我正在尝试在layout

的底部创建一个由mapview和textfield以及buttons对齐组成的layout

我试过使用这个xml文件：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:orientation="vertical"
  android:layout_width="match_parent"
  android:layout_height="match_parent">

  <com.google.android.maps.MapView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/google_maps"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:clickable="true"
    android:apiKey="@string/maps_key" />
    <LinearLayout 
        android:id="@+id/linearLayout1" 
        android:layout_height="wrap_content" 
        android:layout_width="match_parent"
        android:padding="5dp" 
        android:orientation="vertical">
        <TextView 
            android:text="@string/txtLocationDescription" 
            android:layout_height="wrap_content" 
            android:id="@+id/textView1" 
            android:layout_width="wrap_content"></TextView>
        <EditText 
            android:id="@+id/editText1" 
            android:layout_height="wrap_content" 
            android:layout_width="match_parent"></EditText>
        <LinearLayout 
        android:id="@+id/linearLayout2" 
        android:layout_height="wrap_content" 
        android:orientation="horizontal"
        android:weightSum="1.0"
        android:layout_width="match_parent">
            <Button android:id="@+id/Button1" 
                    android:layout_width="wrap_content" 
                    android:layout_height="wrap_content" 
                    android:layout_weight="0.5"
                    android:text="@string/btnAddNewLocation"></Button>
            <Button android:layout_height="wrap_content" 
                    android:id="@+id/button2" 
                    android:layout_width="wrap_content"
                    android:layout_weight="0.5"
                    android:text="@string/btnCancelAddingLocation"></Button>

        </LinearLayout>
    </LinearLayout>
</LinearLayout>

但我收到了这个错误：

问题是什么，我该怎么做？

答案 0 :(得分：3)

你不能把东西放在MapView里面。更好的解决方案是将MapView置于RelativeLayout内，并在顶层RelativeLayout内的按钮上布置按钮。

编辑：

基本示例：

<RelativeLayout>
   <MapView></MapView>
   <Button></Button>
   <Button></Button>
   <TextView></TextView>
   *****Any other layout you want ****
</RelativeLayout>

您的活动应该扩展MapACtivity以避免此异常发生。在崩溃日志中查看此行。

MapViews can only be created inside instances of MapActivity.

答案 2 :(得分：0)

使用relativelayout，alignparent variants。
