分析:这个错误是传入某个参数的格式问题
CheckableButton button = new CheckableButton(this);
DataStore dataStore = new DataStore();
dataStore.GoodsInfo.add("商品");
dataStore.ChannelCom.add("推荐频道");
button.setText(dataStore.GoodsInfo.get(0));
flowLayout1.addView(button);//5
button.setText(dataStore.ChannelCom.get(0));
flowLayout2.addView(button);//7
注意第5和第7行,先后向容器flowLayout1和容器flowLayout2中添加同一个控件button
造成了冲突而报错
