I think you can set current page to the last page using <code>viewPager.setCurrentItem()</code>. Then it will swipe left to right .. :)

blocks|key|241032|text|你已经可以在两个方向上滑动了。默认情况下，它显示第0页，但您可以对其进行更改：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|241033|protected+void+onCreate(Bundle+savedInstanceState)+{

You can swipe in both directions already. By default it shows page zero, but you could change that:

<pre><code>protected void onCreate(Bundle savedInstanceState) {
 // ...
 viewPager.setCurrentItem(myFragmentCount-1); 
 // ...
</code></pre>

blocks|key|24468|text|我确信这与op无关，但我找到了一个对我有效的解决方案(因为修改数据对我来说是一个问题)。我简单地将视图分页程序在Y轴上旋转了180度，然后在180度内再次旋转了它的子视图。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|24469|android.view.View

I'm sure it's not relevant for the op, but I found a solution that worked for me (as modifying the data was a problem for my case). 
I simply rotated the viewpager 180 degrees in the Y axis, and then rotated it's subviews again in 180.

<pre><code>android.view.View

public void setRotationY(float rotationY)
</code></pre>

Hope it helped anyone, as I think this is the most close to how Android mirrors all the os when change to rtl language.

I know this question is old, but here is my version of things:

In order to get your viewpager to swipe RTL , regardless if it has fragments or views inside it you need to do the following things

step 1:
define an integer: <code>R.integer.angle_rotation_for_rtl</code>

for <code>values</code> it is <code>0</code>

and for <code>values-rtl</code> it is <code>180</code>

step 2:

<pre><code>viewPager.setRotationY(getResources().getInteger(R.integer.angle_rotation_for_rtl)); 
</code></pre>

step 3:

<pre><code> viewPager.setPageTransformer(false, new ViewPager.PageTransformer() {
 @Override
 public void transformPage(@NonNull View page, float position) {
 page.setRotationY(getResources().getInteger(R.integer.angle_rotation_for_rtl));

 }
 });
</code></pre>

And the result - a smoothly working viewpager , no extra ifs

blocks|key|24419|text|首先，你需要在你的类中实现OnPageChangeListener，第二，像viewpager.setOnPageChangeListener(yourclass.this)；一样将监听器设置为你的视图页面，希望这能行得通。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|24420|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

First u need to implements OnPageChangeListener in your class
and second set the listener to your viewpager like
 viewpager.setOnPageChangeListener(yourclass.this);
Hope This will work.

blocks|key|241132|text|为了让你的水平ViewPager在LayoutDirection改变时像RecyclerView一样工作，只需将这个方法添加到你的自定义ViewPager中即可；|type|unstyled|depth|inlineStyleRanges|entityRanges|data|241133|public+class+LoopViewPager+extends+ViewPager+{

For letting your horizontal ViewPager behave like RecyclerView when LayoutDirection change just add this method to your custom ViewPager;

<pre><code>public class LoopViewPager extends ViewPager {
....
...
 public void setLayoutDirection(int layoutDirection) {
 if(layoutDirection == ViewCompat.LAYOUT_DIRECTION_LTR) {
 setRotationY(0);
 }
 else if(layoutDirection == ViewCompat.LAYOUT_DIRECTION_RTL) {
 setRotationY(180);
 }
}
</code></pre>

and where you use your viewPager set it dynamically like this;

<pre><code>viewPager.setLayoutDirection(context.getResources().getConfiguration().getLayoutDirection());
</code></pre>

blocks|key|241176|text|我完全理解这个问题已经得到了很好的回答；但是如果您正在使用RTL语言；例如，如果您有一本想要用ViewPager显示的书；那么除了答案之外，您还可以考虑翻页以获得正确的页面；为此，您可以修改ViewPager适配器的getItem()方法|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|241177|@Override
public+Fragment+getItem(int+position)+{

I totally understand that the question is answered perfectly; but if you're using RTL language; for instance if you have a book that you want to show in ViewPager; then besides the answer, you might also consider to flip the pages over to get the right page; to do that modify your ViewPager adapter's <code>getItem()</code> method

<pre><code>@Override
public Fragment getItem(int position) {
 return SomeFragment.newInstance(N_PAGES - position - 1); // to filp the pages
}
</code></pre>
