package com.example.avi.myapplication;

import android.app.Activity;
import android.os.Bundle;
import android.widget.RelativeLayout;
import android.widget.Button;
import android.graphics.Color;
import android.widget.EditText;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        RelativeLayout myLayout = new RelativeLayout(this);
        Button myButton = new Button(this);


        myLayout.setBackgroundColor(Color.BLUE);

        myButton.setBackgroundColor(Color.GREEN);
        myButton.setText("Login");

        RelativeLayout.LayoutParams buttonParams =
                new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT,
                                                RelativeLayout.LayoutParams.WRAP_CONTENT);

        buttonParams.addRule(RelativeLayout.CENTER_HORIZONTAL);
        buttonParams.addRule(RelativeLayout.CENTER_VERTICAL);

        myLayout.addView(myButton, buttonParams);

        EditText myText = new EditText(this);

        myButton.setId(1);

        RelativeLayout.LayoutParams textParams =
                new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT,
                                                RelativeLayout.LayoutParams.WRAP_CONTENT);

        textParams.addRule(RelativeLayout.ABOVE, myButton.getId());
        textParams.addRule(RelativeLayout.CENTER_HORIZONTAL);
        textParams.setMargins(0, 0, 0, 60);

        myLayout.addView(myText, textParams);

        setContentView(myLayout);
    }
}
