I have to connect three activities "rectangle, circle, triangle", which once selected on main screen, brings me to my other activity screens. but when I click on " example" rectangle, it brings me back to my start button " click here to pick a shape"

Code:

Override
protected Dialog onCreateDialog(int id) {
    switch (id) {
    case 0:
        return new AlertDialog.Builder(this)
        .setIcon(R.drawable.ic_launcher)
        .setTitle("Please pick a Shape")
            .setItems(items, 
                            new DialogInterface.OnClickListener() {
                                public void onClick(DialogInterface dialog,
                                int which) {  
                                switch (which) {
                                
                                case 1:
                                	startActivity(new Intent(getApplicationContext(), Rectangle_Activity.class));
                                    break;
                                case 2:
                                	startActivity(new Intent(getApplicationContext(), Circle_Activity.class));
                                    break;
                                case 3: 
                                	startActivity(new Intent(getApplicationContext(), Triangle_Activity.class));
                                	break; 
                                	
                                default: break;

                                }
