由 房东的猫 提交于 2019-11-27 05:29:23
问题 Based on here on XML Attributes section I specify following in my dimens.xml : <dimen name="match_parent">-1dp</dimen> <dimen name="main_left_menu_user_account_width">@dimen/match_parent</dimen> <dimen name="main_left_menu_user_account_height">@dimen/match_parent</dimen> Then I use the both dimensions in my layout: <ImageView android:id="@+id/userAccountImage" android:background="@drawable/user_account" android:layout_width="@dimen/main_left_menu_user_account_width" android:layout_height="

How do I set the size of the visible area of a form, minus heading and borders?

由 不羁岁月 提交于 2019-11-27 04:05:54
问题 I would like to set my form to be exactly 300*300 excluding heading and borders. If I use Size property, it does include these values. Is there any way how to do it? 回答1: You have two options, as follows: To remove heading and borders from a Form, disable the Form's FormBorderStyle property. Set the interior of the form with the ClientSize property, as follows: this.ClientSize = new Size(300, 300); 回答2: Why not just factor in the size of the border and the title bar? int BorderWidth = (this

How to get screen's physical size (i.e. in inches)?

由 只愿长相守 提交于 2019-11-27 03:13:47
问题 I'm trying to figure out how to get the physical dimensions of a device's screen via Javascript. So far, my conclusion is that it's currently impossible, but I hope someone can prove me wrong :). So far I have tried to get this information by finding the device's DPI, but it seems there is no way to get the correct value here, as all devices I have tested (some HDPI & XHDPI Android devices, an iPhone4S, an iPad 2 and an iPad 3) report 96DPI. The first method of obtaining the DPI I tried is

Measuring text width/height without rendering

由 寵の児 提交于 2019-11-26 23:01:48
问题 Is there any way to get an estimate for text width without rendering the actual elements? Something like canvas TextMetrics? Case: I need to estimate element heights for ReactList. To do that I'd need to know roughly how much space the text elements will need (or how many lines will they span). eg. render(){ return <div><SomeComponentWithKnownDims/><p>{this.props.someText}</p></div>; } If I knew how wide someText would be rendered into one line and how long the line would be, I could easily

How to deep copy 2 dimensional array (different row sizes)

由 一个人想着一个人 提交于 2019-11-26 21:22:57
问题 This is my first question in a community like this, so my format in question may not be very good sorry for that in the first place. Now that my problem is I want to deep copy a 2 dimension array in Java. It is pretty easy when doin it in 1 dimension or even 2 dimension array with fixed size of rows and columns. My main problem is I cannot make an initialization for the second array I try to copy such as: int[][] copyArray = new int[row][column] Because the row size is not fixed and changes

Possible Duplicate: Cluster one-dimensional data optimally? So let's say I have an array like this: [1,1,2,3,10,11,13,67,71] Is there a convenient way to partition the array into something like this? [[1,1,2,3],[10,11,13],[67,71]] I looked through similar questions yet most people suggested using k-means to cluster points, like scipy , which is quite confusing to use for a beginner like me. Also I think that k-means is more suitable for two or more dimensional clustering right? Are there any ways to partition an array of N numbers to many partitions/clustering depending on the numbers?

Difference between android dimension: pt and dp

由 对着背影说爱祢 提交于 2019-11-26 11:52:16
问题 The documentation says that 160 dp (density-independent) equals 1 inch. And 72 pt is also 1 inch. So I don\'t see why android define a dp measurement while it seems to work the same as points. Can anybody explain that? Why should I use dp if I can use pt? 回答1: The Android documentation used to incorrectly state that 160 dp always equals 1 inch regardless of screen density. This was reported as a bug which was accepted and the documentation updated. From the updated documentation: 160 dp will

Load dimension value from res/values/dimension.xml from source code

由 社会主义新天地 提交于 2019-11-26 06:12:50
问题 I\'d like to load the value as it is. I have two dimension.xml files, one in /res/values/dimension.xml and the other one in /res/values-sw360dp/dimension.xml . From source code I\'d like to do something like getResources().getDimension(R.dimen.tutorial_cross_marginTop); This works but the value I get is multiplied times the screen density factor (1.5 for hdpi, 2.0 for xhdpi, etc). I also tried to do getResources().getString(R.dimen.tutorial_cross_marginTop); This would work in principle but I

问题 What is the difference between Android units of measure? px dip dp sp 回答1: From the Android Developer Documentation: px Pixels - corresponds to actual pixels on the screen. in Inches - based on the physical size of the screen. 1 Inch = 2.54 centimeters mm Millimeters - based on the physical size of the screen. pt Points - 1/72 of an inch based on the physical size of the screen. dp or dip Density -independent Pixels - an abstract unit that is based on the physical density of the screen.
