推荐答案

做到这一点的最佳方法是使用带有垂直LinearLayoutManager的RecyclerView(与ListView相同，但效果更好)性能)和CardView中的固定大小.您的CardView的xml如下所示:

The best way to do this is using a RecyclerView with a vertical LinearLayoutManager (which will look the the same as a ListView but with better performance) and a fixed size inside your CardView. The xml for your CardView will look something like this:

<android.support.v7.widget.CardView 
    android:layout_width="match_parent"
    android:layout_height="wrap_content" >

    <android.support.v7.widget.RecyclerView
        android:id="@+id/recyclerview"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

</android.support.v7.widget.CardView>

，然后以编程方式将RecyclerView上的固定大小设置为true，设置LayoutManager并创建一个自定义RecyclerView.Adapter来填充RecyclerView的行:

and then programmatically set fixed size on your RecyclerView to true, set the LayoutManager and create a custom RecyclerView.Adapter to fill the RecyclerView's rows:

RecyclerView recyclerView = parentView.findViewById(R.id.recyclerview);
recyclerView.setHasFixedSize(true);

LinearLayoutManager layoutManager = new LinearLayoutManager(context, LinearLayoutManager.VERTICAL, false);
recyclerView.setLayoutManager(layoutManager);

MyCustomAdapter adapter = new MyCustomAdapter(context, dataSet);
recyclerView.setAdapter(adapter);
