"Android" TextView set individual font styles

1 spannablestring MSP = new spannablestring ("Test" +xm+ "replacement of the current number will be sent from the phone with a regular text message to verify"); 2 Msp.setspan (New Foregroundcolorspan ( Color.Blue), 2, Xm.length () +2, spanned.span_exclusive_exclusive);

The textview:textview of the impression is the control used to display the text, which can be set in the layout file via the Android:text property, or through the context object's Findviewbyid (XXX) After the TextView object is obtained, the SetText () method is used to dynamically assign values, set the single-line mode through the Android:singleline property, and set the overall color through the Android:textcolor via Android: Autolink to set the type of automatic connection (none). Never thought about displaying text in a variety of ways in a TextView control. Textview further deepening: Textview can format its text. By querying the data, the way to understand the format of the text is divided into two main categories: the first Category: HTML tags Formatted text code is relatively simple, as follows:

　　

1 import android.app.Activity;    2 import Android.os.Bundle;    3 Import android.text.Html;    4 Import Android.widget.TextView;    5    6 public class Androidfroncolortest extends Activity {    7     @Override   8 public     void OnCreate (Bundle Savedinstancestate) {    9         super.oncreate (savedinstancestate);   Ten         Setcontentview (r.layout.main);         TextView Htmlformatetextview = (TextView) Findviewbyid (R.id.testtextview);         String Source = "This is just a test, test <u> underline </u>, <i> Italic </i>, <font color= ' red ' > Red word </font> format ";         Htmlformatetextview.settext (html.fromhtml (source));   19}  

The second class is formatted by spannablestring

When using Spannablestring objects, be aware that
The role of spanned.span_exclusive_exclusive, etc.:
Used to identify whether or not to use this effect when entering new characters before and after text in a span range. Spanned.span_exclusive_exclusive (not included), Spanned.span_inclusive_exclusive (previously included, not included), Spanned.span_ Exclusive_inclusive (not included in front, included later), Spanned.span_inclusive_inclusive (included before and after).
