/*** 插入数据到中* * @param table*            表名* @param values*            对应的键和值* @return 行号*/public long insert(String table, ContentValues values) {// String sql = "insert into person(name,age) values('zhangsan',21)";// db.execSQL(sql);return db.insert(table, null, values);}/*** 更新表中的数据* * @param table*            表名* @param values*            修改后的值* @param whereClause*            条件语句可以使用占位符 ？* @param whereArgs*            使用该数组中的值替换占位符* @return 受影响数据表的行数*/public int update(String table, ContentValues values, String whereClause,String[] whereArgs) {return db.update(table, values, whereClause, whereArgs);}/*** * 删除表中的数据* * @param table*            表名* @param whereClause*            条件语句，可以使用占位符* @param whereArgs*            使用该数组中的值替换占位符* @return 受影响数据的行数*/public int delete(String table, String whereClause, String[] whereArgs) {return db.delete(table, whereClause, whereArgs);}/*** 查询数据* * @param sql*            sql语句，查询语句，可以包含条件，sql语句不用使用分号结尾，系统自动添加* @param selectionArgs*            sql的查询条件可以使用占位符，占位符可以使用selectionArgs的值替代* @return Cursor 游标，可以比作结果集*/public Cursor select(String sql, String[] selectionArgs) {return db.rawQuery(sql, selectionArgs);}/*** 查询数据* * @param table*            表名* @param columns*            查询的列（字段）* @param selection*            where后的条件子句，可以使用占位符* @param selectionArgs*            替换占位符的值，* @param groupBy*            根据某个字段进行分组* @param having*            分组之后再进一步过滤* @param orderBy*            排序* @return Cursor 游标，可以比作结果集*/public Cursor select(String table, String[] columns, String selection,String[] selectionArgs, String groupBy, String having,String orderBy) {// distinct: 消除重复数据项（去掉重复项）// 1、table: 表名// 2、columns: 查询的列（字段）// 3、selection: where后的条件子句，可以使用占位符// 4、selectionArgs: 替换占位符的值// 5、groupBy: 根据某个字段进行分组// 6、having: 分组之后再进一步过滤// 7、orderBy: 排序// limit: 进行分页查询return db.query(table, columns, selection, selectionArgs, groupBy,having, orderBy);}public void close() {if (db != null) {db.close();}}
}

③、创建一个PhoneManagerActivity页面，实现显示，添加及修改，删除受保护的联系人的电话号码及姓名信息

布局文件：

<RelativeLayout xmlns:android=""xmlns:tools=""android:layout_width="match_parent"android:layout_height="match_parent" ><ListView
        android:id="@+id/lv_phone"android:layout_width="match_parent"android:layout_height="match_parent" /></RelativeLayout>

在ActionBar中添加了添加按钮

<menu xmlns:android=""xmlns:tools=""tools:context="com.protect.sms.activity.PhoneManagerActivity" ><item
        android:id="@+id/action_add"android:icon="@drawable/button_03"android:orderInCategory="100"android:showAsAction="always"android:title="新增"/></menu>

PhoneManagerActivity页面处理增加的时间，及处理ListView点击和长按弹出菜单的事件

public class PhoneManagerActivity extends Activity {private ProtectedDAO pd;private ListView lv_phone;private SimpleCursorAdapter adapter;private Cursor cursor;private int position;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_phone_manager);pd = new ProtectedDAO(this);lv_phone = (ListView) findViewById(R.id.lv_phone);flushList();registerForContextMenu(lv_phone);}private void flushList() {cursor = pd.select("protectedPhone", new String[] { "_id", "person","phone" }, null, null, null, null, null);adapter = new SimpleCursorAdapter(this, R.layout.phonelist_item,cursor, new String[] { "person", "phone" }, new int[] {R.id.tv_phone_name, R.id.tv_phone_address },SimpleCursorAdapter.FLAG_REGISTER_CONTENT_OBSERVER);lv_phone.setAdapter(adapter);}@Overridepublic boolean onCreateOptionsMenu(Menu menu) {// Inflate the menu; this adds items to the action bar if it is present.getMenuInflater().inflate(R.menu.phone_manager, menu);return true;}@Overridepublic boolean onOptionsItemSelected(MenuItem item) {// Handle action bar item clicks here. The action bar will// automatically handle clicks on the Home/Up button, so long// as you specify a parent activity in AndroidManifest.xml.int id = item.getItemId();if (id == R.id.action_add) {View view = getLayoutInflater().inflate(R.layout.add_item, null);final EditText et_phone = (EditText) view.findViewById(R.id.et_phone);final EditText et_name = (EditText) view.findViewById(R.id.et_name);Builder builder = new AlertDialog.Builder(this).setIcon(R.drawable.ic_launcher).setTitle("添加受保护的电话号码").setView(view).setPositiveButton("添加", new OnClickListener() {@SuppressWarnings("deprecation")@Overridepublic void onClick(DialogInterface dialog, int which) {// TODO Auto-generated method stubString phone = et_phone.getText().toString().trim();Cursor select = pd.select("protectedPhone",new String[] { "_id", "person", "phone" }," phone =?", new String[] { phone }, null,null, null);if (select.moveToNext()) {Toast.makeText(PhoneManagerActivity.this,"您已添加过该号码，不能重复添加！", Toast.LENGTH_SHORT).show();} else {String name = et_name.getText().toString();ProtectedDAO pd = new ProtectedDAO(PhoneManagerActivity.this);ContentValues values = new ContentValues();values.put("person", name);values.put("phone", phone);long l = pd.insert("protectedPhone", values);if (l > 0) {Toast.makeText(PhoneManagerActivity.this,"添加保护成功", Toast.LENGTH_LONG).show();cursor.requery();}}}}).setNegativeButton("取消", null).setCancelable(false);builder.show();return true;}return super.onOptionsItemSelected(item);}@Overrideprotected void onDestroy() {// TODO Auto-generated method stubsuper.onDestroy();if (pd != null) {pd.close();}}@Overridepublic void onCreateContextMenu(ContextMenu menu, View v,ContextMenuInfo menuInfo) {// TODO Auto-generated method stubsuper.onCreateContextMenu(menu, v, menuInfo);getMenuInflater().inflate(R.menu.phone_menu, menu);AdapterContextMenuInfo acmi = (AdapterContextMenuInfo) menuInfo;position = acmi.position;}@SuppressWarnings("deprecation")@Overridepublic boolean onMenuItemSelected(int featureId, MenuItem item) {// TODO Auto-generated method stubswitch (item.getItemId()) {case R.id.action_update:View view = getLayoutInflater().inflate(R.layout.add_item, null);final EditText et_phone = (EditText) view.findViewById(R.id.et_phone);final EditText et_name = (EditText) view.findViewById(R.id.et_name);final Cursor c = (Cursor) (adapter.getItem(position));et_name.setText(c.getString(c.getColumnIndex("person")));et_phone.setText(c.getString(c.getColumnIndex("phone")));Builder builder = new AlertDialog.Builder(this).setIcon(R.drawable.ic_launcher).setTitle("修改联系人信息").setView(view).setPositiveButton("修改", new OnClickListener() {@Overridepublic void onClick(DialogInterface dialog, int which) {// TODO Auto-generated method stubString phone = et_phone.getText().toString().trim();Cursor select = pd.select("protectedPhone",new String[] { "_id", "person", "phone" }," phone =?", new String[] { phone }, null,null, null);if (select.moveToNext()) {Toast.makeText(PhoneManagerActivity.this,"您已添加过该号码，不能重复添加！", Toast.LENGTH_SHORT).show();} else {String name = et_name.getText().toString();ProtectedDAO pd = new ProtectedDAO(PhoneManagerActivity.this);ContentValues values = new ContentValues();values.put("person", name);values.put("phone", phone);long l = pd.update("protectedPhone",values," _id = ?",new String[] { c.getInt(c.getColumnIndex("_id")) + "" });if (l > 0) {Toast.makeText(PhoneManagerActivity.this,"修改成功", Toast.LENGTH_LONG).show();cursor.requery();} else {Toast.makeText(PhoneManagerActivity.this,"修改失败", Toast.LENGTH_LONG).show();}}}}).setNegativeButton("取消", null).setCancelable(false);builder.show();break;case R.id.action_delete:Builder builder1 = new AlertDialog.Builder(this).setIcon(R.drawable.ic_launcher).setTitle("删除联系人信息").setMessage("删除该联系人信息以后，您与该联系人之间的短信将不会受到保护，是否继续删除？").setPositiveButton("删除", new OnClickListener() {@Overridepublic void onClick(DialogInterface dialog, int which) {// TODO Auto-generated method stubCursor c = (Cursor) (adapter.getItem(position));pd.delete("protectedPhone","_id = ?",new String[] { c.getInt(c.getColumnIndex("_id")) + "" });cursor.requery();}}).setNegativeButton("取消", null).setCancelable(false);builder1.show();break;}cursor.requery();return super.onMenuItemSelected(featureId, item);}
}

④、静态注册广播接收器，实现广播接收器拦截短信的功能

 <manifest xmlns:android=""package="com.protect.sms.activity"android:versionCode="1"android:versionName="1.0" ><!--  必须开启的权限 --><uses-permission android:name="android.permission.RECEIVE_SMS" /><uses-permission android:name="android.permission.SEND_SMS" /><uses-permission android:name="android.permission.FLASHLIGHT" /><uses-permission android:name="android.permission.VIBRATE" /><application
        android:allowBackup="true"android:icon="@drawable/ic_launcher"android:label="@string/app_name"android:theme="@style/AppTheme" ><!--  静态注册广播接收器   priority：优先级，越大越好，但不能超过9999--><receiver android:name=".ProtectedSMSReceiver" ><intent-filter android:priority="1000" ><action android:name="android.provider.Telephony.SMS_RECEIVED" /></intent-filter></receiver></application></manifest>

创建广播接收器，处理onReceive()方法，先获取短信的来源地址，即电话号码，根据该电话号码在受保护的联系人数据库（protectedPhone）信息中查询，若查询到该联系人信息，则进行拦截，存储到数据库，否则，不做处理，发送到手机短信

@Overridepublic void onReceive(Context context, Intent intent) {// TODO Auto-generated method stubString action = intent.getAction();if ("android.provider.Telephony.SMS_RECEIVED".equals(action)) {// StringBuffer sb = new StringBuffer();// 接收有SMS传递的数据Bundle bundle = intent.getExtras();// 判断是否有数据if (bundle != null) {// 通过pdus可以获得接收到的所有短信消息Object[] pdus = (Object[]) bundle.get("pdus");// 构建短信对象array,并依据收到的对象长度来创建array的大小SmsMessage[] messages = new SmsMessage[pdus.length];for (int i = 0; i < pdus.length; i++) {messages[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);}for (SmsMessage message : messages) {// 获得短信来源String address = message.getDisplayOriginatingAddress();if (address.startsWith("+86")) {address = address.substring(address.indexOf("+86")+ "+86".length());}String person = null;ProtectedDAO pd = new ProtectedDAO(context);Cursor cursor = pd.select("protectedPhone", new String[] {"person", "phone" }, "phone = ?",new String[] { address }, null, null, null);if (cursor.moveToNext()) {String body = message.getDisplayMessageBody();String date = formatDate(message.getTimestampMillis());int type = 1;int state = 0;person = cursor.getString(cursor.getColumnIndex("person"));ContentValues values = new ContentValues();values.put("address", address);values.put("type", type);values.put("state", state);values.put("body", body);values.put("date", date);values.put("person", person);long l = pd.insert("psms", values);if (l > 0) {NotificationCompat.Builder builder = new NotificationCompat.Builder(context);builder.setContentTitle((person == null || "null".equals(person)) ? address : person);builder.setContentText(body);builder.setContentInfo(date);builder.setDefaults(Notification.DEFAULT_ALL);builder.setSmallIcon(R.drawable.ic_launcher);// builder.setSmallIcon(R.drawable.ic_launcher);//设置小图标// Notification notification = builder.build();//// 创建通知// 通过系统服务，创建通知管理器NotificationManager manager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);// 发送通知：参数1：通知的唯一标识，参数2：通知的对象Intent intent1 = new Intent(context,DetailsActivity.class);Bundle bd = new Bundle();bd.putString("address", address);bd.putInt("type", type);bd.putInt("state", state);bd.putString("body", body);bd.putString("date", date);intent1.putExtras(bd);PendingIntent pIntent = PendingIntent.getActivity(context, 101, intent1,PendingIntent.FLAG_ONE_SHOT);builder.setContentIntent(pIntent);manager.notify(101, builder.build());// 中止发送通知abortBroadcast();}}}}}}
//格式化时间，即将毫秒数转换成“yyyy-MM-dd HH:mm:ss”的时间@SuppressLint("SimpleDateFormat")public String formatDate(long millis) {SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");String date = df.format(new Date(millis));return date;}

原理就是这样，具体代码过多，这里将不再进行展示。。。。。。
