原标题:How to Retrieve image from url

我正在讨论APIC。 我们提供了图像的乌尔都语。 我不得不在我的清单活动中展示乌尔都语的形象。 我怎么能树立形象? 我花了近两天的时间。 我在我的活动中使用图像。

在你的活动中,你将使用你能够做到的固定地址(Bitmap bmt)获得 Bit物体。

Method:

public Bitmap getBitmap(String url) {
            Log.d("getBitmap", "getBitmap");
            Bitmap bm = null;
            try {
                URL aURL = new URL(url);
                URLConnection conn = aURL.openConnection();
                conn.connect();
                InputStream is = conn.getInputStream();
                BufferedInputStream bis = new BufferedInputStream(is);
                bm = BitmapFactory.decodeStream(new FlushedInputStream(is));
                bis.close();
                is.close();
            } catch (Exception e) {
                e.printStackTrace();
            } finally {

            }
            return bm;
        }

内部班级:

class FlushedInputStream extends FilterInputStream {
        public FlushedInputStream(InputStream inputStream) {
            super(inputStream);
        }
    }
问题回答

利用该密码从档案中获取模拟图像,

Bitmap bitmapImage = BitmapFactory.decodeFile(//File path);
    imageView.setImageBitmap(bitmapImage);

并且你可以通过以下方法从里传出档案:

private File getFileFromUri(Uri uri) throws IOException {
    Cursor cursor = managedQuery(uri, null, null, null, null);
    if (cursor.getCount() == 0) {
        throw new IOException(String.format("cannot find data from %s",
                uri.toString()));
    } else {
        cursor.moveToFirst();
    }

    String filePath = cursor.getString(cursor
            .getColumnIndex(Video.VideoColumns.DATA));

    File file = new File(filePath);
    cursor.close();
    return file;
}

希望这将有助于你们
