Step 1. Add the JitPack repository to your build file

Add it in your root settings.gradle at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url 'https://jitpack.io' }
		}
	}

Add it in your settings.gradle.kts at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url = uri("https://jitpack.io") }
		}
	}

Add to pom.xml

	<repositories>
		<repository>
		    <id>jitpack.io</id>
		    <url>https://jitpack.io</url>
		</repository>
	</repositories>

Add it in your build.sbt at the end of resolvers:

 
    resolvers += "jitpack" at "https://jitpack.io"

Add it in your project.clj at the end of repositories:

 
    :repositories [["jitpack" "https://jitpack.io"]]

Step 2. Add the dependency

	dependencies {
		implementation 'com.github.downtail:itemdecorationplus:0.2.0'
	}

	dependencies {
		implementation("com.github.downtail:itemdecorationplus:0.2.0")
	}

	<dependency>
	    <groupId>com.github.downtail</groupId>
	    <artifactId>itemdecorationplus</artifactId>
	    <version>0.2.0</version>
	</dependency>


                            
    libraryDependencies += "com.github.downtail" % "itemdecorationplus" % "0.2.0"


                            
    :dependencies [[com.github.downtail/itemdecorationplus "0.2.0"]]

ItemDecorationPlus

介绍

在工作中多次遇到需要为RecyclerView设置悬浮或者说粘性的头部，于是有了这个东西。有一点非常重要的是，如果搭配 BaseRecyclerViewAdapterHelper 可以实现更加丰富的效果，比如类似QQ好友列表的分组悬浮以及其他一些需求。

效果预览

普通item悬浮

树形

混合item

使用方式

添加jitpack仓库


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

添加依赖


implementation 'com.github.downtail:ItemDecorationPlus:0.2.0'

实现接口(让adapter来实现)


public class MaskedAdapter extends RecyclerView.Adapter<MaskedAdapter.SampleHolder> implements FloaterExtension{}


public interface FloaterExtension {

    //是否悬浮
    boolean isFloaterView(int position);

    //悬浮的itemType
    @IntRange(from = 0, to = Integer.MAX_VALUE)
    int getItemType(int position);
}

为RecyclerView添加ItemDecoration


FloaterView floaterView = FloaterView.init(rvExhibition)
                .addItemType(ExhibitionMultipleEntity.ITEM_HEADER,R.layout.item_basket_exhibition_header)
                .setOnBindViewListener(new FloaterView.OnBindViewListener() {
                    @Override
                    public void onBind(View view, int position) {
                        
                    }
                })
                .setOnItemChildClickListener(new FloaterView.OnItemChildClickListener() {
                    @Override
                    public void onItemChildClick(View view, int position) {
                        
                    }
                });
        FloaterItemDecoration floaterItemDecoration = new FloaterItemDecoration(exhibitionMultipleAdapter, floaterView);
