Spinner - How to get value? Android Studio

I would like to insert values from a form into my database. I had problems with values from spinners and I did something wrong, because when I intent in my next activity where the form is the app stops. I will be really grateful.
MainActivity.java
public class MainActivity extends AppCompatActivity {
EditText UsernameEt, PasswordEt;
private static Button btnLogin;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
UsernameEt = (EditText) findViewById(R.id.etUserName);
PasswordEt = (EditText) findViewById(R.id.etPassword);
OnClickButtonListener();
}
public void OnClickButtonListener() {
btnLogin = (Button) findViewById(R.id.btnLogin);
btnLogin.setOnClickListener(
new View.OnClickListener() {
public void onClick(View v) {
Intent intent = new Intent(".SecondPan");
startActivity(intent);
}
}
);
}
public void OnLogin(View view)
{
String username = UsernameEt.getText().toString();
String password = PasswordEt.getText().toString();
String type = "login";
BackgroundWorker backgroundWorker = new BackgroundWorker(this);
backgroundWorker.execute(type,username,password);
}
public void OpenReg(View view){
startActivity(new Intent(this,Register.class));
}
}
Second Panel where user should've been intented and where spinners are:
public class SecondPan extends AppCompatActivity implements AdapterView.OnItemClickListener {
private Spinner sspnOption6, sspn2;
private TextView ttxOption6, ttx;
EditText umowa,nazwa,kategorie,opis,zabezpieczenia,dane;
String czy_dane, transfer;
#SuppressLint("CutPasteId")
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_second_pan);
Spinner sspn2 = (Spinner)findViewById(R.id.sspn);
czy_dane = sspn2.getSelectedItem().toString();
Spinner sspnOption6 = (Spinner)findViewById(R.id.sspn2);
transfer = sspnOption6.getSelectedItem().toString();
umowa = (EditText) findViewById(R.id.scnd_txt1);
nazwa = (EditText) findViewById(R.id.scnd_txt2);
kategorie = (EditText) findViewById(R.id.scnd_txt3);
opis = (EditText) findViewById(R.id.scnd_tx4);
zabezpieczenia = (EditText) findViewById(R.id.scnd_tx6);
dane = (EditText) findViewById(R.id.scnd_tx7);
sspnOption6 = findViewById(R.id.sspn);
ArrayAdapter<CharSequence> FirstAdapter = ArrayAdapter.createFromResource(this, R.array.tab1, android.R.layout.simple_spinner_item);
FirstAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
sspn2=findViewById(R.id.sspn2);
ArrayAdapter<CharSequence> Secondadapter = ArrayAdapter.createFromResource(this, R.array.transfer, android.R.layout.simple_spinner_item);
Secondadapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
sspn2.setAdapter(Secondadapter);
}
public void onItemClick(AdapterView<?> parent, View view, int position, long l) {
String text = parent.getItemAtPosition(position).toString();
Toast.makeText(parent.getContext(), text, Toast.LENGTH_SHORT).show();
}
public void OnInsert(View view ) {
String str_czy_dane = sspn2.getSelectedItem().toString();
String str_umowa = umowa.getText().toString();
String str_nazwa = nazwa.getText().toString();
String str_kategorie = kategorie.getText().toString();
String str_opis = opis.getText().toString();
String str_transfer = sspn2.getSelectedItem().toString();
String str_zabezpieczenia = zabezpieczenia.getText().toString();
String str_dane = dane.getText().toString();
String type = "insert";
BackgroundWorker backgroundWorker = new BackgroundWorker(this);
backgroundWorker.execute(type, str_czy_dane,str_umowa, str_nazwa, str_kategorie, str_opis,str_transfer, str_zabezpieczenia, str_dane);
}
}
And there is a script to POST data:
BackgroundWorker.java
else if(type.equals("insert")){
try {
String umowa = params[1];
String czy_dane = params[2];
String nazwa = params[3];
String kategorie = params[4];
String opis = params[5];
String transfer = params[6];
String zabezpieczenia = params[7];
String dane = params[8];
URL url = new URL (insert_url);
HttpURLConnection httpURLConnection=(HttpURLConnection)url.openConnection();
httpURLConnection.setRequestMethod("POST");
httpURLConnection.setDoOutput(true);
httpURLConnection.setDoInput(true);
OutputStream outputStream = httpURLConnection.getOutputStream();
BufferedWriter bufferedWriter = new BufferedWriter(new OutputStreamWriter(outputStream,"UTF-8"));
String post_data = URLEncoder.encode("czy_dane","UTF-8")+"="+URLEncoder.encode(czy_dane,"UTF-8")+"&"+
URLEncoder.encode("umowa","UTF-8")+"="+URLEncoder.encode(umowa,"UTF-8")+"&"
+URLEncoder.encode("nazwa","UTF-8")+"="+URLEncoder.encode(nazwa,"UTF-8")+"&"
+URLEncoder.encode("kategorie","UTF-8")+"="+URLEncoder.encode(kategorie,"UTF-8")+"&"
+URLEncoder.encode("opis","UTF-8")+"="+URLEncoder.encode(opis,"UTF-8")+"&"

+URLEncoder.encode("zabezpieczenia","UTF-8")+"="+URLEncoder.encode(zabezpieczenia,"UTF-8")+"&"
+URLEncoder.encode("dane","UTF-8")+"="+URLEncoder.encode(dane,"UTF-8");
bufferedWriter.write(post_data);
bufferedWriter.flush();
bufferedWriter.close();
outputStream.close();
InputStream inputStream = httpURLConnection.getInputStream();
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream,"iso-8859-1")) ;
String result="";
String line="";
while((line = bufferedReader.readLine())!=null) {
result+= line;
}
bufferedReader.close();
inputStream.close();
httpURLConnection.disconnect();
return result;
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
return null;

In your code, you are twice assigning Spinner.
Spinner sspn2 = (Spinner)findViewById(R.id.sspn); /// FIRST SPINNER 1 time
czy_dane = sspn2.getSelectedItem().toString();
Spinner sspnOption6 = (Spinner)findViewById(R.id.sspn2);/// SECOND SPINNER 1 time
transfer = sspnOption6.getSelectedItem().toString();
umowa = (EditText) findViewById(R.id.scnd_txt1);
nazwa = (EditText) findViewById(R.id.scnd_txt2);
kategorie = (EditText) findViewById(R.id.scnd_txt3);
opis = (EditText) findViewById(R.id.scnd_tx4);
zabezpieczenia = (EditText) findViewById(R.id.scnd_tx6);
dane = (EditText) findViewById(R.id.scnd_tx7);
sspnOption6 = findViewById(R.id.sspn); /// FIRST SPINNER 2 time
ArrayAdapter<CharSequence> FirstAdapter = ArrayAdapter.createFromResource(this, R.array.tab1, android.R.layout.simple_spinner_item);
FirstAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
sspn2=findViewById(R.id.sspn2); /// SECOND SPINNER 2 time
ArrayAdapter<CharSequence> Secondadapter = ArrayAdapter.createFromResource(this, R.array.transfer, android.R.layout.simple_spinner_item);
Secondadapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
sspn2.setAdapter(Secondadapter);
SOLUTION:
Spinner sspn2 ;
Spinner sspnOption6 ;
umowa = (EditText) findViewById(R.id.scnd_txt1);
nazwa = (EditText) findViewById(R.id.scnd_txt2);
kategorie = (EditText) findViewById(R.id.scnd_txt3);
opis = (EditText) findViewById(R.id.scnd_tx4);
zabezpieczenia = (EditText) findViewById(R.id.scnd_tx6);
dane = (EditText) findViewById(R.id.scnd_tx7);
sspnOption6 = findViewById(R.id.sspn);
ArrayAdapter<CharSequence> FirstAdapter = new ArrayAdapter<CharSequence>(this,
android.R.layout.simple_spinner_item, getResources()
.getStringArray(R.array.tab1));
FirstAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
sspnOption6.setAdapter(FirstAdapter);
sspn2=findViewById(R.id.sspn2);
ArrayAdapter<CharSequence> Secondadapter = new ArrayAdapter<CharSequence>(this,
android.R.layout.simple_spinner_item, getResources()
.getStringArray(R.array.transfer));
Secondadapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
sspn2.setAdapter(Secondadapter);
czy_dane = sspn2.getSelectedItem().toString();
transfer = sspnOption6.getSelectedItem().toString();

Spinner is not populating with the data recieved from webservice

I am creating an android application for my client and in this app the user have to fill a form. I am using JSON web service for this purpose and I know how to send and receive data. Problem is that while I am fetching necessary data to fill the form and populating the spinner (I have multiple spinners in my form) the data doesn't populate to the spinner however I am successfully getting the data from web service. Please review my code and kindly help me because i don't have much time remaining. Thanks in advance.

I can't see your spinner in the xml file. But I had similar issue and was fixed when I added entries in my spinner in the xml. I had all my adapter and spinner items all right but wouldn't get displayed in the spinner without adding the entries in the xml file.

try to set the adapter to spinner after getting all values in list, debug your code and make sure your list has data in it before setting adapter to spinners.

The issue resolved successfully by just changing the spinner mode from dialog to dropdown
Previously
android:spinnerMode="dialog"
Now
android:spinnerMode="dropdown"
the previous xml is here

the correct xml is here

You forgot to commit the transaction.
database.setTransactionSuccessful();
database.endTransaction();

Activity with two JSONClasses

I have an activity that suppose to use JSON twice. In the first time it works perfectly, but on the second time it seems that the JSON class goes directly to the onPostExecute function without activating the doInBackground function. This is the activity that calls the JSON:
public class Registration extends ActionBarActivity {
public void regis(View view) {
EditText userName = (EditText) findViewById(R.id.userNameTxt);
EditText pass1 = (EditText) findViewById(R.id.PassTxt);
EditText pass2 = (EditText) findViewById(R.id.RePassTxt);
EditText displayName = (EditText) findViewById(R.id.DisplayTxt);
EditText mail = (EditText) findViewById(R.id.eMailTxt);
CheckBox agree = (CheckBox) findViewById(R.id.checkAgree);
TextView err = (TextView) findViewById(R.id.err);
String uName = userName.getText().toString(), pss1 = pass1.getText().toString(),
pss2 = pass2.getText().toString(), disName = displayName.getText().toString(),
eMail = mail.getText().toString();
if ((uName.length() > 0) && (pss1.length() > 0) && (pss2.length() > 0) && (disName.length() > 0)
&& (eMail.length() > 0)) {
if (pss1.equals(pss2)) {
if (agree.isChecked()) {
err.setVisibility(TextView.INVISIBLE);
String str = "?uname=" + uName;
new JSONClass(this, 2, str, this).execute();
} else {
err.setText("You must approve the use terms");
err.setVisibility(TextView.VISIBLE);
}
} else {
err.setText("The two passwords must match!");
err.setVisibility(TextView.VISIBLE);
}
} else {
err.setText("You must insert values in every cell");
err.setVisibility(TextView.VISIBLE);
}
}
public void checkExist(JSONArray ans) {
try {
int cnt = Integer.parseInt(ans.getJSONObject(0).getString("cnt"));
if (cnt == 1) {
TextView err = (TextView) findViewById(R.id.err);
err.setText("User name already exists!");
err.setVisibility(TextView.VISIBLE);
} else {
EditText userName = (EditText) findViewById(R.id.userNameTxt);
EditText pass = (EditText) findViewById(R.id.PassTxt);
EditText displayName = (EditText) findViewById(R.id.DisplayTxt);
EditText mail = (EditText) findViewById(R.id.eMailTxt);
String uName = userName.getText().toString(), pss = pass.getText().toString(),
disName = displayName.getText().toString(), eMail = mail.getText().toString();
SimpleDateFormat sdf = new SimpleDateFormat("HH:mm:ss yyyy-MM-dd");
String currentDateandTime = sdf.format(new Date());
String str = "?uname=" + uName + "&password=" + pss + "&email=" + eMail + "&disnam=" +
disName + "&dt=" + currentDateandTime;
Log.e("log_tag", "Just for me: " + str);
new JSONClass(this, 3, str, this).execute();
}
} catch (JSONException e) {
e.printStackTrace();
}
}
public void openLogin() {
Intent intent = new Intent(this, Login.class);
startActivity(intent);
finish();
}
}
I removed unnecessary functions. This is my JSON class:
public class JSONClass extends AsyncTask<String,Void,JSONArray>{
private String link;
private int flag;
private Login log = null;
private Registration reg = null;
private Context context;
public JSONClass(Context context, int queryNo, String params, Registration regg) {
this.context = context;
link = "http://pickupfriend.fulba.com/android_project/query" + queryNo + ".php" + params;
reg = regg;
flag = queryNo;
}
#TargetApi(Build.VERSION_CODES.KITKAT)
#Override
protected JSONArray doInBackground(String... arg0) {
JSONArray arr = new JSONArray();
try{
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost(link);
post.addHeader("Content-Type", "application/x-www-form-urlencoded");
HttpResponse response = client.execute(post);
HttpEntity entity = response.getEntity();
String result = EntityUtils.toString(entity, "utf-8");
arr = new JSONArray(result);
}catch(Exception e){
}
return arr;
}
#TargetApi(Build.VERSION_CODES.KITKAT)
public void onPostExecute(JSONArray result) {
switch (flag) {
case 1:
log.getResults(result);
break;
case 2:
reg.checkExist(result);
break;
case 3:
reg.openLogin();
break;
default:
break;
}
}
}
At first I activate the regis function that works perfectly with the json class. Afterwards it suppose to activate checkExist if the cnt parameter is 0, which is 0. Then it is suppose to activate the json class again but it seems that it goes directly to openLogin function without going to the php file and activating it. Am I doing something wrong?

Check duplicate editText before writing into .csv

I have several editText in my FirstActivity for CSV:
Button save;
CSV csv;
StringBuffer filePathc;
public final static String EXTRA_MESSAGE = "com.example.mapcard.MESSAGE";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_new_card);
txtName= (EditText) findViewById(R.id.txtName);
txtCompany= (EditText) findViewById(R.id.txtCompany);
txtPhone= (EditText) findViewById(R.id.txtPhone);
txtMobile = (EditText) findViewById(R.id.txtMobile);
txtAddress = (EditText) findViewById(R.id.txtAddress);
txtEmail = (EditText) findViewById(R.id.txtEmail);
txtWebsite = (EditText) findViewById(R.id.txtWebsite);
txtTitle = (EditText) findViewById(R.id.txtTitle);
filePathc = new StringBuffer();
filePathc.append("/sdcard/Android/data/");
file = new File(filePathc+filename.toString());
csv = new CSV(file);
save=(Button)findViewById(R.id.save);
save.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
csv.writeHeader(txtName.getText().toString()+ ","
+txtCompany.getText().toString()
+ "," +txtPhone.getText().toString()
+ "," +txtMobile.getText().toString()
+ "," +txtAddress.getText().toString()
+ "," +txtEmail.getText().toString()
+ "," +txtWebsite.getText().toString()
+ "," +txtTitle.getText().toString());
Intent intent = new Intent(NewCard.this, Template.class);
intent.putExtra("name", Name);
intent.putExtra("company", Company);
intent.putExtra("phone", Phone);
intent.putExtra("mobile", Mobile);
intent.putExtra("address", Address);
intent.putExtra("email", Email);
intent.putExtra("website", Website);
intent.putExtra("title", Title);
startActivity(intent);
SecondActivity is to write this data into .csv file:
public class CSV {
private PrintWriter csvWriter;
private File file;
public CSV(File file) {
this.file = file;
}
public void writeHeader(String data) {
try {
if (data != null) {
csvWriter = new PrintWriter(new FileWriter(file, true));
csvWriter.print("\r\n"+",");
csvWriter.print(data);
csvWriter.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}}
File in directory is successfully created and data is inserted. I am trying to check the data like Name or Email, if it is duplicate/already recorded to not save into .csv and warn user with Toast "same data".
I think it is something to do with line:
try {
if (data != null) {
Your helps and suggestions are appreciated. Thank you.

Use following function
public boolean exist(String newData){
try {
FileInputStream fIn = new FileInputStream(file);
BufferedReader myReader = new BufferedReader(
new InputStreamReader(fIn));
String aDataRow = "";
String aBuffer = "";
while ((aDataRow = myReader.readLine()) != null) {
if(aDataRow.contains(newData))//<--check if data exists
return true;
}
txtData.setText(aBuffer);
myReader.close();
} catch (Exception e) {
}
return false;
}
And change your write header function to:
public void writeHeader(String data) {
try {
if (data != null&&!data.isEmpty()&&!exist(data)) {
csvWriter = new PrintWriter(new FileWriter(file, true));
csvWriter.print("\r\n"+",");
csvWriter.print(data);
csvWriter.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}

data != null doesnt cover the case that the String is just empty, but not null. So basically you get "" from the textview by calling getText(). adding && !"".equals(data) should fix that problem
UPDATE
Well, there is a difference between an empty, and an uninitalized String. An uninitalized String means you declared it like String a; but nothing further.
If you use editText.getText() the editText will return a String which has been initialized but contains only what is currently in it. So basically if there is nothing in the editext it will return "".
And to sum this up:
String a;
null == "" // false
a == null // true
"".equals(editText.getTExt()) // true if the editext doesnt contain anything
