Android achieves the running horse light effect (more than two running horse lights can be implemented), android running horse lights
This article uses the MarqueeTextView inherited from TextView to achieve the effect of the running horse. The reason is that the effect of the marquee is that the TextView has focus to run. Sometimes, it takes a little time to get the focus of TextView, resulting in waiting for a period of time to see the effect of running the horse. In addition, by default, only one TextView is in the focused state, and when there are no less than two lawn lights on the page, TextView is hard to implement.

MarqueeTextView class code:

public class MarqueeTextView extends TextView{public MarqueeTextView(Context context, AttributeSet attrs) {super(context, attrs);// TODO Auto-generated constructor stub}@Overrideprotected void onFocusChanged(boolean focused, int direction,Rect previouslyFocusedRect) {// TODO Auto-generated method stubsuper.onFocusChanged(focused, direction, previouslyFocusedRect);}@Overridepublic void onWindowFocusChanged(boolean hasWindowFocus) {// TODO Auto-generated method stubif(hasWindowFocus) super.onWindowFocusChanged(hasWindowFocus);}@Override@ExportedProperty(category = "focus")public boolean isFocused() {return true;}}

Duplicate names
Simple Method: Rename
Copy the code again, and change the names of all the demos, demo1, demo2, Marquee, and MyMar copied. For example, add two to all the demos, such as demo22.
Rename the demo and demo1 of the first 2nd runners-up lamps, which is the same as the name changed above.
