我收到一個錯誤，當我在RecyclerView中使用自定義字體時

Question

它是一個非常基本的RecyclerView列表應用程序，包含兩個TextView和一個使用ArrayList類拉取數據的ImageView。有用。但我想用其中一個TextView設置自定義字體。我可以在哪裏放置「字體代碼」？

主要活動

public class MainActivity extends ActionBarActivity { 

    private RecyclerView mRecyclerView; 
    private RecyclerView.Adapter mAdapter; 
    private RecyclerView.LayoutManager mLayoutManager; 



    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     mRecyclerView = (RecyclerView) findViewById(R.id.my_recycler_view); 


     mRecyclerView.setHasFixedSize(true); 


     mLayoutManager = new LinearLayoutManager(this); 
     mRecyclerView.setLayoutManager(mLayoutManager); 





     ArrayList<AllList> list = new ArrayList<AllList>(); 


     list.add(new AllList("test","description",R.drawable.arrow)); 

     mAdapter = new MyAdapter(list); 
     mRecyclerView.setAdapter(mAdapter); 
    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 

     getMenuInflater().inflate(R.menu.menu_main, menu); 
     return true; 
    } 

    @Override 
    public boolean onOptionsItemSelected(MenuItem item) { 

     int id = item.getItemId(); 


     if (id == R.id.action_settings) { 
      return true; 
     } 

     return super.onOptionsItemSelected(item); 
    } 
} 

適配器類

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> { 
    private ArrayList<AllList> list; 
    Typeface ef; 
    Context c; 


    public static class ViewHolder extends RecyclerView.ViewHolder { 

     public View View; 
     public ViewHolder(View v) { 
      super(v); 
      View = v; 
     } 
    } 


    public MyAdapter(ArrayList<AllList> duas) { 


     this.list = duas; 
    } 


    @Override 
    public MyAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, 
                int viewType) { 

     View v = LayoutInflater.from(parent.getContext()) 
       .inflate(R.layout.row, parent, false); 



     ViewHolder vh = new ViewHolder(v); 

     return vh; 
    } 


    @Override 
    public void onBindViewHolder(ViewHolder holder, int position) { 


     TextView title = (TextView) holder.View.findViewById(R.id.title); 
     TextView desc = (TextView) holder.View.findViewById(R.id.desc); 
     ImageView imageView = (ImageView) holder.View.findViewById(R.id.imageView); 


//  Typeface cfont = Typeface.createFromAsset(getContext().getAssets(), "fonts.h.ttf"); 
//  this.ef = cfont; 
// 
////  title.setTypeface(ef); 

     title.setText(list.get(position).getTitle()); 
     desc.setText(list.get(position).getDesc()); 

    } 


    @Override 
    public int getItemCount() { 
     return list.size(); 
    } 
}

使用此代碼

public class CustomTextView extends TextView { 

public CustomTextView(Context context, AttributeSet attrs, int defStyle) { 
    super(context, attrs, defStyle); 
    createFont(); 
} 

public CustomTextView(Context context, AttributeSet attrs) { 
    super(context, attrs); 
    createFont(); 
} 

public CustomTextView(Context context) { 
    super(context); 
    createFont(); 
} 

public void createFont() { 
    Typeface font = Typeface.createFromAsset(getContext().getAssets(), "roboto_light.ttf"); 
    setTypeface(font); 
} 
} 

使用這個類在XML

<CustomTextView 
    android:id="@+id/title" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
/> 

最後，你必須使用這個textview只是初始化和使用它

CustomTextView title = (CustomTextView) findViewById(R.id.title); 
title.setText("Enjoy!!");
