为什么这样布局的上半部分不显示？ [英] Why upper part of this layout does not display?

问题描述

下面是我的布局。的问题是，无论是PageViewer内容是可见的，并没有别的。如果我看到PageViewer来走了，比我看到的一切都在它上面。也试过根布局，框架布局，但它并不能帮助。最主要的是只有视图寻呼机是可见的。我要的是2/3 ViewPager内容包含数据，以上就是1/3一些头的材料。我不想使用权重的上半部分已经是正确的大小。我只是想确保顶部和pageviewer正常显示。是不是因为他们的一切切换的pageviewers一个特点呢？或者他们不低于另一个元素被应用？

我想这Vie​​wPager通吃的空间，所以我使用的RelativeLayout把它放在页眉下方及以上页脚

Here is my layout. The problem is that either the PageViewer contents are visible and nothing else. If I see PageViewer to gone than I see everything above it. Also tried root layout as frame layout but it does not help. Main thing is only the view pager is visible. What I want is 2/3 ViewPager contents which contains data, and above some header material that is 1/3. I don't want to use weights as the upper part is already sized correctly. I just want to guarantee that both the top and pageviewer display properly. Is it a characteristic of pageviewers that they switch everything? or can they not be applied below another element?

解决方案

You can try something like this:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:orientation="vertical"
    android:layout_height="match_parent" >
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/mHeaderHeader"
        android:visibility="visible"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_alignParentTop="true"
        android:orientation="vertical">

        <include
            android:id="@+id/myInclude"
            layout="@layout/myInclude_layout" />

        <include
            android:id="@+id/myInclude2r"
            layout="@layout/myInclude2" />

        <include
            android:id="@+id/myInclude3"
            layout="@layout/myinclude3layout" />

        <ImageView
            android:id="@+id/myImageView"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            />

    </LinearLayout>

    <include layout="@layout/myinclude4"
        android:id="@+id/myinclude4" />

    <android.support.v4.view.ViewPager
        android:id="@+id/myViewPager"
        android:visibility="visible"
        android:layout_width="match_parent" 
        android:layout_height="wrap_content"
        android:layout_alignBelow="@id/mHeaderHeader"
        android:layout_alignAbove="@id/myinclude4" />

 </RelativeLayout>

I suppose that ViewPager takes all space, so I placed it below header and above footer using RelativeLayout
