Firebase
我循环上传图片并更新ProgressDialog
每个图像:
(我在一个Fragment
,所以我getActivity()
在调用之前使用runOnUiThread()
)
List<Bitmap> bitmaps;
int picCounter = 1;
...
progressDialog = ProgressDialog.show
(getContext(), "sending...", "just a minute", false, false);
new Thread(new Runnable() {
@Override
public void run() {
for (int i = 0; i < bitmaps.size(); i++) {
String filename = String.valueOf(i);
uploadPic(bitmaps.get(i), "img" + filename, new MyCallback() {
@Override
public void onFinish() {
picCounter++;
Objects.requireNonNull(getActivity()).runOnUiThread(new Runnable() {
public void run() {
progressDialog.setTitle ("upoading " + picCounter + "image from " + bitmaps.size());
}
});
}
});
}
}
}).start();
上传图片方法:
public interface MyCallback { void onFinish ();}
private void uploadPic(final Bitmap bitmap, final String fileName, final MyCallback callback) {
... // uploading to firebase and then:
callback.onFinish();
}
