如何將日期文本（右下角）添加到圖像並保存

Question

我對Java很新。我需要將日期作爲右下角文本添加到我的相機拍攝的圖像中並保存。就像這樣：

Answer 1

試試這個代碼。

//得到今天的一天。並放入位於右下角的ListView中//在xml文件中。

final Calendar cal = Calendar.getInstance(); 
          year = cal.get(Calendar.YEAR); 
          month = cal.get(Calendar.MONTH)+1; 
          day = cal.get(Calendar.DAY_OF_MONTH); 

TextView out=(TextView)findViewById(R.id.yourtextview); 
out.setText(day+"."+month+"."+year); 

Answer 2

試試這個

import java.awt.Font; 
import java.awt.Graphics; 
import java.awt.image.BufferedImage; 
import java.io.File; 
import java.io.IOException; 
import java.text.SimpleDateFormat; 
import java.util.Date; 

import javax.imageio.ImageIO; 
import javax.swing.ImageIcon; 

public class WatermarkImage { 

     public static void main(String[] args) { 

      SimpleDateFormat sdfDate = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); 
      Date now = new Date(); 

      File origFile = new File("E:/watermark/test.jpg"); 
      ImageIcon icon = new ImageIcon(origFile.getPath()); 

      // create BufferedImage object of same width and height as of original image 
      BufferedImage bufferedImage = new BufferedImage(icon.getIconWidth(), 
         icon.getIconHeight(), BufferedImage.TYPE_INT_RGB); 

      // create graphics object and add original image to it 
      Graphics graphics = bufferedImage.getGraphics(); 
      graphics.drawImage(icon.getImage(), 0, 0, null); 

      // set font for the watermark text 
      graphics.setFont(new Font("Arial", Font.BOLD, 20)); 
      String watermark = sdfDate.format(now); 

      // add the watermark text 
      graphics.drawString(watermark, (icon.getIconWidth()*80)/100, (icon.getIconHeight()*90)/100); 
      graphics.dispose(); 

      File newFile = new File("E:/watermark/WatermarkedImage.jpg"); 
      try { 
        ImageIO.write(bufferedImage, "jpg", newFile); 
      } catch (IOException e) { 
        e.printStackTrace(); 
      } 

      System.out.println(newFile.getPath() + " created successfully!"); 

     } 

}
