Question

I’m new to android and I’m trying to replace a character from bold style at a specific character in a arraylist string. What I’m doing is:

String myName = "76492";

This is my search string and i want to search this string in to the arraylist then i want to bold those character when getting on the arraylist.Arraylist string is 78758,3660,56798,6514,90679.

TextView txtf = (TextView)findViewById(R.id.textView4);
TextView txtS = (TextView) findViewById(R.id.textView5);                                    
TextView txtT = (TextView)findViewById(R.id.textView6);
TextView txt1 = (TextView) findViewById(R.id.textView9);
TextView txt2 = (TextView) findViewById(R.id.textView13);

String str= myName.replaceAll("6", "<b>6</b>");                                 
Spanned text = Html.fromHtml(str);
txtf.setText(text);
txtS.setText(text);
txtT.setText(text);
txt1.setText(text);
txt2.setText(text);

But this is replace all Textview String by the 76492 string with match charater bold style. 1879 search string this is replace old string but i donot want this type replace .iI want only specific position character change in bold style

Answer 1

<style name="boldText">
    <item name="android:textStyle">bold</item>

</style>

Paste this code snippet in your style.xml which is in valuse folder under layout.

txtf.setTextAppearance(this, R.style.boldText);

This line of code is for your text view appear as a bold.
