Productivity App(Help)

So to learn android development I've decided to create a simple productivity app. I've decided to start with a calendar. I have it where when you select a date it displays that with a text block. What I am trying to do now is to have it so you can create in event(appointment, upcoming birthday,etc) I've looked every where but people are giving mixed answers and some of them are old. Any ideas on how I can do this and if it can be done with the built in Calendarview?

 

So which one would you recommend?

 

So what if I change it up and have the events be shown in a list view and highlighted on the calendarview. Is that something I can do or no

 

Yeah its weird. Not sure why google wont allow you to add events to it. I figured the ListView way would probably be better. Can I make it so when you click on a date in the CalendarView it will take you to that event in the listview?

 

Ok so i've been looking around and found https://stackoverflow.com/questions/22144891/how-to-add-listview-items-on-button-click-using-adapter On the Activity part I am stuck at:

Code (Text):

1. public void onItemClick(AdapterView<?> a, View v, int position,
2.                     long id) {

Here is my code:

Code (Text):

1. package com.example.johnathan.myapplication;
2.  
3. import android.support.v7.app.AppCompatActivity;
4. import android.os.Bundle;
5. import android.view.View;
6. import android.widget.AdapterView;
7. import android.widget.ArrayAdapter;
8. import android.widget.Button;
9. import android.widget.EditText;
10. import android.widget.ListView;
11. import android.widget.Toast;
12.  
13. import java.util.ArrayList;
14.  
15. public class MainActivity extends AppCompatActivity {
16.     EditText editText;
17.     EditText editText2;
18.     Button addButton;
19.     ListView listView;
20.     ArrayList<String> listItems;
21.     ArrayAdapter<String> adapter;
22.  
23.     @Override
24.     protected void onCreate(Bundle savedInstanceState) {
25.         super.onCreate(savedInstanceState);
26.         setContentView(R.layout.activity_main);
27.         editText = (EditText) findViewById(R.id.editText);
28.         editText = (EditText) findViewById(R.id.editText2);
29.         addButton = (Button) findViewById(R.id.addItem);
30.         listView = (ListView) findViewById(R.id.listView);
31.         listItems = new ArrayList<String>();
32.         listItems.add("First Item - added on Activity Create");
33.         adapter = new ArrayAdapter<String>(this,
34.                 android.R.layout.simple_list_item_1, listItems);
35.         listView.setAdapter(adapter);
36.         addButton.setOnClickListener(new View.OnClickListener() {
37.             @Override
38.             public void onClick(View view) {
39.                 listItems.add(editText.getText().toString());
40.                 listItems.add(editText2.getText().toString());
41.                 adapter.notifyDataSetChanged();
42.             }
43.         });
44.         listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
45.             @Override
46.             public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
47.                 long id) {
48.                     Toast.makeText(MainActivity.this, "Clicked", Toast.LENGTH_LONG)
49.                             .show();
50.                 }
51.                 }
52.             }
53.         });
54. }
55.  

Im not sure why it looks different when I am using the "OnItemClickListener"

Any help would be appreciated. Thanks

 

It's not liking the "long id) {"

 

I've uploaded a screenshot for you.

 

So i removed that one and it's the same thing :/

So it now runs but when I try to add something, i cant even select the second text field and when I hit the add button it crashes
