NavigationView on both side - android

I need to open navigation view on both side with different menu.. Also I need to change navigation icon (Currently with three horizontal line). This is better if I can open the nav_view and na_view2 with separate button clicks, these buttons are available in my toolbar, or I need to know how can I set separate icons on both side?.

Any help will be highly appreciable.

We can get buttons from toolbar by following lines,
Button btnStart = (Button) findViewById(R.id.btnStart);
Button btnEnd = (Button) findViewById(R.id.btnEnd);
and while click the start button we can open and hide left drawer by following listener,
btnStart.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (drawer.isDrawerOpen(GravityCompat.START))
drawer.closeDrawer(GravityCompat.START);
else drawer.openDrawer(GravityCompat.START);
}
});
and while click the end button we can open and hide right drawer by following listener,
btnEnd.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (drawer.isDrawerOpen(GravityCompat.END))
drawer.closeDrawer(GravityCompat.END);
else drawer.openDrawer(GravityCompat.END);
}
});
And our onBackPressed method will be
public void onBackPressed() {
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
if (drawer.isDrawerOpen(GravityCompat.START)) {
drawer.closeDrawer(GravityCompat.START);
} else if (drawer.isDrawerOpen(GravityCompat.END)) {
drawer.closeDrawer(GravityCompat.END);
} else {
super.onBackPressed();
}
}
This also used to close the drawers if those is in open state.

Navigation drawer: How do I set the navigation item selected listener with custom tool bar?

I don't see any error when I open the navigation drawer, but it keeps getting closed whenever I select an item. Edit: My drawer gets closed automatically on item selection without showing the Toast message as mentioned in NavigationItemSelectedListener. The toast message is not displayed.
I have used a custom toolbar in which I have added an image view as a side menu button.

I have tried other method with default toolbar, and it was working properly but I am not able to figur out the problem with custom toolbar. I wanted to display a toast on item selection inside the navigation drawer. Please help me find the solution...
Thank you.
In onNavigationItemSelected, Change this
return false;
to
return true;
After so long finally I found the solution to my problem. But I don't know why it was happening like that but I'm happy that it is finally working. And I am also very happy to share it with those who may experience the same issue in the future which I hope they won't.
I referred to the link from the Git hub for this solution. Link: https://github.com/priyalbhatewara123/Navigation-Drawer--Android
Finally here is the solution I found,
I just added the following lines of codes below </ScrollView> which was above <ScrollView> in the problematic code used in my activity_custom_toolbar.xml.

android:layout_width="wrap_content"

Always getting the error messsage: No drawer view found with gravity LEFT

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

app:menu="#menu/home_side_menu"

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)

How to add a back button to action bar / toolbar

I have written a piece of code as part of an app where I want to implement a back button on the action bar/tool bar such that when the button is pressed, the previous page (the page/fragment immediately before the current page/fragment) will be displayed.
This is the code for the ToolBar, DrawerLayout, NavigationView and getSupportActionBar():
final DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
final NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
android.support.v7.widget.Toolbar toolbar = (android.support.v7.widget.Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
toolbar.setVisibility(View.VISIBLE);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setLogo(R.mipmap.ic_launcher);
getSupportActionBar().setDisplayUseLogoEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
I am unable to use ActionBar. For some reason (I don't know why), my Android studio/ program, will not allow me to use the ActionBar. So I am substituting that with the set/getSupportActionBar().
The function used in relation to this are:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu_settings, 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();
switch (id) {
case android.R.id.home:
onBackPressed();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
#Override
public void onBackPressed() {
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
if (drawer.isDrawerOpen(GravityCompat.START)) {
drawer.closeDrawer(GravityCompat.START);
} else {
super.onBackPressed();
}
}
My activity_main.xml file is:

The problem is that I don't know which is the useful code, which is the useless code and how to mix/join/(add additional codes to) these (codes, methods, variables/objects, fragments, xml layouts) to get the desired outcome, that is, the application of a back button on the action bar/tool bar.
Most of the code above is implemented for the up button, not the back button. I have read at several places that up and back buttons are not the same.
I tried several links on internet as well as on this site, but none of them has just what I need.
Hope someone can give me an clear answer...
You can include the back icon in ToolBar:
Initialize ToolBar:
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
You can use an drawable icon as a back button.
toolbar.setNavigationIcon(R.drawable.your_drawable_icon);
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// what do you want here
}
});
If you do not want to use drawable icon then:
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowHomeEnabled(true);
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// what do you want here
}
});
Actually your layout having that issue because you have added toolbar in RelativeLayout so drawer layout is overlapping on it that's why you would not able to click on back arrow, i have fix your layout see below
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/activity_main"

android:orientation="vertical">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
app:navigationIcon="#drawable/ic_back_black"
app:popupTheme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:title="Settings" />
<android.support.v4.widget.DrawerLayout
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout
android:id="#+id/frame"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/toolbar" />
<android.support.design.widget.NavigationView
android:id="#+id/nav_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:menu="#menu/options_menu" />
</android.support.v4.widget.DrawerLayout>
</LinearLayout>
The simplest way would be to add parent activity in manifest file as developer docs suggest.
<activity
android:name=".ChildActivity"
android:parentActivityName=".ParentActivity" >
and java code you already have done it, setSupportActionbar and setHomeAsUpEnabled.
Edited :
its necessary to add up action for icon to be visible, as mentioned in
Android Developer Docs
So toolbar gives added flexibility to modify title-bar in Android.
As far as why getActionBar is not working and you are compelled to use getSupportActionBar is because you must be using SupportLibrary. SupportLibrary gives backward compatibility to earlier SDK versions.
If you want to modify your title-bar/header/action-bar extensively
then use toolbar otherwise use action-bar.
Add a navigation click listener to your toolbar , like below
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
onBackPressed();
}
});
If you are referencing some actions from the action bar, such as a Save action or a Share one, and you are overriding onOptionsItemSelected method, then you need to define the behavior when the back or home button is clicked:
#Override public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_save:
//save stuff
break;
//this is what you need to add to reference again back/home button
case android.R.id.home:
//do your stuff here, usually back to the home or close the current activity
getActivity().finish();
break;
default:
break;
}
return true;

How to load the drawer as in the image on a button click

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.

How to set Navigation Drawer to be opened from right to left

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. ;)

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.
DrawerLayout Properties
android:layout_gravity="right|end" and tools:openDrawer="end"

Java Code
// Appropriate Click Event or Menu Item Click Event
if (drawerLayout.isDrawerOpen(GravityCompat.END))
{
drawerLayout.closeDrawer(GravityCompat.END);
}
else
{
drawerLayout.openDrawer(GravityCompat.END);
}
//With Toolbar
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) {
//Gravity.END or Gravity.RIGHT
if (drawer.isDrawerOpen(Gravity.END)) {
drawer.closeDrawer(Gravity.END);
} else {
drawer.openDrawer(Gravity.END);
}
}
});
//...
}
In your layout file inside NavigationView set this attribute android:layout_gravity="end" and set tools:openDrawer="end" in the DrawerLayout
<?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"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".tasks.TasksActivity"
android:id="#+id/drawer_layout"
tools:openDrawer="end">
<!-- Navigation Drawer -->
<com.google.android.material.navigation.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/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"
