Matryoshka Text

This is a fork of a matryoshkaText library: https://github.com/quiqueqs/BabushkaText . I just added Click functionality and adding custom typefaces to parts of text.

MatryoshkaText is a custom TextView which lets you customize the styling of parts of your text via Spannables, but without the hassle of having to deal directly with Spannable themselves.

Create complex style structures for your text without having to add multiple TextViews to your view hierarchy.
Eliminate setSpan(Object what, int start, int end, int flags) calls by using more convenient methods such as .style(Typeface.BOLD), .superscript() and others.

What can I do with MatryoshkaText?

Examples of different styles. Each one is a single TextView.

Example

Generate the following style:

With the code below:

        MatryoshkaText matryoshka = (MatryoshkaText)findViewById(R.id.matryoshka_text);

        // Add the first piece "Central Park"
        matryoshka.addPiece(new MatryoshkaText.Piece.Builder("Central Park, NY\n")
                .textColor(Color.parseColor("#414141"))
                .build());

        // Add the second piece "1.2 mi"
        matryoshka.addPiece(new MatryoshkaText.Piece.Builder("1.2 mi ")
                .textColor(Color.parseColor("#0081E2"))
                .textSizeRelative(0.9f)
                .build());

        // Add the third piece "from here"
        matryoshka.addPiece(new MatryoshkaText.Piece.Builder("from here")
                .textColor(Color.parseColor("#969696"))
                .textSizeRelative(0.9f)
                .build());

        // Display the final, styled text
        matryoshka.display();

What kind of styles can I add?

Right now you can customize the style of your text by using the following methods, which internally get converted to the corresponding Spannables

MatryoshkaText Method	Internal Span
textSize	AbsoluteSizeSpan
textColor	ForegroundColorSpan
textSizeRelative	RelativeSizeSpan
backgroundColor	BackgroundColorSpan
style	StyleSpan
underline	UnderlineSpan
strike	StrikethroughSpan
superscript	SuperscriptSpan
subscript	SubscriptSpan
clickCallback	TouchableSpan
typeface	TypefaceSpan

What else can I do?

Once you've created and displayed your MatryoshkaText, you can modify the text contents of each Piece individually. For example, if we want to change the 1.2 mi from the above example into 1.9 km, we could do the following:

// grab the Piece at position 1
Piece piece = matryoshka.getPiece(1);

// modify it's text
piece.setText("1.9 km ");

// you must always call display after you alter a Piece's text
matryoshka.display();
