Java Swing实现android手机截图

对于不同测试机型截图的快捷键有很大差别，由于本人比较懒，不想记各种机型的截屏快捷键，对此我直接写了android手机截图，实现方式用的是java swing界面，界面如下

整体思路如下，点击截图路径按钮弹出路径选择框，点击确定后，JTextfiled显示路径，点击截图按钮，执行截图命令，截图的路径为JTextfiled显示的路径，截图命令成功后弹出截图成功的Toast

下面附上所有代码：

1.获取当前时间工具类

import java.text.SimpleDateFormat;
import java.util.Date;
public class GetStringTimeUtils {
    //获取String类型的时间格式
    public static String getTime(){
        SimpleDateFormat df = new SimpleDateFormat("yyyyMMddHHmmss");
        String date = df.format(new Date());
        return date;
    }
    
}

2.cmd命令执行工具类

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.ArrayList;
import java.util.List;

public class CmdUtils {
    List<String>resultList=new ArrayList<String>();
    public List<String> excuteCmd(String command){
        //String command="adb devices";
        String line = null;
        StringBuilder sb = new StringBuilder();
        Runtime runtime = Runtime.getRuntime();
        try {
            Process process = runtime.exec(command);
            BufferedReader  bufferedReader = new BufferedReader(new InputStreamReader(process.getInputStream()));
            while ((line = bufferedReader.readLine()) != null) {
                resultList.add(line);
            
            }
        } catch (IOException e) {
            
            e.printStackTrace();
        }
        return resultList;
        
    }


}

3.Toast类

import java.awt.Color;  
import java.awt.Composite;  
import java.awt.Dimension;  
import java.awt.Font;  
import java.awt.FontMetrics;  
import java.awt.Graphics;  
import java.awt.Graphics2D;  
import java.awt.Insets;  
import java.awt.RenderingHints;  
import java.awt.Window;  
import java.awt.font.FontRenderContext;  
import java.awt.geom.Rectangle2D;  
import java.util.Timer;  
import java.util.TimerTask;  
import javax.swing.JWindow; 

//自定义toast
public class Toast extends JWindow{
    private static final long serialVersionUID = 1L;  
    private String message = "";  
    private final Insets insets = new Insets(12, 24, 12, 24);  
    private int period = 1500;  
    private Font font;  
    public static final int msg = 0;// 提示 黑色背景色  
    public static final int success = 1;// 成功提示 浅蓝色背景色  
    public static final int error = 2;// 错误提示 粉红色背景色  
    private Color background;  
    private Color foreground;
    
    public Toast(Window parent, String message, int period) {  
        this(parent, message, period, 0);  
  
    }  
    
    public Toast(Window parent, String message, int period, int type) {  
        super(parent);  
        this.message = message;  
        this.period = period;  
        font = new Font("宋体", Font.PLAIN, 14);  
        setSize(getStringSize(font, true, message));  
        // 相对JFrame的位置  
        setLocationRelativeTo(parent);  
        installTheme(type);  
  
    }  
    
    @Override  
    public void paint(Graphics g) {  
        Graphics2D g2 = (Graphics2D) g;  
        // old  
        Composite oldComposite = g2.getComposite();  
  
        g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING,  
                RenderingHints.VALUE_ANTIALIAS_ON);  
        g2.setFont(font);  
        FontMetrics fm = g2.getFontMetrics();  
        g2.setColor(background);  
        g2.fillRoundRect(0, 0, getWidth(), getHeight(), 12, 12);  
        g2.setColor(foreground);  
        g2.drawString(message, insets.left, fm.getAscent() + insets.top);  
        // restore  
        g2.setComposite(oldComposite);  
    }  
  
    /** 
     * 启动提示 
     */  
  
    public void start() {  
        this.setVisible(true);  
        Timer timer = new Timer();  
        timer.schedule(new TimerTask() {  
            @Override  
            public void run() {  
                setVisible(false);  
            }  
        }, period);  
    }  
    
    public void setMessage(String message) {  
        this.message = message;  
        Dimension size = getStringSize(font, true, message);  
        setSize(size);  
        revalidate();  
        repaint(0, 0, size.width, size.height);  
        if (!isVisible()) {  
            start();  
        }  
    }  
    
    private void installTheme(int type) {  
        switch (type) {  
        case msg:  
            background = new Color(0x515151);  
            foreground = Color.WHITE;  
            break;  
        case success:  
            background = new Color(223, 240, 216);  
            foreground = new Color(49, 112, 143);  
            break;  
        case error:  
            background = new Color(242, 222, 222);  
            foreground = new Color(221, 17, 68);  
            break;  
  
        default:  
            background = new Color(0x515151);  
            foreground = Color.WHITE;  
            break;  
        }  
    }  
    
    private Dimension getStringSize(Font font, boolean isAntiAliased,  
            String text) {  
        FontRenderContext renderContext = new FontRenderContext(null,  
                isAntiAliased, false);  
        Rectangle2D bounds = font.getStringBounds(text, renderContext);  
        int width = (int) bounds.getWidth() + 2 * insets.left;  
        int height = (int) bounds.getHeight() + insets.top * 2;  
        return new Dimension(width, height);  
    }  
}

4.截图功能类

import javax.swing.JComboBox;
import javax.swing.JOptionPane;
import javax.swing.JTextField;

//截图线程

public class ScreenCapTask extends Thread {
    CmdUtils cmdUtils=new CmdUtils();
    JTextField textField;
    
    
    String device;
    public ScreenCapTask(JTextField textField){
        this.textField=textField;
        
    }
    @Override
    public void run() {
        // TODO Auto-generated method stub
        super.run();
        
        //截图命令
        String command="adb shell screencap -p /sdcard/screen.png";
        cmdUtils.excuteCmd(command);
        
        if(textField.getText().toString().equals("")){
            //未选择路径弹出未选择路径的提示框
            JOptionPane.showConfirmDialog(null, "未选择截图路径,日志文件保存在手机/sdcard/screen.png中","输入提示", JOptionPane.DEFAULT_OPTION);
        }
        else{
            //截图后从手机将截图推到选择的路径下
            String command1="adb pull /sdcard/screen.png "+textField.getText();

            System.out.println(command);
            
            cmdUtils.excuteCmd(command1);
            
        }
        
    }
}
