I don't use FrameLayout anywhere, but I guess it's something to do with ScrollView being added to the layout. I tried taking out the ScrollView and no errors appear.
Code:
private void createLayout(WaiterApp app, Order order) {
LinearLayout layout = this;
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(0, 585, 0.5f);
params.setMargins(10, 0, 10, 10);
layout.setLayoutParams(params);
layout.setOrientation(VERTICAL);
TextView title = new TextView(app.getApplicationContext());
params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, 125);
title.setBackgroundColor(getResources().getColor(R.color.colorButton, null));
title.setLayoutParams(params);
title.setGravity(Gravity.CENTER);
title.setTextAlignment(TextView.TEXT_ALIGNMENT_TEXT_START);
title.setTextColor(getResources().getColor(R.color.colorTextSecondary, null));
// Format a text
String text;
User servedBy = app.getDB().getUser(order.getWaiterID());
text = "<p> <b>" + getResources().getString(R.string.table_no) + "</b> " + order.getTable().toString() + "<br />"
+ "<b>" + getResources().getString(R.string.waiter_name) + "</b> " + servedBy.getFirstName() + " " + servedBy.getLastName() + "<br />"
+ "<b>" + getResources().getString(R.string.status) + "</b> " + order.getStatus() + "</p>";
// Assign the text
title.setText(Html.fromHtml(text, Html.FROM_HTML_MODE_LEGACY));
layout.addView(title);
// Body
LinearLayout body = new LinearLayout(app.getApplicationContext());
params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, 460);
body.setLayoutParams(params);
body.setBackgroundColor(getResources().getColor(R.color.colorButtonSelected, null));
ScrollView scrollView = new ScrollView(app.getApplicationContext());
params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
scrollView.setLayoutParams(params);
scrollView.setFillViewport(true);
scrollView.setPadding(0, 0, 0, 20);
TextView body_text = new TextView(app.getApplicationContext());
ScrollView.LayoutParams body_params = new ScrollView.LayoutParams(ScrollView.LayoutParams.MATCH_PARENT, ScrollView.LayoutParams.WRAP_CONTENT);
body_params.setMargins(10, 0, 10, 10);
body_text.setLayoutParams(body_params);
body_text.setTextColor(getResources().getColor(R.color.colorTextSecondary, null));
// Format text based on items that belong to the order
StringBuilder sb = new StringBuilder();
ArrayList<OrderItem> items = app.getDB().getOrderItems(order.getID());
for (OrderItem i : items) {
Item item = app.getDB().getItem(i.getItemID());
// First line
sb.append(i.getQuantity());
sb.append("x ");
sb.append(item.getName());
// Second line
if (i.getComment().length() != 0) {
sb.append("\n");
sb.append("(");
sb.append(i.getComment());
sb.append(")");
}
sb.append("\n\n");
}
body_text.setText(sb);
scrollView.addView(body_text);
body.addView(scrollView);
layout.addView(body);
// Remove order button (only shows if order was placed by the same user)
if (order.getWaiterID() == app.getUser().getID()) {
// Make body_text smaller
params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, 400);
params.setMargins(10, 135, 10, 0);
body_text.setLayoutParams(params);
TextView remove_text = new TextView(app.getApplicationContext());
params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, 80);
params.setMargins(0, 505, 0, 0);
remove_text.setLayoutParams(params);
remove_text.setBackgroundColor(getResources().getColor(R.color.colorRed, null));
remove_text.setTextSize(15);
remove_text.setTextColor(getResources().getColor(R.color.colorWhite, null));
remove_text.setGravity(Gravity.CENTER);
remove_text.setText(getResources().getString(R.string.order_remove));
layout.addView(remove_text);
}
}
The layout created by the function is added as a child to another LinearLayout.
If someone could explain what I'm doing wrong I would appreciate it a lot. At the moment I just can't see where I've gone wrong.

Note :- ScrollView parent is FrameLayout. so, LayoutParams use Framelayout
ScrollView scrollView = new ScrollView(this);
FrameLayout.LayoutParams layoutParams= new
FrameLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT,
FrameLayout.LayoutParams.WRAP_CONTENT);
scrollView.setLayoutParams(params);

Fragment Error when moving the same screen

https://github.com/MobileSeoul/2017seoul-18
I brought open source from Github.
But, this code was designed to push only one button at a time.
So, as soon as I started, I changed 4 information to appear on the screen.
#Override
public void onResume() {
super.onResume();
String[] urls = {queryUrlFsn, queryasthmaWho, querybrainWho, queryskinWho};
if (checkInternet() == true) {
INTERNET_STATE = true;
thread(urls[0], date, 0);
new addThread(fsnIndex, "Food Poisoning Index", value[0], FSN_DIVIDE_VALUE, R.drawable.fsn, showDateTime(showDate)).start();
thread(urls[1], date, 1);
new addThread(asthmaWhoIndex, "Asthma lung disease possible index", value[1], WINTERLIFE_DIVIDE_VALUE, R.drawable.asthmawho, showDateTime(showDate)).start();
thread(urls[2], date, 2);
new addThread(brainWhoIndex, "Stroke index", value[2], WINTERLIFE_DIVIDE_VALUE, R.drawable.brainwho, showDateTime(showDate)).start();
thread(urls[3], date, 3);
new addThread(skinWhoIndex, "Skin disease potential index", value[3], WINTERLIFE_DIVIDE_VALUE, R.drawable.skinwho, showDateTime(showDate)).start();
} else {
Toast.makeText(getActivity(),"Network not connected", Toast.LENGTH_SHORT).show();
}
}
https://youtu.be/NuxS6MH55oA
↑ However, when moving from screen A back to screen A, there was a problem that the app was shutting down.
When I checked it, I did not have any problem when I removed the 4 pieces of information displayed on the screen A by clicking on the "trash can picture" and then moved to the screen A again.
So, in order to initialize the screen when I switch the screen, I did googleing.
I put the code presented in the stack overflow in the if / else statement below.
Reset/reload fragment container
#SuppressWarnings("StatementWithEmptyBody")
#Override
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
MosquitoFragment mosquitoFragment = new MosquitoFragment();
WeatherFragment weatherFragment = new WeatherFragment();
ExpressionFragment expressionFragment = new ExpressionFragment();
AirFragment airFragment = new AirFragment();
int id = item.getItemId();
if (id == R.id.nav_weather) {
// I inserted this point.
transaction.replace(R.id.content_frame, weatherFragment);
}
else if (id == R.id.nav_mosquito) {
// I inserted this point.
transaction.replace(R.id.content_frame, mosquitoFragment);
}
else if (id == R.id.nav_expression) {
// I inserted this point.
transaction.replace(R.id.content_frame, expressionFragment);
}
else if (id == R.id.nav_air) {
// I inserted this point.
transaction.replace(R.id.content_frame, airFragment);
}
transaction.commit();
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
However, when I move from A screen to A screen again, an error still occurs. How do we solve it? If I can not solve this problem, I will not fix this open source.

How to fix getCount() in viewPager adapter in Android [duplicate]

This question already has answers here:
What is a NullPointerException, and how do I fix it?
(12 answers)
Closed 5 years ago.
I want use viewPager in my application and I want use this library: UltraViewPager.
I write below codes in adapter:
public class BoxOfficeAdapter extends PagerAdapter {
private Context context;
private List<BoxOfficeDatum> model;
private LayoutInflater inflater;
private BoxOfficeDateListener listener;
public BoxOfficeAdapter(Context context, List<BoxOfficeDatum> model, BoxOfficeDateListener listener) {
this.context = context;
this.model = model;
this.listener = listener;
this.inflater = (LayoutInflater) this.context.getSystemService(this.context.LAYOUT_INFLATER_SERVICE);
}
#Override
public int getCount() {
return model.size();
}
#Override
public Object instantiateItem(final ViewGroup container, final int position) {
View view = this.inflater.inflate(R.layout.row_box_office, container, false);
return view;

How can I fix it?

List is null that why null Pointer is coming .
try different method to set data from response to your list
Like:
BoxOfficeResponse responseBody=response.body();
boxOfficeModel.addAll(responseBody.getBoxOfficeData().getBoxOfficeDatum())
or
for(int i=0; i<responseBody.getBoxOfficeData().getBoxOfficeDatum(); i++){
boxOfficeModel.add(responseBody.getBoxOfficeData().getBoxOfficeDatum().get(i))
}

FragmentManager throws IllegalArgumentException in Kotlin

I have the following method in my Fragment
override fun onActivityCreated(savedInstanceState: Bundle?) {
super.onActivityCreated(savedInstanceState)
val fm = childFragmentManager
var prefsFragment: PrefsFragment? = fm.findFragmentByTag(tableName) as PrefsFragment?
if (prefsFragment == null) {
prefsFragment = PrefsFragment()
val ft = fm.beginTransaction()
ft.add(R.id.parameters_fragment_container, prefsFragment, tableName)
ft.commit()
fm.executePendingTransactions()
}
}
I have to say this is what the Java->Kotlin automagic translator did with my previous Java code (save for the ? at the end of the line where I find the PrefsFragment by tag), so it may not be entirely kosher. I'm learning Kotlin by doing.
Now, when I call executePendingTransactions(), my app crashes throwing java.lang.IllegalArgumentException with error message "Parameter specified as non-null is null: method kotlin.jvm.internal.Intrinsics.checkParameterIsNotNull, parameter savedInstanceState". Now, yes, savedInstanceState is in fact null, but what does it have to do with the call that apparently throws the exception? I made sure that no other values/variables are null, so I'd trust the error message... but why?
EDIT Here is the stack trace, and the source code that's giving me nightmares

The exception isn't actually coming from that code. It is coming from your CalculatorScreen.PrefsFragment.onCreatePreferences() method. If you look there, it looks like --
override fun onCreatePreferences(savedInstanceState: Bundle, rootKey : String)
and it should be the following to allow savedInstanceState to be null --
override fun onCreatePreferences(savedInstanceState: Bundle?, rootKey : String)
