卡片布局java

『壹』 java 卡片布局問題

先添加一個面板，把布局設置成CardLayout然後再向這個面板中添加新的面板。。就可以了。。。然後面板的轉換用按鈕做，給按鈕添加單擊事件。

這是用面板布局做的一個簡單示例，你可以看一下，在JBUilder裡面寫的，可能不能運行。但你可以借鑒一下。

『貳』 在Java中用了卡片布局，怎麼設置組建的位置

你好，我剛剛也找了很久，我沒找到答案，後來我自己反復調試，現在知道了，
你需要
c1 = new CardLayout();
jp1 = new JPanel(c1);//最大的容器
//（這里假設你的卡片布局用的是c1,您修改為您自己的就行）
c1.setHgap(50);//調整距離左邊的距離
c1.setVgap(50);//調整距離頂部的距離
如有疑問，請評論留言，希望有所幫助。

『叄』 java卡片布局show的使用。下面代碼中LayoutDemo中「日記本」按鈕顯示TestFlowLayoutone 代碼

卡片布局裡面，好像只有一個布局。

另外對象的比較，不可以簡單地使用=，要使用對象.equals(object)

代碼是精簡過的，最大的區別在圖片中代碼的30幾行、60幾行，，，，，把內部類，放回到外面，一樣使用的。

『肆』 JAVA 卡片布局

問題一:

這段代碼中，包含了一個成員變數i和類Cvs的構造方法，請問一下，括弧里的int j是什麼？還有，i與j在之前都沒有聲明或者賦值過，那麼這里的i和j的值又是什麼？為什麼？

答案一:

你的i,j都沒有賦值,但是在用Cvs構造方法時候初始化了
你看
"for(int k=0;k<=9;k++)
{
cvs[k]=new Cvs(k); //在這呢,調用你的 Cvs(int j)構造
pnl.add(""+k,cvs[k]);
}"

這個時候 i,j,k就是一個值了i=j=k了

問題二:

for(int k=0;k<=9;k++)
{
cvs[k]=new Cvs(k);
pnl.add(""+k,cvs[k]);
}
這句話是不是在面板中添加了10個不同的畫布？

答案二:

是的,對的

問題三:

後面的pnl.add(""+k,cvs[k]);為什麼k前面要加一個空字元？

答案三:

你看看 k是個整數對吧,但是add()方法是不能用整數對象的,要轉換成字元串對象,""+k就是相當與把k與一個空的字元串相加,這時候k就變成字元串了,懂吧,書上都有

問題四:

在開頭建立Cvs的類對象時用了數組，是建立類對象么？為什麼要用數組？

答案四:

是滴,用數組可以建立多個對象啊,而且方便.

問題五:

這句話的意義？

答案五:

這句話的意思就是建立10個不同的畫布對象.

『伍』 java卡片布局中show的正確使用方法

已修改，復制粘貼即可，
panelMain=newPanel(cl);//被設定為卡片布局的面板
修改如上即可


importjava.awt.BorderLayout;
importjava.awt.Button;
importjava.awt.CardLayout;
importjava.awt.FlowLayout;
importjava.awt.Frame;
importjava.awt.Label;
importjava.awt.Panel;
importjava.awt.event.ActionEvent;
importjava.awt.event.ActionListener;
importjava.awt.event.WindowAdapter;
importjava.awt.event.WindowEvent;

publicclassCeshiextendsFrame
{
	PanelFpf=newPanelF();
	PanelSps=newPanelS();
	PanelpanelMain,panelXZ;
	ButtonbtNext,btPrevious,bt1,bt2,bt3,bt4,bt5;
	CardLayoutcl;
	Booleanw=false;

	publicCeshi()
	{
		cl=newCardLayout();
		panelMain=newPanel(cl);//被設定為卡片布局的面板
		panelXZ=newPanel();//構造放按鈕的面板
		btPrevious=newButton("上一頁");
		btNext=newButton("下一頁");
		bt1=newButton("1");
		bt2=newButton("2");
		//給定義為卡片布局的面板添加面板
		panelMain.add(pf,"pf");
		panelMain.add(ps,"ps");
		panelXZ.add(btPrevious);
		panelXZ.add(btNext);
		panelXZ.add(bt1);
		panelXZ.add(bt2);
		btPrevious.addActionListener(newActionListener()
		{
			@Override
			publicvoidactionPerformed(ActionEvente)
			{
				cl.previous(panelMain);
			}
		});
		btNext.addActionListener(newActionListener()
		{//下一頁的按鈕
				publicvoidactionPerformed(ActionEvente)
				{
					cl.next(panelMain);
				}
			});
		bt1.addActionListener(newActionListener()
		{//跳轉到第二個面板的按鈕
			publicvoidactionPerformed(ActionEvente)
			{
				cl.show(panelMain,"pf");
			}
		});
		bt2.addActionListener(newActionListener()
		{//跳轉到第二個面板的按鈕
			publicvoidactionPerformed(ActionEvente)
			{
				cl.show(panelMain,"ps");

		addWindowListener(newWindowAdapter()
		{
			publicvoidwindowClosing(WindowEventwevent)

					dispose();
				else
					System.exit(0);
			}
		});
		panelXZ.setLayout(newFlowLayout());
		setTitle("主界面");
		setSize(800,600);
		setLocationRelativeTo(null);
		add(panelMain,BorderLayout.CENTER);//把設為卡片布局的面板放置在窗體中間
		add(panelXZ,BorderLayout.SOUTH);//把帶按鈕的面板放置在底部
		setVisible(true);
	}

	publicstaticvoidmain(Stringargs[])
	{
		newCeshi();
	}
}

//第一個面板
classPanelFextendsPanel
{
	publicPanelF()
	{
		add(newLabel("第一個面板"));
	}
}

//第二個面板
classPanelSextendsPanel
{
	publicPanelS()
	{
		add(newLabel("第二個面板"));
	}
}

『陸』 JAVA卡片布局，代碼求糾錯。

public void actionPerformed(ActionEvent event) {
if(event.getSource()==Button1){
// car.next(cards);
car.first(cards);
}else{
car.last(cards);
// car.previous(cards);
}

}

『柒』 java的卡片布局

JFrame
j=new
JFrame();
j.getContentPane().add("West",「您組件所在的面板")//這里不用setLayout，默認已經是BorderLayout
或者是用j.getContentPane().setLayout(null);再setBounds(坐標，坐標，長，寬);比較靈活，但是比較麻煩
