本文实例为大家分享了android实现接通和挂断电话的具体代码，供大家参考，具体内容如下

关键代码：【PhoneUtils类】

package com.ebupt.phonerecorddemo.server;

import java.lang.reflect.Method;

import android.content.Context;

import android.content.Intent;

import android.telephony.TelephonyManager;

import android.util.Log;

import android.view.KeyEvent;

import com.android.internal.telephony.ITelephony;

public class PhoneUtils {

static String TAG = "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);

}

//自动接听

public static void autoAnswerPhone(Context c,TelephonyManager tm) {

try {

Log.i(TAG, "autoAnswerPhone");

ITelephony itelephony = getITelephony(tm);

// itelephony.silenceRinger();

itelephony.answerRingingCall();

} catch (Exception e) {

e.printStackTrace();

try {

Log.e(TAG, "用于Android2.3及2.3以上的版本上");

Intent intent = new Intent("android.intent.action.MEDIA_BUTTON");

KeyEvent keyEvent = new KeyEvent(KeyEvent.ACTION_DOWN,

KeyEvent.KEYCODE_HEADSETHOOK);

intent.putExtra("android.intent.extra.KEY_EVENT", keyEvent);

c.sendOrderedBroadcast(intent,

"android.permission.CALL_PRIVILEGED");

intent = new Intent("android.intent.action.MEDIA_BUTTON");

keyEvent = new KeyEvent(KeyEvent.ACTION_UP,

KeyEvent.KEYCODE_HEADSETHOOK);

intent.putExtra("android.intent.extra.KEY_EVENT", keyEvent);

c.sendOrderedBroadcast(intent,

"android.permission.CALL_PRIVILEGED");

Intent localIntent1 = new Intent(Intent.ACTION_HEADSET_PLUG);

localIntent1.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);

localIntent1.putExtra("state", 1);

localIntent1.putExtra("microphone", 1);

localIntent1.putExtra("name", "Headset");

c.sendOrderedBroadcast(localIntent1,

"android.permission.CALL_PRIVILEGED");

Intent localIntent2 = new Intent(Intent.ACTION_MEDIA_BUTTON);

KeyEvent localKeyEvent1 = new KeyEvent(KeyEvent.ACTION_DOWN,

KeyEvent.KEYCODE_HEADSETHOOK);

localIntent2.putExtra("android.intent.extra.KEY_EVENT",

localKeyEvent1);

c.sendOrderedBroadcast(localIntent2,

"android.permission.CALL_PRIVILEGED");

Intent localIntent3 = new Intent(Intent.ACTION_MEDIA_BUTTON);

KeyEvent localKeyEvent2 = new KeyEvent(KeyEvent.ACTION_UP,

KeyEvent.KEYCODE_HEADSETHOOK);

localIntent3.putExtra("android.intent.extra.KEY_EVENT",

localKeyEvent2);

c.sendOrderedBroadcast(localIntent3,

"android.permission.CALL_PRIVILEGED");

Intent localIntent4 = new Intent(Intent.ACTION_HEADSET_PLUG);

localIntent4.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);

localIntent4.putExtra("state", 0);

localIntent4.putExtra("microphone", 1);

localIntent4.putExtra("name", "Headset");

c.sendOrderedBroadcast(localIntent4,

"android.permission.CALL_PRIVILEGED");

} catch (Exception e2) {

e2.printStackTrace();

Intent meidaButtonIntent = new Intent(

Intent.ACTION_MEDIA_BUTTON);

KeyEvent keyEvent = new KeyEvent(KeyEvent.ACTION_UP,

KeyEvent.KEYCODE_HEADSETHOOK);

meidaButtonIntent.putExtra(Intent.EXTRA_KEY_EVENT, keyEvent);

c.sendOrderedBroadcast(meidaButtonIntent, null);

}

}

}

//自动挂断

public static void endPhone(Context c,TelephonyManager tm) {

try {

Log.i(TAG, "endPhone");

ITelephony iTelephony;

Method getITelephonyMethod = TelephonyManager.class

.getDeclaredMethod("getITelephony", (Class[]) null);

getITelephonyMethod.setAccessible(true);

iTelephony = (ITelephony) getITelephonyMethod.invoke(tm,

(Object[]) null);

// 挂断电话

iTelephony.endCall();

} catch (Exception e) {

e.printStackTrace();

}

}

}

需要用到的ITelephony.aidl：

package com.android.internal.telephony;

/**

* Interface used to interact with the phone. Mostly this is used by the

* TelephonyManager class. A few places are still using this directly.

* Please clean them up if possible and use TelephonyManager instead.

* {@hide}

*/

interface ITelephony {

/**

* End call or go to the Home screen

* @return whether it hung up

*/

boolean endCall();

/**

* Answer the currently-ringing call.

*

* If there's already a current active call, that call will be

* automatically put on hold. If both lines are currently in use, the

* current active call will be ended.

*

* TODO: provide a flag to let the caller specify what policy to use

* if both lines are in use. (The current behavior is hardwired to

* "answer incoming, end ongoing", which is how the CALL button

* is specced to behave.)

*

* TODO: this should be a oneway call (especially since it's called

* directly from the key queue thread).

*/

void answerRingingCall();

/**

* Silence the ringer if an incoming call is currently ringing.

* (If vibrating, stop the vibrator also.)

*

* It's safe to call this if the ringer has already been silenced, or

* even if there's no incoming call. (If so, this method will do nothing.)

*

* TODO: this should be a oneway call too (see above).

* (Actually *all* the methods here that return void can

* probably be oneway.)

*/

void silenceRinger();

/**

* Allow mobile data connections.

*/

boolean enableDataConnectivity();

/**

* Disallow mobile data connections.

*/

boolean disableDataConnectivity();

/**

* Report whether data connectivity is possible.

*/

boolean isDataConnectivityPossible();

}

监听通话广播【PhoneReceiver.java】：

package com.ebupt.phonerecorddemo.server;

import android.app.Service;

import android.content.BroadcastReceiver;

import android.content.Context;

import android.content.Intent;

import android.telephony.TelephonyManager;

import android.util.Log;

public class PhoneReceiver extends BroadcastReceiver {

String TAG = "PhoneReceiver";

@Override

public void onReceive(Context context, Intent intent) {

TelephonyManager tm = (TelephonyManager) context

.getSystemService(Service.TELEPHONY_SERVICE);

switch (tm.getCallState()) {

case TelephonyManager.CALL_STATE_OFFHOOK:// 电话打进来接通状态；电话打出时首先监听到的状态。

Log.i("onCallStateChanged", "CALL_STATE_OFFHOOK");

break;

case TelephonyManager.CALL_STATE_RINGING:// 电话打进来状态

Log.i("onCallStateChanged", "CALL_STATE_RINGING");

PhoneUtils.autoAnswerPhone(context,tm);

break;

case TelephonyManager.CALL_STATE_IDLE:// 不管是电话打出去还是电话打进来都会监听到的状态。

Log.i("onCallStateChanged", "CALL_STATE_IDLE");

break;

}

}

}

在上面类适当的地方加上挂断或接通电话的代码即可。

最后别忘记在AndroidManifest.xml里声明和注册权限。
