如何更改回收器视图中的字体

Question

我在水平RecyclerView中设置了一个类似按钮类型TextView的列表，我正在尝试更改这些按钮的文本字体，但它不起作用。我已经将项目的XML文件中的字体更改为exo，并尝试使用许多视图提示来代替TextView，但无论如何我都无法更改字体。当使用RecyclerView时，视图的自定义是否有任何限制，或者我做错了？

附言：我也不能更改TextView的填充。

我的RecyclerView项目：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="32dp">
<TextView
android:id="@+id/rpgListBtn"
android:layout_width="130dp"
android:layout_height="32dp"
android:layout_weight="1"
android:background="@drawable/ic_rpg_list"
android:fontFamily="@font/exo_teste"
android:gravity="center"
android:includeFontPadding="true"
android:paddingLeft="8dp"
android:paddingRight="8dp"
android:text="D&amp;D"
android:textAllCaps="false"
android:textColor="#000000"
android:textSize="13sp" />
</LinearLayout>

我的RecyclerView:

<androidx.recyclerview.widget.RecyclerView
android:id="@+id/rpgListView"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginTop="16dp"
android:clipToPadding="false"
android:paddingLeft="22dp"
android:paddingRight="8dp"
android:orientation="horizontal"
app:layoutManager="androidx.recyclerview.widget.LinearLayoutManager"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="@+id/escolha_um_" />

我的适配器：

package com.example.rpglink.Adapters;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
import androidx.annotation.NonNull;
import androidx.recyclerview.widget.RecyclerView;
import com.example.rpglink.R;
import java.util.List;
public class RpgListAdapter extends RecyclerView.Adapter<RpgListAdapter.MyViewHolder> {
private List<String> titulos;
public RpgListAdapter(List<String> titulos) {
this.titulos = titulos;
}
@NonNull
@Override
public MyViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
View itemLista = LayoutInflater.from(parent.getContext()).inflate(R.layout.rps_list_view_holder,parent,false);
return new MyViewHolder(itemLista);
}
@Override
public void onBindViewHolder(@NonNull MyViewHolder holder, int position) {
String titulo = titulos.get(position);
holder.titulo.setText(titulo);
}
@Override
public int getItemCount() {
return titulos.size();
}
public class MyViewHolder extends RecyclerView.ViewHolder{
TextView titulo;
public MyViewHolder(@NonNull View itemView) {
super(itemView);
titulo = itemView.findViewById(R.id.rpgListBtn);
}
}
}

活动中回收者视图的实现：

package com.example.rpglink.Activitys;
import androidx.appcompat.app.AppCompatActivity;
import androidx.recyclerview.widget.LinearLayoutManager;
import androidx.recyclerview.widget.RecyclerView;
import android.os.Bundle;
import com.example.rpglink.Adapters.RpgListAdapter;
import com.example.rpglink.Helpers.HorizontalSpaceItemDecoration;
import com.example.rpglink.R;
import java.util.ArrayList;
import java.util.List;
public class HomeC extends AppCompatActivity {
private RecyclerView recyclerView;
private RpgListAdapter adapter;
private List<String> lista = new ArrayList<>();
public HomeC() {
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home_c);
criarTitulos();
recyclerView = findViewById(R.id.rpgListView);
recyclerView.setHasFixedSize(false);
RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(getApplicationContext(), LinearLayoutManager.HORIZONTAL, false);
recyclerView.setLayoutManager(layoutManager);
adapter = new RpgListAdapter(lista);
recyclerView.setAdapter(adapter);
recyclerView.addItemDecoration(new HorizontalSpaceItemDecoration(32));

}
public void criarTitulos(){
this.lista.add("D&D");
this.lista.add("CyberPunk");
this.lista.add("Call of Cthulhu");
this.lista.add("Tormenta");
}
}

您可以使用Typeface.createFromAsset在ViewHolder构造函数中设置它

public class MyViewHolder extends RecyclerView.ViewHolder{
TextView titulo;
public MyViewHolder(@NonNull View itemView) {
super(itemView);
titulo = itemView.findViewById(R.id.rpgListBtn);
titulo.setTypeface(Typeface.createFromAsset(itemView.getContext().getAssets(), 
"font/exo_teste"));
}
}
