注意：android2.3版本不支持下面的自动接听方法。(会抛异常：java.lang.SecurityException:

Neither user xxxxx nor current process has

android.permission.MODIFY_PHONE_STATE.)

第一步：准备应用环境需要的系统包和aidl文件。

(1)在应用中创建包:android.telephony

将android系统框架下的\framework\telephony\java\android\telephony目录中的NeighboringCellInfo.aidl文件复制到上面创建的包(android.telephony

)中；

(2)在应用中创建包:com.android.internal.telephony

将android系统框架下的\framework\telephony\java\com\android\internal\telephony目录中的ITelephony.aidl文件复制到上面创建的包(com.android.internal.telephony

)中；

第二步：创建一个获取ITelephony的方法

PhoneUtils.java

Java代码  

packagecom.zhouzijing.android.demo;

importjava.lang.reflect.Method;

importcom.android.internal.telephony.ITelephony;

importandroid.telephony.TelephonyManager;

publicclassPhoneUtils {

publicstaticITelephony getITelephony(TelephonyManager telephony)throwsException {

Method getITelephonyMethod = telephony.getClass().getDeclaredMethod("getITelephony");

getITelephonyMethod.setAccessible(true);//私有化函数也能使用

return(ITelephony)getITelephonyMethod.invoke(telephony);

}

}

package com.zhouzijing.android.demo;

import java.lang.reflect.Method;

import com.android.internal.telephony.ITelephony;

import android.telephony.TelephonyManager;

public class PhoneUtils {

public static ITelephony getITelephony(TelephonyManager telephony) throws Exception {

Method getITelephonyMethod = telephony.getClass().getDeclaredMethod("getITelephony");

getITelephonyMethod.setAccessible(true);//私有化函数也能使用

return (ITelephony)getITelephonyMethod.invoke(telephony);

}

}

第三步：创建电话广播拦截器

MyPhoneBroadcastReceiver.java

Java代码  

packagecom.zhouzijing.android.demo;

importcom.android.internal.telephony.ITelephony;

importandroid.content.BroadcastReceiver;

importandroid.content.Context;

importandroid.content.Intent;

importandroid.telephony.TelephonyManager;

importandroid.util.Log;

publicclassMyPhoneBroadcastReceiverextendsBroadcastReceiver {

privatefinalstaticString TAG = MyPhone.TAG;

@Override

publicvoidonReceive(Context context, Intent intent) {

String action = intent.getAction();

Log.i(TAG,"[Broadcast]"+action);

//呼入电话

if(action.equals(MyPhone.B_PHONE_STATE)){

Log.i(TAG,"[Broadcast]PHONE_STATE");

doReceivePhone(context,intent);

}

}

publicvoiddoReceivePhone(Context context, Intent intent) {

String phoneNumber = intent.getStringExtra(

TelephonyManager.EXTRA_INCOMING_NUMBER);

TelephonyManager telephony = (TelephonyManager)context.getSystemService(

Context.TELEPHONY_SERVICE);

intstate = telephony.getCallState();

switch(state){

caseTelephonyManager.CALL_STATE_RINGING:

Log.i(TAG,"[Broadcast]等待接电话="+phoneNumber);

try{

ITelephony iTelephony = PhoneUtils.getITelephony(telephony);

iTelephony.answerRingingCall();//自动接通电话

//iTelephony.endCall();//自动挂断电话

}catch(Exception e) {

Log.e(TAG,"[Broadcast]Exception="+e.getMessage(), e);

}

break;

caseTelephonyManager.CALL_STATE_IDLE:

Log.i(TAG,"[Broadcast]电话挂断="+phoneNumber);

break;

caseTelephonyManager.CALL_STATE_OFFHOOK:

Log.i(TAG,"[Broadcast]通话中="+phoneNumber);

break;

}

}

}

package com.zhouzijing.android.demo;

import com.android.internal.telephony.ITelephony;

import android.content.BroadcastReceiver;

import android.content.Context;

import android.content.Intent;

import android.telephony.TelephonyManager;

import android.util.Log;

public class MyPhoneBroadcastReceiverextends BroadcastReceiver {

private final static String TAG = MyPhone.TAG;

@Override

public void onReceive(Context context, Intent intent) {

String action = intent.getAction();

Log.i(TAG, "[Broadcast]"+action);

//呼入电话

if(action.equals(MyPhone.B_PHONE_STATE)){

Log.i(TAG, "[Broadcast]PHONE_STATE");

doReceivePhone(context,intent);

}

}

public void doReceivePhone(Context context, Intent intent) {

String phoneNumber = intent.getStringExtra(

TelephonyManager.EXTRA_INCOMING_NUMBER);

TelephonyManager telephony = (TelephonyManager)context.getSystemService(

Context.TELEPHONY_SERVICE);

int state = telephony.getCallState();

switch(state){

case TelephonyManager.CALL_STATE_RINGING:

Log.i(TAG, "[Broadcast]等待接电话="+phoneNumber);

try {

ITelephony iTelephony = PhoneUtils.getITelephony(telephony);

iTelephony.answerRingingCall();//自动接通电话

//iTelephony.endCall();//自动挂断电话

} catch (Exception e) {

Log.e(TAG, "[Broadcast]Exception="+e.getMessage(), e);

}

break;

case TelephonyManager.CALL_STATE_IDLE:

Log.i(TAG, "[Broadcast]电话挂断="+phoneNumber);

break;

case TelephonyManager.CALL_STATE_OFFHOOK:

Log.i(TAG, "[Broadcast]通话中="+phoneNumber);

break;

}

}

}

第四部：注册电话广播拦截器

MyPhone.java

Java代码  

packagecom.zhouzijing.android.demo;

importandroid.app.Activity;

importandroid.content.IntentFilter;

importandroid.os.Bundle;

importandroid.telephony.TelephonyManager;

importandroid.util.Log;

importandroid.view.View;

publicclassMyPhoneextendsActivity {

publicfinalstaticString TAG ="MyPhone";

publicfinalstaticString B_PHONE_STATE = TelephonyManager.ACTION_PHONE_STATE_CHANGED;

privateMyPhoneBroadcastReceivermBroadcastReceiver;

@Override

publicvoidonCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.my_phone);

}

//按钮1-注册广播

publicvoidregisterThis(View v) {

Log.i(TAG,"registerThis");

mBroadcastReceiver =newMyPhoneBroadcastReceiver();

IntentFilter intentFilter =newIntentFilter();

intentFilter.addAction(B_PHONE_STATE);

intentFilter.setPriority(Integer.MAX_VALUE);

registerReceiver(mBroadcastReceiver, intentFilter);

}

//按钮2-撤销广播

publicvoidunregisterThis(View v) {

Log.i(TAG,"unregisterThis");

unregisterReceiver(mBroadcastReceiver);

}

}

package com.zhouzijing.android.demo;

import android.app.Activity;

import android.content.IntentFilter;

import android.os.Bundle;

import android.telephony.TelephonyManager;

import android.util.Log;

import android.view.View;

public class MyPhone extends Activity {

public final static String TAG = "MyPhone";

public final static String B_PHONE_STATE = TelephonyManager.ACTION_PHONE_STATE_CHANGED;

private MyPhoneBroadcastReceivermBroadcastReceiver;

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.my_phone);

}

//按钮1-注册广播

public void registerThis(View v) {

Log.i(TAG, "registerThis");

mBroadcastReceiver = new MyPhoneBroadcastReceiver();

IntentFilter intentFilter = new IntentFilter();

intentFilter.addAction(B_PHONE_STATE);

intentFilter.setPriority(Integer.MAX_VALUE);

registerReceiver(mBroadcastReceiver, intentFilter);

}

//按钮2-撤销广播

public void unregisterThis(View v) {

Log.i(TAG, "unregisterThis");

unregisterReceiver(mBroadcastReceiver);

}

}

第5步：在AndroidManifest.xml配置权限

Xml代码  

其中：

Java代码  

iTelephony.answerRingingCall();//自动接通电话

iTelephony.answerRingingCall();//自动接通电话

必须有权限

android.permission.MODIFY_PHONE_STATE

Java代码  

iTelephony.endCall();//自动挂断电话

iTelephony.endCall();//自动挂断电话

必须有权限 android.permission.CALL_PHONE
