用的的布局文件general_order_item
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"

</RelativeLayout>使用MenuLinearLayout

mBindingView.llMenu.addTitleImage(title,img,count);
mBindingView.llMenu.setItemListener(new MenuLinearLayout.IItemListener() {
@Override
public void onItemClick(String name, int pos) {
CustomToast.showShort(name + " pos = " + pos);
}
});attrs下
<declare-styleable name="MenuLinearLayout">
<attr name="weight_sum" format="integer"/>
<attr name="menu_item_height" format="dimension"/>
<attr name="item_child_textColor" format="color"/>
<attr name="item_child_textSize" format="dimension"/>
</declare-styleable>最终效果
利用MenuLinearlayout实现其他功能的效果
文章中的包，以及判空工具类，资源文件等需要手动修改一下
