来电接听问题

[HeroicDragon]

在安卓4.0以上的版本，使用以下方式接听来电

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);
context.sendOrderedBroadcast(meidaButtonIntent, null);


结果，发现在华为手机上无法接听。

经过试验，分别试了222个KEYCODE都无法接听电话，在这些键中，有几个是音乐播放键，这些键都能生效，唯独KEYCODE_HEADSETHOOK这个键不能接听电话。

跪求大家赐教！

try { 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); context.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); context.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"); context.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); context.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); context.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"); context.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); context.sendOrderedBroadcast(meidaButtonIntent, null); } 以上是上帖中给的方法，结果还是无法接听

可以连上电脑，用华为自带的先操作一遍，然后看看logcat，相信里面有你想要的内容

看了，没有报任何异常，我一直坚信有一个键可以启接听，害得我把222个键值全部试完，结果还是失败告终
