Question

我成功创建了一个带标签导航的项目，我可以从onCreate（）添加新标签，但我想从按钮添加新标签（在我动态生成的片段内）。

Fragment是Main（Activity）中的一个staic类，如果我对选项卡插入行进行注释，它会起作用：

/*Fragments set the layout of the tabs*/
public static class MenuFragmentTab extends SherlockFragment{

    private Context context;
    private byte position;

    public void initialize(Context context, byte position){
        this.context = context;
        this.position = position;
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){

        /*Create the Fragment layout so I can attach the handlers*/
        View overView = inflater.inflate(R.layout.menu_fragment, container, false);

        /*When I create the fragment I initialize the button listeners*/
        if(context != null){
            /*Close Main tab*/
            Button closeMainButton = (Button)overView.findViewById(R.id.main_close_btn);
            CloseMainHandler closeMain = new CloseMainHandler();
            closeMainButton.setOnClickListener(closeMain);

            /*Open a new Tab*/
            Button newTabButton = (Button)overView.findViewById(R.id.new_tab_btn);
            NewTabHandler newTab = new NewTabHandler();
            newTabButton.setOnClickListener(newTab);
        }
        return overView;
    }

    /*the button to open a new tab*/
    private class NewTabHandler implements View.OnClickListener{

        @Override
        public void onClick(View v) {

            /*get the info for the new tab*/
            View parent = (View)v.getParent();
            EditText newTabTitle = (EditText)parent.findViewById(R.id.new_tab_title);
            EditText newTabContent = (EditText)parent.findViewById(R.id.new_tab_content);

            //Toast.makeText(context, newTabTitle.getText(), Toast.LENGTH_LONG).show();

            /*add the info to the ArrayLists*/
            Main.titles.add(newTabTitle.getText().toString());
            Main.contents.add(newTabContent.getText().toString());

            /*initialize the new tab*/
            ActionBar.Tab newTab = Main.actionBar.newTab().setText(
                    Main.titles.get(Main.titles.size()-1)
            );

            ContentFragmentTab fragContent = new ContentFragmentTab();
            fragContent.initialize(
                    context,
                    (byte)(Main.titles.size()-1)
            );

            /*This gives back a compilation error because of non-static reference*/
            TabClickHandler newListener = new TabClickHandler(fragContent);
            newTab.setTabListener(newListener);

            Main.actionBar.addTab(newTab);
        }

    }

    /*the button to close the main tab*/
    /*This should be a public, static function in Main, to avoid code repetition*/
    private class CloseMainHandler implements View.OnClickListener{
        @Override
        public void onClick(View v) {
            Main.actionBar.removeTabAt(position);
        }
    }
};

我的问题是：我如何使这项工作？我可以删除标签甚至添加标签，我只能在绑定TabChangeListeners时遇到麻烦！任何帮助/提示将不胜感激！谢谢！

从“MenuFragmentTab”中移除“静态”并且它可以正常工作！虽然给出了警告，但是有非静态片段，所以我想这解决了这个问题。

Android：使用ActionBarSherlock动态添加标签
