执行插入语句程序就闪退，我主要是想将链表中的数据插入数据库
public void createDB(View view) {
SQLiteDatabase db = helper.getWritableDatabase();
String sql = "insert into "+Constant.TABLE_NAME+"values('ew','d')";
DBSet.execSQL(db,sql);
db.close();
}
SQLiteDatabase db = helper.getWritableDatabase();
String sql = "insert into "+Constant.TABLE_NAME+"values('ew','d')";
DBSet.execSQL(db,sql);
db.close();
}
void onCreate(SQLiteDatabase db) {
String sql="create table "+Constant.TABLE_NAME+"("+Constant._ID+" varchar(50) primary key,"+Constant.NEME+" varhar(20))";
db.execSQL(sql);//执行sql语句
