Change color of Floating Action Button from Appcompat 22.2.0 programmatically

问题

I would like to know how to change the Floating Action Button color from the Support library 22.2.0 ? I've tried

button.setBackgroundColor(color);

but clearly, this changes the drawable of the button and it turns to a square.

Now I wonder how to change the color but just the color, without touching the shape?

Thanks in advance

回答1:

Maybe late but could help.

 fab.setBackgroundTintList(ColorStateList.valueOf(Color
                    .parseColor("#33691E")));

and parse the actual color code from a list of colors You can find here

回答2:

Create a ColorStateList and set it as the background tint:

button.setBackgroundTintList(new ColorStateList(new int[][]{new int[]{0}}, new int[]{color}));

回答3:

you have to use

in XML with attribute app:backgroundTint
in code with .setBackgroundTintList read this answer

回答4:

Create a color resource in colors.xml (R.color.purple in this case) and use it like so:

floatingActionButton.setBackgroundTintList(getResources().getColorStateList(R.color.purple));

Method 1: Change floating action bar(fab) color in xml:

To change floating action bar(fab) color just follow this step

just add "app:backgroundTint="#colorcode" " in xml of floating action bar(fab) .. For example

app:backgroundTint="#8393ca"

at the place of #8393ca add any color code you want

Example as usaage..

<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:layout_margin="@dimen/fab_margin"
    app:backgroundTint="#8393ca"
    android:src="@drawable/send" />

Method 2: Change floating action bar color programmatically

just add this line on your code

Firstly create a color red in your values=>colors then add this code in your activity on create

fab.setBackgroundTintList(getResources().getColorStateList(R.color.red));

                                or

fab.setBackgroundTintList(ColorStateList.valueOf(Color.parseColor("#33691E")));

回答6:

To do this backwards compatible:

DrawableCompat.setTintList(DrawableCompat.wrap(fab.getDrawable()), tintColor); // <- icon
DrawableCompat.setTintList(DrawableCompat.wrap(fab.getBackground()), backgroundTintColor); // <- background

Check the accepted answer here: Android changing Floating Action Button color

If you wish to change the color

in XML with attribute app:backgroundTint

in code with .setBackgroundTintList

回答8:

the attribute name is backgroundTint

so I thinks there's a function named

button.setBackgroundTint(color)

回答9:

if you are using Floating action button library from https://github.com/Clans/FloatingActionButton then use this

fab.setColorNormal(getResources().getColor(R.color.fab_color1));

回答10:

Try this code. It will add a tint to the background resource.

button.setBackgroundTintList(getResources().getColorStateList(R.color.yourColor));

回答11:

The XML background:tint color will always override whatever color you gave programmatically. So to give color programmatically, remove android:backgroundTint="#96989A" line from the XML file and use:

button.setBackgroundTintList(getResources().getColorStateList(R.color.yourColor));

回答12:

just use this line in your xml file under floating action button

android:backgroundTint="#96989A"
