Any idea why AppCompatTextView (AndroidX) with autoSizeTextType is not working in Tablets and Compat theme?

I tried the following combinations and all look exactly the same:

                android:visibility="invisible" />  
        </LinearLayout>  
    </LinearLayout>  
</ScrollView>

My style is this one:

<style name="Theme.GNowTheme" parent="Theme.AppCompat">  
    <item name="android:colorPrimary">#000000</item>  
    <item name="android:colorPrimaryDark">#000000</item>  
    <item name="android:textColor">#BEBEBE</item>  
    <item name="android:textColorPrimary">#FFFFFF</item>  
</style>

You can check the app here (it's written in Xamarin.Android):

Any idea what am I doing wrong? Thanks.

P.S.:

Any idea why the android:maxWidth="128dip" is not working also?
I'm testing in a Nexus 10 with Android 11 in an Emulator.

Please test it in your actual device, And I notice you use Huawei device, Does this device install the EMUI? If yes, please install the native android os.

Hi Leon,

I don't have a 10" Tablet to test that's why I use a Nexus 10 running Android 11 as I shared in my question. Also, I tested in a Huawei Emulator and the issue is the same.

Thanks.

Try to change the android:autoSizeTextType="uniform" to app:autoSizeTextType="uniform" make a test.

Hi Leon, I had already tried that:

 <!-- AppCompatTextView with android: option -->
 <androidx.appcompat.widget.AppCompatTextView
     android:text="@string/lblYourWeight"
     android:layout_width="match_parent"
     android:gravity="center_horizontal"
     android:textStyle="bold"
     android:autoSizeTextType="uniform"
     android:autoSizeMinTextSize="16sp"
     android:autoSizeMaxTextSize="100sp"
     android:autoSizeStepGranularity="2sp" />

 <!-- AppCompatTextView with app: option -->
 <androidx.appcompat.widget.AppCompatTextView
     android:text="@string/lblYourWeight"
     android:layout_width="match_parent"
     android:gravity="center_horizontal"
     android:textStyle="bold"
     app:autoSizeTextType="uniform"
     app:autoSizeMinTextSize="16sp"
     app:autoSizeMaxTextSize="100sp"
     app:autoSizeStepGranularity="2sp" />

Maybe you mean a different combination?

Hi I notice you do not set the layout_height to AppCompatTextView, And I find I set the android:layout_height="wrap_content", AppCompatTextView the autosize will not work, But if I set specific value, it worked like this screenshot.

Any idea why AppCompatTextView (AndroidX) with autoSizeTextType is not working in Tablets and Compat theme?
