## QuickStart ##

### Include the Gradle dependency ###

```java

dependencies {

    compile 'com.github.adityagohad:HorizontalPicker:1.0.1'

}

```

Don't forget to add following to build.gradle(Project:{your_project_name>})

```

allprojects {

    repositories {

        jcenter()

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

    }

}

```

## How to use ##

Your picker will be recyclerView and this lib is just a custom layout manager

to initialize the PickerLayoutManager and set the properties

```java

PickerLayoutManager pickerLayoutManager = new PickerLayoutManager(this, PickerLayoutManager.HORIZONTAL, false);

pickerLayoutManager.setChangeAlpha(true);

pickerLayoutManager.setScaleDownBy(0.99f);

pickerLayoutManager.setScaleDownDistance(0.8f);

```

To make it snap to centre use ```SnapHelper```

```java

SnapHelper snapHelper = new LinearSnapHelper();

snapHelper.attachToRecyclerView(recyclerView);

```

set layout manager of your recyclerVew

```java

recyclerView.setLayoutManager(pickerLayoutManager);

```

To get selected view use ```onScrollStopListener```

```java

pickerLayoutManager.setOnScrollStopListener(new PickerLayoutManager.onScrollStopListener() {

    @Override

        public void selectedView(View view) {

            //Do your thing

        }

    });

}

```

## Don't forget this ##

To its core it is a recycler view with custom layout manager so if you forget to add ``` clipToPadding="false" ``` you will never be able to select first and last few elemets(values/views).


So always add paddingLeft and paddingRight like shown below. 

```

    

```
