Add the widget to your layout file, e.g.: 37 | ```xml 38 | 41 | 42 | 45 | 46 | 50 | 51 | 52 | ``` 53 | 54 | 2. Attach the `RecyclerFastScroller` to your `RecyclerView`: 55 | ```java 56 | fastScroller.attachRecyclerView(recyclerView); 57 | ``` 58 | If the adapter hasn't been set when you attach the fast scroller, call `attachAdapter()` afterwords. 59 | 60 | See the sample project for demos. 61 | 62 | ### AppBarLayout support 63 | Use `attachAppBarLayout(coordinatorLayout, appBarLayout)`. See the sample project for the demo. 64 | 65 | ### Customization 66 | | Method | Attribute | Description | 67 | | --- | --- | --- | 68 | | `setBarColor(int color)`| `rfs_barColor` | Color of scrollbar. Defaults to `colorControlNormal` attribute. Alpha of ~22% is applied to the drawable to match stock `ListView` fast scroller. | 69 | | `setHandleNormalColor(int color)` | `rfs_handleNormalColor` | Color of handle. Defaults to `colorControlNormal` attribute. | 70 | | `setHandlePressedColor(int color)` | `rfs_handlePressedColor` | Color of pressed handle. Defaults to `colorAccent` attribute. | 71 | | `setTouchTargetWidth(int width)` | `rfs_touchTargetWidth` | Width of the touch target. Defaults to 24dp (while the Android docs recommend at least 48dp, 24dp is more practical considering it will block touch in the right of the `RecyclerView`). | 72 | | `setHideDelay(int milliseconds)` | `rfs_hideDelay` | Hide delay in milliseconds. Defaults to 1500ms. | 73 | | `setHidingEnabled(boolean enabled)` | `rfs_hidingEnabled` | Whether scrollbar is hidden after delay. Defaults to true. | 74 | | `setOnHandleTouchListener(OnTouchListener listener)` | -- | Sets listener for handle touch events. | 75 | 76 | Corresponding getters are also available. 77 | 78 | ####Attribute Usage 79 | ```xml 80 | 83 | ``` 84 | 85 | 86 | ### License 87 | ``` 88 | Copyright 2016 Daniel Ciao 89 | 90 | Licensed under the Apache License, Version 2.0 (the "License"); 91 | you may not use this file except in compliance with the License. 92 | You may obtain a copy of the License at 93 | 94 | http://www.apache.org/licenses/LICENSE-2.0 95 | 96 | Unless required by applicable law or agreed to in writing, software 97 | distributed under the License is distributed on an "AS IS" BASIS, 98 | WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. 99 | See the License for the specific language governing permissions and 100 | limitations under the License. 101 | ``` 102 | -------------------------------------------------------------------------------- /art/small.gif: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/pluscubed/recycler-fast-scroll/3de76812553a77bfd25d3aea0a0af4d96516c3e3/art/small.gif -------------------------------------------------------------------------------- /build.gradle: -------------------------------------------------------------------------------- 1 | // Top-level build file where you can add configuration options common to all sub-projects/modules. 2 | 3 | buildscript { 4 | repositories { 5 | google() 6 | jcenter() 7 | } 8 | dependencies { 9 | classpath 'com.android.tools.build:gradle:3.4.1' 10 | classpath 'com.github.dcendents:android-maven-gradle-plugin:2.1' 11 | classpath 'com.github.ben-manes:gradle-versions-plugin:0.21.0' 12 | 13 | // NOTE: Do not place your application dependencies here; they belong 14 | // in the individual module build.gradle files 15 | } 16 | } 17 | 18 | allprojects { 19 | repositories { 20 | google() 21 | jcenter() 22 | } 23 | } 24 | 25 | task updateWrapper(type: Wrapper) { 26 | gradleVersion = '5.4.1' 27 | distributionType = Wrapper.DistributionType.ALL 28 | } 29 | 30 | 31 | task clean(type: Delete) { 32 | delete rootProject.buildDir 33 | } 34 | 35 | apply plugin: 'com.github.ben-manes.versions' 36 | -------------------------------------------------------------------------------- /gradle.properties: -------------------------------------------------------------------------------- 1 | # Project-wide Gradle settings. 2 | 3 | # IDE (e.g. Android Studio) users: 4 | # Gradle settings configured through the IDE *will override* 5 | # any settings specified in this file. 6 | 7 | # For more details on how to configure your build environment visit 8 | # http://www.gradle.org/docs/current/userguide/build_environment.html 9 | 10 | # Specifies the JVM arguments used for the daemon process. 11 | # The setting is particularly useful for tweaking memory settings. 12 | # Default value: -Xmx10248m -XX:MaxPermSize=256m 13 | # org.gradle.jvmargs=-Xmx2048m -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8 14 | 15 | # When configured, Gradle will run in incubating parallel mode. 16 | # This option should only be used with decoupled projects.
