私のプロジェクトにこのコードがあると仮定します。このコードの問題は何だろうと思っています。あなたの誰かが私を助けることができれば、私はとてもうれしいです. ここをクリックて、フォーマットされた json 文字列を表示します。

現在の json 文字列playersはJSONObjectJSONArray内にあるため、最初に main からJSONObject を取得し、次にJSONArrayresultを次のように取得する必要があります。resultJSONObjectplayers

JSONObject result = new JSONObject(<JSON_STRING_HERE>);
 // get result JSONObject
JSONObject jsonobj_result = result.optJSONObject("result");
 // get players JSONArray
JSONArray players = jsonobj_result.optJSONArray("players");
Player player; String data = null;
for (int i = 0; i < players.length(); i++) {
    player = new Player(players.getJSONObject(i));
    data += player.getFormattedHero();
}

String data = null;

と取り換える

StringBuffer data = new StringBuffer();

良いかもしれません。
