  .leftMargin(R.dimen.divider_left)

  .rightMargin(R.dimen.divider_right)

  .topMargin(R.dimen.divider_top)

  .bottomMargin(R.dimen.divider_bottom)

  .leftMarginFactory(new RecyclerViewDivider.MarginFactory() {

@Override

public int getMargin(int position) {

 return getResources().getDimensionPixelSize(R.dimen.divider_left);

}

  
}
)

  .rightMarginFactory(new RecyclerViewDivider.MarginFactory() {

@Override

public int getMargin(int position) {

 return getResources().getDimensionPixelSize(R.dimen.divider_right);

}

  
}
)

  .topMarginFactory(new RecyclerViewDivider.MarginFactory() {

@Override

public int getMargin(int position) {

 return getResources().getDimensionPixelSize(R.dimen.divider_top);

}

  
}
)

  .bottomMarginFactory(new RecyclerViewDivider.MarginFactory() {

@Override

public int getMargin(int position) {

 return getResources().getDimensionPixelSize(R.dimen.divider_bottom);

}

  
}
)

  .color(R.color.divider, R.dimen.divider_stroke_width)

  .drawable(R.drawable.divider)

  .drawableFactory(new RecyclerViewDivider.DrawableFactory() {

@Override

public Drawable getDrawable(int position) {

 return null;

}

 @Override

public int getStrokeWidth(int position) {

 return 0;

}

  
}
)

  .displayFilter(new RecyclerViewDivider.DisplayFilter() {

@Override

public boolean isDisplay(int position) {

 return false;

}

  
}
)

  .hideLastDivider()

  .build());
 

or


RecyclerViewDivider.builder(this).build().addTo(recyclerView);

DrawableFactory

When you are using a DrawableFactory, please be aware of this


  new RecyclerViewDivider.DrawableFactory() {

 @Override

 public Drawable getDrawable(int position) {

  /** 

  * When using ColorDrawable, don't forget to override {
@link getStrokeWidth()
}
. 

  * Because ColorDrawable.getIntrinsicWidth() always returns -1. 

  * So we need {
@link getStrokeWidth()
}
 to provider ColorDrawable's size 

  * For example: 

  * 

  * <pre><code> 

  *
new ColorDrawable(ContextCompat.getColor(MainActivity.this, R.color.divider));
 

  * </code></pre> 

  * 

  * or 

  * 

  * <pre><code> 

  *
<drawable name="divider">#303F9F</drawable> 

  * </code></pre> 

  */

  return null;

 
}

  @Override

 public int getStrokeWidth(int position) {

  /** 

  * No need to override, when using XML Drawable resource. 

  * Because in this case Drawable.getIntrinsicWidth() always returns it's size. 

  * So {
@link getStrokeWidth()
}
 is useless. 

  * For example: 

  * 

  * divider.xml drawable 

  * 

  * <pre><code> 

  *
<?xml version="1.0" encoding="utf-8"?> 

  *

 <shape xmlns:android="http://schemas.android.com/apk/res/android" 

  *

  android:shape="rectangle"> 

  *

  <size android:height="1dp" android:width="1dp"></size> 

  *

  <solid android:color="@color/divider"></solid> 

  *

 </shape> 

  * </code></pre> 

  */

  return 0;

 
}

This library is an extension for android buttons. You can add switchable buttons with cool animations when you press on them.

Neat 2D and 3D load indicators/spinners to use in your app. The library converts pre-made spritesheets to an AnimationDrawable to returns a Loader object than extends from ImageView. A very simple idea that can liven up your app.

Android Developer Icons is a custom icon set, included are:

  • 250 hand-crafted, pixel-perfect icons in 5 sizes and 14 colors
  • an icon font, made from the set
  • all sources: .svg, .ai, .eps, .eot, .ttf, .woff

Library containing common animations needed for transforming ViewPager scrolling on Android v13+. This library is a rewrite of the JazzyViewPager library and owes credit of the animation concepts directly to its source. The purpose of this rewrite is to provide an easier to use and extend implementation of ViewPager animations.

MatchView is a library which includes MatchTextView and MatchButton.

Renderers is an Android library created to avoid all the Adapter/ListView boilerplate needed to create a new adapter and all the spaghetti code that developers used to create following the ViewHolder classic implementation.

This Android library offers you two main classes to extend and create your own rendering algorithms out of your adapter implementation.

Renderers is an easy way to work with android ListView and Adapter classes. With this library you only have to create your renderers and declare the mapping between the object to render and the renderer.
