Android的 - 在的LinearLayout的滚动型的RelativeLayout [英] Android - LinearLayout in ScrollView in Relativelayout

问题描述

我有布局有点问题。
我曾在RelativeLayout的，我把两个LinearLayouts（1和2）以及它们之间的滚动型与LinearLayout中。接下来，我设置为滚动型下linearLayout2及以上linearLayout1放置。但是，随着它的父的滚动型里面的LinearLayout未设置。

I have a little problem with layouts. I have made RelativeLayout in which I put two LinearLayouts (1 and 2) and between them ScrollView with LinearLayout. Next I set that ScrollView to be placed under linearLayout2 and above linearLayout1. But LinearLayout inside that ScrollView isn't set as it's parent.

这里的code，也许我犯了一个错误：

Here's the code, maybe I've made a mistake:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content">

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"        
        android:padding="6dip"
        android:layout_alignParentTop="true"
        android:id="@+id/lin1"
        android:layout_weight="1">

</LinearLayout>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent"
        android:layout_alignParentBottom="true"
        android:layout_weight="1" android:id="@+id/lin3" 
        android:layout_height="60dip">          

</LinearLayout>

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" 
android:scrollbars="horizontal"
android:layout_below="@id/lin1"
android:layout_above="@id/lin3" android:id="@+id/ScrollView">

<LinearLayout
        android:layout_width="fill_parent"                      
        android:orientation="vertical"
        android:id="@+id/lin2" 
        android:layout_height="fill_parent"  
        android:layout_gravity="center_vertical|center_horizontal">

    <Button android:text="@string/button1" 
        android:id="@+id/button1" 
        android:layout_gravity="center" 
        android:layout_width="280dip" 
        android:layout_height="60dip">
    </Button>

    <Button android:text="@string/button2"
        android:id="@+id/button2" 
        android:layout_gravity="center" 
        android:layout_width="280dip" 
        android:layout_height="60dip">
    </Button>

    <Button android:text="@string/button3" 
        android:id="@+id/button3" 
        android:layout_gravity="center" 
        android:layout_width="280dip" 
        android:layout_height="60dip">
    </Button>

    <Button android:text="@string/button4"
        android:id="@+id/button4" 
        android:layout_gravity="center" 
        android:layout_width="280dip" 
        android:layout_height="60dip">
    </Button>


</LinearLayout>
</ScrollView>

任何想法，为什么里面的LinearLayout滚动型的比滚动型大？

Any ideas, why LinearLayout inside of ScrollView is bigger than the ScrollView?

编辑：
到目前为止，我已经注意到，滚动型的LinearLayout里面当我设置layout_gravity =center_vertical移动之外。它看起来像设置中心是指主要布局（RelativeLayout的）。

So far I've noticed that LinearLayout inside of ScrollView moves outside when I set layout_gravity="center_vertical". It looks like setting center refers to main layout (RelativeLayout).

推荐答案

好吧，我已经做到了。
所有我必须做的是设置的LinearLayout是滚动型的内部

Ok, I've made it. All I had to do is setting LinearLayout that is inside of ScrollView to

layout_width="wrap_content"
layout_gravity="center_horizontal"
android:orientation="vertical"

滚动视图，以

layout_width="fill_parent"
layout_gravity="center_horizontal"
layout_height="wrap_content"

而在结束时，我已经把那个滚动型到新的LinearLayout中带参数如下：

And at the end I've put that ScrollView into new LinearLayout with parameters as following:

layout_width="fill_parent" 
layout_height="fill_parent" 
gravity="center_vertical" 
orientation="vertical"

所以滚动型和它的子布局horizo​​ntaly设定按钮中心和外部的LinearLayout是verticaly设置它们中心。 ： - ）

So the ScrollView and it's child Layout are setting buttons center horizontaly and the outer LinearLayout is setting them center verticaly. :-)
