I have the following problem, and I cannot figure out how to eve try solving it (or whether there is a way):
My problem
I have SrollView
, containing to EditText
input fields. One is a single line, below is a multiline. Everything's fine and works as expected, up until I put too much stuff into the multiline EditText
. When I fast scroll the view, the scrolling skips and stutters, very obviously, the whole effect is rather disturbing. tried on a Galaxy S3 with a custom AOSP ROM, and Note 4 with official 5.1.1, no difference at all.
I would expect a very heavy EditText
makes it difficult to smoothly redraw on a fling, but this starts happening with relatively short text (approx 4-5 screen-pages long).
Edit: This also seems to happen on a simple scroll, when I do as much as touch it and move it a few lines (scrolling is not near to being smooth, that is)
The setup
I have reduced the widgets to the bare minimum, even removed padding, only the problem does not improve. From the Java code I also removed anything (any styling, or typeface, anything that affects the widgets at all), still no improvement.
If this is of any significance, the ScrollView
in question is inside a fragment, that is one of two pages of a ViewPager
. There is nothing else on this fragment ATM.
Here's the XML (as you will see, it's as base as possible):
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:singleLine="true"/>
<EditText
android:layout_width="match_parent"
android:layout_height="match_parent"
android:isScrollContainer="false"
android:inputType="textMultiLine"/>
</LinearLayout>
</ScrollView>
What I tried
Any advice I found regards only ListView
s, and some attributes like android:smoothScrollbar
, which have no effect here (I tried them all).
For the record, I did try out of frustration all of the below ( I know most of these has not much to do with ScrollView
s, but I'm becoming hopeless here):
android:hardwareAccelerated="true"
android:fastScrollEnabled="true"
android:scrollingCache="true"
android:smoothScrollbar="true"
and also tried setting from the Java code things like
.setSmoothScrollingEnabled(true);
.fling(3500);
still no luck.
Question recap
Is there any way to make a simple widget like this scroll smoothly at all?
Thanks for your time if you've read through and even more if you answer. :)
