I have navigation drawer, and a button on the toolbar that when you click it it opens it and make some kind of nice animation.
I'm trying to move the button from the right side to the left side, but unsuccessfully.
I tried to change the gravity of it from start to end, but it didn't change it.
It was made by a template of android studio.
Moreover, when I click this Button it crashes me.
when I change the "android:supportsRtl" to false, it changes the side of the button to the left, as I want, but it then changes the side of the drawer as well.
and I also need to supportsRTL, so it's not a good solution. (I set it to "true" on the manifest)
What is the problem? and How can I get the Navigation Icon on the left side, with the nice animation?
BTH, how can I make the navigation be a little bit smaller(that I can see the toolbar) ?

Just use a custum view in the toolbar if you want something as custom as having the drawer toggle in the opposite side of the drawer.
Uppon click:
mDrawerLayout.closeDrawer(GravityCompat.START);
mDrawerLayout.openDrawer(GravityCompat.START);
And for the toolbar - you can just put the drawer below the toolbar in a vertical LinearLayout
In main activity add these lines:
android:layoutDirection="rtl"
android:textDirection="anyRtl"

I tried different method, but each time my application crashes. Someone would have an idea of the problem? I have to do this on homework for school and I do not know how to solve this problem.
You are trying to cast LinearLayout into a ConstraintLayout
Change line LinearLayout paramLayout; to ConstraintLayout paramLayout; in your activity
So I recently implemented a navigation drawer in my app. Along with Navigation drawer I also implemented menu items to access options like settings. However, I want to keep this floating action button on all the Navigation drawer pages but I don't want to have it on my settings page which is accessed from menu. Here is the current code that I have.
The on create for the nav bar.
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_nav_drawer);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
//Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
//.setAction("Action", null).show();
Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.putExtra(Intent.EXTRA_TEXT, "This is my text to send.");
sendIntent.setType("text/plain");
startActivity(Intent.createChooser(sendIntent, getResources().getText(R.string.send_to)));
}
});
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);
}
Then this is the code for the floating action button itself in the app_bar_nav_drawer.xml
<?xml version="1.0" encoding="utf-8"?>

android:layout_gravity="bottom|end"
android:layout_margin="#dimen/fab_margin"
app:srcCompat="#drawable/ic_menu_share"/>
</android.support.design.widget.CoordinatorLayout>
Here is the code for the settings_layout.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" android:layout_height="match_parent">
<TextView
android:text="Use Cell Data to retrieve driving data:"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/textView"
android:textSize="18sp"
android:textColor="#color/cast_expanded_controller_background_color"
android:layout_alignParentTop="true"
android:layout_alignParentStart="true" />
<RadioGroup
android:layout_width="89dp"
android:layout_height="69dp"
android:weightSum="1"
android:layout_below="#+id/textView">
<RadioButton
android:text="Enable"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/radioButton7"
android:layout_weight="1" />
<RadioButton
android:text="Disable"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/radioButton6"
android:layout_weight="1"
android:checked="true" />
</RadioGroup>
</RelativeLayout>
Just an FYI I want to keep this for the menu pages only, not the settings page. Let me know if I can add anymore code that would help.

You could add "fab.setVisibility(View.GONE)" to the OnCreate only in those Activities where it should be hidden
Hope this helped
Here is the solution I found best for me
#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();
FragmentManager fragmentSettingsManager = getFragmentManager();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
fragmentSettingsManager.beginTransaction().replace(R.id.content_frame, new SettingsFragment()).commit();
setTitle(R.string.action_settings);
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setVisibility(View.GONE);
}
return super.onOptionsItemSelected(item);
}
#SuppressWarnings("StatementWithEmptyBody")
#Override
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
FragmentManager fragmentManager = getFragmentManager();
if (id == R.id.nav_first_layout) {
fragmentManager.beginTransaction().replace(R.id.content_frame, new FirstFragment()).commit();
setTitle(R.string.speed_graph);
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setVisibility(View.VISIBLE);
} else if (id == R.id.nav_second_layout) {
fragmentManager.beginTransaction().replace(R.id.content_frame, new SecondFragment()).commit();
setTitle(R.string.drive_player);
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setVisibility(View.VISIBLE);
} else if (id == R.id.nav_third_layout) {
fragmentManager.beginTransaction().replace(R.id.content_frame, new ThirdFragment()).commit();
setTitle(R.string.google_maps);
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setVisibility(View.VISIBLE);
} else if (id == R.id.nav_share) {
Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.putExtra(Intent.EXTRA_TEXT, "Go Check Out All Driving Data in the Play Store!");
sendIntent.setType("text/plain");
startActivity(Intent.createChooser(sendIntent, getResources().getText(R.string.send_to)));
}
Best practice is to handle such cases using interfaces.
So first create an interface.
FabVisibilityController.java
public interface FabVisiblityController{
toggleVisibility(boolean visibility);
}
Then in your main class
NavigationDrawerActivity.java
public class NavigationDrawerActivity extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener, FabVisibilityController{
//write this code at the end of the class
#override
toggleVisibility(boolean visibility){
if(visibility)
fab.setVisibility(View.VISIBLE);
else
fab.setVisibility(View.GONE);
}
}
then in your settings fragment
public class SettingsFragment extends Fragment{
Context context;
FabVisibilityController controller;
//then in onAttach method
#override
onAttach(Context context){
this.context = context;
if(context instanceof FabVisibilityController)
controller = (FabVisibilityController) context;
}
//then in onResume Method
#override
onResume(){
super.onResume();
//this will hide FAB whenever settings page is called
controller.toggleVisibility(false);
}
}
Do the same in your other fragments, but only difference will be, controller.toggleVisibility(true) should be called in onResume() to make FAB visible.
I am using android studio 1.5.1. this version makes navigation drawer activity by its own:
<?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="start">
<include
layout="#layout/app_bar_main"
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="start"
android:fitsSystemWindows="true"
app:headerLayout="#layout/nav_header_main"
app:menu="#menu/activity_main_drawer" />
</android.support.v4.widget.DrawerLayout>
But the slider menu opens from left. I want to set it to open from write.
so I changed the above code to this code:
<?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="right">
<include
layout="#layout/app_bar_main"
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="right"
android:fitsSystemWindows="true"
app:headerLayout="#layout/nav_header_main"
app:menu="#menu/activity_main_drawer" />
</android.support.v4.widget.DrawerLayout>
so in the design mode, the drawer menu comes to the right position.
and I write this code (accourding to an answer in the stack overflow) in my MainActivity.java:
public class MainActivity extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener {
DrawerLayout drawer;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {

but when I run the program, in genymotion, the menu button is still on the left upper side and when I click on it, the program crash...
what is the problem and how can I set this menu to open from right?!
Try to not use ActionBarDrawerToggle class and in your R.menu.main, create a menu item (with a hamburger icon for example) which will be always visible for your Toolbar. When Activity is rendered, this menu item will be placed to the right in your Toolbar. So instead of using android.R.id.home, use your own menu item id when onOptionsItemSelected is called. And in your xml file, change android:layout_gravity="right" to android:layout_gravity="end". When you call drawer.openDrawer();, use the correct parameter accordingly for this method.
I'm using The last version of Android Studio (1.5) and I want to make a menu using Drawer Layout, for position its call GravityCompat.
I'm trying to use this components and modify it, putting the Drawer out from right to left. Here is my code.
public class MainActivity extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener {
#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);
}
#Override
public void onBackPressed() {
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
if (drawer.isDrawerOpen(GravityCompat.END)) {
drawer.closeDrawer(GravityCompat.END);
} 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.main, 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();
if (id == R.id.nav_camera) {
// Handle the camera action
} else if (id == R.id.nav_gallery) {
} else if (id == R.id.nav_slideshow) {
} else if (id == R.id.nav_manage) {
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.END);
return true;
}
}
The 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="start">
<include
layout="#layout/app_bar_main"
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="wrap_content"
android:layout_gravity="end"
android:fitsSystemWindows="true"
app:menu="#menu/activity_main_drawer" />
</android.support.v4.widget.DrawerLayout>
As you can see, GravityCompat don't let me to put right instead of END or START, and if I put it in the XML, it crash.
with the next error:
java.lang.IllegalArgumentException: No drawer view found with gravity LEFT
First of all replace on DrawerLayout the tools:openDrawer="start" with tools:openDrawer="end". Now your problem is on the toggle, which opens the left drawer, and because you have only right drawer it throws the exception. You can add your own button on the actionbar (on the right side) to open the drawer. To do that change your app_bar.xml like this
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout 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"
android:fitsSystemWindows="true">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<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" />
<FrameLayout
android:id="#+id/drawer_button"
android:layout_width="50dp"
android:layout_height="?attr/actionBarSize"
android:layout_alignParentRight="true"
android:clickable="true">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal|center_vertical"
android:src="#mipmap/ic_drawer" />
</FrameLayout>
</RelativeLayout>
</android.support.design.widget.AppBarLayout>
<include layout="#layout/content_main" />
</android.support.design.widget.CoordinatorLayout>
Then change your onCreate method from your Activity like this
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
findViewById(R.id.drawer_button).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// open right drawer
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.openDrawer(GravityCompat.END);
}
});
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
}
Also you can find the image for your drawer here or here.
I hope this will help you. :)
use a custom drawerLayout just like this :
public class TaskManagerDrawerLayout extends DrawerLayout {
public TaskManagerDrawerLayout(Context context) {
super(context);
}
public TaskManagerDrawerLayout(Context context, AttributeSet attrs) {
super(context, attrs);
}
public TaskManagerDrawerLayout(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
#Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
try {
return super.onInterceptTouchEvent(ev);
} catch (IllegalArgumentException e) {
e.printStackTrace();
return false;
}
}
#Override
public void closeDrawer(int gravity) {
super.closeDrawer(GravityCompat.END);
}
#Override
public void openDrawer(int gravity) {
super.openDrawer(GravityCompat.END);
}
}
After implementing left side navigation drawer change the following properties.
tools:openDrawer="start" in DrawerLayout
android:layout_gravity="end" in NavigationView
toolbar.setNavigationIcon (R.color.transparent); mDrawerToggle.setDrawerIndicatorEnabled (false);
toolbar.setNavigationOnClickListener (new View.OnClickListener () { #Override public void onClick(View view) { if (mDrawerLayout.isDrawerOpen (Gravity.END)) { mDrawerLayout.closeDrawer (Gravity.END); } else { mDrawerLayout.openDrawer (Gravity.END); } } });
