Question

我想设置一个可以在android 4.0版本之上自动接收调用的函数。像这样的代码：

synchronized void autoAnswerCall(){

  Context context = TApplication.nowApplication;

   try

         {

          //insert earphones

             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");

             context.sendOrderedBroadcast(localIntent1, "android.permission.CALL_PRIVILEGED");


             //Press the headset button

             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);

             context.sendOrderedBroadcast(localIntent2, "android.permission.CALL_PRIVILEGED");


             //Open the headset button

             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);

             context.sendOrderedBroadcast(localIntent3, "android.permission.CALL_PRIVILEGED");


             //Pull out earphones

             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");

             context.sendOrderedBroadcast(localIntent4, "android.permission.CALL_PRIVILEGED");

         }catch (Exception e){

             e.printStackTrace();

         }

}

它实现了模拟器和手机android2.3中的自动应答功能。它也可以在android4.0模拟器中。但在android4.0手机中却无法实现。

我使用aidl反射，它不能。如何实现Android4.0手机中的自动应答功能？有什么想法吗？

您可以使用Telephony管理器接收您的振铃电话，为此您必须将此代码放入广播接收器

 if(state.equalsIgnoreCase(TelephonyManager.EXTRA_STATE_RINGING))
        {          
            TelephonyManager telephony = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);  
            Class c = null;
                 c = Class.forName(telephony.getClass().getName());
                 Method m = null;
                 m = c.getDeclaredMethod("getITelephony");
                 m.setAccessible(true);              
                telephonyService = (ITelephony) m.invoke(telephony);
                telephonyService.answerRingingCall();

       }
