Android 實現電話攔截及攔截提示音功能的開發_Android

  本文所講的內容是在Android系統中如何寫程式進行電話攔截，並發出攔截提示音提醒使用者，可以說此功能還是比較實用的。

       1、電話攔截

       這個功能大家可能都知道了，就是利用反射原理調用ITelephony的隱藏方法來實現。

       2、攔截後提示忙音/空號/已關機/已停機

       這個功能其實是要用到MMI指令，具體如何設定來電轉接的指定可以參考這裡 http://baike.baidu.com/view/206402.html?fromTaglist。

       在本文中我們會用到“遇忙轉移”的功能。中國移動的設定方式是 **67#電話號碼#，取消方式為 ##67#。”無條件轉移“用21代替67即可。這兩個指令可以直接在手機的撥號介面輸入並撥號測試。ITelephony的endcall方法掛斷電話後，會提示電話忙。如果事前設定好了忙時轉移到一個空號/已關機/已停機的電話號碼，就會提示您撥的電話號碼是空號/已關機/已停機。

       其實大家可以下載 xxx衛士看下，它設定來電拒接模式後，都是會啟動設定MMI指令的介面。然後再去“設定->通話設定->來電轉接”，看看 “佔線時轉接” 設定好的電話號碼，就可以知道空號/已關機/已停機對應的電話號碼是什麼了。

       1、修改一下BLOCKED_NUMBER這個變數值，把它設定為你要測試攔截的電話號碼。

       2、全部功能是在一個Activity裡實現的，所以大家要先運行這個Activity，然後點擊“設定來電轉接”，設定好來電轉接後，不要關閉這個Activity，關了就攔截不了電話了。有心的朋友可以自己去寫一個Service在後台運行攔截功能。

       實現方式1：

       代碼如下：

package net.toeach.android.callforwarding;     import java.lang.reflect.Method;     import android.app.Activity;   import android.content.BroadcastReceiver;   import android.content.Context;   import android.content.Intent;   import android.content.IntentFilter;   import android.media.AudioManager;   import android.net.Uri;   import android.os.Bundle;   import android.os.Handler;   import android.os.Message;   import android.os.RemoteException;   import android.telephony.TelephonyManager;   import android.util.Log;   import android.view.View;   import android.view.View.OnClickListener;     import com.android.internal.telephony.ITelephony;     /**   * 示範如何設定來電轉接，攔截電話（攔截後提示為空白號）的例子   * @author Tony from ToEach.   * @email wan1976@21cn.com   */  public class MainActivity extends Activity {    private static final String TAG = MainActivity.class.getSimpleName();        private final static int OP_REGISTER = 100;    private final static int OP_CANCEL = 200;       private final static String BLOCKED_NUMBER = "1892501xxxx";//要攔截的號碼    //佔線時轉移，這裡13800000000是空號，所以會提示所撥的號碼為空白號     private final String ENABLE_SERVICE = "tel:**67*13800000000%23";     //佔線時轉移     private final String DISABLE_SERVICE = "tel:%23%2367%23";      private IncomingCallReceiver mReceiver;     private ITelephony iTelephony;     private AudioManager mAudioManager;        @Override    public void onCreate(Bundle savedInstanceState) {       super.onCreate(savedInstanceState);       setContentView(R.layout.main);             findViewById(R.id.btnEnable).setOnClickListener(new OnClickListener(){     public void onClick(View v) {        //設定來電轉接        Message message = mHandler.obtainMessage();     message.what = OP_REGISTER;     mHandler.dispatchMessage(message);     }       });             findViewById(R.id.btnDisable).setOnClickListener(new OnClickListener(){     public void onClick(View v) {     //取消來電轉接          Message message = mHandler.obtainMessage();       message.what = OP_CANCEL;       mHandler.dispatchMessage(message);     }       });             mReceiver = new IncomingCallReceiver();    IntentFilter filter = new IntentFilter("android.intent.action.PHONE_STATE");         registerReceiver(mReceiver, filter);// 註冊BroadcastReceiver             mAudioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);             //利用反射擷取隱藏的endcall方法       TelephonyManager telephonyMgr = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);    try {     Method getITelephonyMethod = TelephonyManager.class.getDeclaredMethod("getITelephony", (Class[]) null);     getITelephonyMethod.setAccessible(true);     iTelephony = (ITelephony) getITelephonyMethod.invoke(telephonyMgr, (Object[]) null);      } catch (Exception e) {      e.printStackTrace();      }     }         private Handler mHandler = new Handler() {    public void handleMessage(Message response) {      int what = response.what;      switch(what) {       case OP_REGISTER:{       Intent i = new Intent(Intent.ACTION_CALL);          i.setData(Uri.parse(ENABLE_SERVICE));          startActivity(i);       break;       }       case OP_CANCEL:{       Intent i = new Intent(Intent.ACTION_CALL);          i.setData(Uri.parse(DISABLE_SERVICE));          startActivity(i);       break;       }      }    }    };       private class IncomingCallReceiver extends BroadcastReceiver{    @Override   public void onReceive(Context context, Intent intent) {     String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);        Log.i(TAG, "State: "+ state);            String number = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);        Log.d(TAG, "Incomng Number: " + number);               if(state.equalsIgnoreCase(TelephonyManager.EXTRA_STATE_RINGING)){//電話正在響鈴             if(number.equals(BLOCKED_NUMBER)){//攔截指定的電話號碼         //先靜音處理         mAudioManager.setRingerMode(AudioManager.RINGER_MODE_SILENT);         Log.d(TAG, "Turn ringtone silent");                 try {         //掛斷電話      iTelephony.endCall();      } catch (RemoteException e) {      e.printStackTrace();      }           //再恢複正常鈴聲            mAudioManager.setRingerMode(AudioManager.RINGER_MODE_NORMAL);        }        }    }    }   }  

         AndroidManifest.xml 如下：

<?xml version="1.0" encoding="utf-8"?>  <manifest xmlns:android="http://schemas.android.com/apk/res/android "     package="net.toeach.android.callforwarding"     android:versionCode="1"     android:versionName="1.0">    <application android:icon="@drawable/icon" android:label="@string/app_name">      <activity android:name=".MainActivity"           android:label="@string/app_name">        <intent-filter>          <action android:name="android.intent.action.MAIN" />          <category android:name="android.intent.category.LAUNCHER" />        </intent-filter>      </activity>      </application>    <uses-sdk android:minSdkVersion="8" />        <uses-permission android:name="android.permission.READ_PHONE_STATE"/>    <uses-permission android:name="android.permission.CALL_PHONE"/>    </manifest>

  4、AndroidManifest.xml代碼如下：

<?xml version="1.0" encoding="utf-8"?>  <manifest xmlns:android="http://schemas.android.com/apk/res/android"     package="android.refuseCalling"     android:versionCode="1"     android:versionName="1.0">     <uses-permission android:name="android.permission.READ_PHONE_STATE" />       <uses-permission android:name="android.permission.CALL_PHONE" />       <uses-permission android:name="android.permission.MODIFY_PHONE_STATE" />            <application android:icon="@drawable/icon" android:label="@string/app_name">      <activity android:name=".refuseCalling"           android:label="@string/app_name">        <intent-filter>          <action android:name="android.intent.action.MAIN" />          <category android:name="android.intent.category.LAUNCHER" />        </intent-filter>      </activity>      </application>  </manifest>
