I use MotionLayout to collapse/expand header in toolbar. I want to be able to expand/collapse my header even also by swiping textview R.id.toolbar_title, but now this OnSwipe on main_activity_scene.xml concenring the parent (R.id.ll_toolbar) of this TextView R.id.toolbar_title seems to be hidden by onClickListener and this swipe gesture not work on this TextView. But this view is a part of R.id.ll_toolbar so I want this TextView also to be able to swipe.
I hope you understand.
Here is my code:
MainActivity.kt
class MainActivity : AppCompatActivity(), OnChangeFragment {
private lateinit var toolbarSubtitle: TextView
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.main_activity)
initToolbarMembers()
changeFragment(CurrencyListFragment(), ChangeFragmentData())
}
override fun changeFragment(fragment: Fragment, changeFragmentData: ChangeFragmentData) {
if(fragment is SpecificCurrencyFragment) {
val args = Bundle()
args.putSerializable(SpecificCurrencyFragment.MAP_DATA_RECEIVE, changeFragmentData.mapOfCurrency)
args.putString(SpecificCurrencyFragment.DAY_DATA_RECEIVE, changeFragmentData.day)
fragment.setArguments(args)
}
supportFragmentManager.beginTransaction().apply {
setCustomAnimations(R.anim.fade_in, R.anim.fade_out)
replace(R.id.fragment_container, fragment)
addToBackStack(null)
commit()
}
when (fragment) {
is CurrencyListFragment -> changeToolbarSubtitle("CurrencyListFragment.kt")
is AboutFragment -> changeToolbarSubtitle("AboutFragment.kt")
is SpecificCurrencyFragment -> changeToolbarSubtitle("SpecificCurrencyFragment.kt")
}
}
override fun onBackPressed() {
super.onBackPressed()
finishAffinity()
}
private fun initToolbarMembers() {
//findViewById<TextView>(R.id.toolbar_title).setOnClickListener { changeFragment(CurrencyListFragment(), ChangeFragmentData()) }
findViewById<TextView>(R.id.about).setOnClickListener { changeFragment(AboutFragment(), ChangeFragmentData()) }
toolbarSubtitle = findViewById(R.id.toolbar_subtitle)
}
private fun changeToolbarSubtitle(subtitle: String) {
toolbarSubtitle.text = subtitle
}
}
