How to change spinner text size and text color?
AndroidSpinnerAndroid Problem Overview
In my Android application, I am using spinner, and I have loaded data from the SQLite database into the spinner, and it's working properly. Here is the code for that.
Spinner spinner = (Spinner) this.findViewById(R.id.spinner1);
List<String> list = new ArrayList<String>();
ArrayAdapter<String> dataAdapter = new ArrayAdapter<String> (this,android.R.layout.simple_spinner_item, list);
cursor.moveToFirst();
list.add("All Lists");
if (cursor.getCount() > 0) {
for (int i = 0; i < cursor.getCount(); i++) {
keyList[i] = cursor.getString(cursor.getColumnIndex(AndroidOpenDbHelper.KEYWORD));
list.add(keyList[i]);
cursor.moveToNext();
}
}
Database.close();
cursor.close();
dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(dataAdapter);
Now I want to change the text color and text size of spinner data. I have used following XML lines to my spinner tag on my XML file, but it is not working.
android:textColor="@android:color/white"
android:textSize="11dp"
How can I change the text color and text size of my spinner?
Android Solutions
Solution 1 - Android
Make a custom XML file for your spinner item.
spinner_item.xml:
Give your customized color and size to text in this file.
<?xml version="1.0" encoding="utf-8"?>
<TextView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textSize="20sp"
android:gravity="left"
android:textColor="#FF0000"
android:padding="5dip"
/>
Now use this file to show your spinner items like:
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.spinner_item,list);
You don't need to set the drop down resource. It will take spinner_item.xml only to show your items in spinner.
Solution 2 - Android
Simple and crisp...:
private OnItemSelectedListener OnCatSpinnerCL = new AdapterView.OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {
((TextView) parent.getChildAt(0)).setTextColor(Color.BLUE);
((TextView) parent.getChildAt(0)).setTextSize(5);
}
public void onNothingSelected(AdapterView<?> parent) {
}
};
Solution 3 - Android
If all the spinners may have the same text color for their TextView items, another approach is to use a custom style for spinner dropdown items:
In res/values/styles.xml:
<resources>
<style name="AppBaseTheme" parent="android:Theme.Light">
</style>
<style name="AppTheme" parent="AppBaseTheme">
<item name="android:spinnerDropDownItemStyle">@style/mySpinnerItemStyle</item>
</style>
<style name="mySpinnerItemStyle" parent="@android:style/Widget.Holo.DropDownItem.Spinner">
<item name="android:textColor">@color/my_spinner_text_color</item>
</style>
</resources>
And define your custom color in res/values/colors.xml:
<color name="my_spinner_text_color">#808080</color>
Solution 4 - Android
Here is a link that can help you to change the color of the Spinner:
<Spinner
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="@+id/spinner"
android:textSize="20sp"
android:entries="@array/planets"/>
You need to create your own layout file with a custom definition for the spinner item spinner_item.xml:
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/text1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textSize="20sp"
android:textColor="#ff0000" />
If you want to customize the dropdown list items, you will need to create a new layout file. spinner_dropdown_item.xml:
<?xml version="1.0" encoding="utf-8"?>
<CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/text1"
style="?android:attr/spinnerDropDownItemStyle"
android:maxLines="1"
android:layout_width="match_parent"
android:layout_height="?android:attr/listPreferredItemHeight"
android:ellipsize="marquee"
android:textColor="#aa66cc"/>
And finally another change in the declaration of the spinner:
ArrayAdapter adapter = ArrayAdapter.createFromResource(this,
R.array.planets_array, R.layout.spinner_item);
adapter.setDropDownViewResource(R.layout.spinner_dropdown_item);
spinner.setAdapter(adapter);
That's it.

If you work with android.support.v7.widget.AppCompatSpinner here is the simplest tested solution using styles:
<android.support.v7.widget.AppCompatSpinner
android:id="@+id/spefcialFx"
style="@style/Widget.AppCompat.Spinner.Underlined"
android:layout_width="200dp"
android:layout_height="wrap_content"
android:layout_marginLeft="4dp"
android:theme="@style/Spinner"
android:entries="@array/special_fx_arrays"
android:textSize="@dimen/text_size_normal"></android.support.v7.widget.AppCompatSpinner>
And the style:
<style name="Spinner" parent="Widget.AppCompat.Light.DropDownItem.Spinner">
<item name="android:paddingStart">0dp</item>
<item name="android:paddingEnd">0dp</item>
<item name="android:textColor">@color/white</item>
<item name="android:backgroundTint">@color/red</item>
<item name="android:textSize">14sp</item>
</style>
The only downside is the android:backgroundTint sets color for both the dropdown arrow and the dropdown background.
Solution 6 - Android
To prevent lagging, you need to not only set the text properties in the onItemSelected listener, but also in the Activity's onCreate method (but it's a little tricky).
Specifically, you need to put this in onCreate after setting the adapter:
spinner.setSelection(0, true);
View v = spinner.getSelectedView();
((TextView)v).setTextColor(backgroundColor);
And then put this in onItemSelected:
((TextView) view).setTextColor(backgroundColor);
Here is a full example:
@Override
protected void onCreate(Bundle savedInstanceState)
{
Spinner spinner = (Spinner) findViewById(R.id.spinner);
//Set the choices on the spinner by setting the adapter.
spinner.setAdapter(new SpinnerAdapter(toolbar.getContext(), new String[]{"Overview", "Story", "Specifications", "Poll", "Video"}, accentColor, backgroundColor));
//Set the text color of the Spinner's selected view (not a drop down list view)
spinner.setSelection(0, true);
View v = spinner.getSelectedView();
((TextView)v).setTextColor(backgroundColor);
//Set the listener for when each option is clicked.
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener()
{
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id)
{
//Change the selected item's text color
((TextView) view).setTextColor(backgroundColor);
}
@Override
public void onNothingSelected(AdapterView<?> parent)
{
}
});
}
For more details, see my question.
Solution 7 - Android
If you want the text color to change in the selected item only, then this can be a possible workaround. It worked for me and should work for you as well.
spinner.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
((TextView) spinner.getSelectedView()).setTextColor(Color.WHITE);
}
});
Solution 8 - Android
we can change style of spinner textview set theme for spinner like this:
styles.xml:
<style name="mySpinnerItemStyle" parent="@android:style/Widget.Holo.DropDownItem.Spinner">
<item name="android:textSize">@dimen/_11ssp</item>
<item name="android:textColor">@color/blue</item>
<item name=...</item>
</style>
then
<Spinner
android:theme="@style/mySpinnerItemStyle"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
if you want to change spinner textview attribute programtically:
Programatically:
val textView = (view.getChildAt(0) as TextView)
textView.setTextColor(resources.getColor(R.color.dark_mode))
Solution 9 - Android
For someone who needs only Style way for AppCompat.
Result
styles.xml
<resources>
...
<style name="Spinner" parent="Widget.AppCompat.Light.DropDownItem.Spinner">
<item name="android:paddingStart">0dp</item>
<item name="android:paddingEnd">0dp</item>
<item name="android:textColor">@color/material_grey_700</item>
<item name="android:textSize">12sp</item>
</style>
</resources>
your_spinner_layout.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent" />
...
<android.support.v7.widget.AppCompatSpinner
android:id="@+id/content_spinner"
style="@style/Widget.AppCompat.Spinner.Underlined"
android:layout_width="140dp"
android:layout_height="wrap_content"
android:entries="@array/shipping_tracking_carrier_names"
android:spinnerMode="dropdown"
android:theme="@style/Spinner" />
<EditText
android:id="@+id/content_input"
android:layout_width="140dp"
android:layout_height="wrap_content"
android:inputType="text"
android:maxLines="1"
android:paddingEnd="8dp"
android:paddingStart="8dp"
android:textColor="@color/material_grey_700"
android:textSize="12sp" />
...
</LinearLayout>
Plus
And if you want to set android:entries programmatically with defined style.
Try this.
AppCompatSpinner spinner = findViewById(R.id.content_spinner);
CharSequence[] entries = getResources().getTextArray(R.array.shipping_tracking_carrier_names);
ArrayAdapter<CharSequence> adapter = new ArrayAdapter<>(spinner.getContext(), android.R.layout.simple_spinner_item, entries);
adapter.setDropDownViewResource(android.support.v7.appcompat.R.layout.support_simple_spinner_dropdown_item);
spinner.setAdapter(adapter);
As in the code, using same Context with the Spinner is most important thing.
spinner.getContext()

To change the color of spinner text :
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
((TextView) parent.getChildAt(0)).setTextColor(Color.WHITE);}
Solution 11 - Android
For those who want to change DrowDownIcon color
you can use like this
spinner.getBackground().setColorFilter(Color.parseColor("#ffffff"), PorterDuff.Mode.SRC_ATOP);
Solution 12 - Android
Can change the text colour by overriding the getView method as follows:
new ArrayAdapter<String>(getContext(), android.R.layout.simple_spinner_dropdown_item, list()){
@Override
public View getView(int position, View convertView, @NonNull ViewGroup parent) {
View view = super.getView(position, convertView, parent);
//change the color to which ever you want
((CheckedTextView) view).setTextColor(Color.RED);
//change the size to which ever you want
((CheckedTextView) view).setTextSize(5);
//for using sp values use setTextSize(TypedValue.COMPLEX_UNIT_SP, 16);
return view;
}
}
Solution 13 - Android
Just wanted to make a small change on the correct answer at the top. Make a custom XML file for your spinner item inside the layout directory.
spinner_style.xml:
Give your customized color and size to text in this file.
<?xml version="1.0" encoding="utf-8"?>
<TextView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
style="?android:attr/spinnerItemStyle"
android:singleLine="true"
android:ellipsize="marquee"
android:textAlignment="inherit"
android:textSize="15sp"
android:textColor="#FF0000"
android:padding="5dp"
/>
Now use this file to show your spinner items inside your java file:
ArrayAdapter<String> adapter = new ArrayAdapter<>(this,R.layout.spinner_style,list);
adapter.setDropDownViewResource(R.layout.spinner_style);
Solution 14 - Android
Rather than making a custom layout to get a small size and if you want to use Android's internal small size LAYOUT for the spinner, you should use:
"android.R.layout.simple_gallery_item" instead of "android.R.layout.simple_spinner_item".
ArrayAdapter<CharSequence> madaptor = ArrayAdapter
.createFromResource(rootView.getContext(),
R.array.String_visitor,
android.R.layout.simple_gallery_item);
It can reduce the size of spinner's layout. It's just a simple trick.
If you want to reduce the size of a drop down list use this:
madaptor.setDropDownViewResource(android.R.layout.simple_gallery_item);
Solution 15 - Android
The easiest way to re-use/change the android.R.layout resources is just go the definition. In Android Studio, do Ctrl + B on android.R.layout.simple_spinner_item.xml.
It will take you to the resource file. Just copy the resource file and add a new layout in your Package.R.layout folder and change the textColor of textview as you like and then just call it in adapter like this:
ArrayAdapter<String> adapter = new ArrayAdapter<String(Context,R.layout.spinner_item, spinnerlist);
Solution 16 - Android
Simplest: Works for me
TextView spinnerText = (TextView) spinner.getChildAt(0);
spinnerText.setTextColor(Color.RED);
Solution 17 - Android
If you want a simple method, in order to add items to a dropdown, you usually add them to the strings.xml. Here is an example on how to add colour by using the strings.xml file:
<string-array name="age_array">
<item> 0-6 </item> //No custom colour
<item><font fgcolor='#FF4CD964'> 12+ </font></item> //With custom colour
</string-array>
Solution 18 - Android
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/text1"
style="?android:attr/spinnerItemStyle"
android:singleLine="true"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textColor="#fff"
android:ellipsize="marquee"
android:textAlignment="inherit"/>
just use this:
ArrayAdapter<String> adapter_category = new ArrayAdapter<String>(this,
R.layout.spinner_list_item, categories);
adapter_category
.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
Solution 19 - Android
Another variation of Ashraf's solution would be to make sure you're taking into account screen sizes. You'll need to get the spinner in onCreate and set the listener after you set the adapter:
//set your adapter with default or custom spinner cell, then://
serverSpinner.setOnItemSelectedListener(spinnerSelector);
serverSpinner.setSelection(defaultServer);
Then you can start changing the text size of the view that's showing before the spinner is clicked:
private AdapterView.OnItemSelectedListener spinnerSelector = new AdapterView.OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {
boolean tabletSize = getResources().getBoolean(R.bool.isTablet);
boolean largeTablet = getResources().getBoolean(R.bool.isLargeTablet);
if (tabletSize) { ((TextView)parent.getChildAt(0)).setTextSize(16); }
else if (largeTablet) { ((TextView)parent.getChildAt(0)).setTextSize(18); }
else { ((TextView)parent.getChildAt(0)).setTextSize(12); }
}
public void onNothingSelected(AdapterView<?> parent) {
}
};
All you need to do is create layout specific folders like this:
> values-sw360dp > > values-sw600dp > > values-sw800dp
an then add an xml file named "bool.xml" into each of those folders:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<bool name="isTablet">false</bool>
<bool name="isLargeTablet">false</bool>
</resources>
Solution 20 - Android
First we have to create the simple xml resource file for the textview like as below:
<?xml version="1.0" encoding="utf-8"?>
<TextView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textSize="20sp"
android:gravity="left"
android:textColor="#FF0000"
android:padding="5dip"
/>
and save it. after set on your adapterlist.
Solution 21 - Android
Try this method. It is working for me.
@Override
public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
TextView textView = (TextView) view;
((TextView) adapterView.getChildAt(0)).setTextColor(Color.RED);
((TextView) adapterView.getChildAt(0)).setTextSize(20);
Toast.makeText(this, textView.getText()+" Selected", Toast.LENGTH_SHORT).show();
}
Solution 22 - Android
you can have this type of adapter for spinner, totally customized:
ArrayAdapter<String> genderAdapter = new ArrayAdapter<String>(getActivity(), R.layout.spinner_text, genderList) {
public View getView(int position, View convertView, ViewGroup parent) {
View v = super.getView(position, convertView, parent);
((TextView) v).setTextSize(TypedValue.COMPLEX_UNIT_DIP, 16);
((TextView) v).setTextColor(Color.parseColor("#676767"));
((TextView) v).setTypeface(vrFont);
return v;
}
public View getDropDownView(int position, View convertView, ViewGroup parent) {
View v = super.getDropDownView(position, convertView, parent);
((TextView) v).setTextSize(TypedValue.COMPLEX_UNIT_DIP, 16);
((TextView) v).setTypeface(vrFont);
((TextView) v).setTextColor(Color.parseColor("#676767"));
if (position == 0) {
((TextView) v).setTextColor(Color.parseColor("#979797"));
}
return v;
}
while R.layout.spinner_text is:
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/text1"
style="?android:attr/spinnerItemStyle"
android:layout_width="fill_parent"
android:layout_height="40dp"
android:gravity="center_vertical|left"
android:ellipsize="marquee"
android:maxLines="1"
android:textColor="@color/whiteThree" />
Solution 23 - Android
String typeroutes[] = {"Select","Direct","Non Stop"};
Spinner typeroute;
typeroute = view.findViewById(R.id.typeroute);
final ArrayAdapter<String> arrayAdapter5 = new ArrayAdapter<String>(
getActivity(), android.R.layout.simple_spinner_item, typeroutes) {
@Override
public boolean isEnabled(int position) {
if (position == 0) {
// Disable the first item from Spinner
// First item will be use for hint
return false;
} else {
return true;
}
}
public View getView(int position, View convertView, ViewGroup parent) {
View v = super.getView(position, convertView, parent);
((TextView) v).setTextSize(TypedValue.COMPLEX_UNIT_DIP, 16);
((TextView) v).setTextColor(Color.parseColor("#ffffff"));
return v;
} ---->in this line very important so add this
@Override
public View getDropDownView(int position, View convertView,
ViewGroup parent) {
View view = super.getDropDownView(position, convertView, parent);
TextView tv = (TextView) view;
if (position == 0) {
// Set the hint text color gray
tv.setTextColor(Color.GRAY);
} else {
tv.setTextColor(Color.BLACK);
}
return view;
}
};
arrayAdapter5.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
typeroute.setAdapter(arrayAdapter5);
that's all enjoy your coding...

I have done this as following.I have use getDropDownView() and getView() methods.
Use getDropDownView() for opened Spinner.
@Override
public View getDropDownView(int position, View convertView, ViewGroup parent) {
View view = convertView;
if (view == null) {
LayoutInflater vi = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = vi.inflate(R.layout.context_row_icon, null);
}
TextView mTitle = (TextView) view.findViewById(R.id.context_label);
ImageView flag = (ImageView) view.findViewById(R.id.context_icon);
mTitle.setText(values[position].getLabel(activity));
if (!((LabelItem) getItem(position)).isEnabled()) {
mTitle.setTextColor(activity.getResources().getColor(R.color.context_item_disabled));
} else {
mTitle.setTextColor(activity.getResources().getColor(R.color.context_item));
}
return view;
}
And Use getView() for closed Spinner.
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = convertView;
if (view == null) {
LayoutInflater vi = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = vi.inflate(R.layout.context_row_icon, null);
}
TextView mTitle = (TextView) view.findViewById(R.id.context_label);
ImageView flag = (ImageView) view.findViewById(R.id.context_icon);
mTitle.setText(values[position].getLabel(activity));
mTitle.setTextColor(activity.getResources().getColor(R.color.context_item_disabled));
return view;
}
Solution 25 - Android
just add new style like this:
<style name="mySpinnerItemStyle" parent="ThemeOverlay.AppCompat.Dark">
<item name="android:textColor">#000</item>
<item name="android:color">#000</item>
</style>
and use it:
<Spinner
android:id="@+id/spinnerCategories"
android:layout_width="match_parent"
android:layout_height="wrap_content"
style="@style/mySpinnerItemStyle"
android:layout_margin="5dp" />
