问题：
Android谷歌地图不适用于幻灯片菜单
胡俊弼
我有一个应用程序，使用gmap从webservice获取标记，并将其显示在地图上。这是一个很好的布局代码

我想添加到幻灯片菜单，而不是主屏幕中的开关。一旦我将幻灯片菜单的代码添加到此文件的末尾，我可以看到幻灯片菜单，但谷歌地图停止工作。这是不起作用的新代码

根据文件：
要添加抽屉菜单，请将带有DrawerLayout对象的用户交互界面声明为布局的根视图。在DrawerLayout中，添加一个包含屏幕主要内容的视图（抽屉隐藏时的主要布局）和另一个包含抽屉菜单内容的视图。
因此，android.support.v4.widget.DrawerLayout必须是根视图（在您的情况下，您只需在现有xml的末尾添加它）。
这是一个带有map和DrawerLayout的工作xml示例：
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout android:id="@+id/drawer_layout" xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent">
<fragment
android:id="@+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<ListView
android:id="@+id/left_drawer"
android:layout_width="300dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="@android:color/transparent"
android:dividerHeight="0dp"
android:paddingLeft="10dp"
android:paddingRight="10dp"/>
</android.support.v4.widget.DrawerLayout>
更新：一个简单的示例，使用上面的答案和来自列表视图自定义适配器的拟议代码来说明如何创建带有开关的左抽屉：

android:layout_width="300dp"
android:layout_height="match_parent"

地图活动性。Java语言
public class MapsActivity extends FragmentActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps);
ListView drawerView = (ListView) findViewById(R.id.left_drawer);
List<String> switches = new ArrayList<String>();
switches.add("Switch 1");
switches.add("Switch 2");
switches.add("Switch 3");
ListAdapter adapter = new ListAdapter(this, R.layout.itemlistrow, switches);
drawerView.setAdapter(adapter);
}
public class ListAdapter extends ArrayAdapter<String> {
public ListAdapter(Context context, int textViewResourceId) {
super(context, textViewResourceId);
}
public ListAdapter(Context context, int resource, List<String> items) {
super(context, resource, items);
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null) {
LayoutInflater vi;
vi = LayoutInflater.from(getContext());
v = vi.inflate(R.layout.itemlistrow, null);
}
String p = getItem(position);
if (p != null) {
TextView tt1 = (TextView) v.findViewById(R.id.name);
Switch switchI = (Switch) v.findViewById(R.id.value);
if (tt1 != null) {
tt1.setText(p);
}
switchI.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
switch (position) {
case 1:
// TODO: Behaviour of switchI on first row
break;
case 2:
// TODO: Behaviour of switchI on second row
break;
default:
// TODO: Default behaviour
break;
}
}
});
}
return v;
}
}
}
UPDATE：xml，每行有两个开关
itemlistrow。xml
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:paddingBottom="10dp"
android:paddingLeft="20dp"
android:paddingRight="20dp"
android:paddingTop="10dp">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_weight="1">
<TextView
android:id="@+id/name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="15dp"
android:gravity="center_horizontal"
android:text="SW1"
android:textColor="#fff"/>
<Switch
android:id="@+id/value"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:clickable="true"
android:textColor="#fff"/>
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_weight="1">
<TextView
android:id="@+id/name2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="15dp"
android:gravity="center_horizontal"
android:text="SW2"
android:textColor="#fff"/>
<Switch
android:id="@+id/value2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:clickable="true"
android:textColor="#fff"/>
</LinearLayout>
</LinearLayout>
或者，删除TextViews并使用Switch的文本属性：
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:paddingBottom="10dp"
android:paddingLeft="20dp"
android:paddingRight="20dp"
android:paddingTop="10dp">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_weight="1">
<Switch
android:id="@+id/value"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="SW1"
android:clickable="true"
android:textColor="#fff"/>
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_weight="1">
<Switch
android:id="@+id/value2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="SW2"
android:clickable="true"
android:textColor="#fff"/>
</LinearLayout>
</LinearLayout>
修改MapsActive以在上面的同一行视图上使用两个开关（警告：未完全html" target="_blank">测试）：

ListAdapter adapter = new ListAdapter(this, R.layout.itemlistrow, switches);
drawerView.setAdapter(adapter);
}
public class ListAdapter extends ArrayAdapter<RowItem> {
public ListAdapter(Context context, int textViewResourceId) {
super(context, textViewResourceId);
}
public ListAdapter(Context context, int resource, List<RowItem> items) {

public View getView(final int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null) {

v = vi.inflate(R.layout.itemlistrow, null);
}
RowItem p = getItem(position);
if (p != null) {

tt2.setText(p.getSwitch2Name());
switchI1.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

}
});
switchI2.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
switch (position) {
case 0:
// TODO: Behaviour of switchI2 on first row
break;
case 1:
// TODO: Behaviour of switchI2 on second row
break;
default:

}
}
});
}
return v;
}
}
private class RowItem {

所以我看到了一个特殊的例外，我敢肯定的是谷歌地图的绘图代码。 我有一个片段，在那里我以编程方式添加了一个支持地图片段，然后我在其中操纵谷歌地图实例。 这是stacktrace： 我无法可靠地复制它（尽管这种情况经常发生），我已经查看了ReadWriteDirectByteBuffer和ShortToByteBufferAdapter，但没有任何东西突然出现在我面前。 有什么想法吗？
