Navigation Drawer not navigating - java

I have create a navigation drawer, i don't want to use fragments but instead activities. I have added this code which was working in many tutorials that i have watched.
public boolean onNavigationItemSelected( MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
switch (id) {
case R.id.Daily: {
Intent h= new Intent(goals.this, Daily.class );
startActivity(h);
break;
}
}
//close navigation drawer
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawerLayout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
Whenever i click on the page i would like to navigate to. The drawer closes and nothing else happens. I am just a beginner so i don't know how to proceed. I have watched about 10 tutorials and this is what they say work but it doesn't and i am not sure why. The onNavigationItemSelected method has a grey line under it, saying that the method has no been used.

}
#Override

Goals activity java:
package com.example.mitchell.tfit;
import android.content.Intent;
import android.os.Bundle;
import android.support.design.widget.NavigationView;
import android.support.v4.view.GravityCompat;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.ActionBarDrawerToggle;
import android.support.v7.app.AppCompatActivity;
import android.view.MenuItem;
public class goals extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener{
private DrawerLayout mDrawerLayout;
private ActionBarDrawerToggle mToggle;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_goals);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawerLayout);
mToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.string.open, R.string.close);
mDrawerLayout.addDrawerListener(mToggle);
mToggle.syncState();
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}

Your Activity needs to implement NavigationView.OnNavigationItemSelectedListener and you have to set the listener for your NavigationDrawer. Something like this should work:
public class MainActivity extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener{
#Override
protected void onCreate(Bundle savedInstanceState) {
// ...
NavigationView navigationView = findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
// rest of code
}
}
EDIT:
The NavigationViewer in the XML of your GoalsActivity should look like this:
<android.support.design.widget.NavigationView
android:id="navigationView"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#414E68"
app:itemIconTint="#FFFFFF"
app:headerLayout="#layout/header_profile"
app:itemTextColor="#android:color/background_light"
app:menu="#menu/drawermenu">
Furthermore, add this to your GoalsActivity.java, inside the onCreate() method:
NavigationView navigationView = findViewById(R.id.navigationView);
navigationView.setNavigationItemSelectedListener(this);

Why doesn't the replace function for fragments work?

I'm trying to open a Fragment from a Activity by using the fragmentManager.replace() function, but it doesn't do anything and the Logcat tells me nothing either. I have tried using both FragmentContainerView and FrameLayout inside my activity_main.xml, and even using the activity's ConstraintLayout ID to host the Fragment, but to no avail.
Here are the codes for my Activity that should open the fragment, and the fragment code itself:
OsActivity.java
import androidx.fragment.app.FragmentTransaction;
import android.os.Bundle;
import android.view.View;
import com.leonardomaito.autocommobile.fragments.NewOsFragment;
import autocommobile.R;
public class OsActivity extends AppCompatActivity {
NewOsFragment newOsFragment = new NewOsFragment();
private View v;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_os);
}
public void createNewOs(View view) {
FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();
fragmentTransaction.setReorderingAllowed(true);
fragmentTransaction.replace(R.id.osFragmentContainer, newOsFragment);
fragmentTransaction.addToBackStack(null);
fragmentTransaction.commit();
}
}
NewOsFragment.java
import android.os.Bundle;
import androidx.fragment.app.Fragment;
import androidx.fragment.app.FragmentTransaction;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import autocommobile.R;
public class NewOsFragment extends Fragment {
private Button btOsNext;
private Button btOsCancel;
private Fragment nextOs = new Fragment();
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_new_os, container, false);
btOsNext = view.findViewById(R.id.btNextOs);
btOsCancel = view.findViewById(R.id.btCancelNewOs);
return view;
}
public void nextOsStep(View view) {
FragmentTransaction fragmentManager = getActivity()
.getSupportFragmentManager()
.beginTransaction()
.replace(R.id.fragment_new_os, nextOs);
}
}

Shouldn't the replace function be opening my fragment on top of my activity? Is there something I'm doing wrong? The majority of other posts adressing this situation seemed to use .add instead of .replace, and were fixed by doing so.

Thanks for help I will try to repair it but don't know how.
This is very important to repair this for me. :)
Looks all good except textview1 color.
Add below line for the textview1 in layout xml

After clicking RUN button

Android actionbar/toolbar disappears after writing to edittext [duplicate]

This question already has answers here:
Android Toolbar moves up when keyboard appears
(17 answers)
Closed 4 years ago.
I'm stuck at this. I have an app where I have several pages made as fragments. Every page is good except the last one where when I tap on editText, action bar disappears and when I unfocus it, action bar didn't show up back.
I've tried changing appTheme to all kind of themes but they didn't change anything, most of them forced app to crash.
Here is my layout of that page

Thanks for taking time answering this. I am new in giving question here.
In your InputActivity
public class InputActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_input);
}
//Send data to HasilActivity.java
Intent intent = new Intent(this, HasilActivity.class);
// put your data here
intent.putExtra("value_one", editText.getText().toString().trim());
intent.putExtra("value_two", editText2.getText().toString().trim());
startActivity(intent)
}
and in your HasilActivity
public class HasilActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_hasil);
String value = getIntent().getStringExtra("value_one");
String value2 = getIntent().getStringExtra("value_two");
}
}
that is :)

App shutting down

So I want to implement a ProgressBar and set it on 100% but somehow it keeps crashing in the Emulator.
Heres the Code(MainActivity.java):
package com.example.schwarzerritter.remotec;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.ProgressBar;
public class MainScreen extends AppCompatActivity {
ProgressBar fuelBar;
public Button lDoor;
public void lDoorPageOpen() {
lDoor = (Button) findViewById(R.id.lDoor);//weist unseren Button lDoor in Java zu
lDoor.setOnClickListener(new View.OnClickListener() {//
#Override
public void onClick(View v) {
Intent lDoorPage = new Intent(MainScreen.this, lDoorPageOpen.class);//deklarieren eines intents
startActivity(lDoorPage);//starte intent lDoorPage
}
});
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_screen);
fuelBar.setProgress(100);
lDoorPageOpen();
fuelBar =(ProgressBar)findViewById(R.id.fuelB);
}
}
and this is the .xml file:

First Initialize Progressbar then use setProgress(100).
fuelBar =(ProgressBar)findViewById(R.id.fuelB);
lDoorPageOpen();
fuelBar.setProgress(100);
Check the order of your code, Progress bar must initialized before set progress.
