请检查以下法规: 在清单中利用你可以创造环境:

Create Function

@Override
public boolean onContextItemSelected(MenuItem item) {

    int menuItemId = item.getItemId();

    //to find out the id
    AdapterView.AdapterContextMenuInfo menuInfo = (AdapterView.AdapterContextMenuInfo) item.getMenuInfo();

    int currentSelectionItemPosition = menuInfo.position;

    //moving the cursor to the selected position in the list view
    restaurantFavoritesCursor.moveToPosition(currentSelectionItemPosition);
    int restaurantid = restaurantFavoritesCursor.getInt(idColumnIndex);

    if(menuItemId == R.id.deleteFavoriteRestaurant)
    {
        //write the Action
    }
    return true;
}

Register the event in Oncreate or Inside the OnStart

registerForContextMenu(listviewobject);

我希望这部法律将发挥作用。
