Question

如果没有要显示的文本，我想在以下代码中禁用和隐藏这些edittext实例。我已经尝试过一些东西，比如Visabilty.Gone和focusable：XML中的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);
            holeNum[3]=(EditText) view.findViewById(R.id.scorecardHoleNum4);
            holeNum[4]=(EditText) view.findViewById(R.id.scorecardHoleNum5);
            holeNum[5]=(EditText) view.findViewById(R.id.scorecardHoleNum6);

Answer 1

我认为您要检查某些条件，并在相应检查后要更改编辑文本可见性现在-xml部分也通过编程完成对于Visiblity使用 - setVisibility(View.)

启用/使用diable - setEnabled(true/false)

现在你看起来关注你的观点setFocusable(true/false)

但我建议您在检查之前添加一个默认状态..i.e 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);
        }

我跳它可以帮助你

Answer 2

To Disable the edittext,you can try the following methods:

    editText.setFocusable(false);
    editText.setEnabled(false);
    editText.setCursorVisible(false);
    editText.setKeyListener(null);
    editText.setBackgroundColor(Color.TRANSPARENT); 


In xml:

android:editable="false"

Answer 3

使用Jayman的建议，这是通过为每个数组项设置一个初始状态来实现的：

holeNum[0]=(TextView) view.findViewById(R.id.scorecardHoleNum1);
                holeNum[0].setVisibility(View.GONE);

然后是以下条件陈述：

if(holeNum[i].getText() == null){
                    holeNum[i].setVisibility(View.GONE);
                    holeNum[i].setEnabled(false);
                    holeNum[i].setFocusable(false);
                }else{
                    holeNum[i].setVisibility(View.VISIBLE);
                    holeNum[i].setEnabled(true);
                    holeNum[i].setFocusable(true);
                    holeNum[i].setText(numHole);
                }

如果为空，则禁用EditText数组索引
