Question

i am new to Android development. I have two activities A and B. In activity A I use a xml parser to gain objects with each about 10 strings included. I want to pass these objects to activity B and there should be a listview showing all the objects. Clicking on a object in the listview should show the 10 strings.

I am not sure if I have to use a SQLite database or if I only can use SharedPreferences?
Or can I even store it on the internal memory?

The objects should be saved even if i kill the app.

Hope someone can give me some hints, thanks!

Answer 1

this may helps you

you can pass your string data both way as you like [1] Using Intent [2] Using Share Prefrence

like [1] Intent
in your First ActivityA

            Intent myintent= new Intent(FirstActivity.this,SecondActivity.class);
            myintent.putExtra("Name1", "your String");
            myintent.putExtra("Name2", "your String");
            myintent.putExtra("Name3", "your String");
            myintent.putExtra("Name4", "your String");
            startActivity(myintent);

in Second ActivityB

    Intent myintent = getIntent();
    if(null!=myintent.getExtras()){
    String Name1 = myintent.getExtras().getString("Name1");        
    String Name2 = myintent.getExtras().getString("Name2");        
    String Name3 = myintent.getExtras().getString("Name3");        
    String Name4 = myintent.getExtras().getString("Name4");        
    Toast.makeText(getApplicationContext(),""+Name,12).show();                              

    }
    else
    {
        Toast.makeText(getApplicationContext(),"No Recor Here..",12).show();

    }

like SharedPreferences[2]
in your First ActivityA

           Intent myintent= new Intent(FirstActivity.this,SecondActivity.class);
            SharedPreferences spref = this.getSharedPreferences("mynotifyid", MODE_WORLD_WRITEABLE);
            SharedPreferences.Editor spreedit = spref.edit();
            spreedit.putString("Name1", str1.toString());   
            spreedit.putString("Name2", str2.toString());   
            spreedit.putString("Name3", str3.toString());   
            spreedit.putString("Name4", str4.toString());   
            spreedit.commit();
            startActivity(myintent);

in your Second ActivityB

        SharedPreferences spref = context.getSharedPreferences("mynotifyid", Context.MODE_WORLD_WRITEABLE);
        String str1 = spref.getString("Name1","");
        String str2 = spref.getString("Name2","");
        String str3 = spref.getString("Name3","");
        String str4 = spref.getString("Name4","");

for your object saving purpose use SharedPreferences
