android - Browser's webpage able to zoom in and zoom out -


i developing android application requires open url link in web browser zoom in , zoom out control (i.e, chrome)
zoom in , zoom out facility found 1 solution want set zoom in , zoom out functionality programmatically.

i not want use android webview load webpages.

try {         intent myintent = new intent(intent.action_view, uri.parse("https://www.mds-foundation.org/mdsmanager/help"));         startactivity(myintent); } catch (activitynotfoundexception e) {        toast.maketext(mainactivity.this, "no application can handle request. please install web browser",  toast.length_long).show();        e.printstacktrace(); }

you cannot set zoom level while using intent intent.action_view. solution referring handling zoom level inside app only. not possible firing intent.

if want use android webview can this

public class mybrowser extends activity {     @override    public void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_layout);      string loadurl = "https://stackoverflow.com/";     int scale = 60; //scale percent of zoom level want      webview webview = (webview) findviewbyid(r.id.webview);      webview.getsettings().setloadwithoverviewmode(true);     webview.getsettings().setusewideviewport(true);     webview.setinitialscale(scale);      try {         webview.loadurl(loadurl);     } catch (exception e) {         e.printstacktrace();     }   } }

in layout file can define webview

<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent">      <webview     android:id="@+id/webview"     android:layout_width="match_parent"     android:layout_height="match_parent"></webview>  </linearlayout>

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
