Question

设置自定义字体我通过扩展CutomTextView创建了TextView，但在使用RecyclerView时滚动时CutomTextView滞后。我尝试使用标准Textview并在ViewHolder中设置字体，但结果相同。

CustomTextView.java

public class CustomTextView extends TextView {

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

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

    public CustomTextView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        applyCustomFont(context);
    }

    private void applyCustomFont(Context context) {
        setTypeface(Typeface.createFromAsset(context.getAssets(), "fonts/hell.ttf"));
    }
}

Adapter.java

public class DashBoardAdapter extends RecyclerView.Adapter<DashBoardAdapter.ViewHolder> {

private List<PatientList> patientListList;
private Activity activity;

public DashBoardAdapter(List<PatientList> patientListList, Activity activity) {
    this.patientListList = patientListList;
    this.activity = activity;
}

@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View view = LayoutInflater.from(activity).inflate(R.layout.recyclerview_dashboard_row, parent, false);
    return new ViewHolder(view);
}

@Override
public void onBindViewHolder(ViewHolder holder, final int position) {
    final PatientList p = patientListList.get(position);
    if(p.getName() != null)
        holder.username.setText(p.getName());
}

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

class ViewHolder extends RecyclerView.ViewHolder{

    @BindView(R.id.patient_username) TextView username;
    private View itemView;

    public ViewHolder(View itemView) {
        super(itemView);
        this.itemView = itemView;
        ButterKnife.bind(this,itemView);

        // Setting font here when custom textview is not used
    }
}

@Override
public int getItemViewType(int position) {
    return position;
}

可能是滞后的原因？

每次使用字体时，您需要缓存字体并不需要初始化。

如果使用自定义字体，Recyclerview会滞后于滚动
