java - How to listen for a single field in Firebase's Android SDK -


i trying figure out way listen single item using firebase api's. far figured out how query single item using orderbykey , equalto functions.

i tried similar listening single value, anytime change 1 value gives me whole database items when want 1 changed. i've added valueeventlistener , childeventlistener, seemed similar things.

is there way listen single item , return single item?

if understand correctly, lets assume firebase setup summary:

 yourapp:    "node": {        "subnode1": {           "value1": value,           "value2": value,           "subsubnode":{               //....values....//            },        },   "node2": { ... },   "node3": { ... }   //...and on ..// },

and trying listen value2? if case, is not possible. access this, need listen parent node; subnode1, , onchildevent, value.

however, if trying listen subnode1 or subsubnode, that is possible. providing path object when creating firebase object.

if post more code, modify accordingly better answer question.

edit

say wanted retrieve subsubnode. create firebase reference , add listener:

 firebase firebase = new firebase("yourfirebaseurl").child("node").child("subsubnode");  firebase.addchildeventlistener(new .....);

bash - Performing variable substitution in a string -

i have string contains use of variable, , i'd substitute variable's value string. right best have is #!/bin/bash foo='$name; echo bar' name="the name" expanded="$(eval echo "$foo")" echo "$expanded" which has obvious defects: prints the name bar while i'd print the name; echo bar instead of eval can bash's regex matching bash's string replacement: foo='$name; echo bar' name="the name" [[ "$foo" =~ \$([[:alnum:]]+) ]] && s="${!bash_rematch[1]}" && expanded="${foo/\$${bash_rematch[1]}/$s}" echo "$expanded" name; echo bar
