values
-mcc310(sim卡运营商)
MCC and MNC Examples:
mcc310
mcc310-mnc004
mcc208-mnc00
etc.The mobile country code (MCC), optionally followed by mobile network code (MNC) from the SIM card in the device. For example, mcc310 is U.S. on any carrier,mcc310-mnc004 is U.S. on Verizon, and mcc208-mnc00 is France on Orange.
If the device uses a radio connection (GSM phone), the MCC and MNC values come from the SIM card.
You can also use the MCC alone (for example, to include country-specific legal resources in your application). If you need to specify based on the language only, then use the language and region qualifier instead (discussed next). If you decide to use the MCC and MNC qualifier, you should do so with care and test that it works as expected.
Also see the configuration fields mcc, and mnc, which indicate the current mobile country code and mobile network code, respectively.
-en(语言) {
Language and region Examples:
enfren-r
USfr-r
FRfr-rCA
etc.The language is defined by a two-letter ISO 639-1 language code, optionally followed by a two letter ISO 3166-1-alpha-2 region code (preceded by lowercase "r").
The codes are not case-sensitive; the r prefix is used to distinguish the region portion. You cannot specify a region alone.
This can change during the life of your application if the user changes his or her language in the system settings. See Handling Runtime Changes for information about how this can affect your application during runtime.
See Localization for a complete guide to localizing your application for other languages.
Also see the locale configuration field, which indicates the current locale.

Layout Direction ldrtl
ldltrThe layout direction of your application. ldrtl means "layout-direction-right-to-left". ldltr means "layout-direction-left-to-right" and is the default implicit value.
This can apply to any resource such as layouts, drawables, or values.
For example, if you want to provide some specific layout for the Arabic language and some generic layout for any other "right-to-left" language (like Persian or Hebrew) then you would have:
res/
layout/
main.xml (Default layout)
layout-ar/
main.xml (Specific layout for Arabic)
layout-ldrtl/
main.xml (Any "right-to-left" language, except
for Arabic, because the "ar" language qualifier
has a higher precedence.)
Note: To enable right-to-left layout features for your app, you must setsupportsRtl to "true" and set targetSdkVersion to 17 or higher.
Added in API level 17.
-sw320dp(屏幕最小宽度){
smallestWidth sw<N>dp
Examples:
sw320dp
sw600dp
sw720dp
etc.The fundamental size of a screen, as indicated by the shortest dimension of the available screen area. Specifically, the device's smallestWidth is the shortest of the screen's available height and width (you may also think of it as the "smallest possible width" for the screen). You can use this qualifier to ensure that, regardless of the screen's current orientation, your application has at least <N> dps of width available for its UI.
For example, if your layout requires that its smallest dimension of screen area be at least 600 dp at all times, then you can use this qualifer to create the layout resources, res/layout-sw600dp/. The system will use these resources only when the smallest dimension of available screen is at least 600dp, regardless of whether the 600dp side is the user-perceived height or width. The smallestWidth is a fixed screen size characteristic of the device; the device's smallestWidth does not change when the screen's orientation changes.
The smallestWidth of a device takes into account screen decorations and system UI. For example, if the device has some persistent UI elements on the screen that account for space along the axis of the smallestWidth, the system declares the smallestWidth to be smaller than the actual screen size, because those are screen pixels not available for your UI. Thus, the value you use should be the actual smallest dimension required by your layout (usually, this value is the "smallest width" that your layout supports, regardless of the screen's current orientation).
Some values you might use here for common screen sizes:
320, for devices with screen configurations such as:
240x320 ldpi (QVGA handset)
320x480 mdpi (handset)
480x800 hdpi (high density handset)
480, for screens such as 480x800 mdpi (tablet/handset).
600, for screens such as 600x1024 mdpi (7" tablet).
720, for screens such as 720x1280 mdpi (10" tablet).
When your application provides multiple resource directories with different values for the smallestWidth qualifier, the system uses the one closest to (without exceeding) the device's smallestWidth.
Added in API level 13.
Also see the android:requiresSmallestWidthDp attribute, which declares the minimum smallestWidth with which your application is compatible, and thesmallestScreenWidthDp configuration field, which holds the device's smallestWidth value.
For more information about designing for different screens and using this qualifier, see the Supporting Multiple Screens developer guide.
}
-w720dp(屏幕最佳宽度){
Available width w<N>dp
Examples:
w720dp
w1024dp
etc.Specifies a minimum available screen width, in dp units at which the resource should be used—defined by the <N> value. This configuration value will change when the orientation changes between landscape and portrait to match the current actual width.
When your application provides multiple resource directories with different values for this configuration, the system uses the one closest to (without exceeding) the device's current screen width. The value here takes into account screen decorations, so if the device has some persistent UI elements on the left or right edge of the display, it uses a value for the width that is smaller than the real screen size, accounting for these UI elements and reducing the application's available space.
Added in API level 13.
Also see the screenWidthDp configuration field, which holds the current screen width.
For more information about designing for different screens and using this qualifier, see the Supporting Multiple Screens developer guide.
}
-h720dp(屏幕最佳高度){
Available height h<N>dp
Examples:
h720dp h1024dp etc.Specifies a minimum available screen height, in "dp" units at which the resource should be used—defined by the <N> value. This configuration value will change when the orientation changes between landscape and portrait to match the current actual height.
When your application provides multiple resource directories with different values for this configuration, the system uses the one closest to (without exceeding) the device's current screen height. The value here takes into account screen decorations, so if the device has some persistent UI elements on the top or bottom edge of the display, it uses a value for the height that is smaller than the real screen size, accounting for these UI elements and reducing the application's available space. Screen decorations that are not fixed (such as a phone status bar that can be hidden when full screen) are not accounted for here, nor are window decorations like the title bar or action bar, so applications must be prepared to deal with a somewhat smaller space than they specify.
Added in API level 13.
Also see the screenHeightDp configuration field, which holds the current screen width.
For more information about designing for different screens and using this qualifier, see the Supporting Multiple Screens developer guide.

-large(屏幕尺寸){
small 小尺寸屏幕normal 正常大小的屏幕large 大尺寸屏幕xlarge 超大尺寸的屏幕
Screen size small normal large xlarge small: Screens that are of similar size to a low-density QVGA screen. The minimum layout size for a small screen is approximately 320x426 dp units. Examples are QVGA low density and VGA high density.
normal: Screens that are of similar size to a medium-density HVGA screen. The minimum layout size for a normal screen is approximately 320x470 dp units. Examples of such screens a WQVGA low density, HVGA medium density, WVGA high density.
large: Screens that are of similar size to a medium-density VGA screen. The minimum layout size for a large screen is approximately 480x640 dp units. Examples are VGA and WVGA medium density screens.
xlarge: Screens that are considerably larger than the traditional medium-density HVGA screen. The minimum layout size for an xlarge screen is approximately 720x960 dp units. In most cases, devices with extra large screens would be too large to carry in a pocket and would most likely be tablet-style devices. Added in API level 9.
Note: Using a size qualifier does not imply that the resources are only for screens of that size. If you do not provide alternative resources with qualifiers that better match the current device configuration, the system may use whichever resources are the best match.
Caution: If all your resources use a size qualifier that is larger than the current screen, the system will not use them and your application will crash at runtime (for example, if all layout resources are tagged with the xlarge qualifier, but the device is a normal-size screen).
Added in API level 4.
See Supporting Multiple Screens for more information.
Also see the screenLayout configuration field, which indicates whether the screen is small, normal, or large.
}
-long(屏幕长短边模式){
Screen aspect long notlong long: Long screens, such as WQVGA, WVGA, FWVGA
notlong: Not long screens, such as QVGA, HVGA, and VGA
Added in API level 4.
This is based purely on the aspect ratio of the screen (a "long" screen is wider). This is not related to the screen orientation.
Also see the screenLayout configuration field, which indicates whether the screen is long.
}
-port(当前屏幕横竖屏显示模式){
Screen orientation port land port: Device is in portrait orientation (vertical)
land: Device is in landscape orientation (horizontal)
This can change during the life of your application if the user rotates the screen. See Handling Runtime Changes for information about how this affects your application during runtime.
Also see the orientation configuration field, which indicates the current device orientation.
}
-car(dock模式){
UI mode car
desk
television
appliance
watchcar: Device is displaying in a car dock
desk: Device is displaying in a desk dock
television: Device is displaying on a television, providing a "ten foot" experience where its UI is on a large screen that the user is far away from, primarily oriented around DPAD or other non-pointer interaction
appliance: Device is serving as an appliance, with no display
watch: Device has a display and is worn on the wrist
Added in API level 8, television added in API 13, watch added in API 20.
For information about how your app can respond when the device is inserted into or removed from a dock, read Determining and Monitoring the Docking State and Type.
This can change during the life of your application if the user places the device in a dock. You can enable or disable some of these modes using UiModeManager. SeeHandling Runtime Changes for information about how this affects your application during runtime.}
-night(白天或夜晚){
Night mode night
notnightnight: Night time
notnight: Day time
Added in API level 8.
This can change during the life of your application if night mode is left in auto mode (default), in which case the mode changes based on the time of day. You can enable or disable this mode using UiModeManager. See Handling Runtime Changes for information about how this affects your application during runtime.
}
-ldpi(屏幕最佳dpi){
Screen pixel density (dpi) ldpi
mdpi
hdpi
xhdpi
nodpi
tvdpildpi: Low-density screens; approximately 120dpi.
mdpi: Medium-density (on traditional HVGA) screens; approximately 160dpi.
hdpi: High-density screens; approximately 240dpi.
xhdpi: Extra high-density screens; approximately 320dpi. Added in API Level 8
nodpi: This can be used for bitmap resources that you do not want to be scaled to match the device density.
tvdpi: Screens somewhere between mdpi and hdpi; approximately 213dpi. This is not considered a "primary" density group. It is mostly intended for televisions and most apps shouldn't need it—providing mdpi and hdpi resources is sufficient for most apps and the system will scale them as appropriate. This qualifier was introduced with API level 13.
There is a 3:4:6:8 scaling ratio between the four primary densities (ignoring the tvdpi density). So, a 9x9 bitmap in ldpi is 12x12 in mdpi, 18x18 in hdpi and 24x24 in xhdpi.
If you decide that your image resources don't look good enough on a television or other certain devices and want to try tvdpi resources, the scaling factor is 1.33*mdpi. For example, a 100px x 100px image for mdpi screens should be 133px x 133px for tvdpi.
Note: Using a density qualifier does not imply that the resources are only for screens of that density. If you do not provide alternative resources with qualifiers that better match the current device configuration, the system may use whichever resources are the best match.
See Supporting Multiple Screens for more information about how to handle different screen densities and how Android might scale your bitmaps to fit the current density.

-notouch(触摸屏模类型){
Touchscreen type notouch
fingernotouch: Device does not have a touchscreen.
finger: Device has a touchscreen that is intended to be used through direction interaction of the user's finger.
Also see the touchscreen configuration field, which indicates the type of touchscreen on the device.
}
-keysexposed(键盘类型){
Keyboard availability keysexposed
keyshidden
keyssoftkeysexposed: Device has a keyboard available. If the device has a software keyboard enabled (which is likely), this may be used even when the hardware keyboard is not exposed to the user, even if the device has no hardware keyboard. If no software keyboard is provided or it's disabled, then this is only used when a hardware keyboard is exposed.
keyshidden: Device has a hardware keyboard available but it is hidden and the device does not have a software keyboard enabled.
keyssoft: Device has a software keyboard enabled, whether it's visible or not.
If you provide keysexposed resources, but not keyssoft resources, the system uses the keysexposed resources regardless of whether a keyboard is visible, as long as the system has a software keyboard enabled.
This can change during the life of your application if the user opens a hardware keyboard. See Handling Runtime Changes for information about how this affects your application during runtime.
Also see the configuration fields hardKeyboardHidden and keyboardHidden, which indicate the visibility of a hardware keyboard and and the visibility of any kind of keyboard (including software), respectively.
