将图像添加到Jbutton与前景标签

Question

朋友，我尝试使用seticon方法将图像添加到我的Jbutton，但它隐藏按钮上的文本标签。代码如下：

 try { 
     Image img = ImageIO.read(getClass().getResource("image.jpg")); 
     studentsButton.setIcon(new ImageIcon(img));   
     } catch (IOException ex) { 
     } 

我在Eclipse中使用swing没有init（）/ paint

Answer 1

只需使用

studentsButton.setHorizontalTextPosition(AbstractButton.CENTER); 
studentsButton.setVerticalTextPosition(AbstractButton.BOTTOM); 

这会简单地将图片下面的文字。和输出将是这样的：

这里是有作为输出你的帮助，一个代码示例：

import java.awt.*; 
import java.io.IOException; 
import java.net.MalformedURLException; 
import java.net.URL; 
import javax.swing.*; 
import javax.imageio.ImageIO; 

public class ButtonImageExample 
{ 
    private JButton imageButton; 
    private ImageIcon image; 

    private void displayGUI() 
    { 
     JFrame frame = new JFrame("Button Image Example"); 
     frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 

     JPanel contentPane = new JPanel(); 
     try 
     { 
      image = new ImageIcon(ImageIO.read(
        new URL("http://i.imgur.com/6mbHZRU.png"))); 
     } 
     catch(MalformedURLException mue) 
     { 
      mue.printStackTrace(); 
     } 
     catch(IOException ioe) 
     { 
      ioe.printStackTrace(); 
     }  

     imageButton = new JButton("Button Text"); 
     imageButton.setIcon(image); 
     imageButton.setHorizontalTextPosition(AbstractButton.CENTER); 
     imageButton.setVerticalTextPosition(AbstractButton.BOTTOM); 

     contentPane.add(imageButton); 

     frame.setContentPane(contentPane); 
     frame.pack(); 
     frame.setLocationByPlatform(true); 
     frame.setVisible(true); 
    } 

    public static void main(String... args) 
    { 
     SwingUtilities.invokeLater(new Runnable() 
     { 
      public void run() 
      { 
       new ButtonImageExample().displayGUI(); 
      } 
     }); 
    } 
}

    } 
} 

这里是相同的输出：
