RecyclerView 中的 CardView 在进入查看时调整自身大小

Question

我制作了一个包含许多不同 CardView 的 RecyclerView。当 RecyclerView 第一次加载时，在回收站视图中可见的在屏幕上启动的卡片是正确的大小，但是当它们滚动到屏幕外时，下次它们回到屏幕上时，它们已被调整大小并且尺寸不正确。

LocationsListFragment：

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    View v = inflater.inflate(R.layout.fragment_locations_list, container, false);
    adapter = new LocationsAdapter(mParam1);

    RecyclerView recyclerView = (RecyclerView)v.findViewById(R.id.recycler_locations);
    recyclerView.setHasFixedSize(true);
    recyclerView.setAdapter(adapter);

    L

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

    return v;
}

LocationsViewHolder：

public class LocationsViewHolder extends RecyclerView.ViewHolder{

private ImageView locationImage;
private TextView locationName;
private TextView locationAddress;

public LocationsViewHolder(View itemView) {
    super(itemView);

    locationName = (TextView)itemView.findViewById(R.id.location_name);
    locationAddress = (TextView)itemView.findViewById(R.id.location_address);
    locationImage = (ImageView) itemView.findViewById(R.id.location_image);
}

public void updateUI(HashMap<String, String > place){
    locationName.setText(place.get("name"));
}

}

LocationsAdapter：

public class LocationsViewHolder extends RecyclerView.ViewHolder{

private ImageView locationImage;
private TextView locationName;
private TextView locationAddress;

public LocationsViewHolder(View itemView) {
    super(itemView);

    locationName = (TextView)itemView.findViewById(R.id.location_name);
    locationAddress = (TextView)itemView.findViewById(R.id.location_address);
    locationImage = (ImageView) itemView.findViewById(R.id.location_image);
}
public void updateUI(HashMap<String, String > place){
    locationName.setText(place.get("name"));
}

}

card_location.xml：

    <?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/card">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        android:gravity="center_vertical">
        <LinearLayout
            android:layout_width="274dp"
            android:layout_height="match_parent"
            android:orientation="vertical"
            android:layout_margin="15dp">
            <TextView
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:text="Test"
                android:textColor="#2f2f2f"
                android:textSize="18dp"
                android:id="@+id/location_name"/>

            <TextView
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:text="Address Goes Here"
                android:textSize="16dp"
                android:paddingTop="5dp"
                android:id="@+id/location_address"/>

        </LinearLayout>

        <ImageView
            android:layout_width="50dp"
            android:layout_height="80dp"
            android:src="@drawable/ic_restaurant_black_24dp"
            android:adjustViewBounds="true"
            android:scaleType="centerCrop"
            android:id="@+id/location_image"
            android:layout_margin="10dp"/>

    </LinearLayout>

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

我认为这应该是所需的所有信息。如果您还有什么需要看的，请告诉我。

谢谢。

将卡片视图的高度更改为包装内容

android:layout_height="wrap_parent"
