7 |
8 | ## Demo app
9 | To run the demo project, clone the repository and run it via Android Studio.
10 | (OR)
11 | Download the latest demo apk from [releases](https://github.com/Chrisvin/BlobBackgroundLayout/releases).
12 |
13 | ## Usage
14 | #### Set up the dependency
15 | 1. Add the JitPack repository to your root build.gradle at the end of repositories:
16 | ```
17 | allprojects {
18 | repositories {
19 | ...
20 | maven { url 'https://jitpack.io' }
21 | }
22 | }
23 | ```
24 | 2. Add the BlobBackgroundLayout dependency in the build.gradle:
25 | ```
26 | implementation 'com.github.Chrisvin:BlobBackgroundLayout:1.1'
27 | ```
28 |
29 | #### Use a `BlobLayout` as the base container in your activity/fragments.
30 | ```
31 |
32 |
40 |
41 |
42 |
43 |
44 |
45 |
46 | ```
47 |
48 | #### Add blobs in the `BlobLayout` using `addBlob()`
49 | The individual blobs can be customized in `Blob.Configuration`.
50 | ```
51 | blobLayout.addBlob(
52 | Blob.Configuration(
53 | // Position of the Blobs center point
54 | blobCenterPosition = newBlobCenterPosition, // Optional, Default = PointF(0f, 0f)
55 |
56 | // The number of curve points in the blob
57 | pointCount = newPointCount, // Optional, Default = 16
58 |
59 | // The radius of the blob
60 | radius = newRadius, // Optional, Default = 750f
61 |
62 | // The maximum offset from the radius of the blob
63 | maxOffset = newMaxOffset, // Optional, Default = 100f
64 |
65 | // Should the blob animate/change shape over time
66 | shouldAnimateShape = newShouldAnimateShape, // Optional, Default = true
67 |
68 | // Time taken for blob to fully change from one shape to another
69 | shapeAnimationDuration = newShapeAnimationDuration, // Optional, Default = 2000L
70 |
71 | // The interpolator used for shape animation
72 | shapeAnimationInterpolator = newShapeAnimationInterpolator, // Optional, Default = LinearInterpolator()
73 |
74 | // The paint used to draw the blob, can be used to set color, draw only outline, etc.
75 | paint = newPaint
76 | /* Optional, Default = Paint().apply {
77 | isAntiAlias = true
78 | style = Paint.Style.FILL
79 | color = Color.RED
80 | }
81 | */
82 | )
83 | )
84 | ```
85 |
86 | ### And you're done with your awesome blobby UI, easy-peasy. ^_^
87 |
88 | ## Additional functionalities
89 | #### Get blob count
90 | ```
91 | val blobCount: Int = blobLayout.getBlobCount()
92 | ```
93 | #### Recreate all blobs with new shapes
94 | ```
95 | blobLayout.recreateBlobs()
96 | ```
97 | #### Recreate blob at index with new shape
98 | ```
99 | blobLayout.recreateBlob(index)
100 | ```
101 | #### Remove all blobs
102 | ```
103 | blobLayout.removeBlobs()
104 | ```
105 | #### Remove blob at index
106 | ```
107 | blobLayout.removeBlob(index)
108 | ```
109 | #### Get all blob configurations
110 | ```
111 | val blobConfigs: Array = blobLayout.getBlobConfigurations()
112 | ```
113 | #### Get configuration for blob at index
114 | ```
115 | val blobConfig: Blob.Configuration = blobLayout.getBlobConfiguration(index)
116 | ```
117 | #### Update all blob configurations
118 | ```
119 | blobLayout.updateBlobConfigurations(blobConfigs)
120 | ```
121 | #### Update configuration for blob at index
122 | ```
123 | blobLayout.updateBlobConfiguration(blobConfig, index)
124 | ```
125 |
126 | Note: Aforementioned functionalities are supported in all BlobLayouts (`BlobConstraintLayout`,`BlobFrameLayout`,`BlobLinearLayout`)
127 |
