I want to get information using putExtra() on another page and I can do it, but my only problem is always the default value the first value sample_array but i want to by default classDayIntent value is displayed in spinner
tip: The putExtra() received in Spinner is there
First Activity:
Intent intent = new Intent();
intent.putExtra("className" , className);
intent.putExtra("uniName" , uniName);
intent.putExtra("classDay" , classDay);
intent.setClass(context , AddNewClass.class);
context.startActivity(intent);
Second Activity:
Spinner spinner = (Spinner)findViewById(R.id.spinnerDay);
String className = getIntent().getStringExtra("className");
String uniName = getIntent().getStringExtra("uniName");
String classDayInent = getIntent().getStringExtra("classDay"); // How To Display classDayInent In Spinner....
className_EditeText.setText(className);
uniName_EditeText.setText(uniName);
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this , R.array.sample_array , android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
String classDay = parent.getSelectedItem().toString();
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
Strings:
<resources>
<string name="app_name">ClassManager</string>
<string-array name="sample_array">
<item>شنبه</item>
<item>یکشنبه</item>
<item>دوشنبه</item>
<item>سه شنبه</item>
<item>چهارشنبه</item>
<item>پنجشنبه</item>
<item>جمعه</item>
</string-array>
you can use add function of adapter.
since CharSequence is an interface, and the String class implements CharSequence so you can directly add string to adapter
adapter.add(classDayInent);
spinner.setAdapter(adapter);
Another issue is , createFromResources creates a immutable list mean it cannot add more items.
Solution : create your own adapter with mutable list
List<String> list = new ArrayList<>(Arrays.asList(getResources().getStringArray(R.array.sample_array)));
ArrayAdapter<String> adapter = new ArrayAdapter<>(this , android.R.layout.simple_spinner_item,list);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
list.add(0,classDayIntent);// to add received element at first position to display
spinner.setAdapter(adapter);
You can get your xml arraylist and then add to that:
List<String> ar = new LinkedList<String>(Arrays.asList(getResources().getStringArray(R.array.sample_array)));
ar.add("test");
i found correct answer :
String classDayInent = getIntent().getStringExtra("classDay");
List<String> list = new ArrayList<String>(Arrays.asList(getResources().getStringArray(R.array.sample_array)));
ArrayAdapter<String> adapter = new ArrayAdapter<>(this , android.R.layout.simple_spinner_item,list);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);
//find classDayIntent from List For get Position To Display
for (int i = 0; i < list.size(); i++)
{
if (classDayIntent.equals(list.get(i)))
{
spinner.setSelection(i);
}
}
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id)
{
classDay = parent.getSelectedItem().toString();
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});

I'm developing a e-com app. I'm trying to create dynamic spinner. Spinner is dependent upon product attributes. I'm able to create spinners also mapped data on them but I want to get all spinners selected item whenever a spinner change its data so I can match to correct variant of product.
Here is my code snippet
final List<Attribute> attributes = product_.getAttributes();
for (i = 0; i < attributes.size(); i++) {
ArrayList<String> spinnerArray = (ArrayList<String>) attributes.get(i).getOptions();
ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>(getActivity(), android.R.layout.simple_spinner_dropdown_item, spinnerArray);
Spinner spinner = new Spinner(getActivity());
spinner.setAdapter(spinnerArrayAdapter);
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> adapterView, View view, int position, long l) {
}
#Override
public void onNothingSelected(AdapterView<?> adapterView) {
}
});
dynamicProductProperties.addView(spinner);
}
First, you need to set same instance of OnItemSelectListener to your all spinners. Let your activity or fragment implement OnItemSelectListener then call spinner.setOnItemSelectListener(this);
In onItemSelected method you can run this code to have selecteds.
ArrayList<String> selectedList = new ArrayList();
for (int i = 0; i < dynamicProductProperties.getChildCount(); i++) {
View view = dynamicProductProperties.getChildAt(i);
if (view instanceof Spinner){
String selected = (String) ((Spinner) view).getSelectedItem();
selectedList.add(TextUtils.isEmpty(selected) ? "" : selected);
}
}
Good luck

I have 2 spinners in an activity.
Based on the selection of one item in spinner1, relevant data should be loaded in spinner2. Consider spinner1 has data related to country and spinner2 has data related to state.
I should be able to get this done once the activity is created and if the user changes the selection in spinner1.
But I am stuck with populating the spinner2 data based on the saved value of spinner1.
I am calling spinner1.setSelection(indexSaved) but since I am only loading spinner2 in the onItemSelectedOf of spinner1, setSelection of spinner1 is not firing the onItemSelected.
Please let me know how I can achieve this.
I have done same thing in my project without any problem:
Below is code may be it help you:
On Create Method filled state list:
//initialize spinners
spinnerStateList = (Spinner) findViewById(R.id.spinnerStateList);
spinnerDistrictsList = (Spinner) findViewById(R.id.spinnerDistrictsList);
fillStateList();
public void fillStateList()
{
states = manage_states.fetchAllStates(getApplicationContext());
//add new element for select name
states.add(0,new RowItem("-1", "Select State"));
String[] spinnerArray = new String[states.size()];
for(int i= 0;i<states.size();i++)
{
spinnerArray[i] = states.get(i).getName();
}
ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item,spinnerArray);
dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinnerStateList.setAdapter(dataAdapter);
spinnerStateList.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> arg0,
View arg1, int position, long arg3) {
String selectedStateID = states.get(position).getId();
fillDistrictsSelectionChangeState(selectedStateID);
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
}
});
}
public void fillDistrictsSelectionChangeState(String selectedStateID)
{
if(selectedStateID.equalsIgnoreCase("-1"))
{
linearLayoutDistrictsList.setVisibility(LinearLayout.GONE);
linearLayoutBlocksList.setVisibility(LinearLayout.GONE);
linearLayoutPHCList.setVisibility(LinearLayout.GONE);
linearLayoutSHCList.setVisibility(LinearLayout.GONE);
}
else
{
linearLayoutDistrictsList.setVisibility(LinearLayout.VISIBLE);
districts = manage_districts.fetchAllDistrictsByStateId(getApplicationContext(), selectedStateID);
//add new element for select name
districts.add(0,new RowItem("-1", "Select District"));
String[] spinnerArray = new String[districts.size()];
for(int i= 0;i<districts.size();i++)
{
spinnerArray[i] = districts.get(i).getName();
}
ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item,spinnerArray);
dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinnerDistrictsList.setAdapter(dataAdapter);
spinnerDistrictsList.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> arg0,
View arg1, int position, long arg3) {
String selectedDistrictID = districts.get(position).getId();
fillBlocksSelectionChangeDistrict(selectedDistrictID);
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
}
});
}
}
Hi I am creating a list of spinners dynamically based on a user choice. Here I am also implementing OnItemSelectedListener for each of the spinners, since there are multiple spinners I want to know which spinner's method is currently being accessed. Here's the code,
for (int i = 0; i < count; i++) {
ArrayList<String> spinnerArray = new ArrayList<String>();
spinnerArray.add("one");
spinnerArray.add("two");
spinnerArray.add("three");
spinnerArray.add("four");
spinnerArray.add("five");
Spinner spinner = new Spinner(this);
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> parent, View view,
int position, long id) {
Object item = parent.getItemAtPosition(position);
Log.d("vij-debug", "selector1 no is " + item);
Log.d("vij-debug", "selector1 id is"+ view.getId());
//medicineArray1[i][1]=(String)item;
// here I want to access the iteration value i
}
public void onNothingSelected(AdapterView<?> parent) {
}
});
ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>(
this, android.R.layout.simple_spinner_dropdown_item,
spinnerArray);
spinner.setAdapter(spinnerArrayAdapter);
Can anyone suggest a suitable solution?
Set the Spinner's tag to i upon creation, then retrieve it from the AdapterView<?> parent parameter in onItemSelected().
Spinner spinner = new Spinner(this);
spinner.setTag(i);
...
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener()
{
public void onItemSelected(AdapterView<?> parent, View view, int position, long id)
{
int spinnerNumber = parent.getTag();
}
...
}
);
you could use a List and store your spinner there. in your for loop
//inside for loop
List<Spinner> spinnerList=new ArrayList<Spinner>();
Spinner spinner = new Spinner(this);
spinnerlist.add(spinner);
//end
//outside for loop
for(int i=0;i<spinnerList.size();i++){
setListenerToSpinner(spinnerList.get(i));
}
//end
//function
public void setListenerToSpinner(Spinner spinner){
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> parent, View view,
int position, long id) {
Object item = parent.getItemAtPosition(position);
Log.d("vij-debug", "selector1 no is " + item);
Log.d("vij-debug", "selector1 id is"+ view.getId());
//medicineArray1[i][1]=(String)item;
// here I want to access the iteration value i
}
}
I want to show the value of spinner in string instead of integer. Right now it is showing integer like '0','1'.
Setting activity:
public class Setting extends Activity {
bloodtype = (Spinner) findViewById(R.id.spinner2);
ArrayAdapter<String> adapter2 = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item,getResources().getStringArray(R.array.blood_groups_arrays));
adapter2.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
bloodtype.setAdapter(adapter2);
bloodtype.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
/**
* Called when a new item is selected (in the Spinner)
*/
public void onItemSelected(AdapterView<?> parent,
View view, int position, long id) {
sharedpreferences.edit().putString(BloodType, parent.getItemAtPosition(position).toString()).commit();
}
public void onNothingSelected(AdapterView<?> parent) {
// Do nothing.
}
});
if(sharedpreferences.contains(BloodType)) {
bloodtype.setSelection(sharedpreferences.getString(BloodType, "DEFAULT"));
}
}
Calling its value in main activity:
if(sharedpreferences.contains(Setting.BloodType)) {
show.setText(""+sharedpreferences.getString(Setting.BloodType, "DEFAULT"));
}
In order to store a value of array you populated your spinner with in SharedPreferences use the following line in onItemSelected() method:
sharedpreferences.edit().putString(BloodType, parent.getItemAtPosition(position).toString()).commit();
Note: BloodType has to be of String type, because it plays a role of a key in key-value pair of SharedPreferences.
Taken from my working project it should work:
adapterSpinner = new ArrayAdapter<String>(yourContenxt,
android.R.layout.simple_list_item_1, yourDataSource);
spinnerProfileType.setAdapter(adapterSpinner);
As you are using a string array you can set the spinner items in xml too by using:
android:entries = "#array/your_string_entry"
I have a spinner which displays both options, but when I accept the female option, it still takes the answer as a male, any suggestions?
List<String> SpinnerArray = new ArrayList<String>();
SpinnerArray.add("Male");
SpinnerArray.add("Female");
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, SpinnerArray);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
Spinner Items = (Spinner) findViewById(R.id.genderSpinner);
Items.setAdapter(adapter);
// Importing all assets like buttons, text fields
inputFullName = (EditText) findViewById(R.id.registerName);
String selected = Items.getSelectedItem().toString();
if (selected.equals("Male")) {
inputGen = "Male";
}
if (selected.equals("Female")){
inputGen = "Female";
}
Following the official guide:
public class SpinnerActivity extends Activity implements OnItemSelectedListener {
...
public void onItemSelected(AdapterView<?> parent, View view,
int pos, long id) {
// An item was selected. You can retrieve the selected item using
// parent.getItemAtPosition(pos)
}
public void onNothingSelected(AdapterView<?> parent) {
// Another interface callback
}
You can try a switch of position and then try your same conditions.
