如何在AsyncTask中为ConstraintLayout添加新的ImageView？

public class MyAsyncTask extends AsyncTask<Void, Void, Bitmap> {
    private ConstraintLayout constraintLayout;
    private Context context;

    public MyAsyncTask(ConstraintLayout constraintLayout, Context context) {
        this.constraintLayout = constraintLayout;
        this.context = context;
    }

    @Override
    protected Bitmap doInBackground(Void... voids) {
        // 执行耗时操作，例如从网络加载图片数据
        // 返回加载的图片数据
        return loadBitmapFromNetwork();
    }

    @Override
    protected void onPostExecute(Bitmap bitmap) {
        super.onPostExecute(bitmap);
        // 在主线程中执行UI操作
        ImageView imageView = new ImageView(context);
        imageView.setLayoutParams(new ConstraintLayout.LayoutParams(
                ConstraintLayout.LayoutParams.WRAP_CONTENT,
                ConstraintLayout.LayoutParams.WRAP_CONTENT));
        constraintLayout.addView(imageView);

        // 设置ImageView的内容为加载的图片数据
        imageView.setImageBitmap(bitmap);
    }

    private Bitmap loadBitmapFromNetwork() {
        // 从网络加载图片数据的具体实现
        return null;
    }
}
