首先：

 

getActionBar().setDisplayShowTitleEnabled(false);		ActionBar.LayoutParams lp = new ActionBar.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.MATCH_PARENT);		lp.gravity = lp.gravity & ~Gravity.HORIZONTAL_GRAVITY_MASK | Gravity.LEFT;		ActionBarPopupButton popupButton = new ActionBarPopupButton(this);		popupButton.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {			@Override			public boolean onMenuItemClick(MenuItem item) {				Intent intent = new Intent();				intent.setClass(MainActivity.this, cls[item.getOrder()]);				intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);				if (item.getOrder() == 0) {					intent.putExtra(Extras.DATE, mDates.get(mViewPager.getCurrentItem()));				}				startActivity(intent);				return false;			}		});		getActionBar().setCustomView(popupButton, lp);		int change = getActionBar().getDisplayOptions() ^ ActionBar.DISPLAY_SHOW_CUSTOM;		getActionBar().setDisplayOptions(change, ActionBar.DISPLAY_SHOW_CUSTOM);

private Class<?>[] cls = new Class[] { HistoryActivity.class, VibrateActivity.class, CircleActivity.class, PersonalActivity.class, DeviceActivity.class };

 

第二：

public class ActionBarPopupButton extends Button implements OnClickListener {	private PopupMenu mPopupMenu;	public ActionBarPopupButton(Context context) {		super(context);		setBackgroundResource(R.drawable.abc_spinner_ab_holo_dark);		setTextAppearance(getContext(), android.R.style.Widget_Spinner);		setText(getContext().getString(R.string.title_activity_detail));		setTextColor(getResources().getColor(R.color.white));		setOnClickListener(this);		mPopupMenu = new PopupMenu(getContext(), this);		mPopupMenu.inflate(R.menu.main_navigation_list);	}	@Override	public void onClick(View v) {		mPopupMenu.show();	}	public void setOnMenuItemClickListener(OnMenuItemClickListener listener) {		mPopupMenu.setOnMenuItemClickListener(listener);	}}
