ThisIsNSH / Candyview

The easiest way to implement RecyclerView in just 1 Line.

Delicious Facts 🍭

• Forget creation of tasteless Adapters & monotonous findViewById for your views in adapter.
• Text data String, int, float ... is automatically set into TextView & Button
• Image URL String and Image Drawable (int) R.drawable.id is automatically set into ImageView
• Its all done without any extra line of code. How?
• Manage properties of all view using single SugarListener or just set attributes for specific views.

Download via Gradle 💻

Add it in your Project build.gradle at the end of repositories:

allprojects {
  repositories {
    maven { url 'https://jitpack.io' }
  }
}

Add the dependency in your App build.gradle:

dependencies {
  implementation 'com.github.ThisIsNSH:CandyView:1.3'
  // add these for internal functioning
  implementation 'com.squareup.picasso:picasso:{latest version}'
  implementation 'com.android.support:recyclerview-v7:{build version}'
}

Get Started 🏁

1. Add the code to create CandyView:

<?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"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <com.thisisnsh.sugarlibrary.CandyView
        android:id="@+id/candy"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

</LinearLayout>

class ExampleActivity extends Activity {

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    ...

    // Initialize CandyView object
    CandyView candyView = findViewById(R.id.candy);

    // Create RecyclerView using make(Context content, int Layout, List<Model> Data, Model Class)
    candyView.make(this, R.layout.adapter, dataList, Model.class);

  }

}

2. Add SugarListener to explicitly set properties of views accessed using getViewById:

class ExampleActivity extends Activity implements CandyView.SugarListener {

  TextView textView;

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    ...
    candyView.addSugarListener(this);
  }

  @Override
  public void onCandyMade() {

    // Initialize required adapter views 
    textView = (TextView) candyView.getViewById(R.id.text);

  }

  @Override
  public void onCandyRecycled(View view, int position) {

    // Set attributes of adapter views for all positions
    textView.setTextColor(getResources().getColor(R.color.colorPrimary));

    // Set attributes of adapter views at a particular position
    if (position == 1)
      textView.setTextColor(getResources().getColor(R.color.colorAccent));

  }

}

Automatically Set Data 🚀

3. Create Model Class with variables having same names as IDs of views in adapter view.

public class Model {

  // Declare data variables 
  String image;
  String name;

  public Model(String image, String name) {
    this.image = image;
    this.name = name;
  }

  // Getter & Setter for the variables
  public String getImage() {
    return image;
  }

  public void setImage(String image) {
    this.image = image;
  }

  public String getName() {
    return name;
  }

  public void setName(String name) {
    this.name = name;
  }

}

This example sets the value of name String in name TextView. image String URL is set to image ImageView. R.drawable.id format is also supported for ImageView. Make sure the variable name in Model and ID in layout.xml is same.

<?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:layout_width="match_parent"
  android:layout_height="wrap_content"
  android:orientation="vertical">

  <android.support.v7.widget.CardView
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  app:cardBackgroundColor="#fff"
  app:cardCornerRadius="16dp"
  app:cardElevation="4dp"
  app:cardPreventCornerOverlap="true"
  app:cardUseCompatPadding="true">

    <RelativeLayout
    android:layout_width="match_parent"
    android:id="@+id/relative"
    android:layout_height="wrap_content"
    android:gravity="center_vertical">

      <ImageView
      android:id="@+id/image"
      android:layout_width="100dp"
      android:layout_height="100dp"
      android:layout_margin="8dp"
      android:scaleType="centerCrop" />

      <TextView
      android:id="@+id/name"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:layout_margin="8dp"
      android:layout_toRightOf="@id/image"
      android:textColor="#000"
      android:textSize="18sp"/>

    </RelativeLayout>

  </android.support.v7.widget.CardView>

</LinearLayout>
