android - 如何在 Android ListView 为空时隐藏页脚？

Question

我有一个 ListView ，其中的项目是从服务器加载的，并且在 listview 中有一个页脚，问题是当没有项目时，即 ListView 是空的，用户可以看到页脚。我是什么想要如果 listview 中没有项目，则用户看不到页脚。我该怎么做，请帮助我。

我将不胜感激。

这是我的代码:-

protected void onPostExecute(final String result) {

        m_ProgressView.setVisibility(View.GONE);
        try {
            m_oResponseobject = new JSONObject(result);// getting response from server
            JSONArray posts = m_oResponseobject.optJSONArray("dealList");


            for (int i = 0; i < posts.length(); i++) {
                JSONObject post = posts.getJSONObject(i);
                item = new CDealAppDatastorage();
                item.setM_szHeaderText(post.getString("dealname"));
                item.setM_szsubHeaderText(post.getString("dealcode"));
                item.setM_n_Image(m_n_FormImage[i]);
                s_oDataset.add(item);

            }

            // LoadMore button
            Button btnLoadMore = new Button(getActivity());
            btnLoadMore.setText("LOAD MORE DEALS");
            btnLoadMore.setBackgroundResource(R.drawable.button_boarder);
            btnLoadMore.setTextAppearance(getActivity(), android.R.style.TextAppearance_DeviceDefault_Small);
            btnLoadMore.setTextColor(Color.WHITE);
            btnLoadMore.setGravity(Gravity.CENTER);



            // Adding Load More button to lisview at bottom
            m_ListView.addFooterView(btnLoadMore);
            m_oAdapter = new CDealAppListingAdapter(getActivity(), s_oDataset);// create adapter object and add arraylist to adapter
            m_ListView.setAdapter(m_oAdapter);//adding adapter to recyclerview
            m_oAdapter.notifyDataSetChanged();
            }

像这样隐藏你的页脚:

// Firs check the list size is greater than 0:

if(s_oDataset.size > 0)
{
 // Add your footer here

}else
{
 // Dont not add your footer or Hide your footer
}
