This is not working. How to change background color of floating action button

Answer 1

Using the material components FloatingActionButton and a material theme by default it uses the color with the attribute colorSecondary.

To change this color you have different options:

• You can use the app:backgroundTint attribute in xml:

<com.google.android.material.floatingactionbutton.FloatingActionButton
       ...
       app:backgroundTint=".." />

• You can use a custom style using the <item name="backgroundTint"> attribute

  <!--<item name="floatingActionButtonStyle">@style/Widget.MaterialComponents.FloatingActionButton</item> -->
  <style name="MyFloatingActionButton" parent="@style/Widget.MaterialComponents.FloatingActionButton">
    <item name="backgroundTint">....</item>
  </style>

• starting from version 1.1.0 of material components you can also use the new materialThemeOverlay attribute to override the default color colorSecondary only for a component:

  <style name="MyFloatingActionButton" parent="@style/Widget.MaterialComponents.FloatingActionButton">
    <item name="materialThemeOverlay">@style/MyFabOverlay</item>
  </style>

  <style name="MyFabOverlay">
    <item name="colorSecondary">@color/custom2</item>
  </style>

Answer 2

You can use this code to change the background color:

FloatingActionButton button = findViewById(R.id.your_button);
if (Build.VERSION.SDK_INT == Build.VERSION_CODES.LOLLIPOP && button instanceof AppCompatButton) {
    ((AppCompatButton) button).setSupportBackgroundTintList(ColorStateList.valueOf(*your color in integer*));
} else {
    ViewCompat.setBackgroundTintList(button, ColorStateList.valueOf(*your color in integer*));
}

Answer 3

Please try this.

app:backgroundTint="@android:color/darker_gray"

Answer 4

Simply use this attribute:

android:backgroundTint="@color/yourColor"

Answer 5

Your code is completely correct. I also wrote in a similar way for changing background color of floating action button programatically. Just check your xml code once. My XML Code :

<com.google.android.material.floatingactionbutton.FloatingActionButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentEnd="true"
    android:layout_alignParentBottom="true"
    app:borderWidth="0dp"
    android:id="@+id/fab"
    android:layout_margin="16dp"
    app:elevation="8dp"/>

Remember here, keeping borderWidth="0dp" is important. Now, in Java Code :

fab = view.findViewById(R.id.fab);
fab.setBackgroundTintList(ColorStateList.valueOf(required_color));

Here you can replace required_color using Color.parseColor() or ContextCompat.getColor().
