Android自动接听和挂断电话实现原理：http://blog.csdn.net/chenda_lin/article/details/41346493

Android提供的系统服务之--TelephonyManager(电话管理器)：http://www.2cto.com/kf/201410/347844.html

android 实现来电自动接听和自动挂断的方法：
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
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
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
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
<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：
iTelephony.answerRingingCall();//自动接通电话
必须有权限 android.permission.MODIFY_PHONE_STATE
iTelephony.endCall();//自动挂断电话
必须有权限 android.permission.CALL_PHONE。

添加权限
<uses-permission android:name="android.permission.CALL_PHONE"/>
<uses-permission android:name="android.permission.MODIFY_PHONE_STATE"/>

main.xml
<?xml version="1.0" encoding="utf-8"?>  
<LinearLayout xmlns:android="http：//schemas。android。com/apk/res/android"  
    androidrientation="vertical" android:layout_width="fill_parent"  
    android:layout_height="fill_parent">  
    <RadioGroup android:layout_height="wrap_content"  
        android:layout_width="fill_parent" android:id="@+id/rGrpSelect">  
        <RadioButton android:layout_height="wrap_content"  
            android:layout_width="fill_parent" android:id="@+id/rbtnAutoAccept"  
            android:text="所有来电自动接听"></RadioButton>  
        <RadioButton android:layout_height="wrap_content"  
            android:layout_width="fill_parent" android:id="@+id/rbtnAutoReject"  
            android:text="所有来电自动挂断"></RadioButton>  
    </RadioGroup>  
    <ToggleButton android:layout_height="wrap_content"  
        android:layout_width="fill_parent" android:id="@+id/tbtnRadioSwitch"  
        android:textOn="Radio已经启动" android:textOff="Radio已经关闭"  
        android:textSize="24dip" android:textStyle="normal"></ToggleButton>  
    <ToggleButton android:layout_height="wrap_content"  
        android:layout_width="fill_parent" android:id="@+id/tbtnDataConn"  
        android:textSize="24dip" android:textStyle="normal" android:textOn="允许数据连接"  
        android:textOff="禁止数据连接"></ToggleButton>  
</LinearLayout>  

PhoneUtils.java是手机功能类，从TelephonyManager中实例化ITelephony并返回，源码如下：
package com.testTelephony;  
  
import java.lang.reflect.Field;  
import java.lang.reflect.Method;  
import com.android.internal.telephony.ITelephony;  
import android.telephony.TelephonyManager;  
import android.util.Log;  
  
public class PhoneUtils {  
    /** 
     * 从TelephonyManager中实例化ITelephony，并返回 
     */  
    static public ITelephony getITelephony(TelephonyManager telMgr) throws Exception {  
        Method getITelephonyMethod = telMgr.getClass().getDeclaredMethod("getITelephony");  
        getITelephonyMethod.setAccessible(true);//私有化函数也能使用  
        return (ITelephony)getITelephonyMethod.invoke(telMgr);  
    }  
      
    static public void printAllInform(Class clsShow) {    
        try {    
            // 取得所有方法    
            Method[] hideMethod = clsShow.getDeclaredMethods();    
            int i = 0;    
            for (; i < hideMethod.length; i++) {    
                Log.e("method name", hideMethod.getName());    
            }    
            // 取得所有常量    
            Field[] allFields = clsShow.getFields();    
            for (i = 0; i < allFields.length; i++) {    
                Log.e("Field name", allFields.getName());    
            }    
        } catch (SecurityException e) {    
            // throw new RuntimeException(e.getMessage());    
            e.printStackTrace();    
        } catch (IllegalArgumentException e) {    
            // throw new RuntimeException(e.getMessage());    
            e.printStackTrace();    
        } catch (Exception e) {    
            // TODO Auto-generated catch block    
            e.printStackTrace();    
        }    
    }    
}  
testTelephony.java是主类，使用PhoneStateListener监听通话状态，以及实现上述4种电话控制功能，源码如下：
package com.testTelephony;  
  
import android.app.Activity;  
import android.os.Bundle;  
import android.telephony.PhoneStateListener;  
import android.telephony.TelephonyManager;

import android.widget.ToggleButton;  
  
public class testTelephony extends Activity {  
    /** Called when the activity is first created. */  
    RadioGroup rg;//来电操作单选框  
    ToggleButton tbtnRadioSwitch;//Radio开关  
    ToggleButton tbtnDataConn;//数据连接的开关  
    TelephonyManager telMgr;  
    CallStateListener stateListner;  
    int checkedId=0;  
    @Override  
    public void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);  
        setContentView(R.layout.main);  
          
        telMgr= (TelephonyManager)getSystemService(TELEPHONY_SERVICE);  
        telMgr.listen(new CallStateListener(), CallStateListener.LISTEN_CALL_STATE);  
          
        PhoneUtils.printAllInform(TelephonyManager.class);  
          
        rg = (RadioGroup)findViewById(R.id.rGrpSelect);  
        rg.setOnCheckedChangeListener(new CheckEvent());  
        tbtnRadioSwitch=(ToggleButton)this.findViewById(R.id.tbtnRadioSwitch);  
        tbtnRadioSwitch.setOnClickListener(new ClickEvent());  
        try {  
            tbtnRadioSwitch.setChecked(PhoneUtils.getITelephony(telMgr).isRadioOn());  
        }  catch (Exception e) {  
            Log.e("error",e.getMessage());  
        }  
        tbtnDataConn=(ToggleButton)this.findViewById(R.id.tbtnDataConn);  
        tbtnDataConn.setOnClickListener(new ClickEvent());  
        try {  
            tbtnDataConn.setChecked(PhoneUtils.getITelephony(telMgr).isDataConnectivityPossible());  
        }  catch (Exception e) {  
            Log.e("error",e.getMessage());  
        }  
    }

            testTelephony.this.checkedId=checkedId;  
        }  
    }  
      
    /**

                } catch (Exception e) {  
                    Log.e("error", e.getMessage());  
                }  
            }

                        PhoneUtils.getITelephony(telMgr).enableDataConnectivity();  
                    else if(!tbtnDataConn.isChecked())  
                        PhoneUtils.getITelephony(telMgr).disableDataConnectivity();
