我使用带有RecyclerView的CarViews并且它在加载时看起来很好但是当滚动列表时,CardViews之间的间隙增加,并且一次只显示视图中的一张卡。
这是我的CardView.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto">
<android.support.v7.widget.CardView
android:id="@+id/conversationCard"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="16dp">
<TextView
android:id="@+id/sender"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:id="@+id/abstractConvo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="35dp"/>
</RelativeLayout>
</android.support.v7.widget.CardView>
</LinearLayout>
以下是我使用该视图的方式
public class ConversationsListAdapter extends RecyclerView.Adapter<ConversationsListAdapter.ConversationsListViewHolder> {
List<Conversation> conversationList;
public ConversationsListAdapter(List<Conversation> conversationList) {
this.conversationList = conversationList;
}
@Override
public int getItemCount() {
return conversationList.size();
}
@Override
public ConversationsListViewHolder onCreateViewHolder(ViewGroup viewGroup, int viewType) {
View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.conversation_card, viewGroup, false);
ConversationsListViewHolder listViewHolder = new ConversationsListViewHolder(view);
return listViewHolder;
}
@Override
public void onBindViewHolder(ConversationsListViewHolder holder, int position) {
holder.sender.setText(conversationList.get(position).getSenderPhNo());
holder.abstractConvo.setText(conversationList.get(position).getAbstractConvo());
}
public static class ConversationsListViewHolder extends RecyclerView.ViewHolder {
CardView cv;
TextView abstractConvo, sender;
public ConversationsListViewHolder(View itemView) {
super(itemView);
cv = (CardView) itemView.findViewById(R.id.conversationCard);
sender = (TextView) itemView.findViewById(R.id.sender);
abstractConvo = (TextView) itemView.findViewById(R.id.abstractConvo);
}
}
}
滚动后
提前致谢。

根布局使用wrap_content
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
xmlns:app="http://schemas.android.com/apk/res-auto">
