I using listviews and expandedviews that has dividers and I can set them but on spinner its looks like it is no divider between items.
Someone that has a idea of how to fix this?
This worked for me:
<style name="SpinnerStyle" parent="Widget.AppCompat.ListView.DropDown">
<item name="android:divider">#d1d1d1</item>
<item name="android:dividerHeight">0.5dp</item>
</style>
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="android:dropDownListViewStyle">#style/SpinnerStyle</item>
The advantage of using this is that it doesn't remove the ripple effect on hover.
I managed to find a more proper solution for this issue (without including the divider in the single item layout).
What you have to do is define in your activity's theme
<item name="android:dropDownListViewStyle">#style/App.Style.Spinner</item>
and then create the proper style with
<style name="App.Style.Spinner" parent="#style/Widget.Sherlock.Light.ListView.DropDown">
<item name="android:dividerHeight">10dip</item>
<item name="android:divider">#drawable/mydivider</item>
</style>
Based on #Talihawk answer, I made it work for specific spinner only. Instead of setting your activity theme, set the theme directly for the spinner view:
<style name="MatchSpinnerStyle" parent="android:style/Widget.ListView.DropDown">
<item name="android:divider">#123456</item>
<item name="android:dividerHeight">1dp</item>
</style>
<style name="MatchSpinnerTheme" parent="AppTheme">
<item name="android:dropDownListViewStyle">#style/MatchSpinnerStyle</item>
</style>
and
<android.support.v7.widget.AppCompatSpinner
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/MatchSpinnerTheme"/>
Sorry, I am answering years after the question was asked but the solution is very simple, you just have to do a simple thing.
Go to your style.xml file and add this item in your active theme
<item name="android:dropDownListViewStyle">#style/MySpinner</item>
after this add another theme with the name MySpinner and same parent of your active theme
<style name="MySpinner" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="android:dividerHeight">2dp</item>
<item name="android:divider">#000</item>
</style>
this will separate your single item and will not show the separator while we hover on a single item
but be sure while doing this, we are applying this theme on all the spinner in the activity. Now after every spinner is will work on this same spinner theme.
For people with same problem i after almost gived up i got an idea of how to get the divider.
I added the divider line at the bottom of my custom layout for each item
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout android:id="#+id/RelativeLayout01"
android:layout_width="fill_parent" android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android" style="#style/ListItem2">
<TextView android:id="#+id/Text" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:layout_alignParentLeft="true"
style="#style/SpinnerView_Text" android:paddingLeft="10dip" />
<ImageView android:id="#+id/icon" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:src="#drawable/arrowright"
android:layout_alignParentRight="true" android:layout_centerInParent="true"
android:layout_marginRight="20dip" />
</RelativeLayout>
<ImageView android:id="#+id/Divider1" android:layout_width="fill_parent"
android:layout_height="1dip" style="#style/Divider"></ImageView>
None of the other solutions worked for me, so I used a drawable as the background of the Spinner items to produce the desired effect.
I have created a new Drawable dropdown_divider.xml and a custom SpinnerAdapter class where I adapted the getDropDownView() method to set the background to the Spinner items.
The android:bottom="-56dp" in the drawable is what centers the line perfectly between two items for me, but that depends on the exact margins and paddings that you've applied in your layout.
dropdown_divider.xml:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:left="16dp"
android:right="16dp"
android:bottom="-56dp">
<shape android:shape="line" >
<stroke
android:width=".2dp"
android:color="#FF666666" />
</shape>
</item>
</layer-list>
SpinnerAdapter:
#Override
public View getDropDownView(int position, View convertView,
#NonNull ViewGroup parent) {
TextView text = (TextView) super.getDropDownView(position, convertView, parent);
text.setBackground(context.getDrawable(R.drawable.dropdown_divider));
label.setTextColor(Color.BLACK);
label.setText(lists.get(position).getTitle());
return text;
}
The result looks like this:

I have apply an style to my EditText to change bottom line when no selected, I do it like this:
<style name="JoinMeetingEditText" parent="Widget.AppCompat.EditText">
<item name="colorControlNormal">#color/edit_text_no_selected_color</item>
<item name="android:textCursorDrawable">#null</item>
<item name="android:theme">#style/JoinMeetingEditText</item>
</style>
But the cursor in the EditText is displayed like this
If I remove <item name="android:theme">#style/JoinMeetingEditText</item> then that line is not displayed but my edit text doesn't display correct color when no selected
This is how I definde EditText in XMl
<android.support.design.widget.TextInputLayout
style="#style/JoinMeetingTextInputLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<EditText
android:id="#+id/email"
android:theme="#style/JoinMeetingEditText"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Email"
android:inputType="number"
android:textColor="#color/white"
android:textSize="16sp">
<requestFocus />
</EditText>
You can create custom drawable like this
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_pressed="true"
android:color="#color/colorAccent"
/> <!-- pressed -->
<item
android:state_focused="true"
android:color="#color/colorPrimary"
/> <!-- focused -->
<item
android:drawable="#android:drawable/edittext_normal"
/> <!-- default -->
</selector>
use this custom style into background of that edittext. This may help you.
Change parent of your custom theme on global "AppTheme" like this:
parent="AppTheme"
or common theme, for example:
parent="Theme.AppCompat.Light.NoActionBar"
In your case custom theme is used as theme for all EditText child views (including cursor view). When you set AppTheme as parent, it overlap special attributes for cursor view over EditText attributes.
I hope this helps you.
I had the same issue. Here's how I solved it: https://stackoverflow.com/a/44036429/1439957
P.S. I recommend using a TextInputEditText as the child of your TextInputLayout instead of an EditText since TextInputEditTexts were specifically designed for this.
Here is The Code :
spinner.xml :
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/spinner"
android:layout_width="match_parent"
android:layout_height="40dp"
android:maxLines="1"
android:gravity="center"
android:singleLine="true"
android:textColor="#FFFFFF"
android:textSize="12sp" />
Spinner :
<Spinner
android:id="#+id/spinner"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center" />
Java :
array = new ArrayAdapter<String>(Activity.this,
R.layout.spinner, ArrayList);
array .setDropDownViewResource(R.layout.spinner);
Spinner.setAdapter(array );
Spinner.setOnItemSelectedListener(this);
Problem : Text is still Aligned to the Left
Use following tag on spinner
android:textAlignment="center"
Simply add in your default app theme style this two lines :
<item name="android:spinnerItemStyle">#style/spinnerItemStyle</item>
<item name="android:spinnerDropDownItemStyle">
#style/spinnerDropDownItemStyle
</item>
create the new style :
<style name="spinnerItemStyle">
<item name="android:gravity">center</item>
</style>
<style name="spinnerDropDownItemStyle">
<item name="android:gravity">center</item>
</style>
Thats it !
Note that the base theme used here is : Theme.AppCompat.Light and this will be applied as the default spinner styles in your app.
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/textView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:ellipsize="marquee"
android:textAlignment="center"
android:textSize="17sp"
tools:ignore="MissingPrefix" />
Use this Textview as the layout passed to your adapter.
android:textAlignment="center" this line is the one who makes the magic
Add this line in your Spinner,
android:textAlignment="center"
Done!
I've followed this : http://nevescheng.blogspot.fr/2013/05/spinner-with-item-text-aligned-to-center.html & this worked fine
I've noticed that i had another spinner xml in value-v11 Folder & this one was Not Modified, i've Modified it & its worked
In your layout add "theme" attribute in Spinner like -
<Spinner
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_marginTop="#dimen/_10sdp"
android:theme="#style/CustomSpinnerTheme"
android:entries="#array/entries"
android:gravity="center"
/>
and add style (in values/style file) -
<!-- Spinner style -->
<style name="CustomSpinnerTheme">
<item name="android:textSize">#dimen/_15ssp</item>
<item name="android:textColor">#color/textMainColor</item>
<item name="android:gravity">center</item>
<item name="android:textAlignment">center</item>
</style>
Enjoy :)
The best answer and was tested is by Mouloud, but in Marshmallow I had to add textAlignment to make the drop down list items centered. So, the full code based in Mouloud code is:
<!-- Spinner style -->
<style name="spinnerItemStyle">
<item name="android:textColor">#color/colorAccent</item>
<item name="android:gravity">center</item>
<item name="android:textAlignment" tools:targetApi="jelly_bean_mr1">center</item>
</style>
<!-- Spinner style drop down style-->
<style name="spinnerDropDownItemStyle">
<item name="android:textColor">#color/colorPrimaryDark</item>
<item name="android:gravity">center</item>
<item name="android:textAlignment" tools:targetApi="jelly_bean_mr1">center</item>
</style>
And add the style now to your theme style:
<!-- Change the spinner style-->
<item name="android:spinnerItemStyle">#style/spinnerItemStyle</item>
<item name="android:spinnerDropDownItemStyle">#style/spinnerDropDownItemStyle</item>
#Override
public View getView(int position, View convertView, ViewGroup parent) {
TextView label = new TextView(context);
label.setText(myObjs[position].getText());
label.setGravity(Gravity.CENTER);
return label;
}
#Override
public View getDropDownView(int position, View convertView,
ViewGroup parent) {
TextView label = new TextView(context);
label.setText(myObjs[position].getText());
label.setGravity(Gravity.CENTER);
return label;
}
PROBLEM
I've tried to change the select highlight in my application but with no luck.
I've been doing it via styles because I have quite a lot of them in my app.
I would be grateful if you have told me what is wrong with my code.
CODE
<style name="AppTheme" parent="android:Theme.Holo.Light">
<item name="android:actionBarStyle">#style/MyActionBar</item>
<item name="android:actionOverflowButtonStyle">#style/MyActionBar</item>
<item name="android:imageButtonStyle">#style/MyImgBtn</item>
<item name="android:spinnerDropDownItemStyle">#style/mySpinnerItemStyle</item>
<item name="android:spinnerStyle">#style/MySpinnerTheme</item>
<item name="android:windowBackground">#android:color/white</item>
</style>
<style name="MySpinnerTheme" parent="android:Widget.Holo.Light.Spinner">
<item name="android:activatedBackgroundIndicator">#drawable/custom_activated_background</item>
</style>
UPDATE
So I've managed to merge two selectors with setting style on setDropDownViewResource layout element. But what I get at the moment are two selectors appearing at the same time.
I've tried to set android:dropDownSelector="#android:color/transparent" on Spinner in XML but still no luck. Posting more code below.
SPINNER
final Spinner yearSpinner = (Spinner) rootView.findViewById(R.id.yearSpinner);
ArrayAdapter<SpinnerItem> adapterYear = new ArrayAdapter<SpinnerItem>(getActivity(),
R.layout.spinner_item_layout , yearsItems);
yearSpinner.setOnItemSelectedListener(itemSelectedListener);
yearSpinner.setAdapter(adapterYear);
<Spinner
android:id="#+id/yearSpinner"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:dropDownSelector="#android:color/transparent"
android:layout_below="#id/yearTxt"
android:layout_marginLeft="20dp"
android:popupBackground="#drawable/podpowiedzi"
android:layout_marginRight="20dp"
android:layout_centerHorizontal="true"
>
</Spinner>
SPINNER_ITEM_LAYOUT
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/text1"
style="#style/mySpinnerItemStyle"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:ellipsize="marquee"
android:singleLine="true"
android:textStyle="italic"
android:textAlignment="inherit"
android:textColor="#color/text_color"
>
</TextView>
To change the style and colours of your spinner drop down items add the following to your style.xml
<style name="mySpinnerItemStyle" parent="#style/android:Theme.Holo">
<item name="android:background">#drawable/spinner_selector</item>
<item name="android:gravity">center_vertical</item>
</style>
And then create the "spinner_selector.xml" in your drawable folder:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:state_checked="true" android:drawable="#color/orange" /> <!-- current selected -->
<item android:state_pressed="true" android:drawable="#color/orange_bright" />
<item android:drawable="#android:color/transparent" />
</selector>
If you want to custom highlight colour when you press on the spinner, we need 9 patch images for spinner backgrounds. Do the following steps:
1) visit this website:http://android-holo-colors.com/, select Spinner, select the colour you want for your spinner highlight and download the zip file. (there are many other options depends on your app)
2) In the zip file open res-->drawable and save file "apptheme_spinner_background_holo_light.xml" to your drawable folder
3) save the following images in the right drawable folders:
apptheme_spinner_default_holo_light.9.png
apptheme_spinner_disabled_holo_light.9.png
apptheme_spinner_focused_holo_light.9.png
apptheme_spinner_pressed_holo_light.9.png
4) add this to your style.xml file:
<style name="MySpinnerTheme" parent="#android:Widget.Holo.Light.Spinner">
<item name="android:background">#drawable/apptheme_spinner_background_holo_light</item>
</style>
In future, you can auto generate any style you want with all the resources required (including spinner highlight colour) thr this website:

I'm trying to create a theme for my first Android app, and it is driving me round the bend. I finally managed to figure out how to style items in a dropdown list, but now I can't change the colour of the divider between list items. I have searched similar questions on stackoverflow, and tried dozens of combinations, but nothing seems to work.
Here is my styles.xml file (abbreviated for clarity):
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="MyTheme" parent="android:Theme.Light">
<item name="android:spinnerStyle">#style/spinnerStyle</item>
<item name="android:spinnerDropDownItemStyle">#style/spinnerDropDownItemStyle</item>
<item name="android:dropDownListViewStyle">#style/spinnerListViewStyle</item>
</style>
<style name="spinnerStyle" parent="#android:style/Widget.Spinner">
<item name="android:background">#drawable/my_theme_spinner</item>
</style>
<style name="spinnerDropDownItemStyle" parent="#android:style/Widget.DropDownItem.Spinner">
<item name="android:background">#drawable/my_theme_spinner_item</item>
<item name="android:paddingLeft">5dp</item>
<item name="android:gravity">center_vertical</item>
</style>
<style name="spinnerListViewStyle" parent="#android:style/Widget.ListView.DropDown">
<item name="android:height">3dp</item>
<item name="android:dividerHeight">3dp</item>
<item name="android:divider">#color/divider</item>
</style>
</resources>
No matter what I do, I just get a 1dp light grey divider between items (which can barely be seen with my light coloured list item background) - neither the height nor colour of the divider is ever affected (I also tried setting it to a drawable, also with no effect). What am I doing wrong?
I have a very simple Activity with the Spinner and it works for the following. The only difference I see is that you have a <item name="android:height">3dp</item> and I don't have that at all.
<style name="TestSpinnerStyle" parent="android:style/Widget.ListView.DropDown">
<item name="android:divider">#ff0000</item>
<item name="android:dividerHeight">5dp</item>
</style>
<style name="SampleTheme" parent="#android:style/Theme.Holo.Light">
<item name="android:dropDownListViewStyle">#style/TestSpinnerStyle</item>
</style>
and in my Activity I have:
Spinner spinner = (Spinner) findViewById(R.id.spinner);
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_dropdown_item_1line);
spinner.setAdapter(dataAdapter);
and then for the main layout I have the following XML:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Hello World, StylingActivity"
/>
<Spinner android:id="#+id/spinner"
android:layout_width="250dp"
android:layout_height="40dp"
/>
</LinearLayout>
Here is the screenshot
If you can't get it to work from there, I can push up the entire thing to a github repo for you.
You could add a horizontal line to the dropdown layout you use, which would effectively create a divider.
EDIT
Some further searching found this:
SO Answer
Which basically says what you show you are trying to do above should work... although it mentions setting that style in your activity theme and you don't mention doing that.
You can do it in your layout.xml
<Spinner
android:id="#+id/sp_to_create"
android:layout_width="match_parent"
android:layout_height="32dp"
android:layout_marginBottom="10dp"
style="#style/spinner_style"
android:prompt="#string/to_type_prompt" />
XML STYLES ADD it
<style name="spinner_style" parent="Widget.AppCompat.ListView.DropDown">
<item name="android:divider">#d1d1d1</item>
<item name="android:dividerHeight">0.5dp</item>
</style>
Add to your Activity Theme
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="android:dropDownListViewStyle">#style/spinner_style</item>
</style>
JAVA FILE
your_spinnerList.setAdapter(new ArrayAdapter<>(getActivity(), android.R.layout.simple_dropdown_item_1line, timeOff_type_list));
Let me know if it had been useful for you! Have a nice day!
The style method in the accepted answer works well until you need two spinners with different divider colors.
Here is what I found works as an alternative:
a) Set the popupBackgroundColor attribute on the spinner to the color you want for the divider. This will color the entire list item's background (including the space we think of as the divider).
b) Set the spinners adapters dropDownViewResource to be a CheckedTextView with it's background attribute set to some other color (or a selector if you want the selected items to have a different color). This will override the color we set in step a for everything but the divider. effectively giving us the desired result.
So you will have:
drawable/spinner_dropdown_background_selector:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#color/your_unchecked_color" android:state_checked="false"/>
<item android:drawable="#color/your_checked_color" android:state_checked="true"/>
<item android:drawable="#color/your_unchecked_color"/>
</selector>
layout/drop_down_item.xml:
<?xml version="1.0" encoding="utf-8"?>
<CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/text1"
android:background="#drawable/spinner_dropdown_background_selector"
android:textColor="#android:color/white"
android:singleLine="true"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ellipsize="marquee" />
Your spinner definition:
<Spinner
...
android:popupBackground="#color/your_divider_color"
...
/>
And finally your array adapter definition:
ArrayAdapter<String> dataAdapter = new ...
dataAdapter.setDropDownViewResource(android.R.layout.drop_down_item);
spinner.setAdapter(dataAdapter);
Please note that setting the popupBackgroundColor has no effect if the spinner is in dialog mode.
When I click on the list item in Android, I always get a blue background. Event if I use a custom layout, when I click, maybe 2-5dp space around my layout is blue. Also, the text views get darker. How can I disable any changes in view when clicking on the list item?
I know its kind of late, but one can also use the setSelector method of the listview and set it to android.R.color.transparent. You can also use android:listSelector in the layout file to achieve the same result.
Create custom theme for your application in /res/values/themes.xml:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<!-- application theme -->
<style name="CustomTheme" parent="android:style/Theme.Light">
<!-- widget styles -->
<item name="android:listViewStyle">#style/ListView</item>
</style>
<!-- list view -->
<style name="ListView" parent="#android:style/Widget.ListView">
<item name="android:background">#ffffff</item>
<item name="android:cacheColorHint">#ffffff</item>
<item name="android:divider">#cccccc</item>
<item name="android:dividerHeight">1px</item>
<item name="android:listSelector">#drawable/list_selector_background</item>
<item name="android:fadingEdge">none</item>
</style>
</resources>
In your AndroidManifest.xml specify the theme:
<application
...
android:theme="#style/CustomTheme" >
You can simply set the android drawSelectorOnTop attribute to false on your ListView and there will not be any background when you click on an item.
Eg:
<ListView android:layout_width="fill_parent" android:layout_height="fill_parent"
android:drawSelectorOnTop="false"/>
Use this
<ListView
android:listSelector="#android:color/transparent"
android:cacheColorHint="#android:color/transparent"
/>
For more details you can visit here
http://developer.android.com/reference/android/widget/ListView.html
I did it Like this:
<ListView
android:listSelector="#android:color/transparent"
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
