概述

下面先来讲下Android四大组件在demo中的应用:

Activity:这个大家肯定是比较熟悉的,也是大家比较常用的。主要是用来加载页面和一些操作。

Service:我们的Service会一直在后台运行,如果是黑名单中的号码,将会直接拦截。有两种启动方式,这里不具体分析。

ContentProvider:内容提供者,它的作用主要是对应用之间 的数据操作提供接口,不懂的可以看下我的这篇BLOG:
http://blog.csdn.net/Simon_Crystin/article/details/68517050
这这个demo中的应用主要是用来对本地数据库进行操作,这里本来是是不需要用到ContentProvider,但是基于某种原因,我这里用了。这个是不需要纠结的。

BroadcastReceiver:这里主要是在开机时发送一个广播,在接收广播的时候开启一个服务。对广播接收者不熟悉的也可以看下这片Blog:
http://blog.csdn.net/Simon_Crystin/article/details/68062838

除了这些:里面还涉及了许多知识点,比如:
1:正则表达式的用法,用来匹配手机号码;
2:aidl的使用,用来拦截来电;
3:各种权限的使用;
4:adapter的使用;
5:dialog的自定义;
6:Toast的自定义等等,还有许多小技巧。

实现

1.添加黑名单。
2.判断如果是黑名单,就对其拦截。

添加黑名单:

往数据库里面添加黑名单,手机号码,用的是ContentProvider进行添加的(当然,这里是完全没有必要用这个的)

第一步:
新建一个MyContentProvider继承自ContentProvider,并重写其中的方法:

package com.wind.safecall.contentprovider;

import android.content.ContentProvider;
import android.content.ContentUris;
import android.content.ContentValues;
import android.content.Context;
import android.content.UriMatcher;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;
import android.net.Uri;
import android.support.annotation.NonNull;
import android.support.annotation.Nullable;

/**
 * Created by zhangcong on 2017/4/8.
 */

public class MyContentProvider extends ContentProvider {
    private MyOpenHelper myOpenHelper;
    private String DB_name="blackname";//数据库名
    private String Table_name="blacknametable";//数据表名
    private SQLiteDatabase sqLiteDatabase;
    private static UriMatcher uriMatcher;
    public static  final String AUTHORITY="blacknum";
    public static final  Uri uri =Uri.parse("content://blacknum/path_simon");

    // 注册该内容提供者匹配的uri
    static {
        uriMatcher=new UriMatcher(UriMatcher.NO_MATCH);//Creates the root node of the URI tree.
        uriMatcher.addURI(AUTHORITY,"path_simon",1);// 代表当前表中的所有的记录,第三个参数必须为正数
        uriMatcher.addURI(AUTHORITY,"path_simon/1",2);// 代表当前表中的某条特定的记录,记录id便是#处得数字
    }
    //数据表列名映射
    private static  final  String blacknum="blacknum";
    private static final String _id = "id";

    @Override
    public boolean onCreate() {
        try {
            myOpenHelper=new MyOpenHelper(getContext(),DB_name,null,1);
        }
        catch (Exception e)
        {
            return  false;
        }
        return true;
    }

    @Nullable
    @Override
    public Cursor query(@NonNull Uri uri, @Nullable String[] projection, @Nullable String selection, @Nullable String[] selectionArgs, @Nullable String sortOrder) {
        Cursor cursor = null;
        sqLiteDatabase = myOpenHelper.getReadableDatabase();
        int code = uriMatcher.match(uri);//addURI()传的第三个参数
        switch (code) {
            case 1:
                cursor = sqLiteDatabase.query(Table_name, projection, selection,
                        selectionArgs, null, null, sortOrder);
                break;
            case 2:
                // 从uri中解析出ID
                long id = ContentUris.parseId(uri);
                selection = (selection == null || "".equals(selection.trim())) ? _id
                        + "=" + id
                        : selection + " and " + _id + "=" + id;
                cursor = sqLiteDatabase.query(Table_name, projection, selection,
                        selectionArgs, null, null, sortOrder);
                break;
            default:
                throw new IllegalArgumentException("参数错误");
        }

        return cursor;
    }

    @Nullable
    @Override
    public String getType(@NonNull Uri uri) {
        return null;
    }

    @Nullable
    @Override
    public Uri insert(@NonNull Uri uri, @Nullable ContentValues values) {
        sqLiteDatabase=myOpenHelper.getWritableDatabase();
        sqLiteDatabase = myOpenHelper.getWritableDatabase();
        int code = uriMatcher.match(uri);//前面addURI传的第三个参数
        switch (code) {
            case 1:
                sqLiteDatabase.insert(Table_name, blacknum, values);
                break;
            case 2:
                long id = sqLiteDatabase.insert(Table_name, blacknum, values);
                // withAppendId将id添加到uri的最后
                ContentUris.withAppendedId(uri, id);
                break;
            default:
                throw new IllegalArgumentException("异常参数");
        }

        return uri;
    }

    @Override
    public int delete(@NonNull Uri uri, @Nullable String selection, @Nullable String[] selectionArgs) {
        return 0;
    }

    @Override
    public int update(@NonNull Uri uri, @Nullable ContentValues values, @Nullable String selection, @Nullable String[] selectionArgs) {
        return 0;
    }

    private class MyOpenHelper extends SQLiteOpenHelper
    {

        public MyOpenHelper(Context context, String name, SQLiteDatabase.CursorFactory factory, int version) {
            super(context, name, factory, version);
        }

        @Override
        public void onCreate(SQLiteDatabase db) {
            /**
             * 官方解释
             * Called when the database is created for the first time. This is where the
             * creation of tables and the initial population of the tables should happen.
             *
             * @param db The database.
             */
            String sql = " create table if not exists " + Table_name
                    + "(blacknum  varchar(20),id INTEGER)";
            db.execSQL(sql);
        }

        @Override
        public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {

        }
    }
}

第二步:在你的监听事件下执行这个方法:

 private void insertData(String blacknum) {
        ContentValues contentValues=new ContentValues();
        contentValues.put("blacknum",blacknum);//与数据库字段对应,第二个参数是你添加的给名单
        Uri uri=getContentResolver().insert(MyContentProvider.uri,contentValues);
        Utils.showToast(uri.toString(),MainActivity.this);

    }

第三步:查询你所添加的黑名单:
这里分了两个步骤:
查询黑名单和显示黑名单:

查询黑名单

private void queryBlackNum() {
        String array[]={"blacknum"};
        Cursor cursor=getContentResolver().query(MyContentProvider.uri,array,null,null,null);
        int blacknumindex=cursor.getColumnIndex("blacknum");
        Log.i(">>>",blacknumindex+"");
        cursor.moveToFirst();
        ArrayList list=new ArrayList<>();
        while (!cursor.isAfterLast())
        {
            String blacknum=cursor.getString(blacknumindex);
            list.add(blacknum);
            cursor.moveToNext();
            Log.i(">>>",">>>>");
            Log.i("Simon",list.toString());
        }
        Intent intent=new Intent(MainActivity.this,BlackNumActivity.class);
        intent.putStringArrayListExtra("list", list);
//        Bundle bundle=new Bundle();
//        bundle.putSerializable("list", (Serializable) list);
//        intent.putExtras(bundle);
        startActivity(intent);


    }

在另一个Activity显示黑名单:

package com.wind.safecall.activity;

import android.app.Activity;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.util.Log;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.TextView;

import com.wind.safecall.R;

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


/**
 * Created by zhangcong on 2017/4/10.
 */

public class BlackNumActivity extends Activity{
    private TextView activitytitle;
    private TextView back;
    private StringBuffer sb;
    private ListView listview;
    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_black_num);
        activitytitle= (TextView) findViewById(R.id.tv_activity_toolbar_center);
        activitytitle.setText("黑名单");

        listview= (ListView) findViewById(R.id.lv_black_num);

        back= (TextView) findViewById(R.id.tv_back);
        back.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                finish();
            }
        });
        showBlackNum();
    }

    private void showBlackNum() {
        ArrayList list = this.getIntent().getStringArrayListExtra("list");
        Log.i(">>>>>", list.toString());
        if (list != null) {
            listview.setAdapter(new ArrayAdapter<>(BlackNumActivity.this, R.layout.item_black_num, R.id.tv_black_num, list));
        }
    }
}

到这里,黑名单就添加完成。

接下来就是对其进行拦截了:
拦截黑名单来电:

第一步:新建一个BlackNumService继承自Service,在这里面判断是不是黑名单,是的话对其拦截:
这里需要补充一点的是:由于我们是直接拦截的来电,相当于是跨进程间的通信,这个时候aidl就登场了,好在Android有这些接口:
因为下面的代码会调用这些接口,所以我们提交准备好:

1.在根目录新建一个android.telephony的包,在里面新建一个aidl文件,命名为NeighboringCellInfo;
里面的内容为:

// NeighboringCellInfo.aidl
package android.telephony;

// Declare any non-default types here with import statements


parcelable NeighboringCellInfo;

2.在根目录下新建一个com.android.internal.telephony的包,在里面新建一个aidl文件,命名为ITelephony;里面的内容为:

package com.android.internal.telephony;
interface ITelephony{
    boolean endCall();
    void answerRingingCall();
}

这里的包名和文件名一定要一致,通过包名识别来电的,再进行通信的

package com.wind.safecall.service;

import android.app.Notification;
import android.app.NotificationManager;
import android.app.Service;
import android.content.Context;
import android.content.Intent;
import android.database.Cursor;
import android.net.Uri;
import android.os.IBinder;
import android.support.annotation.Nullable;
import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;
import android.util.Log;

import com.android.internal.telephony.ITelephony;
import com.wind.safecall.contentprovider.MyContentProvider;

import org.w3c.dom.ls.LSInput;

public class BlackNumService extends Service {
    private TelephonyManager tm;
    private MyPhoneStateListener listener;
    private NotificationManager nm;
    @Override
    public void onCreate() {
        super.onCreate();
        tm= (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
        listener=new MyPhoneStateListener();
        tm.listen(listener,PhoneStateListener.LISTEN_CALL_STATE);
       // nm= (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    }
    private final class MyPhoneStateListener extends PhoneStateListener{
        //private long startTime = 0;
        @Override
        public void onCallStateChanged(int state, String incomingNumber) {
            // TODO Auto-generated method stub
            super.onCallStateChanged(state, incomingNumber);
            switch (state) {
                case TelephonyManager.CALL_STATE_RINGING:
                    String array[]={"blacknum"};
                    Cursor cursor=getContentResolver().query(MyContentProvider.uri,array,null,null,null);
                    int blacknumindex=cursor.getColumnIndex("blacknum");
                    Log.i(">>>",blacknumindex+"");
                    cursor.moveToFirst();
                    ArrayList list=new ArrayList<>();
                    while (!cursor.isAfterLast())
                    {
                        String blacknum=cursor.getString(blacknumindex);
                        list.add(blacknum);
                        cursor.moveToNext();
                        Log.i(">>>",">>>>");
                        Log.i("Simon",list.toString());
                    }
                    if (list!=null&&list.contains(incomingNumber))
                    {
                        endCall();
                        return;
                    }
                    //判断来电黑名单是否开启
//                    boolean isblackstart = sp.getBoolean("isblacknumber", false);
//                    if(isblackstart){
//                        boolean isBlackNumber = blackNumberDao.isBlackNumber(incomingNumber);
//                        if(isBlackNumber){
//
//                        }


                    //startTime = System.currentTimeMillis();

                    break;
                case TelephonyManager.CALL_STATE_OFFHOOK:
                    break;
                case TelephonyManager.CALL_STATE_IDLE:
                    break;

                default:
                    break;
            }
        }

    }
    //挂断电话
    private void endCall(){
        try {
            Class clazz = Class.forName("android.os.ServiceManager");
            Method method = clazz.getMethod("getService", String.class);
            IBinder ibinder = (IBinder) method.invoke(null, Context.TELEPHONY_SERVICE);
            ITelephony iTelephony = ITelephony.Stub.asInterface(ibinder);
            iTelephony.endCall();

        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
    @Nullable
    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }
}

第二步:在广播中或者应用中开启服务:

1.在应用中开启服务:

 /*
    启动服务
     */
    private void stService() {
        Intent intent=new Intent(MainActivity.this, BlackNumService.class);
        startService(intent);
    }

你可以在mainactivity中的oncreate方法中调用这个方法,只要这个进程不被杀死,这个服务也就一致存在,这是startService的性质。

2.在开机广播中开启服务:有些手机是接收不到广播的:

需要新建一个BootCompletedReceiver继承自BroadcastReceiver:

package com.wind.safecall.broadcastreceiver;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;

import com.wind.safecall.service.BlackNumService;


/**
 * Created by zhangcong on 2017/4/10.
 */

public class BootCompletedReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent){
        Log.i(">>>>>>>>","已经开机");
        Intent intent1=new Intent(context, BlackNumService.class);
        context.startService(intent1);
    }
}

这样,整个流程就结束了,最后贴出所有的权限和注册:


<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.wind.safecall">

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

    <uses-permission android:name="android.permission.CALL_PHONE">uses-permission>
    <permission android:name="blacknum.permission"
        android:protectionLevel="normal"/>
    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        
        <receiver android:name=".broadcastreceiver.BootCompletedReceiver">

                <category android:name="android.intent.category.HOME" />
            intent-filter>
        receiver>
        <service android:name=".service.BlackNumService"/>
        <provider

            android:name=".contentprovider.MyContentProvider"

            />
        <activity
            android:name=".activity.MainActivity"
            android:screenOrientation="portrait">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />

        <activity android:name=".activity.BlackNumActivity"
            android:screenOrientation="portrait"/>
    application>

manifest>
