Question

我试图通过遵循

在android应用程序中应用自定义字体

https://developer.android.com/guide/topics/ui/look-and-feel/fonts-in-xml教程。

但是我收到“链接文件资源失败” 错误。我在res> font文件夹中有字体jameel_noori.ttf，字体资源文件jameel.xml具有android和app命名空间。请帮我我在做什么错了？

我的应用minsdkversion是17。我必须在片段中使用自定义字体。

这是我的字体资源文件jameel.xml

<?xml version="1.0" encoding="utf-8"?>

<!-- regular -->
<font
    android:font="@font/jameel_noori_regular"
    android:fontStyle="normal"
    android:fontWeight="400"

    app:font="@font/jameel_noori_regular"
    app:fontStyle="normal"
    app:fontWeight="400" />

<!-- italic -->
<font
    android:font="@font/jameel_noori_italic"
    android:fontStyle="italic"
    android:fontWeight="400"

    app:font="@font/jameel_noori_italic"
    app:fontStyle="italic"
    app:fontWeight="400" />

<!-- bold -->
<font
    android:font="@font/jameel_noori_bold"
    android:fontStyle="normal"
    android:fontWeight="700"

    app:font="@font/jameel_noori_bold"
    app:fontStyle="normal"
    app:fontWeight="700" />

片段布局文件fragment_single_dua.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"

    android:orientation="vertical">


           <TextView
            android:id="@+id/tv_urdu"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:gravity="right"
            android:lineSpacingExtra="10dp"
            android:paddingTop="6dp"
            android:text="@string/sample_arabic_text"
            android:textAlignment="gravity"
            android:textColor="@color/black"
            android:textSize="26sp"
            android:fontFamily="@font/jameel"/>



</LinearLayout>

这是我正在构建的错误：

error: failed linking file resources.

我在android:fontFamily="@font/jameel"中尝试过app:fontFamily="@font/jameel"和Textview，但错误仍然存在。

错误：链接文件资源以在Fragment中设置自定义字体失败
