I am unable to display the textviews and their contents on screen. The app does not crash but the debugger console displays this error. It shows that the causes are the following.
Caused by: android.view.InflateException: Binary XML file line #11: Binary XML file line #11: Error inflating class android.support.design.widget.BottomNavigationView
Caused by: android.view.InflateException: Binary XML file line #11: Error inflating class android.support.design.widget.BottomNavigationView
Caused by: java.lang.reflect.InvocationTargetException
Caused by: java.lang.RuntimeException: Unknown layout animation name: accelerateInterpolator
Moreover, the error points to setcontentview in the MainActivity. I have attempted solutions to the issue but to no progress. In fact I have higher version but this the error persists.

A snippet of the code that where I am adding the contents to this fragment.
bottomNavigationView.setOnNavigationItemSelectedListener { item ->
when(item.itemId){
R.id.nav_progress->
progressData()
R.id.nav_discover->
discoverData(arrItems)
R.id.nav_concept->
fetchData(arrItems, indices)
}
true
}
private fun progressData() {
var titles = listOf("first","second", "third","fourth")
val text1=findViewById<TextView>(R.id.quadrant1_textview1)
val text2=findViewById<TextView>(R.id.quadrant2_textview1)
val text3=findViewById<TextView>(R.id.quadrant3_textview1)
val text4=findViewById<TextView>(R.id.quadrant4_textview1)
text1?.text=titles[0]
text2?.text=titles[1]
text3?.text=titles[2]
text4?.text=titles[3]
}
The ProgressData() funtion is outside the oncreate.
Any help is appreciated.
The solution to this problem is that the view is not generated in the onCreate or OnCreateview. If we see the life-cycle of the fragment, we find that there is another method onViewcreated. The static code where the values are assigned to the text of the textviews must be placed in the onViewcreated method of the Progress fragment. This solved the problem.
The code snippet:
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
progress_progressbar2?.setProgress(12)
progress_progressbar2?.max=15
val currentProgress = progress_progressbar2?.progress ?: 0
if (currentProgress == 0){
started_image?.visibility = View.VISIBLE
progress_scrollview?.invalidate()
} else {
started_image?.visibility = View.GONE
progress_scrollview?.visibility = View.VISIBLE
navigation_header_container?.setImageResource(R.drawable.header_pink)
}
}
Thankyou YoLo for support. This worked for me.
