片段使用滑动视图appcompat的资产

Question

我正在使用片段而且我无法使用这些资产来更改我的信件。我正在使用appcompat的滑动页面。这是我的代码：

public class AcercaFragment extends Fragment {
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {

        View view = inflater.inflate(R.layout.acerca, container, false);
        TextView logouno = (TextView) getView().findViewById(R.id.logouno);
        Typeface typeface = Typeface.createFromAsset(getActivity()
                .getAssets(), "fonts/Roboto-Thin.ttf");
        logouno.setTypeface(typeface);

        return view;
    }
}

Answer 1

尝试这个小小的改变：

public class AcercaFragment extends Fragment {
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {

        View view = inflater.inflate(R.layout.acerca, container, false);
        TextView logouno = (TextView) view.findViewById(R.id.logouno);
        Typeface typeface = Typeface.createFromAsset(getActivity()
                .getAssets(), "fonts/Roboto-Thin.ttf");
        logouno.setTypeface(typeface);

        return view;
    }
}

您应用字体的方式还可以，但您必须从视图view获取TextView。

Answer 2

您无法在getView()方法中访问onCreateView的观看次数。在这里，您应该只返回一个膨胀的视图：

 @Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) 
{
    return inflater.inflate(R.layout.acerca, container, false);
}

然后，初始化UI元素，如下所示：

@Override
public void onActivityCreated(Bundle savedInstanceState)
{
    super.onActivityCreated(savedInstanceState);
    TextView logouno =(TextView) getView().findViewById(R.id.logouno);
    Typeface typeface = Typeface.createFromAsset(getActivity().getAssets(), "fonts/Roboto-Thin.ttf");
    logouno.setTypeface(typeface);
}
