Here is my code for spinner_style.xml
<item><layer-list>
<item><shape>
<gradient android:angle="90" android:endColor="#B3BBCC" android:startColor="#E8EBEF" android:type="linear" />
<stroke android:width="1dp" android:color="#000000" />
<corners android:radius="4dp" />
<padding android:bottom="3dp" android:left="3dp" android:right="3dp" android:top="3dp" />
</shape></item>
<item ><bitmap android:gravity="bottom|right" android:src="#drawable/spinner_arrow" />
</item>
</layer-list></item>
style.xml
<resources>
<!-- Base application theme. -->
<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="spinner_style">
<item name="android:layout_width">match_parent</item>
<item name="android:layout_height">wrap_content</item>
<item name="android:background">#drawable/spinner_style</item>
<item name="android:layout_margin">10dp</item>
<item name="android:paddingLeft">8dp</item>
<item name="android:paddingRight">20dp</item>
<item name="android:paddingTop">5dp</item>
<item name="android:paddingBottom">5dp</item>
<item name="android:popupBackground">#DFFFFFFF</item>
</style>
And in my activity layout I am using spinner as:
<Spinner
android:id="#+id/spinner"
style="#style/spinner_style" />
But I am not getting the required design. Here is the layout image for the given code. The spinner is covering the whole screen instead of height as wrap_ content:
I need to add change
<item name="android:layout_height">wrap_content</item>
to
<item name="android:layout_height">30dp</item>
in style.xml. Though I still don't know why wrap content is not working here.

I am fairly new to android studio and I am developing a small app.
I have just added my first buttons but I am having trouble selecting the colour of them.
The code i am using in my activity xml is:
<Button
android:id="#+id/signUpButton"
android:text="SIGN UP"
android:textColor="#FFF"
android:textSize="30sp"
android:layout_marginTop="20dp"
android:layout_width="270dp"
android:layout_height="60dp"
android:background="#drawable/buttonshape"
/>
and the code in buttonshape.xml is:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" >
<corners
android:radius="14dp"
/>
<solid
android:color="#FCB1B1"
/>
<padding
android:left="0dp"
android:top="0dp"
android:right="0dp"
android:bottom="0dp"
/>
<size
android:width="270dp"
android:height="60dp"
/>
<stroke
android:width="3dp"
android:color="#FCB1B1"
/>
</shape>
For some reason the button will not take on the colour specified in the buttonshape.xml and instead will take on the style from the themes.xml file
themes.xml:
<resources xmlns:tools="http://schemas.android.com/tools">
<!-- Base application theme. -->
<style name="Theme.Health_Link" parent="Theme.MaterialComponents.DayNight.DarkActionBar">
<!-- Primary brand color. -->
<item name="colorPrimary">#color/salmon</item>
<item name="colorPrimaryVariant">#FFF</item>
<item name="colorOnPrimary">#color/white</item>
<!-- Secondary brand color. -->
<item name="colorSecondary">#color/teal_200</item>
<item name="colorSecondaryVariant">#color/teal_700</item>
<item name="colorOnSecondary">#color/black</item>
<!-- Status bar color. -->
<item name="android:statusBarColor" tools:targetApi="l">?attr/colorPrimaryVariant</item>
<!-- Customize your theme here. -->
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
<item name="android:windowContentTransitions">true</item>
<item name="android:windowDisablePreview">true</item>
</style>
<style name="Theme.Health_Link.NoActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
<style name="Theme.Health_Link.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />
<style name="Theme.Health_Link.PopupOverlay" parent="ThemeOverlay.AppCompat.Light" />
</resources>
I have defined two styles in Style.xml, I want to change the style programmatically for certain conditions, Min SDK version 21
<style name="CheckOutButtonStyle" parent="#style/Widget.AppCompat.Button.Colored">
<item name="android:layout_height">60dp</item>
<item name="android:fontFamily">sans-serif-medium</item>
<item name="android:textSize">16sp</item>
<item name="android:padding">0dp</item>
<item name="android:textColor">#color/white_color</item>
<item name="android:layout_margin">#dimen/general_spacing</item>
</style>
<style name="ScanNextItemSecondaryButtonStyle" parent="#style/Widget.AppCompat.Button.Borderless">
<item name="android:layout_height">wrap_content</item>
<item name="android:fontFamily">sans-serif-medium</item>
<item name="android:stateListAnimator">#null
</item> <!-- remove the shadow, per UI request -->
<item name="android:textSize">16sp</item>
<item name="android:padding">0dp</item>
<item name="android:minHeight">0dp</item>
<item name="android:minWidth">0dp</item>
<item name="android:background">#null</item>
<item name="android:textColor">#color/colorSecondaryAccent</item>
<item name="android:layout_marginBottom">#dimen/general_spacing</item>
</style
1. Create xml in drawable.
\res\drawable\back_button_answer.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" >
<corners android:radius="10dip" />
<!-- background -->
<gradient
android:startColor="#D6D7D6"
android:centerColor="#E2E2E2"
android:centerY="0.75"
android:endColor="#D6D7D6"
android:angle="270"
/>
<stroke android:width="2dip" android:color="#fff"/>
</shape>
2. Button btn.setBackgroundResource(R.drawable.back_button_answer);
I got the following background for an edit text:
edit_text_rounded_white.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape>
<solid android:color="#66c6c6c6"/>
<stroke android:width="0.1dp"
android:color="#66c6c6c6"/>
<corners android:radius="40dp"/>
</shape>
</item>
</selector>
in my styles.xml I define the following:
<style name="editText">
<item name="android:background">#drawable/edit_text_rounded_white</item>
<item name="android:drawablePadding">5dp</item>
<item name="android:paddingBottom">2dp</item>
<item name="android:paddingTop">2dp</item>
<item name="android:paddingLeft">10dp</item>
<item name="android:paddingRight">10dp</item>
<item name="android:textCursorDrawable">#drawable/edit_text_cursor</item>
<item name="colorControlNormal">#color/colorPrimaryDark</item>
<item name="colorControlActivated">#color/transparentWhite50</item>
</style>
When I set the style via: style="#style/editText" for my editTexts it takes the background but doesnt take the colorControl I set. When I set the style via android:theme="#style/editText" it takes the colorControls but doesnt show the background image. I already tried src and windowBackground instead of background in the style file.
Any ideas how achieve both? Showing background and the colorControls?
Split your style into two:
<style name="editTextStyle">
<item name="android:background">#drawable/edit_text_rounded_white</item>
<item name="android:drawablePadding">5dp</item>
<item name="android:paddingBottom">2dp</item>
<item name="android:paddingTop">2dp</item>
<item name="android:paddingLeft">10dp</item>
<item name="android:paddingRight">10dp</item>
<item name="android:textCursorDrawable">#drawable/edit_text_cursor</item>
</style>
<style name="editTextTheme">
<item name="colorControlNormal">#color/colorPrimaryDark</item>
<item name="colorControlActivated">#color/transparentWhite50</item>
</style>
And then apply both to your view:
<EditText
...
android:theme="#style/editTextTheme"
style="#style/editTextStyle"/>
I am trying to implement a spinner with a custom layout (not the spinner item layout), the outer layout. I want it to look like this:
http://imgur.com/a/U6RzU
I searched stackoverflow and google, but couldn't figure out how to come up with this (beside putting the whole picture as a background)
Thanks a lot in advance
Edit
This is what I tried:
styles.xml
<style name="spinner">
<item name="android:layout_marginTop">6dp</item>
<item name="android:layout_marginBottom">6dp</item>
<item name="android:layout_marginLeft">0dp</item>
<item name="android:layout_marginRight">0dp</item>
<item name="android:padding">10dp</item>
<item name="android:background">#drawable/spinner_bg</item>
<item name="android:popupBackground">#color/red</item>
<item name="android:textSize">15sp</item>
</style>
spinner_bg.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<layer-list>
<item>
<shape>
<gradient android:angle="90" android:endColor="#ff0000"
android:startColor="#ff0000" android:type="linear" />
<stroke android:width="0.33dp" android:color="#0fb1fa" />
<corners android:radius="0dp" />
<padding android:bottom="3dp" android:left="3dp" android:right="3dp" android:top="3dp" />
</shape>
</item>
<item android:right="5dp">
<bitmap android:gravity="center_vertical|right" android:src="#drawable/arrow_white_down" />
</item>
</layer-list>
</item>
</selector>
where arrow_white_down is a png of a tiny white arrow (like the one in the link)
I solved it by using a RelativeLayout with the spinner and an image (arrow) beside it, it doesn't look really good in spinnerMode="dropdown" but this is the best I could do
layout
<RelativeLayout
android:id="#+id/spinner_container"
style="#style/spinner_container">
<Spinner
android:id="#+id/spinner"
style="#style/spinner"
android:layout_toLeftOf="#+id/spinner_image"
android:layout_toStartOf="#+id/spinner_image" />
<ImageView
android:id="#+id/spinner_image"
style="#style/spinner_image" />
</RelativeLayout>
styles.xml
<style name="spinner_container">
<item name="android:layout_width">match_parent</item>
<item name="android:layout_height">35dp</item>
<item name="android:orientation">horizontal</item>
<item name="android:layout_marginTop">6dp</item>
<item name="android:layout_marginBottom">6dp</item>
<item name="android:layout_marginLeft">0dp</item>
<item name="android:layout_marginRight">0dp</item>
<item name="android:background">#color/red</item>
</style>
<style name="spinner">
<item name="android:layout_width">match_parent</item>
<item name="android:layout_height">wrap_content</item>
<item name="android:layout_margin">0dp</item>
<item name="android:layout_alignParentLeft">true</item>
<item name="android:layout_alignParentStart">true</item>
<item name="android:padding">5dp</item>
<item name="android:textColor">#color/white</item>
<item name="android:background">#color/red</item>
<item name="android:popupBackground">#color/red</item>
<item name="android:textSize">15sp</item>
</style>
<style name="spinner_image">
<item name="android:layout_width">wrap_content</item>
<item name="android:layout_height">match_parent</item>
<item name="android:layout_margin">5dp</item>
<item name="android:padding">0dp</item>
<item name="android:layout_alignParentRight">true</item>
<item name="android:layout_alignParentEnd">true</item>
<item name="android:adjustViewBounds">true</item>
<item name="android:src">#drawable/bc_spinner_arrow</item>
</style>
where bc_spinner_arrow is a transparent pic of a white arrow and a vertical line (like the one in the question)
I'm trying to change all the TextColor of my buttons in my app to white and also trying to make it bold. But that isn't happening, I'm overwriting the android:Widget.Button
I'm developing for Jelly Bean 4.1.2
What am I doing wrong?
Theme definition in manifest
android:theme="#style/spui" >
The theme where I like to
<style name="spui" parent="android:Theme.Holo.Light.DarkActionBar">
<item name="android:buttonStyle">#style/Buttonspui</item>
</style>
The style for the button itself
<style name="Buttonspui" parent="android:Widget.Button">
<item name="android:background">#drawable/btn_default_holo_light</item>
<item name="android:minHeight">48dip</item>
<item name="android:minWidth">64dip</item>
<item name="android:textColor">#ffffff</item>
<item name="android:textStyle">bold</item>
</style>
The button
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="15dp"
android:text="#string/edit"
android:id="#+id/btnEdit"
style="#style/Buttonspui"/>
For styling your Button you can use this:
Go to the drawable folder and make an XML (e.g. button.xml) file called "style" which contains the following:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape>
<gradient android:startColor="#449def" android:endColor="#2f6699" android:angle="270" />
<stroke android:width="1px" android:color="#000000" />
<corners android:bottomLeftRadius="0dp"
android:bottomRightRadius="0dp"
android:topLeftRadius="8dp"
android:topRightRadius="8dp"/>
<padding android:left="10dp" android:top="10dp" android:right="10dp" android:bottom="10dp" />
</shape>
</item>
</selector>
This is my code, you can make the necessary changes you want
Now call it in your layout XML (mainactivity.xml) like this
android:background="#drawable/button.xml"
Now to change the font color and style you can use the following which comes as part of the styles.xml in the values folder
<style name="buttonStyle" parent="#android:style/Widget.Button.Small">
<item name="android:textColor">#FFFFFF</item>
<item name="android:textSize">12sp</item>
<item name="android:textStyle">bold</item>
</style>
Now call this in the layout XML (mainactivity.xml) like this
style="#style/buttonStyle"
The final code is:
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="15dp"
android:text="#string/edit"
android:id="#+id/btnEdit"
android:background="#drawable/button.xml"
style="#style/buttonStyle"
/>
Hope this helps :)
This will change the default button style for the entire app, include alert dialog button. Adjust the style based on yours.
