Question

我正在尝试使用Google Map制作屏幕。

此屏幕有两个部分。第一部分包括Button TextView和ListView，位于Screen的顶部。第二部分包括MapView（谷歌地图）和屏幕底部的位置。

如何制作？

我做到了。但没有运气。它抛出了这个例外：

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_width="fill_parent"
android:layout_height="fill_parent"
android:layout_gravity="top|center_vertical">

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上放置你需要的内容...... 并在下面的片段放置地图片段......

我希望它对你有用......

<强> nested_frag.xml

<FrameLayout
    android:id="@+id/top_content"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="0.7"
    android:background="#fff2ff" >
</FrameLayout>

<FrameLayout
    android:id="@+id/map"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    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;
}

如何使用MapView制作2个分屏？
