OnClick item in NavigationDrawer in Android Studio

I know this is common to ask but I really confused about how can I apply onClickListener to my navigationDrawer items, I have two items which is edit profile and Logout I just want to Toast or print if one of them is selected, Is there anyone can help me with this, I've already search on the internet , yet there's no OnClickListener I've found, need help
I think there's missing on my MainActivity which is the onCreate()
OnCreate() MainActivity
setContentView(R.layout.dashboard_main);
DrawerLayout drawerLayout = findViewById(R.id.drawerlayout);
NavigationView navigationView = (NavigationView) findViewById(R.id.navigationview);

Updated I tried the code below but when I click the items it will automatically hide back the sidebar and there are no Toast pops
navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(MenuItem item) {
if (item.getItemId() == R.id.editProfile)
{
Toast.makeText(getApplicationContext(),"profile",Toast.LENGTH_SHORT).show();
}
else if (item.getItemId() == R.id.logout_menu)
{
Toast.makeText(getApplicationContext(),"logout",Toast.LENGTH_SHORT).show();
}
return false;
}
});

First you need to implement NavigationView.OnNavigationItemSelectedListener interface on your Activity.
then on your onCreate() method type
navigationView.setNavigationItemSelectedListener(this); after this override the method onNavigationItemSelected.
here you can use this sample code.
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
if (item.getItemId() == R.id.editProfile)
{
//edit your profile
}
else if (item.getItemId() == R.id.logout)
{
//log out
}
return false;
}

How to load a picture in the ImageView of a collapsing toolbar?

I just created an Activity to show some product informations and this Activity has a Collapsing Toolbar. I wanted to load an image by Picasso as soon as the Activity opens.
Here is the current code :
public class ProductActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_product);
Product p = (Product) getIntent().getExtras().getSerializable("product");
setSupportActionBar((Toolbar) findViewById(R.id.toolbar));
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowHomeEnabled(true);
getSupportActionBar().setTitle(p.getProductName());
TextView name = (TextView) findViewById(R.id.product_name);
TextView type = (TextView) findViewById(R.id.product_type);
TextView description = (TextView) findViewById(R.id.product_description);
TextView ingredients = (TextView) findViewById(R.id.product_ingredients);
TextView price = (TextView) findViewById(R.id.product_price);
ImageView thumbnail = (ImageView) findViewById(R.id.product_thumbnail);
name.setText(p.getProductName());
type.setText(p.getProductType().getDisplayName());
description.setText(p.getProductDescription());
ingredients.setText("Non disponible");
price.setText(p.getProductPrice().length>1 ? "À partir de "+p.getProductPrice()[0].toString()+"€" : p.getProductPrice()[0].toString()+"€");
Picasso.with(this).load(p.getProductThumbnailURL()).fit().into(thumbnail);
Picasso.with(this).load(p.getProductThumbnailURL()).fit().into((ImageView)findViewById(R.id.test), new Callback() {
#Override
public void onSuccess() {
}
#Override
public void onError() {
Toast.makeText(ProductActivity.this, "Impossible de charger l'image !", Toast.LENGTH_SHORT).show();
}
});
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if(item.getItemId()==android.R.id.home)finish();
return super.onOptionsItemSelected(item);
}
}
And here is a screen of the Activity (don't take care of the design xD)

Instead of wrap_content for your product_thumbnail ImageView height use match_parent or a fixed size.
Hope this helps

Floating action button menu dont scroll with header

I am currently coding a small app, and I trying to integrate the "material design" of Google.
I use in my app to github's floating Action menu button library and I have some worries.
Unlike the single button, the menu generates a larger view. I put my menu down the fab header. But the code does not seem good.
I wish to bring up the menu fab down my header properly (I use the CollapsingToolbarLayout). And the menu follows the scroll. But i'm stuck here.
My question is how to put the menu fab between my header and my cardviews, and how to scroll the fab menu with my collapsing toolbar.
Thank you in advance.

Change you layout_anchor to "appbarlayout" instead of "image"

And here my Java code:

getMenuInflater().inflate(R.menu.menu_principal, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
public void ajuda(View v) {
Intent intent = new Intent(this, Ajuda.class);
startActivity(intent);
}
public void onClickcrea (View view){
EditText textContra1 =(EditText) findViewById(R.id.editTextContra);
contrasenya1 = textContra1.getText().toString();
EditText textContra2 = (EditText) findViewById(R.id.editTextContraR);
contrasenya2 = textContra2.getText().toString();
Toast missatge = Toast.makeText(getApplicationContext(), "Les contrasenyes han de coincidir!", Toast.LENGTH_SHORT);
missatge.show();
}
}

Personally I would suggest using a onClickListener instead of the XML attribute.

The method defined in the android:onClick could not be found in the activity that the view was inflated in.
The most common mistakes for this error are method name typo and wrong layout inflation.
As stated in other comments you should rather use onClickListeners.

DetailsFragment
public class DetailsFragment extends Fragment {

// Required empty public constructor

View view = inflater.inflate(R.layout.fragment_details, container, false);
return view;
}
}
Please help..

There is nothing in your activity layout with android:id="#+id/LinearContainer, and so FragmentManager does not have anywhere to place your DetailsFragment.
