Ich habe eine benutzerdefinierte Schriftart für meine Android-Aktivität.

MainActivity.class

    private void initControls() {
    // TODO Auto-generated method stub
    header = (TextView) findViewById (R.id.tvAccommodations);
    lv = (ListView) findViewById (R.id.lvAccommodations);
    text = (TextView) findViewById (R.id.textView);

    Typeface tf = Typeface.createFromAsset(getAssets(),
            "fonts/heartbre.ttf");
    header.setTypeface(tf);
    text.setTypeface(tf);



    ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this,
                    R.array.abra_hotel, R.layout.custom_list_text);
            lv.setAdapter(adapter);
            header.setText(value);

custom_list_text.xml

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/list_text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textSize="18sp"
android:textStyle="bold"
android:text="@string/app_name"
android:paddingLeft="6dip" />

Android löst eine NullPointerException aus. Wieso ist es so? Jede Hilfe wird geschätzt. Vielen Dank.
