Change TextSize of EditText programmically

To set TextSize of EditText, call its setTextSize() method.


package com.example.androidedittext;

import android.os.Bundle;
import android.app.Activity;
import android.widget.EditText;
import android.widget.SeekBar;
import android.widget.SeekBar.OnSeekBarChangeListener;
import android.widget.TextView;

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

final EditText input = (EditText)findViewById(R.id.input);
input.setTextSize(28);

SeekBar seekbarScale = (SeekBar)findViewById(R.id.sbsize);
final TextView textScale = (TextView)findViewById(R.id.textsize);

seekbarScale.setOnSeekBarChangeListener(new OnSeekBarChangeListener(){

@Override
public void onProgressChanged(SeekBar seekBar, int progress,
boolean fromUser) {
int size = progress+1;
input.setTextSize(size);
textScale.setText(String.valueOf(size));
}

@Override
public void onStartTrackingTouch(SeekBar seekBar) {
// TODO Auto-generated method stub

}

@Override
public void onStopTrackingTouch(SeekBar seekBar) {
// TODO Auto-generated method stub

}});

}

}

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" >

<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="android-coding.blogspot.com" />

<SeekBar
android:id="@+id/sbsize"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:max="50"
android:progress="28"/>

<TextView
android:id="@+id/textsize"
android:layout_width="match_parent"
android:layout_height="wrap_content" />

<EditText
