Android - Tinting ProgressBar on pre-Lollipop devices

Question

My app's minimum API-level is 19 (KitKat), and contains a layout with a horizontal ProgressBar. I'm using android:progressTint attribute to tint the bar to a custom color. It works pretty well on Lollipop (API 21) and above, but below (for example on API 19) it doesn't; it shows up in a different color. The reason is that this attribute

is only used in API level 21 and higher

as Android Studio states.

So I'm wondering what can be a good alternative for tinting the ProgressBar on pre-Lollipop devices, too. Can it be made inside the layout file with XML? Or should this be done on a different way?

EDIT #1: My ProgressBar is used to show concrete values in percents, not for indicating that my layout is loading. I want to make this clear because after trying what Kuldeep Kulkarni wrote below, my bar looked like a material loading indicator (of course on the Lollipop device, not any visible result on KitKat device).

Answer 1

You can wrap with ProgressBar indeterminateDrawable method for pre-Lollipop.

if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {

     Drawable drawableProgress = DrawableCompat.wrap(progressBar.getIndeterminateDrawable());
     DrawableCompat.setTint(drawableProgress, ContextCompat.getColor(getContext(), android.R.color.holo_green_light));
     progressBar.setIndeterminateDrawable(DrawableCompat.unwrap(drawableProgress));

} else {
    progressBar.getIndeterminateDrawable().setColorFilter(ContextCompat.getColor(getContext(), android.R.color.holo_green_light), PorterDuff.Mode.SRC_IN);
}

Answer 2

progress.getProgressDrawable().setColorFilter(color, PorterDuff.Mode.SRC_IN);

Thanks for the suggestions from everyone! :)

The solution which works for me is to create a custom drawable XML file with the <layer-list> root element. There, I'm defining two layer items with the native Android IDs @android:id/background and @android:id/progress. After this, I can define the shapes and color resources I would like to use. This solution is similar to a more popular answer on this SO question.

Content of my res/drawable/progressbar.xml file:

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:id="@android:id/background">

        <shape>

            <corners android:radius="2dip" /> <!--optional-->

            <gradient
                android:angle="270"
                android:endColor="@color/gray"
                android:startColor="@color/gray" />

        </shape>

    </item>

    <item android:id="@android:id/progress">

        <clip>

            <shape>

                <corners android:radius="2dip" /> <!--optional-->

                <gradient
                    android:angle="270"
                    android:endColor="@color/blue"
                    android:startColor="@color/blue" />

            </shape>

        </clip>

    </item>

</layer-list>

Defined as progressDrawable for my ProgressBar in the layout XML file:

<ProgressBar
        android:id="@+id/progress_bar"
        android:layout_width="0dp"
        android:layout_height="@dimen/progress_bar_height"
        android:progressDrawable="@drawable/progressbar" />

I didn't have a chance to test it below API 19, but on this level and above it works perfectly.

This works for me

<ProgressBar
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:theme="@style/progressBarBlue" />

Then in your style.xml define progressBarBlue

<style name="progressBarWhite" parent="@style/Theme.AppCompat">
   <item name="colorAccent">@color/blue</item>
</style>
