Spinner supprimer des éléments

J'ai développé une application dans laquelle j'ai une valeur de modification de texte de l'édition de texte est entré en cône sur le bouton cliqué sur l'article que j'sélectionnez supprimer est supprimé mais le problème est que lorsque je supprime le dernier élément de spinner ensemble spinner liste des bouffées de chaleur . je veux supprimer uniquement l'élément sélectionné(seul le dernier élément)

Mon code est comme suit :

@Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main);
///////////////////////////////////////////////////////////////
//grab our UI elements so we can manipulate them (in the case of the
//Spinner)
//or add listeners to them (in the case of the buttons)
m_myDynamicSpinner = (Spinner) findViewById(R.id.dynamicSpinner);
m_addItemText = (EditText) findViewById(R.id.newSpinnerItemText);
Button addButton = (Button) findViewById(R.id.AddBtn);
Button clearButton = (Button) findViewById(R.id.ClearBtn);
////////////////////////////////////////////////////////////////
//create an arrayAdapter an assign it to the spinner
m_adapterForSpinner = new ArrayAdapter(this,
android.R.layout.simple_spinner_item);
((ArrayAdapter) m_adapterForSpinner)
.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
m_myDynamicSpinner.setAdapter(m_adapterForSpinner);
//m_adapterForSpinner.add("dummy item");
////////////////////////////////////////////////////////////////
//add listener for addButton
addButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
addNewSpinnerItem();
}
});
clearButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
clearSpinnerItems();
}
});
}
////////////////////////////////////////////////////////////////
//add listener for addButton
private void addNewSpinnerItem() {
Log.v("TAG", "addNewSpinnerItems called");
if (m_addItemText.getText().length() == 0) {//||(m_addItemText.getText().toString()==
//" ")){
Log.v("In if cndtn", "textHolder is of length 0");
Toast.makeText(getApplicationContext(), "The textView is empty",
Toast.LENGTH_LONG).show();
//m_myDynamicSpinner.clearFocus();
//m_myDynamicSpinner.setFocusable(false);
//m_addItemText.setFocusable(true);
} else {
CharSequence textHolder = "" + m_addItemText.getText();
//else{
Log.v("else", textHolder + "");
//m_adapterForSpinner.add(textHolder);
//}
((ArrayAdapter) m_adapterForSpinner).add(textHolder);
}
m_addItemText.setText("");
}
private void clearSpinnerItems() {
//m_adapterForSpinner.clear();
Log.v("TAG", "clearSpinnerItems called");
m_myDynamicSpinner
.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent,
View view, int pos, long id) {
//TODO Auto-generated method stub
Log.v("TAG", "Itemseleted to be removed is "
+ m_adapterForSpinner.getItem(pos).toString());
Log.v("Position of item", pos + "");
Object t = m_adapterForSpinner.getItem(pos);
Log.v("Object t ", (String) t);
((ArrayAdapter) m_adapterForSpinner).remove((CharSequence) t);
Log.v("Item removed", t + "");
//m_myDynamicSpinner.setSelected(false);
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
//TODO Auto-generated method stub
}
});
//m_adapterForSpinner.add("dummy item");
}
