在SDcard上创建sqlite数据库
public SQLiteDatabase createOrOpenDatabase(String dbName){
?????? //得到SDcard路径
??? ??? String sdPath = Environment.getExternalStorageDirectory().getPath();
??? ??? //System.out.println(sdPath);
??? ??? String dbPath = sdPath + dbName;
?????? //创建一个文件
??? ??? File f = new File(dbPath);
??? ??? try {
??? ??? ??? f.createNewFile();
??? ??? } catch (IOException e) {
??? ??? ??? e.printStackTrace();
??? ??? }
????? //创建数据库
??? ??? sdb=SQLiteDatabase.openOrCreateDatabase(f, null);
??? ??? System.out.println("create successfully");
??? ??? return sdb;
??? }
?
在操作中注意要加上SDcard的读写权限
