It's apparently a question that has been asked multiple times, but only has solutions on a case-by-case basis.I am making an aap with toolbar and when i go to second activity i want the toolbar to display icon as well as settings menu but unfortunately toolbar is appearing but icons are not showing also android monitor shows null pointer exception on these lines of code
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);

There may be few reasons of NullPointException, try to:
You are probably using a Theme that doesn't support ActionBar.
Trying using this theme:
android:theme="#android:style/Theme.Holo.Light".
try to catch:
if (getSupportActionBar() != null)
{
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
}
Or, try to change the id of app_bar in aap.java
findViewById method returning null.
Add id attribute to your toolbar
android:id="#+id/aap_bar
You are also using wrong namespace aap
Use app
xmlns:app="http://schemas.android.com/apk/res-auto"

Since a few days ago I decided to program for Android and buy a book about that. There are several examples and I have achieved them satisfactorily but at the moment of programming the navigation drawer and running it on my cell phone it appears that it closed unfortunately. In the console of Android Studio does not appear any error and I was reviewing codes, example, etc and I have not been able to solve the problem.

the main activity is where the main view will be shown and it will be linked to app_bar_main_xml where the other components are located that have no relation to the navigation drawer and work correctly and therefore I will not put the code.

This question already has answers here:
The application icon does not show on action bar
(6 answers)
Closed 5 years ago.
In my Android application, I'm trying to use setlogo(), ActionBar and android:icon but they don't work as expected: Output shows absolutely no icon and I'm really confusing about it. I need your help.
My code:
import android.content.Intent;
import android.support.v7.app.ActionBar;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;
import android.support.v7.widget.Toolbar;
import android.view.Menu;
import android.view.MenuItem;
public class MainActivity extends AppCompatActivity {
RecyclerView recyclerView;
Toolbar toolbar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
getSupportActionBar().setHomeButtonEnabled(true);
getSupportActionBar().setDisplayShowTitleEnabled(false);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setIcon(R.mipmap.ic_launcher_round);
//recyclerview
recyclerView= (RecyclerView) findViewById(R.id.recycle_main);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
recyclerView.setHasFixedSize(true);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_mainactivity,menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch(item.getItemId()){
case R.id.menu_add_contects:
startActivity(new Intent(MainActivity.this,AddContects.class));
return true;
default:
return super.onOptionsItemSelected(item);
}
}
}
To set an icon in your ActionBar you need to call
setHomeAsUpIndicator() instead of setIcon()
Like this:
final ActionBar actionBar = getSupportActionBar();
if (actionBar != null) {
actionBar.setHomeAsUpIndicator(R.drawable.ic_arrow_back);
actionBar.setDisplayHomeAsUpEnabled(true);
}
You can set any image in toolbar using the following code.
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/AppTheme.PopupOverlay" >
<RelativeLayout
android:layoutDirection="ltr"
android:gravity="center_vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/camera"
android:src="#drawable/camera"
android:layout_toStartOf="#+id/search"
android:paddingStart="#dimen/margin_10"
android:paddingEnd="#dimen/margin_10"
android:layout_width="wrap_content"
android:layout_height="match_parent" />
<ImageView
android:id="#+id/search"
android:layout_alignParentEnd="true"
android:src="#drawable/search"
android:paddingStart="#dimen/margin_10"
android:paddingEnd="#dimen/margin_10"
android:layout_marginEnd="#dimen/margin_6"
android:layout_width="wrap_content"
android:layout_height="match_parent" />
</RelativeLayout>
</android.support.v7.widget.Toolbar>
I'm a complete noob to programming, so thank you for your patience.
In my main activity I have a random quote showing up, then I created a Navigation Drawer (with the help of a youtube tutorial of course). How do I make these "items" react when I click on them? For example, one of them is a glossary, so I will need to write a lot. Should I create an Activity or a Fragment (what's the difference anyway)? And how do I make a click on top of "Glossary" open that View?
Thank you once more :)
Edit: (Here are my relevant codes and layouts)

getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}
#Override

if (mToggle.onOptionsItemSelected(item)){
return true;
}
return super.onOptionsItemSelected(item);
}
First, you need to set onClickListener on your Navigation View like the following :-
yourNavigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
switch(menuItem.getItemId()) {
// Here in each case statement you need to pass the id of the menu items and then call startActivity(new Intent()) in each case statement.
case R.id.your_item:
startActivity(new Intent(currentClass.this, nextActivity.class));
break;
}
i try to add icon menu in toolbar. but my icon not showing. here my code. only show blank header. can someone help me...

}
this is my custom toolbar layout
<?xml version="1.0" encoding="utf-8"?>

</LinearLayout>
and my menu icon
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"

<item

android:icon="#drawable/ic_back_filled"
app:showAsAction="always"
android:title="back"/>
</menu>
can anyone tell me whats wrong with my code?
Try this:
public class AddProjectFragment extends Fragment {
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_add_project, container,false);
Toolbar myToolbar = (Toolbar) rootView.findViewById(R.id.my_toolbar);
((AppCompatActivity)getActivity()).setSupportActionBar(myToolbar);
return rootView;
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.header, menu);
super.onCreateOptionsMenu(menu, inflater);
}
}
Actually to include a action bar in fragment.Remove the on menu function and put relative layout inside your toolbar in layout.Inside this relative layout adda imageview with he appropriate position that you want.You are getting a blank space because of the empty toolbar area.Adding view inside it will show the image you want to show.
I want something like the swiping pages in the Google Play Store.

Tried multiple things found on the internet, changing xml etc doesn't do the trick.
In xml you have to put below Toolbar code for the action bar:
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/colorPrimary"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light">
</android.support.v7.widget.Toolbar>
In java file:
a. extend class with AppCompatActivity
b. you have to put the below code for set the title:
Toolbar mActionBarToolbar = (Toolbar) findViewById(R.id.toolbar);
mActionBarToolbar.setTitle("Pluff");
