3.31TextView跑步灯属性，及防止失效方法

1. <TextView  
2.                         android:id="@+id/textview1"  
3.                         android:layout_width="200dp"  
4.                         android:layout_height="wrap_content"  
5.                         android:layout_centerVertical="true"  
6.                         android:layout_toRightOf="@id/main_has_connected_textView"  
7.                         android:text="TextView"  
8.                         android:singleLine="true"  
9.                         android:ellipsize="marquee"  
10.                         android:focusable="true"  
11.                         android:marqueeRepeatLimit="marquee_forever"  
12.                         android:focusableInTouchMode="true"  
13.                         android:scrollHorizontally="true"  
14.                         android:textSize="22sp" />  

如果运行没有效果，是因为焦点丢失，解决方案：

public class FlowTextView extends TextView {
    
    public FlowTextView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }


    public FlowTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }


    public FlowTextView(Context context) {
        super(context);
    }


    @Override
    public boolean isFocused() {
        return true;
    }


}
