Question

我正在尝试合并或连接通过python循环生成的表。这就是我所拥有的：

<h:form>
    <h:inputText valueChangeListener="#{bean.onNewValue}" value="#{bean.value}">
        <f:ajax event="keyup" render="@form" execute="@form"/>
    </h:inputText>
</h:form>

基本上，我想添加到与请求表具有相同列的原始request1表中，但是，我得到一个错误： “您正在尝试合并object和float64列。如果要继续，则应使用pd.concat。”

您可能想使用public class MainActivity extends Activity {GridView grid; String url="http://dstreet.site/"; String link,title,src; ArrayList list= new ArrayList(); @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Scrapper(); grid = (GridView)findViewById(R.id.grid); grid.setAdapter(new ImageAdapter(this, list)); } public class ImageAdapter extends BaseAdapter { ArrayList list; private LayoutInflater inflater; Context c; int mCount; ImageAdapter(Context context, ArrayList list) { inflater = LayoutInflater.from(context); c = context; mCount = list.size(); this.list=list; } @Override public int getCount() { return mCount; } @Override public Object getItem(int position) { return true; } @Override public long getItemId(int position) { return position; } @Override public View getView(int position, View convertView, ViewGroup parent) { final ViewHolder holder; View view = convertView; if (view == null) { view = inflater.inflate(R.layout.img, parent, false); holder = new ViewHolder(); assert view != null; holder.imageView = (ImageView) view.findViewById(R.id.image); view.setTag(holder); } else { holder = (ViewHolder) view.getTag(); } Picasso.get() .load(list.get(position)) .placeholder(R.drawable.ic_launcher) .error(R.drawable.ic_launcher) .fit() .into(holder.imageView, new Callback() { @Override public void onError(Exception p1) {holder.imageView.setVisibility(View.INVISIBLE); // TODO: Implement this method } @Override public void onSuccess() { holder.imageView.setVisibility(View.VISIBLE); } }); return view; } } static class ViewHolder { ImageView imageView; } public void Scrapper() { Content content= new Content(); content.execute(); } public class Content extends AsyncTask<Void,Void,Void> { @Override protected Void doInBackground(Void[] p1) { // TODO: Implement this method try { Document doc = Jsoup.connect(url).get(); // Identify Table Class "worldpopulation" for (Element table : doc.select("div[class=poster]")) { Elements imgSrc = table.select("img[src]"); // Get only src from img src src = imgSrc.attr("src"); list.add(src); } Log.d("image links",list.toString()); } catch (IOException e) {e.printStackTrace(); } return null; } }}

concat

循环合并请求的表
