I have a class that works until I try to use JSONFunkcije class. (remove comments)
在尝试使用JSONFunkcije类之前，我有一个类。(删除评论)
TaksiDetalji.java:
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;
}
}
When I remove comments I get the following error: (Unfortunately, Oceni Taksi has stopped = no layout loaded)
当我删除注释时，我得到了以下错误:(不幸的是，Oceni Taksi已经停止=没有布局加载)

I think that the problem in JSON and I am sure that the problem is in the JSONfunkcije.java but I can't find anything.
我认为JSON的问题，我确信问题在于JSONfunkcije。java，但我什么也找不到。

The problem is in JSONFunkcije.java in DetaljiSluzba().
问题在于JSONFunkcije。java在DetaljiSluzba()。
I forgot to put niz=new ArrayList<String>();
我忘记输入niz=new ArrayList
Now works. Tnx.
现在工作。Tnx。
