Here is my script
package com.example.boby.myapplication;
import android.content.Context;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.net.HttpURLConnection;
import java.net.URL;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final Button Login = (Button) findViewById(R.id.buttonLogin);
final EditText username = (EditText) findViewById(R.id.UsernameID);
final EditText password = (EditText) findViewById(R.id.PasswordID);
Login.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
final Button Login = (Button) findViewById(R.id.buttonLogin);
final EditText username = (EditText) findViewById(R.id.UsernameID);
final EditText password = (EditText) findViewById(R.id.PasswordID);
String usernametext = username.getText().toString();
String passwordtext = password.getText().toString();
Context context = getApplicationContext();
String text = "";
if(usernametext.equals("") || passwordtext.equals(""))
{
text = "All Field required !!!";
int duration = Toast.LENGTH_SHORT;
Toast toast = Toast.makeText(context, text, duration);
toast.show();
}else{
goLogin(usernametext,passwordtext);
}
}
});
}
protected void goLogin(String username, String password){
HttpURLConnection connection;
OutputStreamWriter request = null;
String parameters = "username="+username+"&password="+password;
URL url = null;
int duration = Toast.LENGTH_SHORT;
String response;
try{
url = new URL("http://localhost/api/login/proses");
connection = (HttpURLConnection) url.openConnection();
connection.setDoOutput(true);
connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
connection.setRequestMethod("POST");
request = new OutputStreamWriter(connection.getOutputStream());
request.write(parameters);
request.flush();
request.close();
String line = "";
InputStreamReader isr = new InputStreamReader(connection.getInputStream());
BufferedReader reader = new BufferedReader(isr);
StringBuilder sb = new StringBuilder();
while ((line = reader.readLine()) != null)
{
sb.append(line + "\n");
}
response = sb.toString();
Toast toast = Toast.makeText(this, response, duration);
toast.show();
isr.close();
reader.close();
}
catch(IOException e)
{
Toast toast = Toast.makeText(this, "Error \n"+e, duration);
toast.show();
}
}
}
and here is my Codeigniter
class Login extends CI_Controller {
public function proses()
{
$username = $this->input->post("username");
$password = $this->input->post("password");
$result = $this->Modelmodel->check($username,$password);
json_encode($result);
}
}
class Modelmodel extends CI_Model {
public function check($username,$password)
{
return $this->db->query("select * from user where username = '".$username."' and password = '".$password."' ")->row();
}
}
sorry for my bad english
