该错误是由以下命令触发的：
setContentView(R.layout.activity_item_list);
此代码由android studio生成，当使用“主/从流”创建新的android项目时
似乎布局已渲染，但仍然出现错误

如前所述，该代码是由Android Studio 3.2.1自动生成的，并选择“活动”的“主/明细流”类型

您应该将以下内容粘贴到项目的底部-build.gradle
// This is to fix the errors : java.lang.NoClassDefFoundError: Failed resolution of: Landroid/view/View$OnUnhandledKeyEventListener;
configurations.all {
resolutionStrategy.eachDependency { details ->
def requested = details.requested
if (requested.group == "com.android.support") {
if (!requested.name.startsWith("multidex")) {
details.useVersion "26.+"
}
}
}
}
