Ich habe meine Anwendung mit Navigation Drawer erstellt. Ich In meiner Tätigkeit setzen diesen Code:Wie setze ich dieses Element in die Symbolleiste?
public class MenuActivity extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener
{
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_menu);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close)
{
public void onDrawerOpened(View view)
{
super.onDrawerOpened(view);
}
public void onDrawerClosed(View v)
{
super.onDrawerClosed(v);
}
};
drawer.setDrawerListener(toggle);
toggle.syncState();
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
onNavigationItemSelected(navigationView.getMenu().getItem(0));
navigationView.setNavigationItemSelectedListener(this);
}
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu, menu);
return true;
}
public boolean onOptionsItemSelected(MenuItem item)
{
int id = item.getItemId();
if (id == R.id.action_settings)
{
return true;
}
return super.onOptionsItemSelected(item);
}
public boolean onNavigationItemSelected(MenuItem item) {
Fragment fragment = null;
String title = null;
int id = item.getItemId();
Class fragmentClass=null;
if (id == R.id.Home)
{
fragmentClass = HomeFragment.class;
title="Home";
}
else if (id == R.id.Profile)
{
fragmentClass= ProfileFragment.class;
title="Profile";
}
try {
fragment = (Fragment) fragmentClass.newInstance();
} catch (InstantiationException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
}
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction().replace(R.id.content_frame, fragment).commit();
if (getSupportActionBar() != null)
{
getSupportActionBar().setTitle(title);
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
jetzt in der HomeFragment ich eine Registerkarte im unteren Bereich des Bildschirms platzieren wollen. Also habe ich diesen Code:
public class HomeFragment extends Fragment {
public static TabLayout tabLayout;
public static ViewPager viewPager;
public static int int_items = 3 ;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View inflatedView = inflater.inflate(R.layout.fragment_home, null);
tabLayout = (TabLayout) inflatedView.findViewById(R.id.tabs);
viewPager = (ViewPager) inflatedView.findViewById(R.id.viewpager);
viewPager.setAdapter(new MyAdapter(getChildFragmentManager()));
tabLayout.post(new Runnable() {
@Override
public void run() {
tabLayout.setupWithViewPager(viewPager);
}
});
return inflatedView;
}
class MyAdapter extends FragmentPagerAdapter {
public MyAdapter(FragmentManager fm) {
super(fm);
}
/**
* Return fragment with respect to Position .
*/
@Override
public Fragment getItem(int position)
{
switch (position){
case 0 : return new SearchFragment();
case 1 : return new CardFragment();
case 2 : return new MapFragment();
}
return null;
}
public int getCount() {
return int_items;
}
Aber schließlich erhalte ich dieses Ergebnis:
Ich möchte, dies zu tun:
- setzen diese tablayout in der Symbolleiste
- Setzen Sie diese in den Boden der Bildschirm
Wie könnte ich es tun?
