我有一个按钮类型的列表 TextView
就像在水平方向上 RecyclerView
我试图改变这些按钮文本的字体,但它不起作用。我改变了字体 XML
我的项目的exo文件,并试图使用许多提示,而不是查看 TextView
但是我不能改变字体。在使用时自定义视图有什么限制吗 RecyclerView
或者我做错了?
p、 我不能改变这个房间的填充物 TextView
任何一个。
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&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);
}
}
}
活动中回收器视图的实现:
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");
}
}

可以在viewholder构造函数中使用
Typeface.createFromAsset
```public class MyViewHolder extends RecyclerView.ViewHolder{
}
