The easiest way to implement RecyclerView with just 1 LOC.
- Eliminate creation of big adapter classes & usage of
findViewById
for declaration of adapter views. - Get rid of different listeners and manage all view methods with single
SugarListener
. - Automatically put data from Model class to variable without any linking code.
- Forget about lengthy RecyclerView and make delicious
CandyView
.
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:1.2'
// add these for internal functioning
implementation 'com.squareup.picasso:picasso:{latest version}'
implementation 'com.android.support:recyclerview-v7:{build version}'
}
Add the code to create RecyclerView
using CandyView:
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);
}
}
Add SugarListener
for extended functionalities:
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 for particular position
if (position == 1)
textView.setTextColor(getResources().getColor(R.color.colorAccent));
}
}
Set data in views without any code:
Create Model Class
with data members having name same as ID 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;
}
}
Passing the above Model class and below adapter view automatically sets the value of name
(String) in name
(TextView). Not only this but image
(String URL) is set to image
(ImageView). R.drawable.id
format is also supported for ImageView. Make sure the variable name in Model class and id in Layout is same.
