ImageView XML へのフラグメント内で OnClick を設定する際に問題が発生しています。

アプリの実行中にスワイプできる画像を表示するために、内部に ImageView と進行状況バーを表示する ViewPager があります。

ユーザーが現在表示されている画像をクリックすると、トーストメッセージが表示されるようにすることを目指しています。

私が抱えている問題は、現在表示されている画像をクリックしても何も起こらないことです。

どんな助けでも素晴らしいでしょう、ありがとう。

ImageView と進行状況バーを制御するフラグメント化する XML:

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >

<ProgressBar
    style="?android:attr/progressBarStyleLarge"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center" />

RecyclingImageView
    android:id="@+id/imageView"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:contentDescription="@string/imageview_description" />

</FrameLayout>

ImageView を制御するフラグメント:

public class ImageDetailFragment extends Fragment {
private static final String IMAGE_DATA_EXTRA = "extra_image_data";
private String mImageUrl;
private RecyclingImageView mImageView;
private ImageFetcher mImageFetcher;

public static ImageDetailFragment newInstance(String imageUrl) {
    final ImageDetailFragment f = new ImageDetailFragment();

    final Bundle args = new Bundle();
    args.putString(IMAGE_DATA_EXTRA, imageUrl);
    f.setArguments(args);

    return f;
}

public ImageDetailFragment() {
}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    mImageUrl = getArguments() != null ? getArguments().getString(
            IMAGE_DATA_EXTRA) : null;
}



@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
    Bundle savedInstanceState) {

     final View v = inflater.inflate(R.layout.image_detail_fragment,
        container, false);

     mImageView = (RecyclingImageView) v.findViewById(R.id.imageView);
      mImageView.setOnClickListener(new OnClickListener() {
       @Override
       public void onClick(View arg0) {
             Toast.makeText(getActivity(), "Cilcked..",Toast.LENGTH_SHORT).show();
     }
  });

return v;
 }

@Override
public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);

    if (Batmanark.class.isInstance(getActivity())) {
        mImageFetcher = ((Batmanark) getActivity()).getImageFetcher();
        mImageFetcher.loadImage(mImageUrl, mImageView);
    }

    // Pass clicks on the ImageView to the parent activity to handle
    if (OnClickListener.class.isInstance(getActivity())
            && Utils.hasHoneycomb()) {
        mImageView.setOnClickListener((OnClickListener) getActivity());
    }
}

@Override
public void onDestroy() {
    super.onDestroy();
    if (mImageView != null) {
        // Cancel any pending image work
        ImageWorker.cancelWork(mImageView);
        mImageView.setImageDrawable(null);
    }
}
}

ViewPager XML:
