Сообщение об ошибке

Error:(75, 38) error: incompatible types: OneFragment cannot be converted to Context 
Error:(72, 45) error: incompatible types: OneFragment cannot be converted to Activity 
Error:(223, 32) error: cannot find symbol variable view 
Error:(106, 52) error: not an enclosing class: IconTextTabsActivity 

Я хочу, чтобы объединить представление списка и вкладка активности с JSON .Однако он получает ошибки в следующих 4 строках, и я не знаю, как его решить.

listadapter = new CustomListAdapter(this, patientList); 

    pDialog = new ProgressDialog(this); 

    Toast.makeText(IconTextTabsActivity.this, "row " + position + " was pressed", Toast.LENGTH_LONG).show(); 

    public PatientList() { 
//Required empty public constructor 

} 

Прошу вас, пожалуйста, помочь вам справиться с этим. Спасибо.

Answer 1

// Откройте свою основную деятельность и увеличьте класс из TabActivity.

public class AndroidTabAndListView extends TabActivity 

// Теперь откройте файл main.xml под res -> layout и создайте вкладку.

// Создание активностей для вкладок и расширять классы от ListActivity

public class Activity extends ListActivity 

// создать макеты XML для представлений списка.

// Каждой вкладке может понадобиться значок, чтобы значки дизайна для каждой вкладки.
