RadioButton自身無法檢查

Question

我正在訂購應用程序。 如果實際時間在開放時間，則應將rdi_now的可見性設置為可見，否則將其設置為已消失，因此用戶只能在封閉時間內選擇預購，但rdi_preorder沒有做應做的事情。 如果我單擊“日期選擇器”或“取消”上的時間選擇器，則rdi_preorder不會被選中。 沒錯。 這應該發生。 不應該發生的是，如果在單擊“取消”后，再次嘗試檢查rdi_preorder，它會先檢查0.2秒，然后再次取消選中，但日期和時間選擇器對話框將打開，並且我可以設置時間和設置的時間顯示在txt_time。 但是rdi_preorder仍未選中。 我在代碼中找不到問題。

private void initView(View view) {
        rdi_delivery = (RadioButton) view.findViewById(R.id.rdi_delivery);
        rdi_pickup = (RadioButton) view.findViewById(R.id.rdi_pickup);
        rdi_now = (RadioButton) view.findViewById(R.id.rdi_now);
        rdi_preorder = (RadioButton) view.findViewById(R.id.rdi_preorder);

        txt_time = (TextView) view.findViewById(R.id.txt_time);


        rdi_preorder.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
                if (b) {

Answer 1

您有一些if語句，其形式為：

...
rdi_preorder.setChecked(false);
                                            } else {
// there is no code to set preorder to true, add the following line
rdi_preorder.setChecked(true); //now when time is in the future preorder is checked

嘗試將其添加到您的if語句中
