pc端获取android的截屏

原理：

通过在PC端获取android端的截图。主要是通过利用ddmlib中提供的方法进行获取。

需要应用sdk工具包ddmlib.jar.

import com.android.ddmlib.AdbCommandRejectedException;

import com.android.ddmlib.AndroidDebugBridge;

import com.android.ddmlib.IDevice;

import com.android.ddmlib.RawImage;

import com.android.ddmlib.TimeoutException;

import java.awt.image.BufferedImage;

import java.awt.image.RenderedImage;

import java.io.File;

import java.io.IOException;

import javax.imageio.ImageIO;

public class Jietu {



public static void main(String[] args)

{

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

AndroidDebugBridge bridge = AndroidDebugBridge.createBridge(

"E:\\work\\soft\\android-sdk-windows\\android-sdk-windows\\tools\\adb.exe", true /* forceNewBridge */);

IDevice device;

waitDeviceList(bridge);

IDevice devices[] = bridge.getDevices();

device = devices[0];

try {

RawImage rawScreen = device.getScreenshot();



saveImage(rawScreen);



} catch (TimeoutException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (AdbCommandRejectedException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

private static void waitDeviceList(AndroidDebugBridge bridge) {

int count = 0;

while (bridge.hasInitialDeviceList() == false) {

try {

Thread.sleep(100); // 如果没有获得设备列表，则等待

count++;

} catch (InterruptedException e) {}

if (count > 300) { // 设定时间超过300×100 ms的时候为连接超时

System.err.print("Time out");

break;

}

}

}

private static void saveImage(RawImage rawScreen)

{

if(rawScreen != null){

BufferedImage image = null;

boolean landscape=false;

//横屏竖屏

// int width2 = landscape ? rawScreen.height : rawScreen.width;

// int height2 = landscape ? rawScreen.width : rawScreen.height;

int width2 = rawScreen.width;

int height2 = rawScreen.height;

if (image == null) {

image = new BufferedImage(width2, height2,

BufferedImage.TYPE_INT_RGB);

} else {

if (image.getHeight() != height2 || image.getWidth() != width2) {

image = new BufferedImage(width2, height2,

BufferedImage.TYPE_INT_RGB);

}

}

int index = 0;

int indexInc = rawScreen.bpp >> 3;

for (int y = 0; y < rawScreen.height; y++) {

for (int x = 0; x < rawScreen.width; x++, index += indexInc) {

int value = rawScreen.getARGB(index);

if (landscape)

image.setRGB(y, rawScreen.width - x - 1, value);

else

image.setRGB(x, y, value);

}

}

try {

ImageIO.write((RenderedImage)image,"PNG",new File("D:/temp.jpg"));

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

}

}
