android自动接听电话

㈠ android怎么实现自动接听和挂断电话功能

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。

㈡ Android手机在链接蓝牙后，可以这样设置吗：来电 手机响铃声，然后选择蓝牙接听，也可以选择手机接听

可以，操作方法如下：

1、首先点击手机桌面中的设置，如下图所示。
