Я хочу использовать Intent And Want, чтобы перейти к другому классу viewpager, и я использую Intent для этого, как
private void gotInvoiceClass(String fname) {
Intent goToUpdate = new Intent (mContext,Invoices.class);
goToUpdate.putExtrka("FIRSTNAME", fname);
mContext.startActivity(goToUpdate);
}
Я знаю, что вышеописанный метод используется для перехода от класса к деятельности;почему этот метод невозможен в случае использования намерения из класса viewpager в другой класс viewpager.Вот мой полный класс адаптера пейджера представления
public class ClientRecyclerAdapter extends RecyclerView.Adapter<ClientRecyclerAdapter.ClientViewHolder> {
private List<GetSetClientsDetail> listOrders;
Context mContext;
RecyclerView mRecyclerView;
View itemView;
public ClientRecyclerAdapter(List<GetSetClientsDetail> listOrders, RecyclerView recyclerView) {
this.listOrders = listOrders;
mRecyclerView = recyclerView;
}
@Override
public ClientViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
mContext = parent.getContext();
itemView = LayoutInflater.from(parent.getContext())
.inflate(R.layout.items_clients_table, parent, false);
return new ClientViewHolder(itemView);
}
public class ClientViewHolder extends RecyclerView.ViewHolder {
public TextView lblName;
public TextView lblRoute;
public TextView lblType;
public TextView lblCName;
public TextView lblContact;
RelativeLayout clientitemslayout;
public ClientViewHolder(View view) {
super(view);
lblName = view.findViewById(R.id.lblBName);
lblRoute = view.findViewById(R.id.lblRoute);
lblType = view.findViewById(R.id.lblType);
lblCName = view.findViewById(R.id.lblCName);
lblContact = view.findViewById(R.id.lblContact);
clientitemslayout = view.findViewById(R.id.listclientsitems);
}
}
@Override
public void onBindViewHolder(ClientViewHolder holder, final int position) {
holder.lblName.setText(listOrders.get(position).getFNAME());
holder.lblRoute.setText(listOrders.get(position).getROUTE());
holder.lblType.setText(listOrders.get(position).CNIC);
holder.lblCName.setText(listOrders.get(position).getLNAME());
holder.lblContact.setText(listOrders.get(position).getCONTACT());
holder.clientitemslayout.setOnLongClickListener(new View.OnLongClickListener() {
@Override
public boolean onLongClick(View v) {
displayingAlertDialog(position);
return false;
}
});
}
@Override
public int getItemCount() {
Log.v(ClientRecyclerAdapter.class.getSimpleName(), "" + listOrders.size());
return listOrders.size();
}
private void displayingAlertDialog(final int position) {
final GetSetClientsDetail getSetClientsDetail= new GetSetClientsDetail();
AlertDialog.Builder builder = new AlertDialog.Builder(itemView.getContext());
builder.setTitle("Choose Option");
builder.setMessage("Add Client Invoice?");
builder.setPositiveButton("Add", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
gotInvoiceClass(listOrders.get(position).getFNAME());
dialog.cancel();
}
});
builder.setNeutralButton("Remove", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
//go to Remove Item
DatabaseHelper dbHelper = new DatabaseHelper(mContext);
dbHelper.deletePersonRecord(listOrders.get(position).getFNAME(), mContext);
listOrders.remove( position);
notifyItemRemoved(position);
notifyItemRangeChanged(position, listOrders.size());
notifyDataSetChanged();
dialog.cancel();
}
});
builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
});
AlertDialog alert11 = builder.create();
alert11.show();
}
private void gotInvoiceClass(String fname) {
Intent goToUpdate = new Intent (mContext,Invoices.class);
goToUpdate.putExtra("FIRSTNAME", fname);
mContext.startActivity(goToUpdate);
}
}
Я хочу перейти к другому классу пейджера представления, когда я нажму на диалоговое окно, которое я реализовал в своем классе адаптера.
Спасибо
