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).

Solution 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:indeterminateAnimationType="contiguous"/>

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

Jetpack compose

With 1.0.x you can use the LinearProgressIndicator or CircularProgressIndicator

// Indeterminate
CircularProgressIndicator()
LinearProgressIndicator()

// Determinate
CircularProgressIndicator(progress = ..)
LinearProgressIndicator(progress = ..)

Example:

var progress by remember {  mutableStateOf(0.1f) }

LinearProgressIndicator(
    backgroundColor = Color.White,
    progress = progress,
    color = Blue
)

---

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.

Solution 2

This is an answer to an old question, but I figured fellow readers might be interested in this solution:

Newer versions (26.1.+) of the Support Library contain a class called CircularProgressDrawable that implements the exact look of the native Material indeterminate drawable. In order to easily use this in a layout, you can build a MaterialProgressBar like this:

public class MaterialProgressBar extends ProgressBar{
    // Same dimensions as medium-sized native Material progress bar
    private static final int RADIUS_DP = 16;
    private static final int WIDTH_DP = 4;

    public MaterialProgressView(Context context, AttributeSet attrs) {
        super(context, attrs);

        // The version range is more or less arbitrary - you might want to modify it
        if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP
                || Build.VERSION.SDK_INT > Build.VERSION_CODES.O_MR1) {

            final DisplayMetrics metrics = getResources().getDisplayMetrics();
            final float screenDensity = metrics.density;

            CircularProgressDrawable drawable = new CircularProgressDrawable(context);
            drawable.setColorSchemeColors(getResources().getColor(R.color.colorPrimary));
            drawable.setCenterRadius(RADIUS_DP * screenDensity);
            drawable.setStrokeWidth(WIDTH_DP * screenDensity);
            setIndeterminateDrawable(drawable);
        }
    }
}

How to use this as intederminate progressbar in action bar with webView?

[Robert Baker]

Like to add that this will not work for indeterminate circle bars. They lack the animated vector drawable.

[Richard Le Mesurier]

@Robert any hint how to do the same thing for indeterminate circles? This is one of the top results I could get to with my google-fu.

[gnuf]

@RichardLeMesurier You could try including this implementation, from Chromium. It doesn't make use of vector drawables: chromium.googlesource.com/android_tools/+/master/sdk/extras/‌​…

[Albert Vila Calvo]

If you want it centered on the screen, use wrap_content for both width and height, and add android:layout_gravity="center" (assuming that you are using a FrameLayout).

[BladeCoder]

This answer only describes how to use the platform's native progress bar. On pre-lollipop devices you'll end up with an untinted holo progress bar. This does not answer the question.

style="@style/Widget.AppCompat.ProgressBar.Horizontal"

so it works on material 1.3 and up, and i was wondering why it gives me unresolved error the whole time
