[Resolvido] Android - Limpar Conteúdo Json

Recommended Posts

Rick45

Boas pessoal.

Eu tenho um objecto json que está acessível em toda a Activity:

JSONObject obj = new JSONObject();   // JSON Principal

este objecto é composto por um objecto chamado Dados e um array de objectos:

dados.put("nome", nome);			   // objecto dados
obj.put("Dados", dados);				 // Coloco objecto de dados dentro o objecto principal

coordsObj.put( "lat", latvalue );	  //objecto coords que vai ser colocado dentro de um JSONARRAY
coords.put( coordsObj );			   // JSONARRAY que contem os objectos coordsObj

obj.put( "Coordnadas", coords ); // Coloco o array de coordnadas dentro o objecto principal,

o que queria fazer era colocar um butao e ao clicar nele apagava o JSONObject obj. tenho o butao ae tudo a funcionar so que clico nele e nao apaga, já tentei de varias maneiras sem sucesso :S.

O que me recomendam para apagar?

estava a fazer assim.

for(int i=0;i<obj.length();i++){
obj.remove("Dados");
obj.remove("Coordnadas");

}

E se fizeres:

obj = new JSONObject();

ja descobri o problema, essa maneira funcionava, so que estava a esquecer-me de fazer o mesmo ao array, os valores de obj estavam limpos, so que quando punha valores no array e o enviava para o obj os antigos do array ainda la estavem,

obrigado
