1 问题

第三方开源框架用了这个第三方开源框架（SubsamplingScaleImageView）加载长图，但是源代码在有些手机上面不能进行放缩。

    private void displayLongPic(Uri uri, SubsamplingScaleImageView longImg) {longImg.setQuickScaleEnabled(true);longImg.setZoomEnabled(true);longImg.setPanEnabled(true);longImg.setDoubleTapZoomDuration(100);longImg.setMinimumScaleType(SubsamplingScaleImageView.SCALE_TYPE_CENTER_CROP);longImg.setDoubleTapZoomDpi(SubsamplingScaleImageView.ZOOM_FOCUS_CENTER);longImg.setImage(ImageSource.uri(uri), new ImageViewState(0, new PointF(0, 0), 0));}

 

 

 

 

 

 

 

 

 

2 解决办法

把部分设置全部去掉，坑死我了，直接一行代码就行。

   private void displayLongPic(Uri uri, SubsamplingScaleImageView longImg) {longImg.setImage(ImageSource.uri(uri), new ImageViewState(0, new PointF(0, 0), 0));}
