problem with Spinner value

Question

\\this is my register.java code:

`public class Register extends Activity {

TextView ET_DEPARTMENT;

Spinner ET_TYPE;

EditText ET_NAME,ET_USER_NAME,ET_USER_PASS,ET_MOBILE,ET_PIN;

String name,type,user_name,user_pass,department,mobile,pin;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.register_layout);

ET_NAME=(EditText)findViewById(R.id.name);

final Spinner ET_TYPE= (Spinner)findViewById(R.id.automobileSpinner);

ET_USER_NAME=(EditText)findViewById(R.id.new_user_name);

ET_USER_PASS=(EditText)findViewById(R.id.new_user_pass);

ET_DEPARTMENT=(TextView)findViewById(R.id.RegistrationForm);

ET_MOBILE=(EditText)findViewById(R.id.user_mobile);

ET_PIN=(EditText)findViewById(R.id.user_pin);

}

public void userReg(View view)

{

name=ET_NAME.getText().toString();

type=ET_TYPE.getSelectedItem().toString();

user_name=ET_USER_NAME.getText().toString();

user_pass=ET_USER_PASS.getText().toString();

department=ET_DEPARTMENT.getText().toString();

mobile=ET_MOBILE.getText().toString();

pin=ET_PIN.getText().toString();

String method="register";

BackgroundTask backgroundTask=new BackgroundTask(this);

backgroundTask.execute(method,name,user_name,user_pass,department,mobile,pin);

finish();

}

}

this is my backgroundTask.java code:

enter code here

public class BackgroundTask extends AsyncTask<String,Void,String> {

Context ctx;

BackgroundTask(Context ctx)

{

this.ctx=ctx;

}

@Override

protected void onPreExecute() {

super.onPreExecute();

}

@Override

protected String doInBackground(String... params) {

String reg_url="http://10.0.2.2/handy/register.php";

String method=params[0];

if (method.equals("register"))

{

String name=params[1];

String user_name=params[2];

String user_pass=params[3];

String department=params[4];

String mobile=params[5];

String pin=params[6];

String type=params[7];

try {

URL url=new URL(reg_url);

HttpURLConnection httpURLConnection=(HttpURLConnection)url.openConnection();

httpURLConnection.setRequestMethod("POST");

httpURLConnection.setDoOutput(true);

OutputStream OS=httpURLConnection.getOutputStream();

BufferedWriter bufferedWriter=new BufferedWriter(new OutputStreamWriter(OS,"UTF-8"));

String data= URLEncoder.encode("user","UTF-8") +"="+URLEncoder.encode(name,"UTF-8")+"&"+

URLEncoder.encode("user_name","UTF-8") +"="+URLEncoder.encode(user_name,"UTF-8")+"&"+

URLEncoder.encode("user_pass","UTF-8") +"="+URLEncoder.encode(user_pass,"UTF-8")+"&"+

URLEncoder.encode("department","UTF-8") +"="+URLEncoder.encode(department,"UTF-8")+"&"+

URLEncoder.encode("mobile","UTF-8") +"="+URLEncoder.encode(mobile,"UTF-8")+"&"+

URLEncoder.encode("pin","UTF-8") +"="+URLEncoder.encode(pin,"UTF-8")+"&"+

URLEncoder.encode("type","UTF-8") +"="+ URLEncoder.encode(type,"UTF-8");

bufferedWriter.write(data);

bufferedWriter.flush();

bufferedWriter.close();

OS.close();

InputStream IS=httpURLConnection.getInputStream();

IS.close();

return "Registration Success...";

} catch (MalformedURLException e) {

e.printStackTrace();

} catch (IOException e) {

e.printStackTrace();

}

}

return null;

}

@Override

protected void onProgressUpdate(Void... values) {

super.onProgressUpdate(values);

}

@Override

protected void onPostExecute(String result) {

Toast.makeText(ctx,result,Toast.LENGTH_LONG).show();

}

}
