I have a Button and a ProgressBar inside a FrameLayout. How come my ProgressBar is visible only when Button is disabled? I'm running my app on android 6.0.1.
This is my layout file:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:padding="16dp">
    <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
        <Button
            android:id="@+id/btn_love"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="Love" />
        <ProgressBar
            android:id="@+id/progress_bar"
            style="?android:attr/indeterminateProgressStyle"
            android:layout_width="22dp"
            android:layout_height="22dp"
            android:layout_gravity="right|center_vertical"
            android:layout_marginRight="16dp" />
    </FrameLayout>
</LinearLayout>
