在安卓工作室中与其他小部件一起显示地图视图

Question

请我需要帮助，我一直在努力解决这个问题，我想显示一个 MapView、一个按钮和两个文本视图。我已经尽我所能，看了很多教程，但仍然没有弄清楚，我想要的不是屏幕上显示的内容，地图显示得很好，但其他小部件没有显示，地图顶部出现一个搜索栏我不知道如何摆脱。并且我提前为我糟糕的代码编写道歉，我不是专家。请帮忙。谢谢。

Answer 1

无法创建整个布局，但我下面是我为自定义我的地图视图设计而创建的布局：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<fragment 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"
android:id="@+id/map"
tools:context=".MapsActivity"
android:name="com.google.android.gms.maps.SupportMapFragment" />
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_marginTop="10dp"
android:layout_marginRight="10dp"
android:layout_marginLeft="10dp"
android:elevation="10dp"
android:background="@drawable/white_border"
android:id="@+id/relLayout1">
<ImageView
android:layout_width="15dp"
android:layout_height="15dp"
android:id="@+id/ic_magnify"
android:layout_centerVertical="true"
android:layout_marginLeft="10dp"
android:src="@drawable/ic_magnify"/>
<AutoCompleteTextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_toRightOf="@+id/ic_magnify"
android:layout_centerVertical="true"
android:textSize="15sp"
android:textColor="#000"
android:id="@+id/input_search"
android:background="@null"
android:hint="Enter Address, City or Zip Code"
android:imeOptions="actionSearch"/>

</RelativeLayout>
<ImageView
android:layout_width="40dp"
android:layout_height="40dp"
android:layout_below="@id/relLayout1"
android:layout_alignParentRight="true"
android:layout_marginRight="10dp"
android:layout_marginTop="10dp"
android:scaleType="centerCrop"
android:id="@+id/ic_gps"
android:src="@drawable/ic_gps"/>
<ImageView
android:layout_width="40dp"
android:layout_height="40dp"
android:layout_below="@+id/relLayout1"
android:layout_marginLeft="10dp"
android:layout_marginTop="15dp"
android:scaleType="centerCrop"
android:id="@+id/place_info"
android:src="@drawable/ic_info"/>

可绘制/white_boarder.xml

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle">
<solid android:color="#fff"/>
<corners android:radius="5dp"/>
</shape>
</item>
</layer-list>

最后，如果你想禁用地图的defult小部件，你可以用getUiSettings((来做。

yourMap.getUiSettings().setMyLocationButtonEnabled(false);
