import android.graphics.drawable.AnimationDrawable;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;

public class LoginActivity extends RoboActivity {
    Application app;
    private TextView useridView;
    private TextView passView;
    private Button loginBtn;
    private String buttonLabel;
    private ImageView loading;
    private boolean closeApp=true;


    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_login);
        app = (Application) getApplication();
        useridView = (TextView) findViewById(R.id.useridEdTxt);
        passView = (TextView) findViewById(R.id.passEdTxt);
        loginBtn = (Button) findViewById(R.id.userLoginBtn);
        loading = (ImageView) findViewById(R.id.login_loading);
    }

    @Override
         protected void onPause() {
        super.onPause();
        finish();
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        if (closeApp)
        app.stopServices();
    }

    public void doLogin(View view){
//        hideKeyboard(view);
        if (!app.isNetworkAvailable()){
            Toast.makeText(this, "Tidak terhubung ke internet. Pastikan koneksi data telah tersambung.", Toast.LENGTH_LONG).show();
            return;
        }
        if (useridView.getText().equals("") || passView.getText().equals("")){
            Toast.makeText(this, "Silakan isi dengan data yang benar", Toast.LENGTH_LONG).show();
            return;
        }

        loginBtn.setEnabled(false);
        buttonLabel = String.valueOf(loginBtn.getText());
        startLoading();
//        ... ... ...
    }

    private void startLoading() {
        loading.setVisibility(View.VISIBLE);
        ((AnimationDrawable)loading.getBackground()).start();
    }

    private void stopLoading() {
        loading.setVisibility(View.INVISIBLE);
        ((AnimationDrawable)loading.getBackground()).stop();
    }

}
