Android: Strange out of memory issue while loading an image to a Bitmap object

我正在从 Url 下载图像并显示它们。在下载时它给内存不足错误:位图大小超出 VM 预算。我正在使用可绘制的。代码如下:

HttpClient httpclient= new DefaultHttpClient();
HttpResponse response=(HttpResponse)httpclient.execute(httpRequest);
HttpEntity entity= response.getEntity();
BufferedHttpEntity bufHttpEntity=new BufferedHttpEntity(entity);
InputStream instream = bufHttpEntity.getContent();

Bitmap bm = BitmapFactory.decodeStream(instream);
Bitmap useThisBitmap = 
Bitmap.createScaledBitmap(bm,bm.getWidth(),bm.getHeight(), true);
bm.recycle();
BitmapDrawable bt= new BitmapDrawable(useThisBitmap);
System.gc();

这里是错误:

`05-28 14:55:47.251: ERROR/AndroidRuntime(4188): 
 java.lang.OutOfMemoryError: bitmap size exceeds VM budget`

Answer 1

使用 decodeStream(is, outPadding, opts) 和

BitmapFactory.Options opts=new BitmapFactory.Options();
opts.inDither=false;                     //Disable Dithering mode
opts.inPurgeable=true;                   //Tell to gc that whether it needs free memory, the Bitmap can be cleared
opts.inInputShareable=true;              //Which kind of reference will be used to recover the Bitmap data after being clear, when it will be used in the future
opts.inTempStorage=new byte[32 * 1024];
