React-native textinput input

when I just came into contact with the rn, login page, when two textinput, were switching input, the next first click was to make the keyboard disappear, and I had to click again to enter it normally. It was the same with clicking the login button. The first time I made the keyboard disappear. I don"t know how to solve the problem. I hope you can give me some advice.
