Reddit Android App Development with Source Code.
Need some career advice or prepping for an Android developer interview? Hit me up on Topmate.io, and let's chat!
In this tutorial of Build that App. We will teach you how you can create your Reddit App in Android Studio using Java Programming Language.
However this app won’t be like the original Reddit App available in the play store. Rather it will have a swipe layout just like popular dating app Tinder. Which means you will be able to swipe your feeds in any direction.
For this we will be using yuyakaido library CardStackViewto achieve the desired layout.
Reddit Android App Development
Getting Started
Create a new Android Studio Project with Empty Activity. Go to build.gradle (app) and add following dependencies:
//TinderCards Library
implementation "com.yuyakaido.android:card-stack-view:2.2.1"
//Picasso
implementation 'com.squareup.picasso:picasso:2.71828'
//OKHTTP
implementation 'com.squareup.okhttp3:okhttp:3.12.1'
//Glide
implementation 'com.github.bumptech.glide:glide:4.8.0'
//GSON
implementation 'com.google.code.gson:gson:2.8.2'Making Layouts
Once the build Sync is finished, go to activity_main.xml in the res folder (See on the left side in the Project Panel). And add the following lines of code to it inside the ConstraintLayout Widget:
<com.yuyakaido.android.cardstackview.CardStackView
android:id="@+id/card_stack_view"
android:layout_width="match_parent"
android:layout_height="match_parent" />We’ve now added the CardStackView, this is where the cards will be displayed. Now let’s make the layout for our cards.
Here is the rough draft of how our card will look like:
The finalized UI of the card layout looks like the following:
