You need to use AppCompatEdittext you can change to any view which listening the text inputs.
Step 1
Create file named  chip.xml and Add resource in the following folder.
<?xml version="1.0" encoding="utf-8"?>
<chip xmlns:android="http://schemas.android.com/apk/res/android"
 xmlns:app="http://schemas.android.com/apk/res-auto"
 android:textAppearance="@style/ChipTextAppearance"
 app:chipBackgroundColor="@color/colorAccent"
 app:chipIcon="@drawable/ic_call_white_24dp"
 app:closeIconEnabled="true"  <!--property for close icon if no need set to false. -->
 app:closeIconTint="@android:color/white" />
Then add style in style.xml
<style name="ChipTextAppearance" parent="TextAppearance.MaterialComponents.Chip">
    <item name="android:textColor">@android:color/white</item>
</style>
Step 2
Add AppCompactEditText
 <android.support.v7.widget.AppCompatEditText
    android:id="@+id/phone"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_marginEnd="8dp"
    android:layout_marginLeft="8dp"
    android:layout_marginRight="8dp"
    android:layout_marginStart="8dp"
    android:layout_marginTop="8dp"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toBottomOf="@+id/tvt_Contact" />
Step 3
java code
private int SpannedLength = 0,chipLength = 4;
 AppCompatEditText Phone = findViewById(R.id.phone);
 Phone.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
        }
        @Override
        public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
            if (charSequence.length() == SpannedLength - chipLength)
            {
                SpannedLength = charSequence.length();
            }
        }
        @Override
        public void afterTextChanged(Editable editable) {
            if(editable.length() - SpannedLength == chipLength) {
                ChipDrawable chip = ChipDrawable.createFromResource(getContext(), R.xml.chip);
                chip.setChipText(editable.subSequence(SpannedLength,editable.length()));
                chip.setBounds(0, 0, chip.getIntrinsicWidth(), chip.getIntrinsicHeight());
                ImageSpan span = new ImageSpan(chip);
                editable.setSpan(span, SpannedLength, editable.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
                SpannedLength = editable.length();
            }
        }
    });
@Override
public int getSize(@NonNull Paint paint, CharSequence text, int start, int end,
                   Paint.FontMetricsInt fontMetricsInt) {
    Drawable drawable = getDrawable();
    Rect rect = drawable.getBounds();
    if (fontMetricsInt != null) {
        Paint.FontMetricsInt fmPaint = paint.getFontMetricsInt();
        int fontHeight = fmPaint.descent - fmPaint.ascent;
        int drHeight = rect.bottom - rect.top;
        int centerY = fmPaint.ascent + fontHeight / 2;
        fontMetricsInt.ascent = centerY - drHeight / 2;
        fontMetricsInt.top = fontMetricsInt.ascent;
        fontMetricsInt.bottom = centerY + drHeight / 2;
        fontMetricsInt.descent = fontMetricsInt.bottom;
    }
    return rect.right;
}
@Override
public void draw(@NonNull Canvas canvas, CharSequence text, int start, int end,
                 float x, int top, int y, int bottom, @NonNull Paint paint) {
    Drawable drawable = getDrawable();
    canvas.save();
    Paint.FontMetricsInt fmPaint = paint.getFontMetricsInt();
    int fontHeight = fmPaint.descent - fmPaint.ascent;
    int centerY = y + fmPaint.descent - fontHeight / 2;
    int transY = centerY - (drawable.getBounds().bottom - drawable.getBounds().top) / 2;
    canvas.translate(x, transY);
    drawable.draw(canvas);
    canvas.restore();
}
}
And change your image span class like below
VerticalImageSpan span = new VerticalImageSpan(chip);
