You can set the text as html:

txt.setText(Html.fromHtml("your <font color='#FF0000'>content</font>");

Use spans

Example:

{
   final SpannableStringBuilder sb = new SpannableStringBuilder("your text here");
   final ForegroundColorSpan fcs = new ForegroundColorSpan(Color.rgb(158, 158, 158)); 

   // Span to set text color to some RGB value
   final StyleSpan bss = new StyleSpan(android.graphics.Typeface.BOLD); 

   // Span to make text bold
   sb.setSpan(fcs, 0, 4, Spannable.SPAN_INCLUSIVE_INCLUSIVE); 

   // Set the text color for first 4 characters
   sb.setSpan(bss, 0, 4, Spannable.SPAN_INCLUSIVE_INCLUSIVE); 

   // make them also bold
   yourTextView.setText(sb);
}

Here is a solution specific to your case:

Update your code as follows:

JSONArray jArray= new JSONArray(result);
Spanned spannedStr = null;
for(int i=0; i<jArray.length();i++)
{
    JSONObject getjson = jArray.getJSONObject(i);

    spannedStr = (Spanned) TextUtils.concat(getColorString("Title:"), getjson.getString("tender_title"), "\n\n",
            getColorString("Tender id:"), getjson.getString("tender_title"), "\n\n",
            getColorString("Reference no:"), getjson.getString("tender_title"), "\n\n",
            getColorString("Quantity:"), getjson.getString("tender_title"));

}
TextView txt=(TextView) findViewById(R.id.textView1);
txt.setText(spannedStr);

Define a helper method in the same class and use it:

private Spanned getColorString(String str) {
    return Html.fromHtml("<font color='#FFFF00'>" + str + "</font>");
}

Sample output:

you can use Spanned also for that.

 Spanned sText=Html.fromHtml("<font color="#C3003">Title:</font> "  );

txt.setText(sText);

 Spannable WordtoSpan = new SpannableString(text);

 WordtoSpan.setSpan(new ForegroundColorSpan(Color.WHITE), text.length, (text +      
 nextString.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

 myTextView.setText(WordtoSpan);
