Installation

Step 1

Add the JitPack repository to your build file

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

Step 2

Add the dependency

    dependencies {
        compile 'com.github.Andy671:Dachshund-Tab-Layout:v0.2.0'
    }

Usage

DachshundTabLayout is a subclass of TabLayout, so usage is pretty similar. The most of the original methods should work without any problems. See sample and source code for more info.

Add DachshundTabLayout to xml (after the Toolbar in the AppBarLayout), if you have TabLayout simply replace it:

 <android.support.design.widget.AppBarLayout
 ...
    <android.support.v7.widget.Toolbar           
    .../>
    <com.kekstudio.dachshundtablayout.DachshundTabLayout
        android:id="@+id/tab_layout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>

Setup it with a ViewPager:

    DachshundTabLayout tabLayout = (DachshundTabLayout) findViewById(R.id.tab_layout);
    tabLayout.setupWithViewPager(yourViewPager);

If you want to change animated indicator (see Available Animated Indicators):

    //AvailableAnimatedIndicator - change it with available animated indicator

    AvailableAnimatedIndicator indicator = new AvailableAnimatedIndicator(tabLayout);
    tabLayout.setAnimatedIndicator(indicator);

Creating custom AnimatedIndicator

If you want to create your own custom AnimatedIndicator - you can implement AnimatedIndicatorInterface and if you want to use animators - AnimatorUpdateListener (See JavaDoc of AnimatedIndicatorInterface for more info):

public class CustomIndicator implements AnimatedIndicatorInterface, ValueAnimator.AnimatorUpdateListener {

    private DachshundTabLayout dachshundTabLayout;

    public CustomIndicator(DachshundTabLayout dachshundTabLayout){
        this.dachshundTabLayout = dachshundTabLayout;

        //here set-up your Animators, Paints etc.
    }

    @Override
    public void onAnimationUpdate(ValueAnimator animator) {
        // when animator updates - invalidate your canvas, and draw what you want.
    }

    @Override
    public void setSelectedTabIndicatorColor(@ColorInt int color) {
        // customization of color
    }

    @Override
    public void setSelectedTabIndicatorHeight(int height) {
        // customization of height
    }

    @Override
    public void setIntValues(int startXLeft, int endXLeft,
                             int startXCenter, int endXCenter,
                             int startXRight, int endXRight){
        // X-positions of the target and current tabs
    }

    @Override
    public void setCurrentPlayTime(long currentPlayTime) {
        // current play time of the animation
    }

    @Override
    public void draw(Canvas canvas) {
        //Make your draw calls here
    }

    @Override
    public long getDuration() {
        return DEFAULT_DURATION;
    }
}
