从 XML 扩充 class NavigationView 时出错
Error inflating class NavigationView from XML
我在我的 MainActivity 中使用 NavigationView。现在，我的应用程序 运行 在 Android 5.0 及更高版本中运行良好。但是，Android 4.0.4 中没有 运行。它在 <NavigationView />.
中显示 XML 错误
我添加了 multidex 支持，认为它应该有所帮助。但是，它没有。
目前我在 NavigationView 中有 4 个图标，在 header_layout 中有 1 个启动器图标。所以，我认为不应该 OutOfMemoryError.
这是我的代码

现在，专注于第 1 行。 5.
android:background="@drawable/side_nav_bar"
就是渐变。
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient
android:angle="135"
android:endColor="?attr/colorPrimaryDark"
android:startColor="?attr/colorPrimary"

</shape>
我已经像这样更改了颜色值。
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient
android:angle="135"
android:endColor="@color/primary_dark"
android:startColor="@color/primary"
android:type="linear" />
</shape>
现在，运行 在 Android 2.3.3 模拟器上。
希望这对将来有所帮助。
感谢大家。
确保您对 Android 设计支持库具有正确的依赖性。很容易选错 - 因为似乎 Google postet 两个不同的依赖字符串：
在回答这个问题时，Android developer blog (and the comment by user hungryghost) had the correct dependency string, while the dependency string on the Support library 主页无法正常工作。
使用这个：编译'com.android.support:design:22.2.0'
注意版本是22.2.0（错误：22.0.0），包名是design（错误：support-design）
进行这些更改后，使用 Android Studio 菜单 "Rebuild project"，或更改 gradle 文件后有时会出现的 "Sync" 按钮。
我在我的 MainActivity 中使用 NavigationView。现在，我的应用程序 运行 在 Android 5.0 及更高版本中运行良好。但是，Android 4.0.4 中没有 运行。它在 <NavigationView />.
XML 错误
我添加了 multidex 支持，认为它应该有所帮助。但是，它没有。
目前我在 NavigationView 中有 4 个图标，在 header_layout 中有 1 个启动器图标。所以，我认为不应该 OutOfMemoryError.

终于找到了
第一个 这是我的 nav_header.xml 文件。
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="@dimen/nav_header_height"
android:background="@drawable/side_nav_bar"
android:gravity="bottom"
android:orientation="vertical"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:theme="@style/ThemeOverlay.AppCompat.Dark" >
<ImageView
android:id="@+id/imageView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:contentDescription="@string/app_name"
android:paddingTop="@dimen/nav_header_vertical_spacing"
android:src="@mipmap/ic_launcher" />
<TextView
android:id="@+id/tvNavUserFullName"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingTop="@dimen/nav_header_vertical_spacing"

<TextView
android:id="@+id/tvNavUserBalance"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/nav_sub_head" />
</LinearLayout>
现在，专注于第 1 行。 5.
android:background="@drawable/side_nav_bar"
就是渐变。
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient
android:angle="135"
android:endColor="?attr/colorPrimaryDark"
android:startColor="?attr/colorPrimary"
android:type="linear" />
</shape>
我已经像这样更改了颜色值。
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient
android:angle="135"
android:endColor="@color/primary_dark"
android:startColor="@color/primary"
android:type="linear" />
</shape>
现在，运行 在 Android 2.3.3 模拟器上。 希望这对将来有所帮助。 感谢大家。
确保您对 Android 设计支持库具有正确的依赖性。很容易选错 - 因为似乎 Google postet 两个不同的依赖字符串：
在回答这个问题时，Android developer blog (and the comment by user hungryghost) had the correct dependency string, while the dependency string on the Support library 主页无法正常工作。
使用这个：编译'com.android.support:design:22.2.0'
注意版本是22.2.0（错误：22.0.0），包名是design（错误：support-design）
进行这些更改后，使用 Android Studio 菜单 "Rebuild project"，或更改 gradle 文件后有时会出现的 "Sync" 按钮。
