提供我有一個圖像URL陣列,我試圖下載所有這些圖像一個接一個使用滑翔。目前,我可以在提供URL時下載單個圖像。這裏是代碼:如何使用Glide [Android]下載多個圖像?
private void downx()
{
File sd = getExternalCacheDir();
File folder = new File(sd, "/mobio/");
if (!folder.exists()) {
if (!folder.mkdir()) {
Log.e("ERROR", "Cannot create a directory!");
} else {
folder.mkdirs();
}
}
final File[] fileName = {new File(folder, "one.jpg"), new File(folder, "two.jpg"),new File(folder, "three.jpg")};
new AsyncTask<Void, Void, Void>() {
@Override
protected Void doInBackground(Void... params)
{
try
{
theBitmap = Glide.
with(getApplicationContext()).
load(urls[2]).
asBitmap().
into(Target.SIZE_ORIGINAL,Target.SIZE_ORIGINAL).
get();
}
catch (final ExecutionException e)
{
Log.e("TAG", e.getMessage());
}
catch (final InterruptedException e)
{
Log.e("TAG", e.getMessage());
}
return null;
}
@Override
protected void onPostExecute(Void dummy) {
if (null != theBitmap) {
// The full bitmap should be available here
Log.d("TAG", "Image loaded");
Log.e("GLIDE","I am Ready");
try {
FileOutputStream outputStream = new FileOutputStream(String.valueOf(fileName[1]));
theBitmap.compress(Bitmap.CompressFormat.JPEG, 100, outputStream);
outputStream.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}.execute();
}
現在問題是:我該採取什麼樣的方法,如果我需要下載多個圖像,以及如何強制我的代碼,以適應處理多個下載?
