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"?>

    android:layout_height="wrap_content"

    android:layout_marginRight="30dp"
    android:padding="10dp" >

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;
       }
   }

最佳答案

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">
    ...
