How to make navigation drawer work in all fragments?

Question

Java

I have a main activity which has a navigation drawer:

public class MainActivity extends ActionBarActivity {



    private String[] mScreenTitles;
    private DrawerLayout mDrawerLayout;
    private ListView mDrawerList;

    private ActionBarDrawerToggle mDrawerToggle;
    private CharSequence mDrawerTitle;
    private CharSequence mTitle;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mTitle = mDrawerTitle = getTitle();
        mScreenTitles = getResources().getStringArray(R.array.screen_array);
        mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
        mDrawerList = (ListView) findViewById(R.id.drawer_list);


        mDrawerList.setAdapter(new ArrayAdapter<String>(this,R.layout.nav_draw, mScreenTitles));


        mDrawerList.setOnItemClickListener(new DrawerItemClickListener());

        // Àêòèâèðóåì êíîïêó Home â ïàíåëè Action Bar:
        getSupportActionBar().setHomeButtonEnabled(true);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);

        mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,R.drawable.ic_drawer,
                R.string.drawer_open,
                R.string.drawer_close
        )

        {

            public void onDrawerOpened(View drawerView) {
                getSupportActionBar().setTitle(mDrawerTitle);
                supportInvalidateOptionsMenu();
            }


            public void onDrawerClosed(View view) {
                getSupportActionBar().setTitle(mTitle);
                supportInvalidateOptionsMenu();
            }
        };


        mDrawerLayout.setDrawerListener(mDrawerToggle);
        if (savedInstanceState == null) {
            selectItem(0);
        }
    }

    public void Click88(View view) {
        setContentView(R.layout.russia);
    }

    public void Click120(View view) {
        setContentView(R.layout.piter);
    }

    public void Click3(View view) {
        setContentView(R.layout.prigo);
    }

    public void Click4(View view) {
        setContentView(R.layout.sochi);
    }

    public void Click(View view) {
        setContentView(R.layout.so_bul);
    }





@Override
public boolean onOptionsItemSelected(MenuItem item) {
    if (mDrawerToggle.onOptionsItemSelected(item)) {
        return true;
    }

    // Íàñòðàèâàåì äåéñòâèå êíîïêè ïîèñêà:
    switch(item.getItemId()) {
        case R.id.action_search:

            // Ïîêàçûâàåì Toast ñîîáùåíèå î ïîèñêå:
            Toast.makeText(this, R.string.action_search, Toast.LENGTH_SHORT).show();
            return true;
        default:
            return super.onOptionsItemSelected(item);
    }
}

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {


        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.menu_main, menu);
        return super.onCreateOptionsMenu(menu);
    }

    @Override
    public boolean onPrepareOptionsMenu(Menu menu) {


    boolean drawerOpen = mDrawerLayout.isDrawerOpen(mDrawerList);
    menu.findItem(R.id.action_search).setVisible(!drawerOpen);
    return super.onPrepareOptionsMenu(menu);
}


    // Íàñòðàèâàåì ñëóøàòåëÿ íàæàòèé ïî ïóíêòàì ìåíþ ñïèñêà â Navigation Drawer:
    private class DrawerItemClickListener implements ListView.OnItemClickListener {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            selectItem(position);
        }
    }


    private void selectItem(int position) {
        Fragment fragment = null;
        switch (position) {
            case 0:
                fragment = new ScreenOne();
                break;
            case 1:
                fragment = new ScreenTwo();
                break;
            default:
                break;
        }


        if (fragment != null) {
            FragmentManager fragmentManager = getSupportFragmentManager();
            fragmentManager.beginTransaction().replace(R.id.frame_for_drawer, fragment).commit();


            mDrawerList.setItemChecked(position, true);
            setTitle(mScreenTitles[position]);
            mDrawerLayout.closeDrawer(mDrawerList);

        } else {

            Log.e(this.getClass().getName(), "Ïðîèçîøëà îøèáêà!");
        }
    }




    @Override
    public void setTitle(CharSequence title) {
        mTitle = title;
        getSupportActionBar().setTitle(mTitle);
    }


    @Override
    protected void onPostCreate(Bundle savedInstanceState) {
        super.onPostCreate(savedInstanceState);
        mDrawerToggle.syncState();
    }

    @Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
        mDrawerToggle.onConfigurationChanged(newConfig);
    }
}

In other snippets I added:

public class S extends Fragment {


    public S() {
    }

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


        View rootView = inflater.inflate(R.layout.s, container,
                false);


        return rootView;

    }
}

But the navigation drawer works only in the main fragments. That is, which are turned on when you click on the side menu. How can I make the curtain work in all fragments? It is visible in all fragments. But it does not extend.

Answer 1

In the activity, do this for each fragment (add a listener)

public class MainActivity extends AppCompatActivity
        implements YourNameFragment.OnFragmentInteractionListener

And in every fragment

public interface OnFragmentInteractionListener {
        void onFragmentInteraction(Uri uri);
    }

And in each fragment declare
private OnFragmentInteractionListener mListener;
