我正在尝试使用 Cardslib 创建一个带有自定义布局行的 RecyclerView，当我单击它们上的按钮时，这些行会展开。我按照自定义指南创建了自定义布局和自定义卡片类，卡片确实像这样正确显示，
但我不知道如何为这张卡片上的视图元素设置点击事件。
在 activity_main.xml 中，我有一个 CardRecyclerView：
<it.gmariotti.cardslib.library.recyclerview.view.CardRecyclerView
android:layout_width="match_parent"
android:layout_height="match_parent"
card:list_card_layout_resourceID="@layout/my_cardview_layout"
android:id="@+id/my_recyclerview"/>
my_cardview_layout.xml：
<it.gmariotti.cardslib.library.view.CardViewNative xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:card="http://schemas.android.com/apk/res-auto"
android:id="@+id/list_cardId"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="12dp"
android:layout_marginRight="12dp"
card:card_layout_resourceID="@layout/my_material_card_layout"
style="@style/card_external"
android:layout_marginTop="12dp" />
my_material_card_layout.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<it.gmariotti.cardslib.library.view.ForegroundLinearLayout
android:id="@+id/card_main_layout"
style="@style/card.native.main_layout_foreground"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ImageView
android:layout_width="match_parent"
android:layout_height="210dp"
android:id="@+id/mycard_image"
android:src="@drawable/sea"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="Title"
android:id="@+id/mycard_title"
android:paddingTop="24dp"
android:paddingLeft="20dp"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceSmall"
android:text="Subtitle"
android:id="@+id/mycard_subtitle"
android:paddingLeft="20dp" />
<LinearLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="@dimen/actions_padding"
android:paddingLeft="@dimen/actions_padding_left"
android:paddingRight="@dimen/actions_padding_left">
<TextView
android:id="@+id/mycard_suppaction1"
android:text="SHARE"
android:background="?android:selectableItemBackground"
android:layout_width="wrap_content"
style="@style/card.native.actions"
android:layout_height="wrap_content"/>
<TextView
android:id="@+id/mycard_suppaction2"
android:text="LEARN MORE"
android:background="?android:selectableItemBackground"
android:layout_width="wrap_content"
style="@style/card.native.actions"
android:layout_height="wrap_content"/>
</LinearLayout>
</it.gmariotti.cardslib.library.view.ForegroundLinearLayout>
<FrameLayout
android:id="@+id/card_content_expand_layout"
style="@style/card.native.main_contentExpand"
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
</FrameLayout>
我的主要活动：
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ArrayList<Card> cards = new ArrayList<Card>();
//CardViewNative cardView = (CardViewNative) findViewById(R.id.myMaterialCardView);
for(int i = 0; i<3; i++) {
MyMaterialCard card = new MyMaterialCard(this);
CardExpand expand = new CardExpand(getApplicationContext());
//Set inner title in Expand Area
expand.setTitle(" Hidden content");
card.addCardExpand(expand);
card.setId("" + i);
cards.add(card);
}
CardArrayRecyclerViewAdapter mCardArrayAdapter = new CardArrayRecyclerViewAdapter(this, cards);
//Staggered grid view
CardRecyclerView mRecyclerView = (CardRecyclerView) this.findViewById(R.id.my_recyclerview);
mRecyclerView.setHasFixedSize(false);
mRecyclerView.setLayoutManager(new LinearLayoutManager(this));
//Set the empty view
if (mRecyclerView != null) {
mRecyclerView.setAdapter(mCardArrayAdapter);
}
}
我的自定义卡类：
public class MyMaterialCard extends Card {
ImageView mImage;
TextView mTitle;
TextView mSubtitle;
TextView mActionButton1;
TextView mActionButton2;
public MyMaterialCard(Context context) {
super(context, R.layout.my_cardview_layout);
}
public MyMaterialCard(Context context, int innerLayout) {
super(context, innerLayout);
}
@Override
public void setupInnerViewElements(ViewGroup parent, View view) {
mImage = (ImageView) view.findViewById(R.id.mycard_image);
mTitle = (TextView) view.findViewById(R.id.mycard_title);
mSubtitle = (TextView) view.findViewById(R.id.mycard_subtitle);
mActionButton1 = (TextView) view.findViewById(R.id.mycard_suppaction1);
mActionButton2 = (TextView) view.findViewById(R.id.mycard_suppaction2);
mActionButton1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(getContext(), "action 1", Toast.LENGTH_SHORT).show();
}
});
ViewToClickToExpand viewToClickToExpand =
ViewToClickToExpand.builder()
.setupView(mActionButton2);
setViewToClickToExpand(viewToClickToExpand);
}}
我认为问题可能是 my_cardview_layout.xml，但是，如果我card:list_card_layout_resourceID="@layout/my_material_card_layout"
在 recyclerview 中设置并且
public MyMaterialCard(Context context) {
super(context, R.layout.my_material_card_layout);}
它们不会显示为卡片：
已经为此工作了 2 天，仍然无法让这些按钮工作（尝试使用 Cardslib 材料卡，但添加扩展时，没有任何反应）。非常感谢任何帮助，谢谢！
