在 Android 中膨胀 class android.support.v7.widget.Toolbar 时出错

Question

我查看了大量 SO 问题并尝试实施它们。似乎无法理解这一点，昨天还可以，但现在不行了。

Answer 1

我过去也遇到过类似的问题。 android:theme 是工具栏或 AppBarLayout 上的问题。

编辑：代码示例

<android.support.v7.widget.Toolbar
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        app:popupTheme="@style/AppTheme.PopupOverlay" />

选项2：

<style name="MyToolbar" parent="ThemeOverlay.AppCompat.Dark.ActionBar">
    <item name="android:background">@color/colorPrimary</item>
</style>

Answer 2

<style name="AppTheme" parent="@style/Theme.AppCompat.NoActionBar">
  <item name="windowActionBar">false</item>
  <item name="android:windowNoTitle">true</item>
</style>

试试这个主题片段

Answer 3

这是对我特别有用的。我的问题与主题无关，而是依赖项和 targetSdkVersion 的正确编译版本。更新了下面的 gradle 文件。更改了

原版Gradle

compile 'com.android.support:support-v4:24.0.0-alpha2'

已更改：

compile 'com.android.support:support-v4:23.0.0'

基本上问题是我的这个版本的库与其他版本和 minsdk 版本不匹配，所以有些东西没有很好地融合。一旦我更新了所有依赖项（特别是来自 google 设计库）以相互匹配，它就起作用了。
