【中文标题】WindowManager 添加的视图上的 ViewPager 获取“java.lang.IllegalArgumentException：找不到 id 的视图”【英文标题】：ViewPager on a view added by WindowManager getting "java.lang.IllegalArgumentException: No view found for id" 【发布时间】：2015-01-14 06:50:33 【问题描述】：我正在实现一个照片查看器，它允许用户从缩略图以全屏模式查看照片。
我目前的方法是向WindowManager 添加膨胀视图。在膨胀视图中，有一个ViewPager 允许用户切换图像。我收到错误“java.lang.IllegalArgumentException: No view found for id”
这里是细节（视图在 setActivity 方法中膨胀，并在 openPhoto 方法中为 viewPager 设置适配器）：
public class PhotoViewer
private static final String TAG = "PhotoViewer";
private Activity parentActivity;
private FrameLayoutTouchListener windowView;
private RelativeLayout containerView;
private WindowManager.LayoutParams windowLayoutParams;
private PhotoViewerAdapter photoAdapter;
private ViewPager viewPager;
public PhotoViewer()
super();
private static volatile PhotoViewer Instance = null;
/*inflate view here*/
public void setParentActivity(Activity activity)
if (parentActivity == activity)
return;
parentActivity = activity;
windowView = new FrameLayout(activity);
containerView = (RelativeLayout) LayoutInflater.from(activity)
.inflate(R.layout.fragment_photo_viewer, null);
containerView.setFocusable(false);
windowView.addView(containerView);
windowLayoutParams = new WindowManager.LayoutParams();
windowLayoutParams.height = WindowManager.LayoutParams.MATCH_PARENT;
windowLayoutParams.format = PixelFormat.TRANSLUCENT;
windowLayoutParams.width = WindowManager.LayoutParams.MATCH_PARENT;
windowLayoutParams.gravity = Gravity.TOP;
windowLayoutParams.type = WindowManager.LayoutParams.LAST_APPLICATION_WINDOW;
windowLayoutParams.flags = WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE;
viewPager = (ViewPager) containerView.findViewById(R.id.photo_viewer_view_pager);
/*set data and adapter for viewPager here*/
public void openPhoto (PhotoSupporter photoSupporter, int position)
try
if (windowView.getParent() != null)
WindowManager wm = (WindowManager) parentActivity.getSystemService(Context.WINDOW_SERVICE);
wm.removeView(windowView);
catch (Exception e)
Log.v(TAG, e.getMessage());
WindowManager wm = (WindowManager) parentActivity.getSystemService(Context.WINDOW_SERVICE);
wm.addView(windowView, windowLayoutParams);
this.photoSupporter = photoSupporter;
photoAdapter = new PhotoViewerAdapter(((FragmentActivity) parentActivity).getSupportFragmentManager(), photoSupporter);
viewPager.storeAdapter(photoAdapter);
viewPager.setCurrentItem(position);
/**
* Larger PhotoView
*
*
* **/
public static class PhotoViewerAdapter extends FragmentStatePagerAdapter
private PhotoSupporter photoSupporter;
public PhotoViewerAdapter(FragmentManager fm, PhotoSupporter photoSupporter)
super(fm);
this.photoSupporter = photoSupporter;
@Override
public Fragment getItem(int position)
String src = null;
// get photo src
return PhotoViewFragment.newInstance(src);
@Override
public int getCount()
Log.w(TAG, "size in adapter: " + photoSupporter.getSize());
return photoSupporter.getSize();
public static class PhotoViewFragment extends Fragment
private String imagePath;
public PhotoViewFragment()
public static PhotoViewFragment newInstance(String imagePath)
PhotoViewFragment previewFragment = new PhotoViewFragment();
// put data
Bundle bundle = new Bundle();
bundle.putString("IMAGE_PATH",
imagePath);
previewFragment.setArguments(bundle);
return previewFragment;
/**
* When creating, retrieve this instance's number from its arguments.
*/
@Override
public void onCreate(Bundle savedInstanceState)
super.onCreate(savedInstanceState);
imagePath = getArguments() != null ? getArguments().getString(
"IMAGE_PATH") : "";
Log.d("onCreate", imagePath);
/**
* The Fragment's UI is just a simple text view showing its instance
* number.
*/
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState)
ImageView imageView = new ImageView(getActivity());
LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams
(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT);
imageView.setLayoutParams(lp);
// set image by Picasso
Picasso picassoInstance = Picasso.with(getActivity());
picassoInstance.setIndicatorsEnabled(true);
picassoInstance.load(new File(imagePath))
.error(R.drawable.ic_picture_placeholder_light2)
.fit()
.centerInside()
.into(imageView);
return imageView;
这里是调用 PhotoViewer 方法的地方：
public class PhotosFragment extends Fragment implements PhotoSupporter
/*
....
*/
@Override
public void onViewCreated(View view, Bundle savedInstanceState)
super.onViewCreated(view, savedInstanceState);
showLoading();
photosGridview = (GridView) findViewById(R.id.group_photos_gridview);
if (listPhotos == null)
listPhotos = new ArrayList<Photo>();
photoListAdapter = new PhotoListAdapter(listPhotos, getActivity());
photosGridview.setAdapter(photoListAdapter);
photosGridview.setOnItemClickListener(new OnItemClickListener()
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id)
PhotoViewer.getInstance().setParentActivity(getActivity());
PhotoViewer.getInstance().openPhoto(PhotosFragment.this, position);
);
@Override
public int getSize()
return listPhotos == null ? 0 : listPhotos.size();
@Override
public Photo getPhotoItem(int position)
return listPhotos.get(position);
这是包含 viewPager 的视图布局：
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_
android:layout_
android:orientation="vertical" >
<android.support.v4.view.ViewPager
android:id="@+id/photo_viewer_view_pager"
android:layout_
android:layout_
android:background="@color/dark_background" >
</android.support.v4.view.ViewPager>
这里是logcat：

这个问题有什么解决办法吗？非常感谢你们！
【问题讨论】：
发布带有问题的 logcat 结果 @ρяσѕρєяK 你能看一下更新后的问题吗 【参考方案1】：我认为这是因为您直接通过 WindowManager 添加 ViewPager。这样做意味着它不会成为正常 Activity 视图层次结构的一部分（即装饰视图的子视图）。 Activity.findViewById（使用装饰视图作为根遍历视图）将无法找到您的 ViewPager。
ViewPager 适配器创建 Fragments 并使用 ViewPager (id) 作为容器。在创建 Fragment 时，Android 通过Activity.findViewById 查找此容器，但无法找到它并因此引发此异常。
听起来您想要某种显示在缩略图网格顶部的视图。您可以使用 properly styled Dialog(Fragment) 来实现此目的。实施该观点的具体细节最好作为一个单独的问题提出。
【讨论】：
我在挖掘到android源码后也发现了。谢谢。 嗨@antonyt，我刚刚将我的实现更改为您的建议，但我遇到了一个非常棘手的问题。请您看一下：***.com/questions/27980543/…【参考方案2】：我认为你只是错过了一个小错误。而不是这个。
viewPager = (ViewPager) containerView.findViewById(R.id.photo_viewer_view_pager);
做
viewPager = (ViewPager) containerView.findViewById(R.id.photo_viewer_viewpager);
我认为您为 viewpager 使用了错误的 ID。希望它能解决你的问题。
【讨论】：
对不起，这是我在 *** 上的错字。你能看看更新后的问题吗？【参考方案3】：我认为你在 findviewById() 之后在 setParenActivity() 中膨胀了视图，这就是它没有获得视图的原因。
【讨论】：
不，我根本没有使用 findViewById。以上是关于WindowManager 添加的视图上的 ViewPager 获取“java.lang.IllegalArgumentException：找不到 id 的视图”的主要内容，如果未能解决你的问题，请参考以下文章
