SnowfallView attributes

Element	Attribute	Related methos(s)	Default value
Alpha max	app:snowflakeAlphaMax		250
Alpha min	app:snowflakeAlphaMin		150
Angle max	app:snowflakeAngleMax		10
Image	app:snowflakeImage	setSnowflakeImageDrawable setSnowflakeImageBitmap setSnowflakeResource	null
Size max	app:snowflakeSizeMax		8dp
Size min	app:snowflakeSizeMin		2dp
Speed max	app:snowflakeSpeedMax		8
Speed min	app:snowflakeSpeedMin		2
Already falling	app:snowflakesAlreadyFalling		false
Fading enabled	app:snowflakesFadingEnabled		false
Multiple Images	app:snowflakesMultipleImages		false
Number of elements	app:snowflakesNum		200

Alternatively, you can also style the Snowfall View programmatically by calling the methods:

It's also possible to add the image of type drawable using the following method:

• setSnowflakeImageDrawable(Drawable)

It's also possible to add the image of type bitmap using the following method:

• setSnowflakeImageBitmap(Bitmap)

It's also possible to add the image of type resource, e.g. R.drawable.snowflake using the following method:

• setSnowflakeResource(Resource)

To add multiple images, use the following methods, following the rule of the above methods:

• setSnowflakeImageDrawables(List<Drawable>)
• setSnowflakeImageBitmaps(List<Bitmap>)
• setSnowflakeResources(List<Resource>)

Usage

Default implementation with round snowflakes:

<com.leodan11.snowfall.SnowfallView
      android:layout_width="match_parent"
      android:layout_height="match_parent" />

Fully customized implementation:

<com.leodan11.snowfall.SnowfallView
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      app:snowflakesNum="250"
      app:snowflakeAlphaMin="150"
      app:snowflakeAlphaMax="255"
      app:snowflakeAngleMax="5"
      app:snowflakeSizeMin="8dp"
      app:snowflakeSizeMax="32dp"
      app:snowflakeSpeedMin="4"
      app:snowflakeSpeedMax="12"
      app:snowflakesFadingEnabled="true"
      app:snowflakesAlreadyFalling="false"
      app:snowflakesMultipleImages="false"
      app:snowflakeImage="@drawable/snowflake"/>
