    @Override
    public void onCreate() {
        super.onCreate();
        application=this;
        initType();
    }

    private void initType(){
        Typeface typeface=Typeface.createFromAsset(getAssets(),"fonts/MicrosoftYaHei.ttf");
        Field field = null;
        try {
            field = Typeface.class.getDeclaredField("MONOSPACE");
            field.setAccessible(true);
            field.set(null,typeface);
        } catch (NoSuchFieldException e) {
            e.printStackTrace();
