Hey @Aryan What is your Theme. Did you set theme as per requirement. I am pretty sure the color of button is because of theme you set to app — Ankit Tale, Nov 24 '20 at 08:18

@AryanKalekar use `android:backgroundTint` instead of background — Raghunandan, Nov 24 '20 at 08:30

Just close the xml and reopen it. You will be able to find the defined color in your xml view. There is nothing to do with theme. Its just Android studio xml updation delay.

If it is not working then add below line to your Button tag

app:backgroundTint="your color code"

Add this to your drawable

<shape xmlns:android="http://schemas.android.com/apk/res/android"

    android:shape="rectangle">

    <solid android:color="#156667"/>
    <corners android:radius="5dp"/>

</shape>

and apply it to your button's background in xml, you can change the color on <solid android:color="yourColor"/> there.

Since you are using a Theme.MaterialComponents.* theme the Button is replaced with a MaterialButton and by default has the backgroundTint based on the colorPrimary defined in your app theme

Use the backgroundTint attribute to change your color.

You shouldn't use the android:background attribute to change the color but if you want to use it to define a custom background you have to avoid that the button is tinted using:

<Button
    app:backgroundTint="@null"/>

Also using the android:background attribute the MaterialButton doesn't use its own MaterialShapeDrawable for the background. This means that features like shape appearance, stroke and rounded corners are ignored.

thanks sir for your detailed ans. i m sure next time i will be using this info — Aryan Kalekar, Nov 24 '20 at 15:16
