I have found a hack. Rotate your pdf by 180 degress and then add following line in your code

pdf_activity_read_quraan.rotation = 180F

where is pdf_activity_read_quraan is reference of com.github.barteksc.pdfviewer.PDFView

Try adding android:supportsRtl="true" in Application tag of the manifest file.

Possible workaround would be acquiring the scroll and force move like this :

mScrollView.postDelayed(new Runnable() {
    public void run() {
        scrollView.fullScroll(HorizontalScrollView.FOCUS_RIGHT); // or scrollTo
    }
}, 100L);
