我在Android的编程, 还是新的,我想要做的事情,从URL保存.gif若要SD卡
- 下载
.gif
- 保存该下载
.gif
到我的SD卡 - 叫它使用滑行
当我下载.gif
,并将其写入SD卡时,它不可读。 和比原始文件大的尺寸。
这里是我使用的代码:
URL url = new URL(imgUrl + params[0]);
File file = new File(path + params[0]);
long startTime = System.currentTimeMillis();
URLConnection ucon = url.openConnection();
Log.d(TAG, "on do in background, url open connection");
InputStream is = ucon.getInputStream();
Log.d(TAG, "on do in background, url get input stream");
BufferedInputStream bis = new BufferedInputStream(is);
Log.d(TAG, "on do in background, create buffered input stream");
ByteArrayOutputStream baos = new ByteArrayOutputStream();
Log.d(TAG, "on do in background, create buffered array output stream");
byte[] img = new byte[1024];
int current = 0;
Log.d(TAG, "on do in background, write byte to baos");
while ((current = bis.read()) != -1) {
baos.write(img, 0, current);
}
Log.d(TAG, "on do in background, done write");
Log.d(TAG, "on do in background, create fos");
FileOutputStream fos = new FileOutputStream(file);
fos.write(baos.toByteArray());
Log.d(TAG, "on do in background, write to fos");
fos.flush();
fos.close();
is.close();
Log.d(TAG, "on do in background, done write to fos");
THX之前。
thx Mike it; s really working。 awsome:D – HartzDev
