pass value from first activity to fourth activity in android

Question

Hi this is my singlemenuitemactivity:

here my doubt is the orderid is parsed from xml parsing...the update operation is performed soap calling..now here i have to update the status from orderid...how is to do..this is my update query.

"UPDATE `xcart_orders` set `status` = '"+Status+"' where `orderid` = '"+Orderid+"'"

please help me...how is update status depends upon orderid from xml parsing..how is change my code...how is to do...please help me

Use [SharedPreferences](http://developer.android.com/reference/android/content/SharedPreferences.html) for this.. — user370305, Sep 03 '12 at 12:47
please read my updated question...exactly i need answer for this question.it is possible — Krishna Veni, Sep 03 '12 at 13:06
the first singlemenuactivity is perform xml parsing....the insertionexample is perform soap calling...but i wish to get the orderid from xml parsing and use it in update status in insertionexample — Krishna Veni, Sep 03 '12 at 13:08

Use shared preferences or Application class

You have 2 ways to do this:

1- Use public static values to store username and password (not recommended)

2- Use sharedPreferences as below:

in your first activity, to save username and password:

SharedPreferences data = PreferenceManager.getDefaultSharedPreferences(getBaseContext());
data.edit().putString("UserName", userName).commit();
data.edit().putString("Password", password).commit();

in the fourth activity to retrieve username and password:

SharedPreferences data = PreferenceManager.getDefaultSharedPreferences(getBaseContext());
String userName = data.getString("UserName", "THIS IS DEFAULT VALUE");
String password = data.getString("Password", "THIS IS DEFAULT VALUE");

You can Do this using the Getters and setters methods.

create one class :

public class SelectedAnswer {

public static String uname;

public static String getAnswer() {
    return uname;
}

public static void setAnswer(String answer) {
    uname = answer;
}

}

Then set the username value into your first activty.

 SelectedAnswer.setAnswer(uName);

and get the value into fourth activity.

String answer = SelectedAnswer.getAnswer();

you can also use setter getter class to set data and access data anywhere in application by just creating object for that class. in your case this might be useful.

If you have data which must be accessed from different parts of your application you can use Singleton pattern as data holder.

Either use some static variables to store this or use shared preference. If you have more than one activty where you need to transfer data, its better to use a static dictionary which will help you to save activity specific data.

For Example :

We can create a simple data cacher class for this :

public class MyActivityDataCacher {

private static HashMap<String, String> mDataCacher;

    static{
    mDataCacher=new HashMap<String, String>();
}

public static void putDataFor(String className, String data) {
    mDataCacher.put(className, data);
}

public static String getDataFor(String className) {
    if (mDataCacher.containsKey(className)) {
        return mDataCacher.get(className);
    } else {
        return "";
    }
}
}

For storing Data for a particular Activity (Say MainActivity) :

MyActivityDataCacher.putDataFor(MainActivity.class.getName(), "Test Data");

For Retrieving the data stored :

MyActivityDataCacher.getDataFor(MainActivity.class.getName());

pass value from first activity to fourth activity in android
