我在XML代码或Java代码中看不到任何错误。

}

我遇到0个编译错误，但在Logcat中遇到运行时错误。

这是错误：

解决方法

您根本没有设置内容，因此所有findViewById都返回null ...

在调用setContentView之后（在所有super.onCreate之前）添加findViewById方法，指向发布的XML文件（R.layout.filename）

,

这是来自activity_main.xml文件中第88行的报告，我看到您的textColor指向一个字符串，您可以验证这一部分是否正确。

android:textColor="@string/fff"

它应该是一种颜色，即：

android:textColor="@color/colorAccent"

您可以发布自己的strings.xml吗？
