How can I get the text values out of these array list items when I click on share button

Issue

I have an array list of items presented in a list view. What I am trying to do is get the string value of the parameters of an array list value to put into a share intent when I click a share button.

Here is my REVISED code based on the inputs and suggestions I have recieved so far:

public class MainActivity extends AppCompatActivity {

    private String TAG = MainActivity.class.getSimpleName();
    private ListView lv;
    //public String term = null;
    public String url;
    public EditText editTextInput;

    ArrayList<HashMap<String, String>> itemList;

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

        editTextInput = (EditText) findViewById(R.id.editTextInput);

        itemList = new ArrayList<>();
        lv = (ListView) findViewById(R.id.list);

        //new GetSearchItems().execute();
    }

    public void onSearchClick(View v)
    {
//        String term = editTextInput.getText().toString();

        if (lv== null) {
            String term = editTextInput.getText().toString();
            url = "https://www.googleapis.com/customsearch/v1?key=AIzaSyA_Ee1WVjaHltF6B6wr2mkONXetYsy-ogU&cx=016799632979308504173:buxbhwd9nxm&q=" + term + "&gsc.sort=";

                        shareIntent.setAction(Intent.ACTION_SEND);
                        shareIntent.setType("text/plain");
                        shareIntent.putExtra(Intent.EXTRA_SUBJECT, title);
                        shareIntent.putExtra(Intent.EXTRA_TEXT, link + " " + snippet );
                        startActivity(Intent.createChooser(shareIntent, "Share Via"));

                    }
                }
            });
        }
    }

}

I am getting the following error in the debugger console when I click the share button:

java.lang.IllegalStateException: Could not find method onItemClick(View) in a parent or ancestor Context for android:onClick attribute defined on view class android.support.v7.widget.AppCompatButton with id 'sharebutton'

I cannot find out what I did incorrect based on the suggestions I received. What did I do wrong, and what's the best way to fix it?

Solution

This is how you will get the text values from your array list items and put them in an intent and further display them in a new activity if necessary. (Refer to code)

//-----------------------------------------------------------------------
// MainActivity.java
// This is how you will get the text values out of the array list items
// And create a share intent
//-----------------------------------------------------------------------

    protected void onPostExecute(Void result) {
        super.onPostExecute(result);

        // Adding menuItems to ListView
        ListAdapter adapter = new SimpleAdapter(MainActivity.this, itemList,
        R.layout.list_item,
        new String[] { "title","link", "snippet" }, new int[] {
        R.id.title, R.id.link, R.id.snippet });

        setListAdapter(adapter);

        // selecting single ListView item
        ListView lv = getListView();

        lv.setOnItemClickListener(new OnItemClickListener() {

    @Override
    public void onItemClick(AdapterView<?> parent, View view,
        int position, long id) {

        // getting values from selected ListItem
        String title = ((TextView) view.findViewById(R.id.title)).getText().toString();
        String link = ((TextView) view.findViewById(R.id.link)).getText().toString();
        String snippet = ((TextView) view.findViewById(R.id.snippet)).getText().toString();

        // Starting Share intent
        Intent shareIntent = new Intent();
        shareIntent.setAction(Intent.ACTION_SEND);
        shareIntent.setType("text/plain");
        shareIntent.putExtra(Intent.EXTRA_SUBJECT, title);
        shareIntent.putExtra(Intent.EXTRA_TEXT, link + " " + snippet );
        startActivity(Intent.createChooser(shareIntent, "Share Via"));
        }
        });
    }
