Modifying font in title causes error

Question

I've tried the first two answers in the following post for changing the font of my title: How to Set a Custom Font in the ActionBar Title? and I get the message in my emulator:

Unfortunately, DC Parks has stopped. OK

Going with the second answer here is my MainActivity code:

import android.app.ActionBar;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.text.Spannable;
import android.text.SpannableString;
import android.view.Menu;
import android.view.View;

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main); 

    SpannableString s = new SpannableString("My Title");
    s.setSpan(new TypefaceSpan(this, "MotorwerkOblique.ttf"), 0, s.length(),
            Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

    //Update the action bar title with the TypefaceSpan instance
    ActionBar actionBar = getActionBar();
    actionBar.setTitle(s);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

public void test(View view) {
    //Intent represents the app's 'intent to do something'
    Intent intent = new Intent(this, NewPage.class); //have to create the new_page activity
    startActivity(intent);
}

public void textclick(View myview) {
    Intent myintent = new Intent(this, NewPage.class);
    startActivity(myintent);
}
}

TypefaceSpan.java code:

public class TypefaceSpan extends MetricAffectingSpan {
/** An <code>LruCache</code> for previously loaded typefaces. */
private static LruCache<String, Typeface> sTypefaceCache =
new LruCache<String, Typeface>(12);

private Typeface mTypeface;

/**
* Load the {@link Typeface} and apply to a {@link Spannable}.
*/
public TypefaceSpan(Context context, String typefaceName) {
mTypeface = sTypefaceCache.get(typefaceName);

if (mTypeface == null) {
mTypeface = Typeface.createFromAsset(context.getApplicationContext()
.getAssets(), String.format("fonts/%s.otf", typefaceName));

// Cache the loaded Typeface
sTypefaceCache.put(typefaceName, mTypeface);
}
}

@Override
public void updateMeasureState(TextPaint p) {
p.setTypeface(mTypeface);
// Note: This flag is required for proper typeface rendering
p.setFlags(p.getFlags() | Paint.SUBPIXEL_TEXT_FLAG);
}

@Override
public void updateDrawState(TextPaint tp) {
 tp.setTypeface(mTypeface);
// Note: This flag is required for proper typeface rendering
tp.setFlags(tp.getFlags() | Paint.SUBPIXEL_TEXT_FLAG);
}
}

My font is located in assests/fonts/MotorwerkObliqhue.ttf

Any help would be greatly appreciated!

Answer 1

You're trying to use a ".ttf" font file, but the code expects an ".otf" font. If you remove the ".otf" portion of the file path it will work correctly.

Simply change this:

String.format("fonts/%s.otf", typefaceName)

to this:

String.format("fonts/%s", typefaceName)

You really need to post your logcat output though as it should show the actual error message.

Edit: To elaborate, in the original code the application is looking for a font file called assets/fonts/MotorwerkOblique.ttf.otf which probably doesn't exist. It expects you to just pass in the file name, without the extension.
