How to blur an view using the new RenderEffect Library?-CodePudding

Android introduced RenderEffect in the latest Android S. How do i use this in my project?

CodePudding user response：

RenderEffect API only exits in API level 31 and succeeds. For earlier version compatibility, you have to work with Bitmap Here is the very instructive group of blog post links RenderEffect and Series of Image blurring; I believe it will be effective for you.

Works only on Android 12 as of now so is not a universal solution yet

To blur a view

1 Set your target SDK and compile SDK to Android S in build.gradle

2.Use Render Effect

3.set blur as follows

your_view.setRenderEffect(
     RenderEffect.createBlurEffect(
     30f, //radius X
     30f, //Radius Y
     Shader.TileMode.[X]// X=CLAMP,DECAL,MIRROR,REPEAT
)

The 4 types of blend mode are

CLAMP- Replicate the edge color if the shader draws outside of its original bounds

DECAL- Render the shader's image pixels only within its original bounds

MIRROR- Repeat the shader's image horizontally and vertically, alternating mirror images so that adjacent images always seam.

REPEAT - Repeat the shader's image horizontally and vertically.
