Question

我正在尝试隐藏或显示编辑文本，从我的应用程序中的微调器中选择项目。这是代码，请建议如何解决它

 ArrayAdapter adapter1 = ArrayAdapter.createFromResource(
            this, R.array.country_array, android.R.layout.simple_spinner_item);
        adapter1.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        spinner1.setAdapter(adapter1);
 spinner1.setOnItemSelectedListener(new OnItemSelectedListener() {
     @Override
     public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) {
         rlDate.setVisibility(View.VISIBLE);
         rlTime.setVisibility(View.VISIBLE);

     }

     @Override
     public void onNothingSelected(AdapterView<?> parentView) {

     }
 });

Answer 1

rlDate.setVisibility(View.GONE);

会使视图'消失'。

Answer 2

希望你的微调器和它的点击事件很好。然后你可以添加下面的代码来禁用或编辑edittext：

     int count = 0;
         spinner1.setOnItemSelectedListener(new OnItemSelectedListener() {
             @Override
             public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) {
            **if(count == 0){
               rlDate.setVisibility(View.VISIBLE);
              count == 1;
            }else{
              rlDate.setVisibility(View.INVISIBLE);
              count = 0;
        }**
   }
    });

每次点击spinner时都会设置edittext的可见性。希望这可行..

这就是我实现我的想法：

spinner1.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {

@Override
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {

            if (Objects.equals(spinner1.getSelectedItem().toString(), "<item_text_value>")) {

                rlDate.setVisibility(View.VISIBLE);
                rlTime.setVisibility(View.VISIBLE);

            } 
        }

        @Override
        public void onNothingSelected(AdapterView<?> parent) {

            rlDate.setVisibility(View.GONE);
            rlTime.setVisibility(View.GONE);

        }
    });

希望这有助于你 - 如果你仍然遇到这个问题 - 或者其他任何人正在使用它。

干杯！
