I have developed an application in which i have one edit text value of edit text is entered in spinner on button clicked an the item i select to delete gets deleted but the problem is that when i delete the last item of spinner whole spinner list flushes . i want to delete only selected item(only last item)
My code is as follows :
@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");
}
for delete all items use:
mySpinner.setAdapter(null);
if you want to delete a particular item, remove this from m_adapterForSpinner and then:
mySpinner.setAdapter(m_adapterForSpinner);
