Question

我需要在onItemClick方法中用另一个片段替换片段。这就是我想要的：

public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

        TipoRestaurante rteActual = (TipoRestaurante) adapter.getItem(position);
        String msg = "Has elegido el tipo " + rteActual.getNombre_tipo();
        Toast.makeText(getActivity(), msg, Toast.LENGTH_LONG).show();

        Fragment newFragment = new TabFragmentComer();
        FragmentTransaction transaction = getFragmentManager().beginTransaction();


        transaction.replace(R.id.containerView, newFragment);
        transaction.addToBackStack(null);


        transaction.commit();


    }

但我得到一个例外：

09-28 23:51:02.310  14895-14895/com.solinpromex.elpasojuarezexperience E/AndroidRuntime﹕ FATAL EXCEPTION: main

我到达活动的当前片段，如下所示：

if (menuItem.getItemId() == R.id.nav_item_comer) {
                     FragmentTransaction xfragmentTransaction = mFragmentManager.beginTransaction();
                     xfragmentTransaction.replace(R.id.containerView,new TabFragmentComerTiposRestaurante()).commit();
                 }

欢迎任何帮助

您的片段中应该有一个界面，如下所示：

public class MyFragment extends Fragment {

    private OnFragmentInteractionListener mListener;

    public MyFragment() {
    }


    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View view = ...;
        return view;
    }

    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

        TipoRestaurante rteActual = (TipoRestaurante) adapter.getItem(position);
        String msg = "Has elegido el tipo " + rteActual.getNombre_tipo();
        Toast.makeText(getActivity(), msg, Toast.LENGTH_LONG).show();

        Fragment newFragment = new TabFragmentComer();    

        if(mListener != null){
            mListener.onFragmentInteraction(newFragment);
        }


    }

    @Override
    public void onAttach(Activity activity) {
        super.onAttach(activity);
        try {
            mListener = (OnFragmentInteractionListener) activity;
        } catch (ClassCastException e) {
            throw new ClassCastException(activity.toString()
                    + " must implement OnFragmentInteractionListener");
        }
    }

    @Override
    public void onDetach() {
        super.onDetach();
        mListener = null;
    }

    public interface OnFragmentInteractionListener {
        public void onFragmentInteraction(Fragment fragment);
    }

}

您的活动应该实现该界面：

MyActivity extends Activity implements OnFragmentInteractionListener{
//your activity methods...

@Override
    public void onFragmentInteraction(Fragment fragment) {
         //here you have that fragment and can change it with transactions
         FragmentTransaction transaction = getFragmentManager().beginTransaction();

        transaction.replace(R.id.containerView, fragment);
        transaction.addToBackStack(null);
        transaction.commit();
    }
}

将对象传递给另一个片段：

如果片段只是您在上面作为newFragment创建的片段，则可以按如下方式向其添加参数：

Fragment newFragment = new TabFragmentComer();
Bundle args = new Bundle();
args.putInt("myIntLabel", 2);
args.putString("myStringLabel", "my sample string");
//and you can add all you want to that bundle like this
newFragment.setArguments(args);

然后在你的片段onCreateView或onCreate方法中你可以得到这样的包：

...
Bundle args = getArguments();
int myInt = args.getInt("myIntLabel", (int defaultValue)); // returns 2
int myString  = args.getString("myStringLabel", (String defaultString)); // returns "my sample string"

如果您没有在此片段中创建片段，则可以将该接口方法的另一个参数添加为Bundle args，并将该包添加到您创建的片段中，如下所示：fragment.setArguments(args)

尝试关注替换片段。

        Products_Fragment df = new Products_Fragment();//this is your fragment.
        FragmentManager fm = getFragmentManager();
        FragmentTransaction ft = fm.beginTransaction();
        ft.replace(R.id.content_frame, df);
        ft.commit();
