android – 如何使用FirebaseListAdapter获取键和值

这段代码获取值并在listview中设置它们我想获取密钥也使用它们,请查看图像查看数据库示例

FirebaseListAdapter firebaseListAdapter = new FirebaseListAdapter<String>(this, String.class, R.layout.users_list, usersUrl) {
        @Override
        protected void populateView(View view, String base64Image, int i) {
            //((TextView) view.findViewById(android.R.id.text1)).setText(s);
            byte[] imageAsBytes = Base64.decode(base64Image.getBytes(), Base64.DEFAULT);
            Bitmap bitmap =BitmapFactory.decodeByteArray(imageAsBytes, 0, imageAsBytes.length);

            ((ImageView)view.findViewById(R.id.imageView1)).setImageBitmap(RoundedImageView.getCroppedBitmap(bitmap,100));



        }
    };

database Image

解决方法:

您可以通过调用getRef(position)获取当前项的DatabaseReference：

protected void populateView(View view, String base64Image, int position) {
    DatabaseReference itemRef = getRef(position);
    String itemKey = itemRef.getKey();
    ...
