我如何在片段布局中使用自定义字体

Question

*Edit

我认为它必须与Android 5.0.2做一些事情。我尝试了一个活动，它给了我同样的错误。

所以我是新的导航抽屉和片段。一切都很好，现在我想有一个textview自定义字体。通常情况下，它与下面的方法一起工作，但现在不行了。

public class HomeFragment extends Fragment {
public HomeFragment(){}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    // I use this everytime for normal layouts, but with a fragment layout it doesnt work
    TextView txt = (TextView) findViewById(R.id.textViewHome);  
    Typeface font = Typeface.createFromAsset(getAssets(), "impact.ttf");  
    txt.setTypeface(font); 

    View rootView = inflater.inflate(R.layout.fragment_home, container, false);
    return rootView;

}
}

我得到的错误是:

The method getAssets() is undefined for the type HomeFragment
The method findViewById(int) is undefined for the type HomeFragment 

由于我是android编程的新手，我真的想要一个解决方案，并想了解为什么它是错误的。非常感谢所有的帮助!

Answer 1

您只需要更改一些东西。在获得子视图之前，您需要首先膨胀视图，并且还需要获得活动来获取资产:

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

    View rootView = inflater.inflate(R.layout.fragment_home, container, false);
    TextView txt = (TextView) rootView.findViewById(R.id.textViewHome);  
    Typeface font = Typeface.createFromAsset(getActivity().getAssets(), "impact.ttf");  
    txt.setTypeface(font); 
    return rootView;

}
}

Answer 2

修改一下就行了

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

TextView txt = (TextView) findViewById(R.id.textViewHome);  
Typeface font = Typeface.createFromAsset(getActivity().getAssets(), "impact.ttf");  
txt.setTypeface(font); 

View rootView = inflater.inflate(R.layout.fragment_home, container, false);
return rootView;
 }
                                         }

这里getActivity()将给你上下文，从这个上下文你可以访问资产文件夹。它会工作的:)

尝试在字体中添加s，如assets/fonts
