public class MarqueeTextView extends TextView {

@Override  

    protected void onFocusChanged(boolean focused, int direction, Rect previouslyFocusedRect) {  

        if(focused)  

            super.onFocusChanged(focused, direction, previouslyFocusedRect);  

    }  

    @Override  

    public void onWindowFocusChanged(boolean focused) {  

        if(focused)  

            super.onWindowFocusChanged(focused);  

    }  

    @Override  

    public boolean isFocused() {  

        return true;  

    }  

}

           android:singleLine="true"

            android:focusable="true"

            android:focusableInTouchMode="true"

            android:ellipsize="marquee"

            android:scrollHorizontally="true"

            android:marqueeRepeatLimit="marquee_forever"

这里解决了：1、下拉状态栏到半截不松开时和失去焦点时显示"......"的问题

                     2、失去焦点不滚动问题。

TextView不用获取焦点也能实现跑马灯
