Question

让我们说vocSpinner值=＆＃34;战斗/服务＆＃34;和popSpinner值=＆＃34; NSmen＆＃34;我检查cb1。它会给出一个清单。但是，当我将popSpinner更改为＆＃34; Regular / NSF＆＃34;它将更改为另一个列表（这是正确的），但如何取消选中该复选框，而不创建其他重叠数据。我提供的代码似乎没有用，我无法解决。欢迎所有的帮助，提前谢谢！

private String[] vocSpinner;
private String[] popSpinner;

private List<Standard> standardList = new ArrayList<>();
private RecyclerView recyclerView;
private StandardsAdapter sAdapter;
private CheckBox cb1;
private CheckBox cb2;

cb1 = (CheckBox) getActivity().findViewById(R.id.pushUp);
cb2 = (CheckBox) getActivity().findViewById(R.id.sitUp);

this.vocSpinner = new String[]{
            "CDO/Diver/Gds/Fitness Spec", "Combat/Service"

this.popSpinner = new String[]{
            "NSmen", "Regular/NSF", "Pre-enlistee"

final Spinner v = (Spinner) getActivity().findViewById(R.id.spinner_Voc);

                        cb1.setChecked(false);
                        cb2.setChecked(false);

                        addStandardToList("Silver - $200", ">74pts");
                        addStandardToList("Incentive", "NA");
                        addStandardToList("Pass", ">60pts");
                        sAdapter.notifyDataSetChanged();

Answer 1

从以下代码中获取cb：

View myView = list.getChildAt(index);
CheckBox checkItem = (CheckBox) myView.findViewById(R.id.checkboxId);
checkItem.setChecked(false);

Answer 2

在您的微调器的onItemSelected侦听器中

cb1.setEnabled(true); 
cb2.setEnabled(true);

在下面你也应该

cb1.setChecked(false); 
cb2.setChecked(false);

如果未选中任何复选框，则会手动选择先前选择的微调器的相同值，以便调用微调器的选择侦听器，并根据微调器值重新填充数组。为此，请在其他地方执行以下操作 -

String getSelectedItemP = p.getSelectedItem().toString();
                    p.setSelection(((ArrayAdapter<String>)p.getAdapter()).getPosition(getSelectedItemP));
                    String getSelectedItemV = v.getSelectedItem().toString();
                    v.setSelection(((ArrayAdapter<String>)p.getAdapter()).getPosition(getSelectedItemV));

所以你的那个如果条件onCheckedChanged看起来像

 if (v.getSelectedItem().equals("CDO/Diver/Gds/Fitness Spec") || v.getSelectedItem().equals("Combat/Service") && p.getSelectedItem().equals("NSmen")) {
                if (cb1.isChecked() && cb2.isChecked()) {
                    addStandardToList("Gold - $500", "NA");
                    addStandardToList("Silver - $300", "NA");
                    addStandardToList("Incentive - $200", "NA");
                    addStandardToList("Pass", ">25pts");
                    sAdapter.notifyDataSetChanged();
                } else if (cb1.isChecked() || cb2.isChecked()) {
                    addStandardToList("Gold - $500", "NA");
                addStandardToList("Silver - $300", "NA");
                addStandardToList("Incentive - $200", "NA");
                addStandardToList("Pass", ">38pts");
                sAdapter.notifyDataSetChanged();
                }else{
                    // select spinner again here manually.
                    String getSelectedItemP = p.getSelectedItem().toString();
                    p.setSelection(((ArrayAdapter<String>)p.getAdapter()).getPosition(getSelectedItemP));
                    String getSelectedItemV = v.getSelectedItem().toString();
                    v.setSelection(((ArrayAdapter<String>)p.getAdapter()).getPosition(getSelectedItemV));
                }
            }

如何在新的微调器值上取消选中复选框？
