Example of setting TextView/Button revolving * (Marquee) effect in android

In Android's ApiDemo, there is a Button's revolving * effect, but if it is a TextView, there is still a little difference.
Define a revolving * (Marquee), mainly in Project/res/layout/

Copy the codeThe code is as follows:

 
<SPAN style="COLOR: #993300"><TextView 
android:layout_width="40px" 
android:layout_height="wrap_content" 
android:text="Test marquee for TextView" 
android:layout_gravity="center" 
android:ellipsize="marquee" 
android:singleLine="true" 
android:focusable="true" 
android:marqueeRepeatLimit="marquee_forever" 
android:focusableInTouchMode="true" 
android:scrollHorizontally="true" 
/></SPAN> 

Key points:
(1) The length set by layout_width must be shorter than the actual length of text, that is, the text displays incomplete text will have a revolving * effect (2) ellipsize means using the revolving * marquee
(3) singleLine means single line display
(4) marqueeRepeatLimit indicates the number of times the revolving light is displayed: marquee_forever-unlimited uninterrupted display

Copy the codeThe code is as follows:

 
<SPAN style="COLOR: #993300"><Button 
android: 
android:layout_width="320px" 
android:layout_height="wrap_content" 
android:text="@string/textMarquee" 
android:singleLine="true" 
android:focusable="true" 
android:selectAllOnFocus="true" 
android:ellipsize="marquee" 
android:marqueeRepeatLimit="marquee_forever" 
/></SPAN> 

where @string/textMarquee is a string defined by /res/value/
