Android 手机卫士7--黑名单拦截
1,黑名单数据库创建
三个字段(_id 自增长字段 phone 黑名单号码 mode 拦截类型)
创建表的sql语句
create table blacknumber (_id integer primary key autoincrement , phone varchar(20), mode varchar(5));
结合项目,去创建数据库,以及相应的表
2.BlackNumberDao
BlackNumberDao单例模式
1 package com.itheima.mobilesafe74.db.dao; 2 3 import java.util.ArrayList; 4 import java.util.List; 5 6 import android.content.ContentValues; 7 import android.content.Context; 8 import android.database.Cursor; 9 import android.database.sqlite.SQLiteDatabase; 10 11 import com.itheima.mobilesafe74.db.BlackNumberOpenHelper; 12 import com.itheima.mobilesafe74.db.domain.BlackNumberInfo; 13 14 public class BlackNumberDao { 15 private BlackNumberOpenHelper blackNumberOpenHelper; 16 //BlackNumberDao单例模式 17 //1,私有化构造方法 18 private BlackNumberDao(Context context){ 19 //创建数据库已经其表机构 20 blackNumberOpenHelper = new BlackNumberOpenHelper(context); 21 } 22 //2,声明一个当前类的对象 23 private static BlackNumberDao blackNumberDao = null; 24 //3,提供一个静态方法,如果当前类的对象为空,创建一个新的 25 public static BlackNumberDao getInstance(Context context){ 26 if(blackNumberDao == null){ 27 blackNumberDao = new BlackNumberDao(context); 28 } 29 return blackNumberDao; 30 } 31 32 /**增加一个条目 33 * @param phone 拦截的电话号码 34 * @param mode 拦截类型(1:短信 2:电话 3:拦截所有(短信+电话)) 35 */ 36 public void insert(String phone,String mode){ 37 //1,开启数据库,准备做写入操作 38 SQLiteDatabase db = blackNumberOpenHelper.getWritableDatabase(); 39 40 ContentValues values = new ContentValues(); 41 values.put("phone", phone); 42 values.put("mode", mode); 43 db.insert("blacknumber", null, values); 44 45 db.close(); 46 } 47 48 /**从数据库中删除一条电话号码 49 * @param phone 删除电话号码 50 */ 51 public void delete(String phone){ 52 SQLiteDatabase db = blackNumberOpenHelper.getWritableDatabase(); 53 54 db.delete("blacknumber", "phone = ?", new String[]{phone}); 55 56 db.close(); 57 } 58 59 /** 60 * 根据电话号码去,更新拦截模式 61 * @param phone 更新拦截模式的电话号码 62 * @param mode 要更新为的模式(1:短信 2:电话 3:拦截所有(短信+电话) 63 */ 64 public void update(String phone,String mode){ 65 SQLiteDatabase db = blackNumberOpenHelper.getWritableDatabase(); 66 67 ContentValues contentValues = new ContentValues(); 68 contentValues.put("mode", mode); 69 70 db.update("blacknumber", contentValues, "phone = ?", new String[]{phone}); 71 72 db.close(); 73 } 74 75 /** 76 * @return 查询到数据库中所有的号码以及拦截类型所在的集合 77 */ 78 public List<BlackNumberInfo> findAll(){ 79 SQLiteDatabase db = blackNumberOpenHelper.getWritableDatabase(); 80 81 Cursor cursor = db.query("blacknumber", new String[]{"phone","mode"}, null, null, null, null, "_id desc"); 82 List<BlackNumberInfo> blackNumberList = new ArrayList<BlackNumberInfo>(); 83 while(cursor.moveToNext()){ 84 BlackNumberInfo blackNumberInfo = new BlackNumberInfo(); 85 blackNumberInfo.phone = cursor.getString(0); 86 blackNumberInfo.mode = cursor.getString(1); 87 blackNumberList.add(blackNumberInfo); 88 } 89 cursor.close(); 90 db.close(); 91 92 return blackNumberList; 93 } 94 95 /** 96 * 每次查询20条数据 97 * @param index 查询的索引值 98 */ 99 public List<BlackNumberInfo> find(int index){ 100 SQLiteDatabase db = blackNumberOpenHelper.getWritableDatabase(); 101 102 Cursor cursor = db.rawQuery("select phone,mode from blacknumber order by _id desc limit ?,20;", new String[]{index+""}); 103 104 List<BlackNumberInfo> blackNumberList = new ArrayList<BlackNumberInfo>(); 105 while(cursor.moveToNext()){ 106 BlackNumberInfo blackNumberInfo = new BlackNumberInfo(); 107 blackNumberInfo.phone = cursor.getString(0); 108 blackNumberInfo.mode = cursor.getString(1); 109 blackNumberList.add(blackNumberInfo); 110 } 111 cursor.close(); 112 db.close(); 113 114 return blackNumberList; 115 } 116 117 /** 118 * @return 数据库中数据的总条目个数,返回0代表没有数据或异常 119 */ 120 public int getCount(){ 121 SQLiteDatabase db = blackNumberOpenHelper.getWritableDatabase(); 122 int count = 0; 123 Cursor cursor = db.rawQuery("select count(*) from blacknumber;", null); 124 if(cursor.moveToNext()){ 125 count = cursor.getInt(0); 126 } 127 128 cursor.close(); 129 db.close(); 130 return count; 131 } 132 133 /** 134 * @param phone 作为查询条件的电话号码 135 * @return 传入电话号码的拦截模式 1:短信 2:电话 3:所有 0:没有此条数据 136 */ 137 public int getMode(String phone){ 138 SQLiteDatabase db = blackNumberOpenHelper.getWritableDatabase(); 139 int mode = 0; 140 Cursor cursor = db.query("blacknumber", new String[]{"mode"}, "phone = ?", new String[]{phone}, null, null,null); 141 if(cursor.moveToNext()){ 142 mode = cursor.getInt(0); 143 } 144 145 cursor.close(); 146 db.close(); 147 return mode; 148 } 149 }
3,加载更多的触发条件
1.监听状态改变
2.滚动到最底部,最后一个listView的条目可见
3.滚动状态发生改变 滚动------>停止(空闲)
加载下一页数据完成后,需要添加到上一页数据的最后面 20 40 60 80 100
//监听其滚动状态 lv_blacknumber.setOnScrollListener(new OnScrollListener() { //滚动过程中,状态发生改变调用方法() @Override public void onScrollStateChanged(AbsListView view, int scrollState) { // OnScrollListener.SCROLL_STATE_FLING 飞速滚动 // OnScrollListener.SCROLL_STATE_IDLE 空闲状态 // OnScrollListener.SCROLL_STATE_TOUCH_SCROLL 拿手触摸着去滚动状态 if(mBlackNumberList!=null){ //条件一:滚动到停止状态 //条件二:最后一个条目可见(最后一个条目的索引值>=数据适配器中集合的总条目个数-1) if(scrollState == OnScrollListener.SCROLL_STATE_IDLE && lv_blacknumber.getLastVisiblePosition()>=mBlackNumberList.size()-1 && !mIsLoad){ /*mIsLoad防止重复加载的变量 如果当前正在加载mIsLoad就会为true,本次加载完毕后,再将mIsLoad改为false 如果下一次加载需要去做执行的时候,会判断上诉mIsLoad变量,是否为false,如果为true,就需要等待上一次加载完成,将其值 改为false后再去加载*/ //如果条目总数大于集合大小的时,才可以去继续加载更多 if(mCount>mBlackNumberList.size()){ //加载下一页数据 new Thread(){ public void run() { //1,获取操作黑名单数据库的对象 mDao = BlackNumberDao.getInstance(getApplicationContext()); //2,查询部分数据 List<BlackNumberInfo> moreData = http://www.mamicode.com/mDao.find(mBlackNumberList.size());>
4.拦截短信
短信在接受的时候,广播发送,监听广播接受者,拦截短信(有序)
将广播的优先级级别提高到最高 (1000)
5.拦截电话
有电话拨入,处于响铃状态,响铃状态通过代码去挂断电话(aidl,反射),拦截电话
挂断电话号码的方法,放置在了aidl文件中名称为endCall
在此处去查看TelePhoneManager源码,去查找获取ITelephony对象的方法
ServiceManager此类android对开发者隐藏,所以不能去直接调用其方法,所以需要反射调用
ITelephony.Stub.asInterface(ServiceManager.getService(Context.TELEPHONY_SERVICE));
<uses-permission android:name="android.permission.CALL_PHONE"/>
//1,获取ServiceManager字节码文件
Class<?> clazz = Class.forName("android.os.ServiceManager");
//2,获取方法
Method method = clazz.getMethod("getService", String.class);
//3,反射调用此方法
IBinder iBinder = (IBinder) method.invoke(null, Context.TELEPHONY_SERVICE);
//4,调用获取aidl文件对象方法
ITelephony iTelephony = ITelephony.Stub.asInterface(iBinder);
//5,调用在aidl中隐藏的endCall方法
iTelephony.endCall();
