BottomSlider like Uber


I really like uber's Bottom Slider a lot and i want to create a view like that.After searching, I found a great library do it easily. Here is the screenshot of the sample.





Step: 1
======

Add below line to build.gradle file under app folder and sync






compile 'com.github.lawloretienne:discreteslider:0.0.9'






Credits to the Author of the Library.

Step: 2

======

create a layout like below



activity_main.xml

=============








<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/main_content"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <FrameLayout
        android:id="@+id/container"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_weight="1"
        android:background="@color/grey_500"
        android:orientation="vertical">

    </FrameLayout>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom"
        android:background="@color/grey_100"
        android:orientation="vertical">

        <RelativeLayout
            android:id="@+id/tick_mark_labels_rl"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:paddingTop="8dp" />

        <com.etiennelawlor.discreteslider.library.ui.DiscreteSlider
            android:id="@+id/discrete_slider"
            android:layout_width="match_parent"
            android:layout_height="56dp"
            android:layout_marginBottom="4dp"
            android:background="@color/grey_100"
            android:paddingLeft="8dp"
            android:paddingRight="8dp"
            app:backdropFillColor="@color/grey_200"
            app:backdropStrokeColor="@color/grey_300"
            app:backdropStrokeWidth="1dp"
            app:horizontalBarThickness="4dp"
            app:position="0"
            app:progressDrawable="@drawable/transparent_progress_drawable"
            app:tickMarkCount="4"

            app:tickMarkRadius="8dp" />

    </LinearLayout>

</LinearLayout>








Step: 3

======

create a drawable with an image like below. I have created four files like this. please see source code for reference.



ubergo.xml

=========












<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

    <item>

        <shape xmlns:android="http://schemas.android.com/apk/res/android"
            android:shape="oval">

            <size
                android:width="40dp"
                android:height="40dp" />
            <stroke
                android:width="8dp"
                android:color="@color/fifty_percent_transparency_primary" />

            <solid android:color="@color/colorPrimary" />

            <corners android:radius="1dp" />

        </shape>
    </item>

    <item>

        <bitmap
            android:gravity="center"
            android:src="@drawable/ic_directions_car_black_24dp" />
    </item>


</layer-list>






Add all icons are added as an array in strings.xml file and we can use in MainActivity class.




<array name="icons">
    <item>@drawable/uber_pool</item>
    <item>@drawable/uber_moto</item>
    <item>@drawable/uber_go</item>
    <item>@drawable/uber_suv</item>
</array>







Step: 4

======

Create an Activity class and



MainActivity.java
