在PC端进行android截屏的多种方法

阅读更多

昨晚意外的发现在PC端进行截屏的方法相当多，在android sdk的tools里面有大量的jar包可以利用。
第一种方法：
这里使用AndroidDebugBridge及其相关类进行截屏，使用的jar包是ddmlib.jar，在android sdk的tools文件夹内。
代码如下（以下代码抽取自互联网并经修改过）：

public class AdbUtil {
	public static IDevice connect() {
		// init the lib
		// [try to] ensure ADB is running
		String adbLocation = System.getProperty("com.android.screenshot.bindir"); //$NON-NLS-1$
		if (adbLocation != null && adbLocation.length() != 0) {
			adbLocation += File.separator + "adb"; //$NON-NLS-1$
		} else {
			adbLocation = "adb"; //$NON-NLS-1$
		}

		AndroidDebugBridge.init(false /* debugger support */);

		AndroidDebugBridge bridge = AndroidDebugBridge
				.createBridge(adbLocation, true /* forceNewBridge */);

		// we can't just ask for the device list right away, as the internal
		// thread getting
		// them from ADB may not be done getting the first list.
		// Since we don't really want getDevices() to be blocking, we wait
		// here manually.
		int count = 0;
		while (bridge.hasInitialDeviceList() == false) {
			try {
				Thread.sleep(100);
				count++;
			} catch (InterruptedException e) {
				// pass
			}

			// let's not wait > 10 sec.
			if (count > 100) {
				System.err.println("Timeout getting device list!");
				return null;
			}
		}

		// now get the devices
		IDevice[] devices = bridge.getDevices();

		if (devices.length == 0) {
			System.out.println("No devices found!");
			return null;
		}

		return devices[0];
	}

	public static BufferedImage screenShot(IDevice device) {
		RawImage rawImage;
		try {
			rawImage = device.getScreenshot();
		} catch (Exception ioe) {
			System.out.println("Unable to get frame buffer: " + ioe.getMessage());
			return null;
		}

		// device/adb not available?
		if (rawImage == null)
			return null;

		// convert raw data to an Image
		BufferedImage image = new BufferedImage(rawImage.width, rawImage.height,
				BufferedImage.TYPE_INT_ARGB);

		int index = 0;
		int IndexInc = rawImage.bpp >> 3;
		for (int y = 0; y < rawImage.height; y++) {
			for (int x = 0; x < rawImage.width; x++) {
				int value = rawImage.getARGB(index);
				index += IndexInc;
				image.setRGB(x, y, value);
			}
		}
		return image;
	}

	/**
	 * Grab an image from an ADB-connected device.
	 */
	public static boolean screenShotAndSave(IDevice device, String filepath) throws IOException {
		boolean result = ImageIO.write(screenShot(device), "png", new File(filepath));
		if (result) {
			System.out.println("file is saved in:" + filepath);
		}
		return result;
	}

	public static void terminate() {
		AndroidDebugBridge.terminate();
	}
}

第二种方法：
使用monkeyrunner.jar包，当然还要添加相关jar包。由于新版的API改变，不知道其中参数应该怎么传，未深入去做。

第三种方法，使用chimpchat.jar及相关jar包（common.jar,guava-13.0.1.jar），代码大致如下：

		AdbBackend adb = new AdbBackend();
		IChimpDevice device = adb.waitForConnection();
		ImageIO.write(device.takeSnapshot().createBufferedImage(), "png", new File("E:\\tmp.png"));
		device.dispose();
		if (adb != null) {
			adb.shutdown();
		}

但是执行之后，程序没有停止下来，不知如何才能使其终止。
