Android - ListView - performItemClick

Question

I\'m facing some difficults when I try to use the performItemClick funcion of the ListView.

All I want to do is to perform a click programatically i

Answer 1

Dropping Some Experience.

using listview1.performItemClick, will also trigger your listview1.OnItemClickListener if you are using the listener with same listview in your code.

Hope It helps  

Answer 2

this may be old but this may help :

lvList.performItemClick(null, index, lvList.getItemIdAtPosition(index) ); 

NOTE : the first param is null and will still work, if you have a custom adapter, convertView will be filled with custom layout and view and such.

-cheers / happy codings.

Using the code @sulal proposed, you may place it in onLoadFinished, if you use a LoaderManager. Eg something like

@Override
public void onLoadFinished(Loader<Cursor> loader, Cursor data) {
    //....
    // mSelectedId keeps the currently selected id
    // INVID is an invalid value
    if (mSelectedId == INVID) { // nothing selected
        // sulal's code
        new Handler().post(new Runnable() {
            @Override
            public void run() {
                mList.performItemClick(
                        mList.getChildAt(mActivePosition),
                        mActivePosition,
                        mList.getAdapter().getItemId(mActivePosition));
                mSelectedId = mList.getAdapter().getItemId(mActivePosition);
            }
        });            
    }

mActivePosition may be 0 (ie position on the first item) or a position kept during eg onPause

This worked for me:

listView.getAdapter().getView(1, null, null).performClick();

Answer 5

This is from Begining Android Games. It creates a simple list of items which you can click to open a new activity. Each list item of course, would have to also be added to the AndroidManifest.xml as a separate activity with a .ListItem# name.

public class MainActivity extends ListActivity {
String tests[] = { "ListItem1",
                   "ListItem2",
                   "ListItem3",
                   "ListItem4"};

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setListAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, tests));
}

@Override
protected void onListItemClick(ListView list, View view, int position, long id) {
    super.onListItemClick(list, view, position, id);
    String testName = tests[position];

    try {
        Class<?> classInstance = Class.forName("your.package.name." + testName);
        Intent intent = new Intent(this, classInstance);
        startActivity(intent);
    } catch (ClassNotFoundException e) {
        e.printStackTrace();
    }
}

}

Answer 6

I went with

listView.getAdapter().getView(position, null, null).performClick();
