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
