1.号码归属地查询的UI

2.号码归属地查询的原理

1.查询数据库

3.号码归属地的查询实现

1、把数据库拷贝到assets目录并创建包com.itheima.mobilesafe.db.dao包创建该类

      file:///android_aset/address.db 这种无法访问

2.  在SplashActivit页面做从Assets目录拷贝到data/data/<包名>/files/address.db数据库的代码

/** * //path 把address.db这个数据库拷贝到data/data/《包名》/files/address.db */private void copyDB() {//只要你拷贝了一次，我就不要你再拷贝了try {File file = new File(getFilesDir(), "address.db");if(file.exists()&&file.length()>0){//正常了，就不需要拷贝了Log.i(TAG, "正常了，就不需要拷贝了");}else{InputStream is = getAssets().open("address.db");FileOutputStream fos = new FileOutputStream(file);byte[] buffer = new byte[1024];int len = 0;while((len = is.read(buffer))!= -1){fos.write(buffer, 0, len);}is.close();fos.close();}} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}}

3.操作数据库放在独立的包下

  使用正则表达式输入号码

public class NumberAddressQueryUtils {private static String path = "data/data/com.itheima.mobilesafe/files/address.db";/** * 传一个号码进来，返回一归属地回去 *  * @param number * @return */public static String queryNumber(String number) {String address = number;// path 把address.db这个数据库拷贝到data/data/《包名》/files/address.dbSQLiteDatabase database = SQLiteDatabase.openDatabase(path, null,SQLiteDatabase.OPEN_READONLY);// 手机号码 13 14 15 16 18// 手机号码的正则表达式判断\d需要加\转义if (number.matches("^1[34568]\\d{9}$")) {// 手机号码Cursor cursor = database.rawQuery("select location from data2 where id = (select outkey from data1 where id = ?)",new String[] { number.substring(0, 7) });while (cursor.moveToNext()) {String location = cursor.getString(0);address = location;}cursor.close();} else {// 其他的电话号码switch (number.length()) {case 3:// 110address = "匪警号码";break;case 4:// 5554address = "模拟器";break;case 5:// 10086address = "客服电话";break;case 7://address = "本地号码";break;case 8:address = "本地号码";break;default:// /处理长途电话 10if (number.length() > 10 && number.startsWith("0")) {// 010-59790386Cursor cursor = database.rawQuery("select location from data2 where area = ?",new String[] { number.substring(1, 3) });while (cursor.moveToNext()) {String location = cursor.getString(0);address = location.substring(0, location.length() - 2);}cursor.close();// 0855-59790386cursor = database.rawQuery("select location from data2 where area = ?",new String[] { number.substring(1, 4) });while (cursor.moveToNext()) {String location = cursor.getString(0);address = location.substring(0, location.length() - 2);}}break;}}return address;}}

 

4.号码归属地的查询效果优化

1.文本改变的监听  addTextChangedListener(new TextWatcher(){}）

ed_phone.addTextChangedListener(new TextWatcher() {/** * 当文本发生变化的时候回调 */@Overridepublic void onTextChanged(CharSequence s, int start, int before, int count) {if(s!= null&&s.length()>=3){//查询数据库，并且显示结果String address = NumberAddressQueryUtils.queryNumber(s.toString());result.setText(address);}}/** * 当文本发生变化之前回调 */@Overridepublic void beforeTextChanged(CharSequence s, int start, int count,int after) {// TODO Auto-generated method stub}/** * 当文本发生变化之后回调 */@Overridepublic void afterTextChanged(Editable s) {// TODO Auto-generated method stub}});

5.输入框抖动和振动效果

 ----------抖动----------

1.在res/anim下创建两个xml文件

   shake.xml

<?xml version="1.0" encoding="utf-8"?><translate xmlns:android="http://schemas.android.com/apk/res/android"    android:duration="1000"    android:fromXDelta="0"    android:interpolator="@anim/cycle_7"    android:toXDelta="10" />

  cycle_7.xml

<?xml version="1.0" encoding="utf-8"?><cycleInterpolator xmlns:android="http://schemas.android.com/apk/res/android"    android:cycles="7" />

2.使用

Animation shake = AnimationUtils.loadAnimation(this, R.anim.shake); et.startAnimation(shake);

----------振动---------

1.振动权限

<uses-permission android:name="android.permission.VIBRATE"/>

2.代码

/** * 系统提供的振动服务 */private Vibrator vibrator; vibrator = (Vibrator) getSystemService(VIBRATOR_SERVICE);   //初始化 //当电话号码为空的时候，就去振动手机提醒用户//vibrator.vibrate(2000);  //振动毫秒数long[] pattern = {200,200,300,300,1000,2000};//振动规律，动停动停//-1不重复 0循环振动 1； vibrator.vibrate(pattern, -1);

6.来电号码归属地的显示

1.创建后台监听来电服务

2.权限

<uses-permission android:name="android.permission.READ_PHONE_STATE" /> 

3.在功能清单中注册服务<service>

4.监听电话状态----(在服务中监听)

private TelephonyManager tm;private MyListenerPhone listenerPhone;  //监听器,监听来电private OutCallReceiver receiver;       //接收去电广播// 服务里面的内部类//广播接收者的生命周期和服务一样class OutCallReceiver extends BroadcastReceiver {@Overridepublic void onReceive(Context context, Intent intent) {// 这就是我们拿到的播出去的电话号码String phone = getResultData();// 查询数据库String address = NumberAddressQueryUtils.queryNumber(phone); Toast.makeText(context, address, 1).show();}}      //监听器监听来电      private class MyListenerPhone extends PhoneStateListener {@Overridepublic void onCallStateChanged(int state, String incomingNumber) {// state：状态，incomingNumber：来电号码super.onCallStateChanged(state, incomingNumber);switch (state) {case TelephonyManager.CALL_STATE_RINGING:       // 来电铃声响起// 查询数据库的操作String address = NumberAddressQueryUtils.queryNumber(incomingNumber);  Toast.makeText(getApplicationContext(), address, 1).show();break;case TelephonyManager.CALL_STATE_IDLE://电话的空闲状态：挂电话、来电拒绝//把这个View移除if(view != null ){wm.removeView(view);}break;default:break;}}}                //使用          public void onCreat(){                tm = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);                // 监听来电        listenerPhone = new MyListenerPhone();tm.listen(listenerPhone, PhoneStateListener.LISTEN_CALL_STATE);//监听电话状态                //用代码去注册广播接收者receiver = new OutCallReceiver();IntentFilter filter = new IntentFilter();filter.addAction("android.intent.action.NEW_OUTGOING_CALL");registerReceiver(receiver, filter);              }public void onDestroy() {// TODO Auto-generated method stubsuper.onDestroy();// 取消监听来电tm.listen(listenerPhone, PhoneStateListener.LISTEN_NONE);listenerPhone = null;//用代码取消注册广播接收者unregisterReceiver(receiver);receiver = null;        }

 

 10.自定义吐司

1.吐司的布局文件--(address_show.xml)

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:orientation="horizontal"    android:gravity="center_vertical"     >    <ImageView        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:src="@android:drawable/ic_menu_call" />    <TextView        android:textColor="#000000"        android:id="@+id/tv_address"        android:textSize="22sp"        android:text="号码归属地"        android:layout_width="wrap_content"        android:layout_height="wrap_content" /></LinearLayout>

2.自定义吐司

 

/** * 窗体管理者 */private WindowManager wm;        private View view;//实例化窗体wm = (WindowManager) getSystemService(WINDOW_SERVICE);                /** * 自定义土司 * @param address */public void myToast(String address) {     view =   View.inflate(this, R.layout.address_show, null);    TextView textview  = (TextView) view.findViewById(R.id.tv_address);        //"半透明","活力橙","卫士蓝","金属灰","苹果绿"    int [] ids = {R.drawable.call_locate_white,R.drawable.call_locate_orange,R.drawable.call_locate_blue    ,R.drawable.call_locate_gray,R.drawable.call_locate_green};    SharedPreferences sp = getSharedPreferences("config", MODE_PRIVATE);    view.setBackgroundResource(ids[sp.getInt("which", 0)]);   //设置背景    textview.setText(address);         //窗体的参数就设置好了         WindowManager.LayoutParams params = new WindowManager.LayoutParams();          params.height = WindowManager.LayoutParams.WRAP_CONTENT;//高度         params.width = WindowManager.LayoutParams.WRAP_CONTENT; //宽度                  params.flags = WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE //不可以有焦点                 | WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE      //不可以触摸                 | WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON;    //当吐司弹出时，不可以锁屏         params.format = PixelFormat.TRANSLUCENT;                     //半透明         params.type = WindowManager.LayoutParams.TYPE_TOAST;wm.addView(view, params);}      //使用      myToast(address);    //停用吐司   if(view!=null){    wm.remove(View)    }
