我从这里使用最新版本的 ShowcaseView
当我尝试将它与演示应用程序和活动一起使用时,它可以工作,但是当我尝试将它与片段一起使用时,它使我的应用程序崩溃而没有 logcat 错误
@override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
final ImageButton saveButton = (ImageButton) view.findViewById(R.id.button_Save);
ViewTarget viewTarget = new ViewTarget(saveButton);
showcaseView = new ShowcaseView.Builder(getActivity())
.setTarget(viewTarget)
.setContentTitle("Reset Button")
.setContentText("This will erase all the data in the table except the line that in progress")
.build();
}
这里可能是什么问题?
编辑1:
当我尝试在我的fragmentactivity中做同样的事情并且没有工作时,但是当我做了同样的事情但采取了在fragmentactivity中声明而不是在它工作的片段中声明的视图时。
EDIT2: 我设法从 logcat 中得到错误。

我理解错误,但它的原因是什么?
