reddit app

Reddit Android App Development with Source Code. 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: 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: reddit android app development The finalized UI of the card layout looks like the following: The XML code to be added in a new layout file named item_spot.xml to achieve such a layout as shown above is as follows: <android.support.v7.widget.CardView xmlns:android"http://schemas.android.com/apk/res/android"

the data from Reddit. Before calling an Asynctask, we much know from which URL we are going to fetch data. As per Reddit API we can easily fetch a public data, subject to a limit of maximum 100 feeds at a time. By simply adding /.json&afterafter_tag&limit100 as a suffix to any of its URL. .json is used to get data in JSON format (you can get in XML) after and before tag parameters are used in case of pagination. It is useful,if the user wants to view more than 100 feeds. Limit: The number can be any upto 100. We're using 50 in our example to make it easier for our app to handle data. @SuppressLint("StaticFieldLeak") public class getFeed extends AsyncTask { @Override protected void onPreExecute() { super.onPreExecute(); progressDialog new ProgressDialog(MainActivity.this); progressDialog.setMessage("Getting Feed..."); progressDialog.show(); } @Override protected String doInBackground(String... strings) { OkHttpClient client new OkHttpClient(); if(strings.length !
