How do I call findViewWithTag in the OnCreate() method of an activity?
android
Solution
`findViewWithTag()` is only defined for a View.
If you have a reference to the contentView of the activity that you set with `setContentView(contentView)`, you can use `contentView.findViewWithTag()`.
If you don't have a reference to that view, you can also use `findViewById(R.id.your_content_view_id).findViewWithTag(tag)`.
Problem
I get an error when I call `findViewWithTag()` in the `onCreate()` "The method `findViewWithTag(String)` is undefined for the type MainActivity" Is there any alternative?
