Adding Tabs to Fragment of navigationDrawer

Adding Tabs to Fragment of navigationDrawer - android

So i know there have been plenty of answered questions about my problem, but i dont know why its not working
The Navigation drawer is working as intenden but im struggling with implementing the tabs. When i created the project i selected the drawer activity at the start if this helps
thx for the help
Sooo, i cleaned up the code and implemented the newer version, for future problems i will post all my code
This ist the Main Activity
package com.example.myapplicationteeeeeeeeeest;
import android.os.Bundle;
import com.google.android.material.floatingactionbutton.FloatingActionButton;
import com.google.android.material.snackbar.Snackbar;
import android.view.View;
import androidx.navigation.NavController;
import androidx.navigation.Navigation;
import androidx.navigation.ui.AppBarConfiguration;
import androidx.navigation.ui.NavigationUI;
import com.google.android.material.navigation.NavigationView;
import androidx.drawerlayout.widget.DrawerLayout;
import androidx.appcompat.app.AppCompatActivity;
import androidx.appcompat.widget.Toolbar;
import android.view.Menu;
public class MainActivity extends AppCompatActivity {
private AppBarConfiguration mAppBarConfiguration;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate( savedInstanceState );
setContentView( R.layout.activity_main );
Toolbar toolbar = findViewById( R.id.toolbar );
setSupportActionBar( toolbar );
FloatingActionButton fab = findViewById( R.id.fab );
fab.setOnClickListener( new View.OnClickListener() {
#Override
public void onClick(View view) {
Snackbar.make( view, "Replace with your own action", Snackbar.LENGTH_LONG )
.setAction( "Action", null ).show();
}
} );
DrawerLayout drawer = findViewById( R.id.drawer_layout );
NavigationView navigationView = findViewById( R.id.nav_view );
// Passing each menu ID as a set of Ids because each
// menu should be considered as top level destinations.
mAppBarConfiguration = new AppBarConfiguration.Builder(
R.id.nav_home, R.id.nav_gallery, R.id.nav_slideshow,
R.id.nav_tools, R.id.nav_share, R.id.nav_send )
.setDrawerLayout( drawer )
.build();
NavController navController = Navigation.findNavController( this, R.id.nav_host_fragment );
NavigationUI.setupActionBarWithNavController( this, navController, mAppBarConfiguration );
NavigationUI.setupWithNavController( navigationView, navController );
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate( R.menu.main, menu );
return true;
}
#Override
public boolean onSupportNavigateUp() {
NavController navController = Navigation.findNavController( this, R.id.nav_host_fragment );
return NavigationUI.navigateUp( navController, mAppBarConfiguration )
|| super.onSupportNavigateUp();
}
}
The Layout for Main Activity

Android: Recyclerview inside fragment fetching data from TMDbApi gives error: E/RecyclerView: No adapter attached; skipping layout

I've been struggling with a problem on android. I have an app with a drawer which shows fragments depending on what menu item you click in the drawer.
Here's how my app currently works:
This is the drawer with the menu buttons:
Whenever I click a button, for instance Profile, it will load the correct Fragment:
Now I have this problem with the Recyclerview withing my fragmentview of TV Show
When I click on tv shows I get a white empty layout like this:
And this is what I get in the logcat:

And finally the layout files:

android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="#layout/nav_header"
app:menu="#menu/draw_menu" />
</android.support.v4.widget.DrawerLayout>
fragment_tvshow.xml which holds the recyclerview
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<android.support.v7.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/showsRecyclerView"/>
</RelativeLayout>
And shows_item.xml which represents 1 item in the recyclerviewlist
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal" android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:layout_width="0dp"
android:layout_height="50dp"
android:scaleType="fitCenter"
android:layout_margin="8dp"
android:layout_weight="1"
android:id="#+id/showImage"/>
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:id="#+id/showTitle"
android:text="Show Title"
android:textSize="22sp"
android:layout_weight="3"
android:layout_margin="22dp"/>
</LinearLayout>

I think it's because once your fragment's onCreate is first run, the recyclerView isn't assigned an adapter, it's until after you fetch your data (the tv shows) that you set the adapter to your recyclerView.
One way to fix this would be to have a constructor that doesn't take any arguments for your adapter, and a method inside it that would pass in whatever data the recyclerView will need to display. You'd end up with something like this:
public class ListAdapter {
public ListAdapter() {}
public void submitList(final List<TvShow> tvShows) {
this.tvShows = tvShows;
notifyDataChanged();
}
}

Fragment is not being replaced after click in navigation drawer

I tried every way to solve this problem but still I am not getting whats wrong with this code. Can you help me?

I want to REPLACE FRAGMENT WITH OTHER FRAGMENT WHEN I CLICK ON NAVIGATION DRAWER ITEMS
Can anyone help me?

I can support you giving you my working code for Android 27.1.1:
public class MainActivity extends AppCompatActivity implements
BottomNavigationView.OnNavigationItemSelectedListener {
private int mSelectedId;
/**
* Create Navigation bar and load the main fragment "statistics".
*/
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
loadFragment(new FragmentStatistics());
BottomNavigationView navigation = findViewById(R.id.navigation);
navigation.setOnNavigationItemSelectedListener(this);
mSelectedId = navigation.getSelectedItemId();
}
/**
* Checks for any event in the Navigation Bar.
* If the item selected is the same as the actual item
* Do nothing
* Else
* Load new fragment selected.
*/
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
Fragment fragment = null;
if (mSelectedId != item.getItemId()) {
mSelectedId = item.getItemId();
switch (item.getItemId()) {
case R.id.statistics:
fragment = new FragmentStatistics();
break;
case R.id.shops:
fragment = new FragmentShops();
break;
}
}
return loadFragment(fragment);
}
private boolean loadFragment(Fragment fragment) {
//switching fragment
if (fragment != null) {
getSupportFragmentManager()
.beginTransaction()
.replace(R.id.fragment_container, fragment)
.commit();
return true;
}
return false;
}
}
The rest of your code is exact as mine.

how can i open a fragment from gridview?

i want to open a fragment from MainActivity where i have gridview.i am new to android and this is the first time to use fragment.
this is my mainactivity:
package com.example.grasu.petrosani;
import android.content.Intent;
import android.support.annotation.NonNull;
import android.support.design.widget.NavigationView;
import android.support.design.widget.TabLayout;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentTransaction;
import android.support.v4.view.ViewPager;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.ThemedSpinnerAdapter;
import android.view.MenuItem;
import android.view.View;
import android.widget.AdapterView;
import android.widget.GridView;
public class MainActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener,AdapterView.OnItemClickListener{
private DrawerLayout DrawerLayout;
private NavigationView Drawer;
GridView gridview;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Drawer = findViewById(R.id.nav_view);
Drawer.setNavigationItemSelectedListener(this);
DrawerLayout = findViewById(R.id.drawer_layout);
CategoryAdapter adapter = new CategoryAdapter(this, getSupportFragmentManager());
gridview=findViewById(R.id.album_Gridview);
gridview.setAdapter(new GridViewAdapter(this));
}
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
return false;
}
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
if (parent.getId()==R.id.album_Gridview){
switch (position) {
case 0:
}
}
}
}
this is my xml for activity main:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<GridView
android:id="#+id/album_Gridview"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:layout_gravity="start"
android:fitsSystemWindows="true"
android:duplicateParentState="true"
app:menu="#menu/drawer_view"/>
</android.support.v4.widget.DrawerLayout>
and this is the fragment i want to open from gridview:
package com.example.grasu.petrosani;
import android.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class InfoFragment extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.info, container, false);
return rootView;
}}
i tried with FragmentManager fm = getSupportFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
ft.replace(CurrentClass.this, MainActivity.class); but it didn't work.do I have to modify my mainactivity to extend fragmentActivity?

You can try something like -
Create a New Activity.
Add your Fragment in the above created Activity.
In your GridView Item click, open the New Activity via an Intent like - startActivity(new Intent(MainActivity.this, NewActivity.class));

Follow below code:
FragmentTransaction fragmentTransaction = getSupportFragmentManager()
.beginTransaction();
Fragment profileFragment = new InfoFragment();//the fragment you want to show
profileFragment.setArguments(bundle);
fragmentTransaction
.replace(R.id.content_frame, profileFragment);//R.id.content_frame is the layout you want to replace
fragmentTransaction.addToBackStack(null);
fragmentTransaction.commit();

Android Fragment ViewPager Is Recreating Options Menu

I am making an android app which has a navigation drawer with fragments being loaded on navigation items.
One of the fragment is containing two tabs which is loading another two fragments via ViewPager.
Everything is working fine as expectations but the problem comes when I select another navigation item from drawer.
One of the tab has options menu but when I go to another fragment and comes back to the earlier, then options menu gets duplicated.

Had to use this code in each fragment in the way to the navigation action where I don't need the options bar

You can't use a Linearlayout to store your fragments, its needs to be a Framelayout where you need to add the fragments
This is how I always setup my Navigation Drawer:
