why it only shows the latest data from the json array

Question

These are my JSON data:

[
    {"haberBaslik":"ekrem kimdir?"},
    {"haberBaslik":"doğa kimdir?"},
    {"haberBaslik":"biz kimiz?"},
    {"haberBaslik":"fatih naptı?"}
]

and this code only shows the latest data, but I need to show my all data

JSONArray jsonarray = new JSONArray(s);
for (int i = 0; i < jsonarray.length(); i++) {
    JSONObject jsonobject = jsonarray.getJSONObject(i);
    String Haberbaslik = jsonobject.getString("haberBaslik");
    tv1.setText(Haberbaslik);
}

It shows the latest data, because you overwrite tv1 each time until the end. — Carnal, Apr 26 '19 at 12:30

  JSONObject jsonobject = jsonarray.getJSONObject(i);
  String Haberbaslik = jsonobject.getString("haberBaslik");
  tv1.setText(tv1.getText()+ " "+Haberbaslik);
 }

This is more right, will print all the values with no space in between – Carnal Apr 26 '19 at 12:33
@Carnal added spacing – Basi Apr 26 '19 at 12:34
Or alternate you can use `tv1.append()` instead of `tv1.setText()` – AskNilesh Apr 26 '19 at 12:34
Consider using `StringBuilder` when joining strings, it's far more efficient. – Tom Mettam Apr 26 '19 at 12:39
