Question

I a new to Android development, so this is kind of a basic question.

I would like to implement the same behavior as in the Contacts app. You have a ListView with a series of Contacts | phone icons. There you have one behavior when you click on the contact name, and another behavior when you click on the phone icon.

Here is my code.
Any help is much appreciated.

In summary, what is wrong with the approach

switch (v.getId()) {
case R.id.imageButtonAction:

Activity Class

public class CompaniesActivity extends Activity  {

MyApp app;

ListView listCompanies;

Cursor cursor;

// Adapter and its corresponding FROM and TO statements. The number and sequence of the arguments must match in FROM / TO arguments.
SimpleCursorAdapter adapter;
static final String[] FROM = { MenuNavigationData.C_COMPANY, MenuNavigationData.C_DESCRIPTION};
static final int[] TO = { R.id.textCompany, R.id.textDescription }; //

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

    //Gets a reference to the application
    app = (MyApp) getApplication();

    // Find your views
    listCompanies = (ListView) findViewById(R.id.listCompanies);

    addButton = (Button) findViewById(R.id.buttonAdd);

    // Add actions to user interaction
    listCompanies.setOnItemClickListener(new OnItemClickListener() {
        @Override
        **public void onItemClick(AdapterView<?> arg0, View v, int position, long id) {


            switch (v.getId()) {
                case R.id.imageButtonAction:
                    startActivity(new Intent(app, InstructionsActivity.class));
                    break;
                default:
                    int i = adapter.getItemViewType(position);
                    startActivity(new Intent(app, EditMenuNavigationActivity.class));
                    break;
            }**

        }
    });

}

<!-- Action ImageView -->

New much better approach to solve this issue elegantly, and with less code!!!

With the following modifications, the User interface is much more responsive, no more double-clicking issues. 🙂

Much, much less code that simply works!

Modifications to Row xml

Insert a Linear layout to wrap both the

In this Linear layout, insert a tag named android:onClick=”editCompanyClick”
This is the click handler that will be called in the Activity.

In this Linear layout, insert a tag named android:onClick=”dialClick”

Modifications to Activity class

Remove the previous code

   listCompanies.setOnItemClickListener(new OnItemClickListener() { @Override public void    onItemClick(AdapterView arg0, View v, int position, long id) {

            TextView company = (TextView) v.findViewById(R.id.textCompany);
            ImageView dial = (ImageView) v.findViewById(R.id.imageButtonDTMFDial);

            company.setOnClickListener(new OnClickListener() {
                @Override
                public void onClick(View v) {
                    startActivity(new Intent(app, EditMenuNavigationActivity.class));
                }
            });

            dial.setOnClickListener(new OnClickListener() {
                @Override
                public void onClick(View v) {
                    startActivity(new Intent(app, InstructionsActivity.class));
                }
            });
        }

Insert the code

public void dialClick(View v) {
        startActivity(new Intent(app, InstructionsActivity.class));
    }

    public void editCompanyClick(View v) {
        startActivity(new Intent(app, EditMenuNavigationActivity.class));
record
    }
