我正在創建一個使用Sphero機器人球的遊戲。當遊戲啓動/恢復時,它會檢查配對或連接的球。如果藍牙關閉,或者沒有配對球,它將隱藏連接窗口。如果有球配對,但沒有連接,則轉到該功能。Android - Sphero - CalledFromWrongThreadException
// If the user clicked a Sphero and it failed to connect, this event will be fired
@Override
public void onRobotConnectionFailed(Robot robot) {
Log.d("activity", "onRobotConnectionFailed");
removeConnectionView();
}
它以下面的方法崩潰。
private void removeConnectionView() {
mFrameLayout.removeView(mSpheroConnectionView);
mSpheroConnectionView = null;
}
此功能對彼此可能的結果起作用。 這是錯誤。
