Question

I have a code that should make a "Post" via json ,but edittext is not converting to String,and there is no error in logcat .. Anyone have any idea of the mistake? It must be something stupid I apologize,.

public class PostTeste extends AppCompatActivity {


    private Button btnfincad;
    private EditText name,nick,email,password,number,sexo,tpativo;
   private String mName,mNick,mEmail,mPassword,mNumber,mSexo,mTpativo;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_cadastro);

        btnfincad = (Button) findViewById(R.id.btnfincad);
        nick = (EditText) findViewById(R.id.etnick);
        email = (EditText)findViewById(R.id.Cemail);
        password = (EditText)findViewById(R.id.Cpassword);
        number = (EditText)findViewById(R.id.etnumcel);
        sexo = (EditText)findViewById(R.id.sexo);
        tpativo = (EditText)findViewById(R.id.tpativo);


        btnfincad.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {


                btnfincad.setOnClickListener(new View.OnClickListener()
                {
                    public void onClick(View v) {
                        new onbuttonclickHttpPost().execute();
                        name = (EditText) findViewById(R.id.etname);
                        String mName = name.getText().toString();
                        String mNick = nick.getText().toString();
                        String mEmail = email.getText().toString();

Samara,

The error is occurring because you are declaring Strings twice, and also because you are sending it to the server as text, not as a variable.

Example:

You stated up there:

private String mName,mNick,mEmail,mPassword,mNumber,mSexo,mTpativo;

So when you use them, you don’t need to put String in front again.

Example:

mName = name.getText().toString();
mNick = nick.getText().toString();
mEmail = email.getText().toString();
mPassword = password.getText().toString();
mNumber = number.getText().toString();
mSexo = sexo.getText().toString();
mTpativo = tpativo.getText().toString();

That way you’ll already popular the variables you stated up there.

And finally, when sending them to the server, you don’t need the quotes.

Example:

postDataParams.put("email", mName);
postDataParams.put("password", mNick);
postDataParams.put("dt_nascimento", mData);
postDataParams.put("nu_cellphone", mNumber);
postDataParams.put("password", mPassword);
postDataParams.put("sexo", mSexo);
postDataParams.put("tp_ativo", mTpativo);

Notice that I removed the quotation marks from the second argument, which are the populated variables.

And give it a check, because you’re going twice to "password", one as mNick and another as mPassword, I believe only the second is right.

Something screams in there
