Android AsyncTask等待完成检索数据并将其显示在ListView中

public class MyAsyncTask extends AsyncTask<Void, Void, List<String>> {

    private Context mContext;
    private ListView mListView;
    private ProgressDialog mProgressDialog;

    public MyAsyncTask(Context context, ListView listView) {
        mContext = context;
        mListView = listView;
    }

    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        // 在任务执行前显示进度对话框
        mProgressDialog = ProgressDialog.show(mContext, "Loading", "Please wait...");
    }

    @Override
    protected List<String> doInBackground(Void... voids) {
        // 执行耗时操作，例如从网络获取数据
        List<String> data = fetchDataFromServer();
        return data;
    }

    @Override
    protected void onPostExecute(List<String> data) {
        super.onPostExecute(data);
        // 隐藏进度对话框
        mProgressDialog.dismiss();
        // 更新UI，将数据显示在ListView中
        ArrayAdapter<String> adapter = new ArrayAdapter<>(mContext, android.R.layout.simple_list_item_1, data);
        mListView.setAdapter(adapter);
    }

    private List<String> fetchDataFromServer() {
        // 执行网络请求，获取数据
        // 这里只是一个示例，实际情况需要根据具体需求实现
        List<String> data = new ArrayList<>();
        data.add("Item 1");
        data.add("Item 2");
        data.add("Item 3");
        return data;
    }
}

ListView listView = findViewById(R.id.list_view);
MyAsyncTask task = new MyAsyncTask(this, listView);
task.execute();
