二进制 XML 文件行 #2 为尝试动态实现主题而膨胀类 android.widget.RelativeLayout 时出错

问题描述 投票：0回答：4

我一直在尝试在我的项目中实现动态它们，但由于某种原因它给出了以下错误。这就是我尝试实现它的方式。

首先我定义了一些自定义属性，例如：

<resources>
<attr name="themeWindowBackground" format="reference" />
<attr name="themeContentBackground" format="reference" />
<attr name="themeContentTextColor" format="reference" />
<attr name="themeContentTextColorOnPrimary" format="reference" />
<attr name="themeTextColorSuccess" format="reference" />
<attr name="themeTextColorFailure" format="reference" />

然后我在 style.xml 文件中定义了自定义主题

<resources>

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

<style name="SplashTheme" parent="AppTheme">
    <item name="android:windowBackground">@drawable/bg_splash_screen</item>
</style>

<style name="AppTheme.Black" parent="AppTheme">
    <item name="colorPrimary">@color/material_dark</item>
    <item name="colorPrimaryDark">@color/material_primary_dark</item>
    <item name="colorAccent">@color/material_accent</item>
    <item name="themeWindowBackground">@color/dark_gray</item>
    <item name="themeContentBackground">@color/dark_slate_gray</item>
    <item name="themeContentTextColor">@color/white</item>
    <item name="themeContentTextColorOnPrimary">@color/teal</item>
    <item name="themeTextColorSuccess">@color/green</item>
    <item name="themeTextColorFailure">@color/red</item>
</style>
</resources>

之后我用这个设置主题

application.setTheme(mPreferenceRepository.savedTheme)

这是获取已保存主题的函数

public int getSavedTheme() {
    String theme = getStringFromSharedPreference(APP_THEME);
    if (theme.equals(THEME_BLUE)) {
        return R.style.AppTheme_Blue;
    }
    return R.style.AppTheme_Black;
}

现在当我尝试使用这个在我的布局或布局内容中应用主题时

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:background="?attr/themeWindowBackground"
android:layout_width="match_parent"
android:layout_height="match_parent">

应用程序崩溃。这是我的信息，但我不知道我做错了什么

如果您能给我一些指导，我将非常感激。非常感谢。

当我在旧的 Android 手机上测试我的应用程序时，我刚刚遇到了这个问题。不过它可以在新的 Android 手机上运行。我终于发现我将布局背景图像保存在 res\drawable-v24 中。删除图像并保存回 res\drawable

希望这能解决您的问题

我认为并且据我了解您的陈述，这个问题与RelativeLayout的第二行有关。尝试添加另一张图片到背景，或尝试输入 

android:background="?attr/themeWindowBackground"
` 作为风格。

像这样：

style =?attr/themeWindowBackround

这是一个老问题，但我还是决定回答一下。问题是您正在引用一个不存在的视图。

来自您的日志：

Binary XML file line #2: Error inflating class android.widget.RelativeLayout

您正在尝试夸大一个不存在的

RelativeLayout
。

当您添加横向布局而忘记添加 

RelativeLayout
时，可能会出现这种情况，或者可能是您引用了 id 不正确的 
RelativeLayout
。

确保 

RelativeLayout
确实存在，并且在引用它时使用了正确的 id。

当我像这样坐在后台时遇到此错误：

android:background="?attr/itemBackground"

其中：“itemBackground”未在主主题中定义...
