Spinner未在Android片段

Question

我正在编写一个代码，其中spinner由来自webservice的数据填充。我正在使用改造

RestAdapter adapter = new RestAdapter.Builder().setEndpoint(InterfaceApi.URL).build();
        InterfaceApi interfaceApi = adapter.create(InterfaceApi.class);

        interfaceApi.getAdminLeaveTypes(new Callback<ArrayList<AdminLeaveTypeBeans>>() {
            @Override
            public void success(ArrayList<AdminLeaveTypeBeans> adminLeaveTypeBeanses, Response response) {
                if (adminLeaveTypeBeanses.isEmpty()) {
                    Toast.makeText(getActivity(), "No record found", Toast.LENGTH_SHORT).show();
                } else {
                    for (int i = 0; i < adminLeaveTypeBeanses.size(); i++) {
                        leaveTypeId.add(i, adminLeaveTypeBeanses.get(i).getTypeId());
                        leaveTypeName.add(i, adminLeaveTypeBeanses.get(i).getTypeName());
                    }
                }
            }

            @Override
            public void failure(RetrofitError error) {
                Toast.makeText(getActivity(), "Error..may be webservice not running", Toast.LENGTH_SHORT).show();
                Log.e("failure: ", "messgae" +error.getMessage());
            }
        });

        ArrayAdapter<String> adapterLeaveType = new ArrayAdapter<>(this.getContext(), android.R.layout.simple_list_item_1, leaveTypeName);
        spinnerLeaveAdminType.setAdapter(adapterLeaveType);

我希望在选择spinner之后设置值。任何帮助将不胜感激。感谢

Answer 1

只需在setAdapter(..)之前添加此行： -

spinnerLeaveAdminType.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

Answer 2

将项目添加到列表

后，您需要通知适配器数据更改

adapterLeaveType.notifyDataSetChanged();

Answer 3

    ArrayAdapter<String> adapterLeaveType = new ArrayAdapter<>(this.getContext(), android.R.layout.simple_list_item_1, leaveTypeName);
    spinnerLeaveAdminType.setAdapter(adapterLeaveType);

将其更改为：

    ArrayAdapter<String> adapterLeaveType = new ArrayAdapter<>(getContext(), android.R.layout.simple_list_item_1, leaveTypeName);
    adapterLeaveType.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    spinnerLeaveAdminType.setAdapter(adapterLeaveType);
