我正在尝试创建一个名为CardView的自定义WeekView对象。WeekView扩展了CardView。我在XML文件中有一个CardView布局。如何使WeekView从XML文件中“复制”布局?
简单地说,我希望能够做到这一点:
WeekView weekCard = new WeekView();
mainLayout.addView(weekCard);在主活动中,mainLayout是一个空的线性布局。WeekCard应该看起来像XML布局文件中的卡片。
以下是XML文件的缩短版本:

在主视图中使用链接到卡片视图的include标记
<include
android:id="@+id/some_id"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
layout="@layout/your_card_layout" />若要包含要重用的布局,请执行以下操作。
访问它的内部视图
View includedLayout = findViewById(R.id.some_id);
Button buttonInsideTheIncludedLayout = (Button)includedLayout.findViewById(R.id.button);发布于 2018-07-09 16:52:25
也许这个答案已经晚了,但我是安卓开发的新手,我认为你需要的是LayoutInflater.inflate()方法。
膨胀XML布局并将其作为View返回的方法,在您的例子中是CardView。
我的代码示例:
LayoutInflater inflater = LayoutInflater.from(getContext());
CardView newSessionGroupCardView = (CardView) inflater.inflate(R.layout.session_group_cardview, null);
LinearLayout linearParentLayout = getView().findViewById(R.id.session_group_layout);
linearParentLayout.addView(newSessionGroupCardView);也许这能帮上忙。进一步阅读布局充气器
