Answer 2

12-26 11:43:06.253: E/AndroidRuntime(506): java.lang.NoClassDefFoundError: com.project.findmybuffet.SearchPage
12-26 11:43:06.253: E/AndroidRuntime(506):  at com.project.findmybuffet.AndroidTabRestaurantDescListView$3.onClick(AndroidTabRestaurantDescListView.java:101)

It is unable to find com.project.findmybuffet.SearchPage class. Please check your package name once.

<activity android:name="com.project.findmybuffet.SearchPage" >
        </activity>

You have mentioned your search page activity in this path "com.project.findmybuffet.SearchPage" so please check whether that SearchPage.class is in that path or not. If everything is good. Try clean your project and run again

Now try this

Photos.setOnClickListener(new OnClickListener() {

            public void onClick(View v) {
                // TODO Auto-generated method stub

                Intent photoIntent=new Intent(AndroidTabRestaurantDescListView.this,AndroidTabRestaurantDescImageListView.class);
                startActivity(photoIntent);

            }
        });


        Filter.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                Intent filterIntent=new Intent(AndroidTabRestaurantDescListView.this,Filters.class);
                startActivity(filterIntent);
            }
        });


        Search.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                Intent searchIntent=new Intent(AndroidTabRestaurantDescListView.this,SearchPage.class);
                startActivity(searchIntent);
            }
        });


        Account.setOnClickListener(new OnClickListener() {

            public void onClick(View v) {
                // TODO Auto-generated method stub

                Intent accountIntent=new Intent(AndroidTabRestaurantDescListView.this,RestaurantAccount.class);
                startActivity(accountIntent);

            }
        });
