Possible Duplicate: How to change the Font Size in a whole Application programmatically, Android? This is my Code : I have created Spinner with a list of FontSize options. If I

Solution 1:

to change

textSize use editText.setTextSize(20)

font and style use editText.setTypeface(yourTypeFace, Typeface.BOLD)

UPDATE

public class MyEditText extends EditText{

public MyEditText(Context context) {
    super(context);
    init();
}

public MyEditText(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
    init();
}
public MyEditText(Context context, AttributeSet attrs) {
    super(context, attrs);
    init();
}
void init() {
   this.setTextSize(20);
   this.setTypeface(yourTypeFace, Typeface.BOLD);
}

// method to change font settings
void setFont(TypeFace tf){
   this.setTypeFace(tf);
}
//add whatever method you want
}

and then instead of using EditText you use this class, and don't forget in your XML to use

<yourpackage.MyEditText
     android:layout_height=".."
     android:layout_width=".."
     ... />

Solution 2:

The probable solution would be you create a base class which extends TextView, and use this text view class as edit text. Hope you are asking for size in first screen. In any case, u set the text size in the base class. This will solve your problem.

like u create this class in package com.example and class name is BaseTextView, then in xml file instead of you will write

Hope this helps.

Solution 3:

First of all get the id of the EditBox. Then selected item's position. according to that you can make a formula like this:

public void onItemSelected(AdapterView<?> arg0, View arg1,int position, long id) {
    int p=(8+(pos*2));

    editText.setTextSize(p);
}
