SQliteDatabase 中sql语句引用字符串时的注意点，要把单引号放进去，E/SQLiteLog﹕ (1) no such column:

android.database.sqlite.SQLiteException: no such column: longman (code 1): , while compiling: insert into demo (name,age) values(longman,55)

public void insertData(String name, int age) {
      db.execSQL("insert into demo (name,age) values("+name+","+age+")");
}

修改方法，把单引号放到双引号里面去，也就是当name变成你传入的值的时候，sql语句对string类型的变量就能有双引号功能了：如图绿色所示

public void insertData(String name, int age) {
      db.execSQL("insert into demo (name,age) values(‘"+name+"‘,"+age+")");
}
