How to align View vertically to the text inside TextView?

I'm trying to achieve this result:

What I have right now it is ConstraintLayout which includes three Views: TextView, ImageView, ImageView

Design requirements:

1. Text centered inside TextView;
2. TextView has fixed size 80dp
3. Size of text should be AutoSizeable;
4. ImageViews should change position horizontally depending on text position inside TextView. See images with case #1/#2 for reference.

Is it possible to achieve item 4 in XML? What about programmatically?

[Additional info]

Autosizing doesn't work properly with width wrap_content, see autosizing documentation:

Note: If you set autosizing in an XML file, it is not recommended to use the value "wrap_content" for the layout_width or layout_height attributes of a TextView. It may produce unexpected results.

So after an investigation found two solutions for this:

• Calculation of text width and applying a horizontal bias to ImageViews;
• Custom text view - AutoResizeTextView;

In the first case, we get actual width of text in the TextView:

Rect bounds = new Rect();
textView.getPaint().getTextBounds(textView.getText().toString(), 0, textView.getText().length(), bounds);
float width = bounds.width();

And then apply simple math to calculate horizontal bias for ImageViews.

Second option is to add custom view. It is differ from autosizing-textview . It will resize text after measuring in onLayout. And in onTextChanged we reset text size without resizing. Ellipsizing it's an additional feature which may be useful in some cases.

/**
 * Text view that auto adjusts text size to fit within the view.
 * If the text size equals the minimum text size and still does not
 * fit, append with an ellipsis.
 */
public class AutoResizeTextView extends android.support.v7.widget.AppCompatTextView {

    // Minimum text size for this text view
    public static final float MIN_TEXT_SIZE = 20;

    // Interface for resize notifications
    public interface OnTextResizeListener {
        public void onTextResize(TextView textView, float oldSize, float newSize);
    }

    // Our ellipse string
    private static final String mEllipsis = "...";

    // Registered resize listener
    private OnTextResizeListener mTextResizeListener;

    // Flag for text and/or size changes to force a resize
    private boolean mNeedsResize = false;

    // Text size that is set from code. This acts as a starting point for resizing
    private float mTextSize;

    // Temporary upper bounds on the starting text size
    private float mMaxTextSize = 0;

    // Lower bounds for text size
    private float mMinTextSize = MIN_TEXT_SIZE;

    // Text view line spacing multiplier
    private float mSpacingMult = 1.0f;

    // Text view additional line spacing
    private float mSpacingAdd = 0.0f;

    // Add ellipsis to text that overflows at the smallest text size
    private boolean mAddEllipsis = true;

    // Default constructor override
    public AutoResizeTextView(Context context) {
        this(context, null);
    }
