使用ObjectAnimator旋转Gallery里面的图片，gallery的ItemClick无效

[akebrt]

代码如下：
adapter代码

public class GalleryBugAdapter extends BaseAdapter{

	private ArrayList<HashMap<String, String>> list;

	private Context mContext;

	private ImageView mImg;

	public Bitmap bitmap;

	private Gallery gallery;
	
	private int tag = 0;

	// rotate
	private int nowAngle = 0, toAngle = 0;

	private int w, h;

	public GalleryBugAdapter(ArrayList<HashMap<String, String>> list, Context context, Gallery gallery) {
		if (list != null) {
			this.list = list;
		} else {
			this.list = new ArrayList<HashMap<String, String>>();
		}
		this.mContext = context;
		this.gallery = gallery;
	}

	@Override
	public int getCount() {
		return list.size();
	}

	@Override
	public Object getItem(int position) {
		return list.get(position);
	}

	@Override
	public long getItemId(int position) {
		return position;
	}

	@Override
	public View getView(int position, View convertView, ViewGroup parent) {
		if (tag != position) {
			nowAngle = 0;
			toAngle = 0;
		}

		tag = position;
		mImg = new ImageView(mContext);

		// 父控件的宽高
		w = parent.getWidth();
		h = parent.getHeight();

		String path = list.get(position).get("list_img_path");
		Bitmap bitmap = getBitmap(path, w, h);

		mImg.setImageBitmap(bitmap);
		mImg.setTag(position);
		mImg.setFocusable(false);
		mImg.setClickable(false);
		mImg.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));

		return mImg;
	}

	private Bitmap getBitmap(String imgPath, int nWidth, int nHeight) {
		Bitmap bitmap = null;
		BitmapFactory.Options options = new BitmapFactory.Options();
		if (nWidth != 0 && nHeight != 0) {
			options.inJustDecodeBounds = true;
			bitmap = BitmapFactory.decodeFile(imgPath, options);
			if (options.outWidth <= nWidth && options.outHeight <= nHeight) {
				mImg.setScaleType(ScaleType.CENTER_INSIDE);
				return BitmapFactory.decodeFile(imgPath);
			}
			int hRatio = (int) Math.ceil(options.outHeight / (double) nHeight);
			int wRatio = (int) Math.ceil(options.outWidth / (double) nWidth);
			options.inSampleSize = (hRatio > wRatio) ? hRatio : wRatio;
			options.inJustDecodeBounds = false;
		}
		bitmap = BitmapFactory.decodeFile(imgPath, options);
		return bitmap;
	}

	public void Rotate(boolean flag, int angle) {
		mImg = (ImageView) gallery.findViewWithTag(tag);
		AnimatorSet aSet = new AnimatorSet();
		if (flag) {
			toAngle = (toAngle + 90) % 360;
		} else {
			toAngle = (toAngle - 90) % 360;
		}

		if (angle == 1) {
			toAngle = 0;
		}
		ObjectAnimator oAX = ObjectAnimator.ofFloat(mImg, "rotation", nowAngle, toAngle);
		nowAngle = toAngle;
		aSet.play(oAX);
		aSet.setDuration(0);
		aSet.start();
	}
}

控件属性

public void initGallery(int position, ArrayList<HashMap<String, String>> photoList) {

		if (layoutGallery == null) {
			layoutGallery = ((ViewStub) findViewById(R.id.photo_gallery)).inflate();
		}

		photoGallery = (Gallery) layoutGallery.findViewById(R.id.Gallery);

		adapter = new GalleryAdapter(photoList, this, photoGallery);
		photoGallery.setAdapter(adapter);
		photoGallery.setOnItemSelectedListener(new OnItemSelectedListener() {

			@Override
			public void onItemSelected(AdapterView<?> parent, View view, int item, long id) {
				Log.d("media", "dell-ItemSelected");
			}

			@Override
			public void onNothingSelected(AdapterView<?> parent) {

			}
		});

		photoGallery.setOnItemClickListener(new OnItemClickListener() {

			@Override
			public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
				Log.d("media", "dell-ItemClick");
			}
		});

		btnRotate1 = (Button) findViewById(R.id.btnRotate1);
		btnRotate2 = (Button) findViewById(R.id.btnRotate2);
		btnRotate1.setOnClickListener(new OnClickListener() {// 逆时针旋转90度

			@Override
			public void onClick(View v) {
				Log.e("PhotoRotate", "BUG-旋转后会让gallery的");
				adapter.Rotate(false, 0);
			}
		});
		btnRotate2.setOnClickListener(new OnClickListener() {// 顺时针旋转90度

			@Override
			public void onClick(View v) {
				adapter.Rotate(true, 0);
			}
		});
	}

如题，用以上代码旋转图片后 ，出现现象：
顺时针旋转90度，会让以图片为中心，第一象限的区域可以感应到点击事件，其余三个象限完全无效；
再旋转90度，让可以点击的区域也旋转90度，第四象限区域可以感应点击事件，其余三个象限区域点击无效；
然后再旋转，可点击区域转到第三象限。

逆时针旋转类似
当图片转回原始的角度，然后所有区域都可以点击了，这是怎么一回事？？？

有没有人遇到过这样的？
