How to get From Spinner a public String? Thank you ALL

mMap.put("your Key",mySpinner.getSelectedItem().toString());
//the value add to map of volley
}
#Override

Why isn't my onitemlongclick listener working?

From MainActivity:
public class MainActivity extends ListActivity implements AdapterView.OnItemLongClickListener {
private DataSourceSql mDataSourceSql;
protected ArrayList<String> mProfileNames;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mDataSourceSql = new DataSourceSql(MainActivity.this);
mNames = new ArrayList<String>();
//this part here
ListView lv = (ListView) findViewById(android.R.id.list);
lv.setLongClickable(true);
}
The id of the ListView in this case is set in the XML as android:id="#android:id/list".
And then later on in the same activity:
#Override
protected void onListItemClick(ListView l, View v, int position, long id) {
super.onListItemClick(l, v, position, id);
Toast.makeText(this, mNames.get(position), Toast.LENGTH_SHORT).show();
}
#Override
public boolean onItemLongClick(AdapterView<?> l, View v, final int position, long id) {
Toast.makeText(this, "long clicked: " + mNames.get(position), Toast.LENGTH_LONG).show();
return true;
}
But when I long-press an item in the list, the only thing that triggers is onListItemClick. I never get the message with the long click.

You shouldn't implement an interface like AdapterView.OnItemLongClickListener directly in your onCreate().. Just use your old way (Your class implement this interface) and with each method override, you have to write like this:
lv.setOnItemLongClickListener(this);
lv.setonListItemLongClickListener(this);

I think I figured it out, but someone please correct me if I'm missing something.
I removed the "implements..." thing and then added the following to the onCreate method:
lv.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener
() {
#Override
public boolean onItemLongClick(AdapterView<?> av, View v, int
pos, long id) {
onListItemLongClick(v, pos, id);
return false;
}
});
Although I am not sure if I should be returning true or false there.
I also changed the long click function down below to
public boolean onListItemLongClick(View v, final int position, long id) {
Toast.makeText(this, "long clicked: " + mNames.get(position), Toast.LENGTH_LONG).show();
return true;
}
Edit:
Quicker approach is to just add lv.setOnItemLongClickListener(this); to my onCreate method in the OP.

Use This. Your Problem will Solve.
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Toast.makeText(MainActivity.this, "Click", Toast.LENGTH_SHORT).show();
}
});
listView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
#Override
public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
Toast.makeText(MainActivity.this, "Long Click", Toast.LENGTH_SHORT).show();
return true;
}
});

Spinner return null value

when i am selected spinner value then some time it return a true value and some time it return null value
My spinner code is
list.add("Please Select Approver Name");
list.add("bishnu");
list.add("bishnu");
list.add("bishnu");
list.add("bishnu");
ArrayAdapter<String> adp1=new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1,list);
adp1.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
sp1.setAdapter(adp1);
sp1.setSelection(0);
Item Selected Listener
sp1.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {
strspin = parent.getItemAtPosition(pos).toString();
}
public void onNothingSelected(AdapterView<?> parent) {
}
});
Toast.makeText(context, "value"+strspin, Toast.LENGTH_LONG).show();
I am working on it past two day
Please Help Me how i can fix this problem

Use the Toast inside the onITemSelected method as below.
sp1.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {
strspin = parent.getItemAtPosition(pos).toString();
Toast.makeText(context, "value"+strspin, Toast.LENGTH_LONG).show();
}
public void onNothingSelected(AdapterView<?> parent) {
}
});

Unable to get Spinner value when click item

I am here trying display seleted value from dropdown spinner, but mysetOnItemSelectedListener is not working
My code is as follows:-
ArrayAdapter<String> adapter =new ArrayAdapter<String>(this, R.array.location,list);
spinner.setAdapter(adapter);
spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> parent, View view,
int pos, long id) {
Toast.makeText(
parent.getContext(),
"The color is "
+ parent.getItemAtPosition(pos).toString(),
Toast.LENGTH_LONG).show();
}
public void onNothingSelected(AdapterView<?> parent) {
}
});

ArrayAdapter<CharSequence> adapter=ArrayAdapter.createFromResource(this,R.array.location,android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);
spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> parent, View view,
int pos, long id) {
Toast.makeText(
parent.getContext(),
"The color is "
+ spinner.getSelectedItem().toString(),
Toast.LENGTH_LONG).show();
}
public void onNothingSelected(AdapterView<?> parent) {
}
});
Make necessary changes and try the above code.If it not works then change Charsequence to String.

try this code
spin.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
Employee employee = employees.get(position);
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
