White screen in my activity_main while others not

White screen in my activity_main while others not - android

Hi I am trying to launch an activity which has a navigation drawer and it is simply a Constraintlayout with 4 buttons. But it shows a white screen. My other activities appear perfectly. I don't really know why this happened. It happened before when I was trying to build a gridlayout but now it's just a plain constraintlayout and it still appears the same. If you have any idea, thank you so much!
Here is the XML of a normal layout that works perfectly:

I had just created by mistake a v21 layout file for my activity. This one didn't had any xml code inside. And as my phone is higher than API 21 therefore i always got a white screen. I just deleted the file and it worked out.

Scroll to top of RecyclerView using setOnClickListener

I have this home button in top bar:
val activity: ImageButton =findViewById(R.id.activity)
activity.setOnClickListener{
startActivity(Intent(this, ActivitySearch::class.java))
}
Instead of going to a new page, I want to be able to just put a "to top" intent, I have tried to replace:
startActivity(Intent(this, ActivitySearch::class.java))
with
mRecyclerView.smoothScrollToPosition(0);
But this does not work, any ideas? I do have a RecyclerView in use so half way down, I want to be able to click the above button and it goes straight to the top.
Total code:
private val apiService by lazy {
ApiClient.create()
}
private var taskData : ArrayList<TaskResponse> = arrayListOf();
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
val activity: ImageButton =findViewById(R.id.activity)
activity.setOnClickListener{
startActivity(Intent(this, ActivitySearch::class.java))
}
val searchbutton:ImageButton=findViewById(R.id.searchbutton)
searchbutton.setOnClickListener{
startActivity(Intent(this, ActivitySearch::class.java))
}
val saves:ImageButton=findViewById(R.id.saves)
saves.setOnClickListener{
startActivity(Intent(this, ActivitySaves::class.java))
}
val settings:ImageButton=findViewById(R.id.settings)
settings.setOnClickListener{
startActivity(Intent(this, ActivitySettings::class.java))
}
loadData();
}
private fun loadData(){
var data = apiService.getMainData();
data.enqueue(object : Callback<ArrayList<TaskResponse>> {
override fun onResponse(
call: Call<ArrayList<TaskResponse>>,
response: Response<ArrayList<TaskResponse>>
) {
if (response.code() == 200) {
taskData = response.body()!!;
displaydata();
}
}
override fun onFailure(call: Call<ArrayList<TaskResponse>>, t: Throwable) {
Log.d("-----------------", t.toString())
}
})
}
private fun displaydata(){
var recyclerView = findViewById<RecyclerView>(R.id.mainList);
var adapter = TaskAdapter(this, taskData);
recyclerView.layoutManager = LinearLayoutManager(this)
recyclerView.adapter = adapter
val swipeRefreshLayout: SwipeRefreshLayout = findViewById(R.id.swipeRefreshLayout)
// load data on swipe refresh.
swipeRefreshLayout.setOnRefreshListener { loadData() }
// Disable the refreshing after data load
swipeRefreshLayout.isRefreshing = false
}

This should work for going to the top of the recyclerView.
mRecyclerView.smoothScrollToPosition(0);
or
mRecyclerView.scrollToPosition(0);
When your list changes in recyclerView adapter, you should use that code. Make sure other parts of the code. This should work.

Using a comments answer from #cactustictacs, I edited my code to this and it worked:
val activity: ImageButton =findViewById(R.id.activity)
val mRecyclerView = findViewById<RecyclerView>(R.id.mainList)
activity.setOnClickListener{
mRecyclerView.smoothScrollToPosition(0)
}

ActionBarDrawerToggle stops working on fragment change

I have a HomeActivity which initiates the ActionBarDrawerToggle as follows:
private fun initDrawer() {
val toolbar = binding.fragmentHomeContainerView.findViewById<MaterialToolbar>(R.id.toolbar)
setSupportActionBar(toolbar)
drawerToggle = ActionBarDrawerToggle(
this,
binding.drawer,
toolbar,
R.string.open_drawer,
R.string.close_drawer
)
binding.drawer.addDrawerListener(drawerToggle)
drawerToggle.syncState()
supportActionBar?.setDisplayHomeAsUpEnabled(true)
binding.navigationView.setNavigationItemSelectedListener {
handleNavigationItemSelected(it)
true
}
}
The toolbar in question is inside a Fragment. Everything's normal and working until here, the toolbar is like Gmail's search with the hamburguer icon. But when I navigate to another fragment (that doesn't have this toolbar, but instead has an arrow back button), and then navigate back again to the first fragment (the one that has the toolbar) the icon doesn't work anymore. What's the best/correct solution for this? I've tried moving the initDrawer() function within the fragment but the application frozes when creating the ActionBarDrawerToggle I assume because of the activity passed to the ActionBarDrawerToggle
drawerToggle = ActionBarDrawerToggle(
activity = (requireActivity() as HomeActivity),
...
)
Moving the toolbar from the Fragment to the Activity isn't a solution neither, not because it doesn't fix the problem (which I'm not sure) but because I need the toolbar inside the fragment.
Minimal reproducible code:
MainActivity.kt:
class MainActivity : AppCompatActivity() {
private val binding: ActivityMainBinding by lazy {
ActivityMainBinding.inflate(layoutInflater)
}
private lateinit var drawerToggle: ActionBarDrawerToggle
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(binding.root)
}
override fun onStart() {
super.onStart()
initDrawer()
}
private fun initDrawer() {
val toolbar = binding.fragmentContainerView.findViewById<MaterialToolbar>(R.id.toolbar)
setSupportActionBar(toolbar)
drawerToggle = ActionBarDrawerToggle(
this,
binding.drawer,
toolbar,
R.string.app_name,
R.string.app_name
)
binding.drawer.addDrawerListener(drawerToggle)
drawerToggle.syncState()
supportActionBar?.setDisplayHomeAsUpEnabled(true)
}
}

Android drawer layout header - cannot access it

In my past project from the beggining of the year I have set the content of my drawerHeader in the mainActivity code. I am rewriting it and now it seems impossible to access the header through binding in MainActivity.
I have a usual drawer layout in the activity -> navigation view -> drawer header.
I used to access it through simple binding.layoutDrawer.userDataHeader but it doesn't find userDataHeader no matter what I do. What am I doing wrong?

Recyclerview design issue

First remove code for customizing width and height of recycler item view inside Adapter.
Like:
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): OrdersAdapter.OrderViewHolder {
val itemView = LayoutInflater.from(parent.context).inflate(
R.layout.order_item,
parent,
false
)
//fixing width issue
/*val outMetrics = DisplayMetrics()
val display = parent.display
display?.getRealMetrics(outMetrics)
itemView.layoutParams = RecyclerView.LayoutParams(outMetrics.widthPixels, RecyclerView.LayoutParams.MATCH_PARENT)*/
return OrdersAdapter.OrderViewHolder(itemView)
}
Second, you are not putting any constraint to FragmentContainerView thats why it goes to (0,0) position by default and you have set it's height to wrap_content, so your recycler view looks like the posted image. And it is not recommended to use recycler view inside scroll view. Try with customizing Activity_main.xml as below:
<androidx.constraintlayout.widget.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent">
<com.google.android.material.bottomappbar.BottomAppBar
android:id="#+id/bottomAppBar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
app:fabAlignmentMode="end"
app:fabCradleMargin="10dp"
app:fabCradleRoundedCornerRadius="20dp"
app:fabCradleVerticalOffset="14dp"
app:hideOnScroll="true"
app:menu="#menu/bottom_menu"
tools:ignore="BottomAppBar,MissingConstraints"
app:layout_constraintBottom_toBottomOf="parent"/>
<fragment

android:layout_width="match_parent"
android:layout_height="0dp"
app:defaultNavHost="true"
app:layout_constraintBottom_toTopOf="#+id/bottomAppBar"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent"

<!-- put FAB here -->

How to Make Static Navigation Android Tablet? like this design

Hi I'm having trouble on making layout like this design because the navigation bar is difficult to make it become functional.
this is the design
I have created the class like this:
class MainActivity : AppCompatActivity() {
lateinit var navigationView: NavigationView
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
navigationView = findViewById(R.id.navigation)
navigationView.setNavigationItemSelectedListener(mOnNavigationItemSelectedListener)
}
private val mOnNavigationItemSelectedListener =
BottomNavigationView.OnNavigationItemSelectedListener { item ->
when (item.itemId) {
R.id.navigation_user -> {
val fragment = UserFragment()
addFragment(fragment)
return#OnNavigationItemSelectedListener true
}
R.id.navigation_scaner -> {
val fragment = ScannerFragment()
addFragment(fragment)
return#OnNavigationItemSelectedListener true
}
R.id.navigation_laporan -> {
val fragment = LaporanFragment()
addFragment(fragment)
return#OnNavigationItemSelectedListener true
}
R.id.navigation_notif ->{
val fragment = NotificationFragment()
addFragment(fragment)
return#OnNavigationItemSelectedListener true
}
R.id.navigation_chat -> {
val fragment = LaporanFragment()
addFragment(fragment)
return#OnNavigationItemSelectedListener true
}
R.id.navigation_profile -> {
val fragment = LaporanFragment()
addFragment(fragment)
return#OnNavigationItemSelectedListener true
}
}
false
}
private fun addFragment(fragment: Fragment) = supportFragmentManager
.beginTransaction()
.setCustomAnimations(R.anim.design_bottom_sheet_slide_in, R.anim.design_bottom_sheet_slide_out)
.replace(R.id.content, fragment, fragment.javaClass.simpleName)

I have tried several navigation listener such as navigationView.setNavigationItemSelectedListener(mOnNavigationItemSelectedListener)
But it won't work. Maybe someone know how I can solve my problem? Thanks in advance
