android 来电自动接听和自动挂断

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??

package?com.zhouzijing.android.demo;??
??
import?java.lang.reflect.Method;??
import?com.android.internal.telephony.ITelephony;??
import?android.telephony.TelephonyManager;??
??
public?class?PhoneUtils?{??
????/**?
?????*?根据传入的TelephonyManager来取得系统的ITelephony实例.?
?????*?@param?telephony?
?????*?@return?系统的ITelephony实例?
?????*?@throws?Exception?
?????*/??
????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??

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?MyPhoneBroadcastReceiver?extends?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);??
????????}??
????}??
??????
????/**?
?????*?处理电话广播.?
?????*?@param?context?
?????*?@param?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??

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?MyPhoneBroadcastReceiver?mBroadcastReceiver;??
??????
????@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??

<uses-permission?android:name="android.permission.READ_PHONE_STATE"?/>??
<uses-permission?android:name="android.permission.MODIFY_PHONE_STATE"?/>??
<uses-permission?android:name="android.permission.CALL_PHONE"/>??

其中：

Java代码??

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??

?必须有权限 android.permission.CALL_PHONE
