Add Items from a EditText into a ListView sample App in Android

I have a Problem with my thinking. I have 2 Actvities:

As you can see there are EditText Widgets in the second Activity. I want now that the content of them gets saved in the ListView of the MainActivity by pressing the floating action button in MainAddMedActivity.

I tried to use an adapter but i couldn't figure it out. Hope you can help me. I am using an extra xml for the layout in the list.

This is so far what I have:

  1. MainActivity:

    protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);


FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {

        Intent intent = new Intent(view.getContext(), MainAddMedActivity.class);
        startActivity(intent);
    }
});


ListView mainListView = (ListView) findViewById(R.id.listView);
listAdapter = new ArrayAdapter<String>(this, R.layout.single_row);
mainListView.setAdapter(listAdapter);


String bIntent = getIntent().getExtras().getString("CONTENT_SEARCH_MED"); //And now?

}

  2. MainAddMedActivity

    private EditText txtSearchMedicament;
private EditText txtNumberMedicament;

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_add_med);

FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        EditText description = (EditText) findViewById(R.id.txtSearchMedicament);
        String text = description.getText().toString();
        // Now what?!
    }
});

getSupportActionBar().setDisplayHomeAsUpEnabled(true);

this.txtSearchMedicament = (EditText) findViewById(R.id.txtSearchMedicament);
this.txtNumberMedicament = (EditText) findViewById(R.id.txtNumberMedicament);

Intent i = new Intent(this, MainActivity.class);
i.putExtra("CONTENT_SEARCH_MED", txtSearchMedicament.getText().toString());
i.putExtra("CONTENT_MED_NR", txtNumberMedicament.getText().toString());

}

You need to use "startActivityForResult()" method. Following link explains perfectly.

Only one Activity can be active at a time, so you'll have to store the data in SharedPreferences or a database and reload it when MainActivity resumes.
