PageIndicatorView
PageIndicatorViewis light library to indicate ViewPager's selected page with different animations and ability to customise it as you need.
Integration
To add
pageindicatorviewto your project, first make sure in root
build.gradleyou have specified the following repository:
groovy
repositories {
jcenter()
}
Note: by creating new project in Android Studio it will have
jcenterrepository specified by default, so you will not need to add it manually.
Once you make sure you have
jcenterrepository in your project, all you need to do is to add the following line in
dependenciessection of your project
build.gradle.
See latest library version
groovy implementation 'com.romandanylyk:pageindicatorview:X.X.X'If your project already use
appcompat-v7support library, you can omit
PageIndicatorViewdependencies by adding a single .aar file to your project, that will decrease total amount of methods used in your project.
implementation 'com.romandanylyk:pageindicatorview:[email protected]'
Keep in mind, that
PageIndicatorViewhas min API level 14 and these dependencies:
implementation 'com.android.support:appcompat-v7:27.1.1' implementation 'com.android.support:recyclerview-v7:27.1.1' implementation 'com.android.support:support-core-ui:27.1.1'
Usage Sample
Usage of
PageIndicatorViewis quite simple. All you need to do is to declare a view in your
layout.xmland call
setSelectionmethod to select specific indicator - that's it!
PageIndicatorView pageIndicatorView = findViewById(R.id.pageIndicatorView);
pageIndicatorView.setCount(5); // specify total count of indicators
pageIndicatorView.setSelection(2);
But if you're as lazy as I'm - then there is another option to handle
PageIndicatorView
All the
piv_attributes here are specific for
PageIndicatorViewso you can customise it as you want with attributes - pretty handy.
But what is more important here is
app:piv_viewPager="@id/viewPager". What it actually do is catch up your
ViewPagerand automatically handles all the event's to selected the right page - so you don't need to call
setSelectionmethod on your own.
Another handy options here that works with your
ViewPageras a whole is
app:piv_dynamicCount="true"and
app:piv_interactiveAnimation="true"
Dynamic count will automatically updates
PageIndicatorViewtotal count as you updates pages count in your
ViewPager- so that's pretty useful.
While interactive animation will progress the animation process within your swipe position, which makes animation more natural and responsive to end user.
Note: Because
setViewPagerIduses an instance ofViewPager, using it in recycler could lead to id conflicts, soPageIndicatorViewwill not know properly what is the rightViewPagerto work with. Instead you should handle selected indicators on your own programatically.
pager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
@Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {/*empty*/}
@Override
public void onPageSelected(int position) {
pageIndicatorView.setSelection(position);
}
@Override
public void onPageScrollStateChanged(int state) {/*empty*/}
});
Here you can see all the animations
PageIndicatorViewsupport.
