Becomes visible when an attached target is scrolled up and invisible when scrolled down. 14 | 15 | ![Demo](art/demo.gif) 16 | 17 | ### Demo 18 | 19 | [![FloatingActionButton Demo on Google Play Store](http://developer.android.com/images/brand/en_generic_rgb_wo_60.png)](https://play.google.com/store/apps/details?id=com.melnykov.fab.sample) 20 | 21 | ### Integration 22 | 23 | **1)** Add as a dependency to your ``build.gradle``: 24 | 25 | ```groovy 26 | dependencies { 27 | compile 'com.melnykov:floatingactionbutton:1.3.0' 28 | } 29 | ``` 30 | 31 | **2)** Add the ``com.melnykov.fab.FloatingActionButton`` to your layout XML file. The button should be placed in the bottom right corner of the screen. The width and height of the floating action button are hardcoded to **56dp** for the normal and **40dp** for the mini button as specified in the [guidelines]. 32 | 33 | ```xml 34 | 38 | 39 | 43 | 44 | 54 | 55 | ``` 56 | 57 | **3)** Attach the FAB to ``AbsListView``, ``RecyclerView`` or ``ScrollView`` : 58 | 59 | ```java 60 | ListView listView = (ListView) findViewById(android.R.id.list); 61 | FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab); 62 | fab.attachToListView(listView); 63 | ``` 64 | 65 | Check the sample project to see how to use custom listeners if you need to track scroll events. 66 | 67 | **4)** Add the namespace ``xmlns:fab="http://schemas.android.com/apk/res-auto"`` to your layout file. 68 | 69 | + Set the button type (normal or mini) via the ``fab_type`` xml attribute (default is normal): 70 | 71 | ```xml 72 | fab:fab_type="mini" 73 | ``` 74 | or 75 | ```java 76 | fab.setType(FloatingActionButton.TYPE_MINI); 77 | ``` 78 | + Set the normal and pressed colors via the xml attributes: 79 | 80 | ```xml 81 | fab:fab_colorNormal="@color/primary" 82 | fab:fab_colorPressed="@color/primary_pressed" 83 | ``` 84 | or 85 | ```java 86 | fab.setColorNormal(getResources().getColor(R.color.primary)); 87 | fab.setColorPressed(getResources().getColor(R.color.primary_pressed)); 88 | ``` 89 | 90 | + Enable/disable the button shadow with the ``fab_shadow`` xml attribite (it's enabled by default): 91 | 92 | ```xml 93 | fab:fab_shadow="false" 94 | ``` 95 | or 96 | ```java 97 | fab.setShadow(false); 98 | ``` 99 | 100 | + Show/hide the button expliciltly: 101 | 102 | ```java 103 | fab.show(); 104 | fab.hide(); 105 | 106 | fab.show(false); // Show without an animation 107 | fab.hide(false); // Hide without an animation 108 | ``` 109 | 110 | + Specify the ripple color for API 21+: 111 | 112 | ```xml 113 | fab:fab_colorRipple="@color/ripple" 114 | ``` 115 | 116 | or 117 | ```java 118 | fab.setColorRipple(getResources().getColor(R.color.ripple)); 119 | ``` 120 | 121 | **5)** Set an icon for the ``FloatingActionButton`` using ``android:src`` xml attribute. Use drawables of size **24dp** as specified by [guidelines]. Icons of desired size can be generated with [Android Asset Studio]. 122 | 123 | ### Changelog 124 | 125 | **Version 1.3.0** 126 | + Add the disabled state for the FAB (thanks to [Aleksey Malevaniy](https://github.com/almozavr)); 127 | + Fix shadow assets. Rename shadow drawables with a prefix; 128 | + Generate default pressed and ripple colors (thanks to [Aidan Follestad](https://github.com/afollestad)). 129 | 130 | **Version 1.2.0** 131 | + Respect an elevation set manually for the FAB; 132 | + Don't emit a scroll when the listview is empty; 133 | + Add an ability to attach normal listeners for scroll operations (thanks to [Bill Donahue](https://github.com/bdonahue)). 134 | 135 | **Version 1.1.0:** 136 | + Do not ignore negative margins on pre-Lollipop; 137 | + Disable clicks on the FAB when it's hidden on pre-Honeycomb; 138 | + Some shadow tuning. 139 | 140 | **Version 1.0.9:** 141 | + Support API 7; 142 | + Fixed extra margins on pre-Lollipop devices; 143 | + Fixed mini FAB size; 144 | + Updated shadow assets to more accurately match 8dp elevation. 145 | 146 | **Version 1.0.8:** 147 | + ATTENTION! Breaking changes for custom listeners. Check an updated sample how to use them. 148 | + Added support for the ``ScrollView``; 149 | + Significantly optimized scroll detection for the ``RecyclerView``; 150 | + Fixed laggy animation for a list view with items of different height; 151 | + Added ``isVisible`` getter; 152 | + Deleted deprecated methods. 153 | 154 | **Version 1.0.7:** 155 | + Updated shadow assets to better match material design guidelines; 156 | + Make ``FabOnScrollListener`` and ``FabRecyclerOnViewScrollListener`` implement ``ScrollDirectionListener`` for easier custom listeners usage. 157 | 158 | **Version 1.0.6:** 159 | + Added support for the ``RecyclerView``; 160 | + Added ripple effect and elevation for API level 21. 161 | 162 | Thanks to [Aidan Follestad](https://github.com/afollestad). 163 | 164 | **Version 1.0.5:** 165 | + Updated shadow to more accurately match the material design spec; 166 | 167 | **Version 1.0.4:** 168 | 169 | + Allow a custom ``OnScrollListeners`` to be attached to a list view; 170 | + Work properly with list of different height rows; 171 | + Ignore tiny shakes of fingers. 172 | 173 | **Version 1.0.3:** 174 | + Add methods to show/hide without animation; 175 | + Fix show/hide when a view is not measured yet. 176 | 177 | 178 | ### Applications using FloatingActionButton 179 | 180 | Please [ping](mailto:makovkastar@gmail.com) me or send a pull request if you would like to be added here. 181 | 182 | Icon | Application | Icon | Application 183 | ------------ | ------------- | ------------- | ------------- 184 | | [Finger Gesture Launcher] | | [Vocabletrainer] 185 | | [Lanekeep GPS Mileage Tracker] | | [Score It] 186 | | [Перезвони мне] | | [App Swap] 187 | | [QKSMS - Quick Text Messenger] | | [Uninstaller - Beta Version] 188 | | [Device Control] | | [Confide] 189 | | [Date Night] | | [Jair Player The Music Rainbow] 190 | | [Taskr - Lista de Tareas] | | [Festivos: ¡Conoce el mundo!] 191 | | [nowPaper] | | [Vicious chain - Don't do that!] 192 | | [My Football Stats] | | [The ScoreBoard] 193 | | [NavPoint] | | [Just Reminder] 194 | | [Early Notes] | | [Ranch - Smart Tip Calculator] 195 | | [Thiengo Calopsita] | | [Tinycore - CPU, RAM monitor] | 196 | | [Battery Aid Saver & Manager] | | [GameRaven] 197 | | [Polaris Office] | | [Call Utils] 198 | | [Colorful Note] | | [CallSticker - заметки звонка] 199 | 200 | ### Links 201 | 202 | Country flag icons used in the sample are taken from www.icondrawer.com 203 | 204 | ### License 205 | 206 | ``` 207 | The MIT License (MIT) 208 | 209 | Copyright (c) 2014 Oleksandr Melnykov 210 | 211 | Permission is hereby granted, free of charge, to any person obtaining a copy 212 | of this software and associated documentation files (the "Software"), to deal 213 | in the Software without restriction, including without limitation the rights 214 | to use, copy, modify, merge, publish, distribute, sublicense, and/or sell 215 | copies of the Software, and to permit persons to whom the Software is 216 | furnished to do so, subject to the following conditions: 217 | 218 | The above copyright notice and this permission notice shall be included in all 219 | copies or substantial portions of the Software. 220 | 221 | THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR 222 | IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, 223 | FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
