Question

我想在我的Android应用程序中为主片段添加一个viewPager。

这是主片段

的xml文件

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">

        <ListView
            android:id="@android:id/list"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />

</RelativeLayout>

这是Main Fragment的Java代码

public class MainFragment extends ListFragment {

    private static final String TAG = MainFragment.class.getSimpleName();
    private StudentsDBHandler studentsDBHandler;

    public MainFragment() {
    }

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        studentsDBHandler = new StudentsDBHandler(getActivity());
        View rootView = inflater.inflate(R.layout.main_fragment, container, false);
        displayStudents();
        return rootView;
    }

    private void displayStudents() {
        List<Student> studentList = studentsDBHandler.getAll();
        ArrayAdapter<Student> list = new ArrayAdapter<>(getActivity(), R.layout.item_student, studentList);
        setListAdapter(list);
    }
}

你有一个DrawerLayout页面。这是关于你的抽屉包含。在DrawerLayout XML

<android.support.v4.widget.DrawerLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

在下面添加此代码

<android.support.v4.view.ViewPager
            android:id="@+id/viewpager"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent" />

编写此代码并设置您的View pager示例

        viewPager=(ViewPager)findViewById(R.id.viewPager);

        FragmentManager fm=getSupportFragmentManager();

        viewPager.setAdapter(new MyAdapter(fm));


    }

    class MyAdapter extends FragmentPagerAdapter{
        public MyAdapter(FragmentManager fm) {
            super(fm);
        }

        @Override
        public Fragment getItem(int position) {



            if(position==0)
                fragment= new Home1();




            if(position==1)
                fragment=new Home2();
            return fragment;
        }

        @Override
        public int getCount() {
            return 2;
        }
    }

}
