android - Display data parsed from Json with Gson in a recyclerview -

i have json string:

 {   "status": "true",    "result": {     "rows": {      "row": {        "status": true,         "subareas": [         {          "nome": "associacao utente",          "id": 9,          "grafs": {           "rows": {             "row": {               "id": 6,               "nome": "associacao utente",               "tipo": "pie",               "serv": "mv_as_utente_por_negocio",               "periodo": "ano"             }           }         }       },       {         "nome": "chaves",         "id": 60,         "grafs": {           "rows": [             {               "id": 35,               "nome": "chaves criados por ano",               "tipo": "linha",               "serv": "mv_assoc_total_chaves",               "periodo": "ano"             },             {               "id": 592,               "nome": "chaves associado ao user portal",               "tipo": "bar",               "serv": "mv_assoc_user_chaves",               "periodo": "todos"             },             {               "id": 593,               "nome": "chaves associado ao negocios",               "tipo": "bar",               "serv": "mv_assoc_chaves",               "periodo": "todos"             }           ]         }       }     ]   } } } } 

which deserialized pojo gson. below show deserializer:

example.java

public class example { private string status; private result result;  public string getstatus() {     return status; } public void setstatus(string status) {     status = status; } public result getresult() {     return result; } public void setresult(result result) {     result = result; } @override public string tostring() {     return "example [status=" + status + ", result=" + result + "]"; } 

result.java

public class result { private rows rows;  public rows getrows() {     return rows; }  public void setrows(rows rows) {     this.rows = rows; }  @override public string tostring() {     return "result [rows=" + rows + "]"; } 

rows.java

public class rows { private row row;  public row getrow() {     return row; } public void setrow(row row) {     this.row = row; } @override public string tostring() {     return "rows [row=" + row + "]"; } 

row.java

public class row { private boolean status; private list<subarea> subareas = new arraylist<>();  public boolean getstatus() {     return status; } public void setstatus(boolean status) {     this.status = status; } public list<subarea> getsubareas() {     return subareas; } public void setsubareas(list<subarea> subareas) {     this.subareas = subareas; } @override public string tostring() {     return "row [status=" + status + ", subareas=" + subareas + "]"; } 

subarea.java

public class subarea { private string nome; private integer id; private grafs grafs; public string getnome() {     return nome; } public void setnome(string nome) {     this.nome = nome; } public integer getid() {     return id; } public void setid(integer id) {     this.id = id; } public grafs getgrafs() {     return grafs; } public void setgrafs(grafs grafs) {     this.grafs = grafs; } @override public string tostring() {     return "subarea [nome=" + nome + ", id=" + id + ", grafs=" + grafs             + "]"; } 

grafs.java

public class grafs { private row_[] rows;  public list<row_> getrows() {     return new linkedlist<row_>( arrays.aslist(rows)); } public void setrows(list<row_> rows) {     this.rows = (row_[]) rows.toarray(); } @override public string tostring() {     return "grafs [rows=" + rows[0] + "]"; } public static class row_deserializer implements jsondeserializer<row_[]>{     @override     public row_[] deserialize(jsonelement json, type typeoft,     jsondeserializationcontext context) throws jsonparseexception{         if(json instanceof jsonarray){             return new gson().fromjson(json, row_[].class);         }         system.out.println("ola");         rows1 child = context.deserialize(json, rows1.class);         system.out.println(child.getrow().getid());         return new row_[] {child.getrow()};     } } 

row_.java

public class row_ { private integer id; private string nome; private string serv; private string periodo;   public integer getid() {     return id; } public void setid(integer id) {     this.id = id; } public string getnome() {     return nome; } public void setnome(string nome) {     this.nome = nome; } public string getserv() {     return serv; } public void setserv(string serv) {     this.serv = serv; } public string getperiodo() {     return periodo; } public void setperiodo(string periodo) {     this.periodo = periodo; } @override public string tostring() {     return "row_ [id=" + id + ", nome=" + nome + ", serv=" + serv             + ", periodo=" + periodo + "]"; } 

this working fine deserialize json. need doing display of data in recyclerview can produce following output. want display each subarea grafs name. first subarea has 1 grafs , second has grafs can see in output.

you can parse json line:

new gson().fromjson(json, example.class); 

this simple way.
