Installation

 $ ant release

In order to use it within your (ant) project add this line to the project.properties

android.library.reference.1=path/to/android-preferences

Usage

• Add the page indicator to your layout

    <de.firebirdberlin.pageindicator.PageIndicator
        xmlns:pageindicator="pageindicator"
        android:id="@+id/page_indicator"
        android:background="#000000"
        android:layout_width="match_parent"
        android:layout_marginTop="5dp"
        android:layout_marginBottom="5dp"
        android:layout_height="6dp"
        pageindicator:color="android:attr/textColor"/>

Without specification the default color is the default android text color. You can
specify the color using the attribute `pageindicator:color`. Valid values are:
    - Resources in the form "package:type/name", e.g. "android:attr/textColor"
    - Colors in HEX-notation, e.g. "#00FF00"

The size is determined by the height of the view.

• Configure the page indicator in your class:

import de.firebirdberlin.pageindicator.PageIndicator;

[...]

final PageIndicator pageIndicator = (PageIndicator) findViewById(R.id.page_indicator);
pageIndicator.setPageCount(num_pages);
pager.setOnPageChangeListener(new OnPageChangeListener() {
   public void onPageScrollStateChanged(int state) {}
   public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {}

   public void onPageSelected(int position) {
       pageIndicator.setCurrentPage(position);
   }
});
