android 将数据转换成JSON数据格式并使用JSONObject解析JSON格式的数据

比起XML文件解析，JSON数据解析的有点在于他的体积小，在网络上传输的时候可以更省流量。同时它也有缺点，Json数据的语义性较差，看起来没有XML直观。现在JSON已经被大多数开发人员所接受，在网络数据的传输当中应用非常广泛。现在做的项目需要把数据转换成下面的格式：

 {"PatitentData":[{"patient_mhistory":"高血压","patient_insomnia":"六个月","patient_gender":"男","patient_name":"张三","current_date":"2015.4.10","patient_phone":"1243543546","patient_scde":"大学本科","patient_age":"56","patient_postion":"农民"}],"sleepDiary":[{"day07":"1243535","day06":"12324343","day05":"1243434","day04":"2435434521","day01":"121422343","day02":"1231421454","day03":"1243243"}],"testData":[{"isi":"12324324","hama":"122543543","hamd":"2334255","sleepness":"1243345432","pqsi":"124332144452"}]}

首先建立 PatientInformation.java、PatientTest.java和SleepDiary这三个类，主要是用来封装一些信息

PatientInformation.java

package com.zghaikun.json;public class PatientInformation {private int id;private String patient_name;private String patient_gender;private String patient_age;private String patient_postion;private String patient_scde;private String patient_insomnia;private String patient_mhistory;private String patient_phone;private String current_date;private int patient_hamd;public PatientInformation() {super();}public PatientInformation(int patient_hamd) {super();this.patient_hamd = patient_hamd;}public PatientInformation( String current_date,String patient_name, String patient_gender,String patient_age, String patient_postion, String patient_scde,String patient_insomnia, String patient_mhistory,String patient_phone) {super();this.current_date = current_date;this.patient_name = patient_name;this.patient_gender = patient_gender;this.patient_age = patient_age;this.patient_postion = patient_postion;this.patient_scde = patient_scde;this.patient_insomnia = patient_insomnia;this.patient_mhistory = patient_mhistory;this.patient_phone = patient_phone;}public PatientInformation(int id, String current_date,String patient_name, String patient_gender,String patient_age, String patient_postion, String patient_scde,String patient_insomnia, String patient_mhistory,String patient_phone) {super();this.id = id;this.current_date = current_date;this.patient_name = patient_name;this.patient_gender = patient_gender;this.patient_age = patient_age;this.patient_postion = patient_postion;this.patient_scde = patient_scde;this.patient_insomnia = patient_insomnia;this.patient_mhistory = patient_mhistory;this.patient_phone = patient_phone;}public int getPatient_hamd() {return patient_hamd;}public void setPatient_hamd(int patient_hamd) {this.patient_hamd = patient_hamd;}public String getPatient_age() {return patient_age;}public void setPatient_age(String patient_age) {this.patient_age = patient_age;}public String getCurrentdate() {return current_date;}public void setCurrentdate(String currentdate) {this.current_date = currentdate;}public int getId() {return id;}public void setId(int id) {this.id = id;}public String getPatient_name() {return patient_name;}public void setPatient_name(String patient_name) {this.patient_name = patient_name;}public String getPatient_gender() {return patient_gender;}public void setPatient_gender(String patient_gender) {this.patient_gender = patient_gender;}public String getPatient_postion() {return patient_postion;}public void setPatient_postion(String patient_postion) {this.patient_postion = patient_postion;}public String getPatient_scde() {return patient_scde;}public void setPatient_scde(String patient_scde) {this.patient_scde = patient_scde;}public String getPatient_insomnia() {return patient_insomnia;}public void setPatient_insomnia(String patient_insomnia) {this.patient_insomnia = patient_insomnia;}public String getPatient_mhistory() {return patient_mhistory;}public void setPatient_mhistory(String patient_mhistory) {this.patient_mhistory = patient_mhistory;}public String getPatient_phone() {return patient_phone;}public void setPatient_phone(String patient_phone) {this.patient_phone = patient_phone;}
}

PatientTest.java

package com.zghaikun.json;public class PatientTest {int id;String pqsi;String sleepness;String hama;String hamd;String isi;public String getIsi() {return isi;}public void setIsi(String isi) {this.isi = isi;}public PatientTest() {super();}public PatientTest(int id, String pqsi, String sleepness, String hama,String hamd,String isi) {super();this.id = id;this.pqsi = pqsi;this.sleepness = sleepness;this.hama = hama;this.hamd = hamd;this.isi = isi;}public int getId() {return id;}public void setId(int id) {this.id = id;}public String getPqsi() {return pqsi;}public void setPqsi(String pqsi) {this.pqsi = pqsi;}public String getSleepness() {return sleepness;}public void setSleepness(String sleepness) {this.sleepness = sleepness;}public String getHama() {return hama;}public void setHama(String hama) {this.hama = hama;}public String getHamd() {return hamd;}public void setHamd(String hamd) {this.hamd = hamd;}}

SleepDiary.java

package com.zghaikun.json;public class SleepDiary {private int id;private String day01;private String day02;private String day03;private String day04;private String day05;private String day06;private String day07;public SleepDiary(String day01, String day02, String day03, String day04,String day05, String day06, String day07) {super();this.day01 = day01;this.day02 = day02;this.day03 = day03;this.day04 = day04;this.day05 = day05;this.day06 = day06;this.day07 = day07;}public SleepDiary(int id, String day01, String day02, String day03,String day04, String day05, String day06, String day07) {super();this.id = id;this.day01 = day01;this.day02 = day02;this.day03 = day03;this.day04 = day04;this.day05 = day05;this.day06 = day06;this.day07 = day07;}public SleepDiary() {super();}public int getId() {return id;}public void setId(int id) {this.id = id;}public String getDay01() {return day01;}public void setDay01(String day01) {this.day01 = day01;}public String getDay02() {return day02;}public void setDay02(String day02) {this.day02 = day02;}public String getDay03() {return day03;}public void setDay03(String day03) {this.day03 = day03;}public String getDay04() {return day04;}public void setDay04(String day04) {this.day04 = day04;}public String getDay05() {return day05;}public void setDay05(String day05) {this.day05 = day05;}public String getDay06() {return day06;}public void setDay06(String day06) {this.day06 = day06;}public String getDay07() {return day07;}public void setDay07(String day07) {this.day07 = day07;}}

一个布局文件，由两个按键和一个textView组成，
activity_main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:tools="http://schemas.android.com/tools"android:layout_width="match_parent"android:layout_height="match_parent"android:orientation="vertical"><Buttonandroid:id="@+id/bt2" android:layout_width="match_parent"android:layout_height="wrap_content"android:text="把普通数据换成json数据格式的string"/><Buttonandroid:id="@+id/bt4" android:layout_width="match_parent"android:layout_height="wrap_content"android:text="解析带集合的json字符串"/><TextViewandroid:id="@+id/text"android:layout_width="wrap_content"android:layout_height="wrap_content"android:gravity="center"android:textSize="30sp"android:text="@string/hello_world" /></LinearLayout>

}

程序中先通过initDate()方法设置数据，再通过changeArrayDateToJson()函数将数据转换成json数据格式，转换后再通过changeJsonToData1()方法吧json数据转换成普通的数据，然后在进行下一步的操作。
