Android :: How To Scroll To Bottom On Activity Startup?

Jul 22, 2010

I am displaying some data in a ScrollView. On activity startup (method onCreate) I fill the ScrollView with data and want to scroll to the bottom. I tried to use:
getScrollView().fullScroll(ScrollView.FOCUS_DOWN).
This works when I make it as an action on button click but it doesn't work in the onCreate method. Is there any way how to scroll the ScrollView to the bottom on activity startup? That means the view is already scrolled to the bottom when first time displayed.

Android :: Getting Button To Scroll Into View At Bottom

Sep 8, 2010

I am trying to port an existing iPhone application to android. I wish to have a button scroll into view at the bottom of a GridView to enable the user to load more data from the server. Presently, my solution simply fixes a button at the bottom of the screen instead of having it scroll into view.

Here is my layout code:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android
android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" >
<GridView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/grid"
android:layout_width="fill_parent" android:layout_height="wrap_content" android:columnWidth="70dp" android:numColumns="auto_fit" android:verticalSpacing="0dp" android:horizontalSpacing="0dp" android:stretchMode="columnWidth" android:gravity="center" android:background="#000000" />
<Button android:id="@+id/load_more" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:text="Load More" /> </LinearLayout>

Fixing the button at the bottom of the screen won't work because I plan on placing an ad at the bottom. Can anyone either explain conceptually how to get a load more button to scroll into view, or point me to some sample code, OR tell me why this is not idiomatic to Android and what other UI convention it uses to load more data in a GridView?

Android :: Can I Programmatically Set A Wallpaper To Not Scroll

Oct 1, 2010

I am writing an app that allows a user to set the phone's wallpaper from a list of pictures.
By default it scrolls across the multiple home screens. I want the wallpaper on the home screen to be a static non-scrolling image.

What can I do programmatically to achieve this? Is this even possible?

I am using wallpaperManager.setResource(...); to set the wallpaper.

Tried wallpaperManager.setWallpaperOffsetSteps(0,0); -- did not solve it.

Android :: Scroll View Alawys Scrolling To Bottom

May 14, 2010

I defined a scrollview with a texteedit in my layout:
<ScrollView android:fillViewport="true"
android:layout_marginBottom="50dip"
android:id="@+id/start_scroller"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:fadingEdge="none">
<TextView
android:id="@+id/text"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
</TextView>
</ScrollView>
I add text to this ScrollView with the following method:public void writeToLogView(String textMsg) {
if (text.getText().equals("")) {
text.append(textMsg);
} else {
text.append("
" + textMsg);
scroller.scrollBy(0, 1000000); As you can see i append the text and try to scroll to the bottom of the ScrollView. Unfortunately this doesn't worked correctly. It scrolls down, but not always, and not always to the bottom. Any hints?

Android :: How To Programmatically Scroll Droid WebView

Feb 10, 2010

I'm trying to programmatically scroll a WebView to the location of a particular element in the DOM tree. But so far I haven't been able to get the WebView to respond to scroll requests. I've tried calling JavaScript that uses window.scrollTo(...), but the WebView doesn't respond. On the Java side, I've tried calling the WebView.flingScroll(...) method. WebView will respond to flingScroll, but what I need is a scrollTo(...) capability. Any ideas?

Android :: Show Scroll View With Button Anchored Bottom Of Screen?

Mar 18, 2010

I'm trying to show a ScrollView with a button anchored to bottom of screen. This is coded programmatically (without using XML layout for now). The trouble is when the ScrollView has many items (requiring scrolling), it prevents the button at the bottom from showing. The bottom button is sort of pushed off the screen. Look at the code below. I have a TODO which mentions a workaround to specify the exact pixel height of the ScrollView, but this is not a good solution. If you change the for loop to add only 2 buttons, then the bottom button will show. So how do I make the ScrollView show a scrolling list, with the bottom button in view, and without specifying an exact size of the ScrollView? I've seen some discussions here:

http://groups.google.com/group/android-developers/browse_thread/threa http: //groups. google.com /group/ android-developers/browse_thread/threa But I don't know how to apply these to my situation.package com.test.ScrollViewTest; import android.app.Activity; import android.os.Bundle; import android. view. Gravity ; import android.view. ViewGroup. MarginLayoutParams; import android.widget.Button; import android. widget.ImageView; import android .widget.LinearLayout; import android.widget.RelativeLayout; import android.widget.ScrollView; import android.widget.TextView; public class MyScrollViewTest extends Activity @Override public void onCreate(Bundle savedInstanceState) super. onCreate (savedInstanceState); LinearLayout ll = new LinearLayout(this); // the main layout of the screen ll.setOrientation (LinearLayout.VERTICAL); TextView tv1 = new TextView(this); tv1.setText("First line of text"); TextView tv2 = new TextView(this); tv2.setText("Second line of text"); ll.addView(tv1); ll.addView(tv2); ScrollView sv = new ScrollView(this);// You can only add one child (usually a layout) to a scrollview, // otherwise you get exception: "ScrollView can host only one direct child" LinearLayout ll2 = new LinearLayout(this); ll2.setOrientation(LinearLayout.VERTICAL); * TODO: PROBLEM HERE: You cannot use WRAP_CONTENT for height, because * the layout below the scrollView will not show (it's sort of pushed * off the screen - even if a margin is specified). * An alternate value of 300 works OK (remove the bottom margin too).* But this is only suitable for screen size 320x480 in portrait mode.LinearLayout.LayoutParams params Linear = new LinearLayout.LayoutParams( LinearLayout. Layout Params.FILL_PARENT, Linear Layout.LayoutParams.WRAP_CONTENT /*300*/); Add 50 pixel margin to bottom of scrollview (this margin doesn't scroll) paramsLinear.bottomMargin = 50;sv.addView(ll2); // Add some stuff to scrollView to test its depth // (it should leave a margin at bottom of screen) for (int i = 1; i < 10; i++) { TextView textView = new TextView(this) ;textView.setText ("Text View " + i); linearLayout.LayoutParams p = new LinearLayout .LayoutParams (Linear Layout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);

ll2.addView (textView, p); button buttonView = new Button(this); buttonView. setText ("Button " + i);ll2.addView(buttonView, p); ll.addView(sv, paramsLinear); RelativeLayout rl = new RelativeLayout(this); RelativeLayout.LayoutParams paramsRelative = new lative Layout. LayoutParams( RelativeLayout.LayoutParams.FILL_PARENT, RelativeLayout .Layout Params .WRAP_CONTENT); // Make the button anchored to the bottom of the screen.// But this doesn't work when the ScrollView has a scrolling list of items. Why? params Relative .addRule(RelativeLayout.ALIGN_PARENT_BOTTOM); rl.setLayout Params (params Relative) ;

Motorola Droid :: Quick Scroll To Bottom Bug Or Feature?

Nov 12, 2009

I assume that I am not the only Droid's owner who has this weird experience with the device: sometimes when I touch on a list (e.g., Apps listed on Market) or a web-page. The list or page will rapidly scroll all the way to the bottom of the list or page. Although I experience this at least a couple times every day, I am unable to reproduce this phenomenon at will.Does anyone know what cause this? Is it a bug?

Android : Scroll Up Motion Windows Move Up - When Using A Touch

Oct 18, 2010

I'd like to get your suggestion for best option to implement the following interface on android 2.2.

1. Folders (or folder windows displayed as pictures) are assembled or places as a deck of cards on screen 2. when using a touch (scroll up motion) each folder windows move up (scroll up) at a tilted angle and gradually it gets straighten in vertical direction when reaches at the center . The other folder windows are linked as a chain so if you scroll up again the next folder window will take the center position and so on until the last one. This can be scroll up or down.

Apparently, it seem it can be done with GridView or Gallery Widget to start instead working for new widget. if you have experience doing such interface , suggest me for better option?

When in the emulator they work as expected, you touch the edittext and the screen scrolls up so you can see the content. However when i try it on my droid inc the edittext is covered by the keyboard.

Android :: Adding View To Bottom Of Layout Inside Scroll View

Mar 10, 2010

So my layout looks basically like this:
<ScrollView>
<RelativeLayout>
<BunchOfViews/>
<ImageView android:layout_alignParentBottom="true"/>
</RelativeLayout>
</ScrollView>
I have the ScrollView so all of the layout always is visible no matter the height of the screen. The problem is that on a very high screen, I still want my imageview to be at the bottom. However, a child of a ScrollView dont seem to have a defined bottom. The View is placed at the top of the layout. How can I solve this problem in a neat way?

Android : Get Scroll Position In A List Activity?

Mar 23, 2009

I'm trying to get the scroll position on a ListActivity. Here is what I'm trying to do: I have a list activity that is populated from an XML file. Another thread downloads all pictures so the user can see the list while the thread is still downloading the files.

What I'm trying to do is when the thread finishes getting all pics it reads the listview scroll position, refresh the listview and scroll to that position again.

ListView main = getListView(); <-- not sure if I'm really getting the ListView this way. int scY = main.getScrollY(); Log.d("Scroll", scY + " "); <--- this is printing zero even when at the moment I run this I already scrolled the list. setListAdapter(listadapter); main.scrollTo(0, scY);

Android : Way For Optimizing List View Scroll?

Aug 26, 2010

I have list view with fairly complex list view items consisting of several image views, several text views, progress bars, etc. Depending on the state of the item some of these elements can be show and some are hidden. I understand that listview recycles views. Right now I am dealing with slow listview scrolling especially on lower powered devices. What's the best way to deal with this problem?

I already optimized each list item view as much as I could. Now I am facing with what's the best? Use one single view with many children for all items and hide and show various children depending on the item state. This way I do not inflate each item view as list is being scrolled but need to show and hide constantly various child views.

Another approach is to build item view dynamically each time view is requested in the adapter getView method. In this case I can only add at run time those elements that are truly needed for current item state but this requires inflating item view every time.

Finally the third approach is most extreme is to have one custom view and draw everything myself. This of cause requires a lot of work.

Android :: List View Scrolling Past Top And Bottom

Aug 12, 2010

We're working with a pre-release device running V2.1_update1 We have a ListView in the middle of a screen with the height set to wrap-content. On all other devices, as long as there is room on the screen, this control does not scroll--or if it does scroll, it only scrolls to the limits of the entries in the list. On this new device, there is definitely room for the list so it should not be scrolling at all, but the ListView scrolls and seems to have elastic whitespace above and below (and separator lines above the top item and below the bottom item). Thus, when you drag down, the whole list scrolls down within the limits of the view's bounds (i.e. it clips there) and then when you release the drag, the list springs back up to its normal position. This latter behavior makes it seem like there is deliberate code that has been put in for this--but we certainly didn't do that. What could cause this? Is there a setting that has defaulted one way on this device that defaults opposite on other devices?

Android :: List Item Background Is Changing On Scroll

Mar 10, 2010

I have a background color applied to a ListView but everytime the list is scrolled the background color changes back to the system default (black). When the scrolling stops the color goes back to @color/window_background.The style is applied in AndroidManifest.xml:<activity android:name=".event.EventList" android:theme="@style/CKButtons"></activity> and my ListView looks like this: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"

<TextView
android:id="@+id/android:empty"

android:layout_height="fill_parent"
android:text="@string/eventlist_no_items"/>
</LinearLayout>How can I prevent this from happening?
