I don't know why my back arrow on the toolbar does nothing, can anybody help me?
I leave here the onCreate of the activity, the adapter and the xml Im using recyclerView with constraint layout
here is the code of the Activity "onCreate" class:
@Override
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(com.owncloud.android.R.layout.accounts_layout)
tintedCheck = ContextCompat.getDrawable(this, com.owncloud.android.R.drawable.ic_current_white)!!
tintedCheck = DrawableCompat.wrap(tintedCheck)
val tint = ContextCompat.getColor(this, com.owncloud.android.R.color.actionbar_start_color)
DrawableCompat.setTint(tintedCheck, tint)
val recyclerView: RecyclerView = findViewById(com.owncloud.android.R.id.account_list_recycler_view)
recyclerView.run {
filterTouchesWhenObscured = PreferenceUtils.shouldDisallowTouchesWithOtherVisibleWindows(applicationContext)
adapter = accountListAdapter
layoutManager = LinearLayoutManager(this@AccountManagementActivity)
}
setupStandardToolbar(
getString(com.owncloud.android.R.string.prefs_manage_accounts),
displayHomeAsUpEnabled = true,
homeButtonEnabled = true,
displayShowTitleEnabled = true
)
val accountList = AccountManager.get(this).getAccountsByType(accountType)
originalAccounts = toAccountNameSet(accountList)
originalCurrentAccount = AccountUtils.getCurrentOwnCloudAccount(this).name
accountListAdapter.submitAccountList(accountList = getAccountListItems())
account = AccountUtils.getCurrentOwnCloudAccount(this)
onAccountSet(false)
/**
// added click listener to switch account
recyclerView.onItemClickListener = OnItemClickListener { parent, view, position, id ->
switchAccount(
position
)
}
*/
}
The code from the Adapter, implementing the recyclerView:
class AccountManagementAdapter(private val accountListener: AccountManagementActivity) : RecyclerView.Adapter<RecyclerView.ViewHolder>() {
private var accountItemsList = listOf<AccountRecyclerItem>()
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): RecyclerView.ViewHolder {
val inflater = LayoutInflater.from(parent.context)
return if (viewType == AccountManagementRecyclerItemViewType.ITEM_VIEW_ACCOUNT.ordinal) {
val view = inflater.inflate(R.layout.account_item, parent, false)
view.filterTouchesWhenObscured = PreferenceUtils.shouldDisallowTouchesWithOtherVisibleWindows(parent.context)
AccountManagementViewHolder(view)
} else {
val view = inflater.inflate(R.layout.account_action, parent, false)
view.filterTouchesWhenObscured = PreferenceUtils.shouldDisallowTouchesWithOtherVisibleWindows(parent.context)
NewAccountViewHolder(view)
}
}
fun submitAccountList(accountList: List<AccountRecyclerItem>) {
accountItemsList = accountList
notifyDataSetChanged()
}
override fun onBindViewHolder(holder: RecyclerView.ViewHolder, position: Int) {
when (holder) {
is AccountManagementViewHolder -> {
val accountItem = getItem(position) as AccountRecyclerItem.AccountItem
val account: Account = accountItem.account
try {
val oca = OwnCloudAccount(account, holder.itemView.context)
holder.binding.name.text = oca.displayName
} catch (e: Exception) {
Timber.w(
"Account not found right after being read :\\ ; using account name instead of display "
"name"
)
holder.binding.name.text = AccountUtils.getUsernameOfAccount(account.name)
}
holder.binding.name.tag = account.name
holder.binding.account.text = DisplayUtils.convertIdn(account.name, false)
try {
val avatarUtils = AvatarUtils()
avatarUtils.loadAvatarForAccount(
holder.binding.icon,
account,
true,
20f
)
} catch (e: java.lang.Exception) {
Timber.e(e, "Error calculating RGB value for account list item.")
// use user icon as a fallback
holder.binding.icon.setImageResource(R.drawable.ic_user)
}
if (AccountUtils.getCurrentOwnCloudAccount(holder.itemView.context).name == account.name) {
holder.binding.ticker.visibility = View.VISIBLE
} else {
holder.binding.ticker.visibility = View.INVISIBLE
}
/// bind listener to refresh account
holder.binding.refreshAccountButton.apply {
setImageResource(R.drawable.ic_action_refresh)
setOnClickListener { accountListener.refreshAccount(account) }
}
/// bind listener to change password
holder.binding.passwordButton.apply {
setImageResource(R.drawable.ic_baseline_lock_reset_grey)
setOnClickListener { accountListener.changePasswordOfAccount(account) }
}
/// bind listener to remove account
holder.binding.removeButton.apply {
setImageResource(R.drawable.ic_action_delete_grey)
setOnClickListener { accountListener.removeAccount(account) }
}
///bind listener to switchAccount
holder.binding.account.apply {
setOnClickListener { accountListener.switchAccount(position) }
}
}
is NewAccountViewHolder -> {
holder.binding.icon.setImageResource(R.drawable.ic_account_plus)
holder.binding.name.setText(R.string.prefs_add_account)
// bind action listener
holder.binding.linearLayout.setOnClickListener {
accountListener.createAccount()
}
}
}
}
override fun getItemCount(): Int = accountItemsList.size
fun getItem(position: Int) = accountItemsList[position]
sealed class AccountRecyclerItem {
data class AccountItem(val account: Account) : AccountRecyclerItem()
object NewAccount : AccountRecyclerItem()
}
class AccountManagementViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
val binding = AccountItemBinding.bind(itemView)
}
class NewAccountViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
val binding = AccountActionBinding.bind(itemView)
}
override fun getItemViewType(position: Int): Int {
return when (getItem(position)) {
is AccountRecyclerItem.AccountItem -> AccountManagementRecyclerItemViewType.ITEM_VIEW_ACCOUNT.ordinal
is AccountRecyclerItem.NewAccount -> AccountManagementRecyclerItemViewType.ITEM_VIEW_ADD.ordinal
}
}
enum class AccountManagementRecyclerItemViewType {
ITEM_VIEW_ACCOUNT, ITEM_VIEW_ADD
}
/**
* Listener interface for Activities using the [AccountListAdapter]
*/
interface AccountAdapterListener {
fun removeAccount(account: Account)
fun changePasswordOfAccount(account: Account)
fun refreshAccount(account: Account)
fun createAccount()
fun switchAccount(position: Int)
}
}
and finally i leave you two xml files, which are the one where all the items are declared and the one where the recyclerView is implemented:

if any more code is needed i can add it :)
i tried adding something like this:
if(item.getItemId() ==android.R.id.home){
onBackPressed();
}
and something like this:
binding.toolbar.setNavigationOnClickListener { navController.popBackStack() }
but nothing worked
CodePudding user response：
Add below code where you define your navController :
override fun onSupportNavigateUp(): Boolean {
return NavigationUI.navigateUp(yourNavController, null) || super.onSupportNavigateUp()
}
CodePudding user response：
I just solved it adding this function at the activity class:
override fun onOptionsItemSelected(item: MenuItem): Boolean {
var retval = true
when (item.itemId) {
R.id.home -> onBackPressed()
else -> retval = super.onOptionsItemSelected(item)
}
return retval
}
