隐藏和取消隐藏EditText

Question

我试图隐藏或显示编辑文本选择项目从我的app.Here是代码，请建议如何修复它

 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);

将使视图“消失”。

Answer 2

希望你的微调器和它的点击事件是fine..Then的，你可以添加下面的代码来禁用或取消编辑文本：

     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;
        }**
   }
    });

它会在你每次点击spinner.Hope this works时设置edittext的可见性。

Answer 3

这就是我如何实现我认为您正在尝试的：

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);

        }
    });

希望这能帮助你，在你仍然有这个问题的情况下，-or任何其他人目前有它。

干杯!
