EditText log, mdp;
String login, pswrd;
Button blogin;
Button benregistrer;
Button bretour;


@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(activity_login);
blogin= (Button) findViewById(R.id.blogin);
blogin.setOnClickListener(this);
benregistrer= (Button) findViewById(R.id.benregistrer);
benregistrer.setOnClickListener(this);
log= (EditText) findViewById(R.id.log);
mdp=(EditText) findViewById(R.id.mdp);
bretour= (Button) findViewById(R.id.bretour);
bretour.setOnClickListener(this);
}
public void userlogin(View v) {
login = log.getText().toString();
pswrd = mdp.getText().toString();
backgroundtask task = new backgroundtask();
task.execute(login, pswrd);

}

@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.blogin:
userlogin(v);


break;

case R.id.bretour:
startActivity(new Intent(login.this, Bienvenue.class));
break;
case R.id.benregistrer:
Intent i = new Intent (login.this, MainActivity.class);
startActivity(i);

}

}

private class backgroundtask extends AsyncTask<String,Void,String> {
Context ctx;
AlertDialog alertdialog ;
protected String doInBackground(String... params) {

try {

String login= params[0].toString();
String motdepasse= params[1].toString();
String login_URL ="http://10.0.2.2/appandroid/login.php";
URL url = new URL(login_URL);
String data = URLEncoder.encode("username","UTF-8")+"="+URLEncoder.encode(login,"UTF-8");
data+= "&"+URLEncoder.encode("password","UTF-8")+"="+URLEncoder.encode(motdepasse,"UTF-8");

URLConnection httpURLConnection= url.openConnection();
httpURLConnection.setDoOutput(true);
OutputStreamWriter outputStream = new OutputStreamWriter(httpURLConnection.getOutputStream());
outputStream.write(data);
outputStream.flush();
BufferedReader bufferedReader= new BufferedReader(new InputStreamReader(httpURLConnection.getInputStream()));
StringBuilder sb = new StringBuilder();
String line =null ;

while ((line = bufferedReader.readLine())!=null )
{
sb.append(line);
break;

}

return sb.toString();

} catch (MalformedURLException e) {

Intent intent = new Intent(login.this,prives.class);
intent.putExtra(login, log.getText().toString());
startActivity(intent);
