How to reverse viewpager swiping

So my app is in RTL, and with that, the tabs are now ordered from right to left..!

..But when I swipe to slide between the tabs, it contradicts the common sense, so I want to reverse it..! see the picture to see the problem..!

What I want is..! > when I'm in Tab1 and then I swipe from left to right I want it to slide to Tab 2 and so on..!

is that possible..!?

THE CODE

---

My Customer ViewPager

public class CustomViewPager extends android.support.v4.view.ViewPager{
private boolean enabled;

public CustomViewPager(Context context, AttributeSet attrs) {
    super(context, attrs);
    this.enabled = true;
}


@Override
public boolean onTouchEvent(MotionEvent event) {
    if (this.enabled) {
        return super.onTouchEvent(event);
    }

    return false;
}

@Override
public boolean onInterceptTouchEvent(MotionEvent event) {
    if (this.enabled) {
        return super.onInterceptTouchEvent(event);
    }

    return false;
}

public void setPagingEnabled(boolean enabled) {
    this.enabled = enabled;
 }
 }

My TabActivity (Helper Class)

  public class TabbedActivity extends BaseActivity { 

 //I extend BaseActivity to avoid repeating UI code like toolbar and stuff..

protected CustomViewPager viewPager;
public OrdersAdapter adapter;
public TabLayout tabs;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    tabs.setTabGravity(TabLayout.GRAVITY_FILL);
    viewPager.setAdapter(adapter);
    viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabs));


    tabs.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {

        @Override
        public void onTabSelected(TabLayout.Tab tab) {
            setTabSelected(tab);
        }


        @Override
        public void onTabUnselected(TabLayout.Tab tab) {

        }

        @Override
        public void onTabReselected(TabLayout.Tab tab) {

        }
    });
  }


public void setTabSelected(TabLayout.Tab tab) {
    viewPager.setCurrentItem(tab.getPosition());
}

public void addTab(int title) {

    tabs.addTab(tabs.newTab().setText(getString(title)));

}

}

My Activity that contains the Tablayout and has three fragments, one for each tab.

public class MyOrders extends TabbedActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    setContentView(R.layout.activity_orders);

    tabs = (TabLayout) findViewById(R.id.tab_layout);
    addTab(R.string.NewOrderTabTitle); //tab1
    addTab(R.string.MyOrderTabTitle); // tab2
    addTab(R.string.FinOrderTabTitle); //tab3

     adapter = new OrdersAdapter(getSupportFragmentManager(), tabs.getTabCount());
    viewPager = (CustomViewPager) findViewById(R.id.pager);
    viewPager.setPagingEnabled(true);

    tabs.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
        @Override
        public void onTabSelected(TabLayout.Tab tab) {
            viewPager.setCurrentItem(tab.getPosition());

        }

        @Override
        public void onTabUnselected(TabLayout.Tab tab) {

        }

        @Override
        public void onTabReselected(TabLayout.Tab tab) {

        }
    });

    viewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
        @Override
        public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
        }

        @Override
        public void onPageSelected(int position) {

        }

        @Override
        public void onPageScrollStateChanged(int state) {

        }
    });

    super.onCreate(savedInstanceState);


 }
}

adding the tabs in the reverse order, and then use viewPager.setCurrentItem(adapter.getCount() - 1); to select the last tab.

based on your comment, here's what I did in the Activity that has tablayout

 //code...
 tabs = (TabLayout) findViewById(R.id.tab_layout);
    addTab(R.string.FinOrderTabTitle); //tab3
    addTab(R.string.MyOrderTabTitle); // tab2
    addTab(R.string.NewOrderTabTitle); //tab1
 //code...

 viewPager.setCurrentItem(adapter.getCount() - 1);

This is a little tricky, the android viewPager from right to left has a little bug, only the page titles are from right to left and the pages themselves don't.

In order to fix this, what I did was using the regular left to right layout and adding the tabs in the reverse order, and then use viewPager.setCurrentItem(adapter.getCount() - 1); to select the last tab.

This is how the result should look like: https://drive.google.com/open?id=0B0FzrLgjet7pSE9lMFFFT0JiekE

where size is the first tab, the display is the second and so on

To keep RTL behavior and the LTR behavior you should use this:

Configuration config = getResources().getConfiguration();
if (config.getLayoutDirection() == View.LAYOUT_DIRECTION_RTL)
{
     //use the RTL trick here
}
else
{
     //use the regular case here
}
