我正在为我的应用程序的主屏幕设计布局。我正在使用带有网格布局的 RecyclerView 和其中的 CardView。我试图减少每张卡片之间的空间。下面是屏幕截图(打开了布局轮廓)以及我的布局文件。我怎样才能让每张卡片在垂直和水平方向上彼此靠近一点?我一直在研究边距,但似乎找不到合适的边距或填充值来执行此操作。
thumbnail_view.xml:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:id="@+id/card_view"
android:layout_width="match_parent"
android:layout_height="200dp"
card_view:cardCornerRadius="5dp"
card_view:cardMaxElevation="15dp"
card_view:cardElevation="10dp"
card_view:contentPadding="5dp"
android:padding="1dp"
card_view:cardBackgroundColor="@color/colorPrimary"
card_view:cardUseCompatPadding="true"
card_view:cardPreventCornerOverlap="false"
>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:id="@+id/card_list">
<ImageView
android:id="@+id/thumbnail"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"
android:gravity="center"
android:contentDescription="@string/video_thumbnail_description"
android:layout_weight="1"
/>
<TextView
android:id="@+id/video_title_view"
android:layout_height="match_parent"
android:layout_width="wrap_content"
android:layout_gravity="center"
android:gravity="center"
android:layout_weight="2"
/>
</LinearLayout>
</android.support.v7.widget.CardView>
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/activity_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="com.app.int_a.giantbombforandroid.main.mainscreen.MainActivity">
<android.support.v7.widget.RecyclerView
android:id="@+id/my_recycler_list"
android:scrollbars="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</RelativeLayout>
最佳答案
编辑这些属性
card_view:cardMaxElevation="1dp"
card_view:cardElevation="1dp"
所以完整的代码将是
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:id="@+id/card_view"
android:layout_width="match_parent"
android:layout_height="200dp"
card_view:cardCornerRadius="5dp"
card_view:cardMaxElevation="1dp"
card_view:cardElevation="1dp"
card_view:cardBackgroundColor="@color/colorPrimary"
card_view:cardUseCompatPadding="true"
card_view:cardPreventCornerOverlap="false"
>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:id="@+id/card_list">
<ImageView
android:id="@+id/thumbnail"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"
android:gravity="center"
android:src="@drawable/bag"
android:contentDescription="string/video_thumbnail_description"
android:layout_weight="1"
/>
<TextView
android:id="@+id/video_title_view"
android:layout_height="match_parent"
android:layout_width="wrap_content"
android:layout_gravity="center"
android:gravity="center"
android:text="lovelksdjslkdjlsdj"
android:layout_weight="3"
/>
</LinearLayout>
</android.support.v7.widget.CardView>
