I've recently been looking into customizing the divider colour between items in a Spinner's drop down list, and I found the way to do it for all spinners at once via the application theme. For example:
<style name="custom_divider">
<item name="android:divider">#FFFFFF</item>
<item name="android:dividerHeight">5dp</item>
</style>
<style name="holo_light_dark_action_bar_custom_dropdown" parent="#android:style/Theme.Holo.Light.DarkActionBar">
<item name="android:dropDownListViewStyle">#style/custom_divider</item>
</style>
What I want to do is style the dividers for one specific spinner (in this case, the spinner in the action bar), rather than all spinners. I haven't seen any solutions for that, so I'm hoping it's something obvious and that I just missed it. :)

I want to change the color of the selected area in the bottom navigation view material 3, but the color does not change in any way. I've tried selector, background, background Tint, and styles. All unsuccessfully.
Currently like this.
It should be like this.
You can change indicator color by overridng it's default style.
Default itemIndicatorStyle :
<style name="Widget.Material3.BottomNavigationView.ActiveIndicator" parent="">
<item name="android:width">#dimen/m3_bottom_nav_item_active_indicator_width</item>
<item name="android:height">#dimen/m3_bottom_nav_item_active_indicator_height</item>
<item name="marginHorizontal">#dimen/m3_bottom_nav_item_active_indicator_margin_horizontal</item>
<item name="shapeAppearance">#style/ShapeAppearance.Material3.NavigationBarView.ActiveIndicator</item>
<item name="android:color">?attr/colorSecondaryContainer</item>
just override the style according to your preference :
<style name="App.Custom.Indicator" parent="Widget.Material3.BottomNavigationView.ActiveIndicator">
<item name="android:color">#color/blue</item>
</style>
And then add this line to your bottomNavigationView xml code :
app:itemActiveIndicatorStyle="#style/App.Custom.Indicator"
you can use this function for change indicator color:
findViewById<BottomNavigationView>(R.id.bottomNavigationView) .itemActiveIndicatorColor = getColorStateList(R.color.white)
and set this annotatin for your onCreate function #RequiresApi(Build.VERSION_CODES.M)
look in the screenshot
I'm struggling to set the right style for my button in the project. I don't know why shapeAppearance not working. Even if I use only cornerSize it's not working.
I have a base style for a button:
<style name="SnButton" parent="Widget.MaterialComponents.Button.UnelevatedButton">
<item name="shapeAppearance">#style/MyShapeAppearance</item>
<item name="backgroundTint">#null</item>
</style>
This is my shape appearance for a button:
<style name="MyShapeAppearance" parent="ShapeAppearance.MaterialComponents.SmallComponent">
<item name="cornerFamily">rounded</item>
<item name="cornerSize">2dp</item>
</style>
This is my base theme: Theme.MaterialComponents.Light.NoActionBar.Bridge
What should I do to force shapeAppearance work in my case? Or at least cornerSize?
I figured out why style was not working!
The problem was in the way I set the color for the button. I've used android:background, but backgroundTint must be used.
I've been searching for a while now for a way to fix this and haven't even found a similar issue. I'm using the basic activity template from Android Studio which uses a toolbar instead of an action bar. When I run the app, everything looks as it should, activities have their title, up arrow and icons. But the design preview only shows an empty toolbar. I haven't messed with anything that came predefined in the template, so styles are the following:
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
</style>
<style name="AppTheme.NoActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
In the manifest, style/AppTheme is automatically applied to the application, and style/AppTheme.NoActionBar to each activity that was created using the basic activity template. In the design preview, which is using by default the AppTheme.NoActionBar theme, I see an empty toolbar like this:
If I change the theme to AppTheme, the title and up arrow shows, but there is then an empty toolbar below:
How do I make the toolbar show only once and with title and icons in the design preview?
Does anyone know how can I change this green color that appears in my editText ?
I would like to do it from the layout XML if it is possible
just below the editText image.
Any help is appreciated.
I could resolve it adding: android:backgroundTint="#color/color_you_wat" to the EditText in the layout file
Programmatically:
editText.getBackground().mutate().setColorFilter(getResources().getColor(R.color.your_color), PorterDuff.Mode.SRC_ATOP);
Using theme:
<style name="AppThem" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- change values below to make same eefect for all EditTexts ->
<item name="colorControlNormal">#c5c5c5</item>
<item name="colorControlActivated">#color/accent</item>
<item name="colorControlHighlight">#color/accent</item>
</style>
<!-- also you can create different styles with values above for many different views ->
Edit:
You can always use in xml file:
"app:backgroundTint="#color/myColor" in xml.
Don't use android:. Otherwise you would lose backward compability with Android 4.4 and older.
Hope it help
Given the following style in file: res/values/styles.xml
<style name="GiftCardFragment.TitleLLLabelTV">
<item name="android:paddingStart">5dp</item>
<item name="android:paddingLeft">5dp</item>
</style>
android:paddingStart is only valid in Android platform 17 and above, so then I would create a new styles.xml file in "res/values-v17/styles.xml".
But the question is: Do I have to repeat the whole style, or could I just add the styles I want to add extra (alternatively override) for a given platform and above in "res/values-v17/styles.xml"? Like:
<style name="GiftCardFragment.TitleLLLabelTV">
<item name="android:paddingStart">5dp</item>
</style>
And then Android would merge then at runtime. Am I correct? Any pointing in right direction appreciated, I couldnt find documentation really covering this case.
