I want to add a white stroke to black text inside a button. I can figure out to do this with regular textview but not when it comes to a button.
Thi is regarding Xml android studio btw.
activity_main.xml:
<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="5dip"
android:background="#drawable/login_button_style"
android:text="Log Ind"
android:id="#+id/button"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_alignRight="#+id/editTextPass"
android:layout_alignEnd="#+id/editTextPass"
android:clickable="true" /><![CDATA[
/>
login_button_style.xml:
<shape xmlns:android="http://schemas.android.com/apk/res/android"

android:bottomLeftRadius="15dp"
android:topLeftRadius="15dp"
android:topRightRadius="15dp"/>
<stroke android:color="#d10f0f" android:width="3dp" />

</resources>
can someone please enlighten me?
Look at this answer to a similar question on how to make a border. He creates a new file that is a shape of just that color then stores it as a drawable to be used as the background image
https://stackoverflow.com/questions/7690416/android-border-for-button
Just change the color to white and there you go
EDIT:
Actually seeing now. You want the letters to be outlined in white.
So my best guess would be to draw the entire image with the text and border up in Photoshop/Sketch. And then save that as a drawable. To set for your buttons background. Make sure to set the buttons text to just quotes since you will already have the text in the Photoshop mockup
android:text = ""

I want to customize my searchview edittext which expanded when I click on searchview icon to be like this image
And I tried the custom style to do that but I got this result in this image
The problems:
There is a blue vertical bar at the start of the edittext I need to remove it and make it appears only on a search query and after the querytext also I want to change the color of this vertical bar
I need to add a white search icon with specific padding of the hint and text query currently the white icon in the result screen disappears on search query
How I got this result?
I define searchViewStyle
<style name="SearchViewStyle" parent="Widget.AppCompat.SearchView">
<item name="searchIcon">#drawable/ic_baseline_dark_search_24</item>
<item name="closeIcon">#null</item>
<item name="goIcon">#drawable/ic_baseline_dark_search_24</item>
<item name="commitIcon">#drawable/ic_baseline_dark_search_24</item>
<item name="android:editTextColor">#color/white</item>
<item name="android:textColorHint">#color/white</item>
<item name="android:textColorHighlight">#color/red</item>
<item name="queryBackground">#drawable/radius_drawable</item>
<item name="searchHintIcon">#drawable/ic_baseline_search_24</item>
<item name="queryHint">"search_hint"</item>
</style>
I define searchview like this in my fragment layout
<androidx.appcompat.widget.SearchView
android:id="#+id/searchView"
style="#style/SearchViewStyle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="8dp"
android:layout_marginEnd="8dp"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toTopOf="parent">
</androidx.appcompat.widget.SearchView>
I define a custom drawable background for searchview
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" >
<corners
android:radius="18dp"
/>
<solid
android:color="#4F4F4F"
/>
<padding
android:left="0dp"
android:top="0dp"
android:right="0dp"
android:bottom="0dp"
/>
<size
android:width="270dp"
android:height="60dp"
/>
</shape>
While I do not clearly understand what your requirements are exactly, I would like to point out one thing though.
For Applying a style to a SearchView we have to use the theme attribute, your code seems okay, maybe your changes are not being applied for now I believe. So try using the android:theme attribute for your style as follows. The rest of your requirements should easily come by to you with some trial and error I believe. Thanks.
<androidx.appcompat.widget.SearchView
android:id="#+id/searchView"
android:theme="#style/SearchViewStyle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="8dp"
android:layout_marginEnd="8dp"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toTopOf="parent">
Here is how I would recommend you to update your style to get as close as possible to your design.
<style name="SearchViewStyle" parent="Widget.AppCompat.SearchView">
<item name="searchIcon">#drawable/ic_baseline_dark_search_24</item>
<item name="queryBackground">#android:color/transparent</item>
<item name="queryHint">"search_hint"</item>
<item name="iconifiedByDefault">false</item>
<item name="android:textColorHint">#color/white</item>
<item name="android:background">#drawable/radius_drawable</item>
</style>
And you can modify your drawable and get rid of the padding and size since you are using wrap_content in your layout
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#4F4F4F" />
<corners android:radius="18dp" />
</shape>
You can use custom searchview in AppCompat SearchView . Copy searchview from this link searchview.xml
Then edit the xml or remove the extra margin from xml.
Add custom searchview layout like this:
<androidx.appcompat.widget.SearchView
android:id="#+id/search"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentEnd="true"
android:layout_centerVertical="true"
android:gravity="center"
app:layout="#layout/custom_search_view"
app:iconifiedByDefault="true"
app:queryBackground="#android:color/transparent"
app:queryHint="Search"
app:searchIcon="#drawable/search" />
I'm trying to create an outlined Material Components button, however I need it to have a semi-transparent background in addition to the stroke.
This is my XML code so far:
<android.support.design.button.MaterialButton
android:id="#+id/foo"
style="#style/Widget.MaterialComponents.Button.TextButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button"
app:backgroundTint="#CFFF"
app:strokeColor="#color/colorAccent"
app:strokeWidth="2dp" />
And this is what this looks like:
The issue is that some of the background is visible outside the stroke around the button (the larger the stroke width, the more white pixels getting out).
For example, here's a 5dp stroke:
Is there a way to fix this, a better way to set the background color, or anything?
Just use the Widget.MaterialComponents.Button.OutlinedButton style:
<com.google.android.material.button.MaterialButton
style="#style/Widget.MaterialComponents.Button.OutlinedButton"
app:strokeWidth="2dp"
app:strokeColor="#color/colorAccent"
app:backgroundTint="#3ad64f"
.../>
If you create a style of that you have to remove the app: In my example this style is called SecondButton
<style name="SecondButton" parent="Widget.MaterialComponents.Button.OutlinedButton">
<item name="android:theme">#style/SecondButtonTheme</item>
<item name="backgroundTint">#color/second_button_back</item>
<item name="strokeColor">#color/second_button_text</item>
<item name="strokeWidth">1dp</item>
<item name="android:textColor">#color/second_button_text</item>
</style>
Use it like that in you
<com.google.android.material.button.MaterialButton
style="#style/SecondButton"
.../>
You could try to create your button in drawables directly in xlm based on this :
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle">
<solid android:color="backgroundcolor"/>
<stroke android:color="strokecolor" android:width="2dp" />
<!--corners allow us to make the rounded corners button-->
<corners android:radius="15dp" />
</shape>
</item>
</selector>
founded here : https://android--code.blogspot.fr/2015/01/android-rounded-corners-button.html
and use it like this in your layout :
android:background="#drawable/nameofbutton.xml"
I know how to make Material Design button with color fill:
style="#style/Widget.AppCompat.Button.Colored"
And no-bordered transparent button:
style="#style/Widget.AppCompat.Button.Borderless.Colored"
However, is there a way to make Material design bordered (transparent inside) button? Something like below?
You can also use the Material Components for Android.
Add the dependency to your build.gradle:
dependencies { implementation 'com.google.android.material:material:1.3.0' }
In this case you can use the MaterialButton in your layout file:
<com.google.android.material.button.MaterialButton
....
style="#style/Widget.MaterialComponents.Button.OutlinedButton"
app:cornerRadius=".."
app:strokeColor="#color/colorPrimary"/>
Apply the style #style/Widget.MaterialComponents.Button.OutlinedButton.
In your case use the app:cornerRadius attribute to change the size of corner radius. This will round off the corners with specified dimensions.
Use te attribute app:strokeColor and app:strokeWidth to change the color and the width of the border.
You can also customize the corners using ShapeApperance (it requires version 1.1.0)
<style name="MyButton" parent="Widget.MaterialComponents.Button.OutlinedButton">
<item name="shapeAppearanceOverlay">#style/MyShapeAppearance</item>
</style>
<style name="MyShapeAppearance" parent="">
<item name="cornerFamilyTopLeft">rounded</item>
<item name="cornerFamilyBottomLeft">rounded</item>
<item name="cornerFamilyTopRight">cut</item>
<item name="cornerFamilyBottomRight">cut</item>
<item name="cornerSize">8dp</item>
</style>
The official doc is here and all the android specs here.
With jetpack compose you can use the OutlinedButton and the border attribute:
OutlinedButton(
onClick = { },
border = BorderStroke(1.dp, Color.Blue),
shape = RoundedCornerShape(8.dp)
) {
Text(text = "Save")
}
OLD (support library)
With the new Support Library 28.0.0, the Design Library now contains the Material Button.
You can add this button to our layout file with:
<android.support.design.button.MaterialButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="XXXX"
android:textSize="18sp"
app:icon="#drawable/ic_android_white_24dp" />
You can customize the button with these attributes:
app:backgroundTint: Used to apply a tint to the background of the button. If you wish to change the background color of the button, use this attribute instead of background.
app:strokeColor: The color to be used for the button stroke
app:strokeWidth: The width to be used for the button stroke
Also
Here's how to do it correctly.
What you need to do is
1 - Create shape drawable with stroke
2 - Create ripple drawable
3 - Create selector drawable for less than v21
4 - Create a new style for button with border
5 - Apply style on button
1 - Create shape with stroke
btn_outline.xml
<?xml version="1.0" encoding="utf-8"?>
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<stroke
android:width="2dp"
android:color="#color/colorAccent">
</stroke>
<solid android:color="#color/colorTransparent"/>
<corners
android:radius="5dp">
</corners>
</shape>
2 - Create ripple drawable
drawable-v21/bg_btn_outline.xml
<?xml version="1.0" encoding="utf-8"?>
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
android:color="#color/colorOverlay">
<item>
<shape>
<stroke
android:width="2dp"
android:color="#color/colorAccent"/>
<corners android:radius="5dp"/>
</shape>
</item>
<item android:id="#android:id/mask">
<shape>
<stroke
android:width="2dp"
android:color="#color/colorAccent"/>
<solid android:color="#android:color/white"/>
<corners android:radius="5dp"/>
</shape>
</item>
</ripple>
android:id="#android:id/mask" is required to have ripple touch feedback on the button. The layer that is marked as mask is not visible on screen, its just for touch feedback.
3 - Create selector drawable for less than v21
drawable/bg_btn_outline.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/btn_outline" android:state_pressed="true">
<shape android:shape="rectangle">
<solid android:color="#color/colorOverlay"/>
</shape>
</item>
<item android:drawable="#drawable/btn_outline" android:state_focused="true">
<shape android:shape="rectangle">
<solid android:color="#color/colorOverlay"/>
</shape>
</item>
<item android:drawable="#drawable/btn_outline"/>
</selector>
4 - Create a new style for button with border
All resources that that are needed to create the style are given above, that's how your style should look like
<style name="ButtonBorder" parent="Widget.AppCompat.Button.Colored"/>
<style name="ButtonBorder.Accent">
<item name="android:background">#drawable/bg_btn_outline</item>
<item name="android:textColor">#color/colorAccent</item>
<item name="android:textAllCaps">false</item>
<item name="android:textSize">16sp</item>
<item name="android:singleLine">true</item>
</style>
4 - Apply style on button
<Button
style="#style/ButtonBorder.Accent"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
That's pretty much it. Here's a sample of how the buttons looks now.
You could do this pretty easily by setting Material Design Button's style attribute to #style/Widget.MaterialComponents.Button.OutlinedButton and setting app:strokeColor attribute value to your preferred color.
example:
<com.google.android.material.button.MaterialButton
android:text="Rounded outlined button"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:id="#+id/btnRound"
style="#style/Widget.MaterialComponents.Button.OutlinedButton"
app:strokeColor="#color/colorPrimaryDark"/>

Credits to #NomanRafique for the detailed answer! However, because of the custom background, we've lost a few important things:
Button's height is bigger than the default Widget.AppCompat.Button
Paddings
Enable/Disable states
In case you're wondering, here is how the default background looks like: https://android.googlesource.com/platform/frameworks/support/+/a7487e7/v7/appcompat/res/drawable-v21/abc_btn_colored_material.xml
By reusing original insets, paddings and color selectors, in a simple case we can come up with something like this (all the values are default and come from android support/material library) :
drawable-v21/bg_btn_outlined.xml
<inset xmlns:android="http://schemas.android.com/apk/res/android"
android:insetLeft="#dimen/abc_button_inset_horizontal_material"
android:insetTop="#dimen/abc_button_inset_vertical_material"
android:insetRight="#dimen/abc_button_inset_horizontal_material"
android:insetBottom="#dimen/abc_button_inset_vertical_material">
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
android:color="?attr/colorControlHighlight">
<item>
<shape>
<stroke
android:width="2dp"
android:color="#color/abc_btn_colored_borderless_text_material"/>
<corners android:radius="#dimen/abc_control_corner_material"/>
<padding
android:bottom="#dimen/abc_button_padding_vertical_material"
android:left="#dimen/abc_button_padding_horizontal_material"
android:right="#dimen/abc_button_padding_horizontal_material"
android:top="#dimen/abc_button_padding_vertical_material"/>
</shape>
</item>
<item android:id="#android:id/mask">
<shape>
<stroke
android:width="2dp"
android:color="#color/abc_btn_colored_borderless_text_material"/>
<solid android:color="#android:color/white"/>
<corners android:radius="#dimen/abc_control_corner_material"/>
</shape>
</item>
</ripple>
</inset>
styles.xml
<style name="Button.Outlined" parent="Widget.AppCompat.Button.Borderless.Colored">
<item name="android:background">#drawable/bg_btn_outlined</item>
</style>
At this point, we should have an outlined button that responds to touches, respects the enabled="false" state and of the same height as the default Widget.AppCompat.Button:
Now, from here you can start customizing colors by providing your own implementation of the #color/abc_btn_colored_borderless_text_material color selector.
In your XML use this,
<com.google.android.material.button.MaterialButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Its a button"
android:textColor="#android:color/white"
android:textSize="#dimen/_12ssp"
app:backgroundTint="#android:color/transparent"
app:strokeColor="#android:color/white"
app:strokeWidth="#dimen/_1sdp" />
where
app:backgroundTint is used for background color
app:strokeColor is border color
app:strokeWidth is border width
This is how I do buttons only with a border and the ripple effect on Lollipop and above. Just like the AppCompat buttons, these have a fallback pressed effect on lower APIs (if you need ripples on lower APIs, you need to use an external library). I use FrameLayout because it's cheap. The color of the text and the border is black, but you can change it with a custom one:
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="20dp"
android:background="#drawable/background_button_ghost">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?android:selectableItemBackground"
android:gravity="center"
android:padding="14dp"
android:textSize="16sp"
android:textAllCaps="true"
android:textStyle="bold"
android:textColor="#android:color/black"
android:text="Text"/>
</FrameLayout>
drawable/background_button_ghost.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<stroke
android:width="2dp"
android:color="#android:color/black"/>
<solid android:color="#color/transparent"/>
</shape>
If I have missed something, please leave a comment and I will update the answer.
You can do this with Jetpack Compose too. To do it, just create a composable function with a OutlinedButton and pass the as parameter the border you want:
#Composable
fun OutlineButton() {
OutlinedButton(
onClick = { //TODO - implement click here },
border = BorderStroke(1.dp, Color.Blue), // <-- border property
shape = RoundedCornerShape(corner = CornerSize(20.dp)),
colors = ButtonDefaults.outlinedButtonColors(contentColor = Color.Blue)
){
Text(text = "CONFIRM")
}
}
Just use MaterialButton with an outline style.
<com.google.android.material.button.MaterialButton
...
style="#style/Widget.MaterialComponents.Button.OutlinedButton"
android:text="Delete Mentor Manager"
app:strokeColor="#color/...."
app:strokeWidth="1dp" />
Simply you can use this code. Its looks soo Good.
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#ffffff"
android:orientation="vertical">
<android.support.v7.widget.AppCompatButton
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:backgroundTint="#F48025"
android:text="login"
android:textColor="#color/colorWhite" />
</LinearLayout>
Here border color is:
android:background="#ffffff"
And background color is:
android:backgroundTint="#F48025"
<Button
android:id="#+id/btn_add_discussion"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginHorizontal="15dp"
android:padding="8dp"
android:layout_marginTop="10dp"
android:layout_marginBottom="5dp"
android:backgroundTint="#80ffffff"
android:textColor="#color/colorPrimaryDark"
style="#style/btn_start_new_discussion"
android:text="Start new discussion" />
Put below code in Styles.xml file :
<style name="btn_start_new_discussion">
<item name="android:layout_marginTop">15dp</item>
<item name="strokeWidth">2dp</item>
<item name="strokeColor">#color/colorPrimary</item>
<item name="cornerRadius">10dp</item>
</style>
I have come across this weird issue in which the EditText fields change color to Red in the start of an Activity like they change incase there is a SetError. Also, this does not happen everytime, only in some cases it appears. How do I fix this bug? Any help is appreciated.
Please refer image for more.
here is the code
<android.support.design.widget.TextInputLayout
android:id="#+id/input_name"
style="#style/my_style_textInput"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="8dp">
<EditText
android:id="#+id/edt_name"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Name:"
android:inputType="textPersonName"
android:singleLine="true"
android:textSize="#dimen/subHeading" />
</android.support.design.widget.TextInputLayout>
Here is the style:
<style name="my_style_textInput" parent="#style/TextAppearance.AppCompat">
//hint color And Label Color in False State
<!--<item name="android:textColorHint">#color/item_color</item>-->
<!--<item name="android:textColor">#color/colorPrimary</item>-->
<item name="android:textSize">#dimen/caption</item>
//Label color in True State And Bar Color False And True State
<item name="colorAccent">#color/colorPrimary</item>
<item name="colorControlNormal">#color/colorPrimary</item>
<item name="colorControlActivated">#color/colorPrimaryAccent</item>
</style>
Please note, none of colorPrimary, colorAccent and item_color are red.Thank You.
You can use this code to customize the color.
Apply android:background="#drawable/edittext_bg" on your layout
<EditText
android:la`enter code here`yout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/login_username"
android:hint="#string/username_hint"
/>
After under drawable and create the file edittext_bg.xml and put this code inside.
<layer-list>
<item>
<shape android:shape="rectangle">
<!-- Draw a 2dp width border around shape -->
<stroke android:color="#ff1e0c" android:width="2dp"/>
</shape>
</item>
<!-- Overlap the left, top and right border using background color -->
<item android:bottom="2dp">
<shape android:shape="rectangle">
<solid android:color="#fffbce"/>
</shape>
</item>
Hope it helps you.
I am using a appcompat theme for my application. Need to know how i can show underline to spinner. It is just showing anchor. I tried setting up underline using android:background but it makes the anchor disappear.
Update your support library and in XML use
Please add this style to your Spinner
style="#style/Base.Widget.AppCompat.Spinner.Underlined"
This is hacky (and not perfect) way to change spinner and underline color in appcompat theme. Main point that I customized Android support library images and xml files to change color.
1) go to support library package and copy 2 images (or download my custom from the bottom of this post)
/your-app/build/intermediates/exploded-aar/com.android.support/appcompat-v7/23.1.0/res/drawable-hdpi/abc_spinner_mtrl_am_alpha.9.png
and
/your-app/build/intermediates/exploded-aar/com.android.support/appcompat-v7/23.1.0/res/drawable-hdpi/abc_textfield_default_mtrl_alpha.9.png
2) Make a copy of those images
3) Change color of abc_spinner_mtrl_am_alpha.9.png (warning: leave black borders as they are, it's for 9 patch)
4) Change color of second bottom line of abc_textfield_default_mtrl_alpha.9.png (you can see in attached small image below)
5) Save and move files to your project drawables
6) Create bottom_line_color.xml drawable:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:top="-6dp" android:left="-6dp" android:right="-6dp">
<shape>
<stroke android:color="#color/brown" android:width="6dp"/>
</shape>
</item>
7) Create spinner_bottom_line.xml
<?xml version="1.0" encoding="utf-8"?>
<inset xmlns:android="http://schemas.android.com/apk/res/android"
android:insetLeft="#dimen/abc_control_inset_material"
android:insetTop="#dimen/abc_control_inset_material"
android:insetBottom="#dimen/abc_control_inset_material"
android:insetRight="#dimen/abc_control_inset_material">
<selector>
<item android:state_checked="false" android:state_pressed="false">
<layer-list>
<item android:drawable="#drawable/my_custom_abc_textfield_default_mtrl_alpha" />
<item android:drawable="#drawable/my_custom_abc_spinner_mtrl_am_alpha" />
</layer-list>
</item>
<item>
<layer-list>
<item android:drawable="#drawable/my_custom_abc_textfield_default_mtrl_alpha" />
<item android:drawable="#drawable/my_custom_abc_spinner_mtrl_am_alpha" />
</layer-list>
</item>
</selector>
</inset>
P.S. I couldn't achieve same visual style as default spinner (visual changes shown below). If you start using this custom spinner theme you should use it in all project.
So add to values/styles.xml
<style name="My.Spinner.Style" parent="Base.Widget.AppCompat.Spinner.Underlined">
<item name="android:background">#drawable/spinner_bottom_line</item>
</style>
And use it in application like this:
<Spinner
android:id="#+id/account_spinner"
android:layout_width="match_parent"
android:layout_height="wrap_content"
style="#style/My.Spinner.Style"
/>
Important:
You should resize spinner and place to various drawables folders. You can find size in same path as I showed above.
There are few popular sizes:
drawables-mdpi 20x26
drawables-hdpi 29x38
drawables-xhdpi 38x50
drawables-xxhdpi 74x98
You can take my customized images from here:
my_custom_abc_spinner_mtrl_am_alpha:
my_custom_abc_textfield_default_mtrl_alpha:
Spinner example is (xxhdpi), line is mdpi (because we don't need various lines in various drawable folders, so we can have only 1).
Visual difference (from android studio xml preview window) is shown here:
First line is my custom underline spinner, second is default Base.Widget.AppCompat.Spinner.Underlined
Applying style="#style/Base.Widget.AppCompat.Spinner.Underlined" didn't show any difference .Then gave android:backgroundTint and android:backgroundTintMode to spinner and it worked.
<Spinner
android:id="#+id/spBookingType"
android:spinnerMode="dropdown"
android:layout_marginLeft="16dp"
android:layout_marginRight="16dp"
android:layout_width="match_parent"
android:layout_height="wrap_content"
style="#style/Base.Widget.AppCompat.Spinner.Underlined"
android:backgroundTint="#ff000000"
