1 | # MultiImageView
2 | 多图加载，适用于与RecyclerView结合使用，用于博客卡片图文加载
3 |
4 | # How to
5 |
6 | To get a Git project into your build:
7 |
8 | **Step 1**. Add the JitPack repository to your build file
9 |
10 | Add it in your root build.gradle at the end of repositories:
11 |
12 | ```gradle
13 | allprojects {
14 | repositories {
15 | ...
16 | maven { url 'https://jitpack.io' }
17 | }
18 | }
19 | ```
20 |
21 | **Step 2**. Add the dependency
22 | ```gradle
23 | dependencies {
24 | implementation 'com.github.ydslib:MultiImageView:1.0.4'
25 | }
26 | ```
27 |
28 | Share this release:
29 |
30 | Tweet
31 |
32 | Link
33 | That's it! The first time you request a project JitPack checks out the code, builds it and serves the build artifacts (jar, aar).
34 |
35 | If the project doesn't have any GitHub Releases you can use the short commit hash or 'master-SNAPSHOT' as the version.
36 |
37 | # Use
38 | use in xml file
39 | ```xml
40 |
47 | ```
48 | use in java file
49 | ```java
50 | // local image
51 | private int[] src = new int[]{
52 | R.drawable.test01,R.drawable.test02,R.drawable.test03,
53 | R.drawable.test04,R.drawable.test05,R.drawable.test06,
54 | R.drawable.test07,R.drawable.test08,R.drawable.test09,R.drawable.test10
55 | };
56 | for(int i=0;i mList = new ArrayList<>();
65 | mList.add("https://flmfxz.com/2020/04/MFStar范模学院Vol275糯美子Mini-9.jpg")
66 | ...
67 |
68 | mMultiImageView.setImagesData(mList);
69 |
70 | //加载图片与MultiImageView控件分离，这样如果想用Glide加载，
71 | //则实现IMultiImageLoader接口就行了，具体实例可见simple
72 | mMultiImageView.setMultiImageLoader(new GlideLoadImage());
73 |
74 |
75 | ```
76 | # Attribute
77 |
78 | - app:imgGap="3dp"
79 | The image gap
80 |

82 | This attribute is used to control whether the prompt text is displayed
83 |
84 | - app:scaleType="center"
85 | This attribute is used to control how the picture is displayed
86 |
87 | - app:maxSize="2"
88 | The max number of image should be show
