AsyncTask在BaseAdapter中更改ViewGroup属性(ListAdapter)

public class MyAsyncTask extends AsyncTask<Void, Void, Void> {
    private ViewGroup viewGroup;
    private int newLayoutParams;

    public MyAsyncTask(ViewGroup viewGroup, int newLayoutParams) {
        this.viewGroup = viewGroup;
        this.newLayoutParams = newLayoutParams;
    }

    @Override
    protected void onPreExecute() {
        // 在执行耗时操作前的准备工作，可以在这里显示进度条等UI操作
    }

    @Override
    protected Void doInBackground(Void... voids) {
        // 执行耗时操作，例如更改ViewGroup属性
        viewGroup.setLayoutParams(newLayoutParams);
        return null;
    }

    @Override
    protected void onPostExecute(Void aVoid) {
        // 在耗时操作完成后更新UI，将更改后的ViewGroup属性应用到相应的视图上
        notifyDataSetChanged(); // 如果需要刷新列表视图
    }
}

MyAsyncTask myAsyncTask = new MyAsyncTask(viewGroup, newLayoutParams);
myAsyncTask.execute();
