效果演示

安装教程

1.在项目根目录下的build.gradle文件中，

allprojects {
   repositories {
       maven {
           url 'https://s01.oss.sonatype.org/content/repositories/releases/'
       }
   }
}1.

2.在entry模块的build.gradle文件中，

dependencies {
   implementation('com.gitee.chinasoft_ohos:materialList:3.2.3')
   ......  
}1.
2.

在sdk6，DevEco Studio2.2 Beta1下项目可直接运行如无法运行，删除项目.gradle,.idea,build,gradle,build.gradle文件，并依据自己的版本创建新项目，将新项目的对应文件复制到根目录下

使用说明

MaterialList视图基于ListContainer。它的作用就像一个普通的列表视图，但是提供了与卡片交互的选项。它可以在单个或多个列表中显示卡片。

步骤1 在布局中声明MaterialListView:

<DependentLayout
    xmlns:ohos="http://schemas.huawei.com/res/ohos"
    xmlns:tools="http://schemas.huawei.com/tools"
    ohos:height="match_parent"
    ohos:width="match_parent"
    ohos:background_element="$color:main_background"
    >

    <com.dexafree.materialList.view.MaterialListView
        ohos:id="$+id:material_listview"
        ohos:height="match_parent"
        ohos:width="match_parent"
        ohos:below="$id:drLayout"/>

</DependentLayout>1.

还有一些附加属性用于定义MaterialListView的列计数，所以你需要：

xmlns:hap="http://schemas.huawei.com/apk/res/ohos"1.

您可以使用column_count属性在纵向和横向模式下使用固定列计数。

hap:column_count="1"1.

或者可以使用column_count_portrait和column_count_landscape属性。

hap:column_count_portrait="1"

hap:column_count_landscape="2"1.

步骤2 在代码中找到MaterialListView

MaterialListView mListView = (MaterialListView) findComponentById(ResourceTable.Id_material_listview);1.

步骤3 将Card添加到MaterialListView

Card card = new Card.Builder(this)
                            .setTag("BASIC_IMAGE_BUTTONS_CARD")
                            .withProvider(new CardProvider())
                            .setTitle("I'm new")
                            .setDescription("I've been generated on runtime!")
                            .setDrawable(ResourceTable.Media_dog)
                            .endConfig()
                            .build()

mListView.getItemProvider().add(card);1.
2.

4.
5.
6.
7.
8.
9.
10.

还有一些Card可能会在内容和按钮之间显示分隔符:

provider.setDividerVisible(true);1.

点击Card 您可以添加点击事件监听

mListView.addOnItemTouchListener(new RecyclerItemClickListener.OnItemClickListener() {
            @Override
            public void onItemClick(Card card, int position) {
                LogUtil.debug("CARD_TYPE", "" + card.getTag());
            }

            @Override
            public void onItemLongClick(Card card, int position) {
                LogUtil.debug("LONG_CLICK", "" + card.getTag());
            }
        });1.

同时检查Recovering data from the cards部分，以便能够恢复卡的内容

移除Card 我一直喜欢的一个操作就是SwipeToDismiss手势。 MaterialList提供了这个功能，为了设置对dismissing操作的回调，只需创建OnDismissCallback：

mListView.setOnDismissCallback(new OnDismissCallback() {
    @Override
    public void onDismiss(Card card, int position) {
        // Do whatever you want here
    }
});1.

您还可以通过调用“card.setDismissible（true）”来配置此Card是否可被移除。

动画 MaterialList可调用createAnimatorProperty创建任何property动画
