Question

所以，基本上我试图在我的地图片段顶部放置一个按钮，但它似乎无法工作，尽管地图工作完全正常。即使在广泛搜索Google之后，我也找不到可执行的答案。

这是我的地图片段 -

public class Tab1 extends SupportMapFragment implements
        GoogleApiClient.OnConnectionFailedListener,
        GoogleApiClient.ConnectionCallbacks,
        GoogleMap.OnInfoWindowClickListener, OnMapReadyCallback,

        initListeners();
    }

    }

    }

    @Override
    public boolean onClusterItemClick(MyItem myItem) {
        return false;
    }
}

这是我的xml -

<?xml version="1.0" encoding="utf-8"?>

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">

<com.google.android.gms.maps.MapView
    android:id="@+id/mapView"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

<Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="New Button"
    android:id="@+id/button2"
    android:layout_gravity="center" />
</FrameLayout>

Answer 1

使用FrameLayout代替RelativeLayout，如下所示。

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <com.google.android.gms.maps.MapView 
            android:id="@+id/mapView"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />

        <Button
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="New Button"
            android:id="@+id/button2"
            android:layout_gravity="left|top" />
    </FrameLayout>

无法将按钮与谷歌地图一起放置
