How can I change the color of a part of a TextView

Question

text = text + CepVizyon.getPhoneCode() + "\n\n"
            + getText(R.string.currentversion) + CepVizyon.getLicenseText();
    activationText.setText(text);   
myTextView.setText(text);

I want to change color for CepVizyon.getPhoneCode()'s string. How can I do this?

Answer 1

I did as andy boot said, but i had a clickable span as well, and it didn't work because the order the setSpans were called. So you have to first call the spannable.setSpan(clickableSpanand... then the spannable.setSpan(new ForegroundColorSpan... to get the color in the TextView

Answer 2

It is good for me!

            Spannable spannable = new SpannableString("ABC In-Network DEF");
            String str = spannable.toString();
            iStart = str.indexOf("In-Network");
            iEnd = iStart + 10;/*10 characters = in-network. */

            SpannableString ssText = new SpannableString(spannable);
            ClickableSpan clickableSpan = new ClickableSpan() {
                @Override
                public void onClick(View widget) {
                    //your code at here.
                }

                @Override
                public void updateDrawState(TextPaint ds) {
                    super.updateDrawState(ds);
                    ds.setUnderlineText(true);
                    ds.setColor(getResources().getColor(R.color.green));
                }
            };
            ssText.setSpan(clickableSpan, iStart, iEnd, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
            mTextView.setText(ssText);
            mTextView.setMovementMethod(LinkMovementMethod.getInstance());
            mTextView.setHighlightColor(Color.TRANSPARENT);
            mTextView.setEnabled(true);

Here's a colorize function based on andyboot's answer:

 /**
 * Colorize a specific substring in a string for TextView. Use it like this: <pre>
 * textView.setText(
 *     Strings.colorized("The some words are black some are the default.","black", Color.BLACK),
 *     TextView.BufferType.SPANNABLE
 * );
 * </pre>
 * @param text Text that contains a substring to colorize
 * @param word The substring to colorize
 * @param argb The color
 * @return the Spannable for TextView's consumption
 */
public static Spannable colorized(final String text, final String word, final int argb) {
    final Spannable spannable = new SpannableString(text);
    int substringStart=0;
    int start;
    while((start=text.indexOf(word,substringStart))>=0){
        spannable.setSpan(
                new ForegroundColorSpan(argb),start,start+word.length(),
                Spannable.SPAN_EXCLUSIVE_EXCLUSIVE
        );
        substringStart = start+word.length();
    }
    return spannable;
}

If you have static text that needs color, you can add it without any code via the strings file:

<string name="already_have_an_account">Already have an account? <font color='#01C6DB'>Login</font></string>

then

<TextView
    android:layout_width="wrap_content"
    android:layout_height="64dp"
    android:text="@string/already_have_an_account"/>

result

not sure which api versions this works on, but doesnt work for api 19 that ive tested so far, so probably only some of the most recent api versions support this

edit: as @hairraisin mentioned in the comments, try using fgcolor instead of color for the font color, then it should work for lower api levels, but need more testing to be sure

Answer 5

With regards to Maneesh's answer, this will work but you need to add and escape the quotes for the color attribute.

myTextView.setText(Html.fromHtml(text + "<font color=\"#FFFFFF\">" + CepVizyon.getPhoneCode() + "</font><br><br>"
            + getText(R.string.currentversion) + CepVizyon.getLicenseText()));

Answer 6

Spannable is more flexible:

String text2 = text + CepVizyon.getPhoneCode() + "\n\n"
            + getText(R.string.currentversion) + CepVizyon.getLicenseText();

Spannable spannable = new SpannableString(text2);

spannable.setSpan(new ForegroundColorSpan(Color.WHITE), text.length(), (text + CepVizyon.getPhoneCode()).length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

myTextView.setText(spannable, TextView.BufferType.SPANNABLE);
