Try temporarily setting <a href="https://developer.android.com/reference/android/view/View.html#attr_android%3ascrollY" rel="nofollow"><code>android:scrollY</code></a> on the <code>ScrollView</code>. I haven't tried this but it should, in theory, work. Just remember to remove the attribute when publishing the app.

As of Android API 19 this solution has changed. 
Here's what worked for me. 

Go to your Android Virtual Device Manager (in Eclipse this is in Window > Android Virtual Device Manager), once there go to the Device Definitions tab and create a New Device. Name it something memorable like "Long Scroller". 

<img src="https://i.stack.imgur.com/lCbfN.png" alt="The Create New Device screen">

In the Edit/Create Device screen set the vertical dimensions to however long you think your scroll view will be (7000px was more than enough for my uses). You can also tweak it later. 

Restart Eclipse, open your long scrollview layout, and your long scroller will appear among your preview layouts.

Try setting your inner layout to a fixed height. So your code should be like

<pre><code>&lt;ScrollView
 android:layout_width="fill_parent"
 android:layout_height="fill_parent"&gt;
&lt;RelativeLayout
 android:layout_height="900dp"
&gt;
&lt;/ReleativeLayout&gt;
&lt;/ScrollView&gt;

This should work

blocks|key|234246|text|我通常只使用负边距。它在滚动视图上工作，就像在里面的项目上一样。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|234247|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I usually just use negative margin. It works on scroll view as on a item inside.

blocks|key|234319|text|这是我的解决方案:我继承了ScrollView的子类，以获取一个仅在isInEditMode()时使用的scrollY参数。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|234320|public+class+MyScollView+extends+ScrollView+{

This was my solution: I subclassed ScrollView to take a scrollY param that is only used when isInEditMode(). 

<pre><code>public class MyScollView extends ScrollView {

 private int scrollY = 0;

 private void init(Context context, AttributeSet attrs) {
 TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.MyScrollView);
 scrollY = a.getInt(R.styleable.MyScrollView_scrollY, 0);
 a.recycle();
 }

 public MyScollView(Context context, AttributeSet attrs, int defStyle) {
 super(context, attrs, defStyle);
 init(context, attrs);
 }

 public MyScollView(Context context, AttributeSet attrs) {
 super(context, attrs);
 init(context, attrs);
 }

 public MyScollView(Context context) {
 super(context);
 }

 @Override
 public void computeScroll() {
 if (isInEditMode()) {
 scrollTo(0, scrollY);
 }
 }

}
</code></pre>

This goes into your attrs.xml file

<pre><code>&lt;declare-styleable name="MyScrollView"&gt;
 &lt;attr name="scrollY" format="integer"/&gt;
&lt;/declare-styleable&gt;
</code></pre>

I've been using scroll view in my apps, but the thing is that this is the first time I've to draw something longer than the default size screen.

The XML Design screen shows a fixed 3.7inch (or larger) screen. What if I want to add more objects? How do I scroll down while designing in Eclipse?

Eclipse

我一直在我的应用程序中使用滚动视图，但问题是，这是我第一次绘制比默认屏幕更长的内容。XML设计屏幕显示一个固定的3.7英寸(或更大)屏幕。如果我想添加更多的对象怎么办？在Eclipse中设计时如何向下滚动？
