在我尝试使用 JSONFunkcije 类之前，我有一个可以工作的类。（删除评论）

TaksiDetalji.java：

public class TaksiDetalji extends Activity {

String id;
String ime;
 JSONFunkcije podatak;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.taksi_detalji);
    Intent i = getIntent();

    // getting id
    id = i.getStringExtra("id");
   podatak =  = new JSONFunkcije(id);
   List<String> sluzbice = new ArrayList<String>();
   sluzbice = podatak.DetaljiSluzbe();
   //EditText editText = (EditText)findViewById(R.id.editText1);
   //Iterator <String> it = sluzbice.iterator();
   //ime = it.next();
    //editText.setText("ime");
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.taksi_detalji, menu);
    return true;
}

     }

当我删除评论时，我收到以下错误：（不幸的是，Oceni Taksi 已停止 = 未加载布局）

}

我认为 JSON 中的问题，我确信问题出在 JSONfunkcije.java 中，但我找不到任何东西。

问题出在 DetaljiSluzba() 中的 JSONFunkcije.java 中。

我忘了放niz=new ArrayList<String>();

现在工作。肿瘤坏死因子。
