  1. 我正在做一个小型 Android 应用程序。
  2. 因为我有一个带有物品清单的微调器（前品牌，颜色）。
  3. 而且我还有 MultiAutoCompleteTextView。
  4. 我创建了两个自定义阵列适配器颜色适配器和品牌适配器。
  5. 颜色适配器保存与颜色相关的值，品牌适配器保存与品牌相关的值。
  6. 在这里，我要做的是验证微调器中的选定项目，例如如果我在微调器中选择颜色，然后在 MultiAutoCompleteTextView 中，它应该给我颜色适配器中的值。如果我选择 Brand In Spinner 然后 Values In Brand 适配器。
  7. 谁能帮我锄头做这个...
  8. 这是我的代码到目前为止我尝试过的内容。

尝试这个，

spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
            String text = spinner.getSelectedItem().toString();
            Log.d("!!!!!!!!!!!!", "onItemSelected: "+text);
            if(text.equals("Color")){
                 text1.setAdapter(clistAdapter);
            }  else if(text.equals("Brand")){
                 text1.setAdapter(blistAdapter);
            }  
        }

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

        }
