Choose Only Selected Json Value And Save In Sharedpreferences?

I am Able to Parse JSON Data.Exactly what is the issue is that ,i want to store the Student ID in the SharedPreference without suffix i.e means only the integer is to be stored? I

Solution 1:

The best way to pars a JSON is by using Gson. U can add it to your project in your gradle:

compile'com.google.code.gson:gson:2.2.+'

Then you can easily create your model:

-----------------------------------com.example.Example.java-----------------------------------

package com.example;

import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;

publicclassExample{

@SerializedName("StdID")@Exposeprivate String stdID;
@SerializedName("NAME")@Exposeprivate String nAME;
@SerializedName("PHONENO")@Exposeprivate String pHONENO;

}

public void setNAME(String nAME) {

public Object getMarks() {

public StdCategory getStdCategory() {

public void setStdCategory(StdCategory stdCategory) {

}

public String getLastName() {
return lastName;

}

public String getRelation() {

}

public void setRelation(String relation) {

}

}

public String getEmail() {

public String getAddLine1() {

}

public void setAddLine1(String addLine1) {
this.addLine1 = addLine1;
}

public String getAddLine2() {
return addLine2;

}

public void setState(String state) {
this.state = state;
}

public String getCountry() {
return country;
}

public void setCountry(String country) {
this.country = country;
}

}

After that, just with fromJson() method, you can convert any json to your model and retrieve your stdId from it.

UPDATE:

If you want to get only the number from S001 you can do it this way:

Stringstr = "S001";
str = str.subString(1);

after this, you have your number in str.
