Android asynchronous download of images

For Android apps, there are several ways to download images from the Internet:

1,

2. Use aquery

Simple:

AQ. ID (R. Id. image1). Image ("http ://...")

Cache Control

Boolean memcache = false;

Boolean filecache = true;

AQ. ID (R. Id. image1). Image ("http: //...", memcache, filecache );

Down sampling

AQ. ID (R. Id. image1). Image (imageurl, true, true, 200,0)

Fallback Image

// If we are not able to load the image, use a default image

AQ. ID (R. Id. image1). Image (imageurl, true, true, 200,0, R. drawable. default_image)

Preloading

SS

　　　　

String imageUrl = "http://farm6.static.flickr.com/5035/5802797131_a729dac808_b.jpg";aq.id(R.id.image).progress(R.id.progress).image(imageUrl, false, false);

Sample grid item layout:

<Relativelayout xmlns: Android = "http://schemas.android.com/apk/res/android" Android: layout_width = "fill_parent" Android: layout_height = "100dip"> <progressbar Android: layout_width = "15dip" Android: layout_height = "15dip" Android: Id = "@ + ID/progress" Android: layout_centerinparent = "true"/> <imageview Android: Id = "@ + ID/image" Android: layout_width = "fill_parent" Android: layout_height = "75dip"/> </relativelayout>

And so on,
