android - 支持设计库异常

Question

我正在尝试将抽屉导航添加到我的 Android 应用程序，但它不断抛出有关错误膨胀的错误。我也添加了支持库。 xml 文件不显示布局，它只显示灰色背景，上面写有 android.support.drawerlayout。就像找不到那个图书馆时一样。我尝试在互联网上搜索，但找不到任何可以帮助我的结果。

错误:

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.comsian.safetyalert/com.comsian.safetyalert.HomeActivity}: android.view.InflateException: Binary XML file line #2: Binary XML file line #2: Error inflating class android.support.v4.widget.DrawerLayout

Answer 1

如果你正在使用 androidx 然后使用

<androidx.drawerlayout.widget.DrawerLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"></androidx.drawerlayout.widget.DrawerLayout>

一旦这个工作也用androidx替换下面的依赖项

implementation 'androidx.appcompat:appcompat:1.0.2'
 implementation 'com.google.android.material:material:1.1.0-alpha08'
