android - 在 Google Maps api v2 中设置自定义 InfoWindow 的宽度

Question

我在 map 上创建了标记。当我点击它们时，自定义信息窗口总是和屏幕一样宽。

我尝试设置 layout_width="200dp" 但这没有帮助。我也试过设置

view.setLayoutParams(new LayoutParams(GetDipsFromPixel(200), GetDipsFromPixel(300)));

我可以通过设置 snippetUi.setWidth(GetDipsFromPixel(200)); 来设置 TextView 的宽度，但布局仍然保持屏幕宽度。

<?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"
    android:background="#FFFFFF"
    android:layout_marginLeft="30dp"
    android:layout_marginRight="30dp"
    android:padding="10dp" >

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        android:background="#FFFFFF"
        android:gravity="center_vertical">

        <ImageView
            android:id="@+id/worldmap_infowindow_profileimg"
            android:layout_width="20dp"
            android:layout_height="20dp"
            android:src="@drawable/noimage" />

        <TextView
            android:id="@+id/worldmap_infowindow_username"
            android:layout_width="wrap_content"

            android:text="To do No.2."
            android:textColor="#000000"
            android:textSize="16sp"
            android:textStyle="bold" 
            android:paddingLeft="5dp"/>
    </LinearLayout>

    <View android:id="@+id/separator" 
         android:background="#ababab" 
         android:layout_width = "fill_parent"
         android:layout_marginTop="3dp"
         android:layout_marginBottom="3dp"
         android:layout_height="1dp"/>

    <TextView
        android:id="@+id/worldmap_infowindow_name"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="See the Giza Pyramids"
        android:textColor="#000000"
        android:textSize="16sp"
        android:textStyle="bold" />

    <TextView
        android:id="@+id/worldmap_infowindow_details"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="It was fascinating! It's a shame that it was raining, though."
        android:textColor="#000000"
        android:textSize="14sp"
        android:textStyle="normal" />

</LinearLayout>

类:

 private class CustomInfoWindowAdapter implements InfoWindowAdapter {

       private View view;

       public CustomInfoWindowAdapter() {
            view = getLayoutInflater().inflate(R.layout.custom_infowindow, null);
       }

       @Override
       public View getInfoContents(Marker marker) {

           if (WorldMap.this.myMarker != null
                   && WorldMap.this.myMarker.isInfoWindowShown()) {
               WorldMap.this.myMarker.hideInfoWindow();
               WorldMap.this.myMarker.showInfoWindow();
           }
           return null;
       }

       @Override
       public View getInfoWindow(final Marker marker) {
           WorldMap.this.myMarker = marker;


           final String title = marker.getTitle();
           final TextView titleUi = ((TextView) view.findViewById(R.id.worldmap_infowindow_name));
           if (title != null) {
               titleUi.setText(title);
           } else {
               titleUi.setText("");
           }

           final String snippet = marker.getSnippet();
           final TextView snippetUi = ((TextView) view.findViewById(R.id.worldmap_infowindow_details));
           if (snippet != null) {
               snippetUi.setText(snippet);
           } else {
               snippetUi.setText("");
           }

           return view;
       }
   }

基本上你只需要在根下面有另一个层次的布局，像这样:

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

<LinearLayout
    android:layout_width="250dp"
    android:layout_height="wrap_content"
    android:background="@android:color/white"
    android:orientation="horizontal">
    ...
