"Android" TextView set individual font styles

1 New Spannablestring ("Test" +xm+ "replacement of the current number will be sent from the mobile phone 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) method to obtain the TextView object byThe SetText () method dynamically assigns values, sets the single-line mode through the Android:singleline property, sets the overall color through the android:textcolor, and sets the automatic connection via the Android:autolink (none, ) of the type.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, there are two main types of ways to understand the format of text:first Category: HTML tag formatting textthe code is relatively simple, as follows:

　　

1 Importandroid.app.Activity; 2 ImportAndroid.os.Bundle; 3 Importandroid.text.Html; 4 ImportAndroid.widget.TextView; 5   6  Public classAndroidfroncolortestextendsActivity {7 @Override8      Public voidonCreate (Bundle savedinstancestate) {9         Super. OnCreate (savedinstancestate); Ten             One Setcontentview (R.layout.main);  A             -TextView Htmlformatetextview =(TextView) Findviewbyid (R.id.testtextview);  -             theString Source = "This is just a test, test <u> underline </u>, <i> italic word </i>, <font color= ' red ' > Red Word </font> The format ";  -      - Htmlformatetextview.settext (html.fromhtml (source));  -     }    +}

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).
