android - xml - 多次包含相同的布局不起作用

I'm trying to include the following layout twice:

我试图将以下布局包括两次：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >

<com.viewpagerindicator.TabPageIndicator
    android:id="@+id/indicator"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />

<android.support.v4.view.ViewPager
    android:id="@+id/pager"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />

like the following

如下

<include
    android:id="@+id/include1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    layout="@layout/view_pager" />

<include
    android:id="@+id/include2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    layout="@layout/view_pager" />

Actually, the second view pager does not work if I do it like that... The second view pager always stays empty... If I copy my view_pager layout and change the ids in this layout (pager to pager2 and indicator to indicator2) everything works fine. Is there a better way to do that? Copying layouts to achieve that seems to make the include useless for multiple includes of the same layout....

实际上，如果我这样做，第二个视图寻呼机不起作用...第二个视图寻呼机总是保持空...如果我复制我的view_pager布局并更改此布局中的ID（寻呼机到pager2和指示器到指示器2）一切正常。有没有更好的方法呢？复制布局以实现这似乎使包含无用的多个包括相同的布局....

I'm getting the references correctly I think, but though it just does not work if I include the same layout...

我认为我正确地得到了参考文献，但是如果我包含相同的布局它只是不起作用...

pager1= (ViewPager)(findViewById(R.id.include1).findViewById(R.id.pager));
pager2= (ViewPager)(findViewById(R.id.include2).findViewById(R.id.pager));

Everything works perfectly if I copy the layout...

如果我复制布局，一切都很完美......

Edit:

编辑：

I think it has to do with the FragmentManager, because the view pagers have the same id... But I don't know how to solve that correctly...

我认为它与FragmentManager有关，因为视图寻呼机具有相同的ID ...但我不知道如何正确解决...

Yes it can be done. You can inflate the layout many times, but you have to make the inclusion programmatically. See the answer to same kind of question.

是的，它可以做到。您可以多次为布局充气，但必须以编程方式进行包含。查看同类问题的答案。
