 public void run() { 
 mScrollView.scrollTo(0, mScrollView.getBottom());

blocks|key|643085|text|我想让scrollView直接在onCreateView()之后滚动(而不是在点击按钮之后)。要让它正常工作，我需要使用ViewTreeObserver：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|643086|mScrollView.getViewTreeObserver().addOnGlobalLayoutListener(new+ViewTreeObserver.OnGlobalLayoutListener()+{

I wanted the scrollView to scroll directly after onCreateView() (not after e.g. a button click). To get it to work I needed to use a ViewTreeObserver:

<pre><code>mScrollView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
 @Override
 public void onGlobalLayout() {
 mScrollView.post(new Runnable() {
 public void run() {
 mScrollView.fullScroll(View.FOCUS_DOWN);
 }
 });
 }
 });
</code></pre>

But beware that this will be called everytime something gets layouted (e.g if you set a view invisible or similar) so don't forget to remove this listener if you don't need it anymore with:

<code>public void removeGlobalOnLayoutListener (ViewTreeObserver.OnGlobalLayoutListener victim)</code> on SDK Lvl &lt; 16

or 

<code>public void removeOnGlobalLayoutListener (ViewTreeObserver.OnGlobalLayoutListener victim)</code> in SDK Lvl >= 16

I was using the Runnable with sv.fullScroll(View.FOCUS_DOWN);
It works perfectly for the immediate problem, but that method makes ScrollView take the Focus from the entire screen, if you make that AutoScroll to happen every time, no EditText will be able to receive information from the user, my solution was use a different code under the runnable:

sv.scrollTo(0, sv.getBottom() + sv.getScrollY());

making the same without losing focus on important views

Everyone is posting such complicated answers.

I found an easy answer, for scrolling to the bottom, nicely:

<pre><code>final ScrollView myScroller = (ScrollView) findViewById(R.id.myScrollerView);

// Scroll views can only have 1 child, so get the first child's bottom,
// which should be the full size of the whole content inside the ScrollView
myScroller.smoothScrollTo( 0, myScroller.getChildAt( 0 ).getBottom() );
</code></pre>

And, if necessary, you can put the second line of code, above, into a runnable:

<pre><code>myScroller.post( new Runnable() {
 @Override
 public void run() {
 myScroller.smoothScrollTo( 0, myScroller.getChildAt( 0 ).getBottom() );
 }
}
</code></pre>

It took me much research and playing around to find this simple solution. I hope it helps you, too! :)

blocks|key|860732|text|这里有很多好的答案，但我只想补充一件事。有时，您希望将ScrollView滚动到布局的特定视图，而不是完整滚动到顶部或底部。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|860733|一个简单的例子:在注册表单中，如果用户在表单的编辑文本未填写时点击“注册”按钮，您希望滚动到该特定的编辑文本，以告诉用户他必须填写该字段。|860734|在这种情况下，您可以这样做：|860735|scrollView.post(new+Runnable()+{+
++++++++public+void+run()+{+
+++++++++++++scrollView.scrollTo(0,+editText.getBottom());
++++++++}+
});|code-block|syntax|javascript|860736|或者，如果您想要平滑滚动而不是即时滚动：|860737|scrollView.post(new+Runnable()+{+
++++++++++++public+void+run()+{+
+++++++++++++++++scrollView.smoothScrollTo(0,+editText.getBottom());
++++++++++++}+
++++});|860738|显然，您可以使用任何类型的视图，而不是编辑文本。请注意，getBottom()根据其父布局返回视图的坐标，因此ScrollView中使用的所有视图都应该只有一个父布局(例如，线性布局)。|860739|如果在ScrollView的子级中有多个父级，我找到的唯一解决方案是在父视图上调用requestChildFocus：|860740|editText.getParent().requestChildFocus(editText,+editText);|860741|但在这种情况下，你不能有一个平滑的滚动。|860742|我希望这个答案可以帮助有同样问题的人。|860743|entityMap^0|0|0|0|0|0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|10|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|11|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|12|8|@]|9|@]|A|$]]|$1|F|3|G|5|H|7|13|8|@]|9|@]|A|$I|J]]|$1|K|3|L|5|6|7|14|8|@]|9|@]|A|$]]|$1|M|3|N|5|H|7|15|8|@]|9|@]|A|$I|J]]|$1|O|3|P|5|6|7|16|8|@]|9|@]|A|$]]|$1|Q|3|R|5|6|7|17|8|@]|9|@]|A|$]]|$1|S|3|T|5|H|7|18|8|@]|9|@]|A|$I|J]]|$1|U|3|V|5|6|7|19|8|@]|9|@]|A|$]]|$1|W|3|X|5|6|7|1A|8|@]|9|@]|A|$]]|$1|Y|3|-4|5|6|7|1B|8|@]|9|@]|A|$]]]|Z|$]]

There are a lot of good answers here, but I only want to add one thing. It sometimes happens that you want to scroll your ScrollView to a specific view of the layout, instead of a full scroll to the top or the bottom.

A simple example: in a registration form, if the user tap the "Signup" button when a edit text of the form is not filled, you want to scroll to that specific edit text to tell the user that he must fill that field.

In that case, you can do something like that:

<pre><code>scrollView.post(new Runnable() { 
 public void run() { 
 scrollView.scrollTo(0, editText.getBottom());
 } 
});
</code></pre>

or, if you want a smooth scroll instead of an instant scroll:

<pre><code>scrollView.post(new Runnable() { 
 public void run() { 
 scrollView.smoothScrollTo(0, editText.getBottom());
 } 
 });
</code></pre>

Obviously you can use any type of view instead of Edit Text. Note that getBottom() returns the coordinates of the view based on its parent layout, so all the views used inside the ScrollView should have only a parent (for example a Linear Layout).

If you have multiple parents inside the child of the ScrollView, the only solution i've found is to call requestChildFocus on the parent view:

<pre><code>editText.getParent().requestChildFocus(editText, editText);
</code></pre>

but in this case you cannot have a smooth scroll.

I hope this answer can help someone with the same problem.

 @Override

Is there any way to scroll a <code>ScrollView</code> programmatically to a certain position?

I have created dynamic <code>TableLayout</code> which is placed in a <code>ScrollView</code>. So I want that on a specific action (like clicking a Button, etc.) the particular row should scroll automatically to a top position.

Is it possible?

Can I scroll a ScrollView programmatically in Android?

有没有办法以编程方式将ScrollView滚动到某个位置？我已经创建了放在ScrollView中的动态TableLayout。所以我想在一个特定的动作上(比如点击一个按钮，等等)特定的行应自动滚动到顶部位置。有可能吗？

问我可以在Android中以编程方式滚动ScrollView吗？
