如何从一个活动中调用另一个活动(类)？

Question

我正在使用对话框.我希望如果我单击按钮,则会调用其他活动.但它给出了以下错误.//构造函数Intent(new DialogInterface.OnClickListener(){},Class)未定义

这是代码

  builder1.setNegativeButton("secondact", new DialogInterface.OnClickListener() {

                public void onClick(DialogInterface dialog, int which) {
                    // TODO Auto-generated method stub
                    Intent i=new Intent(this, FbsampleActivity.class)

                }
            });

开始时间:

builder1.setNegativeButton("secondact", new DialogInterface.OnClickListener() {

                public void onClick(DialogInterface dialog, int which) {
                    // TODO Auto-generated method stub
                    Intent i=new Intent(Current_Activity.this, FbsampleActivity.class);
                    //or

                    //Intent i=new Intent(getApplicationContext(), FbsampleActivity.class);
                     startactivity(i);
                }
            });

注意: 请勿使用getBaseContext()use getApplicationContext()或Current_Activity.this enter code here来启动新活动
