这个布局是自己为了自己设置是否显示归属地的。

public class CallAddressDao {//数据库路径private static final String PATH = "data/data/com.sjr.calladdress/files/address.db";/*** 从数据库中获取手机归属地* @param number* @return 手机归属地*/public static String getCallAddress(String number){String callAddress = "未知号码";//获取数据库对象SQLiteDatabase database = SQLiteDatabase.openDatabase(PATH, null,SQLiteDatabase.OPEN_READONLY);//正则表达式匹配if (number.matches("^1[3-8]\\d{9}$")) {//匹配器11位手机号Cursor cursor = database.rawQuery("select location from data2 where id=(select outkey from data1 where id=?)",new String[]{number.substring(0, 7)});//截取前七个if (cursor.moveToNext())callAddress = cursor.getString(0);cursor.close();}else if (number.matches("^\\d+$")){//匹配数字switch (number.length()){case 3:callAddress = "报警电话";//三位数就是报警电话break;case 4:callAddress = "模拟器";break;case 5:callAddress = "客服电话";break;case 7:case 8:callAddress = "本地电话";break;default:if (number.startsWith("0")&&number.length()>10){//有可能是长途电话//有些区号是4位，有些区号是3位（包括0）
//                        先查询4位区号Cursor cursor = database.rawQuery("select location from data2 where area =?",new String[]{number.substring(1,4)});if (cursor.moveToNext())callAddress = cursor.getString(0);else {cursor.close();//查询3位区号cursor = database.rawQuery("select location from data2 where area =?",new String[]{number.substring(1,3)});if (cursor.moveToNext())callAddress = cursor.getString(0);cursor.close();}}break;}}database.close();//关闭数据库return callAddress;}
}

 //获取数据库对象SQLiteDatabase database = SQLiteDatabase.openDatabase(PATH, null,SQLiteDatabase.OPEN_READONLY);

这里我设定的数据库路径是：

data/data/com.sjr.calladdress/files/address.db

这不能是assets文件夹下面的，只能是data/data/包名/ 目录下，不然是访问不到的，但是这时这个路径下是没有数据库的，所以我就在第一次进入主界面的时候先把数据库拷到这个目录下

    /*** 把assets目录下的数据库拷贝到data/data目录下** @param dbName*/private void copyDB(String dbName) {
//                File filesDir = getFilesDir();///data/data/com.sjr.calladdress/files
//        Log.d("print","路径:"+filesDir.getAbsolutePath());File desFile = new File(getFilesDir(), dbName);//要拷贝的目标地址if (desFile.exists()) {//如果已经存在,就不进行拷贝工作直接返回Log.d("print", "数据库" + dbName + "已经存在");return;}//否则就进行数据库拷贝FileOutputStream out = null;InputStream in = null;try {in = getAssets().open(dbName);//读写assets文件夹下的数据库out = new FileOutputStream(desFile);//写入data目录int len = 0;byte[] buffer = new byte[1024];while ((len = in.read(buffer)) != -1) {out.write(buffer, 0, len);}} catch (IOException e) {e.printStackTrace();} finally {try {if (out != null)out.close();if (in != null)in.close();} catch (IOException e) {e.printStackTrace();}}}

上面的代码就把数据库从assets文件夹下面拷贝到data目录下了

}

先解决监听去电广播的问题，写一个广播接收者，去接收去电广播，注意监听去电广播是要权限的，权限如下

  /*** 去电广播* 监听去电广播需要下面的权限* <uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" />*/class OutCallReceiver extends BroadcastReceiver {@Overridepublic void onReceive(Context context, Intent intent) {String number = getResultData();//获取去电号码String address = CallAddressDao.getCallAddress(number);//将去电号码跟数据库的进行比对showView(address);}}

   //动态注册去电广播IntentFilter filter = new IntentFilter(Intent.ACTION_NEW_OUTGOING_CALL);registerReceiver(mReceiver, filter);

在服务关闭的时候就取消注册：

 /*** 服务销毁的时候会回调这个方法*/@Overridepublic void onDestroy() {mTM.listen(mListener, PhoneStateListener.LISTEN_NONE);//停止来电监听unregisterReceiver(mReceiver);//注销监听去电广播}
