这里是我使用的:

  // in the main window
  property bool desktop: {
    switch (Qt.platform.os) {
    case "android":
    case "ios":
    case "winphone":
    case "winrt":
      return false
    default: return true
    }
  }
  visibility: desktop ? Window.AutomaticVisibility : Window.Maximized

关于强制横向移动，将以下内容添加到清单->应用程序->活动属性部分中的项目文件夹/android中的AndroidManifest.xml文件(不是构建目录中的文件):

As for forcing landscape orientation, add the following to the AndroidManifest.xml file in your project folder / android (not the one in the build directory) in the manifest -> application -> activity properties section:

android:screenOrientation="landscape"
