###



## Installation



### Step 1

Add the JitPack repository to your build file

```gradle

	allprojects {

		repositories {

			...

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

		}

	}

```



### Step 2

Add the dependency

```gradle

	dependencies {

		compile 'com.github.Andy671:Dachshund-Tab-Layout:v0.3.3'

	}

```



# 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:

```xml

 

	

```



Setup it with a ViewPager:

```java

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

	tabLayout.setupWithViewPager(yourViewPager);

```



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

```java

	//AvailableAnimatedIndicator - change it with available animated indicator



	AvailableAnimatedIndicator indicator = new AvailableAnimatedIndicator(tabLayout);

	tabLayout.setAnimatedIndicator(indicator);

```



## Center align

In **v0.3.2** I've added **ddCenterAlign** parameter. You can use it when you want to center the tabs in **scrollable** tabMode.

Working behavior from [Stackoverflow](https://stackoverflow.com/questions/33191794/android-tablayout-with-active-tab-always-at-center-just-like-in-play-newsstand) question.

```xml



```



## 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):

```java

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;

    }

}

```
