I'm working on an app but I have some troubles with drawer layout. I always getting the error message like I mentioned in the title but I have no such Gravity with LEFT value. All I have are gravities with END values and that's all.
Here is my Java code:
public class HomeActivity extends AppCompatActivity {
private ActionBarDrawerToggle toggle;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
Toolbar mainToolBar =findViewById(R.id.main_page_toolbar);
DrawerLayout mainDrawerLayout = findViewById(R.id.main_page_drawer_layout);
NavigationView mainNavigationView = findViewById(R.id.main_page_navigation_view);
setSupportActionBar(mainToolBar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowTitleEnabled(false);
getSupportActionBar().setHomeButtonEnabled(true);
toggle = new ActionBarDrawerToggle(this,mainDrawerLayout,mainToolBar,R.string.openDrawer,R.string.closeDrawer);
mainDrawerLayout.addDrawerListener(toggle);
toggle.syncState();
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
toggle.onConfigurationChanged(newConfig);
}
}
And here is my XML code:
<?xml version="1.0" encoding="utf-8"?>
<androidx.drawerlayout.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

app:menu="#menu/home_side_menu"
android:layoutDirection="rtl"

You need to handle navigation click on Toolbar like below:
mainToolBar.setNavigationOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (mainDrawerLayout.isDrawerOpen(GravityCompat.END))
mainDrawerLayout.closeDrawer(GravityCompat.END);
else
mainDrawerLayout.openDrawer(GravityCompat.END);
}
});
Also don't forgot to close drawer whenever needed like below:
mainDrawerLayout.closeDrawer(GravityCompat.END)
I have an app that displays the default activity as:
When clicked the hamburger icon opens left main navigation drawer as:
And when clicked the FILTER button opens another drawer from the right as:
I know how the left navigation drawer is displayed (all java codes and layouts)
What is the code for displaying the drawer that is opening from the right ?
and also i wanna know, how the on click listener is set up even if the FILTER button is outside the toolbar ?
Can anyone help?
Just change the value of tools:openDrawer to end (i.e tools:openDrawer="end"), also add android:layout_gravity="end" in <android.support.design.widget.NavigationView>. Here's the solution.

toggle.syncState();
//Add this piece of code
toolbar.setNavigationOnClickListener(new View.OnClickListener() {

}
Check out this -http://updateunlimited.blogspot.in/2015/12/double-sided-nav-drawers.html
it will take less time
also check how it open from right -https://stackoverflow.com/a/19358114/4741746 and https://stackoverflow.com/a/32155976/4741746 and https://stackoverflow.com/a/17156831/4741746
Best of luck
My navigation drawer are showing icon in a filter not real color
how t remove this filter
i am new please help me step by step.
Thank you!
Screenshot:
This issue is duplicated.
But I add answer for explanation.
Your layout file is like this:
(activity_main.xml)
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- The main content view -->
...
<android.support.design.widget.NavigationView
android:id="#+id/navigation_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:menu="#menu/navigation_item"/>
</android.support.v4.widget.DrawerLayout>
Your Activity is like this: (MainActivity.java)
Call navigationView.setItemIconTintList.
public class MainActivity extends AppCompatActivity {
...
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
...
NavigationView navigationView = (NavigationView) findViewById(R.id.navigation_view);
navigationView.setItemIconTintList(null);
...
}
...
}
EDIT: So the menu exists but I can only get to it by sliding the menu out, the button on the top left corner doesn't toggle the drawer open.
I'm trying to implement a nav menu but instead of a hamburger button showing that opens my menu, I'm left with a non-functioning back button. I'm assuming it's a little different than the Nav Button tutorial Google has due to using a toolbar as my action bar.
MainActivity.java:
private CharSequence mTitle;
private FragmentTabHost mTabHost;
private Toolbar toolbar;
private ListView mDrawerList;
private DrawerLayout mDrawerLayout;
FrameLayout frameLayout;

String TITLES[];
int ICONS[] = {R.drawable.drawer_back, R.drawable.drawer_settings,R.drawable.drawer_notifications, R.drawable.drawer_feedback};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TITLES = getResources().getStringArray(R.array.menu_array);
mTitle = getTitle();
toolbar = (Toolbar) findViewById(R.id.tool_bar); // Attaching the layout to the toolbar object
frameLayout = (FrameLayout) findViewById(R.id.frame_layout);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList = (ListView) findViewById(R.id.left_drawer);
mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);
mDrawerList.setAdapter(new ArrayAdapter<>(this,
R.layout.item_row, TITLES));
mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
mDrawerToggle = new ActionBarDrawerToggle(this,Drawer,R.string.openDrawer,R.string.closeDrawer){
public void onDrawerClosed(View view) {
getSupportActionBar().setTitle(mTitle);
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()

First, there's two DrawerLayouts declared, one called Drawer and one called mDrawerLayout. I'm going to use mDrawerLayout.
In the Drawer Toggle constructor, you can associate the toggle with the DrawerLayout and the Toolbar by declaring it with mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, toolbar, R.string.openDrawer, R.string.closeDrawer){
// rest of code
Then add another couple of lines
If you want the icon to change between a hamburger and an arrow when the drawer opens and closes use this listener:
mDrawerLayout.setDrawerListener(mDrawerToggle);
call syncState to put the button and drawer into the same state(open or closed):
mDrawerToggle.syncState();
You can achieve proper "back" navigation by handling the click events of the menu items. The one you're talking about in Android is referred as the Up button which is known as the home menu item. Add this code to your Activity and you'll be able to go back from the current Activity to the previous one:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (item.getItemId() == android.R.id.home) {
finish();
return true;
}
return super.onOptionsItemSelected(item);
}
Now there are way better ways to handle the UP navigation than this. This approach simply kills the current Activity you see which will end up behaving like a back navigation as you'd like to call it.
Please refer to this section from the Android documentation to understand what's the difference between
Back:
and Up:
Once you understand the difference, you can check out this section to understand how the proper Up navigation should be handled.
Cheers!
First of all I know this question appeared here before but after trying a lot I still didn't succeed.
I working on the example from
Android Developers site.
I'm trying to set the menu to be opened from right to left instead of how its implementing in the example (from left to right). In addition I want to move the open menu button to the right side of the action bar. I also red some answers here, for example in this answer.
I try to change the gravity of the views and the layouts but I get the error:
no drawer view found with absolute gravity LEFT
Can you please help me to figure out what is the problem in my code and what should I change in order to set the menu to be opened from the right, and to move the action bar button to the right side?
the xml code is here:
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_gravity="right"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<FrameLayout
android:id="#+id/content_frame"
android:layoutDirection="rtl"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
<ListView android:id="#+id/left_drawer"
android:layout_width="200dp"
android:layout_height="match_parent"
android:layout_gravity="right"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="10dp"
android:background="#111"/>
</android.support.v4.widget.DrawerLayout>
In your main layout set your ListView gravity to right:
android:layout_gravity="right"
Also in your code :
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
R.drawable.ic_drawer, R.string.drawer_open,
R.string.drawer_close) {
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (item != null && item.getItemId() == android.R.id.home) {
if (mDrawerLayout.isDrawerOpen(Gravity.RIGHT)) {
mDrawerLayout.closeDrawer(Gravity.RIGHT);
}
else {
mDrawerLayout.openDrawer(Gravity.RIGHT);
}
}
return false;
}
};
hope it works :)
Add this code to manifest:
<application android:supportsRtl="true">
and then write this code on Oncreate:
getWindow().getDecorView().setLayoutDirection(View.LAYOUT_DIRECTION_RTL);
It works for me. ;)
SOLUTION
your_layout.xml:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
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:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:openDrawer="end">
<include layout="#layout/app_bar_root"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<android.support.design.widget.NavigationView
android:id="#+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="end"
android:fitsSystemWindows="true"
app:itemTextColor="#color/black"
app:menu="#menu/activity_root_drawer" />
</android.support.v4.widget.DrawerLayout>
YourActivity.java:
#Override
protected void onCreate(Bundle savedInstanceState) {
//...
toolbar = (Toolbar) findViewById(R.id.toolbar);
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();
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (drawer.isDrawerOpen(Gravity.RIGHT)) {
drawer.closeDrawer(Gravity.RIGHT);
} else {
drawer.openDrawer(Gravity.RIGHT);
}
}
});
//...
}
This answer is useful to set the navigation be open from right to left, but it has no solution to set its icon to be right side. This code can fix it. If you give it the drawer as its first param and ViewCompat.LAYOUT_DIRECTION_RTL as its second param, the entier layout will be set to RTL. It is a quick and simple solution, but I don't think it can be a correct solution for who that want to only set the menu to be opened from right to left and set its icon to be on right side. (Although, it's depended to your purpose.) However, I suggest giving the toolbar instead of the drawer. In this way just the toolbar has become RTL. So I think the combination of these 2 answers can exactly do what you want.
According to these descriptions, your code should be like this:
(Add these lines to onCreate method)
final DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout); // Set it final to fix the error that will be mention below.
ViewCompat.setLayoutDirection(toolbar, ViewCompat.LAYOUT_DIRECTION_RTL);
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (drawer.isDrawerOpen(Gravity.RIGHT))
drawer.closeDrawer(Gravity.RIGHT);
else
drawer.openDrawer(Gravity.RIGHT);
}
});
Notice that you should make drawer final, otherwise you will get this error:
Variable 'drawer' is accessed from within inner class, needs to be
declared final
And don't forget to use end instead of start in onNavigationItemSelected method:
drawer.closeDrawer(GravityCompat.END);
and in your activity_main.xml
<android.support.v4.widget.DrawerLayout
android:id="#+id/drawer_layout"
tools:openDrawer="end">
<android.support.design.widget.NavigationView
android:id="#+id/nav_view"
android:layout_gravity="end"/>
</android.support.v4.widget.DrawerLayout>
Here is the documentation on the drawer and it appears that you can configure it to pull out from the left or right.
Drawer positioning and layout is controlled using the android:layout_gravity attribute on child views corresponding to which side of the view you want the drawer to emerge from: left or right. (Or start/end on platform versions that support layout direction.)
http://developer.android.com/reference/android/support/v4/widget/DrawerLayout.html
Take a look at this: slide ExpandableListView at DrawerLayout form right to left
I assume you have the ActionBarDrawerToggle implemented, the trick is to override the onOptionsItemSelected(MenuItem item) method inside the ActionBarDrawerToggle object with this:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (item != null && item.getItemId() == android.R.id.home) {
if (mDrawer.isDrawerOpen(Gravity.RIGHT)) {
mDrawer.closeDrawer(Gravity.RIGHT);
} else {
mDrawer.openDrawer(Gravity.RIGHT);
}
return true;
}
return false;
}
make sure and call this from onOptionsItemSelected(MenuItem item) in the Activity:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if(mDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}
This will allow you to use the the home button functionality. To move the button to the right side of the action bar you will have to implement a custom action item, and maybe some other stuff to get it to work like you want.
the main issue with the following error:
no drawer view found with absolute gravity LEFT
is that, you defined the
android:layout_gravity="right"
for list-view in right, but try to open the drawer from left, by calling this function:
mDrawerToggle.syncState();
and clicking on hamburger icon!
just comment the above function and try to handle open/close of menu like #Rudi said!
I have solved this problem by changing the gravity of the navigationview
android:layout_gravity
to end instead of start
<android.support.design.widget.NavigationView
android:id="#+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="end"
android:fitsSystemWindows="true"
app:headerLayout="#layout/nav_header"
app:menu="#menu/activity_drawer" />
It worked for me.
You should firstly put this code in your AppManifest.xml in the application tag:
android:supportsRtl="true"
then in your activity_main.xml file, put this piece of code:
android:layout_direction="rtl"
I did following modification to the Navigation Drawer Activity example in Android Studio. With support libraries 25.3.1.
MainActivity.java:
private DrawerLayout mDrawerLayout;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
ActionBar actionBar = getSupportActionBar();
if (actionBar != null) {
actionBar.setDisplayHomeAsUpEnabled(true);
}
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
}
#Override
public void onBackPressed() {
if (mDrawerLayout.isDrawerOpen(GravityCompat.END)) {
mDrawerLayout.closeDrawer(GravityCompat.END);
} else {
super.onBackPressed();
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int itemId = item.getItemId();
switch (itemId) {
case android.R.id.home:
finish();
return true;
case R.id.action_right_drawer:
if (mDrawerLayout.isDrawerOpen(GravityCompat.END)) {
mDrawerLayout.closeDrawer(GravityCompat.END);
} else {
mDrawerLayout.openDrawer(GravityCompat.END);
}
return true;
default:
return super.onOptionsItemSelected(item);
}
}
#SuppressWarnings("StatementWithEmptyBody")
#Override
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
mDrawerLayout.closeDrawer(GravityCompat.END);
return true;
}
main.xml (download ic_menu_white_24px from https://material.io/icons/):
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item android:id="#+id/action_right_drawer"
android:title="Drawer menu"
android:icon="#drawable/ic_menu_white_24px"
android:orderInCategory="100"
app:showAsAction="always" />
</menu>
In activity_main.xml change
android:layout_gravity="start"
to
android:layout_gravity="end"
Making it open from rtl isn't good for user experience, to make it responsive to the user locale I just added the following line to my DrawerLayout parameters:
android:layoutDirection="locale"
Added it to my AppBarLayout to make the hamburger layout match the drawer opening direction too.

In your layout file inside NavigationView set this attribute android:layout_gravity="end" and set tools:openDrawer="end" in the DrawerLayout

app:menu="#menu/drawer_actions" />
</androidx.drawerlayout.widget.DrawerLayout>
Output
I know this is an old question, but I've been struggling with this problem for a few days now and finally achived the solution.
If you want to use the default new project "Navigation Drawer Activity" to work with a drawer from right to left:
Create a custom DrawerLayout class:
public class CustomDrawerLayout extends DrawerLayout {
public CustomDrawerLayout(#NonNull Context context) {
super(context);
}
public CustomDrawerLayout(#NonNull Context context, #Nullable AttributeSet attrs) {
super(context, attrs);
}
public CustomDrawerLayout(#NonNull Context context, #Nullable AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
#Override
public void open() {
openDrawer(GravityCompat.END);
}
#Override
public void close() {
closeDrawer(GravityCompat.END);
}
#Override
public boolean isOpen() {
return isDrawerOpen(GravityCompat.END);
}
}
On activity_main.xml:
set DrawerLayout tools:openDrawer="end"
set NavigationView android:layout_gravity="end"
change tag view from androidx.drawerlayout.widget.DrawerLayout to your CustomDrawerLayout com.example.CustomDrawerLayout
If you create new menu options, it is important that the id of the item in menu/activity_main_drawer.xml is the same as the id of the fragment in navigation/mobile_navigation.xml.
Summarising multiple answers into one which worked for me.
Following were my requirements
1. Align navigation drawer hamburger icon to write
2. Start the navigation drawer from right to left
3. Achieve the above two points without changing the direction to rtl of the whole layout
To start the Navigation drawer from right to left
Set DrawerLayout tools:openDrawer="end"
Set NavigationView android:layout_gravity="end"
mDrawerToggle.setToolbarNavigationClickListener {
if (binding.drawerLayout.isDrawerOpen(GravityCompat.END)) {
binding.drawerLayout.closeDrawer(GravityCompat.END)
} else {
binding.drawerLayout.openDrawer(GravityCompat.END)
}
}
To set the Hamburger menu to the right
Set AppBarLayout android:layoutDirection="rtl"
