我正在实现一个照片查看器,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添加膨胀的视图.在充气视图中,有一个允许用户切换图像的ViewPager.我收到错误“java.lang.IllegalArgumentException：找不到id的视图”
我目前的方法是向WindowManager添加膨胀的视图.在充气视图中,有一个允许用户切换图像的ViewPager.我收到错误“java.lang.IllegalArgumentException：找不到id的视图”
以下是详细信息(视图在setActivity方法中为openPhoto方法中的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();
}
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);
}
}
这里是viewPager视图的布局：
