如何在片段中动态添加TableRow？ [英] How to dynamically add a TableRow in a Fragment?

问题描述

我在Android编程中是新的，目前我正试图以片段动态地在表格布局中插入一个textview。它在将类扩展到Activity时工作。以下是我的代码段。我缺少什么吗？

  public View onCreateView（LayoutInflater inflater，ViewGroup容器，Bundle savedInstanceState）{
查看视图= inflater.inflate（R.layout.fragment_schedule，null）; 
 TableLayout ll =（TableLayout）getActivity（）。findViewById（R.id.tableLayout1）; 
 TableRow tr = new TableRow（getActivity（））; 
 TextView tv1 = new TextView（getActivity（））; 
 tv1.setText（TEST NUMBER）; 
 tv1.setTextColor（Color.WHITE）; 
 tv1.setTextSize（20）; 
 tv1.setPadding（5，5，5，5）; 
 tr.addView（tv1）; 
 ll.addView（tr）; 
返回视图; 
} 
  

提前谢谢。

解决方案

你必须给出view.findViewById，
，因为你在视图中添加了。

  TableLayout ll =（TableLayout）view.findViewById（R.id.tableLayout1）;

I am new in Android programming, currently I am trying to insert a textview inside the table layout dynamically in fragment. It worked while extending the class to Activity. Below is my code snippet. Am I missing something?

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_schedule, null);
    TableLayout ll = (TableLayout) getActivity().findViewById(R.id.tableLayout1);
    TableRow tr= new TableRow(getActivity());
    TextView tv1 = new TextView(getActivity());
    tv1.setText("TEST NUMBER");
    tv1.setTextColor(Color.WHITE);
    tv1.setTextSize(20);
    tv1.setPadding(5, 5, 5, 5);
    tr.addView(tv1);
    ll.addView(tr);
    return view;
}

Thank you in advance.

解决方案

you have to give view.findViewById, because you are adding that in the view.

TableLayout ll = (TableLayout) view.findViewById(R.id.tableLayout1);
