doesn't call onMenuItemClick for first time -

I use SherlockListActivity, I created ActionBar with one item & its clickListener when i click on it for first time after creating activity, doesn't call onMenuItemClick, but in every click after first click, work with no problem

Why ?

private void BuildTopActionBar() {
        BitmapDrawable bg = (BitmapDrawable) getResources().getDrawable(
                R.drawable.ic_action_bg);
        bg.setTileModeXY(TileMode.REPEAT, TileMode.REPEAT);
        getSupportActionBar().setBackgroundDrawable(bg);

        this.getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        this.getSupportActionBar().setHomeButtonEnabled(true);
        this.getSupportActionBar().setTitle("bookmarks");
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
        case android.R.id.home:
            // This is called when the Home (Up) button is pressed in the Action Bar.
            finish();
            return true;
        case add_bookmark_item:
            // add
            item.setOnMenuItemClickListener(new OnMenuItemClickListener() {

                public boolean onMenuItemClick(MenuItem item) {
                    customAmbilWarnaDialog dialog = new customAmbilWarnaDialog(
                            BookMarksActivity.this, 0xffffffff,
                            new OnAmbilWarnaListener() {

                                public void onCancel(
                                        customAmbilWarnaDialog dialog) {
                                }

                                public void onOk(customAmbilWarnaDialog dialog,
                                        int color, String name, int hasName) {
                                    myDbHelper.AddNewBookmark(name,
                                            currentPageNum, color, hasName);
                                    // code
                                    lv.smoothScrollToPosition((lv.getCount() - 1));
                                }
                            });
                    dialog.show();                  
                    return true;
                }
            });

        }

        return super.onOptionsItemSelected(item);

    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {

        menu.add(0, add_bookmark_item, 0, "add bookmark")
                .setIcon(R.drawable.bookmark_add)
                .setShowAsAction(
                        MenuItem.SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW
                                | MenuItem.SHOW_AS_ACTION_ALWAYS);

        return true;
    }

the reason is that you're calling the item.setOnMenuItemClickListener(new OnMenuItemClickListener() {... in the onOptionsItemSelected() method.

This means it will be set the first time you click the menuItem (and then reset on every click) and the code inside it will only run once you've clicked it at least once.

either call this in onCreateOptionsMenu() or simply move the code from onMenuItemClick() to the switch/case
