Android: Showing a toast message when the checkbox is checked for the dynamically created checkboxes

When an ImageButton is clicked a checkBox is created dynamically in my app.
The problem I'm facing is with toast messages not showing or let's say the listener I am using for the checkboxes to show a toast message when the checkbox is checked is working only for the current/latest checkbox that has been created. Not for the checkboxes that had been created previously.
Problem,
I saw that the problem could be with the variable (toDoCheckBox) I am using to save the newly created checkbox instance and every time it's getting overriding dynamically as I create newer checkboxes. So for the previous checkboxes, there is no reference pointing to them in order for the listener to work. (the problem could be this or not, i don't know for sure) Even if this is the problem i don't know how to solve it
What i tried is that,
creating the instance of checkbox on both onCreate as well as the createCheckBox method so that I could assign the listener in both the places.
on the onCreate()
on the createCheckbox()
Only the latest created checkbox works and shows the toast messages
Can someone help me or guide me with the problem,
I want the toast message to show for every checkboxes
i posted only the code that could be of some use
private CheckBox toDoCheckBox;
private EditText defaultEditText;
private List<CheckBox> listCheckBoxes;
private int previousViewId = 0;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
this.defaultEditText = findViewById(R.id.defaultEditText);
toDoCheckBox = new CheckBox(this);
this.listCheckBoxes = new ArrayList<>();
this.checkBoxListener = new View.OnClickListener(){
#Override
public void onClick(View view){
if(toDoCheckBox.isChecked()){
toDoCheckBox.setChecked(true);
Toast.makeText(MainActivity.this,"You did a good work, keep it up!",Toast.LENGTH_SHORT).show();
}
}
};
toDoCheckBox.setOnClickListener(checkBoxListener);
}
public void createCheckBox() {
//CREATING A CHECKBOX
toDoCheckBox = new CheckBox(this);
toDoCheckBox.setText(defaultEditText.getText().toString());
toDoCheckBox.setTextSize(20);
toDoCheckBox.setId(View.generateViewId());
ConstraintLayout.LayoutParams params = (ConstraintLayout.LayoutParams) defaultEditText.getLayoutParams();
ConstraintLayout.LayoutParams newParams = new ConstraintLayout.LayoutParams(
ConstraintLayout.LayoutParams.WRAP_CONTENT,
ConstraintLayout.LayoutParams.WRAP_CONTENT
);
newParams.width = params.width;
newParams.height = params.height;
//Constraints
newParams.startToStart = params.startToStart;
newParams.endToEnd = params.endToEnd;
newParams.topToTop = params.topToTop;
newParams.topToBottom = params.topToBottom;
//Margins
newParams.leftMargin = params.leftMargin;
newParams.topMargin = params.topMargin;
newParams.bottomMargin = params.bottomMargin;
newParams.rightMargin = params.rightMargin;
constraintLayout.addView(toDoCheckBox, -1, newParams);
previousViewId = toDoCheckBox.getId();
defaultEditText.setVisibility(View.INVISIBLE);
createEditText();
toDoCheckBox.setOnClickListener(checkBoxListener);
this.listCheckBoxes.add(toDoCheckBox);
totalCheckBox++;
}

Try to use the local checkbox object instead of the global toDoCheckBox.

Save dynamically created tablelayout on screen rotation

I am working on an app that uses 5 tabs and each tab has a different fragment. In all of these fragments I have from 1 up to 10 dynamically created tablelayouts and each one of them can have as many rows as the user wants. Each row may have up to 16 columns of EditText, Spinner, Checkbox. My problem is that when I rotate my phone I lose all the data inside these tablelayouts. My ViewPagerAdapter that hosts these fragments extends FragmentStatePagerAdapter. I am not losing any data outside the tables. I understand that when I rotate the phone they are recreated but I want to keep my data. I do not want to create a database because when I finish adding data in my app I want to save everything to a .txt file. This is code for one of my tables
table18 = (TableLayout) view.findViewById(R.id.blg_parameter18_table);
TableRow.LayoutParams tlparams18 = new TableRow.LayoutParams(
TableRow.LayoutParams.MATCH_PARENT, TableRow.LayoutParams.WRAP_CONTENT);
//Create header
TableRow table18HeaderRow = new TableRow(view.getContext());
table18HeaderRow.setLayoutParams(tlparams18);

When I complete inserting data they are too many to save and recall them one by one everytime i rotate the phone. Any ideas?

When your orientation changes, Android destroys your current activity and creates a new activity again, so you must manage your state.
You can use onSaveInstanceState to save the state and then get the same it in onCreate, for example:
#Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
outState.putSerializable("MyObject", myObject);
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (savedInstanceState != null) {
final MyDataType myData = savedInstanceState.getString("MyObject"));
// fill your layout...
}
}
You can manage the state of your fragments too, please check here. Fragments can be "retain his instance" please read this or this.
Here another great post.
In some projects where I worked, when the application was not prepared for screen rotation, we had to disable this configuration.
I hope this will be useful for you.

Android will automatically save and restore your tables and the associated text views, but you need to do a couple of things.
Make sure each view you want to save has an id. Only views will an id will be saved. See generateViewId and setId.
Note: In order for the Android system to restore the state of the views in your activity, each view must have a unique ID, supplied by the android:id attribute.
Even with an id set, Android will not by default save the value of a TextView presumably because TextViews tend to be static. You can force a save/restore of a TextView by using freezesText.
android:freezesText
If set, the text view will include its current complete text inside of its frozen icicle in addition to meta-data such as the current cursor position. By default this is disabled; it can be useful when the contents of a text view is not stored in a persistent place such as a content provider. For EditText it is always enabled, regardless of the value of the attribute.
There may be some odds and ends to tend to, but that should be the bulk of the changes needed.

Align layout to the bottom of the screen when using a scroll view and adding programmatically views

I have a form with a bunch of relative layouts, each one representing a group.
These are of two kind. One is the filter area which contains a spinner to choose a filter and an edit box for the input from the user and there can be multiple ones. The other kind has only one instance and contains a button that adds the aforementioned kind. This is aligned with the bottom of the parent which is a relative layout that contains all the others. This is also contained into a scroll view so it scrolls when the number of filter areas make the height bigger than the screen. My problem is that once I add enough filter areas to exceed the height of the screen the button gets moved once out of screen, then when you scroll down and press it again to add another one the button stays there. It's like the relative layout doesn't grow any more.
Is it something I have to set up in the xml?
The original xml is the following:
<ScrollView

When I add the first layout that fills the screen and after I scroll down to find the button.
If I press the add button here nothing changes. I know from the debugger that the new layout was created so I am guessing it's out of the screen.

Create view programmatically with style

i have a problem with my application. Basically what it does, is when i click a button, it creates 3 fields (2 editText and 1 spinner) on a scrollView. The thing works well, the only problem that im having, is related with the style, the activity bgColor is white(as the rest of the app) but, when i create elements programmatically, these elements doesnt have the look of the rest of my app. The editTexts are white with white letters (impossible to read since my bgColor is white as well) and its the same thing with the spinner. What can i do? Here is a snipet of code so you can see what im doing here.
public class AddIngredients extends Activity {
public int Count = 0;
public String[] spinnerArray = {"Gr", "kg", "Cups", "ml", "L", "oz"};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.addingredients);
final TableLayout lm = (TableLayout) findViewById(R.id.TableMain);
TableLayout.LayoutParams params = new TableLayout.LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
Button addMore = (Button)findViewById(R.id.addmore);
addMore.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
TableRow ll = new TableRow(getApplicationContext());
//ll.setOrientation(LinearLayout.HORIZONTAL);
EditText product = new EditText(getApplicationContext());
product.setHint(" Ingredient "+Count +" ");
// Create Button
EditText amount = new EditText(getApplicationContext());
// Give button an ID
amount.setId(Count);
amount.setHint("Quantity");
final Button btn2 = new Button(getApplicationContext());
btn2.setId(Count);
btn2.setText("Remove " + Count);
Spinner spinner = new Spinner(getApplicationContext());
ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>(getApplicationContext(), android.R.layout.simple_spinner_dropdown_item, spinnerArray);
spinner.setAdapter(spinnerArrayAdapter);
ll.addView(product);
ll.addView(amount);
ll.addView(spinner);
lm.addView(ll);
Count = Count + 1;
I know my XML is working well because if i create the 3 views on my xml, they look great. PD: Thx in advance for any help! Greetings.

you can use
amount.setTextColor(Color.BLACK);
to set colour of text to black or any other colour
same can be used for spinner

Here's how I set the colors of my edit text lines and other theme-related android views.
http://android-holo-colors.com/
I just picked the color and views I wanted, then unzipped them in my res folder, then set the theme according the android tutorials.
I recommend backing up your res folder first, in case you don't like the results.

I had a error in my code. When creating the fields, i was using
(getApplicationContext());. I fixed it using MyApplicationName.this.

Android, SpannableString, ArrayAdapter and Listview

i am newbie to android and i got a question for you. I want to add icon to a text in a listview. I'm adding the rows(textview) to listview dynamically with below code. But the text doesnt contain the icon.
.
.
.
btnicon = (Button)findViewById(R.id.button1);
txt = (TextView)findViewById(R.id.textView1);
txt.setText(" denemedene",BufferType.SPANNABLE);
list = (ListView)findViewById(R.id.listview);
dizi = new ArrayAdapter<String>(this, R.layout.text);
list.setAdapter(dizi);
btnicon.setOnClickListener(click);
.
.
.
private OnClickListener click = new OnClickListener() {
#Override
public void onClick(View v) {
if (v == btnicon){
SpannableString spans = new SpannableString(txt.getText());
Drawable dra = getResources().getDrawable(R.drawable.p1);
dra.setBounds(0, 0, dra.getIntrinsicWidth() , dra.getIntrinsicHeight());
ImageSpan span = new ImageSpan(dra,ImageSpan.ALIGN_BASELINE);
spans.setSpan(span, 0, 1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
dizi.add(spans.toString());
}
}
};
it is something about the toString method. Because when i change the
dizi.add(spans.toString());
line with
txt.setText(spans,BufferType.SPANNABLE);
it works, i can see the icon on text. I have no idea why it is not working with toString() method.
Any ideas?
Thanks..

There is an example for custom list adapter in this post: https://stackoverflow.com/a/15272092/1752867
You can create your custom adapter like that and change checkbox component with imageView or ProgressBar in the layout
