+A {@link android.text.Spannable} is a text object that you can style with
+typeface properties such as color and font weight. You use
+{@link android.text.SpannableStringBuilder} to build
+your text and then apply styles defined in the {@link android.text.style}
+package to the text.

+ for (Object tag : tags) {
+ text.setSpan(tag, 0, 0, Spannable.SPAN_MARK_MARK);
+ }
+}
+
+/**
+ * "Closes" the specified tags on a Spannable by updating the spans to be
+ * endpoint-exclusive so that future text appended to the end will not take
+ * on the same styling. Do not call this method directly.

+ } else {
+ text.removeSpan(tag);
+ }
+ }
+}
+</pre>
+<p>
+The following <code>bold</code>, <code>italic</code>, and <code>color</code>
+methods show you how to call the helper methods to apply
+styles defined in the {@link android.text.style} package. You
+can create similar methods to do other types of text styling.
+</p>
+
+<pre style="pretty-print">
+/**
+ * Returns a CharSequence that applies boldface to the concatenation
+ * of the specified CharSequence objects.
+ */
+public static CharSequence bold(CharSequence... content) {
+ return apply(content, new StyleSpan(Typeface.BOLD));
+}
+
+/**
+ * Returns a CharSequence that applies italics to the concatenation
+ * of the specified CharSequence objects.
+ */
+public static CharSequence italic(CharSequence... content) {
+ return apply(content, new StyleSpan(Typeface.ITALIC));

+ * Returns a CharSequence that applies a foreground color to the
+ * concatenation of the specified CharSequence objects.
+ */
+public static CharSequence color(int color, CharSequence... content) {
+ return apply(content, new ForegroundColorSpan(color));
+}
+</pre>
+<p>
+Here's an example of how to chain these methods to create a character sequence
+with different types of styling applied to individual words:
+</p>
+
+<pre style="pretty-print">
+// Create an italic "hello, " a red "world",
+// and bold the entire sequence.
+CharSequence text = bold(italic(res.getString(R.string.hello)),
+ color(Color.RED, res.getString(R.string.world)));
