安卓地图v2中的自定义信息窗口

Question

我想在安卓地图v2中开发一个自定义信息窗口。我想知道如何从信息窗口中删除白色背景，以及如何将圆圈半径之外的背景设置为透明黑

这是我的自定义信息窗口中的XML

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:background="@drawable/dp" 
    android:orientation="vertical"> 



</LinearLayout> 

这是我的代码来创建一个自定义信息窗口

getMap().getMap().setInfoWindowAdapter(new InfoWindowAdapter() { 

       @Override 
       public View getInfoWindow(Marker arg0) { 
        // TODO Auto-generated method stub 
        return null; 
       } 

       @Override 
       public View getInfoContents(Marker arg0) { 
        // TODO Auto-generated method stub 
        // Getting view from the layout file info_window_layout 
        View v = getLayoutInflater().inflate(R.layout.windowlayout, 
          null); 

        return v; 
       } 
      }); 
private SupportMapFragment getMap() { 
     return ((SupportMapFragment) getSupportFragmentManager() 
       .findFragmentById(R.id.map)); 
    } 

这是我的标志点击

@Override 
    public void onMapClick(LatLng point) { 
     // TODO Auto-generated method stub 
     Toast.makeText(getApplicationContext(), point.toString(), 
       Toast.LENGTH_SHORT).show(); 
     getMap().getMap().animateCamera(CameraUpdateFactory.newLatLng(point)); 
     CameraUpdate zoom = CameraUpdateFactory.zoomTo(8); 

     getMap().getMap().moveCamera(CameraUpdateFactory.newLatLng(point)); 
     getMap().getMap().animateCamera(zoom); 
     Marker marker; 
     getMap().getMap().clear(); 
     marker = getMap().getMap().addMarker(
       new MarkerOptions() 
         .draggable(true) 
         .position(point) 
         .title("Pick Up") 
         .icon(BitmapDescriptorFactory 
           .fromResource(R.drawable.marker))); 

     // marker.setPosition(point); 
     marker.showInfoWindow(); 
     rl.setVisibility(View.VISIBLE); 
    } 

这是我的地图布局

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" > 

    <FrameLayout 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:layout_above="@+id/data" 
     android:layout_alignParentTop="true" > 

     <fragment 
      android:id="@+id/map" 
      android:layout_width="match_parent" 
      android:layout_height="match_parent" 
      class="com.muratonnet.map.TouchableSupportMapFragment" /> 

     <RelativeLayout 
      android:id="@+id/rl" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:background="@drawable/circle" 
      android:layout_gravity="center" 
      android:visibility="gone" > 
     </RelativeLayout> 
    </FrameLayout> 

    <LinearLayout 
     android:id="@+id/data" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:layout_alignParentBottom="true" > 

     <include layout="@layout/data_table" /> 
    </LinearLayout> 

</RelativeLayout>

请设定在getInfoWindow()不getInfoContents();

您infowindow查看内容infoWindow这一点，你可以删除默认背景。

所以，你必须虚增您的看法是这样的：

getMap().setInfoWindowAdapter(new InfoWindowAdapter() { 

       @Override 
       public View getInfoWindow(Marker arg0) { 
        // TODO Auto-generated method stub 
        // Getting view from the layout file info_window_layout 
        View v = getLayoutInflater().inflate(R.layout.windowlayout, 
          null); 

        return v; 
       } 

       @Override 
       public View getInfoContents(Marker arg0) { 
        return null; 
       } 
      }); 
private SupportMapFragment getMap() { 
     return ((SupportMapFragment) getSupportFragmentManager() 
       .findFragmentById(R.id.map)); 
    }
