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
}
});

When I click a spinner item,I would like list view to shows more details on that item.
i.e if I select Student from Spinner then list view should show student names.
spin.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
Toast.makeText(SpinnerActivity.this, parent.getItemAtPosition(position)+" ", Toast.LENGTH_LONG).show();
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
What is the right way to do it ?
Create an ArrayList with Strings(Student names). Now create an ArrayAdapter in onCreate() which contains the Students ArrayList.
In the EventListener(onItemSelected) of the Spinner, check for the Spinner-item text. If it's "Students" set the ArrayAdapter of the Spinner to the Students-ArrayAdapter which you initialized in onCreate();
onCreate():
arrayList = new ArrayList<String>();
arrayList.add("Bob");
adapter = new ArrayAdapter<String>(getApplicationContext(), android.R.layout.simple_spinner_item, arrayList);
onItemSelected EventListener:
if(view.getText().toString().equals("Students"){
listView.setAdapter(adapter);
}
I'm looking for something similar to a drop down menu but when you click on it a block of text drops instead of a list of clickable items. Then you should be able to click to close it again when finished. My app is an informational app so, I want to make a list of several of these within a glossary in my app.
Any ideas??
you should use Spinner in android:
Here is the example :
Spinner mSipnner = (Spinner)findViewById(R.id.spin_beneficiary_targetcode);
List<String> categories2 = new ArrayList<String>();
categories2.add("Choose code");
categories2.add("001");
categories2.add("002");
categories2.add("003");
categories2.add("004");
categories2.add("005");
ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, categories2);
dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
mSpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
////Spinner item selected
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
// On selecting a spinner item
String targetCode_item = parent.getItemAtPosition(position).toString();
// Showing selected spinner item
//Toast.makeText(parent.getContext(), "Selected: " + category_item, Toast.LENGTH_LONG).show();
}
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
// attaching data adapter to spinner
mSpinner.setAdapter(dataAdapter);
i have some data coming from server and i have to show that value in Android Spinner.
Adapter that is attach to Spinner also getiing from server.
please let me know how to show initial value coming from server.and show adapter value after click on Spinner.
Spinner mySpinner = (Spinner) findViewById(R.id.householdspinner);
mySpinner.setAdapter(new ArrayAdapter<String>(Edit_Voter_Information.this,
android.R.layout.simple_spinner_dropdown_item,
householdIncome));
mySpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> arg0,
View arg1, int position, long arg3) {
String item = arg0.getItemAtPosition(position).toString();
house_Hold_Income = item;
#Override
public void onNothingSelected(AdapterView<?> arg0) {
}
});
}
Initially i stored some values in String[] names. when activity is run spinner position 0(zero)is selected by default.
Check my code below:
ArrayAdapter arrayAdapter = new ArrayAdapter(this, R.layout.spinner_style, names);
spinner.setAdapter(arrayAdapter);
spinner.getSelectedItemPosition();//which returns names[0] initially.
if click other position(i) it returns names[i], where i =0,1,2,..
I want to show first item as a default text on spinner but in the drop down list that item is not shown like there is arraylist
final ArrayList<String> spinnerArray = new ArrayList<String>();
spinnerArray.add("number");
spinnerArray.add("one");
spinnerArray.add("two");
spinnerArray.add("three");
The number is always shown as a default text on spinner but after clicking on spinner there is one, two, three is shown in drop down list. when we select any number one, two three the default text number is not changed. How can i do it?
ArrayAdapter<String> adapte = new ArrayAdapter<String>(this,
android.R.layout.simple_spinner_item, spinnerArray);
adapte.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spin.setAdapter(adapte);
spin.setOnItemSelectedListener(new OnItemSelectedListener()
{
public void onItemSelected(AdapterView<?> parent, View arg1,int pos, long arg3)
{
}
public void onNothingSelected(AdapterView<?> arg0) {
}
});
Try this, it show the default as Number..
May be this help you
String[] priceString = { "Number", "one, "two"};
Spinner priceSpinner = (Spinner) findViewById(R.id.price_spinner);
ArrayAdapter priceAdapter = new ArrayAdapter( this.getActivity(), android.R.layout.simple_spinner_item,priceString); priceSpinner.setAdapter(priceAdapter);
I recently posted a question on how to change the values of a spinner during program execution and was told to change the array used to make the adaptor and call notifyDataSetChanged();
I tried that but my spinner is not getting updated even though my array is. I attach the code below
public void onCreate(Bundle savedInstanceState)
{
res=getResources();
Boolean a;
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// First spinner whose value determines the value of the second spinner
spinner = (Spinner) findViewById(R.id.spinner1);
// ArrayAdaptor of first spinner
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource( this R.array.planets_array, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);
spinner2 = (Spinner) findViewById(R.id.spinner2);
spinner2.setVisibility(4);// spinner 2 is not visible initially
// ArrayAdaptor of first spinner
adapter2 = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, spinner_drop);
adapter2.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner2.setAdapter(adapter2);
Context context = getApplicationContext();
spinner.setOnItemSelectedListener(new MyOnItemSelectedListener());
}
public class MyOnItemSelectedListener implements OnItemSelectedListener
{
public void onItemSelected(AdapterView<?> parent, View view, int pos, long id)
{
if(pos!=0)
{
//copying string array of second spinner from strings.xml to the current string array
spinner_drop=res.getStringArray(R.array.activities_array2);
Toast.makeText(parent.getContext(), "The planet is " +spinner_drop[0] , Toast.LENGTH_SHORT).show(); //this toast shows up
adapter2.notifyDataSetChanged();
spinner2.refreshDrawableState();
spinner2.setVisibility(0);//this command works and the spinner is visible, but it is empty
}
}
public void onNothingSelected(AdapterView parent)
{
// Do nothing.
}
}
Any idea what I am doing wrong any ideas will help.
PS: I have tried removing the entire invisible, visible thing, doesnt help
Thanks in advance
Modify your onItemSelected method as follows, note the new addition I added below.
public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {
if (pos!=0) {
//copying string array of second spinner from strings.xml to the current
//string array
spinner_drop=res.getStringArray(R.array.activities_array2);
Toast.makeText(parent.getContext(), "The planet is " +spinner_drop[0],
Toast.LENGTH_SHORT).show(); //this toast shows up
adapter2.notifyDataSetChanged();
spinner2.setAdapter(adapter2); // <--- New Addition
// spinner2.refreshDrawableState();
spinner2.setVisibility(0); //this command works and the spinner is visible,
//but it is empty
}
}
