How to set font custom font to Spinner text programmatically?

Solution

This is what worked for me (using ideas both from CommonsWare's and gsanllorente's answers):

private static class MySpinnerAdapter extends ArrayAdapter<String> {
    // Initialise custom font, for example:
    Typeface font = Typeface.createFromAsset(getContext().getAssets(),
                        "fonts/Blambot.otf");

    // (In reality I used a manager which caches the Typeface objects)
    // Typeface font = FontManager.getInstance().getFont(getContext(), BLAMBOT);

    private MySpinnerAdapter(Context context, int resource, List<String> items) {
        super(context, resource, items);
    }

    // Affects default (closed) state of the spinner
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        TextView view = (TextView) super.getView(position, convertView, parent);
        view.setTypeface(font);
        return view;
    }

    // Affects opened state of the spinner
    @Override
    public View getDropDownView(int position, View convertView, ViewGroup parent) {
        TextView view = (TextView) super.getDropDownView(position, convertView, parent);
        view.setTypeface(font);
        return view;
    }
}

If you, like me, originally populated the Spinner using `ArrayAdapter.createFromResource()` and an array resource (as in Spinner documentation), then you'd use MySpinnerAdapter like this:

MySpinnerAdapter<String> adapter = new MySpinnerAdapter(
        getContext(),
        R.layout.view_spinner_item,
        Arrays.asList(getResources().getStringArray(R.array.my_array))
);
spinner.setAdapter(adapter);

Problem

I have a ttf font file in my assets folder. I know how to use it for textviews with: ``` Typeface externalFont=Typeface.createFromAsset(getAssets(), "fonts/HelveticaNeueLTCom-Lt.ttf"); textview1.setTypeface(externalFont); ``` I have defined look for my spinner text in it's own xml file (as usuall in android): ``` <?xml version="1.0" encoding="utf-8"?> <TextView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+android:id/text1" style="?android:attr/spinnerItemStyle" android:singleLine="true" android:textColor="#ffffff" android:gravity="center" android:layout_width="fill_parent" android:layout_height="wrap_content" android:ellipsize="marquee" /> ``` I just can't reference this textview from code, i always get null pointer exceptions. E.g. i tried: ``` TextView spinner_text=(TextView)findViewById(R.id.text1); spinner_text.setTypeface(externalFont); ``` Is it possible to select my external font even for my spinner text defined in it's own xml? Thank you. EDIT with answer: This works: ``` String [] items = new String[2]; items[0]="Something1"; items[1]="Something2"; ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.spinaca, items) { public View getView(int position, View convertView, ViewGroup parent) { View v = super.getView(position, convertView, parent); Typeface externalFont=Typeface.createFromAsset(getAssets(), "fonts/HelveticaNeueLTCom-Lt.ttf"); ((TextView) v).setTypeface(externalFont); return v; } public View getDropDownView(int position, View convertView, ViewGroup parent) { View v =super.getDropDownView(position, convertView, parent); Typeface externalFont=Typeface.createFromAsset(getAssets(), "fonts/HelveticaNeueLTCom-Lt.ttf"); ((TextView) v).setTypeface(externalFont); v.setBackgroundColor(Color.GREEN); return v; } }; adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); spinner.setAdapter(adapter); ``` It may be necessary to add ``` import android.view.ViewGroup; ``` To your list of imports at the top of your file. For some reason Eclipse doesn't make this suggestion when it doesn't recognize the ViewGroup class involved in the code.
