Android fill spinner dynamically - android

if I have two spinner and add to first spinner as:
int pos=0;
spinner1 = (Spinner) findViewById(R.id.spinner1);
List<String> list = new ArrayList<String>();
list.add("list 1");
list.add("list 2");
list.add("list 3");
ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(this,
android.R.layout.simple_spinner_item, list);
dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner1.setAdapter(dataAdapter);
spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) {
pos=position;
}
#Override
public void onNothingSelected(AdapterView<?> parentView) {
}
});
And now I want to fill the second spinner Based on the position of first spinner How do I do that?
e.g.
if pos->0 second spinner Contains {A,B,C}
if pos->1 second spinner Contains {D,E,F}
... etc.
thanks in advance...

In onItemSelected(...), change the adapter of the second spinner based on the position of the first. You should be able to reuse some of your code to accomplish this.

String[] spinnerArray = {"Android","ios","other"};
Spinner spinner = new Spinner(this);

if(position==1)
{
TextView tv = new TextView(MainActivity.this);
tv.setText("Hello");
rl.addView(tv);
}
}
#Override

Do you know how LinearLayout works?
http://developer.android.com/reference/android/widget/LinearLayout.html
You should call
addView(tv, 1);
Specifying position on where to insert view.

how to shorten spinner selected item text in android?

I have used android custom spinner.
My custom spinner look like bellow
My List data is like
List<String> list = new ArrayList<String>();
list.add("001-00434016457-Md. Mokhhlesur Rahman");
list.add("001-00434016724-Mohammad Nazim Ullah");
list.add("001-00434016725-Mohsin Kabir");
list.add("001-00434016881-Maruf Pervaz Khan");
list.add("001-00434017171-Md.Nazmul Hasan");
My Spinner Adapter and setting data in spinner is like bellow
Spinner spinner = (Spinner) findViewById(R.id.spinner);
ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(this,
android.R.layout.simple_spinner_item, list);
dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(dataAdapter);
My problem is spinner's item text is large like "001-00434016881-Maruf Pervaz"
I want to select only id like 001-00434016881.
I don't want to get full text of the spinner item selection. How can I remove name part like -Maruf Pervaz Khan from 001-00434016881-Maruf Pervaz on item selection from spinner.
Please Help me
Try this. If the row item maintains same pattern as 001-00434016881-Md.Some Name
spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
Toast.makeText(MainActivity.this, adapter.getItem(position).substring(0,adapter.getItem(position).lastIndexOf("-")), Toast.LENGTH_LONG).show();
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
// TODO Auto-generated method stub
}
});

Item selection in spinner doesn't detect in MyOnItemSelectedListener

I have activity with 3 spinners and selection of 1st spinner is related to 2nd and 2nd selection is related to the 3rd, so I have the spinner code one inside one.
CrustSp, SizeSp and extraDescriptionOneSP are the 3 spinners I have. I have loaded the items to the Spinners and I can select a value as well. But my problem is whenever i made a selection in CrustSp and SizeSp doesn't show in MyOnItemSelectedListener(). But if I made a selection in extraDescriptionOneSP it shows inside MyOnItemSelectedListener().
I can't figure where I have gone wrong, anyone can point out where I have gone wrong it will be really helpful.
This the code
crust = Utils.removeDuplicatesFromList(crust);
ArrayAdapter<String> dataAdapterCru = new ArrayAdapter<String>(
this, android.R.layout.simple_spinner_item, crust);
dataAdapterCru
.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
crustSP.setAdapter(dataAdapterCru);
crustSP.setOnItemSelectedListener(new MyOnItemSelectedListener(
ActivityPizzaCustomize.this) {
public void onNothingSelected(AdapterView<?> arg0) {
}
#Override
public void onItemSelected(AdapterView<?> parent,
View view, int position, long id) {
String crustSelectedItem = crustSP.getSelectedItem()
.toString();
List<String> resultSizes = getFilteredSizes(crustSelectedItem);
ArrayAdapter<String> dataAdapterDes = new ArrayAdapter<String>(
ActivityPizzaCustomize.this,
android.R.layout.simple_spinner_item,
resultSizes);
dataAdapterDes
.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
sizeSP.setAdapter(dataAdapterDes);
sizeSP.setOnItemSelectedListener(new MyOnItemSelectedListener(
ActivityPizzaCustomize.this) {
public void onNothingSelected(AdapterView<?> arg0) {
}
#Override
public void onItemSelected(AdapterView<?> parent,
View view, int position, long id) {
String sizeSelectedItem = sizeSP
.getSelectedItem().toString();
List<String> resultTopping = getFilteredToppings(sizeSelectedItem);
extraDescriptionOneSP
.setOnItemSelectedListener(new MyOnItemSelectedListener(
ActivityPizzaCustomize.this));
ArrayAdapter<String> dataAdapterExtraDesOne = new ArrayAdapter<String>(
ActivityPizzaCustomize.this,
android.R.layout.simple_spinner_item,
resultTopping);
dataAdapterExtraDesOne
.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
extraDescriptionOneSP
.setAdapter(dataAdapterExtraDesOne);
extraDescriptionOneSP
.setAdapter(new NothingSelectedSpinnerAdapter(
dataAdapterExtraDesOne,
R.layout.contact_spinner_row_nothing_selected,
ActivityPizzaCustomize.this));
}
});
}
});
MyOnItemSelectedListener method,
public class MyOnItemSelectedListener implements OnItemSelectedListener {
Activity activity;
String StrOneSPPosition;
public MyOnItemSelectedListener(Activity p_activity) {
activity = p_activity;
}
#Override
public void onItemSelected(AdapterView<?> parent, View view,
int position, long id) {
// check which spinner triggered the listener
switch (parent.getId()) {
case R.id.sp_crust: {
String StrCrustSPPosition = String.valueOf(crustSP
.getSelectedItemPosition());
System.out.println("crust = " + StrCrustSPPosition);
System.out.println("crust = " + position);
CrustSPPosition = Integer.parseInt(StrCrustSPPosition);
}
I don't see you using the selected position to determine the data for next spinner. BTW you should not make new adapter for each selection, instead reuse the once made adapter.
