public class SchedulingFragment extends android.support.v4.app.Fragment {

    Spinner spinner;
    Spinner spinner2;
    ArrayAdapter<CharSequence> adapter;
    Button proxBtn;


    public SchedulingFragment() {
        // Required empty public constructor
    }




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

        View v = inflater.inflate(R.layout.fragment_scheduling, container, false);

        String[] values =
                {"2015","2014","2013","2012","2011"};
        Spinner spinner = (Spinner) v.findViewById(R.id.spinner);
        ArrayAdapter<String> LTRadapter = new ArrayAdapter<String>(this.getActivity(),R.layout.spinner_center_item, values);
        LTRadapter.setDropDownViewResource(R.layout.spinner_center_item);
        spinner.setAdapter(LTRadapter);

        String[] values2 =
                {"CHEVROLET"};
        Spinner spinner2 = (Spinner) v.findViewById(R.id.spinner2);
        ArrayAdapter<String> LTRadapter2 = new ArrayAdapter<String>(this.getActivity(),R.layout.spinner_center_item, values2);
        LTRadapter2.setDropDownViewResource(R.layout.spinner_center_item);
        spinner2.setAdapter(LTRadapter2);

        String[] values3 =
                {"CAPTIVA", "CELTA", "CLASSIC", "COBALT", "CRUZE", "MONTANA", "ONIX", "S10", "PRISMA"};
        Spinner spinner3 = (Spinner) v.findViewById(R.id.spinner3);
        ArrayAdapter<String> LTRadapter3 = new ArrayAdapter<String>(this.getActivity(),R.layout.spinner_center_item, values3);
        LTRadapter3.setDropDownViewResource(R.layout.spinner_center_item);
        spinner3.setAdapter(LTRadapter3);

        String[] values4 =
                {"1.8 Ecotec 6 - 4 Portas LT"};
        Spinner spinner4 = (Spinner) v.findViewById(R.id.spinner4);

Answer 1

使用FragmentTransaction。

您的点击：

@Override
            public void onClick(View v) {
                switch (v.getId()) {
                case R.id.btnSearch:

                   FragmentManager fm = getFragmentManager();
                   FragmentTransaction ft = fm.beginTransaction();
                   ft.replace(R.id.show_fragment, new TestFragment(), "fragment_screen");
                    ft.commit();
                 break;
                }
            }

yourfile.xml：

<FrameLayout
        android:id="@+id/show_fragment"
        android:layout_width="match_parent"
        android:layout_height="0dp">

    </FrameLayout>

Answer 2

Fragment newFragment = new ProductListFragment();
FragmentTransaction transaction = getFragmentManager().beginTransaction();
transaction.replace(R.id.content_frame, newFragment);
transaction.addToBackStack(null);
transaction.remove(newFragment).commit();
