When the basictextfield is at bottom of view and is focused, the basictextfield is moving to the center of screen. How can I stop that? If I remove imePadding(), only half of textfield is visible.
#AndroidEntryPoint
class MainActivity : ComponentActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
WindowCompat.setDecorFitsSystemWindows(window, false)
setContent {
var a by remember {
mutableStateOf("")
}
Box(
modifier = Modifier
.fillMaxSize()
.imePadding()
) {
BasicTextField(
value = a, onValueChange = { a = it }, modifier = Modifier.align(
Alignment.BottomCenter
)
)
}
}
}

I have a category item in my recyclerView.
There is a TextView and two ImageView as button (Edit button and Delete button).
When I click edit button I want to change TextView to EditText and editbutton change for agreebutton. When I write new text just update my old one.
I show you what I have and almost everything working but don't update my new text and I know code don't look nice and maybe someone can show me how to do it better :)
class CategoryAdapter(private val categoryList: List<Category>, val listener: ClickListener) : RecyclerView.Adapter<CategoryAdapter.MyViewHolder>() {
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): MyViewHolder {
return MyViewHolder(CategoryItemBinding.inflate(LayoutInflater.from(parent.context), parent, false))
}
override fun onBindViewHolder(holder: MyViewHolder, position: Int) {
holder.binding.categoryName.text = categoryList[position].name
holder.binding.categoryEditIv.setOnClickListener {
holder.binding.categoryName.visibility = View.GONE
holder.binding.categoryEditName.visibility = View.VISIBLE
holder.binding.categoryEditName.setText(categoryList[position].name)
holder.binding.categoryEditIv.visibility = View.GONE
holder.binding.categoryAgreeIv.visibility = View.VISIBLE
}
val editTxt = holder.binding.categoryEditName
holder.binding.categoryAgreeIv.setOnClickListener {
val edit = editTxt.text.toString()
listener.editAgreeClickItem(edit)
holder.binding.categoryName.visibility = View.VISIBLE
holder.binding.categoryEditName.visibility = View.GONE
holder.binding.categoryAgreeIv.visibility = View.GONE
holder.binding.categoryEditIv.visibility = View.VISIBLE
}
holder.binding.categoryDeleteIv.setOnClickListener {
listener.deleteClickItem(categoryList[position])
}
}
override fun getItemCount(): Int {
return categoryList.size
}
class MyViewHolder(val binding: CategoryItemBinding) : RecyclerView.ViewHolder(binding.root)
interface ClickListener {
fun editAgreeClickItem(text: String)
fun deleteClickItem(category: Category)
}
}

private val binding
get() = _binding!!

override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
shoppingListViewModel = ViewModelProvider(requireActivity())[ShoppingListViewModel::class.java]
}
override fun onCreateView(

savedInstanceState: Bundle?

_binding = FragmentMainBinding.inflate(layoutInflater,container,false)
return binding.root
}
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {

Why does navigation composable call twice? If I set a breakpoint on the Text I will get two stops when the app runs. Thank you for your answers.
class MainActivity : ComponentActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContent {
val navController = rememberNavController()
var i: Int = 0
NavHost(navController = navController, startDestination = "s1") {
composable("s1") {
i++
Text("$i")
}
}
}
}
}
In my adapter of a ViewPager I have the position. What I want to do is add 1 to the position by pressing a Button in the activity but I cannot access the position from the activity. How can I do it?
Adapter:
class MyAdapter(var context: Context,private var myList: List<MyModel>) : PagerAdapter() {
override fun getCount(): Int {
return myList.size
}
override fun isViewFromObject(view: View, `object`: Any): Boolean {
return view == `object`
}
override fun destroyItem(container: ViewGroup, position: Int, `object`: Any) {
container.removeView(`object` as View?)
}
override fun instantiateItem(container: ViewGroup, position: Int): Any {
var view: View = LayoutInflater.from(context).inflate(R.layout.layout_item,container,false)
var img: ImageView = view.findViewById(R.id.imgView)
val listPos= myList[position]
container.addView(view)
return view
}
}
Activity:
class MyActivity : AppCompatActivity() {
private var myAdapter: MyAdapter? = null
private val myList = ArrayList<MyModel>()
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.my_activity_layout)
myAdapter = MyAdapter(this,myList)
myViewPager.adapter = myAdapter
myList.add("Name",R.drawable.img1)
myList.add("Name2",R.drawable.img2)
myList.add("Name3",R.drawable.img3)
myButtonPlus.setOnClickListener{
//Here I want to +1 the position for every click
}
myButtonMinus.setOnClickListener{
//Here I want to -1 the position for every click
}
}
}
If you want to increase and decrease your ViewPager position you should use the setCurrentItem function.
Try to change your code like this:
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.my_activity_layout)
myAdapter = MyAdapter(this,myList)
myViewPager.adapter = myAdapter
myList.add("Name",R.drawable.img1)
myList.add("Name2",R.drawable.img2)
myList.add("Name3",R.drawable.img3)
myButtonPlus.setOnClickListener{
//Here I want to +1 the position for every click
val currentPage = myAdapter?.currentItem ?: 0
val maxPage = myAdapter?.childCount ?: 0
if (currentPage < maxPage) {
myAdapter?.currentItem = currentPage + 1
}
}
myButtonMinus.setOnClickListener{
//Here I want to -1 the position for every click
val currentPage = myAdapter?.currentItem ?: 0
if (currentPage > 0) {
myAdapter?.currentItem = currentPage - 1
}
}
}
I'm having a problem with this SmartToolbar, if I open the app and click on the chat or book icon it opens perfectly and shows the fragments, but if I click on another icon to open another fragment, when I go back to them they don't show more The fragments that should be on the smartToolbar, as shown in the prints below, bug everything! I need to help on this as soon as possible !!!
[Opens normally When I click on another item and go back to it, it no longer opens the SmartToolbar fragmentshere]2
enter image description here
I will send the homeAcitivity code, where is the layout that opens the fragments of the buttonNavigationBar
class HomeActivity : AppCompatActivity() {
var MY_ACCOUNT = 1
var LIBRARY = 2
var HOME = 3
var CHAT = 4
var SETTINGS = 5
private var Content: ConstraintLayout? = null
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
supportActionBar!!.hide()
nav.show(HOME)
nav.setBackgroundColor(Color.TRANSPARENT)
abrirHome()
addOnMeowNavigattionBarIcons()
addOnNotificationInform()
chamarFragments()
}
fun abrirHome() {
val fragment = HomeFragment.newInstance()
addFragment(fragment)
}
fun addOnMeowNavigattionBarIcons() {
nav.add(MeowBottomNavigation.Model(MY_ACCOUNT, R.drawable.ic_baseline_account_circle_24))
nav.add(MeowBottomNavigation.Model(LIBRARY, R.drawable.ic_baseline_menu_book_24))
nav.add(MeowBottomNavigation.Model(HOME, R.drawable.ic_baseline_home_24))
nav.add(MeowBottomNavigation.Model(CHAT, R.drawable.ic_baseline_chat_24))
nav.add(MeowBottomNavigation.Model(SETTINGS, R.drawable.ic_baseline_settings_24))
}
fun addOnNotificationInform() {
nav.setCount(CHAT, "99")
}
fun chamarFragments() {
nav.setOnClickMenuListener {
when (it.id) {
HOME -> {
val fragment = HomeFragment.newInstance()
addFragment(fragment)
}
MY_ACCOUNT -> {
val fragment = MyAccountFragment.newInstance()
addFragment(fragment)
}
LIBRARY -> {
val fragment = LibraryFragment.newInstance()
addFragment(fragment)
}
CHAT -> {
val fragment = ChatFragment.newInstance()
addFragment(fragment)
}
SETTINGS -> {
val fragment = SettingsFragment.newInstance()
addFragment(fragment)
}
}
}
}
private fun addFragment(fragment: Fragment) {
supportFragmentManager
.beginTransaction()
.replace(R.id.parentfragments,fragment,fragment.javaClass.simpleName)
.addToBackStack(null)
.commit()
}
fun sair(view: View){
FirebaseAuth.getInstance().signOut()
val bundle = ActivityOptions.makeSceneTransitionAnimation(this).toBundle()
val intent = Intent(this, login::class.java)
startActivity(intent,bundle)
}
}
This is the code of the fragment Library that has a SmartToolbar that calls two more fragments within it, MyLibrary and Store
class LibraryFragment: Fragment() {
companion object{
fun newInstance():LibraryFragment {
val args = Bundle()
val fragment = LibraryFragment()
fragment.arguments = args
return fragment
}
}
override fun onCreateView(
inflater: LayoutInflater,
container: ViewGroup?,
savedInstanceState: Bundle?
): View {
return inflater.inflate(R.layout.library_fragment, container, false)
}
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
val adapter = FragmentPagerItemAdapter(
fragmentManager, FragmentPagerItems.with(context)
.add("Minha Bilioteca", MyLibraryFragment::class.java)
.add("Loja", StoreFragment::class.java)
.create())
viewpager.adapter = adapter
viewpagertab.setViewPager(viewpager)
}
}
And this is the MyLibrary fragment that is shown inside the Library that is shown inside HomeActivity
class MyLibraryFragment: Fragment() {
override fun onCreateView(
inflater: LayoutInflater,
container: ViewGroup?,
savedInstanceState: Bundle?
): View? {
return inflater.inflate(R.layout.mylibrary_fragment, container, false)
}
}
I have a simple increment app. When you press on the button the number goes up. However i also made the number change to red once it's higher then 5.
I was able to get the number to save on rotation however the colour resets back to normal.
I'm not sure how i can also save the colour. Any ideas on how i can do this?
// number starts at 0
var num = 0
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
val textView = findViewById<TextView>(R.id.textView)
val add = findViewById<Button>(R.id.button)
add.setOnClickListener {
++num
if(num > 5) {
textView.setTextColor(Color.parseColor("#FF0000"))
}
textView.setText(num.toString())
}
}
override fun onSaveInstanceState(outState: Bundle) {
super.onSaveInstanceState(outState)
outState.putInt("int", num)
}
override fun onRestoreInstanceState(savedInstanceState: Bundle) {
super.onRestoreInstanceState(savedInstanceState)
if(savedInstanceState != null) {
num = savedInstanceState.getInt("int")
textView.setText(num.toString())
}
}
}
update this method onRestoreInstanceState
override fun onRestoreInstanceState(savedInstanceState: Bundle) {
super.onRestoreInstanceState(savedInstanceState)
if(savedInstanceState != null) {
num = savedInstanceState.getInt("int")
if(num > 5){
textView.setTextColor(Color.parseColor("#FF0000"))
}
textView.setText(num.toString())
}
}
