在 android 中的布局中将视图设置为 match_parent
Set view to match_parent in a layout in android
信息窗口布局有一个小问题。
我试图在布局中设置一个视图以匹配父级的宽度,但我在左右边距中出现了一些小间隙。
我尝试使用 LinearLayout、RelativeLayout 和 ConstraintLayout 作为根视图,我得到了相同的结果。
这是我的 XML:

以及截图:
我是这样给它充气的:
mMap.setInfoWindowAdapter(new GoogleMap.InfoWindowAdapter()
{
@Override
public View getInfoWindow(Marker marker)
{
return null;
}
@Override
public View getInfoContents(Marker marker)
{
View view =
getLayoutInflater().inflate(R.layout.fragment_info_view,
null);
profileImageInfoView = (CircleImageView)
view.findViewById(R.id.profile_image_info_view);
ownerName =
(TextView)view.findViewById(R.id.owner_name);
eventTitle = (TextView)
view.findViewById(R.id.event_title_info_view);
return view;
}
});

编辑:
在 dimens.xml
中更改此设置
<dimen name="activity_horizontal_margin">0dp</dimen>
<dimen name="activity_vertical_margin">0dp</dimen>
使您的 ConstraintLayout 的宽度匹配 parent。也许您的 ConstraintLayout 从其 child.
中获取宽度大小
您在 getInfoContents()
方法中编写的代码将其移动到 getInfoWindow()
方法中。
如果您使用 getInfoContents()
方法,那么它会添加带有一些填充的白色背景,但 getInfoWindow()
方法不会这样做。
更新后的代码将是:
mMap.setInfoWindowAdapter(new GoogleMap.InfoWindowAdapter() {
@Override
public View getInfoWindow(Marker marker) {
View view = getLayoutInflater().inflate(R.layout.fragment_info_view, null);
profileImageInfoView = (CircleImageView)
view.findViewById(R.id.profile_image_info_view);
ownerName = (TextView)view.findViewById(R.id.owner_name);
eventTitle = (TextView)view.findViewById(R.id.event_title_info_view);
return view;
}
@Override
public View getInfoContents(Marker marker) {
return null;
}
});
