java按钮背景图片

为什么背景图片把文字挤到旁边去了呀？不是“背景”图片吗？在线等！！谢啦！菜鸟所以麻烦解释详细些。

附部分代码：
jbs=new JButton[24];
ImageIcon image = new ImageIcon("1.gif");
ImageIcon image2 = new ImageIcon("2.gif");
String[] strs={"1","2","3","4","5","6","7","8","9","0","+/-",".","/","sqrt","㏑","*","sin","←","-","cos","CE","+","y^2","="};
for(int i=0; i<12; i++){
jbs[i]=new JButton(strs[i],image);
jbs[i].setContentAreaFilled(false);
jbs[i].setMargin(new Insets(0,0,0,0));
jbs[i].setBorderPainted(false);
jbs[i].setBorder(BorderFactory.createRaisedBevelBorder());
jbs[i].setFont(new java.awt.Font("华文行楷", 3, 20));
}
for(int i=12; i<24; i++){
jbs[i]=new JButton(strs[i],image2);
jbs[i].setContentAreaFilled(false);
jbs[i].setMargin(new Insets(0,0,0,0));
jbs[i].setBorderPainted(false);
jbs[i].setBorder(BorderFactory.createRaisedBevelBorder());
jbs[i].setFont(new java.awt.Font("华文行楷", 3, 20));
}

Answer 1

其实是不需要放按钮的，你直接放图片就好了，而且还美观，图片有点击事件的！

Answer 2

这个不是背景图片，是按钮上的图标。

Answer 3

记不清楚了，加这试一下
jsb[i].setVerticalTextPosition(JButton.CENTER);
jsb[i].setHorizontalTextPosition(JButton.CENTER);
