Google MapView Not Taking Full Screen... Please Help

[koeks525]

Hi Everyone,

I am trying to set up my MapView to take up the full screen of the mobile device. I have tried wrapping a FrameLayout around the MapView, that didn't work. I tried setting the layout_weight of the MapView to 1, that didn't work. I tried using a MapFragment instead of the MapView, that didn't work. I have been stuck on this problem for days now and I am really not sure what I am doing wrong.

The app has one main activity - I have created several Fragments, which I will switch between, as the app gets used. Could the problem be with the way I have laid out my MainActivity (the activity where fragments will be swtiched onto)?

I have implemented the needed lifecycle methods for the MapView, on my fragment. Here is the XML Layout for the Fragment with the MapView:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:layout_width="fill_parent"
              android:layout_height="fill_parent"
              android:id = "@+id/mapRouteView"
              android:orientation="vertical"
              android:weightSum="1"
              >
    <com.google.android.gms.maps.MapView
        android:layout_marginTop="10dp"
        android:id = "@+id/mapRouteMapView"
        android:layout_height="0dp"
        android:layout_width="match_parent"
        android:apiKey="@string/maps_api_key"
        android:visibility="visible"
        android:layout_weight="1"
        >
    </com.google.android.gms.maps.MapView>
</LinearLayout>

This is the XML Layout for the MainActivity - where Fragments will be switched as the app is used:

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    tools:context="allblacks.com.ibaleka_android_prototype.MainActivity"
    android:orientation="vertical">
    <android.support.v7.widget.Toolbar
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id = "@+id/MainActivityToolbar"
        android:background="@color/colorPrimary"
        >
        <ImageView
            android:layout_width="30dp"
            android:layout_height="30dp"
            android:id = "@+id/MainActivityImageView"
            android:layout_marginRight="5dp"
            android:layout_marginLeft="1dp"/>
        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            style="@style/ToolbarTextView"
            android:id = "@+id/MainActivityTextView"
            android:textAlignment="center"
            />
    </android.support.v7.widget.Toolbar>
    <android.support.v4.widget.DrawerLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id = "@+id/menuDrawerLayout"
        >
        <ScrollView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:id = "@+id/mainActivityScrollView"
            android:fitsSystemWindows="true"
            >
            <FrameLayout
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:id = "@+id/MainActivityContentArea"
                >
            </FrameLayout>
        </ScrollView>
        <android.support.design.widget.NavigationView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:id = "@+id/mainActivityNavigationView"
            android:layout_gravity="start"
            android:textAlignment="center"
            app:itemTextColor="@android:color/black"
            ></android.support.design.widget.NavigationView>
    </android.support.v4.widget.DrawerLayout>
</LinearLayout>

This is the outcome I get each time for the map: http://imgur.com/uSAi3Vm

Please Help Me... Thanks.
