Requirements
- Fresco v.0.12.0 and higher
- SDK 14 and and higher
Download
Download via Gradle:
compile 'com.github.stfalcon:frescoimageviewer:0.4.1'
or Maven:
<dependency>
<groupId>com.github.stfalcon</groupId>
<artifactId>frescoimageviewer</artifactId>
<version>0.4.1</version>
<type>pom</type>
</dependency>
Usage
All you need to show a viewer is pass the context, start position and List or String[] into builder and call show()
.
new ImageViewer.Builder(context, list)
.setStartPosition(startPosition)
.show();
Piece of cake! 🍰 😉
Customizing
You can also customize a viewer to fit your needs.
Background
Use setBackgroundColorRes(colorRes)
or setBackgroundColor(colorInt)
to set color for fading background.
Custom overlay view
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
.
Custom drawee hierarchy
Of course, according to Fresco flexibility, you can use your custom GenericDraweeHierarchy. To do this you simply need to create GenericDraweeHierarchyBuilder and pass it into builder:
GenericDraweeHierarchyBuilder hierarchyBuilder = GenericDraweeHierarchyBuilder.newInstance(getResources())
.setFailureImage(R.drawable.failureDrawable)
.setProgressBarImage(R.drawable.progressBarDrawable)
.setPlaceholderImage(R.drawable.placeholderDrawable);
new ImageViewer.Builder(context, urls)
...
.setCustomDraweeHierarchyBuilder(hierarchyBuilder)
.show();
But there is a limitation: default ScaleType in hierarchy is ScaleType.FIT_CENTER
, so custom value will be ignored
Image margin
Simply add margins between images with dimens with setImageMargin(context, dimen) or in px
using setImageMarginPx(marginPx)
.
Status bar visibility
To show/hide status bar in view mode you can set hideStatusBar(boolean)
in builder. The default value is strue
.
Here is an example that sets possible options:
new ImageViewer.Builder(context, list)
.setStartPosition(startPosition)
//.hideStatusBar(false)
.setBackgroundColorRes(colorRes)
//.setBackgroundColor(color)
.setImageMargin(R.dimen.image_margin)
.setImageChangeListener(changeListener)
.setOnDismissListener(dismissListener)
.setCustomDraweeHierarchyBuilder(hierarchyBuilder)
.setOverlayView(overlayView)
.show();
With this possibilities you can achieve something like this:
