Android - 如何将布局加载到视图中？

Question

似乎没有例子可行。我有一个RelativeLayout：

<View
    android:id="@+id/latest_info_container"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">
</View>

在活动中：

LayoutInflater inflater = getLayoutInflater();
View latest_info_content = inflater.inflate(R.layout.latest_info, null);
View latest_info_container = (View)findViewById(R.id.latest_info_container);
((ViewGroup)latest_info_container).addView(latest_info_content,0);

应用程序崩溃 - 错误为android.view.View cannot be cast to android.view.ViewGroup。 当我在布局中将<View>更改为<ViewGroup>时，错误为can't instantiate class android.view.ViewGroup

Answer 1

尝试用Linear / RelativeLayout替换你的View，它应该有效：

<RelativeLayout
    android:id="@+id/latest_info_container"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">
</RelativeLayout>

LayoutInflater inflater = getLayoutInflater();
View latest_info_content = inflater.inflate(R.layout.latest_info, null);
RelativeLayout latest_info_container = (RelativeLayout)findViewById(R.id.latest_info_container);
latest_info_container.addView(latest_info_content,0);

Answer 2

只有ViewGroup可以有孩子。 View不能。
