Button is not filling parent container height [duplicate]

Currently, I have the following bottom log in button.
When button is not being pressed
When button is being pressed
The XML looks like this
<LinearLayout
android:background="?attr/welcomeBottomNavBarBackground"
android:orientation="horizontal"
android:id="#+id/sign_in_bottom_nav_bar"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true">
<Button
style="?android:attr/buttonBarButtonStyle"
android:id="#+id/sign_in_button"
android:layout_width="0dp"
android:width="0dp"
android:layout_weight="1.0"
android:layout_height="48dp"
android:gravity="center"
android:layout_gravity="center"
android:enabled="true"
android:textAllCaps="true"
android:text="#string/log_in" />
</LinearLayout>
I would like to remove the padding (Or should I call it margin? Please refer to my bottom most p/s section) around button when it is being pressed.
I look at How to remove padding around buttons in Android?
I had tried
<Button
...
...
android:minHeight="0dp"
android:minWidth="0dp" />
It doesn't work and has no effect.
I further try
<Button
...
...
android:background="#null"
android:minHeight="0dp"
android:minWidth="0dp" />
No more padding when pressed. However, the material designed pressed visual effect will gone too.
May I know what is the best way to remove button padding during pressed, yet retain the material designed pressed visual effect?
P/S
I don't really know whether I should call it padding or margin. What I wish to achieve is that, when we press on the bottom region, press visual effect change should be covered entire 100% bottom bar region (#+id/sign_in_bottom_nav_bar), instead of current 95% bottom bar region.

A standard button is not supposed to be used at full width which is why you experience this.
Background
If you have a look at the Material Design - Button Style you will see that a button has a 48dp height click area, but will be displayed as 36dp of height for...some reason.
This is the background outline you see, which will not cover the whole area of the button itself.
It has rounded corners and some padding and is supposed to be clickable by itself, wrap its content, and not span the whole width at the bottom of your screen.
Solution
As mentioned above, what you want is a different background. Not a standard button, but a background for a selectable item with this nice ripple effect.
For this use case there is the ?selectableItemBackground theme attribute which you can use for your backgrounds (especially in lists).
It will add a platform standard ripple (or some color state list on < 21) and will use your current theme colors.
For your usecase you might just use the following:
<Button
android:id="#+id/sign_in_button"
style="?android:attr/buttonBarButtonStyle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Login"
android:background="?attr/selectableItemBackground" />
<!-- /\ that's all -->
There is also no need to add layout weights if your view is the only one and spans the whole screen
If you have some different idea on what your background should look like you have to create a custom drawable yourself, and manage color and state there.

As simple, use the inset property like:
android:insetTop="0dp"
android:insetBottom="0dp"
android:insetRight="0dp"
android:insetLeft="0dp"

In styles.xml
<style name="MyButtonStyle" parent="Base.Widget.AppCompat.Button">
<item name="android:background">#drawable/selector</item>
<item name="android:textColor">#android:color/black</item>
</style>
In values/drawable:
my_drawable.xml
<?xml version="1.0" encoding="utf-8"?>
<shape android:shape="rectangle" xmlns:android="http://schemas.android.com/apk/res/android">
<corners android:radius="2dp" />
<!-- specify your desired color here -->
<solid android:color="#9e9b99" />
</shape>
selector.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_focused="true" android:drawable="#drawable/my_drawable"/>
<item android:state_pressed="true" android:drawable="#drawable/my_drawable"/>
<item android:drawable="#android:color/transparent"/>
</selector>
In values/drawable-v21:
my_drawable.xml
<?xml version="1.0" encoding="utf-8"?>
<shape android:shape="rectangle"
android:tint="?attr/colorButtonNormal"
xmlns:android="http://schemas.android.com/apk/res/android">
<corners android:radius="2dp" />
<solid android:color="#android:color/white" />
</shape>
selector.xml
<?xml version="1.0" encoding="utf-8"?>
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
android:color="?attr/colorControlHighlight">
<item android:id="#android:id/mask"
android:drawable="#drawable/my_drawable" />
</ripple>
In layout:
<Button
android:id="#+id/button"
style="#style/MyButtonStyle"
android:layout_width="match_parent"
android:layout_height="100dp"
android:text="Test"/>

I think the best solution to solve that is create your own Ripple Effect. The padding when you press the button is respecting the default Ripple Effect of the component.
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
android:color="?attr/colorControlHighlight">
<item android:drawable="?attr/colorPrimary"/>
</ripple>
Or you can try change the style of your button to style="?android:textAppearanceSmall"
Remember: This effect is only shown on Android Lollipop (API 21) or higher.

I have been through what you are going through. Long story short, you just cannot do it cleanly with a <Button> tag alone, while ensuring backwards compatibility.
The simplest and the most widely practiced method is to use a <RelativeLayout> underlay, around a <Button>.
Button Code:
<RelativeLayout
android:id="#+id/myButtonUnderlay"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/colorPrimary"
android:visibility="visible">
<Button
android:id="#+id/myButton"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/selectableItemBackgroundBorderless"
android:text="I am as cute as a Button"/>
</RelativeLayout>
Wherever you need to use a button, you use this complete code.
Here is the breakdown:
OnClick events will be hooked to myButton.
Control dimensions of your button, by changing attributes of myButtonUnderlay.
In myButton, android:background="?attr/selectableItemBackgroundBorderless". This will make it a transparent button with just the text, and backwards compatible ripples.
In myButtonUnderlay, you will do all the other background applications, like setting the color of the button, margins, paddings, borders, gradients, and shadows etc.
If manipulation of the button's visibility (programmatic or not) is wish, you do it on myButtonUnderlay.
Note: To ensure backwards compatibility, make sure that you use
android:background="?attr/selectableItemBackgroundBorderless", and NOT
android:background="?android:attr/selectableItemBackgroundBorderless"

As #David Medenjak answer you can read the Google Material design Button-style to its developer site. Use button style as #David Medenjak explained in his answer. You can also do by the following way also
It is not a padding or margin but it is actually background effect of button.
If you want to remove that then you can do as following.
Option 1:
Step 1: Put the below code in styles.xml
<style name="myColoredButton">
<item name="android:textColor">#FF3E96</item>
<item name="android:padding">0dp</item>
<item name="android:minWidth">88dp</item>
<item name="android:minHeight">36dp</item>
<item name="android:elevation">1dp</item>
<item name="android:translationZ">1dp</item>
<item name="android:background">#FF0000</item>
</style>
Step 2:Create a new XML file under drawables folder and add the following code: I named my XML file as button_prime.xml
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
android:color="#color/colorPrimary">
<item>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<corners android:radius="1dp" />
<solid android:color="#8B8386" />
</shape>
</item>
</ripple>
Step 3: Use the style and drawable in your Button as follows.
<Button
style="#style/myColoredButton"
android:layout_width="250dp"
android:layout_height="50dp"
android:text="Cancel"
android:gravity="center"
android:background="#drawable/button_prime"
android:colorButtonNormal="#3578A9" />
Option 2:
With the Support Library v7, all the styles are actually already defined and ready to use, for the standard buttons, all of these styles are available.So you can set your button style like this
<Button
style="#style/Widget.AppCompat.Button.Borderless"
android:layout_width="match_parent"
android:layout_height="50dp"
android:text="BUTTON"
android:gravity="center"
android:minHeight="0dp"
android:minWidth="0dp"
android:background="#color/colorAccent"/>
For more detail of Button style please check this answer
I think you will check this answer also. I hope you will get your solution.

The padding and margin may be a result of the original resources used in the button.
So you could try to change the resources used, using a selector:
<selector
xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:drawable="#drawable/btn_action_hover" />
<item android:state_selected="true" android:drawable="#drawable/btn_action_hover" />
<item android:state_focused="true" android:drawable="#drawable/btn_action_hover" />
<item android:drawable="#drawable/btn_action_normal" />
</selector>
That would change the default images/shapes for your buttons, so you could try using drawables and set every item to a drawable. The drawable being either a bitmap, or a .xml file(style file) defining the look of the button in its current state. I assume there still are some native styles included even though you have set the button-style yourself. This may be because you aren't using a custom theme. So the issue may also be solved by defing
theme="#style/myNewTheme"
where myNewTheme is your theme, and it should have any parents(parent="" should not be defined).
Take any given theme(designed by Google/Android, for an instance Theme.AppCompat.[name]), it does also come with a buttonStyle. This is a part of Theme.Holo.Light:
<!-- Button styles -->
<item name="buttonStyle">#style/Widget.Holo.Light.Button</item>
<item name="buttonStyleSmall">#style/Widget.Holo.Light.Button.Small</item>
<item name="buttonStyleInset">#style/Widget.Holo.Light.Button.Inset</item>
<item name="buttonStyleToggle">#style/Widget.Holo.Light.Button.Toggle</item>
<item name="switchStyle">#style/Widget.Holo.Light.CompoundButton.Switch</item>
<item name="mediaRouteButtonStyle">#style/Widget.Holo.Light.MediaRouteButton</item>
<item name="selectableItemBackground">#drawable/item_background_holo_light</item>
<item name="selectableItemBackgroundBorderless">?attr/selectableItemBackground</item>
<item name="borderlessButtonStyle">#style/Widget.Holo.Light.Button.Borderless</item>
<item name="homeAsUpIndicator">#drawable/ic_ab_back_holo_light</item>
As you see, this theme defines how your buttons will look/work in basic features. You can override parts of it, but you haven't overridden the important parts(being buttonStyle and similar). So if you create a new theme yourself and style it to your liking and set the theme(using theme="themename") and that theme does not inherit any theme, you should be able to style your buttons to your liking without having to worry about the default styles in the theme
Basically:
calling padding/margin="0dp" will not help. The default drawable defined by the theme has this in the button drawable, meaning you cannot change it. So you have to either change the button style, or change the theme completely. Make sure that theme does not have any parents, because many themes define the button style. You do not want the button style defined by the theme.

The best solution these days is just to use MaterialButton in place of Button.
Note: MaterialButton is visually different from Button and AppCompatButton. One of the main differences is that AppCompatButton has a 4dp inset on the left and right sides, whereas MaterialButton does not. To add an inset to match AppCompatButton, set android:insetLeft and android:insetRight on the button to 4dp, or change the spacing on the button’s parent layout.
When replacing buttons in your app with MaterialButton, you should inspect these changes for sizing and spacing differences.

I'd suggest you taking a look at this just in case before all.
Then, if not working i'd suggest you to create your own style (like azizbekian suggest)using android xml drawables, and drawable states to differentiate pressed/notpressed.
I think using your own style may be the best answer as it will further give you more control on how your app is displaying, but using android default themes and styles also allows the user to have custom styles which is a good idea. However, you cannot test every custom style so you cannot check that your app will display correctly on ALL custom styles, and therefore may encounter problems with some.

Set the Button background as android:background="?selectableItemBackground"
<LinearLayout
android:background="?attr/welcomeBottomNavBarBackground"
android:orientation="horizontal"
android:id="#+id/sign_in_bottom_nav_bar"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true">
<Button
style="?android:attr/buttonBarButtonStyle"
android:background="?selectableItemBackground"
android:id="#+id/sign_in_button"
android:layout_width="0dp"
android:width="0dp"
android:layout_weight="1.0"
android:layout_height="48dp"
android:gravity="center"
android:layout_gravity="center"
android:enabled="true"
android:textAllCaps="true"
android:text="#string/log_in" />
</LinearLayout>

After trying lots of solution, Finally I came to a conclusion that with tag alone we can't achieve this. to remove this unwanted space around button my solution is as below:
<RelativeLayout
android:id="#+id/myButtonUnderlay"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:visibility="visible">
<Button
android:id="#+id/save_button"
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_marginTop="-5dp"
android:layout_marginBottom="-5dp"
android:layout_above="#+id/content_scrollview"
android:layout_gravity="bottom"
android:background="#drawable/ripple_theme"
android:enabled="true"
android:text="SetUp Store"
android:textColor="#fff"
android:textSize="18sp"
android:visibility="gone"
tools:visibility="visible"
style="#style/MediumFontTextView" />
</RelativeLayout>

1.add a drawable resource file named maybe button_background.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true">
<shape>
<solid android:color="#ff0000"/>
<stroke android:width="5dp" android:color="#00ff00"/>
</shape>
</item>
<item>
<shape>
<solid android:color="#00ff00"/>
</shape>
</item>
</selector>
2.Use the button_background.xml as the button background, done!

I don't really know whether I should call it padding or margin.
The button is enacting surface elevation for providing visual feedback in response to touch. It is one of two feedbacks used for surface reaction; the first one being the ripple effect. For example, a raised button has resting state elevation of 2dp and pressed state elevation of 8dp (See raised button under Shadows). The button meets the finger as it touches the surface.
May I know what is the best way to remove button padding during pressed, yet retain the material designed pressed visual effect?
Having answered the first part, I do not believe you are having all of the material design if you wish to remove the surface elevation effect.
Anyways, here is how to remove surface elevation visual feedback:
Add animator file button_raise.xml to animator directory under res directory having the following code:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_enabled="true"
android:state_pressed="true">
<objectAnimator
android:duration="#android:integer/config_shortAnimTime"
android:propertyName="translationZ"
android:valueTo="0dp"
android:valueType="floatType" />
</item>
</selector>
Refer newly created animator in the button using stateListAnimator property:
<Button
...
android:stateListAnimator="#animator/button_raise"
... />
Hope this helps.

Background drawable not applying to button

I am trying to create a capsule/pill shaped button in XML. I have defined a drawable and set it as the background of my button, but in the preview, and when I run the app, it's displaying as a blue rectangle, despite the background drawable being a white oval. Does anyone know why that might be happening?
Here's the button:
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/search_box"
android:layout_centerHorizontal="true"
android:layout_marginTop="24dp"
android:background="#drawable/button_capsule"
android:text="#string/search"
android:textColor="#color/precipLightBlue"/>
And here's the background drawable:
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<corners android:radius="1000dp" />
<solid android:color="#android:color/white" />
</shape>

To have a capsule/pill shaped button you can use the MaterialButton in the official Material Component library using the app:cornerRadius attribute.
<com.google.android.material.button.MaterialButton
android:layout_width="100dp"
app:cornerRadius="32dp"
..../>
With the version 1.1.0 you can also customize the shape of your component using the app:shapeAppearanceOverlay attribute
<com.google.android.material.button.MaterialButton
....
app:shapeAppearanceOverlay="#style/ShapeAppearanceOverlay.ButtonRounded"
.../>
In the style define:
<style name="ShapeAppearanceOverlay.ButtonRounded" parent="">
<item name="cornerFamily">rounded</item>
<item name="cornerSize">32dp</item>
</style>
You can also try to use the ExtendedFloatingActionButton:
<com.google.android.material.floatingactionbutton.ExtendedFloatingActionButton
android:id="#+id/exfab"
android:layout_width="wrap_content"
.... />

You put a shape that you didn't defined. To define an oval you should put the shape="oval" option in the tag. Although i think you want a rectangle with rounded corners as i see in your code.
Also 1000dp radius is a lot, maybe that's making an issue.
Define size too. Because that shape doesn't have any size and may not appear as you are using wrap_content in the button definition
Try this:
<corners android:radius="30dp" />
<solid android:color="#android:color/white" />
<size
android:width="200dp"
android:height="50dp"/>
If you want an oval remove the corners tag and add android:shape="oval" as property of shape tag

Here is the code regarding button drawable background.
Xml code
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:gravity="center|top"
android:background="#color/colorLightPurple">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_marginTop="24dp"
android:background="#drawable/button_bg"
android:text="Search"
android:textColor="#color/colorBlue"/>
</LinearLayout>
For button background , please add same drawable file

seems like you're doing everything right. Just a small addition, try adding android:shape="rectangle" in the shape tag.
This is what button_capsule.xml should look like.
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners android:radius="1000dp" />
<solid android:color="#android:color/white" />
</shape>
Hope this works. All the best.

In Material design version 1.2.0 they have fixed this issue and added a property for setting background for Material Button
here is the dependency for the latest version
com.google.android.material:material:1.2.0
and also if u want to remove the space between the drawable top and bottom so that the drawable get the whole width and height use these 2 properties
android:insetTop="0dp"
android:insetBottom="0dp"
if want to explore more about the properties u can refer to the release of library and can check all the properties.
https://github.com/material-components/material-components-android/releases/tag/1.2.0

use this.
<androidx.appcompat.widget.AppCompatButton
.....
/>

Tinting the background of an outlined Material Components button

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"

DrawableLeft in center with text

I can't center my drawableLeft icon.
I can easily put icon on the left of text, but if I set gravity to center, then only text is centered, but no icon.
<Button
android:id="#+id/patient_list_button"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/patientList"
android:drawableLeft="#drawable/ic_icon_two_heads"
android:layout_marginBottom="15dp"
style="#style/darkBlueButtonWithImage"/>
This is what I want:
This is what I have:
<style name="darkBlueButtonWithImage">
<item name="android:drawablePadding">10dp</item>
<item name="android:textColor">#color/white</item>
<item name="android:paddingLeft">10dp</item>
<item name="android:background">#drawable/radius_dark_blue_button</item>
<item name="android:gravity">center_vertical|left</item>
<item name="android:drawableTint">#color/white</item> <!-- has to be set in activity.java -->
</style>
How can I achieve this?

Finally, after all these years, we have possibility to achieve such behavior in simple and intuitive way.
All you have to do is use MaterialButton from Google Material library. Then use style with icon. After that you can use app:iconGravity property and set it to textStart
<com.google.android.material.button.MaterialButton
style="#style/Widget.MaterialComponents.Button.Icon"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Some text"
app:iconGravity="textStart"
app:icon="#drawable/some_icon" />

The easiest solution IMO:
yourButtonView.text = SpannableString(" ${getString(R.string.your_string)}").apply {
setSpan(
ImageSpan(requireContext(), R.drawable.your_icon),
0,
1,
Spannable.SPAN_EXCLUSIVE_EXCLUSIVE
)
}
Is a bit hacky? Maybe. Does it work with every button (MaterialButton, AppCompatButton, Button, etc)? It does.
I prefer this rather than going with all the hassle of creating a custom view or something like that.

After giving Google's approach a try over 9000 times, I almost always ended up using a ViewGroup to put both side by side, particularly a RelativeLayout or LinearLayout and then adding an ImageView and a TextView. It's lame, but drawableStart/End have so many missing features that you'll waste a lot of time before you realize "you can't do it".
Alignments, tinting, Vectors, etc. All those things are harder or impossible with the "built in" drawable.

Using Button attributes android:drawableLeft and android:drawablePadding you won't be able to get your expected result. You can create a custom button using RelativeLayout or LinearLayout, TextView and ImageView. Use <selector> to define your button state(normal/pressed) behavior.
Here is an working example. Try this:
<!--- Custom Button -->
<RelativeLayout
android:id="#+id/patient_list_button"
android:layout_width="match_parent"
android:layout_height="48dp"
android:clickable="true"
android:background="#drawable/custom_button_selector">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_centerInParent="true"
android:gravity="center_vertical">
<ImageView
android:layout_width="24dp"
android:layout_height="24dp"
android:src="#drawable/icon_refresh"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="8dp"
android:textSize="16dp"
android:text="CUSTOM BUTTON"
android:textStyle="bold"
android:textColor="#FFFFFF"/>
</LinearLayout>
</RelativeLayout>
custom_button_selector.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_pressed="true"
android:state_enabled="true"
android:drawable="#drawable/bg_custom_button_pressed" />
<item
android:state_focused="true"
android:state_enabled="true"
android:drawable="#drawable/bg_custom_button_pressed" />
<item
android:state_enabled="true"
android:drawable="#drawable/bg_custom_button_normal" />
</selector>
bg_custom_button_normal.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<!-- view background color -->
<solid
android:color="#01A1DD" >
</solid>
<!-- Here is the corner radius -->
<corners android:radius="8dp" >
</corners>
</shape>
bg_custom_button_pressed.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<!-- view background color -->
<solid
android:color="#303F9F">
</solid>
<!-- Here is the corner radius -->
<corners android:radius="8dp" >
</corners>
</shape>
OUTPUT:
Hope this will help~

a) Increase "paddingLeft" value and shrink or remove "drawablePadding" in your case, adjust the value to a proper one; for example:
android:paddingLeft="50dp"
android:gravity="center_vertical|left"
b) Use a custom view.

A bit hacky solution:
<TextView
android:id="#+id/tv_whatsapp"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toLeftOf="#id/tv_call"
app:layout_constraintTop_toBottomOf="#id/tv_completed_message_desc"
android:layout_width="0dp"
android:layout_height="40dp"
android:textStyle="normal"
android:layout_marginTop="#dimen/rs_dp_13"
android:layout_marginRight="#dimen/rs_dp_12"
android:background="#drawable/rs_dark_teal_rectangle_bg"
android:textSize="14sp"
android:textColor="#color/dark_teal"
**android:paddingHorizontal="38dp"**
android:includeFontPadding="false"
**android:drawableStart="#drawable/rs_user_journey_whatsapp_icon"**
**android:drawableLeft="#drawable/rs_user_journey_whatsapp_icon"**
android:visibility="visible"
android:letterSpacing="0.04"
app:layout_constraintHorizontal_chainStyle="packed"
**android:gravity="center_vertical|end"**
android:text="Whatsapp"/>
Setting horizontal padding along with gravity as center_vertical|end will achieve the required behaviour. You can increase/decrease the padding as per requirement.

Android button background color

I am trying to set the background color of a button in my app and I am unable to achieve the result that I want...
The color that I am trying to set is holo_green_light(#ff99cc00). In order to do it, I am using setColorFilter(0xff99cc00, PorterDuff.Mode.MULTIPLY);
The color that I get is not the holo_green_light but a mix of lightgrey and holo_green_light.
I have tried using the LightingColorFilter without much success.
Is there a way to do it programatically, so that the button appears like a button and not a flat rectangle with the color that I need.

If you want to keep the general styling (rounded corners etc.) and just change the background color then I use the backgroundTint property
android:backgroundTint="#android:color/holo_green_light"

This is my way to do custom Button with a different color:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<stroke android:width="3dp"
android:color="#80FFFFFF" />
<corners android:radius="25dp" />
<gradient android:angle="270"
android:centerColor="#90150517"
android:endColor="#90150517"
android:startColor="#90150517" />
</shape>
This way you set as background:
<Button android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button"
android:layout_marginBottom="25dp"
android:layout_centerInParent="true"
android:background="#drawable/button" />

If you don't mind hardcoding it you can do this ~> android:background="#eeeeee" and drop any hex color # you wish.
Looks like this....
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_below="#+id/textView1"
android:text="#string/ClickMe"
android:background="#fff"/>

Create /res/drawable/button.xml with the following content :
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" android:padding="10dp">
<!-- you can use any color you want I used here gray color-->
<solid android:color="#90EE90"/>
<corners
android:bottomRightRadius="3dp"
android:bottomLeftRadius="3dp"
android:topLeftRadius="3dp"
android:topRightRadius="3dp"/>
</shape>
And then you can use the following :
<Button
android:id="#+id/button_save_prefs"
android:text="#string/save"
android:background="#drawable/button"/>

Just use a MaterialButton and the app:backgroundTint attribute:
<MaterialButton
app:backgroundTint="#color/my_color_selector"

Why not just use setBackgroundColor(getResources().getColor(R.color.holo_light_green))?
Edit: If you want to have something which looks more like an Android button you are going to want to create a gradient and set it as the background. For an example of this, you can check out this question.

No need to be that hardcore.
Try this :
YourButtonObject.setBackground(0xff99cc00);

Try this
<androidx.appcompat.widget.AppCompatButton
android:layout_width="wrap_content"
android:layout_height="34dp"
android:text="Check Out"
android:textAllCaps="true"
android:background="#54c2bc"
android:textColor="#FFFFFF"
android:textSize="9sp"/>

In order to keep the style, use:
int color = Color.parseColor("#99cc00");
button.getBackground().mutate().setColorFilter(new PorterDuffColorFilter(color, PorterDuff.Mode.SRC));

In addition to Mark Proctor's answer:
If you want to keep the default styling, but have a conditional coloring on the button, just set the backgroundTint property like so:
android:backgroundTint="#drawable/styles_mybutton"
Create the associated file /res/drawable/styles_mybutton.xml, then use the following template and change the colors as per your tastes:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Disabled state-->
<item android:state_enabled="false"
android:color="#android:color/white">
</item>
<!-- Default state-->
<item
android:color="#cfc">
</item>
</selector>

try this
app:backgroundTint="#color/colorGreen"

With version 1.2.0-alpha06 of material design library, now we can use android:background="..." on MaterialButton components:
<com.google.android.material.button.MaterialButton
android:background="#fff"
...
/>
