How to make the top bar?

Why when I write this code the application crashing?
Toolbar mToolbar = findViewById(R.id.scroll_top_bar);
setSupportActionBar(mToolbar);
This is the xml code
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".DisplayInformations">
<com.google.android.material.appbar.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:liftOnScroll="true">
<com.google.android.material.appbar.CollapsingToolbarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="#drawable/ic_launcher_background" />
<androidx.appcompat.widget.Toolbar
android:id="#+id/scroll_top_bar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize" />
</com.google.android.material.appbar.CollapsingToolbarLayout>
</com.google.android.material.appbar.AppBarLayout>
</LinearLayout>
This is the java code
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_display_informations);
Toolbar mToolbar = findViewById(R.id.scroll_top_bar);
setSupportActionBar(mToolbar);
}
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
getMenuInflater().inflate(R.menu.menu_display_informations,menu);
return true;
}

I am having toolbar in MainActivity. This is my fragment i want to set title, image and back button inside the toolbar. Here i am using bottom navigation to change the fragments. Each and every fragment i want to set different title and image. I have to set title as center of the toolbar and back button as right corner of the toolbar.

In your MainActivity add these lines in OnCreate() method
if (getSupportActionBar() != null) {
getSupportActionBar().setTitle("My Activity Title");
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}
To use Back arrow you can write this code outside onCreate()
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (item.getItemId() == android.R.id.home) {
Toast.makeText(this, "Back button pressed", Toast.LENGTH_SHORT).show();
return true;
}
return super.onOptionsItemSelected(item);
}
In you fragment you can change title of Toolbar
getActivity().setTitle("My fragment Title");

You can Create custom Toolbar with ImageView and TextView with your arrow .
include_tool_bar.xml
<com.mastercard.wallet.ui.widget.CustomTextView
android:id="#+id/toolbar_title"
style="#style/Toolbar.TitleText"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center_vertical|left"
android:textSize="#dimen/px_48"
app:fontName="InterStateLight"
customviews:fontName="InterStateLight" />
<ImageView
android:id="#+id/toolbar_logo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:contentDescription="#string/adaCitiPayLogoText"
android:src="#drawable/ab_logo"
android:visibility="gone" />
And Add Toolbar
Toolbar toolbar = (Toolbar) appCompatActivity.findViewById(R.id.toolbar);
ImageView logo = (ImageView) toolbar.findViewById(R.id.toolbar_logo);
CustomTextView textView = (CustomTextView) toolbar.findViewById(R.id.toolbar_title);
logo.setVisibility(View.VISIBLE);
logo.setImageResource(logoResourceId);
textView.setVisibility(View.GONE);
appCompatActivity.setSupportActionBar(toolbar);
appCompatActivity.getSupportActionBar().setDisplayShowTitleEnabled(false);

title of the toolbar can be changed from fragment calling this in onActivityCreated
#Override
public void onActivityCreated(#Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
((MainActivity) getActivity()).getSupportActionBar().setTitle(getString(R.string.menu_about_us));
((MainActivity) getActivity()).getSupportActionBar().setDisplayHomeAsUpEnabled(true);
((MainActivity) getActivity()).getSupportActionBar().setDisplayShowHomeEnabled(true);
}
in your activity make sure to add a toolbar like this.
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#color/colorPrimary"
app:popupTheme="#style/AppTheme.PopupOverlay"/>
and set it in your activity
setSupportActionBar(findViewById(R.id.toolbar));
and for the back press just add a listener and do the needful.
toolbar.setNavigationIcon(getResources().getDrawable(R.drawable.ic_action_back));
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// pop up fragment or take another action
}
});

ItemDetailsActivity. java (This is the .java file of this image where i am unable to see the shopping cart icon, so i am unable to see how many items add in the cart)
public class ItemDetailsActivity extends AppCompatActivity {

Java Android : onItemLongClick for listView doesn't respond

I'm developing an Android application.
I want to display a list of contacts (using listview) and I want to add 2 alerts dialogs: one by onItemClickListener and the other by onItemLongClickListener.
But the onItemLongClickListener is never called, just the onItemClickListener.
I already did it for another application, but here it doesn't work and I don't find why :/
My code:
public class ContactActivity extends AppCompatActivity {
private ListView listView;
private ContactAdapter adapter; //my adapter
private ArrayList<Contact> contacts; //my list of contacts
//...
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_contact);
//here i init my "listView" and "contacts"
adapter = new ContactAdapter(this, contacts);
listView.setAdapter(adapter);
adapter.notifyDataSetChanged();
listView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
#Override
public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
Log.e("longClick", "ok");
return true;
}
});
listView.setOnItemClickListener(new AdapterView.OnItemClickListener(){
#Override
public void onItemClick(AdapterView<?> a, View v, final int position, long id) {
//here i display a Dialog
}
});
//some code
So, when I "simple click" on an item of the list, the dialog appears (ok).
But when I "long click" on an item of the list, the dialog appears and i don't see the Log...
(The item that i use for my ListView got just 2 EditText)
PS: the XML where my listView is shown

SOLUTION
I had a onSwipeRight() on my listener, it blocked the onItemLongClickListener
here is the code that was blocking the listener
listView.setOnTouchListener(new OnSwipeTouchListener(getApplicationContext()) {
public void onSwipeRight(){
//some code
}
});
Big thanks to ddb for his time :)

why are you passing a new AdapterView.OnItemLongClickListener?
just do like this below instead
listView.setOnItemLongClickListener(new OnItemLongClickListener() {
#Override
public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
Log.e("longClick", "ok");
return true;
}
});

Do not set listView.setLongClickable(true);, listView.setClickable(true); in your java.
Neither
android:longClickable="true"
android:clickable="true"
Inside your xml

The application may be doing too much work on its main thread. Even using AsyncTask

I am creating a android application.
In my app I have one listView and one gridView and when I set the addapter of those view I get the The application may be doing too much work on its main thread
I have try to put those setadapter on a AsyncTask but nothing change.. I do not understand.
My Activity :
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
showToolbarTitle(false);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
toolbarTitle.setText("PARALLAX + FADING IMAGEVIEW");
toolbarTitle.setVisibility(View.INVISIBLE);
scrollview.setScrollViewCallbacks(this);
listView = (ListView) findViewById(R.id.listview);
gridView = (GridView) findViewById(R.id.gridView);
new LongOperation().execute(); //I call the AsyncTask
gridView.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_MOVE) {
return true;
}
return false;
}
});
}
private class LongOperation extends AsyncTask<String, Void, String> {
#Override
protected String doInBackground(String... params) {
CustomList adapter = new
CustomList(ParallaxLikeIoshedActivity.this, test, imageId, false);
// listView.setAdapter(adapter); // If I do this I will get the error
CustomList adapterGrid = new
CustomList(ParallaxLikeIoshedActivity.this, test, imageId, true);
// gridView.setAdapter(adapterGrid); // If I do this I will get the error
return "Executed";
}
#Override
protected void onPostExecute(String result) {
}
#Override
protected void onPreExecute() {}
#Override
protected void onProgressUpdate(Void... values) {}
}
This is the layout of the Activity :
