java - Scaling drawable resources -

-

i have done image editing of application want make fit every device scaling them different sizes. have found site put image scales different screen densities when put in project not adapt screen.

here's code:

<?xml version="1.0" encoding="utf-8"?> <relativelayout 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" android:paddingleft="@dimen/activity_horizontal_margin"     android:paddingright="@dimen/activity_horizontal_margin"     android:paddingtop="@dimen/activity_vertical_margin"     android:paddingbottom="@dimen/activity_vertical_margin" tools:context=".mainactivity"     android:background="@drawable/backgroundapp"     android:orientation="vertical">       <imagebutton         android:id="@+id/btnswitch"         android:layout_width="105dp"         android:layout_height="105dp"         android:src="@drawable/poweroffline"         android:background="@null"         android:layout_alignparenttop="true"         android:layout_centerhorizontal="true"         android:layout_margintop="65dp" />      <imagebutton         android:id="@+id/flashblinkbutton"         android:layout_width="75dp"         android:layout_height="75dp"         android:src="@drawable/blinkoffline"         android:background="@null"         android:layout_gravity="center_horizontal"         android:layout_below="@+id/btnswitch"         android:layout_centerhorizontal="true"         android:layout_margintop="40dp"/>      <imagebutton         android:layout_width="65dp"         android:layout_height="70dp"         android:id="@+id/alarmbutton"         android:src="@drawable/alarmoffline"         android:background="@null"         android:layout_centerhorizontal="true"         android:layout_below="@id/flashblinkbutton"         android:layout_margintop="30dp"/>  </relativelayout>

edit: automatically goes mdpi folder.

you can try set android:scaletype

for example :

 <imagebutton     android:id="@+id/flashblinkbutton"     android:layout_width="75dp"     android:layout_height="75dp"     android:src="@drawable/blinkoffline"     android:background="@null"     android:layout_gravity="center_horizontal"     android:layout_below="@+id/btnswitch"     android:layout_centerhorizontal="true"     android:layout_margintop="40dp"     android:scaletype="fitxy" />

you can see different variations in docs http://developer.android.com/reference/android/widget/imageview.scaletype.html

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
