please give brief answer to my question...
setOnItemSelectedListener(this) for both?spinner.getSelectedItemPosition(); on both the spinners?waiting for ur valuable replies. reference materials are also appreciable
Yes, you can have multiple spinner's that can be managed by single listener or you can have seperate Listener for each.
For Single Listener you can do something like this,
Set the Listener
spinner1.setOnItemSelectedListener(this); spinner2.setOnItemSelectedListener(this); Then you can use onItemSelected to get perform the action related to the spinner's.
@Override public void onItemSelected(AdapterView<?> parent, View view, int position,long arg3) { int id = parent.getId(); switch (id) { case R.id.spinner1: // your stuff here break; case R.id.spinner2: // your stuff here break; } Check this:
Spinner spinner0, spinner1, spinner2; TextView textView0, textView1, textView2;
@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); textView0 = (TextView) findViewById(R.id.text0); spinner0 = (Spinner) findViewById(R.id.spinner0); ArrayAdapter<String> adapter0 = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_spinner_item, text0); adapter0.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); spinner0.setAdapter(adapter0); spinner0.setOnItemSelectedListener(onItemSelectedListener0); textView1 = (TextView) findViewById(R.id.text1); spinner1 = (Spinner) findViewById(R.id.spinner1); ArrayAdapter<String> adapter1 = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_spinner_item, text1); adapter1.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); spinner1.setAdapter(adapter1); spinner1.setSelection(0,false); //make sure only one listener is //active in the onCreate method by setting the other listener as false spinner1.setOnItemSelectedListener(onItemSelectedListener1);
textView2 = (TextView) findViewById(R.id.text2); spinner2 = (Spinner) findViewById(R.id.spinner2); MySpinnerAdapter adapter2 = new MySpinnerAdapter(MainActivity.this, android.R.layout.simple_spinner_item, obj2); //adapter2.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); spinner2.setAdapter(adapter2); spinner2.setSelection(0,false); spinner2.setOnItemSelectedListener(onItemSelectedListener2); } OnItemSelectedListener onItemSelectedListener0 = new OnItemSelectedListener() { @Override public void onItemSelected(AdapterView<?> parent, View view, int position, long id) { //do your stuff spinner0 } @Override public void onNothingSelected(AdapterView<?> parent) { } }; OnItemSelectedListener onItemSelectedListener1 = new OnItemSelectedListener() { @Override public void onItemSelected(AdapterView<?> parent, View view, int position, long id) { //do your stuff spinner1 } @Override public void onNothingSelected(AdapterView<?> parent) { } }; OnItemSelectedListener onItemSelectedListener2 = new OnItemSelectedListener() { @Override public void onItemSelected(AdapterView<?> parent, View view, int position, long id) { //do your stuff spinner2 } @Override public void onNothingSelected(AdapterView<?> parent) { } }; }
If the reference of two spinners are different(which will be , if you are using 2 spinners) , give different IDs for them and you can uniquely identify them, Yes you can set click listener to both of them individually.
spinner.setOnItemSelectedListener(new OnItemSelectedListener() { ... } ); spinner1.setOnItemSelectedListener(new OnItemSelectedListener() { ... } ); 
spinner1.getSelectedItemPosition(), spinner2.getSelectedItemPosition()
