How to set the selected text background color of TextView

Hello I am working on demo application where I need to set the yellow background color of selected text in a string.

For ex :

String str = "Na Adam ne ne yere Hawa: Na Adam xwoo xbabarima";

I want to set the white background color of all words except Adam. I need to set the background color of Adam word to yellow.

Thanks in advance.

This formatting would be suitable for JLabel:

JLabel label = new JLabel("<html>Na <font bgcolor='yellow'>Adam</font> ne ne yere Hawa: Na <font bgcolor='yellow'>Adam</font> xwoo xbabarima</html>");

Use the following code:

        String str = "Na Adam ne ne yere Hawa: Na Adam xwoo xbabarima";
        String stringToColor = "Adam"; 
        int ofe = str.indexOf(stringToColor,0);   
        Spannable WordtoSpan = new SpannableString(str);

for(int ofs=0;ofs<str.length() && ofe!=-1;ofs=ofe+1)
{       


      ofe = str.indexOf(stringToColor,ofs);   
          if(ofe == -1)
              break;
          else
              {                       

              WordtoSpan.setSpan(new BackgroundColorSpan(Color.YELLOW), ofe, ofe+stringToColor.length(),Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
              textView.setText(WordtoSpan, TextView.BufferType.SPANNABLE);
              }


}

You can use some html:

String adam = "<font color=#FFFF00>Adam</font>";
String str = "Na Adam ne ne yere Hawa: Na Adam xwoo xbabarima";
String newString = str.replaceAll("Adam", adam);
t.setText(Html.fromHtml(newString));

you can format the text as HTML such as:

   String htmlText =  "<font color=#000000>Na </font> <font color=#00FF00>Adam </font> <font color=#000000>ne ne yere Hawa: Na </font> <font color=#00FF00>Adam </font> <font color=#000000>xwoo xbabarima</font>"

    tView.setText(Html.fromHtml(htmlText))

In order to make it more dynamic you can add some regular expression functionality for identifying ur keywords which should be of a different color and create the HTML text

Look at this question here on setting the color of a TextView.

You can use

textView1.setTextColor(getResources().getColor(R.color.mycolor))

or

textview1.setBackgroundColor(Color.parseColor("#ffffff"));

or

textview1.setBackgroundColor(Color.RED);

or

textView1.setBackgroundColor(R.color.black);

You should look into the JEditorPane class, it allows you to do things like these easily:

JEditorPane editorPane = new JEditorPane("text/html","<font color=\"red\">this will be red</font><font color=\"blue\">, and this will be blue</font>");
