膨胀时，RelativeLayout 不遵守设置的宽度
我有一个relativeLayout，我想使用theme.dialog android主题，它的宽度应该设置为240dip。当我在 xml 中指定整个布局及其子布局时，这是有效的。但是，当我尝试膨胀 xml 以添加更多视图（下面的代码）时，布局会填充屏幕的宽度。
Context context = this;
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
RelativeLayout header = (RelativeLayout) inflater.inflate(R.layout.headphonepopupheader, null);
headphonepopup.xml：
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="240dp"
android:layout_height="wrap_content" >
<ImageButton
android:id="@+id/closebutton"
android:layout_width="24dp"
android:layout_height="24dp"
android:layout_alignParentTop="true"
android:layout_alignParentRight="true"
android:layout_marginLeft="216dp"
android:background="@drawable/closebutton" />
</RelativeLayout>
有办法解决这个问题吗？
I have a relativeLayout that I would like to use the theme.dialog android theme, it should have a set width of 240dip. When I specify the whole layout and it's children in xml, this works. However, when I try to inflate the xml to add more views (code below), the Layout fills the width of the screen.
Context context = this;
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
RelativeLayout header = (RelativeLayout) inflater.inflate(R.layout.headphonepopupheader, null);
headphonepopup.xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="240dp"
android:layout_height="wrap_content" >
<ImageButton
android:id="@+id/closebutton"
android:layout_width="24dp"
android:layout_height="24dp"
android:layout_alignParentTop="true"
android:layout_alignParentRight="true"
android:layout_marginLeft="216dp"
android:background="@drawable/closebutton" />
</RelativeLayout>
Is there a way to solve this?

膨胀
RelativeLayout时，请勿使用其中的inflate()方法签名。相反，请使用inflate()将父容器作为第二个参数，将布尔值作为第三个参数。在第二个参数中提供RelativeLayout的最终父级，如果您不希望立即添加RelativeLayout，请将false作为第三个参数传递。至少，当使用
RelativeLayout作为ListView中的行的基础时，此秘籍可以解决各种RelativeLayout膨胀问题。When inflating a
RelativeLayout, do not use theinflate()method signature that you have there. Instead, use theinflate()that takes the parent container as the 2nd parameter and a boolean as the third. Supply the eventual parent for theRelativeLayoutin the 2nd parameter, and if you do not want theRelativeLayoutadded immediately, passfalseas the 3rd parameter.Leastways, this recipe clears up all sorts of
RelativeLayoutinflation problems when using aRelativeLayoutas the basis for a row in aListView.
