在我使用SherlockActivity与我不同的方法之前，我将所有治疗都包括在内并且走路正确SherlockFragmentActivity。DrawerMenu但我决定改变SherlockActivity以SherlockFragment从DrawerMenu所有观点中受益。我尝试了第一次Activity，Fragment它出现了，但包含数据库数据的列表没有出现。请帮帮我。

我的适配器类

public class ListAdapterAnSco extends BaseAdapter {

    // Declare Variables
    Context mContext;
    LayoutInflater inflater;
    private List<AnSco> listAnsco = null;
    private ArrayList<AnSco> arraylist;
    ListAnSco anscoList;

    public ListAdapterAnSco(Context context, List<AnSco> listAnsco) {
        mContext = context;
        this.listAnsco = listAnsco;
        inflater = LayoutInflater.from(mContext);
        this.arraylist = new ArrayList<AnSco>();
        this.arraylist.addAll(listAnsco);
    }

    public class ViewHolder {
        TextView an;
    }

    @Override
    public int getCount() {
        return listAnsco.size();
    }

    @Override
    public AnSco getItem(int position) {
        return listAnsco.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(final int position, View view, ViewGroup parent) {
        final ViewHolder holder;
        if (view == null) {
            holder = new ViewHolder();
            view = inflater.inflate(R.layout.annee_sco_item, null);
            // Locate the TextViews in listview_item.xml
            holder.an = (TextView) view.findViewById(R.id.an_item);
            view.setTag(holder);
        } else {
            holder = (ViewHolder) view.getTag();
        }
        // Set the results into TextViews
        holder.an.setText(listAnsco.get(position).getAnsco());
        view.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {
                // Send single item click data to SingleItemView Class
                Intent intent = new Intent(mContext, ListPeriode.class);
                // Pass all data rank
                intent.putExtra("ANSCO_ID",(listAnsco.get(position).getIdan()));
                // Pass all data country
                intent.putExtra("ANSCO_AN",(listAnsco.get(position).getAnsco()));
                // Start SingleItemView Class
                mContext.startActivity(intent);
            }
        });

        view.setOnLongClickListener(new OnLongClickListener() {

            @Override
            public boolean onLongClick(View v) {
                int idAn = (listAnsco.get(position).getIdan());
                String annee = (listAnsco.get(position).getAnsco());
                AnSco ansco=new AnSco(idAn,annee);
                AlertDialog diag= Alerts.ShowEditDialogAnSco(mContext,ansco);
                diag.setOnDismissListener(new OnDismissListener() {

                @Override

                    notifyDataSetChanged();
                }
            });
            diag.show();

                return false;
            }
        });
        return view;
    }

    // Filter Class
    public void filter(String charText) {
        charText = charText.toLowerCase(Locale.getDefault());
        listAnsco.clear();
        if (charText.length() == 0) {
            listAnsco.addAll(arraylist);
        } 
        else 
        {
            for (AnSco wp : arraylist)

我的代码中的一切都是正确的。除了颜色。事实上，@drawable/background1witch is my List 的背景颜色与@color/font_colorwitch is my list Items 的颜色相同。
