滚动型不滚动到边距底部 [英] Scrollview doesn't scroll to the margin at the bottom

问题描述

我有一个简单的布局如下：

I have a simple layout as follows :

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#D23456" >

    <LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_margin="10dp"
    android:background="#FFFFFF" >

        <ImageView
            android:layout_width="match_parent"
            android:layout_height="800dp"
            android:src="@drawable/ic_launcher" />
    </LinearLayout>

</ScrollView>

滚动视图的背景是粉红色和线性布局里面有Android的图标图像具有800DP的高度（这并不适合屏幕）。我很期待看到的是，ImageView的漂浮在粉红色与10dp的每一个侧面保证金背景（上，下，左，右）。但是，当我滚动至底部，滚动视图不滚动到缘，因此，涡旋件的底部是ImageView的不粉色余量

The background of the scrollview is pink and linear layout inside has the android icon image with a height of 800dp (that doesnt fit to the screen) . What I'm expecting to see is that imageview floats in a background of pink with a margin of 10dp in every sides (top,bottom,left,right).But when I scroll to the bottom, the scrollview doesn't scroll to the margin, so the bottom of the scroll is the imageview not the pink margin.

我如何prevent呢？这使得用户认为网页尚未结束，使他想要滚动了。

How can I prevent this? This makes the user think the page hasn't ended yet and makes him want to scroll more.

推荐答案

我后来发现，类似的情况已经在下面的线程的http://stackoverflow.com/a/16885601/1474471 通过@olefevre。

I later found out that ,a similar situation has already been answered in the following thread http://stackoverflow.com/a/16885601/1474471 by @olefevre.

添加以填充围绕当前的LinearLayout一个额外的LinearLayout和去除内的LinearLayout布局利润率解决了这个问题：

Adding an extra LinearLayout that surrounds the current LinearLayout with a padding and removing the inner LinearLayout's layout-margin solved the problem:

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="#D23456"
    android:padding="10dp" >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="#FFFFFF" >

        <ImageView
            android:layout_width="match_parent"
            android:layout_height="800dp"
            android:src="@drawable/ic_launcher" />
    </LinearLayout>
</LinearLayout>

</ScrollView>
