Как начать новую деятельность с использованием startActivity (намерение) в пользовательском адаптере RecyclerView?

Question

У меня есть файл CustomRecyclerViewAdapter.class, в котором я реализовал метод ниже.

public void onBindViewHolder(RecyclerViewHolder viewHolder, int position) 
{ 
    viewHolder.title.setText(mData.get(position).text); 
    //viewHolder.icon.setBackgroundColor(Color.parseColor(mData.get(position).color)); 

    viewHolder.setClickListener(new RecyclerViewHolder.ClickListener(){ 

     @Override 
     public void onClick(View v, int position, boolean isLongClick) { 

      if (isLongClick) { 
       // View v at position pos is long-clicked. 
       Toast.makeText(v.getContext(), "Hey you just hit item" + position, Toast.LENGTH_SHORT).show(); 


      }else { 
       // View v at position pos is clicked. 
       //how to start a new activity here 
       Toast.makeText(v.getContext(),"Hey you just hit item" + position,Toast.LENGTH_SHORT).show(); 
      } 


     } 
    }); 

} 

Так как я могу начать новую деятельность в блоке else выше.

Group.class

public class Group extends ActionBarActivity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState);//line no. 16 which is indicated in logcat 
     setContentView(R.layout.group); 

     getSupportActionBar().setHomeButtonEnabled(true); 
     getSupportActionBar().setDisplayHomeAsUpEnabled(true); 

} 

Это моя ошибка LogCat .....

Спасибо за ваше время.

Вы можете использовать любой вид. Метод getContext() предоставляет почти методы активности, поскольку Activity расширяет контекст.

v.getContext().startActivity(intent);
