You didn't yet say what specifically the issue is, right?

tame basin
#

this is my MainActivity.java code

why do you have 20 lists? Can't you use a Map?

stiff bone

#

but still - what exactly is the issue?

#

What happens? What do you expect to happen? How is that different?

tame basin
stiff bone
#

oh no

#

I don't think that's a good idea when I'm on my mobile

tame basin
#

it opens in your browser

stiff bone
#

so what's the issue?

stiff bone
tame basin
#

my program for some for some reason doesn't save my checkboxes and progress bars when I go to a different category then go back

stiff bone
tame basin
#

oh

stiff bone

`@Override
public void onSaveInstanceState(@NonNull Bundle outState) {
super.onSaveInstanceState(outState);

    ProgressBar progressBar = findViewById(R.id.progressBar);
    CheckBox checkBox1 = findViewById(R.id.checkBox1);
    CheckBox checkBox2 = findViewById(R.id.checkBox2);
    CheckBox checkBox3 = findViewById(R.id.checkBox3);
    CheckBox checkBox4 = findViewById(R.id.checkBox4);

    outState.putInt("progressBarValue", progressBar.getProgress());
    outState.putBoolean("checkBox1Value", checkBox1.isChecked());
    outState.putBoolean("checkBox2Value", checkBox2.isChecked());
    outState.putBoolean("checkBox3Value", checkBox3.isChecked());
    outState.putBoolean("checkBox4Value", checkBox4.isChecked());
}`
#

do you mean this?

stiff bone
#

But are you also loading it?

stiff bone
tame basin
#

I load it here

#

if (savedInstanceState != null) { progressBar.setProgress(savedInstanceState.getInt("progressBarValue")); checkBox1.setChecked(savedInstanceState.getBoolean("checkBox1Value")); checkBox2.setChecked(savedInstanceState.getBoolean("checkBox2Value")); checkBox3.setChecked(savedInstanceState.getBoolean("checkBox3Value")); checkBox4.setChecked(savedInstanceState.getBoolean("checkBox4Value")); }

.

stiff bone
#

Is that code executed?

tame basin
#

All I want it to do is just load it when I go back into that category

stiff bone
#

also maybe you need to override onResume or similar

tame basin
#

Ok, thanks I will try that

stiff bone
#

onRestoreInstanceState

#

maybe that works

tame basin
#

Oh ok

#

I'm not currently working on it right now because I have to leave for school in a little bit but after 3 o'clock after I get done with work I will be working on it

stiff bone
#

feel free to do it whenever you have time

tame basin
#

Ok, thanks for the help so far

tame basin
#

@stiff bone have you used onRestoreInstanceState or onResume before and did it work in your project?

stiff bone
#

I don't do much with Android development

tame basin
#

Oh, so you haven't used Android Studio before?

stiff bone
#

I did use it a few times

tame basin
#

Sorry, I was just wondering if you were familiar with Android Studio

#

Just curious

I'm back

tame basin
#

@stiff bone how do I get rid of these errors '@layout/activity_main does not contain a declaration with id'

stiff bone
#

I think you can edit the xml and add a plus sign at the beginning of the id

tame basin
#

android:id="@+id/mainActivity"

stiff bone
#

yes

tame basin
#

i have this already

stiff bone
#

where are you getting the error?

where is the layout yml file?

#

xml*

#

and what is it called?

tame basin
#

activity_main.xml

#

what do you mean where?

#

@stiff bone

stiff bone
#

where is the file stored?

#

ig it's something with res

tame basin
#

res\layout

stiff bone
#

can you click alt+enter on the error? What happens?

tame basin
#

suppress MissingInflatedId with an annotation

#

but the 'android:id="@+id/progressBar"' and the checkBoxes 1, 2, 3, 4 are in list_item.xml

tame basin
#

oh I needed to use this 'setContentView(R.layout.list_item);'
