当我点击 TouchableWithoutFeedback 时如何专注于文本输入？

Question

我有一个文本输入。在这个文本输入中，我有一个字母“O”作为图标。我希望当我按下“O”字母时可以点击文本输入，我该怎么做？

目前它不起作用，因为我无法将此属性添加到该字母中。我添加了我的文本输入在应用程序中的外观。提前谢谢你。

这是App.js

export default MainScreen;

这是我的文本输入：

您可以使用来自 React 的 useRef 钩子来聚焦任何元素。您只需创建一个新的 Ref，然后将其分配给 <TextInput /> 和 onPress 任何元素，您可以使用 inputRef.current.focus()

聚焦该输入 ref

const MainScreen = ({ navigation }) => {
  const inputRef = useRef();
  const [text, setText] = useState("");
  ...
  ...
<TouchableWithoutFeedback onPress={() => {inputRef.current.focus()}}>
            <Text style={{ marginRight: 25 }}>O</Text>
          </TouchableWithoutFeedback>
          <TextInput style={{ flex: 1 }} placeholder="Search" placeholderTextColor="#B9B9C5" onChangeText={setText} value={text} ref={inputRef}></TextInput>
...

当我点击 TouchableWithoutFeedback 时如何专注于文本输入？

How can I focus on textinput when i click on TouchableWithoutFeedback?
