I'm trying to implement the Navigation Drawer Activity on my Dashboard Activity. In my application, I have created a Theme where the 'Toolbar/ActionBar' is removed and just put an ImageView for my burger menu on a custom layout and include it on my dashboard layout. What I wanted is that when this ImageView is clicked the sliding drawer will display.
What I tried to do is add an Navigation Drawer Activity by com.project.projectname -> New -> activity -> 'Navigation Drawer Activity' and automatically it adds NavigationActivity class , activity_navigation.xml
app_bar_navigation.xml, etc.
But I was wondering how can I open the drawer?
In my Dashboard Activity I added this
public class DashboardActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.dashboard);
View side_tab = findViewById(R.id.side_tab);
expanded_menu = (ImageView) side_tab.findViewById(R.id.expanded_menu);
expanded_menu.setOnClickListener(new View.OnClickListener(){
public void onClick(View v) {
// open drawer here
}
});
Also, in NavigationActivity it uses ActionBarDrawerToggle, I must not use this because I don't apply an ActionBar. But what alternative can I use?
Here is my NavigationActivity
public class NavigationActivity extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_navigation);
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);
}
#Override
public void onBackPressed() {
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
if (drawer.isDrawerOpen(GravityCompat.START)) {
drawer.closeDrawer(GravityCompat.START);
} else {
super.onBackPressed();
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.navigation, 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);
}
#SuppressWarnings("StatementWithEmptyBody")
#Override
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
Intent goToSreen;
if (id == R.id.nav_dashboard) {
goToSreen = new Intent(NavigationActivity.this, DashboardActivity.class);
startActivity(goToSreen);
} else if (id == R.id.nav_others) {
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
}
Thank you for your kind help.
Update
So in my Dashboard Activity I added the following
NavigationActivity navigationActivity;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.dashboard);
View side_tab = findViewById(R.id.side_tab);
expanded_menu = (ImageView) side_tab.findViewById(R.id.expanded_menu);
expanded_menu.setOnClickListener(new View.OnClickListener(){
public void onClick(View v) {
navigationActivity = new NavigationActivity() ;
navigationActivity.drawer.openDrawer(GravityCompat.START);
}
});
And in my Navigation Activity I add a global variable
public class NavigationActivity extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener {
DrawerLayout drawer;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_navigation);
drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
}
I have managed to call the drawer in my Dashboard Activity but the sliding menu still doesn't display when I clicked my burger menu. The app crashes and displays java.lang.NullPointerException: Attempt to invoke virtual method 'void android.support.v4.widget.DrawerLayout.openDrawer(int)' on a null object reference
Add this in your NavigationActivity
public class NavigationActivity extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener {
//Add this line
public static DrawerLayout drawer;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_navigation);
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();
.......
And next change this
expanded_menu.setOnClickListener(new View.OnClickListener(){
public void onClick(View v) {
// open drawer here
NavigationActivity. drawer.openDrawer(GravityCompat.START);
}
});
Try this hope it will solve your problrm.
Add the following code in NavigationActivity:
DrawerLayout mDrawerLayout; // Declare globally
In onCreate() :
mDrawerLayout = (DrawerLayout) findViewById(R.id.nav_drawer);
expanded_menu = (ImageView) side_tab.findViewById(R.id.expanded_menu);
expanded_menu.setOnClickListener(new View.OnClickListener(){
public void onClick(View v) {
// open drawer here
mDrawerLayout.openDrawer(Gravity.LEFT);
}
});
If the drawer is open, close it onBackPressed():
#Override
public void onBackPressed() {
if (mDrawerLayout.isDrawerOpen(Gravity.LEFT)) {
mDrawerLayout.closeDrawer(Gravity.LEFT);
return;
}
}
Hope this helps.
I extend my NavigationActivity to my DashboardActivity like below
public class DashboardActivity extends NavigationActivity {
side_tab = findViewById(R.id.side_tab);
expanded_menu = (ImageView) side_tab.findViewById(R.id.expanded_menu);
expanded_menu.setOnClickListener(new View.OnClickListener(){
public void onClick(View v) {
side_tab.setVisibility(View.INVISIBLE);
drawer.openDrawer(GravityCompat.START);
}
});
and then follow the said answered by #Hassan Usman and #tahsinRupam
after that I added the DrawerLayout in my dashboard.xml

I have this nav drawer which was working perfectly fine.
Refactoring my code I removed all onOptionsItemSelecteds in activities and made all activities inherit from a base activity which extends AppComplatActivity and implements all the necessary methods.
After this clicking on hamburger icon does not work any more even though I have syncstate() and every thing.
Any clues why this is not working?
One of the activities:
public class MainActivity extends BaseActivity implements SearchFilterFragment.OnFragmentInteractionListener {
NavigationView navigationView;
DrawerLayout drawerLayout;
private Tracker mTracker;
#Override
protected void onResume() {
super.onResume();
drawerLayout.openDrawer(GravityCompat.START);
}
#Override
protected void onPostResume() {
super.onPostResume();
mTracker.setScreenName("MainActivity" + "-----");
mTracker.send(new HitBuilders.ScreenViewBuilder().build());
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
getWindow().getDecorView().setLayoutDirection(View.LAYOUT_DIRECTION_RTL);
drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
drawerLayout.openDrawer(GravityCompat.START);
navigationView = (NavigationView) findViewById(R.id.navigation_view_primary);
navigationView.setNavigationItemSelectedListener(new NavigationDrawerListener(this));
setupToolbar();
Haftdong application = (Haftdong) getApplication();
mTracker = application.getDefaultTracker();
}
private void setupToolbar() {
// Show menu icon
final ActionBar actionBar = getSupportActionBar();
actionBar.setDisplayHomeAsUpEnabled(true);// will make the icon clickable and add the < at the left of the icon.
DrawerLayout mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
mDrawerLayout.setDrawerListener(mDrawerToggle);
mDrawerToggle.syncState();//for hamburger icon
}
#Override
public void onFragmentInteraction(Uri uri) {
}
}
BaseActivity:
public class BaseActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_base, 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);
}
}
You're using the four-parameter constructor for ActionBarDrawerToggle, which means you'll have to call the toggle's onOptionsItemSelected() method in MainActivity's onOptionsItemSelected() override in order to open/close the drawer.
For example:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if(mDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}
If you happen to be providing your own Toolbar – e.g., as the support ActionBar (though it's not necessary to set it as such) – then you can instead pass that Toolbar as the third argument in the ActionBarDrawerToggle constructor call. For example:
Toolbar toolbar = findViewById(R.id.toolbar);
ActionBarDrawerToggle mDrawerToggle = new ActionBarDrawerToggle(this, drawerLayout,
toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
The drawer opening/closing will then be handled by ActionBarDrawerToggle internally, and you won't need to call through to the toggle in onOptionsItemSelected().
The setDisplayHomeAsUpEnabled() call is also unnecessary for this setup, which is handy if you don't want to set the Toolbar as the ActionBar.
I'm developing a project on android and completely new to this. I had made a drawer menu with some of menu items. Now when i want to put another activity on click from menu items, the drawer closes automatically, it doesn't work. Here
private DrawerLayout mdrawerLayout;
private ActionBarDrawerToggle mdrawerToggle;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mdrawerLayout = (DrawerLayout) findViewById(R.id.drawer);
mdrawerToggle = new ActionBarDrawerToggle(this, mdrawerLayout, R.string.open, R.string.close);
mdrawerLayout.addDrawerListener(mdrawerToggle);
mdrawerToggle.syncState();
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (mdrawerToggle.onOptionsItemSelected(item)) {
return true;
}
int id = item.getItemId();
if(id == R.id.setup){
Intent csetup = new Intent(MainActivity.this, Subactivity.class);
startActivity(csetup);
return false;
}
return super.onOptionsItemSelected(item);
}
}
`
Try this:
Add below code in your onCreate method:
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.addDrawerListener(toggle);
toggle.syncState();
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
Implement lister in your mainactivity class:
public class MainActivity extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener
And after that in your onNavigationItemSelected method look like this:
#SuppressWarnings("StatementWithEmptyBody")
#Override
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
if (id == R.id.setup) {
//call new activity
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
Hope this may help you
This is because you are overriding the wrong method. You have to override onNavigationItemSelected() for drawer, instead of onOptionsItemSelected() which is for top-right settings menu. See the following code for reference:
#Override
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
if (id == R.id.setup) {
Intent csetup = new Intent(MainActivity.this, Subactivity.class);
startActivity(csetup);
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
First find the view for you NavigationView using findViewById method like below-NavigationView navView=(NavigationView)findViewById(R.id.navView)
then use this.
navView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
int id = item.getItemId();
if (id == R.id.setup) {
Intent csetup = new Intent(MainActivity.this, Subactivity.class);
startActivity(csetup);
}
return false;
}
});
then it will work.. onOptionsItemSelected(MenuItem item) is used to get the access to the MenuItems we have inflated on toolbar or on other layouts using onCreateOptionsMenu() method.
Android Error I'm a real noob when it comes to Android Studio, and I'm trying to make it so when I click a button in IntroActivity, it will direct me to the FeaturedActivity page, which contains a list and navigation drawer, if that's important. But when I click the first time in the emulator, the app stops, and when I go back and click it again, nothing happens. I have Java Code for both activities. Could someone help me please?
<activity

The question is a little vague on the details, but taking a shot in the dark, did you register FeaturedActivity in the app manifest?
Something like:
<activity
android:name=".FeaturedActivity"
android:label="#string/title_activity_featured"
android:theme="#style/AppTheme">
should be in your AndroidManifest.xml file.
You are probably getting a nice error message in logcat, so please look there :)
I think the crash cause is where you are casting FeaturedActivity to View.OnClickListener inside FeatureActivity#onCreate(). since it does not implement View.OnClickListener, you get ClassCastException and since you do not catch this exception, then your app crashes.
EDIT I meant this line:
public class FeaturedActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener {
...
#Override
protected void onCreate(Bundle savedInstanceState) {
...
myListView.setOnClickListener((View.OnClickListener) this); // this line
}
...
}
EDIT 2 You can fix it by implementing View.OnClickListener in FeatureActivity like this:
public class FeaturedActivity extends AppCompatActivity implements
NavigationView.OnNavigationItemSelectedListener, View.OnClickListener {
...
#Override
protected void onCreate(Bundle savedInstanceState) {
...
myListView.setOnClickListener(this); // cast is not needed anymore
}
#Override
protected void onClick(View v) {
// handle click
}
...
}
By the way, If you want to handle item click for ListView you should use AdapterView#setOnItemClickListener() instead so you get notified when one of the items in ListView is clicked
I got a problem that DrawerLayout does not close smoothly and it stops in the middle for a while, it totally closes after finish replacing fragment. In coding I close DrawerLayout before replacing fragment (productList class). In productList class, it calls asynctask to get all the product list from server meanwhile running progress bar. Ideally when user clicks menu, DrawerLayout will close at once and productList fragment will be loading all the product list. It seems to me DrawerLayout close event waits for productList's asynctask. Any suggestion greatly appreciated.

}
#Override
public void onClick(View v) {
//Log out onclick
if(v.getId() == R.id.nav_header_main_logout){

}
This probably happens beacuse the Navigation Drawer's animation and the creation of the Fragment happens at the same time.
You can solve it by starting your Fragment with a small delay-
handler.postDelayed(new Runnable() {
#Override
public void run() {
// replace fragment
int id = item.getItemId();
FragmentManager fragmentManager = getSupportFragmentManager();
if(Constants.DEBUG) {
Toast.makeText(mContext, " Menu Id " + String.valueOf(id), Toast.LENGTH_LONG).show();
}
fragmentManager.beginTransaction()
.replace(R.id.container,new productList())
.commit();
}
}, 300);
