Android App - 按相同spinner item 可觸發 event

admin

spinner.setOnClickListener(new
View.OnClickListener()
{
public
void onClick(View v)
{
// Do some stuff before the user changes the selection
...

spinner.setOnItemSelectedListener(new
OnItemSelectedListener()
{
@Override
public
void onItemSelected(AdapterView<?> parent,
View view,
int pos,
long id)
{
// Do some stuff based onItemSelected

You will have to set the Click listener on the underlying view (normally a TextView with id: android.R.id.text1) of the spinner. To do so:

• Create a custom Spinner
• In the constructor (with attributes) create the spinner by supplying the layout android.R.layout.simple_spinner_item
• Do a findViewById(android.R.id.text1) to get the TextView
• Now set the onClickListener to the TextView
