我对OSM Map的片段布局有疑问。我希望以全屏模式显示活动中的片段。 但是，地图仅显示在屏幕的三分之二处。
如何实现这一目标？ 这样做只能编辑.xml文件还是我需要在清单或主要活动中进行任何更改？
这里是.xml：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical" >
<fragment
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="8.01" >
</fragment>
</LinearLayout>
这是MapFragment.java文件：
