Ola Cristiana

de uma olhada neste topico

http://julianacora.blogspot.com.br/2012/04/android-passagem-de-parametros-entre.html

Ola! Boa noite.
Antes de mais obrigado pela atenção, podes me arranjar algum tutorial para ver como pego na listview o nome em vez do id?

Ola Cristiana

tente mudar

novo.putExtra("idObservation",cursor.getInt(cursor.getColumnIndex("_id")));

para isso

novo.putExtra("idObservation",cursor.getString(cursor.getColumnIndex("nome")));

Olá! obrigado pela dica e pelo tutorial, deu jeito!

Boa noite! Eu estive a ver o tutorial e a dica que me deste, e comecei a modificar o código.
No estanto na minha textview que é suposto receber o nome do aluno depois de clicado num item da listview, não acontece isso, aparece me o 1º nome do item da listview e não deixa ser alterado. podes m ajudar?

coloque um log.d depois

Cursor cursor .....

Log.d('idObservation",cursor.getString(cursor.getColumnIndex("_id"));

Log.d("idObservation", cursor.getString(cursor.getColumnIndex("nome"));

e coloque o resultado aki ...

e mostre tbm seu codigo pra ver como ficou...

Olha acontece que no textview deveria de aparecer o texto "Aluno" como está no ctos.xml, mas aparece o 1ºnome que está na lista e n altera caso escolha outro.

ola

em ctos

coloque o codigo

@Override
public void onResume(){

carregaEscolhaAluno();

}

depois do oncreate

Ola! com esta alteração o formulário Ctos não abre... da-m erro "unfortunately, ObservacaoObs has stopped."

tu comentou

carregaEscolhaObservador();

carregaEscolhaAluno();

do oncreate e da esse erro??

Ctos.java continuação

   private void carregaEscolhaObservador() {



        idAESObservation = getIntent().getIntExtra("idAESObservation", 0);



        datasource = new DBAdapter(this);

        datasource.open();

        aesobservation = datasource.getAESObservation(idAESObservation);

        datasource.close();

        observation = datasource.getObservation(idObservation);

        datasource.close();



        edtNomeA.setText(observation.getNome());



    }

}

pensei que fosse para comentar! já não tenho comentado!

deixa la comentado aqueles campos do oncreate

e faca isso...

private void carregaEscolhaObservador() {

if(it != null) {
Bundle params = it.getExtras();
if (params != null) {

idAESObservation = getIntent().getIntExtra("idAESObservation", 0);

aesobservation = datasource.getAESObservation(idAESObservation);
datasource.close();

edtNomeO.setText(aesobservation.getNome());

datasource = new DBAdapter(this);
datasource.open();
observation = datasource.getObservation(idObservation);
datasource.close();

edtNomeA.setText(observation.getNome());
}
}
}

olha ao escolher o aluno ou o observador na lista, dá o mesmo erro! =/

Mas a parte ótima é que já não dá erro ao abrir o formulário ctos!

comente o carregaEscolhaObservador();
do onResume

Sim já comentei! e continua o mesmo erro! mas agora é quando carrego num item da lista dos alunos ou do observador

coloque a classe EscolherObservador

        startActivity(novo);



    }

}

desculpa ...
pq eu num tava entendendo seu codigo.....

:)

idObservation = getIntent().getStringExtra("idObservation");

faca tbm

idAESObservation = getIntent().getStringExtra("idAESObservation");

Ponho essas linhas no Ctos.java no carregaEscolhaObservador() e carregaEscolhaAluno() ????

isso

e faça alteracao no DBAdapter

la no campo

public Observation getObservation (int idObservation){
Cursor cursor = database.query(dbHelper.TABLE_OBSERVATION, allColumnsObservation, dbHelper.ID " = " idObservation, null, null, null, null);
cursor.moveToFirst();
return cursorToObservation(cursor);
}

para esse

public Observation getObservation (String idObservation){
Cursor cursor = database.query(dbHelper.TABLE_OBSERVATION, allColumnsObservation, dbHelper.NOME " = " idObservation, null, null, null, null);
cursor.moveToFirst();
return cursorToObservation(cursor);
}

Ola bom dia! ontem tive de sair!
Mas olha já fiz as alterações, mas agora dá me este erro "Gradle: error: incompatible types" que seleciona a linha

idAESObservation = getIntent().getStringExtra("idAESObservation"); 

ola cristiana

mostre como é q ficou a classe ctos , dbadapter, escolherAluno...

e mostre log do erro

Ola! olha o erro já o descobri!!!
Mas infelizmente agora dá me outro!

dar o erro assim qdo tu carrega a aplicacao??

coloca esse erro entre
novo.putExtra e startActivity(novo)
no onListItemClick(ListView l, View v, int position, long id) esse codigo

coloque assim no DBAdapter....



Cursor cursor = database.query(dbHelper.TABLE_OBSERVATION, allColumnsObservation, dbHelper.NOME " = '" nomeObservation "'", null, null, null, null);

Mas queres que ponha isso na parte do aluno (Observation) ou na parte do observador (AESObservation) ???

olha dessa maneira dá-me erro "(Gradle: error: ')' expected"

e desta maneira já não dá

Cursor cursor = database.query(dbHelper.TABLE_OBSERVATION, allColumnsObservation, dbHelper.NOME   " = '"   nomeObservation   "'", null, null, null, null);

Mas em relação ao clicar no nome da lista seja no do aluno ou no do observador continua o mesmo erro e o emulador vai a baixo!

coloque nos dois

faca isso na classe EscolherAluno e EscolherObservador

//Log.d("idObservation", cursor.getString(cursor.getColumnIndex("nome")));

novo.putExtra("nomeObservation",nome);
startActivity(novo);

}
}

Ola bom dia!
Olha fiz a alteração mas o erro persiste...

No logcat error ao clicar "at com.example.observacaoobs.DBAdapter.cursorToAESObservation(DBAdapter.java:127)"

vai para a classe DBAdapter.java, para o método

private AESObservation cursorToAESObservation(Cursor cursor) {



        byte[] blob = cursor.getBlob(cursor.getColumnIndex(dbHelper.FOTO));

        ....

    }

e seleciona esta linha.

Não percebo porque dá erro aqui!!!

coloca log aqui

Boa tarde! tenho estado aqui as voltas com isto, ainda não viste nada?

Ola Cristiana..

Boa tarde.. como eu vou sair agora . .. coloque ai p mim

e por favor me de os xml e .java do EscolherAluno EscolherObservador e ObsActivity


o q faz o seu programa ??

tem q ter foto??

Bom dia Andre!
Olha isto é uma aplicação para escolas, onde os observadores prescrevem actividades e têm analisar e registar comportamentos dos alunos perante a atividade.
Inicialmente começo por um formulário para gravar dados pessoais sobre os observadores e os alunos, depois tenho os formulários para a descrição dos comportamentos dos alunos, um dos formulários chama-se Ctos e existe outros.
Antes da descrição dos comportamentos dos alunos, eu procuro o nome do observador que vai observar o aluno, e o nome do aluno, de seguida prossigo para a descrição do comportamento do aluno.

vc escolhe o aluno...

Vai para editar?? não percebi!
Eu queria que aparecesse o nome do aluno que vai ser avaliado o comportamento e o nome do observador que vai avaliar.

Isto porque há vários alunos e só avalio um de cada vez.

nao ...
eu to perguntando :)

vai p qual tela depois q tu lista aluno ??

Ah não tava a perceber! =)
Prontos eu listo os alunos na escolheraluno.xml e ao clicar no aluno pretendido, passar o nome para a textview da tela ctos.xml

mas pq tu nao passa o id??

pois mas eu tava a tentar fazer assim como tas a dizer, mas tava me a dar erro!!!

Olá bom dia!
Olha não sei se fiz bem ou, mas fiz o upload do ficheiro e deu-me este link!

Ola Bom dia

eu acho q vc precisa ler esse material aki

http://cesar.org.br/site/files/file/WM21_Android_Layouts.pdf

e ver o curso gratuito de android q tem aqui no site

pq vc esta errando no xml.....

Ola, antes de começar a fazer o projeto eu vi aqui o curso gratuito de android.
Ok, eu vou então seguir as tuas dicas, espero que continues a dar me uma ajudinha =) e obrigado!

Eu quero te ajudar, Cristiana...

por exemplo

xmlns:android="http://schemas.android.com/apk/res/android
isso vc declara em todos os LinearLayout de uma mesma tela , so um cara q manje muito (q nao sou eu, mas breve eu vou saber =D)
mexe assim na tela...

vc ja colocou no seu eclipse o graphical layout p ver se aparece la alguma tela??

pq eu copiei tudo q vc me passou e naum aparece nenhuma tela...

Olá bom dia Andre!
Olha estive a dar uma vista de olhos no tutorial, e a ver o meu código e realmente estava puxado, e sinceramente só agora percebi para que serva "xmlns:android="http://schemas.android.com/apk/res/android", e que só é necessário usar uma vez e no exterior do layout!!!
Mas em relação aos xml no graphical layout estava a funcionar, não me da erro!

Ola Cristiana

bom dia...

entaum copia pelo bloco de notas ai o xml escolheraluno e ctos... e me passa por favor

Já apaguei tudo, vou fazer de novo! Eu sou assim quando já há muita confusão faço de novo!
Olha já consigo passar o nome da listview (EscolherAluno.java e EscolherObservador.java) para o textview da Ctos.java, só mudei para chamar pelo id e foi a mudança no ctos.xml. Mas to com um problema!
Se no Ctos.java comentar a parte do observador o aluno funciona e se comentar a parte do aluno o observador também funciona! Mas se tirar o comentado tanto o aluno como o observador não está a funcionar!
