Set custom font for Android fragments

问题:

I have been using Jake Wharton's ViewPagerIndicator and I am currently trying to implement a custom font on one of my fragments. I've tried using this code:

   TextView txt = (TextView) findViewById(R.id.Zipcode);
    Typeface font = Typeface.createFromAsset(getAssets(), "fonts/customfont.ttf");
    txt.setTypeface(font); 

In the onCreate for the main activity which results in a null pointer exception in logcat and occasionally typeface cannot be made. I've also tried to set the font in the fragment itself in both the onCreate and onCreateView however findViewById and getAssests() are unknown methods in the fragment scope.

I'm having trouble figuring out if the font is the problem or where I am trying to set the fon't is the problem.

You can try this

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle     savedInstanceState) {
       View v = inflater.inflate(R.layout.fragment_layout, container, false);
       TextView txt = (TextView) v.findViewById(R.id.Zipcode);
       Typeface font = Typeface.createFromAsset(getActivity().getAssets(), "fonts/customfont.ttf");
       txt.setTypeface(font); 
       return v;
}

with this you can have the context in the scope of the fragment and get the view and the assets

回答2:

Define typeface in yourViewHolder class`

Typeface customFontBold= Typeface.createFromAsset(getActivity().getAssets(),"fonts/JosefinSans-Bold.ttf");

like this.

My Simple code is change method call "context" in the fragment with "getContext(); //is getContext and getActvity same in fragment??

**result**.setText("Value Expenses = " +expenses);
Typeface supercell = Typeface.createFromAsset(**getContext()**.getAssets(), "fonts/Supercell.ttf");**
**result.setTypeface(supercell);**
}catch (Exception e) 
{
Toast.makeText(getActivity(), "SUCCEED, VALUES RESULT", Toast.LENGTH_SHORT)
.show();
}
break;
