java - 如果为空，则禁用 EditText 数组索引

Question

如果没有要显示的文本，我想在以下代码中禁用并隐藏这些 edittext 实例。我已经尝试了一些东西，例如 XML 中的 Visabilty.Gone 和 focusable:false 但没有骰子:

代码:

   private EditText scorecardCourse;
private EditText scorecardDate;

private SQLiteHandler db;

@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    db = new SQLiteHandler(getActivity().getApplicationContext());

    HashMap<String, String> rounds = db.getRoundsDetails();

    if(db.getRoundsDetails().size() != 0){

        View view = inflater.inflate(R.layout.fragment_scorecards, container, false);

        ((MainActivity) getActivity())
                .setActionBarTitle("Scorecard");

        scorecardCourse = (EditText) view.findViewById(R.id.course);
        scorecardCourse.setEnabled(false);
        scorecardDate = (EditText) view.findViewById(R.id.date);
        scorecardDate.setEnabled(false);


        final String course = rounds.get("courseName");
        final String date = rounds.get("date");

            scorecardCourse.setText(course);
            scorecardDate.setText(date);


            ArrayList<HashMap<String, String>> arrayList = new ArrayList<HashMap<String, String>>();
            arrayList = db.getAllHoles();

            if(arrayList.size() != 0){

            EditText []holeNum = new EditText[18];
            holeNum[0]=(EditText) view.findViewById(R.id.scorecardHoleNum1);
            holeNum[1]=(EditText) view.findViewById(R.id.scorecardHoleNum2);
            holeNum[2]=(EditText) view.findViewById(R.id.scorecardHoleNum3);

我认为您想要检查某些条件，并且在相应检查后您想要更改编辑文本可见性 现在-xml部分也通过编程完成 对于可见性使用 -setVisibility(View.)

对于启用/禁用使用-setEnabled(true/false)

现在你所看到的焦点集中在你的 View 上setFocusable(true/false)

但我建议您在检查之前添加一个默认状态..即 yourtextview.visibility(View.Gone);

完整代码

if(your condition)
        {
            yourtextview.setVisibility(View.GONE);
            yourtextview.setEnabled(false);
            yourtextview.setFocusable(false);
        }

        else
        {
            yourtextview.setVisibility(View.VISIBLE);
            yourtextview.setEnabled(true);
            yourtextview.setFocusable(true);
        }

希望对你有帮助
