Question

我想使用nexusDialog Library（https://github.com/dkharrat/NexusDialog）通过片段创建自定义元素我使用开发人员给出的示例创建了一个自定义元素但我不知道如何在片段中生成那些自定义组件而不是活动。我想将数据传递到编辑文本，并使用库

获取edittext的值

这是我的代码

自定义组件

public class EditTextComp extends FormElementController {

    EditText editText = null;

    TextView textView = null;

    public EditTextComp(Context context) {
        super(context, null);

    }


    @Override
    protected View createView() {
        return createComponent();
    }

    @Override
    public void refresh() {

    }

    @Override
    public void setError(String message) {

    }




    private View createComponent() {

        LayoutInflater inflater = LayoutInflater.from(getContext());
        return inflater.inflate(R.layout.compound_comp_edit_text, null);

    }

    public EditText getEditText() {
        return (EditText) getView().findViewById(R.id.editText);
    }

}

我能够使用图书馆FormFragment以这种方式做到这一点

儿童片段

public  class fragmentFragment extends FormFragment {
    public static final String FIRST_NAME = "firstName";
    public static final String LAST_NAME = "lastName";
    public static final String GENDER = "gender";
    public static final String HOBBIES = "hobbies";

    public boolean validate() {
        getFormController().resetValidationErrors();
        if (getFormController().isValidInput()) {
            Object firstName = getModel().getValue(FIRST_NAME);
            Object lastName = getModel().getValue(LAST_NAME);
            Object gender = getModel().getValue(GENDER);
            Object favColor = getModel().getValue(HOBBIES);

            String msg = "First name: " + firstName + "\n"
                    + "Last name: " + lastName + "\n"
                    + "Gender: " + gender + "\n"
                    + "Hobbies: " + favColor + "\n";
            MessageUtil.showAlertMessage("Field Values", msg, getActivity());
        } else {
            getFormController().showValidationErrors();
        }
        return true;
    }


    @Override
    public void initForm(FormController controller) {
        Context ctxt = getContext();
        FormSectionController section = new FormSectionController(ctxt, "Personal Info");
        section.addElement(new EditTextController(ctxt, FIRST_NAME, "First name"));
        section.addElement(new EditTextController(ctxt, LAST_NAME, "Last name"));


        controller.addSection(section);
    }
}

父级片段

  btn= view.findViewById(R.id.btn_in_xml);
        btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                FragmentManager fm = getFragmentManager() ;
                fragmentFragment formFragment;

                Fragment retainedFragment = fm.findFragmentByTag(FORM_FRAGMENT_KEY);
                if (retainedFragment != null && retainedFragment instanceof childFragment) {
                    formFragment = (childFragment) retainedFragment;
                } else {
                    formFragment = new childFragment();
                    fm.beginTransaction()
                            .replace(R.id.flContent, formFragment, FORM_FRAGMENT_KEY)
                            .commit();
                }


            }
        });
