今天，我尝试初始化“ ChatSDK”，但遇到了一些问题。现在，如果我想启动我的应用程序，那么它总是崩溃。我发现了这个问题：

我厌倦了在互联网上找到的所有修复建议，但没有任何效果:(。我希望你们能帮助我。 如果您需要我的MainActivity或我的grandle文件，请说出来！ 先感谢您！

不再支持Android支持库。因此，建议改用AndroidX Library。

使用AndroidX的FloatingActionButton：

1。添加gradle： 

implementation 'com.google.android.material:material:1.1.0'

2。添加您的布局： 

<com.google.android.material.floatingactionbutton.FloatingActionButton
    android:id="@+id/fab"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="end|bottom"
    android:src="@drawable/share_button"
    android:layout_margin="16dp" />

对于在2019年2月之后仍然存在此问题的任何人，如果您使用的是androidx或新的材料库，则会发生此问题，因为Google使用androidx更改了库的命名格式。您可以检查此正式映射{{ 3}} 并搜索您的库以查看新名称，因为Google位于androidx

在您的情况下，xml文件中的库“ android.support.design.widget.FloatingActionButton ”现在称为使用 com.google.android.material.floatingactionbutton。 FloatingActionButton

答案 2 :(得分：0)

您是否向项目添加了android支持库？如果没有尝试过这个：

implementation "com.android.support:design:28.0.0"

有关如何设置支持库的更多详细信息，您可以检查一下 https://developer.android.com/topic/libraries/support-library/setup

答案 3 :(得分：0)

将此添加到您的gradle中：

implementation com.android.support:design:28.0.0
