TextView上的addFontWeightStyle NoSuchMethodException

Question

我正在为项目使用 Androidx 库，并且我想为 textview 设置 font ，所以当我应用任何字体时而不是系统给我的任何 Textview 组件

  

TypefaceCompatApi21Impl：java.lang.NoSuchMethodException       java.lang.NoSuchMethodException：addFontWeightStyle [类java.lang.String，int，boolean]

这种类型的运行时错误，但应用没有崩溃。

那么如何克服这个错误。

注意：它将在没有android x依赖的情况下正常运行。

我的代码下方：

<androidx.appcompat.widget.AppCompatTextView
        android:id="@+id/menu_tv_title"
        style="@style/font_work_sans_medium"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="center"
        android:maxLines="1"
        android:ellipsize="end"
        android:paddingEnd="@dimen/_12sdp"
        android:paddingStart="@dimen/_12sdp"
        android:textColor="@android:color/black"
        android:textSize="17sp"
        android:gravity="center"
        tools:text="title"
        tools:visibility="gone"/>

这是样式

<style name="font_work_sans_medium" parent="@android:style/TextAppearance.Small">
    <item name="android:fontFamily">@font/work_sans_medium</item>
</style>

我还通过编程这样设置字体

var typeFace: Typeface? = ResourcesCompat.getFont(context, R.font.work_sans_bold)
    getTitleView().setTypeface(typeFace, Typeface.NORMAL)

仍然收到此错误

对于一些研究，我发现该解决方案可能对我有帮助，实际上我使用的是不稳定的alpha依赖项，因此我将AndroidX的lib版本降级了

我正在使用这种依赖性

您应该使用它代替

 implementation 'androidx.core:core-ktx:1.1.0-alpha04'
 implementation 'androidx.appcompat:appcompat:1.1.0-alpha02'

Answer 2

该问题已报告给Android team，并且似乎可以在将来的版本中解决：

根据以下版本的第25条评论

implementation 'androidx.appcompat:appcompat:1.1.0-alpha03'
implementation 'androidx.core:core-ktx:1.1.0-alpha05'

Answer 3

我从xml文件中删除了这一行，现在可以正常运行了

android:textStyle="bold"

关于 addFontWeightStyle 方法，该方法在API21 Impl中引发NoSuchMethodException

Answer 4

只需仔细阅读堆栈跟踪-这是AndroidX的问题。似乎androidx.core.graphics.TypefaceCompatApi21Impl()试图通过反射从框架类addFontWeightStyle(lass java.lang.String, int, boolean)内部的某个内部静态解析带有签名android.graphics.FontFamily的方法……事实证明该方法不存在。我在androidx.appcompat.widget.AppCompatAutoCompleteTextView中遇到了同样的问题。在Google修复之前，我们无能为力。

Answer 5

根据Class.java方法，显然该方法预期是公开的（或者如果不存在，我相信不是这样）并且不公开（请看下面的评论）：

private Method getMethod(String name, Class<?>[] parameterTypes, boolean recursivePublicMethods)
        throws NoSuchMethodException {
    if (name == null) {
        throw new NullPointerException("name == null");
    }
    if (parameterTypes == null) {
        parameterTypes = EmptyArray.CLASS;
    }
    for (Class<?> c : parameterTypes) {
        if (c == null) {
            throw new NoSuchMethodException("parameter type is null");
        }
    }
    Method result = recursivePublicMethods ? getPublicMethodRecursive(name, parameterTypes)
                                           : getDeclaredMethodInternal(name, parameterTypes);
    ***// Fail if we didn't find the method or it was expected to be public.***
    if (result == null ||
        (recursivePublicMethods && !Modifier.isPublic(result.getAccessFlags()))) {
        throw new NoSuchMethodException(name + " " + Arrays.toString(parameterTypes));
    }
    return result;
}

我相信这是Androidx中的一种错误。

Answer 6

尝试一下：

 <style name="CutsomFontTextView" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="android:fontFamily">@font/yourfont</item>
</style>

然后将此主题应用于如下所示的textview

<androidx.appcompat.widget.AppCompatTextView
    android:id="@+id/menu_tv_title"
    android:theme="@style/CutsomFontTextView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_gravity="center"
    android:maxLines="1"
    android:ellipsize="end"
    android:paddingEnd="@dimen/_12sdp"
    android:paddingStart="@dimen/_12sdp"
    android:textColor="@android:color/black"
    android:textSize="17sp"
    android:gravity="center"
    tools:text="title"
    tools:visibility="gone"/>

Answer 7

您的样式父项是@android:style/TextAppearance.Small，请点击该父项。您只会看到两项

<item name="textSize">14sp</item>
        <item name="textColor">?textColorSecondary</item>

因此错误是正确的。该样式内部没有fontFamily属性。

尝试将父主题更改为

<style name="font_work_sans_medium" parent="Base.Theme.AppCompat.Light.DarkActionBar">
 <item name="android:fontFamily">@font/work_sans_medium</item>
</style>

Answer 8

以编程方式设置字体时，您是否尝试过删除最后一个参数？

getTitleView().setTypeface(typeFace)

代替

getTitleView().setTypeface(typeFace, Typeface.NORMAL)

内部正在使用fontStyle

Answer 9

此处是编码的新手，但是如果您通过 Build /' Edit Libraries and Dependencies （编辑库和依赖项）”进入工具栏，然后单击建议，然后对 androidx.appcompat：appcompat：XXX 单击更新，它将解决该错误，而不是在build.gradle文件中进行：）
