Question

I’ve an application where a user creates events. The user need to retrieve a certain name from an activity which is a ListView of names list.

I’m having an issue with making sure that a name should remain in an activity after clicking a date button which links to another activity(calendar activity), then return back to the current activity.

My codes of the 3 pages:

Create_Events.java – codes for getting a certain name from ListView activity and the btnDate onClickListener which links to the another activity(calendar activity)

Bundle bundle = getIntent().getExtras();  
        if(bundle != null)
        {

            String date = bundle.getString("date");

            txtDate.setText(date);  

        }

        Bundle b = getIntent().getExtras();
        if(b != null)
        {
            String name = bundle.getString("name");
            txtName.setText("Create an event for:" +name);
        }

buttonDate = (Button) findViewById(R.id.btnDate);
        buttonDate.setOnClickListener(new View.OnClickListener()
        {

            @Override
            public void onClick(View v)
            {
                Intent calIntent = new Intent(Create_Events.this, Calendar_Event.class);
                startActivity(calIntent);


            }

        });


ContactsList.java --  the ListView of the names which is passed to the Create_Events page.

    Cursor cursor = null;

               cursor = (Cursor) l.getItemAtPosition(position);
               Intent intent = new Intent(ContactsList.this, Create_Events.class);
               intent.putExtra("name", cursor.getString(cursor.getColumnIndex(buddyDB.KEY_NAME)));
               startActivity(intent);

I need help with this.
Any help provided will be greatly appreciated. Thanks in advance! =)

Answer 1

you can use SharedPreferences to store the name while use bundle to store the date.

From contactLists.java add these codes

private void SavePreferences(String key, String value)
{
    SharedPreferences sharedPref = getSharedPreferences("MY_SHARED_PREF", MODE_PRIVATE);
    SharedPreferences.Editor editor = sharedPref.edit();
    editor.putString(key, value);
    editor.commit();
}

private void LoadPreferences()
{
    SharedPreferences sharedPref = getSharedPreferences("MY_SHARED_PREF", MODE_PRIVATE);
    String name = sharedPref.getString("name", "");



} 

Then set the name to the textView which will show on the listView. And then load the preference in the create_events page and the name will be shown even when you go to another activity.
Do inform me if you still have any questions. (:
