当Android Textinput autoFocus为true时，不会弹出本机键盘

Question

When entering the screen the keyboard should open automatically, the problem only happens on Android.

Is there another solution to open the keyboard automatically?

You can use a useRef hook to do this. Live example ( https://snack.expo.dev/@heytony01/smiling-candy ).

export default function App() {
  const textInputRef = React.useRef();

  // Focuses on keyboard once screen starts 
  React.useEffect(()=>{
    textInputRef.current.focus(); // opens keyboard
  },[])

  return (
    <View style={{flex:1,justifyContent:"center",alignItems:"center"}}>
        <TextInput ref={textInputRef} placeholder="Type here" style={{backgroundColor:"lightgray"}}/>
    </View>
  );
}
