我得到了错误
Unable to start activity ComponentInfo{de.androidbuch.activiti/de.androidbuch.activiti.task.Activity}: android.view.InflateException: Binary XML file line #11: Error inflating class fragment
当我通过肖像和横向模式切换时.我正在使用片段.我的xml是:
<LinearLayout android:id="@+id/mainLayout"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<ListView android:id="@+id/android:list"
android:layout_height="wrap_content"
android:layout_width="fill_parent"/>
<fragment android:id="@+id/fragmentDetails"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
class="de.androidbuch.activiti.task.TaskDetailsFragment"/>
</LinearLayout>
如果我通过横向和纵向模式切换一切正常.但是当我点击我的片段(我可以看到我的片段)然后切换到另一种模式时,我得到了错误.知道怎么解决吗？在这里找到了一些答案,但这些都没有帮助我...

问题是在附加MapFragment之后我需要获得一个GoogleMap 放置Marker的引用,但是该getMap()方法返回null(因为片段onCreateView()还没有被调用).
我查看了演示示例代码,我发现他们使用的解决方案是初始化MapFragment onCreate()并在调用onResume()之后获取对GoogleMap的引用onCreateView().
我需要在MapFragment初始化之后立即获取对GoogleMap的引用,因为我希望用户能够使用按钮显示或隐藏地图.我知道一个可能的解决方案是如上所述在开始时创建Map并且只是设置它的可见性消失了,但我希望默认情况下关闭地图,这样如果没有明确要求它就不会占用用户的带宽为了它.
我试过了MapsInitializer,但也没用.我有点卡住了.有任何想法吗？这是我到目前为止的测试代码:
public class ParadaInfoFragment extends BaseDBFragment {
// BaseDBFragment is just a SherlockFragment with custom utility methods.
private static final String MAP_FRAGMENT_TAG = "map";
private GoogleMap mMap;
private SupportMapFragment mMapFragment;
private TextView mToggleMapa;
private boolean isMapVisible = false;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_parada_info, container, false);
mToggleMapa = (TextView) v.findViewById(R.id.parada_info_map_button); …我有一个片段是Viewpager的一部分,我想在该片段中使用Google Map V2.这是我到目前为止所尝试过的,
在我的片段中,

private GoogleMap mMapView;

public void onActivityCreated(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onActivityCreated(savedInstanceState);
FragmentManager fm = getChildFragmentManager();
map = (SupportMapFragment) fm.findFragmentById(R.id.map);
if (map == null) {
map = SupportMapFragment.newInstance();
fm.beginTransaction().replace(R.id.map, map).commit();

// Zoom in, animating …我正在尝试创建一个我正在构建的应用程序从主要活动中获取搜索词,返回结果,然后使结果可以被点击,以便可以从每个结果中查看详细信息.我这样做是通过使用MainActivity,ResultsActivity和PlaceActivity,然后是ListFragmentClickable(扩展ListFragment).如果手机朝向纵向模式,则结果列表应该是可见的,只有在单击结果时才会查看详细信息.如果手机是横向的,则在选择项目时,应在列表右侧弹出详细信息窗口.
在运行时,我收到一个错误,上面写着"错误膨胀类片段".我不知道是什么导致它,我很乐意帮助摆脱它.
我的ListFragmentClickables由我的ResultsActivity调用,它位于:
public class ResultsActivity extends FragmentActivity implements ListFragmentClickable.OnItemSelectedListener{
private ArrayAdapter<String> mAdapter;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_results_view);
//Receive searchTerm from MainActivity
Intent intent = getIntent();
String searchTerm = intent.getStringExtra(MainActivity.SEARCH_TERM);
mAdapter = new ArrayAdapter<String>(this, R.layout.item_label_list);
FragmentManager fm = getSupportFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
FactualResponderFragment responder = (FactualResponderFragment) fm.findFragmentByTag("RESTResponder");
if (responder == null) {
responder = new FactualResponderFragment();
ft.add(responder, "RESTResponder");
}
Bundle bundle = new Bundle();
bundle.putString("search_term", searchTerm);
responder.setArguments(bundle);
ft.commit();
}
public ArrayAdapter<String> getArrayAdapter() {
return mAdapter;
} …我正试图在片段中显示来自Google Maps API V2的地图.我尝试使用SupportMapFragment,但我无法获得预期的输出.我也是这个平台的初学者!我真正想要的只是一种将Google Maps API V2 for Android中的地图放入片段中的方法.请分享您的想法和参考.
提前致谢 !
我在我的三个标签片段中添加了一个全屏地图片段.除了我在标签之间切换时遇到的问题,一切都很有效.
每次我从带有地图的片段切换到其他片段之一时,我会得到一个0.2秒的黑屏.对于使用地图片段滚动活动的问题,这似乎是一个类似的问题.
我已经尝试在其他人建议的地方添加透明视图以外的地图,但它没有帮助.
这是我的xml:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".ParkMapFragment">
<fragment
android:id="@+id/fullParkMap"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</FrameLayout>
这是我的代码:
public class ParkMapFragment extends Fragment {
public ParkMapFragment() {
// Required empty public constructor
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_map, container, false);
}
@Override
public void onStart(){
super.onStart();
getActivity().setTitle("Map");
}
@Override
public void onDestroyView() {
super.onDestroyView();
SupportMapFragment mapFragment = (SupportMapFragment) getFragmentManager().findFragmentById(R.id.fullParkMap);
if (mapFragment != null) {
getFragmentManager().beginTransaction().remove(mapFragment).commit();

我在stackoverflow上发现了很多类似的问题,但他们的解决方案在我的情况下不起作用.它们与onSaveInstanceState方法和支持库特别相关.
我Activity在一个事件上运行此代码:
MyDialogFragment.showMyDialog(name, this, this);
name参数是String对象.第二个参数(this)是正则Activity类对象,第三个参数(也this)是简单接口.我Activity实现了这个接口.showMyDialog()当然是静态方法.这是它的身体:
MyDialogFragment fragment = new MyDialogFragment(listener, "Hello " + name);
fragment.show(activity.getFragmentManager(), "myDialog");
这在第一次尝试时效果很好.但是在第二天我得到了这个例外:
