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】

packagecom.ebupt.phonerecorddemo.server;

importjava.lang.reflect.Method;
importandroid.content.Context;
importandroid.content.Intent;
importandroid.telephony.TelephonyManager;
importandroid.util.Log;
importandroid.view.KeyEvent;

importcom.android.internal.telephony.ITelephony;

publicclassPhoneUtils{
staticStringTAG="PhoneUtils";
/**
*从TelephonyManager中实例化ITelephony,并返回
*/
staticpublicITelephonygetITelephony(TelephonyManagertelMgr)
throwsException{
MethodgetITelephonyMethod=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
publicstaticvoidautoAnswerPhone(Contextc,TelephonyManagertm){
try{
Log.i(TAG,"autoAnswerPhone");
ITelephonyitelephony=getITelephony(tm);
//itelephony.silenceRinger();
itelephony.answerRingingCall();
}catch(Exceptione){
e.printStackTrace();
try{
Log.e(TAG,"用于Android2.3及2.3以上的版本上");
Intentintent=newIntent("android.intent.action.MEDIA_BUTTON");
KeyEventkeyEvent=newKeyEvent(KeyEvent.ACTION_DOWN,
KeyEvent.KEYCODE_HEADSETHOOK);
intent.putExtra("android.intent.extra.KEY_EVENT",keyEvent);
c.sendOrderedBroadcast(intent,
"android.permission.CALL_PRIVILEGED");
intent=newIntent("android.intent.action.MEDIA_BUTTON");
keyEvent=newKeyEvent(KeyEvent.ACTION_UP,
KeyEvent.KEYCODE_HEADSETHOOK);
intent.putExtra("android.intent.extra.KEY_EVENT",keyEvent);
c.sendOrderedBroadcast(intent,
"android.permission.CALL_PRIVILEGED");
IntentlocalIntent1=newIntent(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");
IntentlocalIntent2=newIntent(Intent.ACTION_MEDIA_BUTTON);
KeyEventlocalKeyEvent1=newKeyEvent(KeyEvent.ACTION_DOWN,
KeyEvent.KEYCODE_HEADSETHOOK);
localIntent2.putExtra("android.intent.extra.KEY_EVENT",
localKeyEvent1);
c.sendOrderedBroadcast(localIntent2,
"android.permission.CALL_PRIVILEGED");
IntentlocalIntent3=newIntent(Intent.ACTION_MEDIA_BUTTON);
KeyEventlocalKeyEvent2=newKeyEvent(KeyEvent.ACTION_UP,
KeyEvent.KEYCODE_HEADSETHOOK);
localIntent3.putExtra("android.intent.extra.KEY_EVENT",
localKeyEvent2);
c.sendOrderedBroadcast(localIntent3,
"android.permission.CALL_PRIVILEGED");
IntentlocalIntent4=newIntent(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(Exceptione2){
e2.printStackTrace();
IntentmeidaButtonIntent=newIntent(
Intent.ACTION_MEDIA_BUTTON);
KeyEventkeyEvent=newKeyEvent(KeyEvent.ACTION_UP,
KeyEvent.KEYCODE_HEADSETHOOK);
meidaButtonIntent.putExtra(Intent.EXTRA_KEY_EVENT,keyEvent);
c.sendOrderedBroadcast(meidaButtonIntent,null);
}
}
}

//自动挂断
publicstaticvoidendPhone(Contextc,TelephonyManagertm){
try{
Log.i(TAG,"endPhone");
ITelephonyiTelephony;
MethodgetITelephonyMethod=TelephonyManager.class
.getDeclaredMethod("getITelephony",(Class[])null);
getITelephonyMethod.setAccessible(true);
iTelephony=(ITelephony)getITelephonyMethod.invoke(tm,
(Object[])null);
//挂断电话
iTelephony.endCall();
}catch(Exceptione){
e.printStackTrace();
}
}

}

需要用到的ITelephony.aidl：

packagecom.android.internal.telephony;
/**
*Interfaceusedtointeractwiththephone.Mostlythisisusedbythe
*TelephonyManagerclass.Afewplacesarestillusingthisdirectly.
*PleasecleanthemupifpossibleanduseTelephonyManagerinstead.
*{@hide}
*/

interfaceITelephony{
/**
*EndcallorgototheHomescreen
*@returnwhetherithungup
*/
booleanendCall();

/**
*Answerthecurrently-ringingcall.
*
*Ifthere'salreadyacurrentactivecall,thatcallwillbe
*automaticallyputonhold.Ifbothlinesarecurrentlyinuse,the
*currentactivecallwillbeended.
*
*TODO:provideaflagtoletthecallerspecifywhatpolicytouse

*"answerincoming,endongoing",whichishowtheCALLbutton

*
*TODO:thisshouldbeaonewaycall(especiallysinceit'scalled

*/
voidanswerRingingCall();

/**
*Silencetheringerifanincomingcalliscurrentlyringing.
*(Ifvibrating,stopthevibratoralso.)
*
*It'ssafetocallthisiftheringerhasalreadybeensilenced,or
*evenifthere'snoincomingcall.(Ifso,thismethodwilldonothing.)

*/
voidsilenceRinger();

/**
*Allowmobiledataconnections.
*/
booleanenableDataConnectivity();

/**
*Disallowmobiledataconnections.
*/
booleandisableDataConnectivity();

/**
*Reportwhetherdataconnectivityispossible.
*/
booleanisDataConnectivityPossible();
}

监听通话广播【PhoneReceiver.java】：

packagecom.ebupt.phonerecorddemo.server;

importandroid.app.Service;
importandroid.content.BroadcastReceiver;
importandroid.content.Context;
importandroid.content.Intent;
importandroid.telephony.TelephonyManager;
importandroid.util.Log;

publicclassPhoneReceiverextendsBroadcastReceiver{
StringTAG="PhoneReceiver";
@Override
publicvoidonReceive(Contextcontext,Intentintent){
TelephonyManagertm=(TelephonyManager)context
.getSystemService(Service.TELEPHONY_SERVICE);
switch(tm.getCallState()){
caseTelephonyManager.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;
caseTelephonyManager.CALL_STATE_RINGING://电话打进来状态
Log.i("onCallStateChanged","CALL_STATE_RINGING");
PhoneUtils.autoAnswerPhone(context,tm);
break;
caseTelephonyManager.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。
