其工作code。
首先找出其呼入电话使用国家广播接收器。

Its working code. First find out that its incoming call using Phone state Broadcast Receiver.

    filter.addAction("android.intent.action.PHONE_STATE");
    mContext.registerReceiver(myCallReceiver, filter);

，然后在的onReceive（上下文的背景下，意图意图）调用answerPhoneHeadsethook（）函数。

and then in onReceive(Context context, Intent intent) call answerPhoneHeadsethook() function.

private void answerPhoneHeadsethook(Context context) {
    // Simulate a press of the headset button to pick up the call
    Intent buttonDown = new Intent(Intent.ACTION_MEDIA_BUTTON);
    buttonDown.putExtra(Intent.EXTRA_KEY_EVENT, new KeyEvent(
            KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_HEADSETHOOK));
    context.sendOrderedBroadcast(buttonDown,
            "android.permission.CALL_PRIVILEGED");

    // froyo and beyond trigger on buttonUp instead of buttonDown
    Intent buttonUp = new Intent(Intent.ACTION_MEDIA_BUTTON);
    buttonUp.putExtra(Intent.EXTRA_KEY_EVENT, new KeyEvent(
            KeyEvent.ACTION_UP, KeyEvent.KEYCODE_HEADSETHOOK));
    context.sendOrderedBroadcast(buttonUp,
            "android.permission.CALL_PRIVILEGED");
}
