item.xml

Question

我的问题是，所有recyclerview的任何项目内的任何文本视图都不会采用XML的字体，而只是显示android的原始字体

只有所有回收站视图的项目都存在此问题，其他文本视图可以正常工作

我在23 rv左右有很多回收站视图，并且还有更多视图，因此以编程方式更改每个文本字体不是一件好事我在这里没有运气尝试了很多事情有帮助吗？

这是一个示例：适配器视图

import android.content.Context
import android.util.Log

import android.view.LayoutInflater
import android.view.View
import android.view.ViewGroup
import android.widget.ImageView
import androidx.recyclerview.widget.RecyclerView
import com.ecom.R
import com.ecom.data.model.FabricProduct
import com.squareup.picasso.Picasso
import kotlinx.android.synthetic.main.item_fabric_product.view.*


class CollectionAdaptor(var mList: List<FabricProduct>, var context: Context, val listener: (FabricProduct) -> Unit
) : RecyclerView.Adapter<CollectionViewHolder>() {

    fun updateList(newitems: List<FabricProduct>) {
        mList = newitems
        notifyDataSetChanged()
   }

    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): CollectionViewHolder {return CollectionViewHolder( LayoutInflater.from(context).inflate(R.layout.item_fabric_product,parent,false))
}

    override fun onBindViewHolder(holder: CollectionViewHolder, position: Int) {
        holder.bind(mList[position], listener)

    }

    override fun getItemCount(): Int {
        return mList.size
    }}

class CollectionViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
    fun bind(item: FabricProduct, listener: (FabricProduct) -> Unit) = with(itemView) {
        itemView.text_subcategorie_slogan.text = item.slogan
        itemView.text_subcategorie_title.text = item.title
        setOnClickListener { listener(item) }
    }}

recyclerview设置

mFabricProductlist = FakeData.getFabricCollection()

            rootView.rv_collection_subcategory.layoutManager = GridLayoutManager(activity!!.applicationContext, 2)

            mCollectionAdaptor =
                CollectionAdaptor(mFabricProductlist as List<FabricProduct>, activity!!.applicationContext) { //get the selected item here}

     rootView.rv_collection_subcategory.adapter = mCollectionAdaptor

在fragment_collection.xml内部

<androidx.recyclerview.widget.RecyclerView
            android:id="@+id/rv_collection_subcategory"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
    />

item.xml

        <TextView

            android:textColor="@color/white"
            android:textSize="16sp" />

        <TextView
            android:id="@+id/text_subcategorie_slogan"

            android:textAllCaps="false"
            android:textColor="@color/white"
            android:textSize="12sp" />

Answer 1

它现在正在工作，问题是

mCollectionAdaptor =
                CollectionAdaptor(mFabricProductlist as List<FabricProduct>, activity!!.applicationContext) { //get the selected item here}

我通过了活动的applicationContext，所以解决方案只是通过了活动

 mCollectionAdaptor =
                    CollectionAdaptor(mFabricProductlist as List<FabricProduct>, activity!!) { //get the selected item here}

谢谢

Answer 2

使用 AppCompatTextView 而不是 TextView

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="220dp"
    android:layout_marginStart="15dp"
    android:layout_marginTop="4dp"
    android:layout_marginEnd="15dp"
    android:layout_marginBottom="4dp"

    >
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom"
        android:layout_margin="10dp"
        android:layout_marginStart="4dp"
        android:orientation="vertical">


        <androidx.appcompat.widget.AppCompatTextView
            android:id="@+id/text_subcategorie_title"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            app:fontFamily="@font/montserrat_bold"
            android:shadowColor="#000"
            android:shadowDy="1"
            android:shadowRadius="1"
            android:text="000"
            android:textAllCaps="false"
            android:textColor="@color/white"
            android:textSize="16sp" />

        <androidx.appcompat.widget.AppCompatTextView
            android:id="@+id/text_subcategorie_slogan"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            app:fontFamily="@font/montserrat"
            android:shadowColor="#000"
            android:shadowDy="1"
            android:shadowRadius="2"
            android:text="000"
            android:textAllCaps="false"
            android:textColor="@color/white"
            android:textSize="12sp" />


    </LinearLayout>

</FrameLayout>

字体不会针对recyclerview项目内的textview更改，仅适用于整个应用

recyclerview设置

在fragment_collection.xml内部

item.xml

build.gradle

2 个答案:

我通过了活动的applicationContext，所以解决方案只是通过了活动
