Red Circle Around Custom Android Button Image - android

I have created a floating action button, and made my own image (at each of dpi sizes), but there is a red circle around it (image below). Here is my xml defining the button
<android.support.design.widget.FloatingActionButton
android:id="#+id/addplant"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="end|bottom"
android:layout_margin="#dimen/fab_margin"
android:src="#mipmap/add_plant"/>
Here is my source image (#192x192), and a screenshot of what i'm seeing in android studio.


You can try the below -
<android.support.design.widget.FloatingActionButton
...
...
android:src="#drawable/icon" // change backgroung icon
app:backgroundTint="#android:color/transparent" // change background color
/>
setting tint to transparent will override that primary color pink you have given in styles.


Try using XML attribute app:backgroundTint
<android.support.design.widget.FloatingActionButton
android:id="#+id/addplant"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="end|bottom"
android:layout_margin="#dimen/fab_margin"
app:backgroundTint="#color/orange" // -----> your background color
android:src="#mipmap/add_plant" />


EDIT 2
No need to use app:backgroundTint juse USE android:scaleType="center" in your FloatingActionButton it will work
<android.support.design.widget.FloatingActionButton
android:id="#+id/addplant"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="end|bottom"
android:layout_margin="#dimen/fab_margin"
android:scaleType="center"
android:src="#mipmap/add_plant" />
OUTPUT
Try this
<android.support.design.widget.FloatingActionButton
android:id="#+id/addplant"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="end|bottom"
android:layout_margin="#dimen/fab_margin"
android:src="#drawable/add_plant"/>
android:src="#drawable/add_plant"
<vector xmlns:android="http://schemas.android.com/apk/res/android"
android:width="24dp"
android:height="24dp"
android:viewportWidth="24.0"
android:viewportHeight="24.0">
<path
android:fillColor="#FFFFFF"
android:pathData="M19,13h-6v6h-2v-6H5v-2h6V5h2v6h6v2z"/>
</vector>
OUTPUT
EDIT
To support vector drawablea add this in your build.gradle file
defaultConfig {
vectorDrawables.useSupportLibrary = true
}


Use this
app:useCompatPadding="true"


Just use the + symbol alone as source. You need not pass the whole image with green background. To set the green background color use app:backgroundTint="#color/green"
Change your code like this and use green color for backgroundTint and plus icon as source:
<android.support.design.widget.FloatingActionButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:backgroundTint="#color/green"
android:src="#drawable/ic_plus" />


You can use background color
app:backgroundTint="#color/green"
remove background color from image, use image without background https://cdn.pixabay.com/photo/2016/10/10/01/49/plus-1727487__340.png
<android.support.design.widget.FloatingActionButton
android:id="#+id/addplant"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="end|bottom"
android:layout_margin="#dimen/fab_margin"
app:backgroundTint="#color/green"
android:src="#mipmap/add_plant"/>


Because Floating action button is colored by the colorAccent attribute in your theme. you can set the background tint to green. I have updated your code.
<android.support.design.widget.FloatingActionButton
android:id="#+id/addplant"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="end|bottom"
android:layout_margin="#dimen/fab_margin"
android:backgroundTint="#4CAF50"
android:src="#mipmap/add_plant"/>

How to set border and background color of Floating Action Button with transparency through xml?

I have tried this solution: https://stackoverflow.com/a/54074154/10299002
which works great as long as the FAB is over a dark background. However, it seems to break when it passes over a white background. What might be the issue?
Here is my FAB:
<com.google.android.material.floatingactionbutton.FloatingActionButton
android:theme = "?appAccentStyle"
android:id="#+id/button_fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:visibility="invisible"
android:layout_margin="16dp"
app:backgroundTint="?colorFloatingActionButtonBorder"
android:src="#drawable/ic_arrow_downward_24dp"
android:tint="?colorAccent"
android:backgroundTint="?colorFloatingActionButtonBackground"
tools:visibility="visible"
android:layout_gravity="end|bottom" />
This is the style being applied:
<style name="LimeColorAccent">
<item name="colorAccent">#color/Lime</item>
<item name="appAccentStyle">#style/LimeColorAccent</item>
<item name="colorFloatingActionButtonBorder">#color/LimeTranslucentBorder</item>
<item name="colorFloatingActionButtonBackground">#color/LimeTranslucent</item>
</style>
And here are the colors used:
<color name="Lime">#FFCDDC39</color>
<color name="LimeTranslucentBorder">#4cCDDC39</color>
<color name="LimeTranslucent">#26CDDC39</color>
Output:

app:backgroundTint="#55990000"
app:borderWidth="0dp"
app:elevation="2dp"
tools:visibility="visible" />
Output: (Inner Circle Still Broken)

I used you code and directly used color. and found two result with black background and white background .
and the code:
<com.google.android.material.floatingactionbutton.FloatingActionButton
android:id="#+id/button_fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:visibility="visible"
android:layout_margin="16dp"
app:backgroundTint="#4cCDDC39"
android:src="#drawable/ic_action_profile"
android:tint="#color/colorAccent"
app:borderWidth="2dp"
android:backgroundTint="#26CDDC39"
tools:visibility="visible"
android:layout_gravity="end|bottom" />

You should create your own FAB style extending com.google.android.material.floatingactionbutton.FloatingActionButton as parent, to properly custom your button.
Check out this answer, it should help you. The idea is to create your own border.
FloatingActionButton only provides app:borderWidth to play with border thickness.

How to change Floating Button border color?

I want to change the floating button border color. I have try the code from multiple sources but didn't get satisfying answer. Please tell me is it possible to change the border color of floating button in android. Looking forward to get positive response. Thanks
Code:
<android.support.design.widget.FloatingActionButton
android:id="#+id/response_btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="#dimen/fab_margin"
android:clickable="true"
android:scaleType="center"
android:background="#drawable/ring"
android:src="#drawable/btn_fab_calendar_add"
android:tint="#color/white"
android:adjustViewBounds="true"
app:fabSize="normal"
app:borderWidth="0dp"
app:layout_anchor="#id/appbar"
app:layout_anchorGravity="bottom|right|end"
app:rippleColor="#color/gray"
android:visibility="visible"
app:pressedTranslationZ="12dp"/>

How to remove grey shadow color below FloatingActionButton

I am getting light grey color below the FloatingActionButton as shown in image. Any one know how to remove it. I tested it on Lollipop version.
My xml code
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:src="#drawable/ic_add_black"
app:borderWidth="0dp"
app:fabSize="mini"
app:rippleColor="#color/colorPrimaryDark" />

Try set elevation:
app:elevation="0dp"

It happens when you set an elevation and the fab element has not space enough to display the "shadow".
Then you can set the elevation as 0dp as suggested above, or set a margin like
<android.support.design.widget.FloatingActionButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_build_white_36dp"
android:id="#+id/build"
app:elevation="4dp"
android:clickable="true"
android:layout_margin="10dp"
android:layout_alignParentBottom="true"
android:layout_alignParentEnd="true" />
In this way the "elevation-effect" will appear correctly

Setting src and background for FloatingActionButton

When I use background and src in android.support.design.FloatingActionbutton it is not set correctly. Instead it is displayed as
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/pink"
android:src="#drawable/ic_action_barcode_2"
android:layout_gravity="bottom|right"
android:layout_marginBottom="16dp"
android:layout_marginRight="16dp" />
but when I use ImageView it appears correctly as
<ImageView
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/pink"
android:src="#drawable/ic_action_barcode_2"
android:layout_gravity="bottom|right"
android:layout_marginBottom="16dp"
android:layout_marginRight="16dp" />
why is FloatingActionButton is not displayed correctly? What should I change in my code?

Floating action button's background does not need to be changed, you just apply a tint and then add your icon as usual
<android.support.design.widget.FloatingActionButton
...
app:backgroundTint="#color/ic_action_barcode_2"
android:src="#drawable/ic_add" />
This provides you with a round button still but in the colour you desire.
In this case the app namespace is used for the support library features:
xmlns:app="http://schemas.android.com/apk/res-auto"

i faced the similar problem. I tried to set src or background of FloatingActionButton, but couldn't fill the button by src. following code solved problem for me.
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
.
.
.
android:background="#drawable/round_icon"
android:backgroundTintMode="src_over">

Set FAB icon color

current FAB
I would like to know how to change the icon color of the FAB (Floating Action Button) widget supplied by the 'com.android.support:design:22.2.0' library from green to white.

android:src="#android:drawable/ic_input_add"
android:layout_margin="24dp"
app:elevation="6dp"
app:pressedTranslationZ="12dp"
app:borderWidth="0dp" />

UPDATE 2
If you are using com.google.android.material.floatingactionbutton.FloatingActionButton, use app:tint
app:tint="#android:color/white"
UPDATE
Refer to the answer of #Saleem Khan which is the standard way to set the app:tint using:
android:tint="#android:color/white"
via XML on FloatingActionButton.
OLD (June 2015)
This answer was written before October 2015, when android:tint on FloatingActionButton was supported only with API >= 21.
You can change it programmatically using ColorFilter.
//get the drawable
Drawable myFabSrc = getResources().getDrawable(android.R.drawable.ic_input_add);
//copy it in a new one
Drawable willBeWhite = myFabSrc.getConstantState().newDrawable();
//set the color filter, you can use also Mode.SRC_ATOP
willBeWhite.mutate().setColorFilter(Color.WHITE, PorterDuff.Mode.MULTIPLY);
//set it to your fab button initialized before
myFabName.setImageDrawable(willBeWhite);

Using android:tint property you can set the color like this
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:tint="#android:color/white"
android:src="#android:drawable/ic_input_add"
/>

If you are using Material Components
<com.google.android.material.floatingactionbutton.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="16dp"
android:layout_gravity="bottom|end"
app:fabSize="normal"
app:tint="#color/colorAccent"
app:srcCompat="#drawable/ic_google"/>
If you want to use icon default color, change app:tint="#null"

You have to change app:tint for that to work. android:tint didn't do any change for me.

It's easier than get the drawables, you only need to access to the color filter and set it to the color that you want.
FloatingActionButton myFab = (FloatingActionButton) findViewById(R.id.myfabid);
myFab.setColorFilter(Color.WHITE);

Since FloatingActionButton extends ImageView we can use ImageViewCompat to tint the icon:
ImageViewCompat.setImageTintList(
floatingActionButton,
ColorStateList.valueOf(Color.WHITE)
);

Use the white version of ic_add from the google design site.
android:tint looks like a clean solution but it is not supported below API level 21
Using a bitmap adds less complexity to your app than attempting to change the color of an existing icon programmatically. Less complexity means fewer things to test :)

Try this code
<com.google.android.material.floatingactionbutton.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:backgroundTint="#color/sm_blue"
app:tint="#color/white"
android:layout_margin="#dimen/fab_margin"
app:srcCompat="#android:drawable/ic_input_add" />
Result

If you are using material FAB use app:tint to change the color of the icon instead of android:tint

If you want to change the color of the icon in CollapsingToolbarLayout use the following code
app:tint="#color/white"
Use the app instead of Android

<com.google.android.material.floatingactionbutton.FloatingActionButton
android:id="#+id/add_loan"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="#dimen/medium"
android:layout_marginBottom="16dp"
android:backgroundTint="#color/ci_blue"
android:theme="#style/fabtheme"
app:srcCompat="#drawable/ic_baseline_add_24"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_bias="1"
app:layout_constraintStart_toStartOf="parent"
app:rippleColor="#color/white" />
theme
<style name="fabtheme" parent="Widget.Design.FloatingActionButton">
<item name="colorOnSecondary">#color/white</item>
</style>
or
use the attribute
app:tint="#color/white"

For API >= 21
My Solution to change FloatingActionButton icon color programmatically
val fab = FloatingActionButton(requireContext())
fab.apply {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
imageTintList = ColorStateList.valueOf(Color.WHITE)
}

You can make your custom style:
<style name="FloatingButton" parent="Widget.MaterialComponents.FloatingActionButton">
<item name="colorSecondary">#color/red</item>
<item name="colorOnSecondary">#color/white</item>
</style>
Where colorSecondary is the background and colorOnSecondary is the color of the drawable of the button.
<com.google.android.material.floatingactionbutton.FloatingActionButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_phone"
android:theme="#style/FloatingButton" />

If you are using com.google.android.material.floatingactionbutton.FloatingActionButton
Then
To change Background Color of Floating Action Button, use app:backgroundTint
To change Floating Action Button's Icon's color, use app:tint
To change Floating Action Button's Icon Drawable, use app:srcCompat
<com.google.android.material.floatingactionbutton.FloatingActionButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:backgroundTint="#color/white"
app:srcCompat="#drawable/fb_icon"
app:tint="#android:color/black" />

If you are using material FAB, you can style it programmatically using the below code in Kotlin.
fab.supportImageTintList = ContextCompat.getColorStateList(context, R.color.fab_icon_tint)

If you use Extended, set app:iconTint you can do like this:
<com.google.android.material.floatingactionbutton.ExtendedFloatingActionButton
android:id="#+id/fAB"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginEnd="16dp"
android:layout_marginBottom="16dp"
android:clickable="true"
android:focusable="true"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:icon="#drawable/d0"
app:iconTint="#color/white"
app:shapeAppearanceOverlay="#style/ShapeAppearanceOverlay.Material3.FloatingActionButton"
tools:ignore="SpeakableTextPresentCheck" />

This will keep the original color of the icon.
app:tint="#null"
or
android:tint="#null"

In Java
private FloatingActionButton login;
login = findViewById(R.id.loginbtn);
login.setColorFilter(android.R.color.white);
In XML
<com.google.android.material.floatingactionbutton.FloatingActionButton
android:id="#+id/loginbtn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:backgroundTint="#color/colorPrimaryDark"
android:src="#drawable/loginicon"
app:rippleColor="#color/white"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/pass_l" />
