1,java端

 

private static Handler mHandler = null;

private static AppActivity instance = null;

@Override
protected void onCreate(final Bundle savedInstanceState) {
	super.onCreate(savedInstanceState);
	
	instance = AppActivity.this;
}

public static Object getInstance(){
	return instance;
}

public void exitGameJava(){
	mHandler = new Handler(Looper.getMainLooper());
	mHandler.postDelayed(new Runnable()
	{
		@Override
		public void run() {
			Log.e("exitGameJava", "exitGameJava");

			// TODO Auto-generated method stub
			Builder builder = new Builder(AppActivity.this);
			builder.setTitle("提示");
			builder.setMessage("确认退出游戏");
			builder.setPositiveButton("确定", new OnClickListener(){
				@Override
				public void onClick(DialogInterface dialog, int which) {
					// TODO Auto-generated method stub
					System.exit(0);
				}
			}).setNegativeButton("取消", new OnClickListener(){

				@Override
				public void onClick(DialogInterface dialog, int which) {
					// TODO Auto-generated method stub

					dialog.dismiss();
				}
				
			}).show();
		}
		
	}, 1);	
}


 

2，c++端

#if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID)
    #include "platform/android/jni/JniHelper.h"
    #define CLASS_NAME "org/cocos2dx/cpp/AppActivity"
#endif

#if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID)
    JniMethodInfo minfo;
    jobject jobj;
    if(JniHelper::getStaticMethodInfo(minfo, CLASS_NAME, "getInstance", "()Ljava/lang/Object;"))
    {
        jobj = minfo.env->CallStaticObjectMethod(minfo.classID, minfo.methodID);
        if(JniHelper::getMethodInfo(minfo, CLASS_NAME, "exitGameJava", "()V"))
        {
            if(jobj == NULL)
            {
                return;
            }
            minfo.env->CallVoidMethod(jobj, minfo.methodID);
            CCLOG("<<<jni调用退出游戏对话框成功");
        }
    }
#endif

 

 

 



 

 

 

 

一、只弹出提示信息

JOptionPane.showMessageDialog(null, "问题不能为空","格式错误",JOptionPane.ERROR_MESSAGE);



二、可以选择确认或取消

程序：

import java.awt.BorderLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JOptionPane;
import javax.swing.JPanel;
import javax.swing.JTextArea;

public class TestJoptionPane {
	public static void main(String[] args)
	{
		TestJoptionPane main1 = new TestJoptionPane();
		main1.go();
	} 
	
	void go()
	{
		JFrame frame = new JFrame("你好世界");
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		JButton button = new JButton("点我测试");
		button.addActionListener(new buttonListener());
		
		JTextArea textArea = new JTextArea(10,20);
		JPanel mainpanel = new JPanel();
		mainpanel.add(button);
		frame.getContentPane().add(BorderLayout.CENTER,mainpanel);
		frame.setSize(450,550);
		frame.setVisible(true);
	}
	
	class buttonListener implements ActionListener{

	@Override
	public void actionPerformed(ActionEvent e) {
		// TODO 自动生成的方法存根
		int res =  JOptionPane.showConfirmDialog(null,"是否继续","我要提示你",
				JOptionPane.YES_NO_OPTION);
		if (res == JOptionPane.YES_OPTION)
		{
			System.out.println("点击了YES");
		}
		else 
		{
			System.out.println("点击了NO");
		}
	}
	
	}
}





对话框：





输出结果：

点击了YES


 

1、简单的
JOptionPane.showMessageDialog(null, "消息提示");



2、内容多一点的，有个错误图片的
JOptionPane.showMessageDialog(null, "lala！", "错误点击",JOptionPane.WARNING_MESSAGE);

显示一个错误对话框，该对话框显示的 message 为 '年龄请输入数字',标题为“标题【出错啦】”:

JOptionPane.showMessageDialog(null, "标题【错误】", "格式输入错误", JOptionPane.ERROR_MESSAGE);

显示一个信息面板，其 options 为 "yes/no"，message 为 '输入为空是否继续'： 

package examples;

import javax.swing.JOptionPane;

public class TestClass {
	public static void main(String[] args) {
		int res = JOptionPane.showConfirmDialog(null, "是否继续操作", "是否继续", JOptionPane.YES_NO_OPTION);
		if (res == JOptionPane.YES_OPTION) {
			System.out.println("选择是后执行的代码"); // 点击“是”后执行这个代码块
		} else {
			System.out.println("选择否后执行的代码"); // 点击“否”后执行这个代码块
			return;
		}
	}
}
