有没有办法将互联网上的图像延迟加载到远程视图中。
remoteView.setImageViewBitmap(R.id.image, UrlUtils.loadBitmap(bitmapUrl));
我使用此功能,但它在短时间内阻止了我的小部件。
public static Bitmap loadBitmap(String url) {
Bitmap bitmap = null;
InputStream in = null;
BufferedOutputStream out = null;
try {
in = new BufferedInputStream(getPageInputStream(url));
final ByteArrayOutputStream dataStream = new ByteArrayOutputStream();
out = new BufferedOutputStream(dataStream);
Utils.copy(in, out);
out.flush();
final byte[] data = dataStream.toByteArray();
BitmapFactory.Options options = new BitmapFactory.Options();
// options.inSampleSize = 1;
bitmap = BitmapFactory.decodeByteArray(data, 0, data.length,
options);
in.close();
out.close();
} catch (IOException e) {
e.printStackTrace();
}
return bitmap;
}
谢谢
