Question

我已将pinchzoom.jar库添加到我的项目中以允许捏合和缩放图像。并添加了以下代码 -

try {
                    usingSimpleImage(imageView);
                }
                catch(Exception e) {
                }

 public void usingSimpleImage (ImageView imageView){
        try {
            ImageAttacher mAttacher = new ImageAttacher(imageView);
            // ImageAttacher.MAX_ZOOM = 2.0f; // Double the current Size
            //  ImageAttacher.MIN_ZOOM = 0.5f; // Half the current Size
            MatrixChangeListener mMaListener = new MatrixChangeListener();
            mAttacher.setOnMatrixChangeListener(mMaListener);
            PhotoTapListener mPhotoTap = new PhotoTapListener();
            mAttacher.setOnPhotoTapListener(mPhotoTap);
        }
        catch(Exception e)
        {
            System.out.println("exception");
        }
    }


    private class PhotoTapListener implements OnPhotoTapListener {

        @Override
        public void onPhotoTap(View view, float x, float y) {
        }
    }

    private class MatrixChangeListener implements OnMatrixChangedListener {

        @Override
        public void onMatrixChanged(RectF rect) {

        }
    }

当我快速捏合和缩放并且我的应用程序崩溃时，我有以下异常 -

可能面临与https://github.com/chrisbanes/PhotoView/issues/4相同的问题。

解决方法是尝试捕获错误：

@Override
public boolean onInterceptTouchEvent(MotionEvent event) {
    try {
        return super.onInterceptTouchEvent(event);
    } catch (IllegalArgumentException e) {
        e.printStackTrace();
        return false;
    }
}

IllegalArgumentException：当我对图像进行pinchzoom时，pointerIndex超出范围
