Question

在我的项目中，我有一个使用导航器打开/导航到不同屏幕（片段）的活动，我最初打开了一个片段，将其视为主屏幕。我在导航抽屉中使用了listview，这样如果我点击列表视图中的任何项目，它应该替换该活动上的片段....我在listview的项目点击上替换片段时遇到问题。我的主要活动课程：

public class Main extends Activity {
    DrawerLayout drawerlayout;
    ListView LVdrawer;
    ImageView toplogo;
    View rL;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        FragmentManager FM = getFragmentManager();
        final FragmentTransaction Trans = FM.beginTransaction();
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.navigation_drawer);
        final ActionBar actionBar = getActionBar();
        rL = findViewById(R.id.toplogoaction);
        drawerlayout = (DrawerLayout) findViewById(R.id.drawer_layout);
        LVdrawer = (ListView) findViewById(R.id.left_drawer);
        LVdrawer.setAdapter(new CustomAdapter(this, 0));
        Trans.setCustomAnimations(R.anim.actionbarin, R.anim.actionbarout, R.anim.actionbarin, R.anim.actionbarout);
        Trans.add(R.id.content_frame, new CreatenBuy(), "AddAppsF");
        Trans.commit();
        LVdrawer.setOnItemClickListener(new OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> parent, View view,
                    int position, long id) {
                // TODO Auto-generated method stub
                TextView ttt=(TextView) view.findViewById(R.id.detail);
                String s=(String) ttt.getText();
                Trans.replace(R.id.content_frame, new CreatenBuy(), "addappsF");

            Trans.commit();

            }
        });
    }
}

我的Fragmnetclass：

    public class CreatenBuy extends Fragment {
        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                Bundle savedInstanceState) {
            // TODO Auto-generated method stub
            View page=inflater.inflate(R.layout.createnbuy, container, false);
            return page;
        }

}

logcat的：
