您好，我正在尝试使用此布局启动 Activity，但它仅适用于 Android 5+，当我在旧版本上运行它时，它总是会崩溃。这可能是什么原因造成的？也许我正在使用一些受限制的 android 版本 <5 xml 字段？

最佳答案
关于android的问题，不知道该选哪个主题。这是前 Lollipop 和后 Lollipop 设备之间的冲突，因此我们需要明确转换为无操作栏主题。添加
编译'com.android.support:appcompat-v7:24.2.0'
这里我的案例是 v24，选择您方便的版本。为了定义 Lollipop 之前的设备，我们更改了 res/values/style.xml 中的样式方案，如下所示:
<!-- Base application theme. -->
<style name="AppTheme.Base" parent="Theme.AppCompat.Light.NoActionBar">
</style>
<style name="AppTheme" parent="AppTheme.Base">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
</style>
AppTheme 继承自AppTheme.Base 它继承自Theme.AppCompat.Light.NoActionBar。所以在这里我们可以在这里提及我们支持的 Lollipop 前设备的配色方案。就是这样:)
Lollipop 设备支持的 Material 设计。我们可以在这里添加更多的配色方案。我们已经在res/values/styles.xml 中定义了AppTheme。
现在从 res/values/values/styles.xml 继承相同的 AppTheme 到 res/values/values-v21/styles.xml。所以 Values-v21/styles.xml 如下:
<style name="AppTheme" parent="AppTheme.Base">
<!-- Customize your theme here. -->
<item name="android:colorPrimary">@color/colorPrimary</item>
<item name="android:colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="android:colorAccent">@color/colorAccent</item>
<item name="android:textColorPrimary">@color/colorPrimary</item>
<item name="android:windowBackground">@color/colorAccent</item>
<item name="android:navigationBarColor">@color/colorPrimary</item>
</style>
试试这个。 :-)
