How to open font size options directly from intention?

Question

I would like the user to be able to edit the font and font style from my application. The application should simply call up the default settings.

Example:

 displayBtn = (Button) findViewById(R.id.displayBtn);
    displayBtn .setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            startActivity(new Intent(Settings.ACTION_DISPLAY_SETTINGS));
        }
    });

XML is not edited at run time, so you may need to set a static value for the font size, and then manually set them to applicaiton.

For instance..

public static int defaultFontSize = defaultValue;

//Update the value when the user changes font..
ClassName (class where you declared the static variable).defaultFontSize = 10;

textView.setTextSize(ClassName.defaultFontSize);
