Set color of TextView span in Android
Another answer would be very similar, but wouldn't need to set the text of the TextView twice
TextView TV = (TextView)findViewById(R.id.mytextview01);Spannable wordtoSpan = new SpannableString("I know just how to whisper, And I know just how to cry,I know just where to find the answers"); wordtoSpan.setSpan(new ForegroundColorSpan(Color.BLUE), 15, 30, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);TV.setText(wordtoSpan);
Here is a little help function. Great for when you have multiple languages!
private void setColor(TextView view, String fulltext, String subtext, int color) { view.setText(fulltext, TextView.BufferType.SPANNABLE); Spannable str = (Spannable) view.getText(); int i = fulltext.indexOf(subtext); str.setSpan(new ForegroundColorSpan(color), i, i + subtext.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);}
I always find visual examples helpful when trying to understand a new concept.
Background Color
SpannableString spannableString = new SpannableString("Hello World!");BackgroundColorSpan backgroundSpan = new BackgroundColorSpan(Color.YELLOW);spannableString.setSpan(backgroundSpan, 0, spannableString.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);textView.setText(spannableString);Foreground Color
SpannableString spannableString = new SpannableString("Hello World!");ForegroundColorSpan foregroundSpan = new ForegroundColorSpan(Color.RED);spannableString.setSpan(foregroundSpan, 0, spannableString.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);textView.setText(spannableString);Combination
SpannableString spannableString = new SpannableString("Hello World!");ForegroundColorSpan foregroundSpan = new ForegroundColorSpan(Color.RED);BackgroundColorSpan backgroundSpan = new BackgroundColorSpan(Color.YELLOW);spannableString.setSpan(foregroundSpan, 0, 8, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);spannableString.setSpan(backgroundSpan, 3, spannableString.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);textView.setText(spannableString);
