屏幕截图在很多方面都很有用，您可能已经在计算机上捕获了它们，尤其是当您的工作需要向人们解释时。通过这些屏幕截图，您可以轻松地向人们展示您的计算机屏幕的外观，您甚至可以添加指针以将人们的注意力吸引到屏幕截图的某些部分。
与您的台式计算机(desktop computer)一样，您的Android 设备(Android device)也提供截屏选项(the option to capture screenshots)。Android拥有这个功能已经很长时间了，并且在大多数基于这个操作系统(operating system)的设备上都可以使用。
实际上有多种方法可以在Android 设备(Android device)上截屏。根据您拥有的设备和偏好，您可以使用这些方法中的任何一种来捕获屏幕。
使用组合键在 Android 上截屏(Capture a Screenshot on Android Using a Key Combo)
在设备上捕获当前屏幕的一种便捷方法是使用组合键。几乎所有出厂的Android 设备(Android device)都有一个快捷键，按下该快捷键会拍摄当前屏幕的照片。
此组合键不是(combination isn)固定的，它因设备型号而异。例如，适用于OnePlus Android 设备(OnePlus Android device)的组合键可能不适用于三星设备(Samsung device)，即使两者运行相同的操作系统(operating system)。
以下是在各种Android(Android)设备上截屏所需的按键列表：
- Google Pixel：电源 + 降低音量
- 三星：(Samsung:)电源+降低音量
- LG：锁定+降低音量
- HTC：电源+家庭
- 一加：(OnePlus:)电源+降低音量
- 摩托罗拉：(Motorola:)电源 + 降低音量
- 索尼：(Sony:)电源 + 降低音量
如您所见，大多数设备使用电源和降低音量键组合(Power and Volume Down key combo)来捕获屏幕截图。如果您在列表中找不到适合您设备的组合，请使用这个通用的组合，它应该在大多数情况下都可以使用。
使用电源按钮在 Android 上截屏(Take a Screenshot on Android Using The Power Button)
在Android 设备(Android device)上，电源按钮(Power button)不仅仅是打开和关闭设备。它可以帮助您锁定您的设备、解锁您的设备、重新启动您的设备，甚至在您的设备上截取屏幕截图。
虽然大多数用户都知道电源按钮(Power button)的常用功能，但他们可能不知道该按钮也有屏幕捕获选项。这可以通过打开设备上的电源菜单(power menu)来访问。
这应该适用于大多数基于Android的手机和平板电脑
- 进入您要截屏的屏幕。
- 按住设备上的电源(Power)按钮。
- 屏幕上会弹出一个菜单，其中包含一些选项。点击屏幕截图(Screenshot)选项以捕获屏幕截图。
您当前Android 屏幕(Android screen)的屏幕截图将被捕获并保存在您Android 设备(Android device)上的默认屏幕截图文件夹中。尽管您在截取屏幕截图时看到了菜单，但此屏幕截图将没有电源菜单。(power menu)
然后，您可以使用设备上的文件管理器或图库应用(file manager or gallery app)找到此屏幕截图。
以无线方式在您的 Android 设备上截取屏幕截图(Grab a Screenshot On Your Android Device Wirelessly)
如果您要在截取屏幕截图后将屏幕截图从设备传输到计算机，则无需经历这些麻烦，因为您可以直接在计算机上截取屏幕截图。
有一个实用程序可让您在计算机上以无线方式截取Android 设备的屏幕截图。(Android device)它被称为AirDroid，如果您是该网站的常客（或者您曾经想将文件从 Android 传输到 Mac(transfer files from Android to Mac)或 PC），您可能听说过它。
这需要的只是您的两个设备都应该连接到同一个WiFi 网络(WiFi network)。
- 在您的 Android 设备上下载、安装和启动AirDroid应用程序。(AirDroid)
- 点击AirDroid Web并记下您在那里看到的本地IP 地址(IP address)。
- 在您的计算机(computer and type)上打开一个新的浏览器选项卡(browser tab)，然后输入您之前记下的IP 地址(IP address)。按Enter 键(Enter)，AirDroid将在您的计算机上启动。
- 在计算机上 AirDroid 的主界面上，找到并单击屏幕截图(Screenshot)选项。

屏幕截图将被捕获并保存在您的计算机上。
如果您愿意，您还可以通过单击剪刀图标(scissor icon)旁边的向下箭头图标，让AirDroid将屏幕截图保存在您的设备上。然后它会让你为你的截图文件选择一个目的地。
使用 Android Debug Bridge 捕获您的 Android 屏幕(Use Android Debug Bridge To Capture Your Android Screen)
ADB有许多命令可帮助您通过计算机在Android 设备(Android device)上执行操作。这个实用程序可以在有和没有电缆的情况下使用，但是设置有线的很容易，只需要半分钟。
在计算机上设置实用程序后，您需要做的就是发出命令，然后您的Android 屏幕截图(Android screenshot)就会被捕获。
- 在基于 Windows、Mac或Linux的计算机上下载并提取ADB 工具包。(ADB toolkit)
- 前往Settings > Developer options并在您的设备上启用USB 调试(USB debugging )。
- 将您的设备连接到计算机。Windows 用户应在ADB 文件夹中启动(ADB folder)命令提示符窗口(command prompt window)。Mac用户需要启动终端(Terminal)并将ADB文件夹设置为当前工作目录。
- 在您的计算机上运行以下命令以截取屏幕截图。
adb shell screencap -p /sdcard/screenshot.png (Windows 用户) ./adb shell screencap -p /sdcard/screenshot.png (Mac 用户)
- 执行以下命令将屏幕截图带到您的计算机。
adb pull /sdcard/screenshot.png (Windows 用户) ./adb pull /sdcard/screenshot.png (Mac 用户)
您将在ADB 文件夹(ADB folder)的根目录(root directory)中找到截图图像文件(image file)。
如果您在截屏时遇到任何困难，请确保您已在Android 设备上允许(Android device)USB调试提示。这使您的计算机可以访问(computer access)您的设备。
How To Take a Screenshot On Android
Screenshots are useful in many ways and you have lіkely captured them on your computers, especially if your work requires explaining things to people. With these screen captures, you can eаsily show people what your computer’s screen looks like and you can even add pоinters to draw people’s attentiоn to certain parts of the screenshot.
Like your desktop computer, your Android device also offers the option to capture screenshots. Android has this feature for a really long time and it’s available on most devices based on this operating system.
There are actually multiple ways to take screenshots on an Android device. Depending on what device you have and what your preferences are, you can use any of these methods to capture your screens.
Capture a Screenshot on Android Using a Key Combo
One of the convenient ways to capture your current screen on your device is to use a key combination. Almost every Android device that ships has a key shortcut that when pressed, takes a picture of your current screen.
This key combination isn’t fixed and it varies by device models. For example, the key combination that works on a OnePlus Android device may not work on a Samsung device even though both run the same operating system.
Here’s the list of the keys you need to press to take a screenshot on various Android devices:
- Google Pixel: Power + Volume Down
- Samsung: Power + Volume Down
- LG: Lock + Volume Down
- HTC: Power + Home
- OnePlus: Power + Volume Down
- Motorola: Power + Volume Down
- Sony: Power + Volume Down
As you can see, most devices use the Power and Volume Down key combo to capture a screenshot. If you can’t find a combination for your device in the list, use this generic one and it should work in most cases.
Take a Screenshot on Android Using The Power Button
On an Android device, the Power button does more than just turning your device on and off. It helps you lock your device, unlock your device, reboot your device, and even take a screenshot on your device.
While most users are aware of the common functions of the Power button, they may not know that the button has the screen capturing option available in it as well. This can be accessed by opening the power menu on your device.
This should work on most Android based phones and tablets
- Get to the screen where you want to take a screenshot.
- Press and hold down the Power button on your device.
- A menu will pop-up on your screen with a few options in it. Tap on the option that says Screenshot to capture a screenshot.
A screenshot of your current Android screen will be captured and saved in the default screenshots folder on your Android device. This screenshot will be without the power menu although you see the menu when the screenshot is being taken.
You can then find this screenshot using the file manager or gallery app on your device.
Grab a Screenshot On Your Android Device Wirelessly
If you’re going to transfer your screenshots from your device to your computer after capturing them, you don’t need to go through that hassle as you can take screenshots directly on your computer.
There’s a utility that allows you to take screenshots of your Android device on your computer wirelessly. It’s called AirDroid and you’ve likely heard of it if you’re a regular reader of this site (or if you’ve ever wanted to transfer files from Android to Mac or PC).
All that this requires is both your devices should be connected to the same WiFi network.
- Download, install, and launch the AirDroid app on your Android device.
- Tap on AirDroid Web and note down the local IP address you see there.
- Open a new browser tab on your computer and type in the IP address you noted down earlier. Hit Enter and AirDroid will launch on your computer.
- On the AirDroid’s main interface on your computer, find and click on the option that says Screenshot.
- You’ll instantly see your device’s screen being mirrored to your computer. Get to the screen where you want to capture a screenshot on your device and click on the scissor icon on your computer.
A screenshot will be captured and saved on your computer.
You can also get AirDroid to save screenshots on your device itself if you’d like by clicking on the down-arrow icon next to the scissor icon. It’ll then let you choose a destination for your screenshot files.
Use Android Debug Bridge To Capture Your Android Screen
ADB has a number of commands to help you execute actions on your Android device from your computer. This utility can be used both with and without cables but getting the wired one set up is pretty easy and only takes half a minute.
Once you’ve set the utility up on your computer, all you need to do is issue a command and your Android screenshot will be captured.
- Download and extract ADB toolkit on your Windows, Mac, or Linux based computer.
- Head to Settings > Developer options and enable USB debugging on your device.
- Connect your device to your computer. Windows users should launch a command prompt window in the ADB folder. Mac users need to launch Terminal and make the ADB folder your current working directory.
- Run the following command on your computer to take a screenshot.
adb shell screencap -p /sdcard/screenshot.png (Windows users)
./adb shell screencap -p /sdcard/screenshot.png (Mac users)
- Execute the following command to bring the screenshot to your computer.
adb pull /sdcard/screenshot.png (Windows users)
./adb pull /sdcard/screenshot.png (Mac users)
You’ll find the screenshot image file in the root directory of your ADB folder.
If you face any difficulties while capturing the screenshot, make sure you’ve allowed the USB debugging prompt on your Android device. This gives your computer access to your device.
