c++builder 获取Android路径，可以直接用命名空间::写代码
包含头文件#include <System.Ioutils.hpp>
Caption= System::Ioutils::TPath::GetDocumentsPath();
"D:\\Users\\Administrator\\Documents"
System::Ioutils::TFile::Exists
得到文件清单,文件列表
ListBox1->Items->AddStrings( System::Ioutils::TDirectory::GetFiles(Edit1->Text));
递归文件清单
TStringDynArray sl;
sl =TDirectory.GetFiles(path, '*.txt', TSearchOption.soAllDirectories);
