Is it possible to have a textview
to have different color for every word? Or even every letter? I tried extending textview
and creating it but howe
The SpannableString
class allows you to easily format certain pieces (spans) of a string one way and other pieces another by applying extensions of CharacterStyle (i.e. ForegroundColorSpan
) via the setSpan
method.
You can try This:
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.main);
richTextView = (TextView)findViewById(R.id.rich_text);
// this is the text we'll be operating on
SpannableString text = new SpannableString("Lorem ipsum dolor sit amet");
// make "Lorem" (characters 0 to 5) red
text.setSpan(new ForegroundColorSpan(Color.RED), 0, 5, 0);
// make "ipsum" (characters 6 to 11) one and a half time bigger than the textbox
text.setSpan(new RelativeSizeSpan(1.5f), 6, 11, 0);
// make "dolor" (characters 12 to 17) display a toast message when touched
final Context context = this;
ClickableSpan clickableSpan = new ClickableSpan() {
@Override
public void onClick(View view) {
Toast.makeText(context, "dolor", Toast.LENGTH_LONG).show();
}
};
text.setSpan(clickableSpan, 12, 17, 0);
// make "sit" (characters 18 to 21) struck through
text.setSpan(new StrikethroughSpan(), 18, 21, 0);
// make "amet" (characters 22 to 26) twice as big, green and a link to this site.
// it's important to set the color after the URLSpan or the standard
// link color will override it.
text.setSpan(new RelativeSizeSpan(2f), 22, 26, 0);
text.setSpan(new URLSpan("http://www.chrisumbel.com"), 22, 26, 0);
text.setSpan(new ForegroundColorSpan(Color.GREEN), 22, 26, 0);
// make our ClickableSpans and URLSpans work
richTextView.setMovementMethod(LinkMovementMethod.getInstance());
// shove our styled text into the TextView
richTextView.setText(text, BufferType.SPANNABLE);
}
The result will look like this:
