How to create a view programmatically at 12 AM every day

How would I go about creating a TextView at 12 AM every day, regardless if the app is open or not (unbound to app lifetime)? I already have the code to create the TextView, I just need to know how I would execute the code at 12 AM every day.
I'm not going to be opening another activity, everything will be done within the same activity.
Here is my code and my xml:
package com.example.app1;
import android.app.AlarmManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.content.SharedPreferences;

public class NotesActivity extends AppCompatActivity implements View.OnClickListener {
LinearLayout linearLayout;
ImageButton addNoteButton, infoButton;
TextView titleTextNotes;
ArrayList<TextView> notesList;
SharedPreferences sharedPreferences;
Calendar calendar;
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_notes);
sharedPreferences = this.getSharedPreferences("Notes Preferences", Context.MODE_PRIVATE);
linearLayout = findViewById(R.id.linearLayout);
addNoteButton = findViewById(R.id.addNoteButton);
infoButton = findViewById(R.id.infoButton);
titleTextNotes = findViewById(R.id.titleTextNotes);
notesList = new ArrayList<>();
Bundle extras = getIntent().getExtras();
String noteTitle = extras.getString("noteTitle");
if(notesList.size() == 0) {
notesList.add(getStyledNote(noteTitle));
linearLayout.addView(notesList.get(notesList.size() - 1));
}
/*addNoteButton.setOnClickListener(view -> {
notesList.add(getStyledNote("My Log"));
notesList.get(notesList.size() - 1).setOnClickListener(this);
linearLayout.addView(notesList.get(notesList.size() - 1));
});*/
for(int i = 0; i < notesList.size(); i++) {
notesList.get(i).setOnClickListener(this);
}
titleTextNotes.setOnClickListener(this);
for(int i = 0; i < sharedPreferences.getInt("Number of notes", 0); i++) {
notesList.add(getStyledNote(sharedPreferences.getString("Note " + i, "My Log")));
linearLayout.addView(notesList.get(notesList.size() - 1));
}
infoButton.setOnClickListener(view -> callInfoActivity());
}
#Override
public void onClick(View view) {
SharedPreferences.Editor editor = sharedPreferences.edit();
editor.putInt("Number of notes", notesList.size());

}
}
public void callMainActivity(int pos) {

sendInfoBack.putExtra("noteTitleSentBack", notesList.get(pos).getText());
setResult(RESULT_OK, sendInfoBack);
overridePendingTransition(R.anim.leave, R.anim.enter);
finish();
}
public void callInfoActivity() {
Intent intentToLoad = new Intent(NotesActivity.this, InfoActivity.class);
startActivity(intentToLoad);
overridePendingTransition(R.anim.enter, R.anim.leave);
}
public TextView getStyledNote(String noteTitle) {
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, 175);
params.gravity = Gravity.CENTER;
params.setMargins(0, 10, 0, 10);

You need to schedule a periodic task using Work Manager.
val myUploadWork = PeriodicWorkRequestBuilder<SaveImageToFileWorker>(
24,TimeUnit.HOURS) // The work is scheduled to repeat after 24 hours.
.build()
Then you can submit the request to system :
WorkManager
.getInstance(myContext)
.enqueue(myUploadWork)
You can get more code and help from here.

How to create nested child on firebase android

[Solved. I solved it myself]
Tips: if you want to access a child in the firebase realtime database for collecting data and then by using that data u store or upload something at that child on the firebase realtime database again, then you can't access it. Either u have to create another child or u must not use that child. (I don't no the actual solution but It works for me)]
I want to create a child under the reference of the user phone number. That child will store one or more childs. These child will be called "serialNo" of the item. And under serialNo child, the item name and amount of piece will store. I want to create like this:
[N: B: I've created this on firebase directly, not by my application.]
But when I put my data object as .setValue(dtObject) the previous one will always be replaced.
"orderNo: 1" child was replaced by "orderNo: 2" child
I also use .updateChildren(dtMap) but everytime previous orderNo child was replaced.

do you not just need to repeat the same proccess inside the onCheckChangedListener?
rg.setOnCheckedChangeListener(new OnCheckedChangeListener() {
#Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
//Create another radio group here
//then add it to the view
RadioGroup rg2 = new RadioGroup(this); //create the RadioGroup
rg2.setOrientation(RadioGroup.HORIZONTAL);//or RadioGroup.VERTICAL
rg2.setPadding(dpAsPixels, dpAsPixels, dpAsPixels, dpAsPixels);
final Drawable drawableTop = getResources().getDrawable(R.drawable.document_icon);
for (int i = 0; i < itemTypeArrayList.size(); i++) {
if (itemTypeArrayList.get(i).getActive() == 1) {
rb = new RadioButton(this);
rg2.addView(rb); //the RadioButtons are added to the radioGroup instead of the layout
rb.setText(itemTypeArrayList.get(i).getCode());
rb.setId(itemTypeArrayList.get(i).getId());
}
}
itemDetailsLinearLayout.addView(rg);
}
});
You may need to declare rg2 public at the top of the class so it can be accessed by the onCheckChangedListener

Android error on change layout in same activity

I'm developing an android application. It is an exam app. When a user clicks an answer, the application changes the layout with $setContentView(); in same activity.
But it gives an error for layout Caused by: java.lang.NumberFormatException: unable to parse '#2131230721' as integer
My layout file is below, if you need I can put my project myserver. And I can paste my activity code, but it's a basic setContentView() only. I guess one of my id's is causing the error but i couldn't find it.

Thanks for all help

Thanks too much for your effort Barak , Alex Lockwood and the others too i recode my xml layout upon your advices nothing changed but i could seen an error cant be realize before due to my unnecassary LinearLayout block .Whatever the error is :there is a statement in my layout
android:textStyle="#style/boldText"
in this statement the value can be only bold or normal etc .this statement should be like
style="#style/choiceStyle"
thanks for your help .I decided not to work after 00:00

Are you saying you are trying to use setContentView more than once in an activity?
From everything I have read, that won't work.
If you want to change your UI without switching activities you need to use fragments, or put all of the Views you want into your one layout and hide/show only the relevant ones for each portion of your activity with setVisibility().

The reason why you are getting a NumberFormatException is because #2131230721 is not an integer. Here's what you should do:
Re-do your entire XML layout. I am not kidding... the layout you have posted is an absolute disaster. Sorry if that's mean, but I can't let you go on thinking this is the correct way to make your layouts :).
From what I can tell, you are wrapping every single view in a LinearLayout to achieve some sort of margin/padding effect. This is what the android:margin and android:padding attributes are for. Don't over-complicate things with weird android:layout_weight values, as this will make your app run slower when your layout gets inflated. If you ever find that your XML has more than 3 or 4 LinearLayouts you should take a step back and see if you are missing an easier, more efficient solution. It is frowned upon to have nested LinearLayouts too, as it is expensive to inflate these at runtime and will drain your battery as a result.
Do a Project --> Clean and restart eclipse.
Post more information. For example, your entire logcat output would be nice (not just one line). Posting your code is almost always a good idea too. It is very difficult to understand the problem from the tiny amount of information you have provided. Remember that it is beneficial to you to provide as much information as you can because the more information we have, the more likely it is that we can help answer your question. You should also provide us with line numbers and/or indicate on which lines the errors occur.
Oh yeah, and welcome to StackOverflow... :P

Is it possible that the weights are causing the problems? I've never used weights as decimals before, I thought they had to be real numbers, I mean like 1 or 2 etc. Floor numbers. Just a thought
From what I can see its something to do with a number and a text view, this could either be the text views color, weight, ID or style.
What's in style/boldText and style/rightAnswer?

You layout file does Start with a LinearLayout and defines a xmlns:android="http://schemas.android.com/apk/res/android", but you end up with a closing <ScrollView> Tag? Is there anything missing? Plus, javaCode would be great!
By the way: did u try to "clean" you project in eclipse, using Project->Clean?
This resets the R file and often helps!

How i can fit to all devices. Can anyone help?? Thanks in advance.

There are couple of possibilities:
use different xml files for different sizes of screen -> check here http://developer.android.com/guide/practices/screens_support.html
you may use scrollview -> http://developer.android.com/reference/android/widget/ScrollView.html
or simply make your layout fit to the smallest screen size you like to support and then just have "a little" unused space on the larger screens.
It really depends on what you need. Probably the most compatible and advanced solution would be 1.
BUT be aware of the fact that EVERY change on the screen layout has to be duplicated for each xml file following this route!

create xml for each device separately. follow this
second way:
create a parent LinearLayout and pass it to the following method
public static boolean isTabletPC(Context context) {
Display display = ((WindowManager) context
.getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay();
if (display.getWidth() >= 1200) {
isTabletPC = true;
return isTabletPC;
} else {
isTabletPC = false;
return isTabletPC;
}
}
public static void fixUiDeviceDependencies(
Activity act, LinearLayout llParent) {
if (Utilities.isTabletPC(act)) {
Display display = ((WindowManager) act
.getSystemService(Context.WINDOW_SERVICE))
.getDefaultDisplay();
LayoutParams params = (LayoutParams) llParent
.getLayoutParams();
params.width = display.getWidth() / 2;
llParent.setLayoutParams(params);
}
}
