Example usage for android.view View buildDrawingCache

Introduction

In this page you can find the example usage for android.view View buildDrawingCache.

Prototype

@Deprecated
public void buildDrawingCache(boolean autoScale) 

Source Link

Document

Forces the drawing cache to be built if the drawing cache is invalid.

If you call #buildDrawingCache() manually without calling #setDrawingCacheEnabled(boolean) setDrawingCacheEnabled(true) , you should cleanup the cache by calling #destroyDrawingCache() afterwards.

Note about auto scaling in compatibility mode: When auto scaling is not enabled, this method will create a bitmap of the same size as this view.
