java安卓表格布局。addView（）实际上不起作用

Question

我试图用addView方法用一些视图填充我的TableLayout

这就是我试图做的：

private void createNewTable(){

  tableLayout = (TableLayout) getView().findViewById(R.id.tableLayout1);
  for(int i = 0; i < objectList.size(); i++){
            if(objectList.get(i).getType() == 0){
                tableLayout.addView(createLocationObjectInTable((LocationObject)objectList.get(i)), i);
            }
  }
}

以及createObjectInList方法：

private View createLocationObjectInTable(LocationObject locObject) {

    TableRow tr = new TableRow(getActivity());
    View v = LayoutInflater.from(getActivity()).inflate(R.layout.view_layout, tr, false);

    TextView textViewCityName = (TextView) v.findViewById(R.id.textView_City_Name);
    TextView textViewCityProvider = (TextView) v.findViewById(R.id.textView_City_Provider);
    textViewCityName.setText(locObject.getTitle());
    textViewCityProvider.setText(locObject.getSubTitle());

    return v;
}

但是视图不会显示在tableLayout中。Logcat没有给我任何错误信息，当我试图在电话线后做事情时

tableLayout.addView(createLocationObjectInTable((LocationObject)objectList.get(i)), i);

什么都没发生。在这一行之后，应用程序什么也不做

希望有人能告诉我我的错误

您不需要将视图添加到TableRow，只需将视图添加到TableLayout。试试这个：

private View createLocationObjectInTable(LocationObject locObject) {
    ...
    textViewCityProvider.setText(locObject.getSubTitle());

    tr.addView(v);
    return tr;

}
