It shows an initial 6 | album (buckets) chooser and then images in selected album. Can limit the number of images that 7 | can be selected. Can be used in apps with APK 11 onwards. 8 | 9 | Sample app can be found [here](https://github.com/darsh2/MultipleImageSelect/tree/master/sample) 10 | #Usage 11 | Include this library in your project using gradle (thanks to [JitPack.io](https://github.com/jitpack-io)). 12 | 13 | For stable build: 14 | ```gradle 15 | repositories { 16 | maven { 17 | url "https://jitpack.io" 18 | } 19 | } 20 | 21 | dependencies { 22 | compile 'com.github.darsh2:MultipleImageSelect:v0.0.4' 23 | } 24 | ``` 25 | 26 | For using the latest build, replace the tag in dependencies above with latest commit hash. Example: 27 | ```gradle 28 | repositories { 29 | maven { 30 | url "https://jitpack.io" 31 | } 32 | } 33 | 34 | dependencies { 35 | compile 'com.github.darsh2:MultipleImageSelect:3474549' 36 | } 37 | ``` 38 | 39 | In project's AndroidManifest.xml, add the following under application node: 40 | ```xml 41 | 44 | 45 | 46 | 47 | 48 | ``` 49 | In the activity from where you want to call image selector, create Intent as follows: 50 | ```java 51 | Intent intent = new Intent(this, AlbumSelectActivity.class); 52 | //set limit on number of images that can be selected, default is 10 53 | intent.putExtra(Constants.INTENT_EXTRA_LIMIT, numberOfImagesToSelect); 54 | startActivityForResult(intent, Constants.REQUEST_CODE); 55 | ``` 56 | and override onActivityResult as follows: 57 | ```java 58 | @Override 59 | protected void onActivityResult(int requestCode, int resultCode, Intent data) { 60 | if (requestCode == Constants.REQUEST_CODE && resultCode == RESULT_OK && data != null) { 61 | //The array list has the image paths of the selected images 62 | ArrayList images = data.getParcelableArrayListExtra(Constants.INTENT_EXTRA_IMAGES); 63 | ... 64 | } 65 | ``` 66 | #Custom Styles 67 | ![Alt text](/screenshots/misCC.gif) 68 | 69 | 1. To change the color of UI elements, in colors.xml file, override the following attributes with the desired colors. Example: 70 | 71 | ```xml 72 | #673AB7 73 | #512DA8 74 | #D1C4E9 75 | #536DFE 76 | #212121 77 | #727272 78 | #B6B6B6 79 | #FFFFFF 80 | #99FFFFFF 81 | #000000 82 | ``` 83 | 84 | ![Alt text](/screenshots/misCT.gif) 85 | 86 | 2. To change the theme altogether, do step 1, and make the following changes in styles.xml and manifest file: 87 | 88 | styles.xml: 89 | Create the theme you want to use along with a theme for toolbar and actionmode. Example: 90 | 91 | ```xml 92 | 99 | 102 | 104 | ``` 105 | 106 | AndroidManifest.xml: 107 | Add ```tools:replace="android:theme"``` to AlbumSelectActivity and ImageSelectActivity and specify theme to use. Example: 108 | 109 | ```xml 110 | 113 | 114 | 117 | 118 | 119 | 120 | 121 | 124 | 125 | 126 | 127 | 128 | ``` 129 | #Screenshots 130 | Can be found [here](https://github.com/darsh2/MultipleImageSelect/tree/master/screenshots) 131 | #Apps using this 132 | [Gallery Organizer](https://play.google.com/store/apps/details?id=com.darsh.galleryorganizer2) 133 | 134 | [PictureJam Collage Maker](https://play.google.com/store/apps/details?id=xyz.pichancer.picturejam.free) 135 | #Similar Projects 136 | Similar libraries can be found [here](https://android-arsenal.com/tag/157) 137 | #Acknowledgements 138 | This library makes use of [Glide](https://github.com/bumptech/glide) by Bump Technologies. 139 | (Thanks to [WindSekirun](https://github.com/WindSekirun) for suggesting Glide) 140 | #License 141 | ```license 142 | Copyright 2015 Darshan Dorai 143 | 144 | Licensed under the Apache License, Version 2.0 (the "License"); 145 | you may not use this file except in compliance with the License. 146 | You may obtain a copy of the License at 147 | 148 | http://www.apache.org/licenses/LICENSE-2.0 149 | 150 | Unless required by applicable law or agreed to in writing, software 151 | distributed under the License is distributed on an "AS IS" BASIS, 152 | WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. 153 | See the License for the specific language governing permissions and 154 | limitations under the License. 155 | ``` 156 | -------------------------------------------------------------------------------- /sample/sample.iml: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | 5 | 6 | 8 | 9 | 10 | 11 | 24 | 25 | 26 | 27 | 28 | 29 | 30 | 31 | 32 | 33 | 34 | 35 | 36 | 37 | 38 | 39 | 40 | 41 | 42 | 43 | 44 | 45 | 46 | 47 | 48 | 49 | 50 | 51 | 52 | 53 | 54 | 55 | 56 | 57 | 58 | 59 | 60 | 61 | 62 | 63 | 64 | 65 | 66 | 67 | 68 | 69 | 70 | 71 | 72 | 73 | 74 | 75 | 76 | 77 | 78 | 79 | 80 | 81 | 82 | 83 | 84 | 85 | 86 | 87 | 88 | 89 | 90 | 91 | 92 | 93 | 94 | 95 | 96 | 97 | 98 | 99 | 100 | 101 | 102 | 103 | 104 | 105 | 106 | 107 | 108 | 109 | 110 | 111 | 112 | 113 | 114 | 115 | 116 | 117 | 118 | 119 | 120 | 121 | 122 | 123 | 124 | 125 | 126 | -------------------------------------------------------------------------------- /multipleimageselect/multipleimageselect.iml: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | 5 | 6 | 8 | 9 | 10 | 11 | 25 | 26 | 27 | 28 | 29 | 30 | 31 | 32 | 33 | 34 | 35 | 36 | 37 | 38 | 39 | 40 | 41 | 42 | 43 | 44 | 45 | 46 | 47 | 48 | 49 | 50 | 51 | 52 | 53 | 54 | 55 | 56 | 57 | 58 | 59 | 60 | 61 | 62 | 63 | 64 | 65 | 66 | 67 | 68 | 69 | 70 | 71 | 72 | 73 | 74 | 75 | 76 | 77 | 78 | 79 | 80 | 81 | 82 | 83 | 84 | 85 | 86 | 87 | 88 | 89 | 90 | 91 | 92 | 93 | 94 | 95 | 96 | 97 | 98 | 99 | 100 | 101 | 102 | 103 | 104 | 105 | 106 | 107 | 108 | 109 | 110 | 111 | 112 | 113 | 114 | 115 | 116 | 117 | 118 | 119 | 120 | 121 | 122 | 123 | 124 | 125 | 126 | 127 | 128 | 129 | -------------------------------------------------------------------------------- /LICENSE.txt: -------------------------------------------------------------------------------- 1 | Apache License 2 | Version 2.0, January 2004 3 | http://www.apache.org/licenses/ 4 | 5 | TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION 6 | 7 | 1.
