How to call another activity(class) from one activity?

Question

I am using dialog box. I want that if i click the button, the other activity gets called. But its giving the following error. //The constructor Intent(new DialogInterface.OnClickListener(){}, Class) is undefined

Here's the code

  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)

                }
            });

start as:

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);
                }
            });

NOTE: Do not use getBaseContext() use getApplicationContext() or Current_Activity.thisenter code here for Starting new Activity

Could you explain why not to use getBaseContext(); – Carnal Jul 11 '12 at 07:18
see this post http://stackoverflow.com/questions/1026973/android-whats-the-difference-between-the-various-methods-to-get-a-context and this google official blog http://android-developers.blogspot.in/2009/01/avoiding-memory-leaks.html – ρяσѕρєя K Jul 11 '12 at 07:20
it' maybe cause memory leaks because it content old reference of Context if you are not updating it – ρяσѕρєя K Jul 11 '12 at 07:21

If you use the this, the class used in the Intent i=new Intent(this, FbsampleActivity.class) is DialogInterface.OnClickListener class. You need to write YourOuterClass.this (the outer class). Try this:

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

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

Intent i=new Intent(getApplicationContext(), FbsampleActivity.class)

In your case, "this" refers to the DialogInterface class. You need the context of your Activity.
