Uses a different mechanism than similar libraries to provide smooth movement of scroller handle when scrolling the list. Can be used with vertical and horizontal RecyclerViews. 3 | 4 | This library is still in early development stage. PRs are welcome. 5 | 6 | ![alt tag](http://i.imgur.com/EQsZ01x.gif) 7 | 8 | ## Usage 9 | -------- 10 | In your layout file: 11 | ```java 12 | 15 | 16 | 21 | 22 | 28 | 29 | 30 | ``` 31 | 32 | In Activity/Fragment: 33 | 34 | ```java 35 | recyclerView = (RecyclerView) findViewById(R.id.recyclerview); 36 | fastScroller = (FastScroller) findViewById(R.id.fastscroll); 37 | recyclerView.setLayoutManager(new LinearLayoutManager(this)); 38 | recyclerView.setAdapter(adapter); 39 | 40 | //has to be called AFTER RecyclerView.setAdapter() 41 | fastScroller.setRecyclerView(recyclerView); 42 | ``` 43 | 44 | ### Horizontal orientation 45 | 46 | You can use this library with horizontal LayoutManager. To do it use android:orientation="horizontal" attribute: 47 | 48 | ```java 49 | 50 | 55 | 56 | ``` 57 | 58 | ## Download 59 | -------- 60 | 61 | Download via Gradle: 62 | ```groovy 63 | compile 'com.futuremind.recyclerfastscroll:fastscroll:0.1.4' 64 | ``` 65 | 66 | ## License 67 | ------- 68 | 69 | Copyright 2015 Future Mind 70 | 71 | Licensed under the Apache License, Version 2.0 (the "License"); 72 | you may not use this file except in compliance with the License. 73 | You may obtain a copy of the License at 74 | 75 | http://www.apache.org/licenses/LICENSE-2.0 76 | 77 | Unless required by applicable law or agreed to in writing, software 78 | distributed under the License is distributed on an "AS IS" BASIS, 79 | WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. 80 | See the License for the specific language governing permissions and 81 | limitations under the License. 82 | -------------------------------------------------------------------------------- /fastscroll/build.gradle: -------------------------------------------------------------------------------- 1 | apply plugin: 'com.android.library' 2 | apply plugin: 'com.jfrog.bintray' 3 | apply plugin: 'com.github.dcendents.android-maven' 4 | 5 | android { 6 | compileSdkVersion rootProject.compileSdkVersion 7 | buildToolsVersion rootProject.buildToolsVersion 8 | 9 | resourcePrefix "fastscroll__" 10 | 11 | defaultConfig { 12 | minSdkVersion rootProject.minSdkVersion 13 | targetSdkVersion rootProject.targetSdkVersion 14 | versionCode rootProject.versionCode 15 | versionName rootProject.versionName 16 | } 17 | buildTypes { 18 | release { 19 | minifyEnabled false 20 | proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 21 | } 22 | } 23 | } 24 | 25 | ext { 26 | bintrayRepo = 'maven' 27 | bintrayName = 'recycler-fast-scroll' 28 | 29 | publishedGroupId = 'com.futuremind.recyclerfastscroll' 30 | libraryName = 'Recycler Fast Scroll' 31 | artifact = 'fastscroll' 32 | 33 | libraryDescription = 'Provides fast scroll and section indexer for recycler view.' 34 | 35 | siteUrl = 'https://github.com/FutureMind/recycler-fast-scroll' 36 | gitUrl = 'https://github.com/FutureMind/recycler-fast-scroll.git' 37 | 38 | libraryVersion = rootProject.versionName 39 | 40 | developerId = 'mklimczak' 41 | developerName = 'Michal Klimczak' 42 | developerEmail = 'm.klimczak@futuremind.com' 43 | 44 | licenseName = 'The Apache Software License, Version 2.0' 45 | licenseUrl = 'http://www.apache.org/licenses/LICENSE-2.0.txt' 46 | allLicenses = ["Apache-2.0"] 47 | } 48 | 49 | group = publishedGroupId 50 | 51 | install { 52 | repositories.mavenInstaller { 53 | // This generates POM.xml with proper parameters 54 | pom { 55 | project { 56 | packaging 'aar' 57 | groupId publishedGroupId 58 | artifactId artifact 59 | 60 | // Add your description here 61 | name libraryName 62 | description libraryDescription 63 | url siteUrl 64 | 65 | // Set your license 66 | licenses { 67 | license { 68 | name licenseName 69 | url licenseUrl 70 | } 71 | } 72 | developers { 73 | developer { 74 | id developerId 75 | name developerName 76 | email developerEmail 77 | } 78 | } 79 | scm { 80 | connection gitUrl 81 | developerConnection gitUrl 82 | url siteUrl 83 | 84 | } 85 | } 86 | } 87 | } 88 | } 89 | 90 | version = libraryVersion 91 | 92 | task sourcesJar(type: Jar) { 93 | from android.sourceSets.main.java.srcDirs 94 | classifier = 'sources' 95 | } 96 | 97 | task javadoc(type: Javadoc) { 98 | source = android.sourceSets.main.java.srcDirs 99 | classpath += project.files(android.getBootClasspath().join(File.pathSeparator)) 100 | } 101 | 102 | task javadocJar(type: Jar, dependsOn: javadoc) { 103 | classifier = 'javadoc' 104 | from javadoc.destinationDir 105 | } 106 | artifacts { 107 | archives javadocJar 108 | archives sourcesJar 109 | } 110 | 111 | // Bintray 112 | Properties properties = new Properties() 113 | properties.load(project.rootProject.file('local.properties').newDataInputStream()) 114 | 115 | bintray { 116 | user = properties.getProperty("bintray.user") 117 | key = properties.getProperty("bintray.apikey") 118 | 119 | configurations = ['archives'] 120 | pkg { 121 | repo = bintrayRepo 122 | name = bintrayName 123 | desc = libraryDescription 124 | websiteUrl = siteUrl 125 | vcsUrl = gitUrl 126 | licenses = allLicenses 127 | publish = true 128 | publicDownloadNumbers = true 129 | version { 130 | desc = libraryDescription 131 | gpg { 132 | sign = true //Determines whether to GPG sign the files.
