'Spinner does not show selected value
I have implemented the spinner by populating the array list through database.I can get and show the array list in my spinner array adapter but if I select the item in spinner it does not shown in spinner?What I had mistake here?
Here is my code,
Spinner spinner1 = (Spinner) findViewById(R.id.prospin);
ArrayAdapter<String> adapter1 = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item, providerlist);
adapter1.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner1.setAdapter(adapter1);
I get the selected item string by using this,
Spinner provid = (Spinner)findViewById(R.id.prospin);
String provider =provid.getSelectedItem().toString();
Can anyone help me out pls!!!

This answer may be a little stupid but try it. It worked for me.
- Check the background color of your spinner!
- And if it`s white change it
- Enjoy it!

I got same problem and solved by adding notifyDataSetChanged() after binding data in Spinner.
First of all I have bind adapter with Blank ArrayList then getting List of Items from Server and added to that List but forgot to notifyDataSetChanged() after updated List.
just add adapter.notifyDataSetChanged(); after updating list.
Hope it will helpful.

Problem:
Spinner displays neither the default nor selected item value. But drop-down menu items are show when selected.
Cause:
Background and text color both being white!!!
Solutions:
xml(Preferable):
Write a custom layout for a spiner item and use it instead of the default,android.R.layout.simple_spinner_item.
How to change spinner text size and text color?
Code(Less reliable):
your_spinner_instance.setOnItemSelectedListener(new Spinner.OnItemSelectedListener(){
public void onItemSelected(AdapterView<?> parent, View view, int pos,
long id) {
((TextView) view).setTextColor(Color.RED);
}
public void onNothingSelected(AdapterView<?> parent) {
}
});
Android needs some major update or maybe dart and flutter should take over...
Thanks Catluc

Use wrap_content for the height of Spinner.
Probably it does not have enough height to show text.
Solution 5:[5]
Well this also happens if the context is not properly given. I was using getApplicationContext() where as it needs getBaseContext().
Solution 6:[6]
if you have a custom adapter you should change the TextView text color
@Override
public View getView(int position, View convertView, ViewGroup parent) {
TextView view = (TextView) super.getView(position, convertView, parent);
view.setTextColor(Color.parseColor("#000000"));
return view;
}
and if you don't have a custom adapter you should just change spinner background
Solution 7:[7]
I was using hardcoded value for width and height. After changing to wrap_content it works.
Solution 8:[8]
For me the problem is that I was using getApplicationContext(). When I replace getApplicationContext() with this it works fine.
ArrayAdapter<*> adapter = new ArrayAdapter<>(this, android.R.layout.simple_spinner_item, documentsCategories);
Solution 9:[9]
use android:spinnerMode="dropdown" attribute in your declared Spinner element's xml
Solution 10:[10]
I just had this problem and after trying all of the solutions listed found out that the issue was that I had set the spinner layout_width to 60dp.
Changed it to fill_parent and problem solved.
Solution 11:[11]
This happens occasionally, I guess it's a bug but there's a workaround which is funny but just do it,
In the property bar of the spinner set the background to a different color,
In your .xml where you have your spinner, set:
android:background="@android:drawable/spinner_background_material"
run the code it will generate an error saying the background is private
delete the line of the android:background in the .xml and run the code again,your spinner should work fine showing all the values, if it doesn't take the extra step of setting background tint to a different color preferably black.
Run it again.

I had the same problem, and none of the solutions were working for me. Finally found the problem was that the spinner was being populated from firestore db via an async task. Rearranged the code so that the adapter is set after the async task completion, and voila!!
Solution 13:[13]
add background color white and the details will display
for example
<Spinner
android:id="@+id/size_spinner"
style="@style/FormTextStyle"
android:drawSelectorOnTop="true"
android:layout_marginStart="@dimen/default_gap"
android:background="@android:color/white"
/>

Else, try to store it on selecting the item:
spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> adapter, View v,
int position, long id) {
// On selecting a spinner item
String item = adapter.getItemAtPosition(position).toString();
// Showing selected spinner item
Toast.makeText(getApplicationContext(),
"Selected Country : " + item, Toast.LENGTH_LONG).show();
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
Solution 15:[15]
Try this.
final ArrayList<String> providerlist= new ArrayList<String>();
Spinner spinner1 = (Spinner) findViewById(R.id.prospin);
ArrayAdapter<String> adapter1 = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item, providerlist);
adapter1.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner1.setAdapter(adapter1);
spinner1.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
// On selecting a spinner item
String item = providerlist.get(position);
// Showing selected spinner item
Toast.makeText(this,
"Selected Country : " + item, Toast.LENGTH_LONG).show();
}
@Override
public void onNothingSelected(AdapterView<?> parent) {
}
});

Generally spinners gets selected by default when they are used ,so try to set blank,or any other data to first position that is zero position, you will get exact position of you selected item .
Solution 17:[17]
The issue from what I found was with the style sheet.Use this
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="windowNoTitle">false</item>
<item name="windowActionBar">true</item>
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
</style>
For the xml layout use this
<?xml version="1.0" encoding="utf-8"?>
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:fitsSystemWindows="true"
android:paddingBottom="5dp"
style="@style/AppTheme">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingTop="5dp"
android:paddingLeft="24dp"
android:paddingRight="24dp">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Spinner"
android:layout_marginTop="10dp"
android:textColor="@color/colorBlack"/>
<Spinner
android:id="@+id/Spinner"
android:layout_width="fill_parent"
android:layout_height="50dp"
android:backgroundTint="@color/colorPrimary"
android:textColorHint="#05ab9a"
android:padding="15dp"
style="@style/Base.Widget.AppCompat.Spinner.Underlined"
tools:targetApi="lollipop" />
</LinearLayout>
</ScrollView>
And finally for the class
String [] NUMBERS= {"3 ","6 ","13 "};
Spinner s_spinner = (Spinner) findViewById(R.id.Spinner);
ArrayAdapter<String> spinnerAdapter = new ArrayAdapter<>(this,
android.R.layout.simple_dropdown_item_1line, NUMBERS);
// Specify the layout to use when the list of choices appears
spinnerAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
// attaching data adapter to spinner
s_spinner.setAdapter(spinnerAdapter );

This answer may be a little stupid but if you do the same mistake then try... set values to your ArrayList first and then assign that arrayList to spinner. I declared a global arrayList and set it to spinner first and then add values to it from another method... at that time i faced the same problem. Otherwise you can do notifyDataSetChanged() to your arrayList.
Solution 19:[19]
try this code==>
ArrayAdapter<String> stateNameAdaptor = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1, stateNameList);
stateNameAdaptor.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spnState.setAdapter(stateNameAdaptor);

Wierd. I had the same problem. What I did to make it work : 1. Add some initial data to the list ( ex.--- please select - -) 2. Load the rest of data and add it to the list 3. Call adapter.notifyDatasetChaged()
Solution 21:[21]
In my case the list is populated from firestore before supplied to the adapter construction. The list is already populated and is displayed in spinner. but the size of the list was returned zero. So I only can select the item from the list, but there is no display in the spinner text and unable to call the onitemselected part. I previously made a callback of the querysnapshot and from the snapshot I populated the list. it caused only adding the items to the spinner but cannot be selected. I resolved this by taking a callback of the list instead of the querysnapshot from a repository class and after this my list is populated well and its size is correct and the spinner works fine..my code is attached here.. hope this helps someone...
//interface
public interface SprRbaCallback{
void onSprRbaCallback(List<String> list);
}
//Repository class
public void getRBA(final SprRbaCallback sprRbaCallback){
rbaCollection.get().addOnSuccessListener(new OnSuccessListener<QuerySnapshot>() {
@Override
public void onSuccess(QuerySnapshot queryDocumentSnapshots) {
for(DocumentSnapshot snapshot : queryDocumentSnapshots){
String item = (String) snapshot.get("dealerName");
assert item != null;
Log.d(TAG, item);
list.add(item);
}
Log.d(TAG, String.valueOf(list.size()));
sprRbaCallback.onSprRbaCallback(list);
}
}).addOnFailureListener(new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
Log.d(TAG, e.toString());
}
});
}
// calling method..
private void addItemsToRBASpinner() {
firebaseRepository.getRBA(new FirebaseRepository.SprRbaCallback() {
@Override
public void onSprRbaCallback(List<String> list) {
int size = list.size();
Log.d(TAG + "listsize", String.valueOf(size));
ArrayAdapter<String> sprAdaptSelectRBA = new ArrayAdapter<String>(CreateAccountActivity.this,
R.layout.spinneritem, list);
sprAdaptSelectRBA.setDropDownViewResource(R.layout.rbaspinner_dropdown);
spr_rbaSelect.setAdapter(sprAdaptSelectRBA);
sprAdaptSelectRBA.notifyDataSetChanged();
spr_rbaSelect.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
Log.d("NOBY", "ENTERED ON ITEMSELETED");
txt_selectedRBA = (String) parent.getItemAtPosition(position);
Toast.makeText(parent.getContext(), "Selected RBA: " + txt_selectedRBA, Toast.LENGTH_LONG).show();
Log.d("NOBY", txt_selectedRBA);
}
@Override
public void onNothingSelected(AdapterView<?> parent) {
Log.d("NOBY", "ENTERED NOTHING SELECTED");
txt_selectedRBA = "Dixon";
}
});
}
});
}
This code works fine for me...hope this help someone...:)

You should use the first Spinner to get the values.
Try the following code:
String provider = spinner1.getSelectedItem().toString();
What you are doing is getting the default value of the spinner.
Solution 23:[23]
Try This code
ArrayAdapter<String> arrayAdapte=new ArrayAdapter<String>(this,android.R.layout.simple_spinner_dropdown_item,states);
arrayAdapte.setDropDownViewResource(android.R.layout.simple_list_item_1 );
spinnerState.setAdapter(arrayAdapte);
String data=spinnerState.getSelectedItem().toString(); // this is select particular item from list;
int position=spinnerState.getSelectedItemPosition(); // this return position of data selected in list;
