A small, simple, animated page indicator without the need for a viewpager.
I built this library because I was tired of all the existing page indicators out there to require a viewpager as this prevented me from using in on an Android Wear project that time.
To use this view just include it in your depencencies using
repositories {
...
maven { url "https://jitpack.io" }
}in your project build.gradle file and
dependencies {
compile 'com.github.markusressel:PageIndicatorView:v1.0.0'
}in your desired module build.gradle file.
After successfull gradle build you will be able to use this in your xml layout files
<de.markusressel.android.library.pageindicatorview.PageIndicatorView
android:id="@+id/pageIndicator"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>If you want you can change the style of the indicators by using attributes
<de.markusressel.android.library.pageindicatorview.PageIndicatorView
android:id="@+id/pageIndicator"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="0"
android:paddingTop="@dimen/activity_vertical_margin"
app:piv_activeIndicatorFillColor="?attr/colorAccent"
app:piv_activeIndicatorFillSize="20dp"
app:piv_activeIndicatorStrokeColor="@android:color/white"
app:piv_activeIndicatorStrokeWidth="5dp"
app:piv_inactiveIndicatorFillColor="?attr/colorAccent"
app:piv_inactiveIndicatorFillSize="15dp"
app:piv_inactiveIndicatorStrokeColor="@android:color/darker_gray"
app:piv_inactiveIndicatorStrokeWidth="10dp"
app:piv_pageCount="5" />You can also set these values in code using the following methods:
pageIndicator.activeIndicatorSize = pxFromDp(this, activeIndicatorSize)
pageIndicator.activeIndicatorFillColor = activeIndicatorColorFill
pageIndicator.activeIndicatorStrokeColor = activeIndicatorColorStroke
pageIndicator.activeIndicatorStrokeWidth = pxFromDp(this, activeIndicatorStrokeWidth)
pageIndicator.inactiveIndicatorSize = pxFromDp(this, inactiveIndicatorSize)
pageIndicator.inactiveIndicatorFillColor = inactiveIndicatorColorFill
pageIndicator.inactiveIndicatorStrokeColor = inactiveIndicatorColorStroke
pageIndicator.inactiveIndicatorStrokeWidth = pxFromDp(this, inactiveIndicatorStrokeWidth)
pageIndicator.indicatorGap = pxFromDp(this, indicatorGap)
pageIndicator.pageCount = pageCount
pageIndicator.setCurrentPage(initialPageIndex) // animated
pageIndicator.setCurrentPage(initialPageIndex, false) // not animatedTo be able to react to "OnClick" events on indicators, you can set a OnIndicatorClickedListener like this:
pageIndicator.setOnIndicatorClickedListener(object : OnIndicatorClickedListener {
override fun onIndicatorClicked(pageIndicatorView: PageIndicatorView, index: Int) {
// set the indicator view to the clicked position
pageIndicatorView.setCurrentPage(index, true)
// set your view pager to the clicked position
viewPager.currentItem = index
}
