In my code I have 2 EditBox and a Switch. When I click on Switch to true it sets visible linear layout that contains one more EditText with imagelinearLayout.setVisibility(View.VISIBLE);
On the bottom I have a Button that does calculations of 2 cases:
- case when Switch is
android:checked="false", where it just calculates values of first 2 EditBox-s - case when Switch is
trueand I use the third EditBox in caluculation with the first 2 Editbox-s
PROBLEM:
When I open the Activity and enter values in the first 2 EditBox the, and Switchs is defaultly false, I click on the Button to calculate and nothing happens.
But, if I just change state of Switch to true and to false again. Then I click to button and it calculates with no problem.
It completely ignores my code until I change state.

I tried with adding some boolean value in the onCheckedChanged so if it doesn't change state for the first time I could copy the code of calculate.setOnClickListener but it doesn't work.
