On Spinner item click
mSpinnerCountry.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view,
int position, long id) {
// TODO Auto-generated method stub
mStringCountryID=mArrayListCountryDatas.get(position).getId();
mSpinnerCountry.setPrompt(mArrayListCountryDatas.get(position).getIso_alpha()+"
}
#Override
public void onNothingSelected(AdapterView<?> parent) {

}
});
When i run above code it is not set value any idea how can i make it possible ?

mSpinnerCountry.setOnItemSelectedListener(new OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
int mStringCountryID = s1.getSelectedItemPosition(); Toast.makeText(getBaseContext(),
"You have selected item : " + presidents[mStringCountryID],
Toast.LENGTH_SHORT).show();
}
public void onNothingSelected(AdapterView<?> arg0) {
}
});
Try this... variable mStringCountryID will hold your specific complete value do what ever you want to do with this value.

Display EditText items on Spinner selection

I have a group of items in spinner and on their click I want to show the respective text in EditText . How I can achieve this. I thought of using switch but it doesnot work for strings. I want someone to tell me right approach for doing this.
I want the EditText array(mysuburb) to respond accordingly to the Spinner items(mystate) click .
Code:-
String[] mysuburb =new String[]{"sub1" ,"sub2","sub3","sub4","sub5","sub6"};
String[] mystate= new String[]{"NSW","Victoria","Qld","NT","WA","SA"};
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this.getActivity(), R.layout.listrow, mystate);
// LTRadapter.setDropDownViewResource(android.R.layout.simple_dropdown_item_1line);
state.setAdapter(adapter);
state.setOnItemSelectedListener(new OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> arg0, View arg1,int pos, long arg3) {
// TODO Auto-generated method stub
sstate = state.getSelectedItem().toString();
/* String sub= state.getItemAtPosition(0).toString();
if(sub=="sub1")
suburb.setText("sub1") ; */
suburb.setText(arg0.getItemAtPosition(pos).toString());
}
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});

state.setOnItemSelectedListener(new OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> adapterView, View view,int i, long l) {
sstate = state.getSelectedItem().toString();
suburb.setText(sstate);
}
}

Check selected item of ListView

I have a ListView and need to check, which item has been clicked.
The way I have it, it only shows my the selected item when I use the scrollwheel of my mouse (when testing it in the Eclipse emulator). When I test it on a real mobile device, it doesn't react at all.
adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, listItems);
listView.setAdapter(adapter);
listView.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
myFunction(listView.getSelectedItem());
}
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});

Use setOnItemClickListener instead of setOnItemSelectedListener
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
//get value for listItems using position
String str =listItems[position];
myFunction(str);
}
});

I think better you need to use on onListItemClick listener
public void onListItemClick(ListView parent, View v, int position, long id)
{
parent.setItemChecked(position, parent.isItemChecked(position));
Toast.makeText(this, "You have selected" + items[position],30).show();
}

Can't get string from spinner

I have spinner that have 5 text string. I want to get a string from the spinner, but I only get the first string (i can't get the second, third.....).
i use this syntax(below) but still failed:
Spinner spinner = (Spinner) findViewById(R.id.spinnerItem);
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(
this, R.array.SpinnerArray, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);
String SpinnerText = myspinner.getSelectedItem().toString();

By using onItemSelectedLIstener() method you can get each spinner value into string.
Main.java
spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
// TODO Auto-generated method stub
String selection=spinner.getSelectedItem().toString();
Toast.makeText(getApplicationContext(), "Selected" + selection, 30).show();
}

To get the selected item from the spinner first you need to set the listener for spinner using
spinner.setOnItemSelectedListener(this);
and u need to implement the interface OnItemSelectedListener
and finally override the methods
public void onItemSelected(AdapterView<?> parent, View v, int position, long id) {
selection.setText(items[position]);
}
public void onNothingSelected(AdapterView<?> parent) {
selection.setText("");
}

try this code
in onclick listener of spinner use this code to get String of selected item
String s = spinneradapter.getItemAtPosition(Integer.parseInt(position));
hope this help

Use this :
String mySpinner = spinner.getItemAtPosition(spinner.getSelectedItemPosition()).toString();

spinner.getItemAtPosition(0).toString()//First string
spinner.getItemAtPosition(1).toString()//second string
spinner.getItemAtPosition(2).toString()//third string

see below code it may help you.
spin_search.setOnItemSelectedListener(new OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> arg0, View arg1, int id,
long arg3) {
Toast.makeText(Sms_logs.this, "you select : " + adapter.getItem(id), 2000).show();
}
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});

Spinner on value Change

I have two spinner in my system. Now I have to change the selected value of the 2nd spinner depending on the first spinner value. As soon as the user will change the 1st spinner value, the 2nd spinner value will set automatically depending upon the 1st spinner's selected value. How to implement this?

From the Hello Spinner tutorial:
Now create a nested class that implements AdapterView.OnItemSelectedListener. This will provide a callback method that will notify your application when an item has been selected from the Spinner. Here's what this class should look like:
public class MyOnItemSelectedListener implements OnItemSelectedListener {
public void onItemSelected(AdapterView<?> parent,
View view, int pos, long id) {
Toast.makeText(parent.getContext(), "The planet is " +
parent.getItemAtPosition(pos).toString(), Toast.LENGTH_LONG).show();
}
public void onNothingSelected(AdapterView parent) {
// Do nothing.
}
}
The AdapterView.OnItemSelectedListener requires the onItemSelected() and onNothingSelected() callback methods. The former is called when an item from the AdapterView is selected, in which case, a short Toast message displays the selected text; and the latter is called when a selection disappears from the AdapterView, which doesn't happen in this case, so it's ignored.
Now the MyOnItemSelectedListener needs to be applied to the Spinner. Go back to the onCreate() method and add the following line to the end:
spinner.setOnItemSelectedListener(new MyOnItemSelectedListener());
In other words, you need to create an OnItemSelectedListener that modifies the value of the second spinner, and attach it to the first spinner.

You have to put the condition on onItemSelected of very first spinner. By this example you can get value of 2nd spinner depending on 1st spinner:
public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2,long arg3) {
if(arg0.equals(spin0)){
spin1.setClickable(true);
if(spin0.getSelectedItem().equals("India"))
{
ArrayAdapter <String> s1 = new ArrayAdapter <String> (this,android.R.layout.simple_spinner_item,states_india);
s1.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spin1.setAdapter(s1);
}
else if(spin0.getSelectedItem().equals("Pakistan"))
{
ArrayAdapter <String> s2 = new ArrayAdapter <String> (this,android.R.layout.simple_spinner_item,states_pak);
s2.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spin1.setAdapter(s2);
}
else if(spin0.getSelectedItem().equals("China"))
{
ArrayAdapter <String> s3 = new ArrayAdapter <String> (this,android.R.layout.simple_spinner_item,states_china);
s3.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spin1.setAdapter(s3);
}
}
}

You should define the onItemSelected() separately for each spinner. Otherwise the code gets executed if anything is selected from either spinners.
newCategory.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
// TODO Auto-generated method stub
String selCat = newCategory.getItemAtPosition(arg2).toString();
if (selCat != "New")
{
loadSpinnerData(topic);
}
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
newTopic.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
loadSpinnerData()
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
