How to set font custom font to Spinner text programmatically?

Question

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.

Answer 1

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); 

Answer 2

You would apply the font through your own custom SpinnerAdapter, in getView() and getDropDownView().
