When I use `android:background` with `Button` this appearance of the button does not change but when I use this with `TextView` or `ImageButton` it works correctly. The problem occurs in all layout files in project.

How to fix this ?

activity.xml

```
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    //Not working
    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/button"/>

    /Working
    <ImageButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/button"
        android:layout_marginLeft="100dp"/>

</RelativeLayout>

```

AndroidManifest.xml

```xml
        android:largeHeap="true"
        android:supportsRtl="true"
        android:theme="@style/Theme.MaterialComponents.Light.NoActionBar">
        <activity android:name=".Activity.AddTaskActivity"></activity>
        <activity android:name=".Activity.AddActivity" />
        <activity android:name=".TutorialActivity" />
        <activity android:name=".PlanNextDayActivity" />

        <service
            android:name=".FirebaseMessages"
            android:enabled="true"
            android:exported="true" /> 
        <meta-data
            android:name="com.google.android.gms.ads.APPLICATION_ID"
            android:value="ca-app-pub-3940256099942544~3347511713" />

        <activity android:name=".BuyPremiumActivity" />
        <activity
            android:name=".SelectColor"
            android:screenOrientation="sensorPortrait" />
        <activity
            android:name=".MainActivity"
            android:screenOrientation="sensorPortrait">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity
            android:name=".Activity.SelectIconActivity"
            android:screenOrientation="sensorPortrait" />
        <activity
            android:name=".Activity.AddReminder"
            android:screenOrientation="sensorPortrait" />
