Erro ao ler contatos[RESOLVIDO]

kmunga · Março 24, 2013, 4:28pm

Estou encontrando problemas ao ler informações dos contatos, no exercicio que estou fazendo é para pegar o nome, numero telefonico e foto(se houver), mas ão esta dando certo. Já dei permissão para ler contatos.

Bom, o codigo é o citado abaixo:

[code]
package com.example.propriocap15;

import java.io.InputStream;

import android.app.Activity;
import android.content.ContentResolver;
import android.content.ContentUris;
import android.database.Cursor;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.net.Uri;
import android.os.Bundle;
import android.provider.ContactsContract;
import android.provider.ContactsContract.Contacts;
import android.widget.ImageView;
import android.widget.TextView;

public class PrincipalContatos extends Activity {

private String nomeContato;
private String numeroContato;
private static final long id=0;

@Override
public void onCreate(Bundle icicle){
	super.onCreate(icicle);
	setContentView(R.layout.principal_contatos);
	nomeContato=lerNome();
	numeroContato=lerNumero();
	TextView textoContato=(TextView) findViewById(R.id.nomeContato);
	textoContato.setText(nomeContato);
	TextView textoNumero=(TextView) findViewById(R.id.numeroContato);
	textoNumero.setText(numeroContato);
	defineImagem();
}

private void defineImagem() {
	// TODO Auto-generated method stub
	Uri uri=ContentUris.withAppendedId(Contacts.CONTENT_URI, id);
	ContentResolver contentResolver=getContentResolver();
	InputStream in=ContactsContract.Contacts.openContactPhotoInputStream(contentResolver, uri);
	if (in != null){
		ImageView imagemContato=(ImageView) findViewById(R.id.imagemContato);
		Bitmap imagem=BitmapFactory.decodeStream(in);
		imagemContato.setImageBitmap(imagem);
	}
}

private String lerNumero() {
	// TODO Auto-generated method stub
	Cursor cursor=
			getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null,
					ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "="+id, null, null);
	int coluna=cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
	String fone=cursor.getString(coluna);
	return fone;
}

private String lerNome() {
	// TODO Auto-generated method stub
	Uri uri=ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, id);
	Cursor cursor=getContentResolver().query(uri, null, null, null, null);
	String nome=cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME));
	return nome;
}

}[/code]

E o erro:

Olá
Antes de usar o cursor você precisa posicionar no primeiro registro

Modifiquei mas continua dando o erro

Normalmente checamos assim:

Para saber se existe registros retornados no cursor de acordo com o select

No caso, não tem registros o cursor está zerado. Erro ocorreu na linha 58.
