+# View Pager(2) dots indicator
+
+This repository was created to present you implemented dots indicator
+either for `ViewPager` or `ViewPager2`.
+
+
+## How to implement View Pager dots indicator?
+
+All we need are: [ViewPager][1], [TabLayout][2] and 2 drawables for
+selected and default dots.
+
+Firstly, we have to add `TabLayout` to our screen layout, and connect it
+with `ViewPager`. We can do this in two ways:
+
+
+### Nested `TabLayout` in `ViewPager`
+
+```xml
+
+
+
+
+```
+
+> In this case `TabLayout` will be automatically connected with
+> `ViewPager`, but `TabLayout` will be next to `ViewPager`, not over it.
+
+### Separate `TabLayout`
+
+```xml
+
+
+
+```
+
+> In this case, we can put `TabLayout` anywhere, but we have to connect
+> `TabLayout` with `ViewPager` programmatically
+
+```java
+ViewPager pager = (ViewPager) view.findViewById(R.id.photos_viewpager);
+PagerAdapter adapter = new PhotosAdapter(getChildFragmentManager(), photosUrl);
+pager.setAdapter(adapter);
+
+TabLayout tabLayout = (TabLayout) view.findViewById(R.id.tab_layout);
+tabLayout.setupWithViewPager(pager, true);
+```
+
+Once we created our layout, we have to prepare our dots. So we create
+three files: `selected_dot.xml`, `default_dot.xml` and
+`tab_selector.xml`.
+
+### selected_dot.xml
+
+```xml
+
+
+ -
+
+
+
+
+
+```
+
+### default_dot.xml
+
+```xml
+
+
+ -
+
+
+
+
+
+```
+
+### tab_selector.xml
+
+```xml
+
+
+
+
+
+
+
+```
+
+---
+
+Now we need to add only 3 lines of code to `TabLayout` in our XML
+layout.
+
+```xml
+app:tabBackground="@drawable/tab_selector"
+app:tabGravity="center"
+app:tabIndicatorHeight="0dp"
+```
