удачи
е извлекаются из базы данных mysql, и они не отображаются на счетчике, но отображаются в раскрывающемся списке. Не знаю, в чем проблема ..
вот мне полный код: -
main.java
public class MainActivity extends AppCompatActivity {
ArrayList<String> listItems = new ArrayList<>();
Spinner spn;
ArrayAdapter<String> adapter;
ProgressDialog mProgressDialog;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
spn= (Spinner)findViewById(R.id.selectcmpny);
adapter = new ArrayAdapter<String>(getApplicationContext(), R.layout.spinner_layout, R.id.txt1,listItems);
spn.setAdapter(adapter);
adapter.notifyDataSetChanged();
// spn.setSelection(0);
}
public void onStart() {
super.onStart();
BackTask bt = new BackTask();
bt.execute();
}
//for Spinner
private class BackTask extends AsyncTask<Void, Void, Void> {
ArrayList<String> list;
@Override
protected void onPreExecute() {
super.onPreExecute();
list = new ArrayList<>();
}
protected Void doInBackground(Void... params) {
InputStream is = null;
String result = "";
try {
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://www.abcdefg.com/o_cmpany.php");
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
// Get our response as a String.
is = entity.getContent();
} catch (IOException e) {
e.printStackTrace();
}
//convert response to string
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(is, "utf-8"));
String line = null;
while ((line = reader.readLine()) != null) {
result += line;
}
is.close();
//result=sb.toString();
} catch (Exception e) {
e.printStackTrace();
}
// parse json data
try {
JSONArray jArray = new JSONArray(result);
list.add("Please Select Company");
for (int i = 0; i < jArray.length(); i++) {
JSONObject jsonObject = jArray.getJSONObject(i);
// add interviewee name to arraylist
list.add(jsonObject.getString("name"));
}
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
protected void onPostExecute(Void result) {
listItems.addAll(list);
}
}
}
