android - 同时点击两张Subsampling scale图片会导致Android崩溃

Question

点击两个子采样比例 ImageView 后...当我同时点击它们时，出现此错误:

布局:

<FrameLayout
    android:id="@+id/idContainer"
    android:layout_width="match_parent"
    android:padding="16dp"
    android:layout_height="match_parent" >
    <com.davemorrissey.labs.subscaleview.SubsamplingScaleImageView
        android:id="@+id/idImage"
        android:background="@color/gsd_bg_darkest"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="center" />

    <ProgressBar
        android:id="@+id/idProgress"
        style="?android:attr/progressBarStyle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center" />
</FrameLayout>

代码:

// uri is a string with the URL
// the view, is the view where are the images. The setBusy will delete the spinner from it


private SubsamplingScaleImageView.OnImageEventListener createLoadingListener(final View side){
        return new SubsamplingScaleImageView.OnImageEventListener() {
            @Override
            public void onReady() {

            }

            @Override
            public void onImageLoaded() {
                setBusy(side, false);
            }

            @Override
            public void onPreviewLoadError(Exception e) {

            }

            @Override
            public void onImageLoadError(Exception e) {

            }

            @Override
            public void onTileLoadError(Exception e) {

            }
        };
    }

photoL = (SubsamplingScaleImageView) sideLeft.findViewById(R.id.idImage);
photoR = (SubsamplingScaleImageView) sideRight.findViewById(R.id.idImage);

photoL.setImage(ImageSource.uri(uri));
photoL.setOnImageEventListener(createLoadingListener(sideLeft));

我是否在 Android 代码中发现了错误，或者我应该怎么做才能找出真正的问题所在？非常感谢任何提示(也只是为了澄清问题)。

这是图书馆的一个错误。评论这一行解决了问题:
