如何在同一屏幕上显示地图视图和列表视图？
通常我只会将活动分开，但我想显示一个具有视图文本视图、列表和地图视图的屏幕。我不知道如何去做，因为我知道活动只能扩展列表视图或地图视图。
我有一个像这样的 xml 文件，我们将其称为 main.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout android:id="@+id/relativeLayout1"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="fill_parent" android:layout_width="fill_parent">
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="fill_parent"
android:orientation="vertical" android:background="#ffffff">
<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content" android:id="@+id/tvName"
android:textColor="@color/dark" android:text="Name"></TextView>
<EditText android:layout_width="match_parent"
android:layout_height="wrap_content" android:id="@+id/etName"></EditText>
<Button android:layout_width="wrap_content"
android:layout_height="wrap_content" android:id="@+id/btnAdd"
android:text="Add location"></Button>
<ListView android:layout_height="wrap_content"
android:layout_width="match_parent" android:id="@android:id/list"></ListView>
</LinearLayout>
和另一个 xml 文件，它只是一个大地图
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="fill_parent">
<com.google.android.maps.MapView
android:id="@+id/mapsView" android:layout_width="fill_parent"
android:layout_height="fill_parent" android:clickable="true"
android:apiKey="myapikey" />
主要活动用列表填充第一个 xml 工作表，但是如何将地图添加到此？我是否嵌套一个扩展地图活动类的类以及如何添加视图？ 这就是我的想法
public class AddLocationActivity extends ListActivity{
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
getWindow().setLayout(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);
}
public class ShowMap extends MapActivity{
public ShowMap(){
//maybe get the map.xml and add the view somehow?
}
@Override
protected boolean isRouteDisplayed() {
// TODO Auto-generated method stub
return false;
}
}
}
Usually I would just seperate out the activities but I want to show a screen that has a view text views, a list, and then a map view. I'm not sure how to go about doing that because I know the activity can only extend either listview or mapview.
I have one xml file like this we'll call it the main.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout android:id="@+id/relativeLayout1"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="fill_parent" android:layout_width="fill_parent">
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="fill_parent"
android:orientation="vertical" android:background="#ffffff">
<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content" android:id="@+id/tvName"
android:textColor="@color/dark" android:text="Name"></TextView>
<EditText android:layout_width="match_parent"
android:layout_height="wrap_content" android:id="@+id/etName"></EditText>
<Button android:layout_width="wrap_content"
android:layout_height="wrap_content" android:id="@+id/btnAdd"
android:text="Add location"></Button>
<ListView android:layout_height="wrap_content"
android:layout_width="match_parent" android:id="@android:id/list"></ListView>
</LinearLayout>
and another xml file that is just a big map
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="fill_parent">
<com.google.android.maps.MapView
android:id="@+id/mapsView" android:layout_width="fill_parent"
android:layout_height="fill_parent" android:clickable="true"
android:apiKey="myapikey" />
The main activity inflates the first xml sheet with the list, but then how do I add the map to this? Do I nest a class that extends the map activity class and some how add the view?
This is what I was thinking
public class AddLocationActivity extends ListActivity{
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
getWindow().setLayout(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);
}
public class ShowMap extends MapActivity{
public ShowMap(){
//maybe get the map.xml and add the view somehow?
}
@Override
protected boolean isRouteDisplayed() {
// TODO Auto-generated method stub
return false;
}
}
}

就像 mkso 评论的那样，您不需要从
ListActivity扩展来使用ListView，请参阅 这是一个例子（不是最好的，但我可以很快找到）。只需按照您想要的方式创建布局，从MapActivity扩展并通过调用findViewById()使用ListView即可。Like mkso commented, you do not need to extend from
ListActivityto use aListView, see this for an example (not the best, but what I could find quickly). Just create the layout how you want it, extend fromMapActivityand use theListViewby callingfindViewById().
