mapview Java,java – 如何在mapview周围绘制边框

我试图在单击按钮时在mapView周围绘制边距.

所以这就是我所尝试过的,它不起作用. mapview位于相对布局中.

LayoutInflater inflater = getLayoutInflater();

LinearLayout mView = (LinearLayout) inflater.inflate(

R.layout.map_view_create_ps, mapView, false);

GeoPoint viewLoc = mapView.getMapCenter();

MapView.LayoutParams params = new MapView.LayoutParams(

LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT,

viewLoc,

MapView.LayoutParams.BOTTOM_CENTER);

mView.setLayoutParams(params);

mapView.addView(mView);

mView.setVisibility(View.VISIBLE);

单击按钮时会调用上面的内容

我的create_ps_layout就是这样

android:orientation="vertical" android:layout_width="fill_parent"

android:layout_height="fill_parent" android:background="@android:color/transparent">

android:id="@+id/linearLayout1" android:orientation="vertical"

android:layout_height="fill_parent"

android:background="@drawable/rounded_boarder">

可绘制的背景是这样的

android:shape="rectangle" android:padding="10dp">

android:bottomLeftRadius="30dp" android:topLeftRadius="30dp"

android:topRightRadius="30dp" />

这不起作用,但是当你选择按钮时,你们可以指出我在如何在mapview周围绘制边框的正确方向吗？
