The text in Android textview uses spannablestring to set attributes such as hyperlinks, colors, and fonts.

In Android, textview is the most common control used to display text.

In general, the text in textview is a style. How can we set the font, size, color, style, hyperlink, and other attributes for each part of textview text? The following is an example of spannablestring.

Res-layout-main.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_height="wrap_content" android:layout_width="wrap_content" android:orientation="horizontal"><TextView  android:id="@+id/myTextView"    android:layout_width="fill_parent"     android:layout_height="wrap_content"     /></LinearLayout>

Res-color-color.xml

Res-color-linkcolor.xml

<?xml version="1.0" encoding="utf-8"?><selector  xmlns:android="http://schemas.android.com/apk/res/android">    <item android:state_pressed="true"          android:color="#ffffff00"/> <!-- pressed -->    <item android:state_focused="true"          android:color="#ff00ffff"/> <!-- focused -->    <item android:color="#ff0ff000"/> <!-- default --></selector>
