How to make all EditText uneditable (and vicer-versa)?

I have an app where there are several text fields. I want to be able to toggle between editing them and not editing them. How can this be done without hard-coding the id for each and everyone one of the EditText?

EditText

For example, I'd like an alternative to

EditText Et = findViewById((R.id.one));
Et.setFocusable(false);
Et.setClickable(false);
Et = findViewById((R.id.two));
Et.setFocusable(false);
Et.setClickable(false);
//...continue the pattern
Et = findViewById((R.id.ten));

Put them in an array:

EditText etArray = findViewById(R.id.one), findViewById(R.id.two), findViewById(R.id.three) ;

for (EditText et : etArray)
et.setFocusable(false);
et.setClickable(false);



or if the names are like EditText1, EditText2,.. for 10 views:

for (int i = 1; i <= 10; i++)
int id = getResources().getIdentifier("EditText" + i, "id", getPackageName());
EditText et = findViewById(id);
et.setFocusable(false);
et.setClickable(false);



or even better, create an ArrayList in onCreate() and use the list:

this declaration goes global in your activity

onCreate()

ArrayList<EditText> etArrayList;


this is for onCreate():

etArrayList = new ArrayList<EditText>();
for (int i = 1; i <= 10; i++)
int id = getResources().getIdentifier("EditText" + i, "id", getPackageName());
EditText et = findViewById(id);
etArrayList.add(et);



and use this anywhere in your activity class:

for (EditText et : etArrayList)
et.setFocusable(false);
et.setClickable(false);



Yes, it is possible to modify your EditTexts without hardcoding stuff. Suppose they're included in a LinearLayout named main_content, then you can loop through each of them in the following way:

LinearLayout

main_content

LinearLayout layout = findViewById(R.id.main_content);
for (int i = 0; i < layout.getChildCount(); i++)
View widget = layout.getChildAt(i);
if (widget instanceof EditText)
widget.setFocusable(false);
widget.setClickable(false);




if

EditText

TableRow

TableRow layout = findViewById(R.id.tableRowID);

EditText

TableRow
