    android - Static background for ProgressBar - Stack Overflow

    programmeradmin4浏览0评论

    I want to have a ProgressBar with a static grey circle behind. Please check screenshot attached.

    My current code looks like this:

    main_layout.xml

        <View
        android:layout_width="48dp"
        android:layout_height="48dp"
        android:layout_gravity="center"
        android:background="@drawable/progress_bar_background"
        android:layout_marginBottom="-48dp" />

    <ProgressBar
        android:id="@+id/process_loading_circle"
        style="?android:attr/progressBarStyle"
        android:layout_width="48dp"
        android:layout_height="48dp"
        android:layout_gravity="center"
        android:indeterminateTint="@color/limeGreen" />

    progress_bar_background.xml

    <?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android=";
    android:shape="ring">
    <solid android:color="@color/grey" />
    <size android:width="48dp" android:height="48dp" />
    <stroke android:thickness="4dp" android:thicknessRatio="2" />
</shape>

    Just out of curiosity, I checked all of the shapes (line,ring,rectangle,oval) and it only works with oval and rectangle... ring is not being displayed at all.

    Reset to default 1

    Use CircularProgressIndicator from the material library:

    <com.google.android.material.progressindicator.CircularProgressIndicator
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

    Configure the track color and thickness with trackColor and trackThickness attributes.

    So my solution as @sdex wrote was to add the CircularProgressIndicator and my code looks like this

    1)Create a style in themes.xml

    <style name="CustomCircularProgressIndicator" parent="Widget.MaterialComponents.CircularProgressIndicator">
    <item name="indicatorColor">@color/limeGreen</item>
    <item name="trackColor">@color/grey</item>
</style>

    2)Add MaterialComponents to Base.Theme style

    <style name="Base.Theme.YOURAPP" parent="Theme.MaterialComponents.DayNight.NoActionBar">

    3)Lastly update your CircularProgressIndicator

      <com.google.android.material.progressindicator.CircularProgressIndicator
        android:layout_width="48dp"
        android:layout_height="48dp"
        android:layout_gravity="center"
        android:indeterminate="true"
        style="@style/CustomCircularProgressIndicator" />
