Android method parametre as array

Question

public void setFont(String font_type, TextView[] fontArray)
{
    Typeface face = Typeface.createFromAsset(getAssets(), "fonts/" + font_type);

    for (int i = 0; i < fontArray.length; i++){
        fontArray.setTypeface(face);
    }
}

I want to add different textviews to different typeface. i could not find out how to implement foreach loop correctly.

I'm not sure I get the question. You need to access each element of the font array--maybe brushing up on some Java basics would be a good idea. Also, `for (TextView textView : textViews)` would make more sense than calling it `fontArray`, since it's not an array of fonts. — Dave Newton, Mar 06 '13 at 14:37

You are missing the index in the loop:

fontArray[i].setTypeface(face);
         ^^^
      add this

...or use a "for each" (as you wanted):

for (TextView tv : fontArray)
    tv.setTypeface(face);

Like any other Java array, you can iterate over its elements using a for-loop

for(TextView tv: fontArray) {
    tv.setTypeface(face);
}

See Java: Array with loop for another example.

Note, the name fontArray is a bit misleading... You could rename it to textViews or something more appropriate...
