The object class is your typical list item e.g User.class 35 | 36 | Let's say you want to display 3 different kind of views. A **user view**, a **banner view** and a **header view**. 37 | 38 | ##### First step 39 | Create a binder for each view type by extending the **Binder** class, like so: 40 | 41 | ```java 42 | 43 | //Extend the binder by adding the viewholder and list item class of your view 44 | public class UserBinder extends Binder { 45 | 46 | @Override 47 | public void onBindViewHolder(UserViewHolderHolder holder, User user, int position) { 48 | holder.textView.setText(user.getName()); 49 | } 50 | } 51 | ``` 52 | Do the same for your other views 53 | 54 | ##### Last step 55 | That's pretty much it. Just use the binder to your adapter like so: 56 | 57 | ```java 58 | 59 | //set the list item class, viewholder class and the view layout id 60 | UserBinder userBinder = new UserBinder(User.class, UserViewHolderHolder.class, R.layout.layout_user) 61 | 62 | new LeastAdapter.Builder() 63 | .binder(userBinder) 64 | ... 65 | //add more views 66 | ``` 67 | Check the example for more 68 | 69 | # Proguard 70 | ``` 71 | -keep class * extends io.c0nnector.github.least.Binder { *; } 72 | ``` 73 | 74 | # Install 75 | **1. Add it in your build.gradle at the end of repositories:** 76 | 77 | ``` 78 | repositories { maven { url "https://jitpack.io" } } 79 | ``` 80 | 81 | **2. Add the dependency in the form** 82 | 83 | ``` 84 | implementation 'com.github.ArthurSav:Least:master-SNAPSHOT' 85 | ``` 86 | -------------------------------------------------------------------------------- /app/src/main/java/io/c0nnector/github/least/example/MainActivity.java: -------------------------------------------------------------------------------- 1 | package io.c0nnector.github.least.example;
