BlurSelect - is a library for selecting view and blur background

Setup

1) App level build.gradle

dependencies {
    implementation 'com.github.Bodiart:BlurSelect:1.4.1'
}

2) Application class

package com.example

class App: Application() {
    override fun onCreate() {
        super.onCreate()
        BlurSelect.init(this)
    }
}

Dont forget to add this class in manifest (like this):

<application
    ...
    android:name="com.example.App"
    ...
/>

Usage

Just call

BlurSelect.selectView(selectView, viewForCard, config)

Where:

• selectView - view what you want to focus
• viewForCard - layout which you want to show after select (you can specify size as you want, or it will be calculated automatically)
• config - BlurConfig object for determining animation durations and values, viewForCard size and other (there are some prepared configs for different animations)

To add viewForCard listeners:

val blurSelect = BlurSelect.selectView(selectView, viewForCard, config)
blurSelect.addCardListener(viewId, listener)

Prepared configs

1) BlurConfigs.withShadowConfig(elevationFrom, elevationTo)

• elevationFrom - start shadow animation with this elevation
• elevationTo - end shadow animation with this elevation

Enables shadow animation. If you are using CardView as selectView and you already have elevation, just specify

elevationFrom = CardView.cardElevation

2) BlurConfigs.withRadiusConfig(radiusFrom, radiusTo)

• radiusFrom - start animation with this radius
• radiusTo - end animation with this radius

If you are using CardView as selectView and you already have corner radius, just specify

radiusFrom = CardView.radius

3) BlurConfigs.onlyScaleUpConfig(scaleUpTo)

• scaleUpTo - end scale up animation with this scale (t can be lesser than 1)

4) BlurConfigs.withShadowAndRadiusConfig(elevationFrom, elevationTo, radiusFrom, radiusTo)

5) BlurConfigs.onlyScaleUpWithShadowConfig(scaleUpTo, elevationFrom, elevationTo)

6) BlurConfigs.onlyScaleUpWithRadiusConfig(scaleUpTo, radiusFrom, radiusTo)

7) BlurConfigs.onlyScaleUpWithShadowAndRadiusConfig(scaleUpTo, elevationFrom, elevationTo, radiusFrom, radiusTo)

Config properties

Blurred background

• blurredBgBlurRadius - radius of background blur factor
• blurredBgBlurDownScaleFactor - background view bitmap downscale factor

Card (view that appears when selectView focused)

• cardAutoCalculateInnerViewSize - auto calculate card width and height (if you want to specify size manually - set it to false)
• cardTopAdditionMargin - additional card vertical margin
• cardStartEndAdditionMargin - additional card horizontal margin

SelectView (view for focus)

• selectViewCardDuplicateCardParams - duplicate card view params, such as elevation, background color and radius. If selectView is CardView - it can duplicate params. Or you can set it to false and specify radius, background color and elevation (by setting shadow animation) manually
• selectViewCardShadowAnimEnabled - enable shadow (elevation) animation. Specify selectViewCardAnimDurationShadowOn, selectViewCardAnimDurationShadowOff, selectViewCardAnimValueShadowOnFrom, selectViewCardAnimValueShadowOnTo, selectViewCardAnimValueShadowOffTo
• selectViewCardRadiusAnimEnabled - enable radius (card corner radius) animation. Specify selectViewCardAnimDurationRadiusOn, selectViewCardAnimDurationRadiusOff, selectViewCardAnimValueRadiusOnFrom, selectViewCardAnimValueRadiusOnTo, selectViewCardAnimValueRadiusOffTo
