android - 从数组列表中设置抽屉项目并在 MaterialDrawer 中单击

Question

在我的 android 应用程序中，我使用 greeDAO ORM for sqlite。所以我检索了我的类别列表:

 List<ArticleCategory> categories = articleCategoryDao.queryBuilder().list(); 

每个 ArcticleCategory 对象都有 name 和 description 属性，所以我可以将它们用于抽屉项目的名称和描述。我的问题是如何将此列表添加到 myDrawer 项目和如何管理他们的点击事件。这是我的抽屉代码:

    Drawer myDrawer = new DrawerBuilder().withActivity(this).withToolbar(toolbar)
            .addDrawerItems(
                    new PrimaryDrawerItem().withName("Home").withIcon(GoogleMaterial.Icon.gmd_import_contacts).withIconColor(Color.BLACK)
            )
            .withOnDrawerItemClickListener(new Drawer.OnDrawerItemClickListener() {
                @Override
                public boolean onItemClick(View view, int position, IDrawerItem drawerItem) {

                    return false;
                }
            })
            .withAccountHeader(navigationHeader)
            .withDrawerGravity(GravityCompat.START)
            .build();

请记住，我有一些手动静态项目和抽屉项目，还有一些来自数据库的动态项目，因此在这种情况下点击事件对我来说非常重要。

Answer 1

要将 Categories 添加到抽屉中，您首先必须创建 DrawerItems，您可以通过遍历项目来完成此操作。

ArrayList<IDrawerItem> drawerItems = new ArrayList<>();
for(ArticleCategory category : categories) {
   drawerItems.add(new PrimaryDrawerItem().withName(category.getName()).withDescription(category.getDescription()));
   //if you have a id you can also do: .withIdentifier(category.getIdentifier());
   //depending on what you need to identify or to do the logic on click on one of those items you can also set a tag on the item: .withTag(category);
}

创建项目后，将它们添加到 DrawerBuilder

drawerBuilder.withDrawerItems(drawerItems);

现在创建抽屉后，您必须为 Listener 编写逻辑。您的“静态”DrawerItem 应该定义一个标识符，这样当其中一个被点击时您可以直接使用react

.withOnDrawerItemClickListener(new Drawer.OnDrawerItemClickListener() {
  @Override
  public boolean onItemClick(View view, int position, IDrawerItem drawerItem) {
      if (drawerItem != null) {
          Intent intent = null;
          if (drawerItem.getIdentifier() == 1) {
              //static item with ID 1
          } else if (drawerItem.getIdentifier() == 2) {
              //static item with ID 2
          } else {
              //if none of your static items were clicked handle the logic for the categories. 
              //now you have the drawerItem which were created from a category
              //you can identify them by identifier, their tag, or name. Depends on what you need to do your logic here

          }
      }

      return false;
  }
})
