Highlighting Text Color using Html.fromHtml() in Android?

Question

I am developing an application in which there will be a search screen where user can search for specific keywords and that keyword should be highlighted. I have found Html.f

Answer 1

font is deprecated use span instead Html.fromHtml("<span style=color:red>"+content+"</span>")

Answer 2

Using color value from xml resource:

int labelColor = getResources().getColor(R.color.label_color);
String сolorString = String.format("%X", labelColor).substring(2); // !!strip alpha value!!

Html.fromHtml(String.format("<font color=\"#%s\">text</font>", сolorString), TextView.BufferType.SPANNABLE); 

Answer 3

Or far simpler than dealing with Spannables manually, since you didn't say that you want the background highlighted, just the text:

String styledText = "This is <font color='red'>simple</font>.";
textView.setText(Html.fromHtml(styledText), TextView.BufferType.SPANNABLE);

Answer 4

First Convert your string into HTML then convert it into spannable. do as suggest the following codes.

 Spannable spannable = new SpannableString(Html.fromHtml(labelText));
                    
spannable.setSpan(new ForegroundColorSpan(Color.parseColor(color)), spannable.toString().indexOf("•"), spannable.toString().lastIndexOf("•") + 1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
            

Answer 5

To make part of your text underlined and colored

in your strings.xml

<string name="text_with_colored_underline">put the text here and &lt;u>&lt;font color="#your_hexa_color">the underlined colored part here&lt;font>&lt;u></string>

then in the activity

yourTextView.setText(Html.fromHtml(getString(R.string.text_with_colored_underline)));

and for clickable links:

<string name="text_with_link"><![CDATA[<p>text before link<a href=\"http://www.google.com\">title of link</a>.<p>]]></string>

and in your activity:

yourTextView.setText(Html.fromHtml(getString(R.string.text_with_link)));
yourTextView.setMovementMethod(LinkMovementMethod.getInstance());

Answer 6

This can be achieved using a Spannable String. You will need to import the following

import android.text.SpannableString; 
import android.text.style.BackgroundColorSpan; 
import android.text.style.StyleSpan;

And then you can change the background of the text using something like the following:

TextView text = (TextView) findViewById(R.id.text_login);
text.setText("");
text.append("Add all your funky text in here");
Spannable sText = (Spannable) text.getText();
sText.setSpan(new BackgroundColorSpan(Color.RED), 1, 4, 0);

Where this will highlight the charecters at pos 1 - 4 with a red color. Hope this helps!
