android 来电自动接听和自动挂断

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

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
