So I want to hide navigation properly then go to new activity .And I am not using number of fragment with activity. I am using total activity with navigation drawer.

Answer 1

Use

mDrawerLayout.closeDrawers();

if you want to close drawer and then launch another Activity add delay using Handler

 new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {
                //launch activity here
            }
        },TIME_IN_MILLI_SEC)

Answer 2

You can try closing your drawer when a item is selected:

navigationView.setNavigationItemSelectedListener(
      new NavigationView.OnNavigationItemSelectedListener() {
          @Override
          public boolean onNavigationItemSelected(MenuItem menuItem) {
              menuItem.setChecked(true);
              //saving the id of the item selected
              itemSelected = menuItem.getItemId();
              mDrawerLayout.closeDrawers();
              return true;
          }
});

Then you can use a DrawerLayout.DrawerListener. On the onDrawerClosed you can start your Activity

@Override    
public void onDrawerClosed(View drawerView) {
        if (itemSelected >= 0) {
            Class activityClass = null;
            switch (itemSelected) {
                case R.id.itemId:
                    activityClass = MyActivity.class;
                    break;
                //same for any other item
            }
            if (activityClass != null) {
                Intent intent = new Intent(this, activityClass);
                startActivity(intent);
                finish();
            }
        }
    }
