Android項目實現(xiàn)黑名單攔截效果

更新時間：2016年10月24日 10:54:33 作者：ganchuanpu

本篇文章主要介紹了Android項目實現(xiàn)黑名單攔截效果，可以根據(jù)白名單或者黑名單攔截,測試可以攔截電話,有需要的朋友可以了解一下。

本文實例講述了Android編程中黑名單的實現(xiàn)方法。分享給大家供大家參考，具體如下：

1,黑名單數(shù)據(jù)庫創(chuàng)建

三個字段(_id 自增長字段 phone 黑名單號碼 mode 攔截類型)

創(chuàng)建表的sql語句

create table blacknumber (_id integer primary key autoincrement , phone varchar(20), mode varchar(5));

結(jié)合項目,去創(chuàng)建數(shù)據(jù)庫,以及相應(yīng)的表

2.BlackNumberDao

BlackNumberDao單例模式

package com.itheima.mobilesafe74.db.dao;

import java.util.ArrayList;
import java.util.List;

import android.content.ContentValues;
import android.content.Context;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;

import com.itheima.mobilesafe74.db.BlackNumberOpenHelper;
import com.itheima.mobilesafe74.db.domain.BlackNumberInfo;

public class BlackNumberDao {
  private BlackNumberOpenHelper blackNumberOpenHelper;
  //BlackNumberDao單例模式
  //1,私有化構(gòu)造方法
  private BlackNumberDao(Context context){
    //創(chuàng)建數(shù)據(jù)庫已經(jīng)其表機構(gòu)
    blackNumberOpenHelper = new BlackNumberOpenHelper(context);
  }
  //2,聲明一個當(dāng)前類的對象
  private static BlackNumberDao blackNumberDao = null;
  //3,提供一個靜態(tài)方法,如果當(dāng)前類的對象為空,創(chuàng)建一個新的
  public static BlackNumberDao getInstance(Context context){
    if(blackNumberDao == null){
      blackNumberDao = new BlackNumberDao(context);
    }
    return blackNumberDao;
  }
  
  /**增加一個條目
   * @param phone  攔截的電話號碼
   * @param mode  攔截類型(1:短信  2:電話  3:攔截所有(短信+電話))
   */
  public void insert(String phone,String mode){
    //1,開啟數(shù)據(jù)庫,準備做寫入操作
    SQLiteDatabase db = blackNumberOpenHelper.getWritableDatabase();

    ContentValues values = new ContentValues();
    values.put("phone", phone);
    values.put("mode", mode);
    db.insert("blacknumber", null, values);
    
    db.close();
  }
  
  /**從數(shù)據(jù)庫中刪除一條電話號碼
   * @param phone  刪除電話號碼
   */
  public void delete(String phone){
    SQLiteDatabase db = blackNumberOpenHelper.getWritableDatabase();

    db.delete("blacknumber", "phone = ?", new String[]{phone});
    
    db.close();
  }
  
  /**
   * 根據(jù)電話號碼去,更新攔截模式
   * @param phone  更新攔截模式的電話號碼
   * @param mode  要更新為的模式(1:短信  2:電話  3:攔截所有(短信+電話)
   */
  public void update(String phone,String mode){
    SQLiteDatabase db = blackNumberOpenHelper.getWritableDatabase();

    ContentValues contentValues = new ContentValues();
    contentValues.put("mode", mode);
    
    db.update("blacknumber", contentValues, "phone = ?", new String[]{phone});
    
    db.close();
  }
  
  /**
   * @return  查詢到數(shù)據(jù)庫中所有的號碼以及攔截類型所在的集合
   */
  public List<BlackNumberInfo> findAll(){
    SQLiteDatabase db = blackNumberOpenHelper.getWritableDatabase();

    Cursor cursor = db.query("blacknumber", new String[]{"phone","mode"}, null, null, null, null, "_id desc");
    List<BlackNumberInfo> blackNumberList = new ArrayList<BlackNumberInfo>();
    while(cursor.moveToNext()){
      BlackNumberInfo blackNumberInfo = new BlackNumberInfo();
      blackNumberInfo.phone = cursor.getString(0);
      blackNumberInfo.mode = cursor.getString(1);
      blackNumberList.add(blackNumberInfo);
    }
    cursor.close();
    db.close();
    
    return blackNumberList;
  }
  
  /**
   * 每次查詢20條數(shù)據(jù)
   * @param index  查詢的索引值
   */
  public List<BlackNumberInfo> find(int index){
    SQLiteDatabase db = blackNumberOpenHelper.getWritableDatabase();

    Cursor cursor = db.rawQuery("select phone,mode from blacknumber order by _id desc limit ?,20;", new String[]{index+""});
    
    List<BlackNumberInfo> blackNumberList = new ArrayList<BlackNumberInfo>();
    while(cursor.moveToNext()){
      BlackNumberInfo blackNumberInfo = new BlackNumberInfo();
      blackNumberInfo.phone = cursor.getString(0);
      blackNumberInfo.mode = cursor.getString(1);
      blackNumberList.add(blackNumberInfo);
    }
    cursor.close();
    db.close();
    
    return blackNumberList;
  }
  
  /**
   * @return  數(shù)據(jù)庫中數(shù)據(jù)的總條目個數(shù),返回0代表沒有數(shù)據(jù)或異常
   */
  public int getCount(){
    SQLiteDatabase db = blackNumberOpenHelper.getWritableDatabase();
    int count = 0;
    Cursor cursor = db.rawQuery("select count(*) from blacknumber;", null);
    if(cursor.moveToNext()){
      count = cursor.getInt(0);
    }
    
    cursor.close();
    db.close();
    return count;
  }
  
  /**
   * @param phone  作為查詢條件的電話號碼
   * @return  傳入電話號碼的攔截模式  1:短信  2:電話  3:所有  0:沒有此條數(shù)據(jù)
   */
  public int getMode(String phone){
    SQLiteDatabase db = blackNumberOpenHelper.getWritableDatabase();
    int mode = 0;
    Cursor cursor = db.query("blacknumber", new String[]{"mode"}, "phone = ?", new String[]{phone}, null, null,null);
    if(cursor.moveToNext()){
      mode = cursor.getInt(0);
    }
    
    cursor.close();
    db.close();
    return mode;
  }
}

3,加載更多的觸發(fā)條件

監(jiān)聽狀態(tài)改變
滾動到最底部,最后一個listView的條目可見
滾動狀態(tài)發(fā)生改變滾動------>停止(空閑)

加載下一頁數(shù)據(jù)完成后,需要添加到上一頁數(shù)據(jù)的最后面

//監(jiān)聽其滾動狀態(tài)
lv_blacknumber.setOnScrollListener(new OnScrollListener() {
  //滾動過程中,狀態(tài)發(fā)生改變調(diào)用方法()
  @Override
  public void onScrollStateChanged(AbsListView view, int scrollState) {
//       OnScrollListener.SCROLL_STATE_FLING 飛速滾動
//       OnScrollListener.SCROLL_STATE_IDLE  空閑狀態(tài)
//       OnScrollListener.SCROLL_STATE_TOUCH_SCROLL 拿手觸摸著去滾動狀態(tài)
     
    if(mBlackNumberList!=null){
      //條件一:滾動到停止?fàn)顟B(tài)
      //條件二:最后一個條目可見(最后一個條目的索引值>=數(shù)據(jù)適配器中集合的總條目個數(shù)-1)
      if(scrollState == OnScrollListener.SCROLL_STATE_IDLE
          && lv_blacknumber.getLastVisiblePosition()>=mBlackNumberList.size()-1
          && !mIsLoad){
        /*mIsLoad防止重復(fù)加載的變量
        如果當(dāng)前正在加載mIsLoad就會為true,本次加載完畢后,再將mIsLoad改為false
        如果下一次加載需要去做執(zhí)行的時候,會判斷上訴mIsLoad變量,是否為false,如果為true,就需要等待上一次加載完成,將其值
        改為false后再去加載*/
         
        //如果條目總數(shù)大于集合大小的時,才可以去繼續(xù)加載更多
        if(mCount>mBlackNumberList.size()){
          //加載下一頁數(shù)據(jù)
          new Thread(){
            public void run() {
              //1,獲取操作黑名單數(shù)據(jù)庫的對象
              mDao = BlackNumberDao.getInstance(getApplicationContext());
              //2,查詢部分數(shù)據(jù)
              List<BlackNumberInfo> moreData = mDao.find(mBlackNumberList.size());
              //3,添加下一頁數(shù)據(jù)的過程
              mBlackNumberList.addAll(moreData);
              //4,通知數(shù)據(jù)適配器刷新
              mHandler.sendEmptyMessage(0);
            }
          }.start();
        }
      }
    }
     
  }
   
  //滾動過程中調(diào)用方法
  @Override
  public void onScroll(AbsListView view, int firstVisibleItem,
      int visibleItemCount, int totalItemCount) {
     
  }
});

4.攔截短信

短信在接受的時候,廣播發(fā)送,監(jiān)聽廣播接受者,攔截短信(有序)
將廣播的優(yōu)先級級別提高到最高 (1000)

5.攔截電話

有電話撥入,處于響鈴狀態(tài),響鈴狀態(tài)通過代碼去掛斷電話(aidl,反射),攔截電話
掛斷電話號碼的方法,放置在了aidl文件中名稱為endCall

在此處去查看TelePhoneManager源碼,去查找獲取ITelephony對象的方法

ServiceManager此類android對開發(fā)者隱藏,所以不能去直接調(diào)用其方法,所以需要反射調(diào)用

ITelephony.Stub.asInterface(ServiceManager.getService(Context.TELEPHONY_SERVICE));

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

//1,獲取ServiceManager字節(jié)碼文件
Class<?> clazz = Class.forName("android.os.ServiceManager");
//2,獲取方法
Method method = clazz.getMethod("getService", String.class);
//3,反射調(diào)用此方法
IBinder iBinder = (IBinder) method.invoke(null, Context.TELEPHONY_SERVICE);
//4,調(diào)用獲取aidl文件對象方法
ITelephony iTelephony = ITelephony.Stub.asInterface(iBinder);
//5,調(diào)用在aidl中隱藏的endCall方法

BlackNumberService

iTelephony.endCall();
