React Native：另一組件頂部的組件

Question

我正在使用react-native-maps和react-native-google-places-autocomplete構建基於位置的iOS應用程序。

在我的代碼中，我先搜索條形碼，然後是地圖代碼，這是因爲搜索欄在地圖上呈現。問題是，我無法移動地圖，因爲搜索欄組件似乎具有佔據整個屏幕的透明元素。當搜索欄被刪除時，我可以移動地圖。我如何在地圖頂部找到搜索欄並移動地圖。

我歡迎替代/更好的方式做我想做的事情。

添加位置樣式的react-native-google-places-autocomplete樣式屬性：

styles={{ 
      container:{ 
      position: 'absolute', 
      top: 0 
      }, 
      description: { 
       fontWeight: 'bold', 
      }, 
      .....
