android - TouchImageView leaves trails -
i using touchimageview zoom in/out feature on imageview. though works, when zoom out not clearing previous zoomed-in causing trails around image, in image shown below. please see wavy @ top , bottom occurred when zoomed out leaving trails of zoomed image.
i tried invaldiate() before matrix.posttranslate, didn't solve this. anyway zoom out work without leaving trail.
thank you.
