TextView Ignores textAlignment Property

Question

My Xamarin.Android app recently started ignoring the textAlignment property of all the TextView(s). This started happening very unexpectedly in multiple places with no significant changes in code. Also, the Designer in Visual Studio 2019 still shows the correct rendering, even though the app does not. Here are screenshots of the Designer and Emulator:

Here is the code for the TextView & Style Resource:

<TextView android:layout_row="0" style="@style/PopupHeaderTextViewStyle" android:textAlignment="center" android:text="Player Names"/>  

<style name="PopupHeaderTextViewStyle">  
	<item name="android:layout_width">match_parent</item>  
	<item name="android:layout_height">wrap_content</item>  
	<item name="android:textAlignment">center</item>  
	<item name="android:fontFamily">@font/arialfamily</item>  
	<item name="android:textStyle">bold</item>  
	<item name="android:textSize">30dp</item>  
	<item name="android:textColor">@color/Black</item>  
</style>  

Note that the textAlignment property is included in the Style & inline. As previously stated, this issue started occuring in all places, both static & dynamic. Because the issue started in completely unrelated places at the same time, it leads me to believe that it was not caused by my code, but I cannot figure out what could have caused the problem or how to fix it.

Answer 1

I think I found the solution. In the Application (the class that inherits from Application), I had to add SupportsRtl=true in the Application attribute, as follows:

[Application(Debuggable = true, SupportsRtl = true)]
public class ScorePadApplication : Application

If SupportsRtl is set to false or not specified (which is what it was before), it ignored android:textAlignment, but now it works. I don't know why it was working before if this is necessary, but it seems to have solved the problem. Hopefully this can help anyone else that has this problem.

Hello,​

Welcome to our Microsoft Q&A platform!

I used your code in my VS 2019 Version 16.10.0, my emulator and xaml previewer are work normally, please see the following screenshot

You can try to delete following code in your PopupHeaderTextViewStyle

   <item name="android:layout_width">match_parent</item>  
        <item name="android:layout_height">wrap_content</item>  

Then set android:layout_width and android:layout_height directly in TextView

   <TextView   
           android:layout_row="0"  
           android:layout_width="match_parent"  
           android:layout_height="wrap_content"  
           style="@style/PopupHeaderTextViewStyle"   
           android:textAlignment="center"   
           android:text="Player Names"/>
