Open Navigation Drawer with Button Click

Question

I'm working with Navigation Drawer and I want to click the button on activity and Navigation Drawer should show, but I don't know how to do it. Normally, when we swipe from left edge to the right the navigation will be shown. as such, I want to be able to open the navigation drawer with the click of a button.

Navigation Bar and Navigation Drawer are different things: https://developer.android.com/training/system-ui/navigation.html — Darush, Oct 14 '17 at 15:43

Use the following methods to open and close your navigation drawer:

DrawerLayout drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);

//To Open:
drawerLayout.openDrawer(Gravity.START);

//To Close:
drawerLayout.closeDrawer(Gravity.END);

@Danh NavigationView is typically placed inside a DrawerLayout so you need to address your navigation drawer. – Darush Oct 14 '17 at 15:38
i still can't do this. can you please get into detail ? – Danh Oct 14 '17 at 15:43

 Button hamMenu = findViewById(R.id.ham_menu);

    hamMenu.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            DrawerLayout navDrawer = findViewById(R.id.drawer_layout);
            // If the navigation drawer is not open then open it, if its already open then close it.
            if(!navDrawer.isDrawerOpen(GravityCompat.START)) navDrawer.openDrawer(Gravity.START);
            else navDrawer.closeDrawer(Gravity.END);
        }
    });

You can also use a method and Use the exact same steps given by @Zeeshan.

public void hamMenu(View view){
    DrawerLayout drawer = findViewById(R.id.drawer_layout);
    if (!drawer.isDrawerOpen(GravityCompat.START)) {
        drawer.openDrawer(GravityCompat.START);
    } else {
        drawer.closeDrawer(GravityCompat.END);
    }
}

Use this method in the button which you need android:Onclick="hamMenu" in .xml.
