In my Android app I am loading json data with a Volley JsonArrayRequest
. The data were created by myself and I saved them with Sublime with UTF-8 encoding. When I get the Response
and fill my ListView
, the texts are not displayed correctly (umlauts). This is what my Request looks like:
JsonArrayRequest request = new JsonArrayRequest(targetUrl,
new Response.Listener<JSONArray>() {
@Override
public void onResponse(final JSONArray response) {
try {
fillList(response);
} catch (JSONException e) {
e.printStackTrace();
}
}
},
new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
}
});
requestQueue.add(request);
When I load the exact same data with this method, all texts are displayed correctly:
final StringBuilder builder = new StringBuilder();
final HttpClient client = new DefaultHttpClient();
final HttpGet httpGet = new HttpGet(request);
try {
final HttpResponse response = client.execute(httpGet);
final StatusLine statusLine = response.getStatusLine();
int statusCode = statusLine.getStatusCode();
if (statusCode == 200) {
final HttpEntity entity = response.getEntity();
final InputStream content = entity.getContent();
final BufferedReader reader = new BufferedReader(new InputStreamReader(content));
String line;
while ((line = reader.readLine()) != null) {
builder.append(line);
}
} else {
}
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
So to me it seems like there is no problem with the encoding of my json file. How can I fix this encoding problem in Volley?
If you know that absolutely all of the files you are requesting will be in the UTF-8 format, which it sounds like you do, then you might consider forcing your Volley request to return UTF-8 formatted strings. You could accomplish this by subclassing the standard JSON request. Something like this:
public class Utf8JsonRequest extends JsonRequest<JSONObject> {
...
@Override
protected Response<JSONObject> parseNetworkResponse (NetworkResponse response) {
try {
String utf8String = new String(response.data, "UTF-8");
return Response.success(new JSONObject(utf8String), HttpHeaderParser.parseCacheHeaders(response));
} catch (UnsupportedEncodingException e) {
// log error
return Response.error(new ParseError(e));
} catch (JSONException e) {
// log error
return Response.error(new ParseError(e));
}
}
}
I have same problem like this and i solve it using UTF-8 charset.
String str = "";
try {
str = new String(strFromService.getBytes("ISO-8859-1"), "UTF-8");
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
String decodedStr = Html.fromHtml(str).toString();
I hope this will work for you
