I'm trying to build app with navigation drawer. What do I need is to be able of changing image dynamically on the head of navigation drawer from code by using glide. After putting this code I get the navigation header twice like on the picture. How to fix it?
nav_header_main.xml

MainActivity.java
NavigationView navigationView = null;
ImageView imgProfile = null;
String URL = "http://something.com/image.jpg";
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
navigationView = (NavigationView) findViewById(R.id.nav_view);
View hView = navigationView.inflateHeaderView(R.layout.nav_header_main);
imgProfile = (ImageView)hView.findViewById(R.id.imageView);
Glide.with(getApplicationContext()).load(URL).into(imgProfile);
navigationView.setNavigationItemSelectedListener(this);
}
remove this
app:headerLayout="#layout/nav_header_main"
from your Navigationview in Xml

I have tried to implement navigation drawer in my app with androidx library. So far, the app show hamburger icon on top left corner, but to access the drawer I have to swipe right. If I clicked the icon it will go to previous activity instead. Is it because this activity is not the main activity? How can I fix this? Thank you in advance.
Here is my activity
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_list);
DrawerLayout drawerLayout = findViewById(R.id.drawerLayout);
ActionBarDrawerToggle t = new ActionBarDrawerToggle(this, drawerLayout,R.string.Open, R.string.Close);
drawerLayout.addDrawerListener(t);
t.syncState();
NavigationView nv = findViewById(R.id.navigationView);
nv.setNavigationItemSelectedListener(item -> {
int id = item.getItemId();
switch(id)
{
case R.id.action_open_list:
break;
case R.id.action_closed_list:
Intent closedListIntent = new Intent(this, ClosedListActivity.class);
startActivity(closedListIntent);
break;
default:
return true;
}
return true;
});
}
my layout
<?xml version="1.0" encoding="utf-8"?>

You have to include your Nav. Drawer menu items like this , Check the below xml code as references :
Here included as app:menu="#menu/nav_drawer_items"
You can take the reference of this question with solution : Align custom view to left of navigation drawer

I am using a RecyclerView in a Fragment. I want the fragment to match the parent in width and height. But this is my output.
There is that space being left around the fragment. I want to eliminate that. I have tried everything, i.e, making the third parameter false, using parent container , changing the LayoutParams to match_parent but nothing has worked.
My code:-

I have created a navigation drawer,When user click on hamburger icon it opens the drawer. I need to add a close button in drawer. This is what i need to implement.

ActionBarDrawerToggle will fix your problem:
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerToggle = new ActionBarDrawerToggle(
this, /* host Activity */
mDrawerLayout, /* DrawerLayout object */
R.drawable.ic_drawer, /* nav drawer icon to replace 'Up' caret */
R.string.drawer_open, /* "open drawer" description */
R.string.drawer_close /* "close drawer" description */
) {
/** Called when a drawer has settled in a completely closed state. */
public void onDrawerClosed(View view) {
super.onDrawerClosed(view);
getActionBar().setTitle(mTitle);
}
/** Called when a drawer has settled in a completely open state. */
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
getActionBar().setTitle(mDrawerTitle);
}
};
// Set the drawer toggle as the DrawerListener
mDrawerLayout.setDrawerListener(mDrawerToggle);
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);

drawer.closeDrawer(Gravity.LEFT);
}
});
I believe you want to know how to add the "x" button. Well, Do you see the line below in your NavigationView :
app:headerLayout="#layout/navigation_drawer_header"
This is the header layout of your drawer. Open this layout and put your ImageView in it. As simple as that.
Add a click listener to the imageview of the X icon.
imageView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Drawer.closeDrawer(Gravity.LEFT);
}
});
To add the icon you want to do a sort of custom view

EDIT 1 ======================================================
Here is the OnCreate of MainActivity
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.setDrawerListener(toggle);
toggle.syncState();
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
dbHelper = new DBHelper(this);
textViewGold = (TextView) findViewById(R.id.textViewGold);
taskListFragment = (TaskListFragment) getSupportFragmentManager().findFragmentByTag("taskList");
inventoryFragment = (InventoryFragment) getSupportFragmentManager().findFragmentByTag("inventory");
loadGuiStuff();
if (taskListFragment == null)
{
taskListFragment = new TaskListFragment();
transaction = getSupportFragmentManager().beginTransaction();
transaction.add(R.id.fragmentParentViewGroup, taskListFragment);
transaction.commit();
}
}
Fixed it, needed to clean the project ......
