【问题描述】：

我为我的应用做了一个布局，它在 Nougat 及更高版本上运行良好，但无论出于何种原因，应用在 Android 6.0 上崩溃并出现以下错误：

此布局发生错误：

<com.google.android.material.card.MaterialCardView
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"

        <TextView

            android:textSize="24sp"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toTopOf="parent" />

问题出在&lt;TextView/&gt; 标签上。我不确定为什么会在 Marshmallow 而不是 Nougat+ 上发生这种情况（尚未测试棒棒糖，但我认为那里也出现了问题）。谁能解释一下？

更新：这里是HomeFragment.kt

package com.vanced.manager.ui.fragments
import android.content.Context
import android.net.ConnectivityManager
import android.net.Networkimport android.net.NetworkCapabilities
import android.net.NetworkRequestimport android.os.Bundle
import android.view.*import android.view.animation.Animation

import com.vanced.manager.R
import com.vanced.manager.adapter.SectionPageAdapter
import com.vanced.manager.core.fragments.Home 

class HomeFragment : Home() { 
    private lateinit var sectionPageAdapter: SectionPageAdapter
    private lateinit var viewPager: ViewPager2

    override fun onCreateView( 
        inflater: LayoutInflater, 
        container: ViewGroup?, 
        savedInstanceState: Bundle? ): 
    View? { 
        activity?.title = getString(R.string.title_home) 
        setHasOptionsMenu(true) return  
        inflater.inflate(R.layout.fragment_home, container, false) }

【问题讨论】：

  • Binary XML file line #20 第 20 行哪个？
  • 我包含了发生错误的布局xml代码。
  • 我知道。但是 xml 中的第 20 行是什么？
  • 第 20 行是 TextView 标签开始的地方
  • 注释掉没有解决问题，出现同样的错误

标签： android android-layout textview


【解决方案1】：

05-01 18:26:02.833 13123 13123 E AndroidRuntime: 原因: android.view.InflateException：二进制 XML 文件第 20 行：错误 膨胀类TextView

android:textColor="?colorPrimary" 调用 &lt;attr format="color" name="colorPrimary"/&gt;。如果您使用

，这将是一个好方法 
 android:textColor="@color/colorPrimary"  // call hex code from color xml

注意

似乎是您的 android:drawableStart="@drawable/ic_vanced" 引起了问题。请删除并运行。

然后Clean-Rebuild-Run。

【讨论】：

  • 谢谢大家，我会试试的
  • @Xinto 删除 app:cardBackgroundColor="?colorSurfaceVariant"
  • 使用srcCompat根本不显示logo，我想我得把logo移出textview
  • 哈哈，是啊...除了奇巧之外，我一直讨厌安卓 N 之前的版本，现在我有更多理由这样做了 xD
  • 不要这么认为，因为其他矢量绘图工作得很好，也检查了 gradle 构建文件，我确实指定了矢量绘图的使用
【解决方案2】：

在 textview 属性中

删除

 android:textColor="?colorPrimary"

添加

android:textColor="@color/colorPrimary"

【讨论】：

  • 好吧，我有 colorPrimary 作为属性，因为我有 2 个主题需要为 colorPrimary 单独颜色，我想根据主题更改该文本，这是唯一的变体吗？
  • 这种情况你应该在清单的活动标签中应用主题
