In my activity, I want to take voice input when we click imageView and convert into text and display it in textfield and after we press button it converts it into french(currently it is fixed) and display it in textfield2. I am using yandex translator.
My error:: When I click button for the first time nothing happens in textfield2 but in log, it display the correct translation.After my 2nd click,it changes the textfield2. But i want to show the translation after 1st click only.Why it is taking 2 click for working while my output is coming correct after 2nd click??
