Android Webview scroll to bottom programmatically (Kotlin)












0















I am trying to reach bottom of a Webview.
I am getting the height of Webview inside onPageFinished() method by,



override fun onPageFinished(view: WebView?, url: String?) {



                Log.d("webview_total_height", "height " + view!!.contentHeight)

                height = view!!.contentHeight

            }


And on button click I am trying to reach to bottom by,



wvMain.scrollTo(0, height)


But it's scrolling to somewhere middle of webview, not reaching bottom



How will I reach to the bottom of webview?

  • If you can extend WebView try overriding and exposing protected method computeVerticalScrollRange().

Just replace



wvMain.scrollTo(0, height)


By



wvMain.scrollTo(0, height * getResources().getDisplayMetrics().density.toInt())


By this you will get actual height of WebView in pixels as per device screen density



I guess you will get your desired result.

count number of partitions of a set with n elements into k subsets

Image
up vote 6 down vote favorite 1 This program is for count number of partitions of a set with n elements into k subsets I am confusing here return k*countP(n-1, k) + countP(n-1, k-1); can some one explain what is happening here? why we are multiplying with k? NOTE->I know this is not the best way to calculate number of partitions that would be DP // A C++ program to count number of partitions // of a set with n elements into k subsets #include<iostream> using namespace std; // Returns count of different partitions of n // elements in k subsets int countP(int n, int k) { // Base cases if (n == 0 || k == 0 || k > n) return 0; if (k == 1 || k == n) return 1; // S(n+1, k) = k*S(n, k) + S(n, k-1) return k*countP(n-1, k) + countP(n-1, k-1); } // Driver program int ma

A CLEAN and SIMPLE way to add appendices to Table of Contents and bookmarks

Image
0 I found a lot of questions abount appendices and ToC. Many users want appendices to be grouped in an Appendix part, however some problems arise with ToC, hyperref, PDF viewer bookmarks, and so on. There are different solutions which require extra packages, command patching and other extra code, however none of them satisfies me. I almost found an easy way to accomplish a good result, where appendices are added to bookmarks in the right way and hyperref links point to the right page. However, the number of the "Appendix" part page is wrong (it's the number of appendix A). Is there any EASY way to fix that? This is a MWE: documentclass{book} usepackage[nottoc,notlot,notlof]{tocbibind} usepackage{hyperref} begin{document} frontmatter tableofcontents mainmatter part{First} chapter{
