这是我的firebase数据库JSON。
我从我的适配器调用MapActivity并且我传递了这些数据：
@Override
public void onClick(View v) {
int position = getAdapterPosition();
Hotel hotel = this.hotels.get(position);
Intent intent = new Intent(this.ctx, MyHotelDetailsMapActivity.class);
intent.putExtra("author", hotel.getAuthor());
intent.putExtra("food", String.valueOf(hotel.getFood()));
intent.putExtra("service", String.valueOf(hotel.getService()));
intent.putExtra("comfort", String.valueOf(hotel.getComfort()));
intent.putExtra("name", hotel.getName());
intent.putExtra("review", hotel.getReview());
intent.putExtra("latit", String.valueOf(hotel.getLatit()));
intent.putExtra("longit", String.valueOf(hotel.getLongit()));
intent.putExtra("rating", String.valueOf(hotel.getRating()));
this.ctx.startActivity(intent);
}
在我的MapActivity中，我有一个对话框来编辑一些数据或删除酒店：
@Override
public boolean onMarkerClick(Marker marker) {
final double lat = Double.valueOf(getIntent().getStringExtra("latit"));
final double lon = Double.valueOf(getIntent().getStringExtra("longit"));
LayoutInflater inflater = LayoutInflater.from(MyHotelDetailsMapActivity.this);
View contentView = inflater.inflate(R.layout.dialog_edit, null);
final EditText hotelName = (EditText) contentView.findViewById(R.id.hotel_name_edittext);
final RatingBar ratingBarFood = (RatingBar) contentView.findViewById(R.id.hotel_ratingbar_food);
final RatingBar ratingBarService = (RatingBar) contentView.findViewById(R.id.hotel_ratingbar_service);
final RatingBar ratingBarComfort = (RatingBar) contentView.findViewById(R.id.hotel_ratingbar_comfort);
final EditText comment = (EditText) contentView.findViewById(R.id.comment);
hotelName.setText(getIntent().getStringExtra("name"));
ratingBarFood.setRating(Float.valueOf(getIntent().getStringExtra("food")));
ratingBarService.setRating(Float.valueOf(getIntent().getStringExtra("service")));
ratingBarComfort.setRating(Float.valueOf(getIntent().getStringExtra("comfort")));
comment.setText(getIntent().getStringExtra("review"));
final Dialog dialog = new AlertDialog.Builder(MyHotelDetailsMapActivity.this)
.setTitle("edit")
.setView(contentView)
.setNegativeButton(android.R.string.cancel, null)
.setPositiveButton("save", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
float averageRating = ((ratingBarComfort.getRating() + ratingBarFood.getRating() + ratingBarService.getRating()) / 3);
String hotelUid = getIntent().getStringExtra("name");
String uid = firHotRef.getAuth().getUid();
autName = getIntent().getStringExtra("author");
final Firebase hotelsRef = new Firebase("https://josip-my-application.firebaseio.com/Users/" + uid + "/hotel/").child(hotelUid);
hotelsRef.setValue(rateHotel(hotelName.getText().toString(),
lat, lon, autName, ratingBarFood.getRating(), ratingBarService.getRating(),
ratingBarComfort.getRating(), averageRating, comment.getText().toString()));
dialog.dismiss();
}
})
.setNeutralButton("delete", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
String hotelUid = getIntent().getStringExtra("name");
String uid = firHotRef.getAuth().getUid();
final Firebase hotelsRef = new Firebase("https://josip-my-application.firebaseio.com/Users/" + uid + "/hotel/").child(hotelUid);
hotelsRef.removeValue();
dialog.dismiss();
Intent i = new Intent(MyHotelDetailsMapActivity.this, ListActivity.class);
i.putExtra("username", getIntent().getStringExtra("author"));
startActivity(i);
}
})
.create();
dialog.show();
return true;
}
public Map<String, Object> rateHotel(String name, double lat, double lon, String author,float foodRating,float serviceRating,float comfortRating,float averageRating, String review) {
Map<String, Object> hotel = new HashMap<>();
hotel.put("name", name);
hotel.put("latit", lat);
hotel.put("longit", lon);
hotel.put("author", author);
hotel.put("food", foodRating);
hotel.put("service", serviceRating);
hotel.put("comfort", comfortRating);
hotel.put("rating", averageRating);
hotel.put("review", review);
return hotel;
}
当我点击肯定按钮保存更改时，如果我将酒店名称保留在适配器中，则所有其他字段都会更新，但如果我重命名酒店名称，我会得到不同的子节点名称，就像在我的JSON中一样（我有子节点名称巴黎，但我将酒店名称重命名为Pariss），所以当我点击中性按钮删除该酒店时，无法找到...有没有办法重命名子节点名称，在这种情况下，如果我将巴黎重新命名为Pariss，那儿童节点也变成了Pariss？
