java - 为什么时间选择器打不开？

Question

我正在尝试检查所选时间是否在 11:30 - 14:30 之间或 17:00 - 22:30 之间。如果是，则检查时间是否早于当前时间 +20 分钟(或交货 +45 分钟)。

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

                    EventBus.getDefault().postSticky(new EnableButtonNext(true));

                    final Calendar c = Calendar.getInstance();
                    int mHour = c.get(Calendar.HOUR_OF_DAY);
                    int mMin = c.get(Calendar.MINUTE);
                    final int currentHour = c.get(Calendar.HOUR_OF_DAY);
                    final int currentMinute = c.get(Calendar.MINUTE);
                    final int date = c.get(Calendar.DAY_OF_MONTH);
                    final int month = c.get(Calendar.MONTH);
                    final int year = c.get(Calendar.YEAR);

                                                rdi_preorder.setChecked(false);
                                                    }
                                            else {
                                                time_preorder = String.format("%2s:%2s %2s.%2s.%4s", selectedHour, selectedMin, selectedDate, selectedMonth, selectedYear);
                                                txt_time.setVisibility(View.VISIBLE);
                                                txt_time.setText(new StringBuilder("fur ").append(time_preorder).toString());
                                            }
                                        else
                                            Toast.makeText(getContext(), "Please order in our open times!", Toast.LENGTH_SHORT).show();
                                            rdi_preorder.setChecked(false);} } }

                            }, mHour, mMin, true);

                    timePickerDialog.setOnCancelListener(new DialogInterface.OnCancelListener() {
                        @Override
                        public void onCancel(DialogInterface dialogInterface) {

                        }}); } }}

我想测试我的代码，但如果我单击 rdi_preorder，则日期和时间选择器不会打开。请帮忙

调用timePickerDialog.show()来告诉对话框出现在屏幕上
