监听来电情况(静音)

在main.xml中：

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

<LinearLayout

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

  android:orientation="vertical"

  </LinearLayout>

</LinearLayout>

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 android.app.Service;

import android.content.Context;

import android.content.Intent;

import android.media.AudioManager;

import android.os.Binder;

       return "过滤电话“" + PhoneService.this.phoneNumber + "”设置成功！";

     }

         }

         break;

       case TelephonyManager.CALL_STATE_OFFHOOK: // 接听电话

         break;

       }

     }

  }

}

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;

import android.content.Intent;

import android.content.ServiceConnection;

import android.os.Bundle;

import android.os.IBinder;

import android.os.RemoteException;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

import android.widget.EditText;

import android.widget.Toast;

public class MyPhoneDemo extends Activity {

  private EditText phoneNumber = null ;

  private Button setNumber = null ;

  private Button cancelNumber = null ;

  private IService service = null ;

  private ServiceConnectionImpl serviceConnection = new ServiceConnectionImpl() ;

  @Override

  public void onCreate(Bundle savedInstanceState) {

     super.onCreate(savedInstanceState);

     super.setContentView(R.layout.main);

     this.phoneNumber = (EditText) super.findViewById(R.id.phonenumber) ;

     this.setNumber = (Button) super.findViewById(R.id.setnumber) ;

     this.cancelNumber = (Button) super.findViewById(R.id.cancelnumber) ;

     this.setNumber.setOnClickListener(new SetOnClickListenerImpl()) ;

     this.cancelNumber.setOnClickListener(new CancelOnClickListenerImpl()) ;

  }

  private class SetOnClickListenerImpl implements OnClickListener {

     public void onClick(View v) {

       Intent intent = new Intent(MyPhoneDemo.this,PhoneService.class) ;

       intent.putExtra("phonenumber", MyPhoneDemo.this.phoneNumber

            .getText().toString());

       MyPhoneDemo.this.bindService(intent,

            MyPhoneDemo.this.serviceConnection,

            Context.BIND_AUTO_CREATE);

     }

  }

  private class CancelOnClickListenerImpl implements OnClickListener {

     public void onClick(View v) {

       if(MyPhoneDemo.this.service != null) {

         MyPhoneDemo.this.unbindService(MyPhoneDemo.this.serviceConnection) ;

         MyPhoneDemo.this.stopService(new Intent(MyPhoneDemo.this,PhoneService.class)) ;

         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() ;

       } catch (RemoteException e) {

       }

     }

     public void onServiceDisconnected(ComponentName name) {

     }

  }

}

修改AndroidManifest.xml：

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

    package="com.li.phone"

    android:versionCode="1"

    android:versionName="1.0" >

    <uses-sdk

        android:minSdkVersion="8"

        android:targetSdkVersion="15" />

       </intent-filter>

     </receiver>

    </application>

</manifest>
