At this link teaches to list comments (in my case news) using external database (has the project download).

How can I delete a news item when selecting, and still cause a dialog to appear asking if I want to delete the news from the external database?

This is the code of INSERT:

public void chamaCadastrarNoticia(){
    setContentView(R.layout.cadastrar_noticia);

    editTituloNoticia=(EditText) findViewById(R.id.editTituloNoticia);
    editNoticia=(EditText) findViewById(R.id.editNoticia);
    btCadastrarNoticia=(Button) findViewById(R.id.btCadastrarNoticia);

    btCadastrarNoticia.setOnClickListener(new View.OnClickListener() {
        public void onClick(View arg0) {                
            String vazios = "";
            if (editTituloNoticia.getText().toString().equals("")) 
                vazios="Campo Titulo não pode estar vazio\n\n"; 

            if (editNoticia.getText().toString().equals("")) 
                vazios="Campo Noticia não pode estar vazio\n\n";            

            if  (editTituloNoticia.getText().toString().equals("") || editNoticia.getText().toString().equals("")) 
                mensagemExibir("Erro:", ""+vazios);
            else {                
                String urlPost="#url"; // URL
                String urlGet="#url   ?titulo="+editTituloNoticia.getText().toString()+"noticia="+editNoticia.getText().toString(); // URL
                ArrayList<NameValuePair> iparametrosPost = new ArrayList<NameValuePair>();
                iparametrosPost.add(new BasicNameValuePair("titulo",editTituloNoticia.getText().toString()));   
                iparametrosPost.add(new BasicNameValuePair("noticia",editNoticia.getText().toString()));            
                String respostaRetornada = null;

                try {
                    respostaRetornada = ConexaoHttpClient.executaHttpPost(urlPost, iparametrosPost);
                    String resposta = respostaRetornada.toString();
                    resposta = resposta.replaceAll("\\s+", "");

                    if (resposta.equals("1")) {
                        mensagemExibir("Cadastrado:", "Acesse Listar Noticias para ver a noticia cadastrada");
                    }

                    chamaIndexAdmin();
                }
                catch(Exception erro){
                    Log.i("erro", "erro = "+erro);
                    mensagemExibir("Erro", "Erro ao gravar: "+erro);
                }
            }
        }
    });     
}

To submit a confirmation to the user you can use the Dialog, placing a request to the server on the positive button.

To delete a comment ( news, in your case ), I believe that the best option is to create a new service ( removeComment.php, for example ) that will be called and pass as parameter some identifier of the news ( recommend to be the own identifier of the table of the database )

From there just update the list on the device

  • in my case I created excluirNoticias.php but I try to implement the function of deleting it in Onitemclick and always from the error. Is there any way you could download the project and show me how it’s done? It only shows to list, now delete no =( last week it’s been 1 month that I’m trying and nothing, help me
