我創建了一個RecyclerView，帶有itemobjects，Adapter，viewholder和activity。getActivity（）在視圖內
Recyclerview正常工作。
我的問題是當從Recyclerview中點擊一個項目時，我想引導用戶到TicketDetails活動。
我有代碼來獲取點擊的項目和它的視圖擋位置，但是當我嘗試創建一個新的意圖，新的活動像這裏面的觀點持有者
startActivity(new Intent(getActivity(), TicketDetails.class));
我無法解決getActivity（）
ViewHolder

import android.support.v7.widget.RecyclerView;

import com.example.baman.zupportdesk.R;
import com.example.baman.zupportdesk.TicketDetails;
import static android.support.v4.app.ActivityCompat.startActivity;
public class TicketsRecyclerViewHolders extends RecyclerView.ViewHolder implements View.OnClickListener{
public ImageView priority;
public TextView sts_open;
public TextView sts_overdue;
public TextView tkt_from;
public TextView tkt_subject;
public TextView tkt_assignedto;
public TextView tkt_created_date;
public TextView txt_ticket_id;
private SparseBooleanArray selectedItems = new SparseBooleanArray();
public TicketsRecyclerViewHolders(View itemView) {
super(itemView);
itemView.setOnClickListener(this);
priority = (ImageView) itemView.findViewById(R.id.priority_status_icon);
sts_open= (TextView) itemView.findViewById(R.id.tv_Tk_opn_status);
sts_overdue = (TextView) itemView.findViewById(R.id.tv_Tk_overdue);
tkt_from = (TextView) itemView.findViewById(R.id.tv_Tk_from);
tkt_subject = (TextView) itemView.findViewById(R.id.tv_Tk_subject);
tkt_assignedto = (TextView) itemView.findViewById(R.id.tv_Tk_Assignedto);
tkt_created_date = (TextView) itemView.findViewById(R.id.tv_Tk_Created_date);
txt_ticket_id = (TextView) itemView.findViewById(R.id.tv_Tk_TicketID);
}
@Override
public void onClick(View view) {
int position = getAdapterPosition();
String ticket_id = txt_ticket_id.getText().toString();
Log.d("ZD-clicked : ", "Position => "+String.valueOf(position)+", Ticket Id => "+ticket_id);
startActivity(new Intent(getActivity(), TicketDetails.class));
// if (selectedItems.get(getAdapterPosition(), false)) {
// selectedItems.delete(getAdapterPosition());
// view.setSelected(false);
// }
// else {

Hy Tnx。但是現在我無法解決'startActivity'。我清理了項目並反駁了項目'錯誤：（62，9）錯誤：找不到符號方法startActivity（意圖）' –
更新了答案，使用上下文來啓動Activity。 –
Thx Bro。有用。 –
