Android :: EditText Wrapped In ScrollView
Jul 21, 2010
I have an issue with EditText when it's wrapped in ScrollView.
Please see the following layout setup:
CODE:............
There's nothing special about this layout. I just want the EditText inside ScrollView to be scrollable when I entered more than 5 lines of text.
I tested this layout with both Eclair and Froyo and Eclair seemed working fine, but Froyo didn't really work at all. Was there any change on ScrollView?
ScrollView api says that I can put EditText(or TextView) inside of ScrollView to have this kind of functionality, so I guess that I did make a mistake or missed something important.

The problem I am having seems to be that if I have a view (e.g. myButton) inside a RelativeLayout set to alignParentBottom - (as per the code below) - and then wrap the RelativeLayout with a scrollview (necessary so the content will be viewable on smaller screens or when orientation changes to landscape) - then, when the parent bottom is NOT visible (for example when changed to landscape orientation) myButton is displayed at the TOP of the page - NOT the bottom.How can you align a view to the bottom of the screen and have it remain at the bottom even if the bottom is below the scroll?

Our app (WordPress for Android) uses a ScrollView for the new blog post view. The issue is that if a user writes a lengthy blog post in the EditText, they are unable to scroll inside of the EditText because the ScrollView seems to be taking over the scrolling action, even when you are in the EditText.
Here's the layout XML (the EditText in question is @id/content):

I have a Dialog implemented with scrollview and a multiline edittext item in the scrollview. I see that I can use the scrollbar in the edittext as the scrollview will take over it. Can they co-exist and work together?

Our app (WordPress for Android) uses a scrollview for the new post view, where a user enters in their new blog post. There's quite a few fields on this view, including a large EditText for the post content field.
It appears that when an EditText is in a ScrollView, the ScrollView takes over the scrolling action, so the user can't scroll within the EditText area if they are writing a large post. What can be done so that scrolling will work both within the EditText and the ScrollView?
Here is the layout xml for this view, The EditText that needs the scrolling is @id/content:

I am trying to make a non-editable EditText that is placed in a ScrollView and scrolling is controlled programmatically (when a left/right fling is detected).
Here's my simple layout:
CODE:..........
And here is my simple program:
CODE:.............
So, to explain it simply, I have two custom simplegesture classes that I attached to the EditText and the ScrollView. For the EditText, I'm trying to detect a left/right fling and when detected, I'm scrolling the it up 1 page up/down. The custom simplegesture attached to the ScrollView is to disable finger scrolling.
Here's a screen shot after a right fling was done: http://img830.imageshack.us/i/textcut.png/
I kinda works right now but I have two questions:
How do I control the scroll so that lines won't get "cut-off" (please refer to the picture above where the first line on the screen is a bit "cuf-off"). Why when I scroll the page up/down programmatically, the EditText is auto select-all (please refer to the picture above where the whole screen turns orange after scrolling)? Why when I changed MyGestureDetector to detect fling on the Y-axis (vertical fling) and programmatically scroll the EditText, it doesnt' work? It wouldn't work even if I made the change in ScrollGestureDetector too. Does it have something to do with the behaviour of the ScrollView?

I must be overlooking something real simple here, but i think i'm trying to do something fairly basic.. Simply retain the scrollbar position of a ScrollView on orientation change...
Here is the code for my onSaveInstanceState and onRestoreInstanceState.. sView is the container for the ScrollView layout. Within my scrollview is a linearlayout with a lot of textviews.
CODE:............
If I set a Toast with the values of sViewX and sViewY on the Restore, the values are kept and correct.
I just tried to do a sView.scrollTo(0,150); in my onCreate.. just to see if that would open the activity at 150px down, and it didn't. I think my issue has to do with the .scrollTo method.

I want some of the goodies in a ListView, like being able to use a ListAdapter, and item selection, etc, but I don't want the ScrollView portion of it. I want to implement that part myself, in a different way (why or how I do this isn't really the point of this question, so please don't ask "why"). Is there a way to have a ListView that's not in a ScrollView or has the scrolling disabled?

I believe I know the basics and have successfully published a nice graphical game (Tairu). I know about inflating an xml layout and instantiating views that work.
For my current project, I really just want something similar to the Windows 'DrawText' function where it will draw a bit of a text inside an arbitrary rectangle of the surface, and do word wrap within that rectangles boundaries. That's what I really WANT, but I can't find any form of drawText that will wrap.
So, while that's what I WANT, I can accept the thought of programmatically instantiating a TextView (which wraps beautifully). But I still need to be able to provide the rectangle, which is highly dynamic. (which is why I want to call a form of drawText inside of my onDraw method). In this particular case, I have something which is static to a particular view instance (I mean, the View becomes visible, the position is set, and does not change after that. but the text position is dependent on game state and cannot be pre-determined inside an XML layout). So in this one case, I could afford the expense of runtime recalculation of the layout when the view is displayed.
OK, fine. So I do something like this:
CODE:......
Pretend you didn't see 'AbsoluteLayout' there, I am desperate and have tried all possible layout classes
main_frame is defined in my main XML layout (it is the outermost layout, fills the parent, and, as I said, I've tried all the offered layouts)
With this code, the textView appears, but along the top of the layout, and not using the width I provided either.
Adding, out of desperation.
CODE:.......
makes no difference. In fact, so far, NOTHING has made any difference. So I thought, ok, while this seems like a useful thing to be able to do, I can accept if it can't. I accept that it is impossible to provide dimensions in advance and that you have to override the measure and layout callbacks then requestLayout and in your overrides, force the final layout for the TextView.
Of course, that is completely unacceptable for my FIRST desire (a drawText that wraps to a rectangle, called from onDraw as needed). But the point is I feel something like that OUGHT to work, and it doesn't, so clearly this is MY fault.
Getting back to what I WANT, I guess I can do it myself by repeated calls to measure text and parsing the string for spaces until I get the N characters which fit on the first line, then repeat for additional lines, calling a normal drawText for each line (and using textMetrics to determine the vertical offset to the next line.)
But why wouldn't that method already exist? I promise not to fill the screen with a zillion calls, and/or to cache pre-rendered text on some bitmap somewhere if antialiased drawText is too expensive to repeat frequently.

Adding an image on EditText works fine. However, copying an image is another problem. When I insert an image on EditText by using ImageSpan it shows correctly, but I copy inserted image, EditText shows me only 'obj'.

I want an EditText to look like TextView but still behave like EditText. I've tried applying TextView style to my EditText in my layout.xml file, like this:
CODE:............
But I get an error within xml editor: "Error: No resource found that matches the given name (at 'style' with value '@android:style/ Widget_TextView')." It is strange because @android:style/ Widget_TextView definitively exists - I double checked it in code via android.R.style.Widget_TextView. Another strange thing is that I don't get android:style offered in the xml editor while typing? There is android:id, android:text and everything else.. but not android:style?
I consider the hard way (making EditText look like TextView) to be: extending EditText and overriding it's onDraw method.

Every time I put a TextView before an EditText element in a LinearLayout, the EditText does not show. When I don't, it does.
I've narrowed the problem down to the TextView's layout_width attribute. If I give it "wrap_content", it works, but doesn't "block" down, and it appears on the same line as the EditText.

CODE:............
I have this at the top of my application. When the application starts, the EditText is orange highlighted and has a cursor in it; when the EditText is tapped, the soft keyboard pops up. The user uses it to type into the EditText.
However, when they click the Button, my onClick method fires and does everything it's supposed to, however the soft keyboard stays on screen and the EditText is still highlighted with its cursor.
I also have, at the top of the Button onclick: findViewById(R.id.name).clearFocus();
In spite of this, the EditText does not seem to clear its focus. How do I make the button actually act as if it is submitting the form?
Also, I do not transition to a different Activity on the click of the Button. I suppose that is the typical case, and probably the reason why they don't bother hiding the keyboard. However I want to keep the search box and button at the top of the screen, so I just dynamically fill and add views to the screen when the Button is pressed. How can I achieve my desired behavior?

I've got a ScrollView containing a vertical LinearLayout.
The LinearLayout contains several items, including a ListView.
The problem is that I can't seem to get the ListView to be fully expanded. It is being compressed to fit everything on the screen, and forcing me to scroll through just the list. I would prefer to be able to scroll the entire layout, including the ListView.
I've played with the layout parameters a lot, but can't seem to get anything to work.
Also, I'm going to put this in another thread, but thought I'd ask here as well. Is there any way to force a separator at the top of a ListView?

I am trying to display a screen filled with data fetched from a server. The data, if it were HTML, would look something like the following (try to visualize =) ):
CODE:..............
So I naively tried to put a ListView in a ScrollView. Not only did it not work, but I've since read all about why it is bad by the likes of such luminaries as Hackborn and Guy (it nullifies the optimizations, etc).
Problem is, the half dozen places that said NOT to do it didn't recommend what I SHOULD do instead, excepting one post by Romain Guy specifying footer or header use (not suitable in my example, right?). In other words, it seems like people want to mix a list of items in among other text data, getting the benefits of a ListAdapter, but this isn't addressed anywhere that I can find.
So, what is The Right Way to implement my example above? I'm a step away from trying to add TextViews inside a for loop, which just doesn't sit right in my gut.

I show articles in WebView and would like to add some additional information, e.g. publishing date, author etc., into the same ScrollView above the original content. So that it usually doesn't take up space, but the user can just scroll back when the information is needed.
Did any of you do something like that in a sane way?
I thought I can put my stuff into the same ScrollView that WebView uses, but when looking at it with hierarchyviewer I can't see any children, it's probably native.

I'm making sort of a book app. I have the text displayed as a textview in a scrollview:
CODE:.....
I then have
CODE:...............
And implemented the required following to catch a left fling or right fling. And
CODE:.......
This works fine if the text inside the textview is small (ie. there is no scroll bar as it all fits within the view). But as soon as the text requires scrolling, the gesture is no longer picked up by the detector. onFling is never called.
I have read that it is because scrollview handles its own gestueres? If so what is the easiest way to maintain the ability to scroll up and down the text, and also be able to detect flinging left or right and invoking nextChapter() and previousChapter() respectively?

I have two ScrollView inside of each of two HorizontalScrollView of a TableRow. When I touch drag one of ScrollView, another ScrollView must scroll as much. For instance, if I have a list of name on left ScrollView and corresponding phone numbers in right ScrollView, scrolling one ScrollView should not destroy the original bounding between the names and phone numbers. Can it be implemented by onTouchEvent? If so, how should I implement this(on both or one of the ScrollView)?

I want to draw a chart and I'm using a scrollview to do so. my scrollview holds the chart view. What I've observed is that the scrollview's onDraw calls the onDraw of my chart view. Now I draw the entire chart on the canvas when the onDraw of chart view is called. Also scrollview's onDraw is called everytime I scroll the view. So I end up drawing the entire chart multiple times. Is there any better way to achieve what this

I have a little problem with a ScrollView.I have a layout for an activity which is made with a ScrollView. This scrollview contains two ListViews.<?xml version="1.0" encoding="utf-8"?>
<ListView android:id="@+id/accountsListView"
android:layout_width="fill_parent"
android:layout_height="wrap_content" android:scrollbars="none" />
<ListView android:id="@+id/cardsListView"
android:layout_width="fill_parent"
android:layout_height="wrap_content" android:scrollbars="none" />
</LinearLayout>In onCreate method of my activity I compute ListViews height according there contents.During execution, on activity launch, ScrollView is already scrolled a bit.So I tried, at the end of onCreate to call method scrollTo(0, 0), but it does not change anything.
