Android-Timeline-View

Install

Add following to application level build.gradle file

dependencies {
    //...

    compile 'com.akshaykale.android:android-timeline-view:2.1'
}

Usage

Timeline view can be loaded directly as a Fragment.


Add a container to load the fragment.

activity_main.xml

<FrameLayout
        android:layout_marginTop="65dp"
        android:id="@+id/container"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

MainActivity.java

// instantiate the TimelineFragment
TimelineFragment mFragment = new TimelineFragment();

//Set data
mFragment.setData(loadData(), TimelineGroupType.MONTH);

//Set configurations
mFragment.addOnClickListener(this);

FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
transaction.replace(R.id.container, mFragment);
transaction.commit();

Load the data into Timeline using loadDataInTimeline() function

private ArrayList<TimelineObject> loadDataInTimeline() {
        //Load the data in a list and sort it by times in milli
        ArrayList<TimelineObject> objs = new ArrayList<>();
        objs.add(new TestO(Long.parseLong("1483196400000"), "A", "url"));
        objs.add(new TestO(Long.parseLong("1483196400000"), "A", "url"));
        objs.add(new TestO(Long.parseLong("1483196400000"), "B", "url" ));
        objs.add(new TestO(Long.parseLong("1483196400000"), "C" , "url"));
        objs.add(new TestO(Long.parseLong("1484146800000"), "D" ,c"url"));
        //Sort and return
        //Sort logic
        return objs;
    }

Load single object into timeline using addSingleObject() function

TestO object = new TestO(Long.parseLong("1481196400000"), "ZZZ", "http://www.pics4learning.com/images/categories/cat-biome-360.jpg");

mFragment.addSingleObject(object, TimelineGroupType.DAY);

TestO.java

Every data object must implement TimelineObject and override the methods and return valid value.

public class TestO implements TimelineObject {
    long timestamp;
    String name, url;

    @Override
    public long getTimestamp() {
        return timestamp;
    }
    @Override
    public String getTitle() {
        return name;
    }
    @Override
    public String getImageUrl() {
        return url;
    }
}


Use different image loading library

For Image loading this library uses Picasso, But you can use any library you preffer to load the image.
For this, create a class ImageLoad which implements ImageLoadingEngine

public class ImageLoad implements ImageLoadingEngine {
    @Override
    public void onLoadImage(ImageView imageView, String uri) {
          // Use any library you prefer to load the image into the view
          // For Ex: Glide, Picasso, UIL, etc.
    }
}

And before loading the fragment into the container add following line of code.

mFragment.setImageLoadEngine(new ImageLoad(getApplicationContext()));
