7 | Simple usage
8 | Styled view
9 | Rotation support
10 | Custom objects
11 |
12 | Traditional viewer without any customizing. The fastest way to implement.
13 | Customized viewer with overlay view, custom margins and padding.
14 | Example of how to handle activity rotation.
15 | Using formatter for custom objects - forget about converting.
16 | View
17 |
18 | Share
19 | Tap on any image to open viewer!
20 | Open options menu in toolbar to check available options to change!
21 | Dialog was successfully dismissed!
22 | Open the viewer and try to rotate device. Important! Don\'t forget to enable rotation settings :)
23 | This example uses custom image objects and shows images via custom formatter.
24 | Got it!
25 | Options
26 |
27 |
28 | - hide status bar
29 | - images margin
30 | - container padding
31 | - images rounding
32 | - swipe-to-dismiss
33 | - zooming
34 | - show overlay
35 | - random background
36 | - post-processing (via ImageRequestBuilder)

10 | ### Who we are
11 | Need iOS and Android apps, MVP development or prototyping? Contact us via info@stfalcon.com. We develop software since 2009, and we're known experts in this field. Check out our [portfolio](https://stfalcon.com/en/portfolio) and see more libraries from [stfalcon-studio](https://stfalcon-studio.github.io/).
12 |
13 | ## Requirements
14 |
15 | * Fresco v.0.12.0 and higher
16 | * SDK 14 and and higher
17 |
18 | ## Demo Application
19 |
20 | [](https://play.google.com/store/apps/details?id=com.stfalcon.frescoimageviewersample)
21 |
22 | ## Usage
23 |
24 | #### Simple usage
25 | All you need to show a viewer is pass the context, start position and List or String[] into builder and call `show()`.
26 | ```java
27 | new ImageViewer.Builder(context, list)
28 | .setStartPosition(startPosition)
29 | .show();
30 | ```
31 |
32 | #### Custom objects
33 | But what if in your application images are represented not only with urls? For example, you have object with url and description? You'll have to convert it to list of Strings and only then pass it to viewer, right?
34 | No, it's unnecessary! With `ImageViewer.Formatter` you can pass list of your custom images to viewer and simply write a rule for url extracting:
35 | ```java
36 | List images = getImages();
37 | new ImageViewer.Builder<>(this, images)
38 | .setFormatter(new ImageViewer.Formatter() {
39 | @Override
40 | public String format(CustomImage customImage) {
41 | return customImage.getUrl();
42 | }
43 | })
44 | .show();
45 | ```
46 | If formatter isn't passed, `Object.toString()` will be used for image formatting as default behavior.
47 |
48 | Piece of cake! :cake: :wink:
49 |
50 | ## Reminder
51 | Don't forget to initialize Fresco in your Application class:
52 | ```java
53 | Fresco.initialize(this);
54 | ```
55 |
56 | And if you expect to open really large images, use configuration below for better performance:
57 | ```java
58 | ImagePipelineConfig config = ImagePipelineConfig.newBuilder(this)
59 | .setProgressiveJpegConfig(new SimpleProgressiveJpegConfig())
60 | .setResizeAndRotateEnabledForNetwork(true)
61 | .setDownsampleEnabled(true)
62 | .build();
63 | Fresco.initialize(this, config);
64 | ```
65 |
66 | ## Customizing
67 |
68 | You can also customize a viewer to fit your needs.
69 |
70 | #### Background
71 | Use `setBackgroundColorRes(colorRes)` or `setBackgroundColor(colorInt)` to set color for fading background.
72 |
73 | #### Custom overlay view
74 | If you need some content over the image (e.g. sharing or download button, description, numeration etc.) you can set your custom view using `setOverlayView(customView)` and bind it with viewer through `ImageViewer.OnImageChangeListener`.
75 |
76 | #### Custom drawee hierarchy
77 | Of course, according to Fresco flexibility, you can use your custom GenericDraweeHierarchy.
78 | To do this you simply need to create GenericDraweeHierarchy**Builder** and pass it into builder:
79 | ```java
80 | GenericDraweeHierarchyBuilder hierarchyBuilder = GenericDraweeHierarchyBuilder.newInstance(getResources())
81 | .setFailureImage(R.drawable.failureDrawable)
82 | .setProgressBarImage(R.drawable.progressBarDrawable)
83 | .setPlaceholderImage(R.drawable.placeholderDrawable);
84 |
85 | builder.setCustomDraweeHierarchyBuilder(hierarchyBuilder)
86 | ```
87 |
88 | :exclamation:**But there is a limitation**: default ScaleType in hierarchy is `ScaleType.FIT_CENTER`, so custom value will be ignored
89 |
90 | #### Custom image requests
91 | For rare cases like post-processing or bitmap resizing you need to use your custom ImageRequestBuilder.
92 | Create it with `ImageViewer.createImageRequestBuilder()` and after configuration pass it to viewer through `setCustomImageRequestBuilder(ImageRequestBuilder)`.
93 | ```java
94 | builder.setCustomImageRequestBuilder(
95 | ImageViewer.createImageRequestBuilder()
96 | .setPostprocessor(new GrayscalePostprocessor()));
97 | ```
98 |
99 | #### Image margin
100 | Simply add margins between images with dimens with setImageMargin(context, dimen) or in `px` using `setImageMarginPx(marginPx)`.
101 |
102 | #### Container padding
103 | Overlay image hides part of image? Set container padding with dimens using `setContainerPadding(context, start, top, end, bottom)` or `setContainerPadding(context, dimean)` for all sides at once.
104 | For setting padding in pixels, just use `setContainerPaddingPx(...)` method.
105 |
106 | #### Status bar visibility
107 | To show/hide status bar in view property you can set `hideStatusBar(boolean)` in builder. The default value is `true`.
108 |
109 | #### Gestures disabling
110 | If you need to disable some of gestures - do it using `allowSwipeToDismiss(boolean)` and `allowZooming(boolean)` accordingly.
111 |
112 | Here is an example that sets all the possible options:
113 |
114 | ```java
115 | new ImageViewer.Builder<>(this, images)
116 | .setStartPosition(startPosition)
117 | .hideStatusBar(false)
118 | .allowZooming(true)
119 | .allowSwipeToDismiss(true)
120 | .setBackgroundColorRes(colorRes)
121 | //.setBackgroundColor(color)
122 | .setImageMargin(margin)
123 | //.setImageMarginPx(marginPx)
124 | .setContainerPadding(this, dimen)
125 | //.setContainerPadding(this, dimenStart, dimenTop, dimenEnd, dimenBottom)
126 | //.setContainerPaddingPx(padding)
127 | //.setContainerPaddingPx(start, top, end, bottom)
128 | .setCustomImageRequestBuilder(imageRequestBuilder)
129 | .setCustomDraweeHierarchyBuilder(draweeHierarchyBuilder)
130 | .setImageChangeListener(imageChangeListener)
131 | .setOnDismissListener(onDismissListener)
132 | .setOverlayView(overlayView)
133 | .show();
134 |
135 | ```
136 |
137 | With this possibilities you can achieve something like this:
138 |
139 | 
140 |
141 | You can take a look at [sample project][sample] for more information.
142 |
