android - How to center vector drawable in layer-list without scaling -


i attempting use vectordrawable in layerlist without scaling vector. example:

<layer-list>     <item android:drawable="@color/grid_item_activated"/>     <item android:gravity="center" android:drawable="@drawable/ic_check_white_48dp"/> </layer-list>

the drawable ic_check_white_48dp id defined as:

<vector xmlns:android="http://schemas.android.com/apk/res/android"         android:width="48dp"         android:height="48dp"         android:viewportwidth="24.0"         android:viewportheight="24.0">     <path         android:fillcolor="#ffffffff"         android:pathdata="m9,16.17l4.83,12l-1.42,1.41l9,19 21,7l-1.41,-1.41z"/> </vector>

the desired effect check icon centered in layer drawable, without scaling. issue is, layer-list above causes check icon scaled fit layer size.

i can produce desired effect if replace vector drawable pngs each density , modify layer-list such:

<layer-list>     <item android:drawable="@color/grid_item_activated"/>     <item>         <bitmap android:gravity="center" android:src="@drawable/ic_check_white_48dp"/>     </item> </layer-list>

is there way can using vectordrawable?

i ran same problem trying center vectors drawables on layered list.

i have workaround, not same works, need set size entire drawable , add padding vector item:

<?xml version="1.0" encoding="utf-8"?> <layer-list xmlns:android="http://schemas.android.com/apk/res/android">     <item>         <shape>             <size android:height="120dp" android:width="120dp"/>             <solid android:color="@color/grid_item_activated"/>         </shape>     </item>     <item android:top="24dp"           android:bottom="24dp"           android:left="24dp"           android:right="24dp"           android:drawable="@drawable/ic_check_white_48dp"/> </layer-list>

the size of shape above sets size of entire drawable, 120dp in example, padding on second item, 24dp in example, centers vector image.

its not same using gravity="center" working way of using vectors in api 21 , 22.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } &l
