SubscriptSpan and Superscript span example in Sketchware

SubscriptSpan example

The span that moves the position of the text baseline lower.

Note: Since the span affects the position of the text, if the text is on the last line of a TextView, it may appear cut.

Constructor:
SubscriptSpan()
Creates a SubscriptSpan.

This example shows use of SubscriptSpan in Sketchware.

1. In main.xml add a TextView textview1.

2. In MainActivity.java, create a new String mystring.

3. In onCreate of MainActivity.java:
a. Set the text of mystring to:
H2O = Water

b. Use an add source directly block to put following codes:
// Convert this String to a Spannable String ss.
SpannableString ss = new SpannableString(mystring);

// Add SubscriptSpan to 2 of H2O in above text.
ss.setSpan(new android.text.style.SubscriptSpan(), 1, 2, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);

// Display the Spannable String in TextView.
textview1.setText(ss);

4. Save and run the project. It will show result as in image below.



SuperscriptSpan example

The span that moves the position of the text baseline higher.

Note: Since the span affects the position of the text, if the text is on the first line of a TextView, it may appear cut. This can be avoided by decreasing the text size with an AbsoluteSizeSpan.

Constructor:
SuperscriptSpan()
Creates a SuperscriptSpan.

This example shows use of SuperscriptSpan in Sketchware.

1. In main.xml add a TextView textview1.

2. In MainActivity.java, create a new String mystring.

3. In onCreate of MainActivity.java:

We three are the 1st, 2nd and 3rd here.

b. Use an add source directly block to put following codes:
// Convert this String to a Spannable String ss.
SpannableString ss = new SpannableString(mystring);

// Add SuperscriptSpan to 'st' of 1st, 'nd' of 2nd and 'rd' of 3rd in above text.
ss.setSpan(new android.text.style.SuperscriptSpan(), 18, 20, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
ss.setSpan(new android.text.style.SuperscriptSpan(), 23, 25, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
ss.setSpan(new android.text.style.SuperscriptSpan(), 31, 33, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);

    Okay but let me rephrase the question ........... I made a (MoreBlock) called (add) which has 3 variables, the first is called (pos) and is (Number), the second is called (code) and it is (Boolean) and the third one is called (description) and it is (Boolean) ............ then I made a (MoreBlock) called (codes) which I added several blocks called ( add); in each one I put a value the pos I started from 0 and the rest increases one by one 0.1,2,3, ... in (code) they have texts and in (description) they have other texts and what I want to do is put buttons (Button) menu type, which when pressing the first call key 0 and key (code) of the block (codes) to get the text --GetText-- of (code) and with ( SetText) put it in an (EditText) but no matter how hard I try, I don't send you the project so that you understand it better https://1drv.ms/u/s!AjUQDCAtSdWgjRVFTM_FBBKGjRqP?e=KgHF6p

      I think you need a custom ListView. Create a Maplist. Add items (Map variables) to it. In each Map variable add key code and description with their values.
