我無法解決如何將圖像下載到我的小工具!Android:小工具加載圖像
在我的小部件中,我使用url,title加載AsyncTask json,然後在TextView中顯示標題,我需要從url加載圖像。
我試着用這個,但圖片的加載,現在顯示
class LoadImages extends AsyncTask<Void, Void, Bitmap>{
@Override
protected Bitmap doInBackground(Void... params) {
Bitmap bitmap = null;
InputStream in = null;
BufferedOutputStream out = null;
try {
in = new BufferedInputStream(new URL("http://mysite/simple.img").openStream());
final ByteArrayOutputStream dataStream = new ByteArrayOutputStream();
out = new BufferedOutputStream(dataStream);
out.flush();
final byte[] data = dataStream.toByteArray();
BitmapFactory.Options options = new BitmapFactory.Options();
//options.inSampleSize = 1;
bitmap = BitmapFactory.decodeByteArray(data, 0, data.length,options);
Log.e("Log", "Yeah");
} catch (IOException e) {
Log.e("Log", "Could not load Bitmap from: " + "mysiteg");
}
return bitmap;
}
}
和update我把這個
LoadImages load = new LoadImages();
load.execute();
Bitmap bitmap = load.get();
update.setImageViewBitmap(R.id.imageView0, bitmap);
確保圖像位於該網址上。 – Subburaj
