使用AIDL挂断电话

AIDL是Android接口描述语言。

最早的Android中提供了自动挂断电话的功能，但是随着版本的升高这些功能已经被

隐藏起来了，所以要想完成挂断电话的功能，则要依靠AIDL技术完成。

 

在main.xml中：

 

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout

  xmlns:android="http://schemas.android.com/apk/res/android"

  android:orientation="vertical"

  android:layout_width="fill_parent"

  android:layout_height="fill_parent"

  android:gravity="center_horizontal"

  android:background="#00ff33">

  <EditText

     android:id="@+id/phonenumber"

     android:layout_margin="8dp"

     android:layout_width="fill_parent"

     android:layout_height="wrap_content"/>

  <LinearLayout

      android:layout_width="wrap_content"

      android:layout_height="wrap_content"

      android:orientation="horizontal">

     <Button

       android:id="@+id/setnumber"

       android:layout_width="100dp"

       android:layout_height="40dp"

       android:textColor="#ffffff"

       android:background="#3399ff"

       android:text="设置黑名单"/>

     <Button

       android:id="@+id/cancelnumber"

       android:layout_marginLeft="20dp"

       android:layout_width="100dp"

       android:layout_height="40dp"

       android:textColor="#ffffff"

       android:background="#3399ff"

       android:text="取消黑名单"/>

  </LinearLayout>

</LinearLayout>

 

 

 

在src下新建包：com.android.internal.telephony，（包名不能改）

并新建文件ITelephony.aidl

 

在ITelephony.aidl中：

 

package com.android.internal.telephony ;

interface ITelephony {

  boolean endCall() ;  // 挂断电话

  void answerRingingCall() ;  // 拨打电话

}

 

 

 

 

 

在IService.java中：

 

package com.li.phone;

 

public interface IService {

 

}

 

 

 

 

 

在PhoneBroadcastReceiver.java中：

 

package com.li.phone;

 

import android.content.BroadcastReceiver;

import android.content.Context;

import android.content.Intent;

 

public class PhoneBroadcastReceiver extends BroadcastReceiver {

 

  @Override

  public void onReceive(Context context, Intent intent) {

     if (Intent.ACTION_NEW_OUTGOING_CALL.equals(intent.getAction())) { // 去电

       String outgoingNumber = intent

            .getStringExtra(Intent.EXTRA_PHONE_NUMBER); // 去电号码

       Intent pit = new Intent(context, PhoneService.class);

       pit.putExtra("outgoingNumber", outgoingNumber);

       context.startService(pit);

     } else { // 来电

       context.startService(new Intent(context, PhoneService.class));

     }

  }

 

}

 

 

 

 

在PhoneService.java中：

 

package com.li.phone;

 

import java.lang.reflect.Method;

 

import android.app.Service;

import android.content.Context;

import android.content.Intent;

import android.media.AudioManager;

import android.os.Binder;

import android.os.IBinder;

import android.os.RemoteException;

import android.telephony.PhoneStateListener;

import android.telephony.TelephonyManager;

 

import com.android.internal.telephony.ITelephony;

 

public class PhoneService extends Service {

  private TelephonyManager telephony = null;

  private AudioManager audio = null; // 声音服务

  private String phoneNumber = null; // 要过滤的电话

  private IBinder myBinder = new BinderImpl();

 

  class BinderImpl extends Binder implements IService {

 

     @Override

     public String getInterfaceDescriptor() {

       return "黑名单号码" + PhoneService.this.phoneNumber + "设置成功！";

     }

 

  }

 

  @Override

  public IBinder onBind(Intent intent) {

     this.phoneNumber = intent.getStringExtra("phonenumber"); // 取得电话号码

     this.audio = (AudioManager) super

         .getSystemService(Context.AUDIO_SERVICE); // 声音服务

     this.telephony = (TelephonyManager) super

         .getSystemService(Context.TELEPHONY_SERVICE);

     this.telephony.listen(new PhoneStateListenerImpl(),

         PhoneStateListener.LISTEN_CALL_STATE); // 设置监听操作

     return this.myBinder;

  }

 

  private class PhoneStateListenerImpl extends PhoneStateListener {

 

     @Override

     public void onCallStateChanged(int state, String incomingNumber) {

       switch (state) {

       case TelephonyManager.CALL_STATE_IDLE: // 挂断电话

         PhoneService.this.audio

              .setRingerMode(AudioManager.RINGER_MODE_NORMAL); // 正常音

         break;

       case TelephonyManager.CALL_STATE_RINGING: // 领音响起

         if (incomingNumber.equals(PhoneService.this.phoneNumber)) { // 电话号码匹配

            ITelephony iTelephony = getITelephony() ;

            if (iTelephony != null) {

              try {

                iTelephony.endCall() ; // 挂断电话

              } catch (RemoteException e) {

                e.printStackTrace();

              }

            }

         }

         break;

       case TelephonyManager.CALL_STATE_OFFHOOK: // 接听电话

         break;

       }

     }

  }

 

  private ITelephony getITelephony() {

     ITelephony iTelephony = null ;

     Class<TelephonyManager> cls = TelephonyManager.class ;

     Method getITelephonyMethod = null ;

     try {

       getITelephonyMethod = cls.getDeclaredMethod("getITelephony") ;

       getITelephonyMethod.setAccessible(true) ; // 取消封装

     } catch (Exception e) {

     }

     try {

       iTelephony = (ITelephony) getITelephonyMethod

            .invoke(this.telephony);

       return iTelephony ;

     } catch (Exception e) {

     }

     return iTelephony ;

  }

}

 

 

 

 

在MyPhoneDemo.java中：

 

package com.li.phone;

 

 

import com.li.phone.PhoneService.BinderImpl;

 

import android.app.Activity;

import android.content.ComponentName;

import android.content.Context;

         Toast.makeText(MyPhoneDemo.this, "黑名单已取消", Toast.LENGTH_LONG)

              .show();

         MyPhoneDemo.this.service = null ;

       }

     }

  }

  private class ServiceConnectionImpl implements ServiceConnection {

     public void onServiceConnected(ComponentName name, IBinder service) {

       MyPhoneDemo.this.service = (BinderImpl) service ;

       try {

          Toast.makeText(MyPhoneDemo.this, service.getInterfaceDescriptor(), Toast.LENGTH_LONG).show() ;

       }

     }

 

     public void onServiceDisconnected(ComponentName name) {

      

     }
