问题描述

我在执行一个照片浏览器，允许用户从缩略图查看全屏模式下的照片。 我目前的做法是将膨胀以窗口管理器。在膨胀的观点，有一个 ViewPager 允许用户切换图像。而我得到的错误java.lang.IllegalArgumentException：如果没有查看发现号

I am implementing a photo viewer which allow user to view photos in full-screen mode from a thumbnail. My current approach is adding inflated view to WindowManager. In the inflated view, there is a ViewPager allowing user switch images. And I got error "java.lang.IllegalArgumentException: No view found for id"

下面是详细信息（视图是充气的setActivity方法和viewPager在openPhoto方法设置适配器）：

Here is the details (a view is inflated in setActivity method and setting adapter for viewPager in openPhoto method):

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;
    }

}


}

和这里是哪里PhotoViewer的方​​法被称为：

and here is where PhotoViewer's method is called: 

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);
}
}

和这里认为contaning viewPager的布局：

and here is layout of the view contaning viewPager:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >

<android.support.v4.view.ViewPager
    android:id="@+id/photo_viewer_view_pager"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/dark_background" >
</android.support.v4.view.ViewPager>

下面是logcat的：

对于这个问题的任何解决方案？谢谢你们这么多！

Any solution for this problem? Thank you guys so much!

推荐答案

我想这是因为你直接通过窗口管理器，将您ViewPager。这样做意味着它不会是正常的活动视图层次结构（装饰观点，即一个孩子）的一部分。 Activity.findViewById （横穿使用的装饰视图为根视图）将无法找到您的ViewPager。

I think this is because you are adding your ViewPager directly via the WindowManager. Doing so means that it won't be part of the normal Activity view hierarchy (i.e. a child of the decor view). Activity.findViewById (which traverses views using the decor view as the root) won't be able to locate your ViewPager.

的ViewPager适配器创建片段并使用ViewPager（ID）作为容器。当创建一个片段，机器人通过 Activity.findViewById 查找这个容器，但将无法找到它，并因此引发此异常。

The ViewPager adapter creates Fragments and uses the ViewPager (id) as the container. When creating a Fragment, Android looks for this container via Activity.findViewById, but won't be able to find it and so throws this exception.

这听起来像你想的某种观点，即在格缩览图的顶部出现。你可以只用一个正确称呼对话框（片段）来实现这一目标。实施这个观点的细节将最好地摆在作为一个单独的问题。

It sounds like you want some kind of view that appears on top of the thumbnail grid. You could just use a properly styled Dialog(Fragment) to achieve this. The specifics of implementing that view would best be posed as a separate question.
