Set long click listener for listview

Question

I have below codes:

public class MainActivity extends ListActivity { 
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceSt         


        

Answer 1

You could implement the listener, then the callback would appear as a function (method) in your class:

public class MainActivity extends ListActivity implements View.OnLongClickListener {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        View listView = findViewById(R.id.list_view);
        listView.setOnLongClickListener(this);
    }

    @Override
    protected void onListItemClick(ListView l, View v, int position, long id) {
        super.onListItemClick(l, v, position, id);
    }

    @Override
    public boolean onLongClick(View v) {
        // Do your work here
        return false;
    }

}

Your question is very similar to this one, but it looks like it's not an exact duplicate.

What you've noticed is that the ListActivity class does not have a method override specifically for this case.

In order to add this functionality as a method override, your class should implement the AdapterView.OnItemLongClickListener interface, and then you can add the onItemLongClick() method override, which acts just as the onListItemClick() method override you already have, but responds to long clicks.

Just make sure that you follow instructions from this answer, you must use android:longClickable="true" in the layout xml, or call listview.setLongClickable(true);

Example:

public class MainActivity extends ListActivity implements AdapterView.OnItemLongClickListener {

    ListView listview;

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

        ListView listview = (ListView) findViewById(R.id.list);

        listview.setLongClickable(true);

    }

    @Override
    public boolean onItemLongClick(AdapterView<?> l, View v,
                                   final int position, long id) {

        Toast.makeText(this, "long clicked pos: " + position, Toast.LENGTH_LONG).show();

        return true;
    }

    protected void onListItemClick(ListView l, View v, final int position, long id) {
        super.onListItemClick(l, v, position, id);

        Toast.makeText(this, "short clicked pos: " + position, Toast.LENGTH_LONG).show();  

    }

you can simply do it with setOnItemLongClickListener

listview.setOnItemLongClickListener(new OnItemLongClickListener() {
        @Override
        public boolean onItemLongClick(AdapterView<?> arg0, View arg1,
                int arg2, long arg3) {
            Toast.makeText(ClassName.class, "Long Clicked Trigger: ", Toast.LENGTH_LONG).show();
            return true;
        }
});

Answer 4

try this

listView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {

        public boolean onItemLongClick(AdapterView<?> arg0, View v,
                int index, long arg3) {

             // write your code

            return false;
        }}); 

Answer 5

yes it is possible and quite easy to achieve, simply you have to make the instance of the listview like

ListView lv = (ListView)findViewById(R.id.listview);
lv.setOnLongClickListener(new View.OnLongClickListener() {
                @Override
                public boolean onLongClick(View 
                    // your code here
                    return true;
                }

        });)

in your case instead of extending ListActivity you can make a list view in xml and find the view in MainActivity and follow the above step.
