建立MarqueeTextView类继承TextView

public class MarqueeTextView extends TextView {    public MarqueeTextView(Context context) {        super(context);    }    public MarqueeTextView(Context context, AttributeSet attrs) {        super(context, attrs);    }    public MarqueeTextView(Context context, AttributeSet attrs, int defStyleAttr) {        super(context, attrs, defStyleAttr);    }    public boolean isFocused() {        return true;    }}

控件代码必须实现的两个属性

<com.yun.duan.baseadpter_two.MarqueeTextView    android:ellipsize="marquee"    android:singleLine="true"
