安卓：可以将片段添加到Viewflipper？ [英] Android: Possible to add a fragment to a Viewflipper?

问题描述

这是一些$ C $工作c，我发现自己有点咸菜。

Working on some code, I found myself in a bit of a pickle.

我有片段，以显示我的应用程序的各个页面。我有，我想彼此交互的搜索片段和一个选项片段。是有可能具有可以正常存取，并将它用viewflipper访问的片段？

I have fragments to display the various pages of my app. I had a search fragment and an options fragment which I want to interact with one another. Is it possible to have a fragment which can be accessed normally and have it accessed using a viewflipper?

Options（选项）片段中有一个viewflipper，让我来显示参与其中的各种菜单。不过，我需要能够通过选项片段viewflipper访问搜索功能，同时也能够访问它作为一个正常的片段（不是在同一时间，但既能够通过选项卡上的片段进行访问酒吧或从选项片段viewflipper）。

The Options Fragment has a viewflipper in it which allows me to display the various menus that are involved with it. However, I need to be able to access the search function through the viewflipper on the Options Fragment, whilst also being able to access it as a normal Fragment (Not at the same time, but able to access it either via the fragment on the tab bar or from the viewflipper in the options Fragment).

到目前为止，我已经用下面的code激活viewflipper看法的变化：

So far I have used the following code to activate a viewflipper view change:

    public void onItemClick(AdapterView<?> av, View v, int pos, long id) {
                        if(moreViewFlipper.getChildAt(1) != null)//Check if any previously checked views
                        {
                            moreViewFlipper.removeViewAt(1);
                        }
                        switch(pos){
                        case 0: // Profile
                            moreViewFlipper.addView(createProfileView(ctx), 1);
                            moreViewFlipper.setInAnimation(SlideAnimation.inFromRightAnimation());
                            moreViewFlipper.setOutAnimation(SlideAnimation.outToLeftAnimation());
                            moreViewFlipper.setDisplayedChild(1);
                            break;
...

是否可以使用code以上（加上片段的观点，作为一个孩子的moreViewFlipper？我将不胜感激，如果有人可以帮助我。

Is it possible to use the code above (adding the fragment's view as a child to the moreViewFlipper? I would be grateful if anyone could help me with this.

编辑：
一个朋友很慈祥设法指出，我怎么可能经过一些实验做到这一点。显然，这是可能的，如果你把它在保持你希望的片段添加到视图的XML文件放置在视图中的片段。

A friend very kindly managed to point out how I could do this after some experimentation. Apparently, it is possible to place a fragment within a view if you place it in the the xml file which holds the view which you wish to add the fragment to.

在这种情况下，我创建了一个新的XML文件，并放置在片段的Linearview内有后退按钮。我用上面的code调用哪个膨胀的观点和将其纳入viewflipper和voala功能！它只要你有一个不同的ID为您的片段作为你原来做的（如果是像我这样的情况下，被称为在两个实例）的作品。

In this case, I created a new xml file and placed the fragment inside a Linearview with a back button. I used the code above to call a function which inflated the view and brought it into the viewflipper and voala! it works as long as you have a different ID for your fragment as you do for the original one (if it is a case like mine, being called in 2 instances).

再次抱歉浪费别人的时间，但感谢你的好意。

Again, sorry for wasting people's time, but thank you for your kindness.

推荐答案

对不起，我迟到的反应。但其他人可能是有人有类似的问题。

Sorry for the late response. But may be someone else has a similar issue.

可以，如果你使用的是ViewPager结合ViewFlipper和片段。把ViewPager -node您ViewFlipper -node里面你main_layout.xml。操作栏仍然会留在它的地方，你就可以翻转到另一种观点很容易和倒退。

You can combine ViewFlipper and Fragments if you are using ViewPager. Put ViewPager -node inside your ViewFlipper -node in your main_layout.xml. The action bar will still stay on its place and you will be able to flip to the other view easily and backwards.

如果你想处理一个硬件后退按钮，把类似的东西在你的主片段活动：

If you want to handle a hardware back button, put something like that in your main fragment activity:

@Override
public boolean onKeyDown(int keyCode, KeyEvent event)
{
    if(keyCode == KeyEvent.KEYCODE_BACK)
    {
        if(this.vf.getCurrentView() != this.findViewById(R.id.pager))     //vf is a ViewFlipper's instance
        {
            this.vf.showPrevious();
            return true;
        }
    }

    return super.onKeyDown(keyCode, event);
}
