click a button to add Linear Layout within another layout
the on click listener is:

optionText.text = optionList[j]
optionView.addView(tempOption)
}
finalQuestion.addView(tempQuestion)
}
}
whenever i click the button my application is crashed.

Caused by: java.lang.IllegalArgumentException: The style on this component requires your app theme to be Theme.AppCompat (or a descendant).
You need to use a theme that is derived from Theme.AppCompat. YOu probably shouldn't be passing in null for the parent view anyway. You're adding it to finalQuestion eventually, just pass finalQuestion in as the parent. That will make it use the theme from finalQuestion, and automatically add it for you.

I am using this library to make calendar app similar to google calendar week view calendar. I read all documentation and added implementation 'com.jonaswanke.calendar:calendar:0.1.1' in build.gradle, but when I add calendar view to activity_mail.xml
<com.jonaswanke.calendar.CalendarView
android:id="#+id/calendar"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:range="week" />

But even without this code app still crashes.
This is an old library that was built using experimental Kotlin features. It hasn't been maintained for two years. I tried for 20 minutes to get it to compile. It's just not worth it. I suggest using one of the several other Android CalendarView libraries out there:
https://github.com/search?q=android+calendarview
This one looks particularly promising:
https://github.com/kizitonwose/CalendarView
I wrote bellow code in fragment that extends 'VideoSupportFragment'
val playerGlue = PlaybackTransportControlGlue(
activity,
MediaPlayerAdapter(activity))
playerGlue.setHost(VideoSupportFragmentGlueHost(this))
playerGlue.addPlayerCallback(object : PlaybackGlue.PlayerCallback() {
override fun onPreparedStateChanged(glue: PlaybackGlue) {
if (glue.isPrepared()) {
//playerGlue.seekProvider = MySeekProvider()
playerGlue.play()
}
}
})
playerGlue.playerAdapter?.setDataSource(Uri.parse("http://techslides.com/demos/sample-videos/small.mp4"))
When setHost is called app crashes and bellow log appears in logcat.
If i comment setHost, just audio get play.

I don't know why the class is unknown.
i can't find which layout has error because of this.
After long time searching i find the reason.
The Activity that contains the Fragment should set theme to Leanback
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setTheme(R.style.Theme_Leanback)
}
I'm following MabBox tutorial at https://docs.mapbox.com/help/tutorials/android-navigation-sdk/ to make a simple navigation fragment that use the basics elements of it.
I already know that MapBox require to instantiate before inflating the View because I made it before on another Fragment to test it out where the fragment is part of a TabLayout component, however, in this one, there's only one Activity that loads the Fragment where I use the SDK and in this case it throws the same error that I fixed previously because I put it afterinflating the layout.
The errore that appears is this one:

The code for the Activity is:
class MapDirectionActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_map_direction)
supportFragmentManager.inTransaction {
add(R.id.form_clientNavMenu, MapDirectionFragment())
}
//Logout action on custom toolbar layout
logout.setOnClickListener {
val intent = Intent(this, MainActivity::class.java)
startActivity(intent)
}
}
}
The code for the onCreateView method of the Fragment is:
override fun onCreateView(
inflater: LayoutInflater, container: ViewGroup?,
savedInstanceState: Bundle?
): View? {
Mapbox.getInstance(context!!, getString(R.string.access_token))
val view = inflater.inflate(R.layout.fragment_map_direction, container, false)
mapView = view.findViewById(R.id.mapView)
mapView.onCreate(savedInstanceState)
mapView.getMapAsync(this)
// Inflate the layout for this fragment
return view
}
I only wrote onCreateView method because I think the error could be in there instead on the rest of the code which is the same as in the link, but I could be wrong.
Set the method:
Mapbox.getInstance(this,getString(R.string.access_token));
Before the:
setContentView(R.layout.activity_map);
If you having this exception change code structure as follows.
i.e:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Mapbox.getInstance(this,getString(R.string.access_token));
setContentView(R.layout.activity_map);
mapView = (MapView) findViewById(R.id.mapView);
mapView.onCreate(savedInstanceState);
mapView.getMapAsync(mapboxMap -> mapboxMap.setStyle(
new Style.Builder().fromUrl(Style.MAPBOX_STREETS)
));
}
Thanks #Tobrun for the answer, the problem was not that I missed the accessToken but I mixed activity and fragment layout so the components in one of them should be in the other. However, looking for the accessToken made me realize about other possible ones.
I want to make an Android project with Kotlin, so I build it with kotlin and Databinding. It's nothing wrong with it. But when I use Kotlin Android Extensions or Butterknife, the app I built from this project can not be used normally.
Here is my fragment class
class MainFragment: Fragment() {
private var stock: StockQuote? = null
override fun onCreateView(inflater: LayoutInflater?, container: ViewGroup?, savedInstanceState: Bundle?): View {
val binding: FragmentMainBinding = DataBindingUtil.inflate(inflater!!, R.layout.fragment_main, container, false)
binding.stock = stock
search_et.setOnFocusChangeListener { v, hasFocus ->
if(!hasFocus){
val newStock = ScrapingUtil.getQuote(search_et?.text.toString())
if(newStock != null){
stock?.name = newStock.name
}
}
}
return binding.root
}
}
I tried to use Butterknife at first but it didn't work, the View I want to bind would be null. Then I tried to use Kotlin Android Extensions, it threw an error at runtime

how can I fix it?
I found the answer at Kotlin Android Extensions and Fragments.
DataBinding doesn't matter, you should directly access search_et in the onViewCreated method
I am using a preference fragment, and I get a exception on my XML. It used to work, but I've tweaked something and now it consistently crashes when I press the 3 dots in the top right hand for the menu.
The actual error is:
java.lang.RuntimeException: Unable to start activity ComponentInfo{org.sherman.android.babynme/org.sherman.android.babynme.Activites.SettingsActivity}: android.view.InflateException: Binary XML file line #0: Binary XML file line #0: Error inflating class fragment
Here is my activity_settings.xml:
<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android='http://schemas.android.com/apk/res/android'
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/activity_settings"
android:name="org.sherman.android.babynme.Fragments.SettingsFragment" />
my preferencesXML:
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<EditTextPreference
android:defaultValue="Name"
android:key="baby_name"
android:title="Baby's Name" />
<EditTextPreference
android:defaultValue="01/01/01"
android:key="baby_dob"
android:title="Baby's Birthday" />
<EditTextPreference
android:numeric="integer"
android:defaultValue="21"
android:key="mum_age"
android:singleLine="true"
android:title="Your age" />
</PreferenceScreen>
My SettingsActivity.kt:
class SettingsActivity : AppCompatActivity(){
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_settings)
val sharedPreferences: SharedPreferences = PreferenceManager.getDefaultSharedPreferences(this)
val babyName:String = sharedPreferences.getString("baby_name", "Baby")
title = babyName+" 'n Me"
val actionBar = this.supportActionBar
if(actionBar != null){
actionBar.setDisplayHomeAsUpEnabled(true)
}
}
override fun onOptionsItemSelected(item: MenuItem?): Boolean {
val id = item?.itemId
if(id == android.R.id.home){
NavUtils.navigateUpFromSameTask(this)
}
return super.onOptionsItemSelected(item)
}
}
And the code for the SettingsFragment:
class SettingsFragment: PreferenceFragmentCompat(), SharedPreferences.OnSharedPreferenceChangeListener {
val mContext = context
override fun onCreatePreferences(savedInstanceState: Bundle?, rootKey: String?) {
addPreferencesFromResource(R.xml.pref_baby)
val sharedPreferences: SharedPreferences = android.preference.PreferenceManager.getDefaultSharedPreferences(activity.applicationContext)
onSharedPreferenceChanged(sharedPreferences, "baby_name")
onSharedPreferenceChanged(sharedPreferences, "baby_dob")
onSharedPreferenceChanged(sharedPreferences, "mum_age")
}
override fun onResume() {
super.onResume()
preferenceScreen.sharedPreferences.registerOnSharedPreferenceChangeListener(this)
//activity.getSharedPreferences(context.packageName, Context.MODE_PRIVATE).registerOnSharedPreferenceChangeListener(this)
}
override fun onPause() {
super.onPause()
preferenceScreen.sharedPreferences.unregisterOnSharedPreferenceChangeListener(this)
//activity.getSharedPreferences(context.packageName,Context.MODE_PRIVATE).unregisterOnSharedPreferenceChangeListener(this)
}
override fun onSharedPreferenceChanged(p0: SharedPreferences?, key: String?) {
Log.d(DEBUG, "Ospc called")
val pref: Preference = findPreference(key)
val etp: EditTextPreference = pref as EditTextPreference
pref.setSummary(etp.text)
}
Here is the full error log:

My Question is what did I change that caused the menu selection to crash now? (Thank You).
The problem is Caused by: java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.String
You must have changed the data types somewhere.
