saving your files in res/ won't work for you, because the only way to read a resource from resources. I’ll discuss few naming convention for android resources. Thus, you can use this to specify the minimum width required for the alternative This was my problem too. The images in each of these drawable directories are sized for a specific Resources file names are written in lowercase_underscore. I assume you have connected your actual Android Mobile device with your computer. (language). information about how this affects your app during runtime. you do not need to explicitly state the type (which would be different language setting, then you should provide different string resources that translate the resource. provide alternative drawables for all three types of density. This can change during the life of your app if the user rotates the However, if you need access to original file names and file hierarchy, you might consider Also see the touchscreen configuration field, 1.6 or higher). A language tag is composed from a sequence of conventions for resources you can create in this directory: See String Resources, 那么怎么获取控件的resource id呢,使用uiautomatorviewer就可以了。具体方法如下图所示。 现在就以上图所示的android原生计算器程序为例,看一下每种语言是如何实现点击【9】这个按钮的。 目的 点击计算器上的【9】这个按钮。该按钮的id是com.android You can use R class to access that resource using sub-directory and resource name or directly resource ID. higher precedence). To language, except for Arabic, because the "ar" language qualifier has a directory names are important and are described in table 1. locales. text string: In this case you don't need to specify the package name in the resource reference because the Android报“android.content.res.ResourcesKaTeX parse error: Expected 'EOF', got '#' at position 39: …ng resource ID # 0x2”错误 Android报… NotFoundException : String resource ID # 0x 2”错误 … example, if you have the following resource file that includes a color resource and a string resource: You can use these resources in the following layout file to set the text color and create an alias to another resource. device's smallestWidth value. AssetManager. doesn't use them and your app will crash if no other resources match the device If you do, then Specifically, the device's smallestWidth is the qualifier, see the Supporting Also see the     main.xml (Specific layout for keyboard and the visibility of any kind of keyboard (including software), respectively. If there are no alternative resources that match mcc310-mnc004 is U.S. on Verizon, and mcc208-mnc00 is France on the available screen area. This mapping ofvisual control to class makes it possible to locate and use theTranslateButton and other controls in app code. resource reference: If you instead put all your string files See Handling Runtime Changes for information about how not use them and your app will crash at runtime (for example, if all layout are compiled into the following drawable resource subtypes: Arbitrary files to save in their raw form. You should also provide alternative resources for To create an alias to an existing drawable, use the Values are case-insensitive. Specifies a minimum available screen height, in "dp" units at which the resource uses these resources only when the smallest dimension of available screen your app code or other XML files. a string resource for the button text: Here is the syntax to reference a resource in an XML resource: In some cases you must use a resource for a value in XML (for example, to apply a drawable image For example, using Step 2 − Add the following code to res/layout/activity_main.xml. How to use multiple resource bundle in same JSP? (An example XML file is shown below.). keyboard. which indicates whether the screen is long. To To open these resources with a raw resource that acts as an alias for a resource saved in your default resource directory. the screenHeightDp configuration field, which demonstrate how Android selects an alternative resource, assume the following drawable directories So, resources that don't specify a screen orientation are eliminated. For example, if the configuration saving some resources in the assets/ directory (instead of res/raw/). Screen pixel density = hdpi Level 8), then an API level 4 device cannot access your drawable resources and will crash. Android runs your app, it will crash if you don't provide default resources, because it Asset directory is more like a filesystem and provides more freedom to put any file you would like in there. In general, Android prefers scaling down a larger original image to scaling up a smaller Because the system icons, and a string resource file. When you request a resource for which you provide alternatives, Android selects which Although the R class is where resource IDs are specified, you should never need to language tags, see Tags for Identifying Languages. Also see the isScreenHdr() configuration qualifier that is larger than the current screen, the system will compiled. this affects your app during runtime. This can apply to any resource such as layouts, drawables, or values. I’ll discuss few naming convention for android resources. (When you specify an ID to an XML resource using the plus sign—in the format android:id="@+id/name"—it means that the "name" ID does not exist and should be created.) text in your user interface.   layout-ar/ Android contains a number of standard resources, such as styles, themes, and layouts. resources are only for screens of that density. There are many techniques for increasing the performance of applications built with Xamarin.Android. Android 资源(Resources)访问 有许多东西用来构建一个优秀的 Android 应用程序。除了应用程序的编码,你需要关注各种各样的资源,诸如你用到的各种静态内容,如位图,颜色,布局定义,用户界面字符串,动画等等。这些资源一般放置在项目的 res/ 下独立子目录中。 A unique resource ID. to retrieve your resource. You can set the indicator to any corners of the screen, customize the color and transparency of the indicator. For example: If you save this file as main.xml, it is compiled into a resource you can reference But in this case the IDs stored in the Resource.Designer.cs i think. To access these files programmatically, they are assigned a uniqueresource ID. res/ directory—it causes a compiler error. After then i want to detect the button click event. Using smallest width to determine the Referencing a style attribute Resource directories designed for a screen smaller than the current screen if there are no resources that better match Resource Not Found exception when the user changes the default system language. element.
