特定孩子已经有父母

Question

我想创建一个动态布局，但我有错误

  

指定的孩子已经有父母。您必须首先在孩子的父母身上调用removeView（）。

我在Stackoverlow上发现了一些东西，但最重要的是建议使用我已经使用的这一行：

  

查看rootView = inflater.inflate（R.layout.fragment_item，container，false）;

任何解决方案??

ItemFragment.java

 @Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.fragment_items, container, false);
    layout = (TableLayout) rootView.findViewById(R.id.itmes_fragment_layout);      

    item_folder_button = new Button(getActivity());
    item_folder_button = (Button) rootView.findViewById(R.id.items_button_layout);
return rootView;
}

private void createItemsButtons() {       

    layout.removeAllViews();

    if (itemscontainer.length == 0) {
        TableRow row = new TableRow(myContext);
        TextView no_items = new TextView(myContext);
        no_items.setText(getResources().getString(R.string.no_items));
        no_items.setTextSize(35);
        row.addView(no_items);
        layout.addView(row);
    } else {
        for (int i = 0; i <= itemscontainer.length; ) {
            TableRow tableRow = new TableRow(getActivity());
            TableRow.LayoutParams param = new TableRow.LayoutParams(
                    TableRow.LayoutParams.MATCH_PARENT,
                    TableRow.LayoutParams.WRAP_CONTENT, 1.0f);
            tableRow.setLayoutParams(param);
            tableRow.setGravity(Gravity.CENTER_VERTICAL);
            for (int y = 0; (y < 3) && (i <= itemscontainer.length); y++) {
                item_folder_button.setText(("Text " + i));                    
                item_folder_button.setVisibility(View.VISIBLE);
                item_folder_button.setGravity(Gravity.CENTER);
                TableRow.LayoutParams par = new TableRow.LayoutParams(y);
                item_folder_button.setLayoutParams(par);
                int id = i;
                item_folder_button.setId(id);
                item_folder_button.setOnClickListener(new View.OnClickListener() {
                    public void onClick(View v) {
                        int btn_selected = item_folder_button.getId();
                        Fragment fragment = new ItemFragment();
                        if (fragment != null) {
                            FragmentManager fragmentManager = myContext.getSupportFragmentManager();
                            FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
                            fragmentTransaction.replace(R.id.container_body, fragment).addToBackStack(null);
                            fragmentTransaction.commit();
                        }
                    }
                });
                tableRow.addView(item_folder_button);
                i++;
            }
            layout.removeView(layout.getRootView());
            layout.addView(tableRow);
        }
    }
}
    return rootView;
}
