Android Question How to get the map in the map ?

[fash866]

please see my code:

    Dim test As Map
    test.Initialize
    test.Put("a","abc")
    test.Put("b","234")
   
    Dim test2 As Map
    test2.Initialize
    test2.put("a1","111")
    test2.put("a2","222")
   
    test.Put("c",test2)
   
    File.WriteMap(File.DirInternal,"tttt",test)
   
    Dim ok As Map
    ok.Initialize
    ok=File.ReadMap(File.DirInternal,"tttt")

    Dim ok2 As Map
    ok2 = ok.Get("c") ' Here is the wrong code, How to get the "test2"

Did you get any error message? WHAT ERROR MESSAGE?????

To save a map in a map you need to write and read a OBJECT
Writemap does only work on primitives int, long, real, string

Use Keyvaluestore and write (and reread) the map with

' write the map
kvs.PutObject("map",m)

' read the map
dim m as map =  kvs.GetObject("map")

You are not initializing the "ok2" map.

File.ReadMap returns a map with strings (as File.WriteMap creates a text file).

You should use KeyValueStore class instead.

You are not initializing the "ok2" map.

No need to initialize it if you are assigning an initialized map to it.

Simplified example, this is perfectly valid:

Dim map1 as Map
map1.Initialize

Dim map2 as Map
map2=map1

Yes ! I need it！
