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：

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);

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);

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。
