How to Set Navigation Drawer to Be Opened from Right to Left

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

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 :)

Android - Is Navigation Drawer from right hand side possible?

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.)

Android-NavigationView from right to 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. :)

How does Fragment Navigation Drawer open from right to left?

The problem is ActionBarDrawerToggle always expects the drawer to be on the side corresponding to Gravity.START. In most locales this is on the left side, hence it tries to open the drawer with Gravity.LEFT, but yours is on the other side so it throws an exception instead. Whether or not this seems like an intelligent design decision, it is what it is.

If you are following the Material Design guidelines, your drawer will cover the action bar when it opens (it might already be doing this). Specifically for this reason, I don't like using ActionBarDrawerToggle and don't find it particularly useful; the animation of the menu icon to an arrow is obscured by the drawer, and the other functionality is easy enough to implement directly in the activity. In your case, the animation might actually be useful if your drawer on the other side doesn't cover the icon, but then again you might not want the icon to animate at all anyway.

In your onCreate() method, all you need to do is

Call toolbar.setNavigationOnClickListener() (or set an OnClickListener on a view in your Toolbar) and have this listener toggle the drawer using drawerLayout.openDrawer(Gravity.RIGHT) and the equivalent closeDrawer() method.
Use drawerLayout.addDrawerListener() to add a listener. When the drawer opens or closes, you can use this listener to change things like the toolbar's icon and/or its contentDescription (for accessibility), or to do anything else you like
