This code is not reading the value from the spinner it's reading only the first value always,
btnResult.setOnClickListener(new View.OnClickListener()
{
final String USN = spnConversions.getSelectedItem().toString();
#Override
public void onClick(View v)
{
Intent i = new Intent(getApplicationContext(), DatabaseResult.class);
i.putExtra("getData",USN.toString());
startActivity(i);
}
});
Why you are using onClickListener for Spinner ? You should use OnItemSelectedListener() for Spinner see the below example code,
public class MySpinnerSelectedListener implements OnItemSelectedListener {
public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {
String selected = parent.getItemAtPosition(pos).toString();
}
public void onNothingSelected(AdapterView parent) {
// Do nothing.
}
}
Now register listener using following code,
spinner.setOnItemSelectedListener(new MySpinnerSelectedListener());
You can pass it using following code,
// Sending Code
Intent intent = new Intent(getApplicationContext(), DatabaseResult.class);
intent.putextra("getData",USN.toString());
startActivity(intent);
// Receiving code,
String value= getIntent().getStringExtra("getData");
public class SpinnerExample extends Activity
{
Spinner sp;
String text ="";
Button btnResult;
public void onCreate(Bundle savedInstanceState)
{
sp = (Spinner) findViewById(R.id.spinner1);
sp.setOnItemSelectedListener(new OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> parent, View arg1, int arg2, long arg3)
{
this.text = parent.getItemAtPosition(pos).toString();
}
public void onNothingSelected(AdapterView<?> arg0)
{
/ TODO Auto-generated method stub
}
});
btnResult = (Button) findViewById(R.id.buttonId);
btnResult.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
Intent i = new Intent(getApplicationContext(), DatabaseResult.class);
i.putExtra("getData",this.text);
startActivity(i);
}
});
}
}
try this
int positionitem = spinner.getSelectedItemPosition();

I'm trying to get the position (number) of the spinner when selected to use it in another Activity that will display a different map each time depending on the item selected. when I run the application it crashes. this is the first Activity code:
public class TestProjectActivity extends Activity {
public Spinner spinner1;
public Integer number;
private Button valideButton;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
MySpinner();
valide_button();
}
public void MySpinner() {
final Spinner spinner1 = (Spinner) findViewById(R.id.spinner1);
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(
this, R.array.num, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner1.setAdapter(adapter);
spinner1.setOnItemSelectedListener(new OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> parentView,
View selectedItemView, int position, long id) {
// Object item = parentView.getItemAtPosition(position);
TestProjectActivity.this.number = spinner1
.getSelectedItemPosition() + 1;
}
public void onNothingSelected(AdapterView<?> arg0) {// do nothing
}
});
}
public void valide_button() {
valideButton = (Button) findViewById(R.id.valide_button);
valideButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent intent = new Intent(TestProjectActivity.this,
MetroMapActivity.class);
startActivity(intent);
}
});
}
}
The way to get the selection of the spinner is:
spinner1.getSelectedItemPosition();
Documentation reference:
http://developer.android.com/reference/android/widget/AdapterView.html#getSelectedItemPosition()
However, in your code, the one place you are referencing it is within your setOnItemSelectedListener(). It is not necessary to poll the spinner, because the onItemSelected method gets passed the position as the "position" variable.
So you could change that line to:
TestProjectActivity.this.number = position + 1;
If that does not fix the problem, please post the error message generated when your app crashes.
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
bt = findViewById(R.id.button);
spinner = findViewById(R.id.sp_item);
setInfo();
spinnerAdapter = new SpinnerAdapter(this, arrayList);
spinner.setAdapter(spinnerAdapter);
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
//first, we have to retrieve the item position as a string
// then, we can change string value into integer
String item_position = String.valueOf(position);
int positonInt = Integer.valueOf(item_position);
Toast.makeText(MainActivity.this, "value is "+ positonInt, Toast.LENGTH_SHORT).show();
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
note: the position of items is counted from 0.
final int[] positions=new int[2];
Spinner sp=findViewByID(R.id.spinner);
sp.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
// TODO Auto-generated method stub
Toast.makeText( arg2....);
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
if (position ==0) {
if (rYes.isChecked()) {
Toast.makeText(SportActivity.this, "yes ur answer is right", Toast.LENGTH_LONG).show();
} else if (rNo.isChecked()) {
Toast.makeText(SportActivity.this, "no.ur answer is wrong", Toast.LENGTH_LONG).show();
}
}
This code is supposed to select both check boxes.
Is there a problem with it?
i want to take the value in spinner and user press the ok Button and then start new activity from against the value of spinner. The string array is just like that.
public class Menu extends Activity implements View.OnClickListener {
private String[] array_spinner = {"Select Here", "Honda", "Toyota", "Mitibushi"};
private String[] array_spinner01 = {"Select Here", "Civic", "Gli", "Lancer"};
// //private String[] array_spinner02={"1999","2000","2005"};
// Spinner s,s1,s2;
// Button ok;
//#Override
// protected void onCreate(Bundle savedInstanceState) {
// super.onCreate(savedInstanceState);
Spinner s, s1;
Button ok;
Object _globalString;
Object _globalString2;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_menu);
s = (Spinner) findViewById(R.id.spinner);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(getApplicationContext(), android.R.layout.simple_spinner_dropdown_item, array_spinner);
s.setAdapter(adapter);
s1 = (Spinner) findViewById(R.id.spinner01);
ArrayAdapter<String> adapter1 = new ArrayAdapter<String>(getApplicationContext(), android.R.layout.simple_spinner_dropdown_item, array_spinner01);
s1.setAdapter(adapter1);
//
// s2=(Spinner)findViewById(R.id.spinner02);
// ArrayAdapter<String> adapter2=new ArrayAdapter<String>(getApplicationContext(),android.R.layout.simple_spinner_dropdown_item,array_spinner02);
// s2.setAdapter(adapter2);
ok = (Button) findViewById(R.id.btn_ok);
ok.setOnClickListener(this);
s.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
_globalString = parent.getItemAtPosition(position);
}
//#Override
public void onNothingSelected(AdapterView<?> parent) {
// TODO Auto-generated method stub
}
});
s1.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
_globalString2 = parent.getItemAtPosition(position);
}
// #Override
public void onNothingSelected(AdapterView<?> parent) {
// TODO Auto-generated method stub
}
});
}
#Override
public void onClick(View v) {
if (v.getId() == R.id.btn_ok) {
if (_globalString.equals("Honda") || _globalString2.equals("Civic")) {
startActivity(new Intent(getApplicationContext(), Civic.class));
} else if (_globalString.equals("Toyota") || _globalString2.equals("Gli")) {
startActivity(new Intent(getApplicationContext(), Toyota.class));
}
}
}
}
please tell me where is my mistake in this code because i stucked and i cant find it
There are many ways to do this, but I would recommend to follow these solution :
First :
save the value of the spinner in a global string variable by declaring a string at the top of your Activity like below :
public class Menu extends Activity implements View.OnClickListener {
Spinner s1, s2;
Button acceptbutton;
String _globalString ;
String _globalString2 ;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//Your code ..
Now you need to save the value of your selected field into that string, everytime your spinner changes value :
s1.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view,
int position, long id) {
_globalString = parent.getItemAtPosition(position);
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
// TODO Auto-generated method stub
}
});
s.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view,
int position, long id) {
_globalString2 = parent.getItemAtPosition(position);
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
// TODO Auto-generated method stub
}
});
Now you can switch activity based on spinner value :
#Override
public void onClick(View v) {
if (v.getId() == R.id.btn_ok) {
if (_globalString.equals("Honda") || _globalString2.equals("Civic")) {
startActivity(new Intent(getApplicationContext(), Civic.class));
} else if (_globalString.equals("Toyota") || _globalString2.equals("Gli")) {
startActivity(new Intent(getApplicationContext(), Toyota.class));
}
}
}
Im using a spinner and i was wondering how can you get an item from the spinner to appear in an image button the images are using string as value.
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_up);
spinnerListener();
St = (Spinner) findViewById(R.id.Namess);
imageButton01 = (ImageButton) findViewById(R.id.ImageButton1);
}
private void spinnerListener() {
ArrayList<Name> players = List_content.ENTRY_LIST_PLAYERS;
final ArrayAdapter<String> adapter=new ArrayAdapter<String>(Line_up.this, android.R.layout.simple_spinner_item);
{for (Name p : players){adapter.add(p.f_name);}};
playerss.setAdapter(adapter);
playerss.setOnItemSelectedListener(new OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> av, View v,
int position, long itemId) {
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
// TODO Auto-generated method stub
}
});
}
public void goalkeeper(View v){
st.performClick();
}
OK. Here's the trick:
When ImageButton is clicked, you just need to call performClick() on the spinner object.
int[] pictureIds = {
R.drawable.picture1,
//add as many picture IDs as you want
R.drawable.picture2
}
imageButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
spinner.performClick();
}
});
spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> arg0, View arg1,
int position, long arg3) {
imageButton.setImageResource(pictureIds[position]);
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
Don't forget to set spinner adapter just as you did correctly in your question.

Is there a problem with it?
I wanted to ask how can one use both spinner and button on the same activity. Spinner listens with its onItemListener and then the button would have an onClick listener too. So in my case, it generates an error. My scenario is that I get the selected string from the spinner and then the rest of the values from editTexts and then hit "submit" to send data to the server. But I reckon these two listeners aren't very friendly with each other?
I set up these methods for the spinner right:
spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) {
// your code here
}
#Override
public void onNothingSelected(AdapterView<?> parentView) {
// your code here
}
});
Then I need to put the onclick listener for the button:
go.setOnClickListener(new OnClickListener(){
public void onClick(View arg0)
{
}
Where do I put this one? Before the nothingSelected method or after that?
I think they are very friendly with each other :)
spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) {
// your code here
}
#Override
public void onNothingSelected(AdapterView<?> parentView) {
// your code here
}
});
go.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
// your code here
}
});
public class StackOverflowActivity extends Activity {
private static final String[] SPINNER_DATA = new String[] { "Item 1", "Item 2" };
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Spinner spn = (Spinner) findViewById(R.id.spinner1);
spn.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_dropdown_item_1line, SPINNER_DATA));
spn.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(),
"Spinner.onItemSelected()", Toast.LENGTH_LONG).show();
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(),
"Spinner.onNothingSelected()", Toast.LENGTH_LONG)
.show();
}
});
Button btn = (Button) findViewById(R.id.button1);
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(), "Button.onClick()",
Toast.LENGTH_LONG).show();
}
});
}
}
