【英文标题】：How to make 2 parted screen with MapView?

【问题描述】：

我正在尝试使用 Google 地图制作屏幕。

此屏幕有 2 个部分。第一部分包括按钮 TextView 和 ListView 以及位于屏幕顶部的位置。第二部分包括 MapView（谷歌地图）和屏幕底部的位置。

如何制作？

我已经做到了。但没有运气。它抛出这个异常：

我有抛出异常的代码行：MyCustomActivity.java:457

这一行是：setContentView(R.layout.my_layout);

我的 XML 是：

<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_
android:layout_
android:layout_gravity="top|center_vertical">
<com.mypackagename.uk.MyLayout
<TableLayout android:layout_ 
    android:layout_>
    <TableRow android:layout_ android:layout_ android:id="@+id/my_row1">
        <TableLayout android:layout_ 
            android:layout_ android:layout_weight="1">     
            <TableRow android:layout_marginTop="5dip" android:layout_ android:layout_>
                <TextView android:layout_></TextView>

【问题讨论】：

您需要在堆栈跟踪中进一步查看，以找到触发您在上面粘贴的行的异常。我建议您编辑此问题并粘贴到整个堆栈跟踪中，而不仅仅是这一行。

【参考方案1】：

我也有问题..我确实喜欢这个... 创建一个可以接受两个片段的布局...... .. 在 top_fragment 放置您需要的任何内容...... 并在下面的片段上放置地图片段...

希望对你有用……

nested_frag.xml

<FrameLayout
    android:id="@+id/top_content"
    android:layout_
    android:layout_
    android:layout_weight="0.7"
    android:background="#fff2ff" >
</FrameLayout>

<FrameLayout
    android:id="@+id/map"
    android:layout_
    android:layout_
    android:layout_weight="0.3"
    android:background="#fff2ff" >
</FrameLayout>

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) 
    View view = inflater.inflate(R.layout.nested_frag, container, false);
    b = getArguments();

    Fragment map = new MapFragment();

    map.setArguments(b);

    FragmentTransaction trans = getChildFragmentManager()
            .beginTransaction();
    trans.add(R.id.top_content, new HomeScreen());
    trans.add(R.id.map, map).addToBackStack("somestack").commit();

    return view;
