推荐答案

检索网址时，您需要添加侦听器.

You need to add listeners when retrieving the url.

请阅读文档

taskSnapshot.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
    @Override
    public void onSuccess(Uri uri) {
        // Got the uri
        ImageUpload imageUpload = new ImageUpload(editText5.getText().toString(), uri.toString());
        // Wrap with Uri.parse() when retrieving

        String uploadId = mDatabaseRef.push().getKey();
        mDatabaseRef.child(uploadId).setValue(imageUpload);
    }
}).addOnFailureListener(new OnFailureListener() {
    @Override
    public void onFailure(@NonNull Exception exception) {
        // Handle any errors
    }
});
