类 DisplayImageOptions

java.lang.Object

com.nostra13.universalimageloader.core.DisplayImageOptions

public final class DisplayImageOptions
extends Object

Contains options for image display. Defines:

• whether stub image will be displayed in image aware view during image loading
• whether stub image will be displayed in image aware view if empty URI is passed
• whether stub image will be displayed in image aware view if image loading fails
• whether image aware view should be reset before image loading start
• whether loaded image will be cached in memory
• whether loaded image will be cached on disk
• image scale type
• decoding options (including bitmap decoding configuration)
• delay before loading of image
• whether consider EXIF parameters of image
• auxiliary object which will be passed to ImageDownloader
• pre-processor for image Bitmap (before caching in memory)
• post-processor for image Bitmap (after caching in memory, before displaying)
• how decoded Bitmap will be displayed

You can create instance:

• with DisplayImageOptions.Builder:
  i.e. : new DisplayImageOptions.Builder().cacheInMemory(). showImageOnLoading().build()
  
• or by static method: createSimple()

从以下版本开始:

createSimple

public static DisplayImageOptions createSimple()

Creates options appropriate for single displaying:

• View will not be reset before loading
• Loaded image will not be cached in memory
• Loaded image will not be cached on disk
• ImageScaleType.IN_SAMPLE_POWER_OF_2 decoding type will be used
• Bitmap.Config#ARGB_8888 bitmap config will be used for image decoding
• SimpleBitmapDisplayer will be used for image displaying

These option are appropriate for simple single-use image (from drawables or from Internet) displaying.
