Pessoal,
Estou tentando executar o seguinte comando :
SimpleCursorAdapter ad = new SimpleCursorAdapter(getBaseContext(),R.layout.spinner );
O problema que ele nao consegue achar o layout spinner
Qual erro do LogCat? Ao digitar R.layout.? Caso não apareca, verifica o import da classe R.
Esta dando o seguinte erro
int [] to = {R.id.txvid,R.id.txvnome,R.id.xvpreco};
erro :
Multiple markers at this line
- txvnome cannot be resolved or is not
a field
- xvpreco cannot be resolved or is not
a field
- txvid cannot be resolved or is not a
field
SimpleCursorAdapter ad = new SimpleCursorAdapter(getBaseContext(),R.layout.spinner, cursor, from, to);
erro :
Syntax error on tokens, delete these tokens
Obs.
Dei o add, para incluir no R.java o spinner.xml
Alguem pode me dar alguma luz ??
Segue abaixo minha classe completa

super.onCreate(savedInstanceState);
setContentView(R.layout.nova_venda);
Spinner spprodutos = (Spinner) findViewById(R.id.spprodutos);
SQLiteDatabase db = openOrCreateDatabase("vendas.db", Context.MODE_PRIVATE, null);
Cursor cursor = db.rawQuery("SELECT * FROM PRODUTOS", null);
String[] from = {"_id","nome","preco"};
int [] to = {R.id.txvid,R.id.txvnome,R.id.xvpreco};
@SuppressWarnings("deprecation")
SimpleCursorAdapter ad = new SimpleCursorAdapter(getBaseContext(),R.layout.spinner, cursor, from, to);
Button btnsalvar = (Button) findViewById(R.id.btnsalvar);
btnsalvar.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {

});

public void Salvar_Click(View view){

Verifica se existe a package com.example.vendas dentro da package Gen, a classe R.java está lá?
Inclui o import da classe R
import com.example.vendas.REsse import resolve esses erros.
int [] to = {R.id.txvid,R.id.txvnome,R.id.xvpreco};

Cliquei no Erro, e cliquei em ADD na minha classe R.
é isso mesmo ???
Olá
Tem erro na sua classe R, public static int spinner; <= falta o valor int para o spinner
Dá um clean para ver se funciona.
Ou verifica se não tem um erro no layout spinner
Deu certo consegui compilar.
obrigado
