ImageSlide in Kotlin for Android

Usage

1. Add to project

Add jcenter() to repository in your project's build.gradle:

allprojects {
    repositories {
        ...
        jcenter()
    }
}

Add imageslide to dependencies in your app's build.gradle:

dependencies {
    ...
    implementation 'com.feiyilin:imageslide:0.1.2'
}

2. Update layout xml

For the activity that you want to show the imagelide, add a FrameLayout to the end of its layout, e.g.,

<FrameLayout
    android:id="@+id/imageslide_fragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

3. Update activity

Init the imageslide fragment

class MainActivity : ImageSlideActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        ...    
        // initialize the imageslide fragment
        initImageSlideFragment(R.id.imageslide_fragment)
    }

Show imageslide by calling show, e.g.,

val images = mutableListOf<ImageSlideItem>()
for (image in data) {
   val item = ImageSlideResItem().image(image)
   images.add(item)
}
imageSlideFragment.show(images, index)

Or check ImageSlideActivity if you want to use ImageSlideFragment directly in the activity.

ImageSlideItem

• ImageSlideResItem is to load image from resource id, e.g.,

val item = ImageSlideResItem().image(imageResId)

• ImageSlidePathItem is to load image from path string, e.g.,

// add file resource
val item = ImageSlidePathItem().image("file:///android_asset/myimage.png")
// add url resource
val item2 = ImageSlidePathItem().image("http://i.imgur.com/DvpvklR.png")

To create a custom imageslide item

1. derive a custom item from ImageSlideItem

open class ImageSlideCustomItem: ImageSlideItem() {
...
}

2. override load function to load the image into an ImageView

open class ImageSlideCustomItem: ImageSlideItem() {
    ...
    override fun load(view: ImageView?) {
        ...
    }
}
