PacButton

Created this cool video/photo switch animation from Oleg Frolov as android library.

USAGE

Just add PacButton view in your layout XML and PacButton library in your project via Gradle:

dependencies {

implementation 'com.bitvale:pacbutton:1.0.0' 
}

XML

<com.bitvale.pacbutton.PacButton
  android:id="@+id/pac_button"
  android:layout_width="@dimen/pac_size"
  android:layout_height="@dimen/pac_size"
  app:topIcon="@drawable/ic_video"
  app:bottomIcon="@drawable/ic_photo"
  app:iconHeight="@dimen/icon_size"
  app:iconWidth="@dimen/icon_size"
  app:pacGradientColor_1="@color/gradient_color_1"
  app:pacGradientColor_2="@color/gradient_color_2" />

You must use the following properties in your XML to change your PacButton.

Properties:

• app:topIcon (drawable) -> default none
• app:bottomIcon (drawable) -> default none
• app:iconHeight (dimension) -> default none
• app:iconWidth (dimension) -> default none
• app:pacColor (color) -> default none
• app:pacGradientColor_1 (color) -> default #7651F8
• app:pacGradientColor_2 (color) -> default #E74996

You can use solid color with pacColor property or gradient with pacGradientColor properties.

Kotlin

pac_button.setSelectAction {

  if (it) some_image.setImageResource(R.drawable.ic_video_cam)
  else some_image.setImageResource(R.drawable.ic_photo_cam) 
}
  pac_button.setAnimationUpdateListener {
 progress ->
  some_image.alpha = 1 - progress 
}
