Is it possible to change the text color in a string to multiple colors in Java?

Question

What I mean is, is it possible to change the text "This text is blue" to the color blue in a single string? There must be a way...

<TextView     android:gravity="left"     android:padding="3dip"     android:text="This text is white. This text is blue."     android:textColor="#ffffff"     android:textSize="22dp"/> 

Answer 1

Yes, its possible. For this you need to use SpannableString and ForegroundColorSpan.

This should look something like this:

SpannableStringBuilder builder = new SpannableStringBuilder();  String red = "this is red"; SpannableString redSpannable= new SpannableString(red); redSpannable.setSpan(new ForegroundColorSpan(Color.RED), 0, red.length(), 0); builder.append(redSpannable);  String white = "this is white"; SpannableString whiteSpannable= new SpannableString(white); whiteSpannable.setSpan(new ForegroundColorSpan(Color.WHITE), 0, white.length(), 0); builder.append(whiteSpannable);  String blue = "this is blue"; SpannableString blueSpannable = new SpannableString(blue); blueSpannable.setSpan(new ForegroundColorSpan(Color.BLUE), 0, blue.length(), 0); builder.append(blueSpannable);  mTextView.setText(builder, BufferType.SPANNABLE);

A simple way to do it is to use HTML and set the text to the TextView programmatically.

String text = "This text is white. <font color=\"blue\">This text is blue.</font>"; textView.setText(Html.fromHtml(text), BufferType.SPANNABLE);
