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

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

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

iTelephony.endCall();//自动挂断电话

 必须有权限 android.permission.CALL_PHONE
