如何把绘制作为信息窗口（Android版谷歌地图API v2）的背景？(How to put dra

这是我为我的信息窗口自定义布局：

<RelativeLayout 
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/bg_infowindow" >
    <LinearLayout
            android:id="@+id/text_box"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:orientation="vertical" >
        <TextView 
            style="@style/TexTitle"
            android:id="@+id/title"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" />
    <TextView 
            style="@style/TextDistance"
            android:id="@+id/distance"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" />
    </LinearLayout>
</RelativeLayout>

这是我的自定义适配器：

public class MapInfoWindowAdapter implements InfoWindowAdapter{

    private LayoutInflater inflater;
    private Context context;

    public MapInfoWindowAdapter(Context context){
        inflater = (LayoutInflater) context.getSystemService( Context.LAYOUT_INFLATER_SERVICE );
        this.context = context;
    }

    @Override
    public View getInfoContents(Marker marker) {

        // Getting view from the layout file
        View v = inflater.inflate(R.layout.map_popup, null);

        TextView title = (TextView) v.findViewById(R.id.title);
        title.setText(marker.getTitle());

        TextView address = (TextView) v.findViewById(R.id.distance);
        address.setText(marker.getSnippet());

        return v;
    }

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

}

这是结果：

不过，我想自定义绘制为我的信息窗口的唯一背景下，如何实现这一目标？

Answer 1:

在替换代码getInfoContents与getInfoWindow 。它们之间的区别是getInfoContents包您View在ViewGroup的默认背景。

@Override
public View getInfoWindow(Marker marker) {

    // Getting view from the layout file
    View v = inflater.inflate(R.layout.map_popup, null);

    TextView title = (TextView) v.findViewById(R.id.title);
    title.setText(marker.getTitle());

    TextView address = (TextView) v.findViewById(R.id.distance);
    address.setText(marker.getSnippet());

    return v;
}

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

Answer 2:

试试这个..

custom_infowindow.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">


<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#80000000" 
android:orientation="vertical">

<ImageView
    android:src="@drawable/ic_launcher"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" 
    android:padding="10dp"/>

</LinearLayout> 

</LinearLayout>


googleMap.setInfoWindowAdapter(new InfoWindowAdapter() 
{

        public View getInfoWindow(Marker arg0)
        {
            View v = getLayoutInflater().inflate(R.layout.custom_infowindow, null);
            return v;
        }

        public View getInfoContents(Marker arg0) 
        {
           return null;
        }
    });
