android spinner数据动态加载方法

Spinner 数据动态加载方法有以下几种方式：

1. 使用 ArrayAdapter：

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, yourDataList); adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); spinner.setAdapter(adapter); 

2. 使用 SimpleAdapter：

List<Map<String, String>> data = new ArrayList<>(); for (String item : yourDataList) {     Map<String, String> map = new HashMap<>();     map.put("text", item);     data.add(map); }  SimpleAdapter adapter = new SimpleAdapter(this, data, android.R.layout.simple_spinner_item, new String[] {"text"}, new int[] {android.R.id.text1}); adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); spinner.setAdapter(adapter); 

3. 使用 BaseAdapter：

BaseAdapter adapter = new BaseAdapter() {     @Override     public int getCount() {         return yourDataList.size();     }      @Override     public Object getItem(int position) {         return yourDataList.get(position);     }      @Override     public long getItemId(int position) {         return position;     }      @Override     public View getView(int position, View convertView, ViewGroup parent) {         if (convertView == null) {             LayoutInflater inflater = LayoutInflater.from(parent.getContext());             convertView = inflater.inflate(android.R.layout.simple_spinner_item, parent, false);         }          TextView textView = convertView.findViewById(android.R.id.text1);         textView.setText(yourDataList.get(position));          return convertView;     } };  adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); spinner.setAdapter(adapter); 

以上是几种常见的动态加载 Spinner 数据的方法，根据具体需求选择适合的方法。
