Align top two textviews with different font sizes

Question

Im using constraint layout and i want to achieve the following:

The app:layout_constraintBaseline_toBaselineOf attribute bottom aligns the two textviews, is there any way to top align the two? The regular app:layout_constraintTop_toTopOf is not working of course because of the size differences.

is it helpful? http://android-er.blogspot.in/2011/09/set-styling-text-on-textview.html — Aditya Vyas-Lakhan, Sep 18 '17 at 09:14
There is no code, its just two text views with attributes inside constraint layout. — Evgeni Roitburg, Sep 18 '17 at 09:15

So it seems there is no a convenient way of doing this and a custom view must be implemented. I've taken inspiration from here:

Try this .

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <TextView
        android:id="@+id/tv_unit"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="6dp"
        android:text="$"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintTop_toTopOf="parent"/>

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:gravity="top"
        android:text="120"
        android:textSize="40sp"
        android:textStyle="bold"
        app:layout_constraintLeft_toRightOf="@+id/tv_unit"
        app:layout_constraintTop_toTopOf="parent"/>

</android.support.constraint.ConstraintLayout>

Like this .

It's easy .And `ConstraintLayout` is similar to `RelativeLayout` . — KeLiuyue, Sep 18 '17 at 09:29
Its not a proper solution, you've just used a hardcoded margin to align both views. — Evgeni Roitburg, Sep 18 '17 at 10:29

try this you can use Html.fromHtml for this purpose

Html.fromHtml Returns displayable styled text from the provided HTML string.

yourTextview.setText(Html.fromHtml("<sup><small>$</small></sup>42"));

or try this use SpannableString

TextView textView = rootView.findViewById(R.id.tv);
SpannableStringBuilder sb = new SpannableStringBuilder("$42");
sb.setSpan(new SuperscriptSpan(), 0, 1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
textView.setText(sb, TextView.BufferType.SPANNABLE);

Not getting the desired effect – Evgeni Roitburg Sep 18 '17 at 10:49
No, the two texts are not exactly aligned. The dollar sign is higher than the number. – Evgeni Roitburg Sep 18 '17 at 10:58
@EvgeniRoitburg use **SpannableString** – AskNilesh Sep 18 '17 at 11:05

Do this way

String s = "$<sub>12 </sub>";
        textView.setText(Html.fromHtml(s)); // 12 will cropped 
// solution:
        s = "$<sub>12 </sub>\t  "; // add behind ending of sup tag the tabulator \t,
// but not char \t but only press to TAB key!!! in source code
        textView.setText(Html.fromHtml(s)); // 12 is visible correctly
