I am working in Spinner.. I am having three spinners and i am going to display days (i,e) 1,2,3,4,5...30,31 in 1st spinner and months in 2nd spinner (i,e)1,2,3,...11,12 and Year in 3rd spinner 2010,.... What i want is that that i wanna to display current date,month,year in 1st,2nd,3rd spinner resp when the page loads..from that it is possible to select any day,month,Year
Here is my code::
public class NoteEdit extends Activity implements OnItemSelectedListener {

cal.set(Calendar.YEAR,year);
int noOfDayInMonthyear = cal.getActualMaximum(Calendar.DAY_OF_MONTH);
Log.v("noOfDayInMonthyear",""+noOfDayInMonthyear);
ArrayList<Integer> obj=new ArrayList();

if i understand your question right, i think you're asking how to set the value for each spinner?
figure out what value you want to select for each spinner and do something like this for each
http://developer.android.com/reference/android/widget/AbsSpinner.html#setSelection(int, boolean)
int dateId = <date id in the spinner>;
s2.setSelection(dateId);

Here is complete code
(In first activity two values are taken from spinner and through a function data sent to second activity)
First Activity:
public class FindBloodActivity extends AppCompatActivity {
String API = "http://abdolqadir-001-site1.ctempurl.com/Account.svc";
TextView t;
Spinner spbgid;
Spinner spcityid;
ProgressBar pro;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_find_blood);
t = (TextView) findViewById(R.id.tv);
pro=(ProgressBar) findViewById(R.id.progressBar2);
pro.setVisibility(View.INVISIBLE);
spbgid=(Spinner) findViewById(R.id.spinnerBG);
spcityid=(Spinner) findViewById(R.id.spinnerLocation);
t.setVisibility(View.INVISIBLE);
}
public void SearchOn(View v) {
String BGId = Integer.toString(spbgid.getSelectedItemPosition()+1);
String CityId =Integer.toString(spcityid.getSelectedItemPosition()+1);
Intent intent=new Intent(getApplicationContext(),SearchResult2.class);
intent.putExtra("bid",BGId);
intent.putExtra("cid",CityId);
startActivity(intent);
}
}
Second Activity: In second activity on tt.append(string.toString()); working fine, but when i add below code than application terminated if i try to debug than also application terminate.
public class SearchResult2 extends AppCompatActivity {

setContentView(R.layout.activity_search_result2);
tt=(TextView)findViewById(R.id.tvTest);
tt.setVisibility(View.INVISIBLE);
Bundle extras = getIntent().getExtras();
String BGId = extras.getString("bid");
String CityId = extras.getString("cid");
tt.setText("");
final RestAdapter restAdapter = new RestAdapter.Builder()
.setEndpoint(API).build();
final gitapi git = restAdapter.create(gitapi.class);
git.SearchUsers(BGId, CityId, new Callback<String>() {
#Override
public void success(String string, Response response) {
tt.append(string.toString());
}
#Override
public void failure(RetrofitError retrofitError) {
tt.setText("No User Found");
}
});
String bigArray = tt.getText().toString();
listView = (ListView)findViewById(R.id.lvUsers);
bigArray = bigArray.substring(0, bigArray.length() - 1);
totalUsersCount = bigArray.split(",").length;
listView.clearTextFilter();
if (totalUsersCount > 0)
{
String[] allUsers = new String[totalUsersCount];
allUsers = bigArray.split(",");
allUserNames = new String[totalUsersCount];
allUserContacts = new String[totalUsersCount];
String[] temp = new String[3];
for (int i = 0; i < totalUsersCount; i++) {
temp = allUsers[i].split("-");
allUserNames[i] = temp[1];
allUserContacts[i] = temp[2];
}
ArrayAdapter<String> itemsAdapter =
new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, allUserNames);
listView.setAdapter(itemsAdapter);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
SendSMS(position);
}
});
}
}
}

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {

}
});
}
}
Here are the things you can try, use this code in onCreate()
listView = (ListView)findViewById(R.id.lvUsers);
ArrayAdapter<String> itemsAdapter =
new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, allUserNames);
listView.setAdapter(itemsAdapter);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
SendSMS(position);
}
});
and where you were using the above code before replace it with i.e of inside of if condition
itemsAdapter.notifyDatasetChanged();
Hope this helps
Why not do your REST call from the onCreate() method?
Also component.setVisibility(View.INVISIBLE); retains space in the overall layout. You could use 'GONE' instead and see if that helps or hurts.
And try have your URL and other components in different methods or classes. This can help a WHOLE LOT to keep the code clean and easy to find errors.
With all this said, after using breakpoints and running in debug mode which line is the error?
I have some items (strings) in my spinner and when I select one of these items, I want back an associated value, for example:
If I select SAE 1020, it returns me 250.0
If I select E-155, it returns me 300.0
The value is suposed to be shown in a EditText, but the only value I see is 250.0.
After all, this value should be sent to the next Activity (I also do not know if I'm doing the transfer correctly).
What is happening? What can I do?
Code:
package com.mateus.ligacoestubulares;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.ArrayAdapter;

}
public double choiceM(String str) {
Double f1 = 0.0;
if (str.equals(AçoMontante[0])) {
f1 = 250.0;
} else if (str.equals(AçoMontante[1])) {
f1 = 300.0;
}
return f1;
}
public double choiceB(String str) {
Double fo = 0.0;
if (str.equals(AçoMontante[0])) {
fo = 250.0;
} else if (str.equals(AçoMontante[1])) {
fo = 300.0;
}
return fo;
}
}
Try this. This code is working as you want it to.
String [] AçoMontante = {"SAE 1020", "E-155"};

spinnerMont.setAdapter(arrayAdapter1);
spinnerBanzo.setAdapter(arrayAdapter2);
spinnerMont.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int i, long l) {
montStr = (String) parent.getItemAtPosition(i);
if(montStr == "SAE 1020"){
f1 = "250.0";
}
else if (montStr == "E-155"){
f1 = "300.0";
}
else{}
campoFy1.setText(f1);
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
}
});
spinnerBanzo.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int i, long l) {
banzoStr = (String) parent.getItemAtPosition(i);
if(banzoStr == "SAE 1020"){
fo = "250.0";
}
else if (banzoStr == "E-155"){
fo = "300.0";
}
else{}
campoFyo.setText(fo);
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
}
});
next = (Button) findViewById(R.id.prosseguir);
intentNext = new Intent(MainActivity.this, Second.class);
next.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String resistenciaM = campoFy1.getText().toString();
String resistenciaB = campoFyo.getText().toString();
bundle.putString("fy1",resistenciaM);
bundle.putString("fyo",resistenciaB);
intentNext.putExtras(bundle);
startActivity(intentNext);
}
});
}
Also, instead of bundles, you can just use private static variables to pass the value.
set f1 and fo as
private static String f1,fo; instead of String f1,fo;.
And call them in another activity as Dados.f1 or Dados.fo [ Dados here is your current activity ]

Desired outcome: when a user selects a subject called "Math", it should show all the math marks in list view according to the mark_name.
When the user chooses nothing, it should leave it blank.
Begin by creating an inner class that implements AdapterView.OnItemSelectedListener. Override it's two methods:
onItemSelected( )
Callback method to be invoked when an item in this
view has been selected.
onNothingSelected( )
Callback method to be invoked when the selection disappears from this view.
Now, set an object of this class as the listener on your spinner. Something like:
spinner.setOnItemSelectedListener( new MyItemSelectedListener() );
Now go back and provide a proper definition to those two methods.
hi how is fetching data from database and setting it in spinner on android app.how can i develop dis.the below code is update data from spinner to android mysql database.but i wish to need fetch the data from database and that fetched value is display on my spinner value on android app.how can i develop this..
this is my android code:
public class InsertionExample extends Activity {
private final String NAMESPACE = "http://xcart.com";
private final String URL = "http://192.168.1.168:8089/XcartLogin/services/update?wsdl";
private final String SOAP_ACTION = "http://xcart.com/insertData";
private final String METHOD_NAME = "insertData";
Button btninsert;
String selectedItem;
static final String KEY_NAME = "orderid";
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.change_status);
/* Intent in = getIntent();
// Get XML values from previous intent
String orderid = in.getStringExtra(KEY_NAME);
// Displaying all values on the screen
TextView lblName = (TextView) findViewById(R.id.textView1);
lblName.setText(orderid); */
Spinner spinner = (Spinner) findViewById(R.id.spinner1);
btninsert = (Button)findViewById(R.id.btn_insert1);
btninsert.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent in = getIntent();
String orderid = in.getStringExtra(KEY_NAME);
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
PropertyInfo unameProp =new PropertyInfo();
unameProp.setName("Status");//Define the variable name in the web service method
unameProp.setValue(selectedItem);//Define value for fname variable
unameProp.setType(String.class);//Define the type of the variable
request.addProperty(unameProp);
PropertyInfo idProp =new PropertyInfo();
idProp.setName("Orderid");//Define the variable name in the web service method
idProp.setValue(orderid);//Define value for fname variable
idProp.setType(String.class);//Define the type of the variable
request.addProperty(idProp);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.setOutputSoapObject(request);
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
try{
androidHttpTransport.call(SOAP_ACTION, envelope);
SoapPrimitive response = (SoapPrimitive)envelope.getResponse();
TextView result = (TextView) findViewById(R.id.textView2);
result.setText(response.toString());
}
catch(Exception e){
}
}
});
//attach the listener to the spinner
spinner.setOnItemSelectedListener(new MyOnItemSelectedListener());
//Dynamically generate a spinner data
createSpinnerDropDown();
}
//Add animals into spinner dynamically
private void createSpinnerDropDown() {
//get reference to the spinner from the XML layout
Spinner spinner = (Spinner) findViewById(R.id.spinner1);
//Array list of animals to display in the spinner
List<String> list = new ArrayList<String>();
list.add("Q");
list.add("P");
list.add("F");
list.add("I");
list.add("C");
//create an ArrayAdaptar from the String Array
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
android.R.layout.simple_spinner_item, list);
//set the view for the Drop down list
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
//set the ArrayAdapter to the spinner
spinner.setAdapter(adapter);
adapter.notifyDataSetChanged();
//attach the listener to the spinner
spinner.setOnItemSelectedListener(new MyOnItemSelectedListener());
}
public class MyOnItemSelectedListener implements OnItemSelectedListener {
public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {
selectedItem = parent.getItemAtPosition(pos).toString();
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
}
public void onNothingSelected(AdapterView<?> parent) {
// Do nothing.
}
}
please help me..how can i develop this.
Have you tried using ArrayAdapter<?> on your spinner? I used this once.
private class ColorSpinner extends ArrayAdapter<Integer> {
public ColorSpinner(Context context, int textViewResourceId) {
super(context, textViewResourceId);
}
#Override
public View getDropDownView(int position, View convertView, ViewGroup parent) {
return this.getView(position, convertView, parent);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
// Here can I set a custom layout or view of each item in the spinner.
TextView textView = new TextView(PincodeTextView.this.context);
String message = Integer.toHexString(this.getItem(position)).toUpperCase();
textView.setBackgroundColor(this.getItem(position));
textView.setText("0x" + message);
return textView;
}
}
Then I used this to load the spinner with my ColorSpinner:
final View colorbox = this.findViewById(R.id.edit_cell_dialog_color);
if (colorbox instanceof Spinner) {
ColorSpinner list = new ColorSpinner(context, android.R.layout.simple_spinner_item);
// Load from my database the need items in my case a list of color codes.
int[] colors = PincodeTextView.this.pincodeDB.getColors();
int indexOfColor = 0;
// Add each item into the Spinner.
for (int i = 0; i < colors.length; i++) {
list.add(colors[i]);
}
((Spinner) colorbox).setAdapter(list);
}
