import android.os.AsyncTask;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

    // Progress Dialog
    private ProgressDialog pDialog;

     String params;
    JSONParser jsonParser = new JSONParser();
    EditText inputCode;
    EditText inputLibelle;
    EditText inputDescription;
    EditText inputEtat;
    EditText inputAction;
    // url to create new product
    private static String url_create_rapport = "http://10.0.2.2/Scripts/Create_rapport.php";

    // JSON Node names
    private static final String TAG_SUCCESS = "success";

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

        // Edit Text
        inputCode = (EditText) findViewById(R.id.textView1);
        inputLibelle = (EditText) findViewById(R.id.textView2);
        inputDescription = (EditText) findViewById(R.id.textView3);
        inputEtat = (EditText) findViewById(R.id.textView4);
        inputAction = (EditText) findViewById(R.id.textView5);
        // Create button
        Button btnCreateRapport = (Button) findViewById(R.id.button1);

        // button click event
        btnCreateRapport.setOnClickListener(new View.OnClickListener() {
 String a;
 String b;
 String c;
 String d;
 String e;
            @Override
            public void onClick(View view) {

                a=inputCode.getText().toString();
                b=inputLibelle.getText().toString();
                c=inputDescription.getText().toString();
                d=inputEtat.getText().toString();
                e=inputAction.getText().toString();
                params="code="+a
                        +"&lib="+b
                        +"&desc="+c
                        +"&State="+d
                        +"&action="+c;
                CreateNewRapport t1= new CreateNewRapport();
                t1.execute(url_create_rapport,params);
            }
        });
    }

    /**
     * Background Async Task to Create new product
     * */
    class CreateNewRapport extends AsyncTask<String, String, String> {

        /**
         * Before starting background thread Show Progress Dialog
         * */
        @Override
        protected void onPreExecute() {
            super.onPreExecute();
            pDialog = new ProgressDialog(RapportActivity.this);
            pDialog.setMessage("Creating Rapport..");
            pDialog.setIndeterminate(false);
            pDialog.setCancelable(true);
            pDialog.show();
        }


        protected String doInBackground(String... params) {
            String s = HttpManager.posdata(params[0], params[1]);
            return s;

        }
        protected void onPostExecute(String s) {
            super.onPostExecute(s); 
            Toast.makeText(getApplicationContext(), s, Toast.LENGTH_SHORT).show();
        }

    }
}

$response = array();
$hostname_localhost ='localhost';
$port_localhost =5432;
$database_localhost ='techmobi';
$username_localhost ='openpg';
$password_localhost ='openpgpwd';
$localhost = "host='$hostname_localhost' port='$port_localhost' dbname='$database_localhost' user='$username_localhost' password='$password_localhost'";
$code_tech = $_REQUEST['code'];
$lib_int = $_REQUEST['lib'];
$desc_int = $_REQUEST['desc'];  
$etat_int = $_REQUEST['State'];
$action = $_REQUEST['action'];
$connexion =pg_connect($localhost) or die ("Erreur de connexion ".pg_last_error());
$query_search = "insert into rapport values('$code_tech','$lib_int','$desc_int','$etat_int','$action');";
$query_exec = pg_query($query_search) or die(pg_error());
// check if row inserted or not
    if ($result) {
        // successfully inserted into database
        $response["success"] = 1;
        $response["message"] = "requette successfully created.";

        // echoing JSON response
        echo json_encode($response);
    } else {
        // failed to insert row
        $response["success"] = 0;
        $response["message"] = "Oops! An error occurred.";

        // echoing JSON response
        echo json_encode($response);
    }
} else {
    // required field is missing
    $response["success"] = 0;

    // echoing JSON response
    echo json_encode($response);
}
?>

Answer 1

You try to cast TextView to EditText for R.id.textView3

It shows on your logcat, ClassCastException and it is caused by RapportActivity line 38
