我将AlertDialog与几个自定义布局一起使用,但其中一个存在一个奇怪的问题: 我正在尝试在AlertDialog中使用Google地图视图:

   // this common code used for all alert dialogs
   // I have different dialogIds so specific code is used where needed.

   AlertDialog.Builder builder = new AlertDialog.Builder(mActivity);
   final View view = viewInitializer.getView(dialogId, mActivity);
   builder.setMessage(message);
   builder.setCancelable(false);
   builder.setView(view)
   // Add action buttons
     .setPositiveButton("Ok", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int id) {
           // do something....
        }
   })
   .setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int id) {
        }
   });

   Dialog dialog = builder.create();
   builder.show();

   .......
   // map view specific code
   final MapView mapView = view.findViewById(R.id.mapView);
   MapsInitializer.initialize(mActivity);

   mapView.onCreate(dialog.onSaveInstanceState());
   mapView.onResume();// needed to get the map to display immediately
   mapView.getMapAsync(new OnMapReadyCallback() {
      @Override
      public void onMapReady(GoogleMap googleMap) {
        final GoogleMap gmap = googleMap;
        gmap.setMinZoomPreference(12);
        LatLng ny = new LatLng(42.6021767,23.4674597);
        gmap.moveCamera(CameraUpdateFactory.newLatLng(ny));
      }
   });
   ...........

-----------布局模板:------------     //可以的对话框之一。

<?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:gravity="center_horizontal"
    android:orientation="vertical">

    <NumberPicker
        android:id="@+id/seatsCountPicker"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:gravity="top"/>

</LinearLayout>

// the dialog with map view that are not ok.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center_horizontal"
    android:orientation="vertical"
    android:weightSum="5">

    <Spinner
        android:id="@+id/pointPicker"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:entries="@array/points"
        android:gravity="top"
        android:layout_weight="1"/>

    <Spinner
        android:id="@+id/pointPicker2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:entries="@array/points"
        android:gravity="top"
        android:layout_weight="1"/>

    <com.google.android.gms.maps.MapView
        android:id="@+id/mapView"
        android:layout_width="match_parent"
        android:layout_height="0pt"
        android:layout_weight="3"
        android:gravity="top"/>

</LinearLayout>

其他对话框都可以 带地图的对话框没有按钮。我试图设置较小的尺寸和不同的Mapview权重,因为我认为按钮在地图后面。但仍然没有按钮。

有什么想法吗?

[已解决] 嗯,奇怪。如果我删除“ layout_weight”并仅使用固定值作为高度,那就可以了。现在,我只需要找到如何处理不同尺寸的屏幕。

屏幕截图已附上-正常的对话框和不带按钮的地图视图对话框。enter image description here
