package com.example.avi.myapplication;

import android.app.Activity;
import android.os.Bundle;
import android.widget.RelativeLayout;
import android.graphics.Color;
import android.widget.EditText;
import android.content.res.Resources;
import android.util.TypedValue;

public class MainActivity extends Activity {

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

        RelativeLayout myLayout = new RelativeLayout(this);

        myLayout.setBackgroundColor(Color.BLUE);

        EditText myText = new EditText(this);

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

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

        Resources r = getResources();
        int pixels = (int)TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP,
                                                    220,
                                                    r.getDisplayMetrics());
        myText.setWidth(pixels);

        myLayout.addView(myText, textParams);

        setContentView(myLayout);
    }
