Android Arsenal Release Awesome

Sample:

Sample Gif Sample Gif

A slider view.

This project is an attempt to port the svg pod slider created by Chris Gannon to android. see CodePen

version 1.2.0 Update:

  • Major enhancements in how animations are done.
  • Added a ease out elastic effect(a wobble effect just before the circles stop).

Gradle:

Add it to your project build.gradle with:

allprojects {
    repositories {
        maven { url "https://jitpack.io" }
    }
}

and to your module's build.gradle dependencies block add the dependency to the library:

P.S Check Jitpack badge at the top of the readme for the latest version name.

dependencies {
    compile 'com.github.bhargavms:PodSLider:X.X.X'
}

Usage

Xml Attributes

app:mainSliderColor="@color/mainPodSlider" <!-- the color of the main rounded rectangular bar. -->
app:numberOfPods="2" <!-- the number of small circles (i.e pods) in the slider.-->
app:podColor="#4CAF50" <!-- the color of the pod when its not selected.-->
app:selectedPodColor="#fff" <!-- the color of the pod when its selected.-->

Setting a click listener

PodSlider podSlider = (PodSlider) findViewById(R.id.pod_slider);
podSlider.setPodClickListener(new OnPodClickListener() {
    @Override
    public void onPodClick(int position) {
        Log.d("PodPosition", "position = " + position);
    }
});

To set Currently selected Pod

podSlider.setCurrentlySelectedPod(1);
// if you want to change selected pod and also animate
// then use the below method, But please remember to use this only after
// the view has been rendered (i.e donot use this in onCreate()/onCreateView()
// this will cause the large and medium circle to be drawn at (0, height/2)
podSlider.setcurrentlySelectedPodAndAnimate(1);

To set up with a ViewPager

By default, the widget uses the String returned by the viewpager adapter's getPageTitle(int) method, to disable it just set pager.usePageTitle(false) as false, before setting up with viewPager

ViewPager pager = (ViewPager) findViewById(R.id.pager);
PodSlider pagerSlider = (PodSlider) findViewById(R.id.pager_slider);
PodPagerAdapter adapter = new PodPagerAdapter(getSupportFragmentManager());
pager.setAdapter(adapter);
pagerSlider.setUpWithViewPager(pager);

To change the number of pods programatically

podSlider.setNumberOfPods(4);

To set custom text

// Use this after setting number of pods and make sure the length of texts 
// array is equal to or greater than `numberOfPods` that you set using `setNumberOfPods()`
podSlider.setPodTexts(new String[]{"A", "B", "C", "D", "E", "F", "G", "H", "I", "J"});

(ideally use single character don't ever have texts with more than 1 char looks ugly)

To set Drawables

Drawable access = getResources().getDrawable(R.drawable.ic_accessibility_black_24dp);
Drawable account = getResources().getDrawable(R.drawable.ic_account_circle_black_24dp);
Drawable car = getResources().getDrawable(R.drawable.ic_directions_car_black_24dp);
// Use this after setting number of pods and make sure the length 
// of drawables array is equal to or greater than `numberOfPods`
// that you set using `setNumberOfPods()`
podSlider.setPodDrawables(
        new Drawable[]{
                access, account, car,
                access, account, car,
                access, account, car,
                access
        }, PodSlider.DrawableSize.FIT_POD_CIRCLE
);

I have not added (and do not plan to in the near future) support for passing in drawable resource Ids, loading the drawable from resource/creating it from bitmaps or whatever is left to you, if you want further customization on deciding the size of the drawable please open an issue, based on the amount of traction it receives I might decide to implement it.
