我试图获取最新的android源码(5.0,只是为了看看它看起来如何),但是当我尝试从Android SDK下载源时,它给了我一个错误,说没有找到本地 URL.这是日志:

我有一个react-native-paper TextInput，当我导航到屏幕时（使用react-native-navigation），我想自动聚焦它。我尝试过autoFocus={true}在 TextInput 上进行设置，但没有成功。

在另一次尝试中，我尝试通过监听屏幕上的“焦点”事件来手动聚焦它，但这仅在我第一次打开屏幕时聚焦。有什么办法让它可靠地工作吗？

export default function NewAccountScreen({ navigation }) {
  const [name, setName] = useState('');

  const textInputRef = createRef();

  // This isn't working, neither is autoFocus...
  const focusOnInput = () => {
    textInputRef.current?.focus();
  }

  navigation.addListener("focus", focusOnInput);

  return (
    <View>
      <TextInput ref={textInputRef} label="Account name" value={name} onChangeText={setName}/>
    </View>
  )
}
