Of course, you can fix the width of the column. It also supports when the header is outside the recyclerView. 15 | 16 | ### Screenshots 17 | 18 | 19 | 20 | ### How to use 21 | 22 | For more details, please see the [bintray](https://bintray.com/beta/#/spoqa/maven/StickyScrollView?tab=overview). 23 | 24 | Add the following gradle dependency. 25 | 26 | ```groovy 27 | dependencies { 28 | implementation 'com.spoqa.stickyscrollview:StickyScrollView:1.0.1' 29 | } 30 | ``` 31 | 32 | ### Usage 33 | 34 | For more details, please see the [sample code](StickyScrollView/sample). 35 | 36 | #### Warning 37 | 38 | The sticky column must be a below format to work as intended. 😢 39 | 40 | ```xml 41 | 42 | 43 | 44 | 45 | ``` 46 | 47 | #### Usage 1 48 | 49 | The width of the sticky column is not adjusted as you scroll. 50 | 51 | ```xml 52 | 57 | 58 | 63 | 64 | 65 | ``` 66 | 67 | ```kotlin 68 | override fun onCreate(savedInstanceState: Bundle?) { 69 | ... 70 | main_scrollView.run { 71 | recyclerView = main_recyclerView 72 | } 73 | } 74 | ``` 75 | 76 | #### Usage 2 77 | 78 | The width of the sticky column is adjusted as you scroll. 79 | 80 | ```kotlin 81 | override fun onCreate(savedInstanceState: Bundle?) { 82 | ... 83 | main_scrollView.run { 84 | recyclerView = main_recyclerView 85 | minWidthOfStickyColumn = (100 * context.resources.displayMetrics.density).toInt() 86 | } 87 | } 88 | ``` 89 | 90 | #### Usage 3 91 | 92 | The header is outside the Recycleview. 93 | 94 | ```xml 95 | 100 | 101 | 105 | 106 | 110 | 111 | 116 | 117 | 121 | 122 | 123 | 124 | 128 | 129 | 130 | 131 | 132 | 133 | 138 | 139 | 140 | ``` 141 | 142 | ```kotlin 143 | override fun onCreate(savedInstanceState: Bundle?) { 144 | ... 145 | main_scrollView.run { 146 | stickyHeaderColumn = main_stickyHeaderColumnLayout 147 | recyclerView = main_recyclerView 148 | minWidthOfStickyColumn = (100 * context.resources.displayMetrics.density).toInt() 149 | } 150 | } 151 | ``` 152 | 153 | ## License 154 | 155 | For more details, please see the [LICENSE](StickyScrollView/LICENSE). 156 | 157 | ``` 158 | Copyright 2020 Spoqa 159 | Permission is hereby granted, free of charge, to any person obtaining a copy 160 | of this software and associated documentation files (the "Software"), to deal 161 | in the Software without restriction, including without limitation the rights 162 | to use, copy, modify, merge, publish, distribute, sublicense, and/or sell 163 | copies of the Software, and to permit persons to whom the Software is 164 | furnished to do so, subject to the following conditions: 165 | The above copyright notice and this permission notice shall be included in all 166 | copies or substantial portions of the Software. 167 | THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR 168 | IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, 169 | FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
