是否可以將Android ActionBar放在底部？

Question

我正在開發一個應用程序到Android平板電腦（XOOM），我想知道是否可以將操作欄放在屏幕底部，而不是頂部（這是默認選項）。

謝謝。

Answer 1

如果您在活動中獲得ActionBar，則可以將此android：uiOptions =「splitActionBarWhenNarrow」添加到該特定活動的清單中。

這對我有效:)

是的，這是可能的，嘗試這個。

public void setActionBArAtBottom(View layoutView, Intent intent, 
      Context context, ContentValues componentIds) throws Exception { 
     if (componentIds != null) { 
      setValues(componentIds); 
     } else { 
      System.out 
        .println("Provide appropriate information to set ActionBar at bottom"); 
      try { 
       throw new UnsufficientResourcesException(); 
      } catch (UnsufficientResourcesException e) { 
       e.printStackTrace(); 
      } 
     } 
     // getting the parent of screen..actually this is the child of root 
     // parent... 
     ViewGroup screenParent = (ViewGroup) layoutView.getParent().getParent(); 
     // now getting actionbarview...as follows... 
     View actionBArView = ((ViewGroup) screenParent.getChildAt(0)) 
       .getChildAt(0); 
     // now getting framelayout that is custom layout to display actionbar at 
     // the bottom... 
     FrameLayout customActionBarFrameLayout = (FrameLayout) layoutView 
       .findViewById(BOTTOM_ACTION_BAR_LAYOUT_ID); 
     // now remove actionbarView from its parent view... 
     ViewGroup actionBarViewParent = removeFromParent(actionBArView); 
     removeTitleAndIcon((ViewGroup) actionBArView); 
     // now setting actionbar view to the framlayout... 
     customActionBarFrameLayout.addView(actionBArView); 

     // get the custombar layout.... 
     View customTitleBarLayout = LayoutInflater.from(context).inflate(
       NEW_TITLE_BAR_LAYOUT, null); 
     // setting icon to titile bar... 
     ((ImageView) customTitleBarLayout.findViewById(NEW_TITLE_ICON__ID)) 
       .setImageDrawable(getActivityIcon(intent, context)); 
     // setting title... 
     ((TextView) customTitleBarLayout.findViewById(NEW_TITLE_ID)) 
       .setText(((SherlockActivity) context).getTitle()); 
     // now set this layout to 
     actionBarViewParent.addView(customTitleBarLayout); 

    } 

    // method use to remove child from its parent... 
    private ViewGroup removeFromParent(View child) { 
     // removing child... 
     ViewGroup parentGroup = (ViewGroup) child.getParent(); 
     parentGroup.removeView(child); 
     return parentGroup; 
    } 

    // this method will set application icon to custom title bar layout... 
    private Drawable getActivityIcon(Intent intent, Context context) { 
     // getting the current activity icon set... 
     Drawable drawable = null; 
     try { 
      drawable = context.getPackageManager().getActivityIcon(intent); 
     } catch (NameNotFoundException e) { 
      e.printStackTrace(); 
     } 
     return drawable; 
    } 

    // remove title and icon from bottombar... 
    private void removeTitleAndIcon(ViewGroup actionBarViewGroup) { 
     actionBarViewGroup.removeAllViews(); 
    } 

    private void setValues(ContentValues contentValues) throws Exception { 
     try { 
      BOTTOM_ACTION_BAR_LAYOUT_ID = contentValues 
        .getAsInteger(BOTTOM_ACTION_BAR_FRAME_LAYOUT_ID); 
      NEW_TITLE_BAR_LAYOUT = contentValues 
        .getAsInteger(NEW_TITLE_BAR_LAYOUT_ID); 
      NEW_TITLE_ICON__ID = contentValues 
        .getAsInteger(NEW_TITLE_ICON_IMAGEVIEW_ID); 
      NEW_TITLE_ID = contentValues.getAsInteger(NEW_TITLE_VIEW_ID); 
     } catch (Exception e) { 

      throw new UnsufficientResourcesException(); 

     } 
    } 
}
