1：自定义一个控件继承TextView,重写isFocused方法，返回值为true;

package com.example.helloandroid;import android.R.bool;import android.content.Context;import android.util.AttributeSet;import android.view.ViewDebug.ExportedProperty;import android.widget.TextView;public class MarqueeText extends TextView {    public MarqueeText(Context context) {        super(context);        // TODO Auto-generated constructor stub    }    public MarqueeText(Context context, AttributeSet attrs, int defStyle) {        super(context, attrs, defStyle);        // TODO Auto-generated constructor stub    }    public MarqueeText(Context context, AttributeSet attrs) {        super(context, attrs);        // TODO Auto-generated constructor stub    }    @Override    @ExportedProperty(category = "focus")    public boolean isFocused() {        // TODO Auto-generated method stub        return true;    }}

2：给两个text空间添加属性，记得一定加上包名以及类名
