How to close navigation drawer when an item is pressed from it?

Ideally navigation drawer should get closed once some item has been pressed from it, but its not happening automatically. How to do it ? Thanks!

Got it!

private DrawerLayout mDrawerLayout;
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerLayout.closeDrawers();

Working perfectly fine.

For me this one worked -

mDrawerLayout.closeDrawer(Gravity.START, false);

DrawerLayout mDrawerLayout= (DrawerLayout) findViewById(R.id.drawer_layout)

closeDrawer(); // called when you want to close

public void closeDrawer() {
  if (mDrawerLayout.isDrawerOpen(GravityCompat.START)) {
    mDrawerLayout.closeDrawer(GravityCompat.START);
  }
}

If you have mDrawerLayout as your drawer layout, you can close it when it is open.

@Override
public void onBackPressed() {
    if (this.mDrawerLayout.isDrawerOpen(GravityCompat.START)) {
        this.mDrawerLayout.closeDrawer(GravityCompat.START);
    } else {
        super.onBackPressed();
    }
}
