我正在使用eclipse jsp和mysql开发一个Android应用程序。在这里我需要在正确的标签下显示android布局中特定表的所有行（例如：我在mysql中有一个名为demo的表，其中包含字段ID名称和地址，我希望在android中显示所有的demo表行表格式（id，name，address））。我怎么能用jsp和android做到这一点？有人请帮助我。

使用数组列表和bean类来获取和显示您想要显示的数据

 public ArrayList<SigninBean> getUser() {
            //      onCreate(getWritableDatabase());
            SigninBean sBean = new SigninBean();
            ArrayList<SigninBean> arList = new ArrayList<>();
            // String selectQuery = "SELECT * FROM " + TABLE_Name + " WHERE "
            //         + KEY_DATE + " = ?";
            // String[] args={tag};
            SQLiteDatabase db = this.getReadableDatabase();
            String query = "SELECT * FROM " + TABLE;
            Cursor cursor = db.rawQuery(query, null);


            if (cursor.moveToFirst()) {

                while (cursor.isAfterLast() == false) {

                    String d = cursor.getString(cursor.getColumnIndex(COLUMN_signin_date));
                    String photo = cursor.getString(cursor.getColumnIndex(COLUMN_signin_photo));
                    String gender = cursor.getString(cursor.getColumnIndex(COLUMN_signin_gender));
                    String time = cursor.getString(cursor.getColumnIndex(COLUMN_signin_time));
                    String accurate = cursor.getString(cursor.getColumnIndex(COLUMN_Signin_accurate));
                    String name = cursor.getString(cursor.getColumnIndex(COLUMN_signin_name));
                    String city = cursor.getString(cursor.getColumnIndex(COLUMN_signin_city));
                    String country = cursor.getString(cursor.getColumnIndex(COLUMN_signin_country));

                    sBean.setName(name);
                    sBean.setPhoto(photo);
                    sBean.setTime(time);
                    sBean.setGender(gender);
                    sBean.setCity(city);
                    sBean.setCountry(country);
                    sBean.setDate(d);
                    sBean.setAccurate(accurate);
                    Log.e("User values r=========>", "" + d + " " + name + " " + city + " " + country + " " + d);

                    cursor.moveToNext();
                    arList.add(sBean);
                }
            }
