我是 Volley JSONArray 的新人。我无法在 txtResponse 中 setText ，因为我总是在 onErrorResponse 上收到此错误。
这是我的 Logcat
...... com.example.simplevolley.simplevolley W / System.err：org.json.JSONException：Value [{＆＃34; com_branch_id＆＃34;：7，＆＃34; com_branch_comId＆＃34; ：1，＆＃34; com_branch_name＆＃34;：＆＃34; JT Temerloh＆＃34;，＆＃34; com_branch_manager＆＃34;：＆＃34; Tn Hj Ahmad Bin Hj Mohd Sidin＆＃34;，＆＃34; com_branch_addr＆＃34;：＆＃34; No.58，Jalan Ibrahim（Jln Masjid Abu Bakar）＆＃34;，＆＃34; com_branch_region＆＃34;：＆＃34; Temerloh＆＃34;，＆＃34; com_branch_state＆＃ 34;：＆＃34; PAHANG＆＃34;＆＃34; com_branch_country＆＃34;：＆＃34;马来西亚＆＃34;＆＃34; com_branch_poscode＆＃34;：＆＃34; 28000＆＃34;＆＃ 34; com_branch_email＆＃34;：＆＃34; tmlh@juaratravel.com.my"，＆＃34; com_branch_licence＆＃34;：空，＆＃34; com_branch_phoneNum＆＃34;：＆＃34; 09-2965625＆＃ 34;，＆＃34; com_branch_fax＆＃34;：空，＆＃34; com_branch_fb＆＃34;：空，＆＃34; com_branch_ig＆＃34;：空}，{＆＃34; com_branch_id＆＃34;：9，＆ ＃34; com_branch_comId＆＃34;：1，＆＃34; com_branch_name＆＃34;：＆＃34; JT Nibong Tebal＆＃34;，＆＃34; com_branch_manager＆＃34;：＆＃34; Pejabat Penang＆＃34;，＆ ＃34; com_branch_addr＆＃34;：＆＃34;否。 10，Tingkat Atas，Jln Pekaka 1，Tmn Pekaka，＆＃34;，＆＃34; com_branch_region＆＃34;：＆＃34; Nibong Tebal＆＃34;，＆＃34; com_branch_state＆＃34;：＆＃34; PULAU槟榔＆＃34;＆＃34; com_branch_country＆＃34;：＆＃34;马来西亚＆＃34;＆＃34; com_branch_poscode＆＃34;：＆＃34; 14300＆＃34;＆＃34; com_branch_email＆＃34 ;: ＆＃34; pen@juaratravel.com.my"，＆＃34; com_branch_licence＆＃34;：空，＆＃34; com_branch_phoneNum＆＃34;：＆＃34; 05-7171877＆＃34;＆＃34; com_branch_fax＆＃34;：＆＃34; 057161877＆＃34;＆＃34; com_branch_fb＆＃34;：空，＆＃34; com_branch_ig＆＃34;：空} ......
我想阅读此 JSON 行，但因为它以 JSONArray 开头，所以我很困惑。

我需要获得所有数据值。这是我的代码
private void makeJsonArrayRequest() {
showpDialog();
JsonArrayRequest req = new JsonArrayRequest(urlJsonArry,
new Response.Listener<JSONArray>() {
@Override
public void onResponse(JSONArray response) {
Log.d("res", response.toString());
try {
jsonResponse = "";
for (int i = 0; i < response.length(); i++) {
JSONObject branchi = (JSONObject) response.get(i);
JSONObject branch = branchi.getJSONObject("datas");
Integer com_branch_id = Integer.valueOf(branch.getString("com_branch_id"));
Integer com_branch_comId = Integer.valueOf(branch.getString("com_branch_comId"));
String com_branch_name = branch.getString("com_branch_name");
String com_branch_manager = branch.getString("com_branch_manager");
String com_branch_addr = branch.getString("com_branch_addr");
String com_branch_region = branch.getString("com_branch_region");
String com_branch_state = branch.getString("com_branch_state");
String com_branch_country = branch.getString("com_branch_country");
String com_branch_poscode = branch.getString("com_branch_poscode");
String com_branch_email = branch.getString("com_branch_email");
String com_branch_licence = branch.getString("com_branch_licence");
String com_branch_phoneNum = branch.getString("com_branch_phoneNum");
String com_branch_fax = branch.getString("datas.com_branch_fax");
String com_branch_fb = branch.getString("datas.com_branch_fb");
String com_branch_ig = branch.getString("datas.com_branch_ig");
jsonResponse = "";
jsonResponse += "Branch name: " + com_branch_id + "\n\n";
jsonResponse += "Branch manager: " + com_branch_comId + "\n\n";
jsonResponse += "Branch state: " + com_branch_name + "\n\n";
jsonResponse += "Branch state: " + com_branch_manager + "\n\n";
jsonResponse += "Branch state: " + com_branch_addr + "\n\n";
jsonResponse += "Branch state: " + com_branch_region + "\n\n";
jsonResponse += "Branch state: " + com_branch_state + "\n\n";
jsonResponse += "Branch state: " + com_branch_country + "\n\n";
jsonResponse += "Branch state: " + com_branch_poscode + "\n\n";
jsonResponse += "Branch state: " + com_branch_email + "\n\n";
jsonResponse += "Branch state: " + com_branch_licence + "\n\n";
jsonResponse += "Branch state: " + com_branch_phoneNum + "\n\n";
jsonResponse += "Branch state: " + com_branch_fax + "\n\n";
jsonResponse += "Branch state: " + com_branch_fb + "\n\n";
jsonResponse += "Branch state: " + com_branch_ig + "\n\n";
}
txtResponse.setText(jsonResponse);
} catch (JSONException e) {
e.printStackTrace();
Toast.makeText(getApplicationContext(),
"res" + e.getMessage(),
Toast.LENGTH_LONG).show();
txtResponse.setText(e.getMessage());
}
hidepDialog();
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
VolleyLog.d(TAG, "res" + error.getMessage());
Toast.makeText(getApplicationContext(),
error.getMessage(), Toast.LENGTH_LONG).show();
Log.d("onErrorResponse", error.getMessage());
hidepDialog();
}
});
// Adding request to request queue
AppController.getInstance().addToRequestQueue(req);
}
我尝试遵循其他解决方案但不幸的是我失败并陷入困境。

试试这个..
JSONObject json = new JSONObject(response);
JSONArray jsonarray = json.getJSONArray("datas");
for (int i = 0; i < jsonarray.length(); i++) {
JSONObject c = jsonarray.getJSONObject(i);
//here you get by json key
String id = c.getString("com_branch_id");
}

1）你的Json不是一个数组（它以{暗示一个对象开头} JSON）。使用JsonObjectRequest 2）而不是抓住元素， 在您的回复中，通过迭代，您可以使用jackson2来映射 回应你的POJO 3）您可以使用jsonschema2pojo创建一个 POJO班
答案 2 :(得分：0)
JsonArrayRequest会以JSONArray给您回复。但您的回答不是JSONArray。其JSONObject和JSONObject包含JSONArray。
根据您的情况使用JsonObjectRequest。
您可以使用Gson将响应转换为Java对象。
创建与您的响应格式匹配的Java Pojo类。将您的响应转换为java对象。
public void onResponse(JSONObject response) {
String message = "";
if (response != null) {
message = response.toString();
Post post = null;
Gson gson = new Gson();
post = gson.fromJson(response.toString(), Post.class);
} else {
message = "Response is null";
}
}
