MapView 在对话框中显示较暗的地图 [英] MapView is showing Darker map inside Dialog

问题描述

我正在尝试在对话窗口中显示谷歌地图.对于此对话框，我使用以下代码行:

I am trying to display google map inside dialog window. For this dialog i am using following lines of code:

final Dialog dialog = new Dialog(SetProfileOnlineActivity.this);
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        dialog.setCanceledOnTouchOutside(false);
        dialog.setCancelable(false);
        dialog.setContentView(R.layout.pick_location_layout);
        Window w = dialog.getWindow();
        w.setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.MATCH_PARENT);
        dialog.show();

</android.support.constraint.ConstraintLayout>

现在我的问题是我的地图显示得更暗了.我还在对话框中显示编辑文本，该对话框显示完美，但地图只是显示较暗的组件，如图所示.那么，有什么办法可以让 mapview 和其他组件一样亮吗?

Now my problem is that my map is showing darker. I am also displaying edittext in dialog which is showing perfectly but map is only component which is showing darker as shown in image. So, is there any way to make mapview brighter as other components?

推荐答案

MapView 更新

dialog 中 mapView 的解决方案是像这样删除背景暗淡(针对您的代码进行了调整，只需粘贴在 dialog.show() 之前):

Solution for mapView in dialog is removing background dim like this (adjusted for your code, just paste before dialog.show()):

        w.clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);

不好的是我在 5 中找到了这个解决方案岁的问题

上一个答案

我刚刚检查了新地图"解决方案(在这里阅读更多):

I've just checked with "newer map" solution (read more here):

<fragment
    android:id="@+id/map"
    android:name="com.google.android.gms.maps.SupportMapFragment"
    app:mapType="normal"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

它显示明亮--图像在这里--
