Shadow property in Button view gives shadow to text. How can I give shadow to right and bottom border of a Button?As shown below:
You can try it. I use it in my project. I give shadow to right and bottom border of a Button.
Button xml
<Button
android:id="#+id/buttonSignIn"
android:layout_width="fill_parent"
android:layout_height="50dp"
android:background="#drawable/button_dropshadow"
android:textColor="000000"
android:text="Sign In" />
In drawable file add button_dropshadow.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<layer-list>
<item android:left="5dp" android:top="5dp">
<shape>
<corners android:radius="3dp" />
<solid android:color="#000000" />
</shape>
</item>
<item android:bottom="2dp" android:right="2dp">
<shape>
<gradient android:angle="270"
android:endColor="#ffffff" android:startColor="#ffffff" />
<stroke android:width="1dp" android:color="#000000" />
<corners android:radius="4dp" />
<padding android:bottom="10dp" android:left="10dp"
android:right="10dp" android:top="10dp" />
</shape>
</item>
</layer-list>
</item>
</selector>
Thank you.
Try making your own button 9-patch image with selector:
btn_normal.9.png:
btn_pressed.9.png:
btn_focused.9.png:
btn_selector.xml:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_selected="true" android:drawable="#drawable/btn_focused" />
<item android:state_focused="true" android:drawable="#drawable/btn_focused" />
<item android:state_pressed="true" android:drawable="#drawable/btn_pressed" />
<item android:drawable="#drawable/btn_normal" />
</selector>
and add android:background="#drawable/btn_selector" in button's attributes.
Here is a blob post that I found and could help. It will only work in a RelativeLayout. Create a View component with the same size as your button and place it immediately below:
<Button
android:id="+#id\my_button"
android:layout_below="#id/some_layout_item"
android:layout_width="100dp"
android:layout_height="5dp"
>
</Button>
<View
android:layout_below="#id/my_button"
android:layout_width="100dp"
android:layout_height="5dp"
android:background="#drawable/drop_shadow"
>
</View>
Create the shadow as a drawable (drop_shadow.xml):
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android=”http://schemas.android.com/apk/res/android”>
<gradient
android:startColor="#color/cream_dark"
android:endColor="#color/cream"
android:angle="270"
>
</gradient>
</shape>
My button's background is set like this
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
<gradient
android:startColor="#android:color/holo_green_dark"
android:endColor="#android:color/holo_green_light"
android:angle="90">
</gradient>
<stroke
android:width="1px"
android:color="#android:color/darker_gray" />
</shape>
The effect of the shadow can be done by adding a second shape under the original button shape, changing its color to a darker one either black or grey. But the shadow should be of the same shape as that of the button.
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
<solid android:color="#android:color/darker_gray"/>
</shape>
To overlap different items we have to use a “layer-list” resource and include the previous shapes. The shadow should appear in first place and then the original button with some displacement. In this example, we are creating the shadow at the bottom of the button and an offset of 4px.
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:drawable="#drawable/shadow"/>
<item
android:drawable="#drawable/button"
android:bottom="4px"
android:right="4px"
/>
</layer-list>
Now set the background of the button as the layerlist drawable. This should do it partially.

I need to create a custom image view for choosing color by design. When user click the circle, inner white circle with a tick should appear, like in example below:
Otherwise, it should be just a circle shape with some color (unchecked state), like below:
The main problem, that I do not know how to create a selector with the inner circle inside and with keeping the ability to setup color programmatically.
Simple rounded shape I can setup, for example, like this:
<de.hdodenhof.circleimageview.CircleImageView
android:id="#+id/circle_crop"
android:layout_width="32dp"
android:layout_height="32dp"
android:layout_gravity="center"
android:src="#android:color/holo_red_dark" />
How to modify it to setup white circle with tick inside on a checked state (when user click on it)?
So easy.
1. Create layer-list Drawable Called "icon_check"
<layer-list
xmlns:android="http://schemas.android.com/apk/res/android">
<item //for the round white background
android:bottom="10dp" //margin, "<size>" tag doesn't work
android:end="10dp"
android:start="10dp"
android:top="10dp">
<shape
android:shape="oval">
<solid
android:color="#color/white" />
</shape>
</item>
<item
android:drawable="#drawable/check" //check mark from built-in asset
android:bottom="14dp" //margin, extra 4dp is prefered
android:end="14dp"
android:start="14dp"
android:top="14dp" />
</layer-list>
2. Create selector Drawable Called "foreground_check"
<selector
xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:drawable="#drawable/icon_check" //layer-list created above
android:state_selected="true" />
<item
android:drawable="#android:color/transparent" //key point, 【"#null" doesn't work!!】
android:state_selected="false" />
</selector>
3. Setup CardView
<androidx.cardview.widget.CardView //【MaterialCardView doesn't work!!】
android:id="#+id/cardView"
android:layout_width="40dp"
android:layout_height="40dp"
android:foreground="#drawable/foreground_check" //apply layer-list drawable
app:cardBackgroundColor="#color/black"
app:cardCornerRadius="20dp" /> //half of side length
4. Setup Ui Controller
cardView.setOnClickListener {
it.isSelected = !it.isSelected
}
Result:
You need to create a drawable selector for your image view, for example:
drawable_round_view_selector
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/drawable_round_view_selected" android:state_selected="true" />
<item android:drawable="#drawable/drawable_round_view_unselected" android:state_selected="false" />
<item android:drawable="#drawable/drawable_round_view_unselected" />
</selector>
drawable_round_view_selected
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="oval">
<size
android:width="40dp"
android:height="40dp" />
<padding
android:bottom="10dp"
android:left="10dp"
android:right="10dp"
android:top="10dp" />
<stroke
android:width="1dp"
android:color="#3383FF" />
<solid android:color="#3383FF"/>
</shape>
</item>
<item>
<shape android:shape="oval">
<size
android:width="40dp"
android:height="40dp" />
<solid android:color="#ffffff" />
</shape>
</item>
<item android:drawable="#drawable/ic_baseline_check_24" />
</layer-list>
and drawable_round_view_unselected
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<size
android:width="40dp"
android:height="40dp" />
<!-- unselected button background -->
<solid
android:color="#color/black" />
<stroke
android:color="#color/gray_martini"
android:width="1dp"/>
</shape>
After that on your layout set the image view like:
<ImageView
android:id="#+id/roundImageView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintBottom_toBottomOf="parent"
android:src="#drawable/drawable_round_view_selector"/>
Finally on your activity or fragment change view depending on selected state:
binding.roundImageView.setOnClickListener {
it.isSelected = !it.isSelected
}
PS: change colors and sizes depending on your requirements.
i'm trying to create a border for a Button with two color white and black. So I decide to create a shape. i trying to add gradient with white and black color my code doesn't work
i want border like this :

stroke_width_inner should be twice of stroke_width_outer always
Apply background to button -
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/button_background"
android:text="OK"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent" />
On Layout Editor -
On Device -
On Device you won't see the grayish left and top border as you see on Layout Editor
This appears to be a good place to use a 9-patch image. Any solution based on a regular .png file, a <shape>, or a <vector> will wind up scaling the white and black borders of your button.
Once you've created your button.9.png file, then you can set it to be your button's background using android:background="#drawable/button".
Edit
Here's a 9-patch based on your linked .png file:
Please look here about creating a shape drawable http://developer.android.com/guide/topics/resources/drawable-resource.html#Shape
Once you have done this, in the XML for your button set android:background="#drawable/your_button_border"
I made a rounded button with xml drawable and applied android:foreground="?attr/selectableItemBackground" in hope of getting a ripple effect. However, ripple effect does not work. Is there anyway to make the ripple effect work? As a workaround I wrapped the button with a FrameLayout and applied android:foreground="?attr/selectableItemBackground" to it, but in that case the ripple is rectangular and goes beyond button (as it is rounded).
xml:
<Button
android:id="#+id/reg_next"
android:layout_width="125dp"
android:layout_height="40dp"
android:text="#string/next"
android:layout_gravity="center"
android:textAllCaps="false"
android:textColor="#color/colorPrimary"
android:textSize="18sp"
android:background="#drawable/rounded_button_background"
android:foreground="?attr/selectableItemBackground"/>
rounded_button_background:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" android:padding="10dp">
<solid android:color="#ebeff1"/> <!-- this one is ths color of the Rounded Button -->
<stroke android:width="1px" android:color="#979797" />
<corners
android:radius="20dp"
android:bottomLeftRadius="20dp"
android:topLeftRadius="20dp"
android:topRightRadius="20dp"/>
</shape>
You need to create ripple drawable and set it as button background (without foreground attribute):
rounded_button_background.xml
<?xml version="1.0" encoding="utf-8"?>
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
android:color="#2793c9">
<item>
<shape
android:padding="10dp"
android:shape="rectangle">
<solid android:color="#ebeff1" /> <!-- this one is ths color of the Rounded Button -->
<stroke
android:width="1px"
android:color="#979797" />
<corners
android:bottomLeftRadius="20dp"
android:radius="20dp"
android:topLeftRadius="20dp"
android:topRightRadius="20dp" />
</shape>
</item>
</ripple>
If you want support api bellow 21 (without ripple effect), add this drawable to directory drawable-v21 and in directory drawable create these files:
rounded_btn_normal.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:padding="10dp"
android:shape="rectangle">
<solid android:color="#ebeff1" /> <!-- this one is ths color of the Rounded Button -->
<stroke
android:width="1px"
android:color="#979797" />
<corners
android:bottomLeftRadius="20dp"
android:radius="20dp"
android:topLeftRadius="20dp"
android:topRightRadius="20dp" />
</shape>
rounded_btn_active.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:padding="10dp"
android:shape="rectangle">
<solid android:color="#2793c9" /> <!-- this one is ths color of the Rounded Button -->
<stroke
android:width="1px"
android:color="#979797" />
<corners
android:bottomLeftRadius="20dp"
android:radius="20dp"
android:topLeftRadius="20dp"
android:topRightRadius="20dp" />
</shape>
rounded_button_background.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/rounded_btn_active" android:state_enabled="true" android:state_pressed="true" />
<item android:drawable="#drawable/rounded_btn_normal" android:state_enabled="true" />
</selector>
I have a customized button with rounded corners, I put some shadow for when it's pressed but I want to do an outer shadow just to the bottom part of the button, I am making the drawable via xml, so if the glow could be that way would be great.
These are the relevant parts of the code:
button_pressed_shadows.xml
<?xml version="1.0" encoding="UTF-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item>
<shape android:shape="rectangle" >
<gradient
android:startColor="#color/black_overlay"
android:endColor="#color/btn_login"
android:angle="270"/>
<corners android:radius="4dip" />
</shape>
</item>
<item
android:top="2px">
<shape android:shape="rectangle">
<solid android:color="#color/btn_login"/>
<corners android:radius="4dip" />
</shape>
</item>
</layer-list>
style_login.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true"
android:drawable="#drawable/button_pressed_shadows" /> <!-- pressed -->
<item android:state_focused="true"
android:drawable="#drawable/button_focused" /> <!-- focused -->
<item android:state_hovered="true"
android:drawable="#drawable/button_focused" /> <!-- hovered -->
<item android:drawable="#drawable/button_login" /> <!-- default -->
</selector>
Since I have the button design on photoshop, I made a 9 patch image with it, and put it on the style selector, everything went fine, think is the better (easiest) way.
Also while using layer-list you can use appropriate color combinations and padding to make it like glow or shadow.
edit_text_background
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item>
<shape android:shape="rectangle" >
<solid android:color="#fff" />
<corners android:radius="4dp" />
</shape>
</item>
<item android:bottom="1dp">
<shape android:shape="rectangle" >
<corners android:radius="4dp" />
<stroke
android:width="1dp"
android:color="#dadad7" />
<solid android:color="#fff" />
</shape>
</item>
I have some buttons which I set its background color as red, green and blue separately. When I press the button, click event is generated, but there is no change in gui for the user to know the button is pressed. Android button’s default background grayish color changes to orange and come back to grayish color after releasing the pressed state. How to implement this on colored button?
That is implemented via a StateListDrawable, represented by selector in XML. Reference: http://developer.android.com/guide/topics/resources/drawable-resource.html#StateList
Here is an example of a drawable that will be white by default, black when pressed:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true"
android:drawable="#android:color/black" /> <!-- pressed -->
<item android:drawable="#android:color/white" /> <!-- default -->
</selector>
As mentioned by K-Ballo you can use StateListDrawable to implement a view with various different graphics depending on state. In your case Button is the view where two states are Button pressed and button not pressed.
We need to create a buttonselector.xml file in the drawable folder
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/button_not_pressed" android:state_pressed="false" android:state_selected="false"/>
<item android:drawable="#drawable/button_pressed" android:state_pressed="true"/>
</selector>
Create two separate xml files for the state of the button
button_not_pressed.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient
android:startColor="#FFFFFF"
android:centerColor="#FFFFFF"
android:endColor="#FFFFFF"
android:angle="270" />
</shape>
button_pressed.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient
android:startColor="#FF0000"
android:centerColor="#FF0000"
android:endColor="#FF0000"
android:angle="270" />
</shape>
You will notice two html color codes #FF0000 & #FFFFFF which represent background color of the button according to the state.
In you main.xml where you set the style of your custom button
<Button
android:id="#+id/customButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/buttonselector"
android:text="test"
android:textColor="#000000" />
In you activity class add the following two lines
Button customButton = (Button) findViewById(R.id.customButton);
customButton.setBackground(getResources().getDrawable(R.drawable.buttonselector));
Hope it helps
Try out this way:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:state_pressed="true" >

<solid
android:color="#1E669B" />

android:color="#1B5E91" />
<corners
android:radius="6dp" />
<padding
android:left="10dp"
android:top="10dp"
android:right="10dp"
android:bottom="10dp" />
</shape>
</item>
<item>
<shape>
