When is indeterminate progressbar coming to Android Support Library

Question

My applications UI is built using the Android Support Library, but there is currently no AppCompat version of the (intederminate) progressbar, which my app really needs.

I would prefer to not use any third party libraries to achieve material design progressbars, so I'm wondering if anyone sits on information about why it's not included in the support library, and if there is any sign of it arriving (and when).

Answer 1

Material Components Library

You can use the LinearProgressIndicator with the android:indeterminate="true" attribute:

<com.google.android.material.progressindicator.LinearProgressIndicator
    android:indeterminate="true"
    app:indicatorColor="?attr/colorPrimary"/>

You can also use different colors using:

<com.google.android.material.progressindicator.LinearProgressIndicator
        android:indeterminate="true"
        app:indicatorColor="@array/progress_colors"
        app:growMode="outgoing"/>

with:

  <integer-array name="progress_colors">
    <item>@color/...</item>
    <item>@color/....</item>
    <item>@color/....</item>
  </integer-array>

You can also use the CircularProgressIndicator component to have a circular progress indicator:

<com.google.android.material.progressindicator.CircularProgressIndicator
    android:indeterminate="true"
    app:indicatorColor="?attr/colorPrimary"/>

Note: It requires at least the version 1.3.0-alpha04

AppCompat

You can use a ProgressBar with an AppCompat style.

Just add this in your layout:

<ProgressBar
        style="@style/Base.Widget.AppCompat.ProgressBar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:indeterminate="true"
        android:visibility="visible" />

If you would like an Horizontal progress bar use:

  <ProgressBar
        style="@style/Base.Widget.AppCompat.ProgressBar.Horizontal"
        android:layout_width="match_parent"
        android:layout_height="8dp"
        android:layout_marginTop="24dp"
        android:indeterminate="true"
        android:visibility="visible" />

They follow the official material guidelines.
