Android TextView text through spannablestring to set hyperlinks, colors, fonts, etc.

In Android, TextView is the most common control we use to display text.

In general, the text in TextView is a style. So how do you set the font, size, color, style, and hyperlink properties for each part of the TextView text? Let's demonstrate this by spannablestring specific examples.

Res-layout-main.xml

1. <?xml version= "1.0" encoding= "Utf-8"?>

2. <linearlayout xmlns:android= "Http://schemas.android.com/apk/res/android"

3. android:layout_height= "Wrap_content" android:layout_width= "wrap_content" android:orientation= "Horizontal" >

4. <textview

5. Android:id= "@+id/mytextview"

6. Android:layout_width= "Fill_parent"

7. android:layout_height= "Wrap_content"

8. />

9. </LinearLayout>

Res-color-color.xml

Res-color-linkcolor.xml

View Plainprint?

1. <?xml version= "1.0" encoding= "Utf-8"?>

2. <selector xmlns:android= "Http://schemas.android.com/apk/res/android" >

3. <item android:state_pressed= "true"

4. Android:color= "#ffffff00"/> <!--pressed--

5. <item android:state_focused= "true"

6. Android:color= "#ff00ffff"/> <!--focused--

7. <item android:color= "#ff0ff000"/> <!--Default---

8. </selector>

86. Create a Spannablestring object

88. MSP = new spannablestring (font test font size half twice times foreground background color normal bold italic bold italic underline strikethrough x1x2 phone mail website sms MMS map x Axis synthesis ");

90.
