第一步，导入水果列表的代码。然后打开Fruit.java,添加变量：private String text;和private String time;分别的评论部分和显示时间的部分。添加Source-Generate Constructor using Fields,确定；再添加Getter、Setter方法。
第二步，这个时候系统会报错，打开MainActivity.java，修改initFruits()这个方法，Fruit apple = new Fruit(“潇湘夜雨”, R.drawable.p1,”今天好高兴啊！”,”1分钟前”);下边的也类似。
第三步，打开FruitAdapter.java，修改 getView这个方法。添加TextView textView=(TextView)view.findViewById(R.id.textView);
TextView textView2=(TextView)view.findViewById(R.id.textView2);再添加textView.setText(fruit.getText());
textView2.setText(fruit.getTime());
第四步，自定义标题栏。
1.在res/value下建立mytitlebar.xml文件
MainActivity.java
