Android在整个项目中设置自定义字体

public class FontsOverride {    public static void setDefaultFont(Context context,String staticTypefaceFieldName, String fontAssetName) {        final Typeface regular = Typeface.createFromAsset(context.getAssets(),                fontAssetName);        replaceFont(staticTypefaceFieldName, regular);    }    protected static void replaceFont(String staticTypefaceFieldName,                                      final Typeface newTypeface) {        try {            final Field staticField = Typeface.class                    .getDeclaredField(staticTypefaceFieldName);            staticField.setAccessible(true);            staticField.set(null, newTypeface);        } catch (NoSuchFieldException e) {            e.printStackTrace();        } catch (IllegalAccessException e) {            e.printStackTrace();        }    }}

<resources>    <style name="AppBaseTheme" parent="android:Theme.Light">    </style>    <!-- Application theme. -->    <style name="AppTheme" parent="AppBaseTheme">        <item name="android:typeface">monospace</item>    </style></resources>

protected void onCreate(Bundle savedInstanceState) {        Log.e(TAG, "onCreate");        super.onCreate(savedInstanceState);        setContentView(R.layout.login_layout);        FontsOverride.setDefaultFont(this, "MONOSPACE", "FZLTXIHB.TTF");...}

主要思路是——通过设置theme将项目字体设为某种常见的字体（安卓本身自带的），然后通过一个函数将使用该字体的文字统一换成自定义的字体。
