Android :: Strange ListView Scrolling - Rows Turn Light Green
Aug 16, 2010
I have a ListView in my app that has a background image. All of the rows are a semi transparent white (#35FFFFFF). Whenever I scroll the list, the rows turn a light green that obscures the background image until I stop scrolling (usually--sort of unpredictable). Sometimes it flickers between the background image/color and the green. And yes, I have set the cache color hint to #00000000. Any advice about this would be appreciated.
ListView xml:
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="7px"
android:cacheColorHint="#00000000"..............

I've been trawling the internet looking for an answer for several hours, but I can't seem to find anyone who has been able to solve this. I've got a listview which uses enter code herea custom adapter. A row looks like this. The list is filled by an array. Everything works great. Now, I want the ImageView and the ToggleButton to react to clicks, so I implement the OnClickListener in my adapter, put the items position in each view's tag, and then I set their onclicklistener to this. Works great, except now I can't use the onListItemClick for starting an activity for the item! OK, I say, I just make the relativelayout holding the text in the middle there use the same onclicklistener. Works great. Everything is clickable, and life is good.
EXCEPT! Now, when I scroll the list, I cannot "continue" the scroll by just flinging again. This causes the scrolling to stop, and I have to fling once more to get it going again. It seems the onclick-thingy causes the fling-motion to be interpreted as a tap or something (it does not trigger the logic within onClick).
I know that this is possible by just going to the phone list on my HTC Hero, which has exactly the kind of layout and behaviour I want from my app. This app even seems to have the onItemClickListener working. So how can I make sure the list keeps scrolling, and still be able to click the togglebutton, listitem and the imageview? I've been stuck on this all day, and it's giving me a headache

I was wondering how I could turn off the blinking green light on my phone every time I get a text. If I don't clear my notifications of the new text(s) right away, the blinking light kills my battery. I do want to keep the notification on my drop down bar, I just want the blinking light to stop. Is there anyway to do this? I know I can take off the blinking light and drop down bar notification, but I don't want both gone, only the blinking light.

My wife has been having a very strange problem with her Eris lately. She uses her phone as her alarm and when it goes off in the morning and she picks it up to snooze or dismiss the options simply won't be on the screen, it will be her default home screen. The alarm is still going off though so she touches the Sense clock widget to turn off the alarm manually but as soon as she touches the widget the screen starts to scroll to the left and will continue to do so for a few moments and will eventually stop. She only seems to have this auto-scrolling problem when dealing with her alarm going off. Any suggestions?

Does anyone know how long your led light notification blinks for missed calls and text messages etc.I thought is was to blink until you checked the missed call or message.Mine is going off after 5 to 8 minutes without going into the phone and checking the missed call or text.Is this normal?

There must be a way to do this. How can you tell a ListView that has a header to not scroll it when the user scrolls the contents? I want it to stay in a "stuck" position so that the user can always see what column the content applies to.

i want to implement listview with uses different xml layouts for rows depending on underlying item. A non optimal solution will be int getView method just to inflate every time a new view depending on the item from the adapter. Is there a better way to do this?

is it possible to let my ListView show 2 different rows? On the picture you can see at the top something like a "teaser", the other rows are normal ListView. The screenshot is from the iPod. With their framework it is possible to show 2 different row styles. I badly need this on Android... Otherwise I would use a tabel design. But adding rows dynamically would be such an overhead instead of using ListView SimpleAdapter addItem...

I want to make a listview that has different rows (layouts). I will load the data from a webservice and it can be 2 or more layouts i have to generate then. I am creating a social network app and want to show a stream of the users activity. So when he made a comment, make a new friend, this all has to come in the same list.. I load 1 XML file with multiple different child objects (comment, friend) so i can see which layout i have to use........

I saw the Android app "Mobisle Notes Free" implement a really cool ListView, where a row gets moved to the bottom if its checkbox is checked. It's not just a simple refresh, but an actual animation where you see the row travel to the bottom. Does anyone know how to implement this?

i am quite new to android and i was wondering how i could go about adding a listview with different images and text. What i am trying to achieve is a listview with four rows which have a different Icon? I don't know how to set that up using the xml layout provided. should i build this using different multiple linear layout or is there a better way to go about it?.. All the examples i have seen all seem to be using one particular Icon and no much detail of the xml layout.

I have 2 ways of displaying ListView data. I have a class for each type of row. I do not create the rows in an xml layout. (Each row is derived from View and does custom drawing). When I switch from 1 type of row to another how do I get the ListView to layout properly with the correct row heights, and refresh? Is View.forceLayout() on the right track?

1) Is it possible to use another battery from another htc device? Any other device have a stronger battery you can use? 2) when the green light is on, it means it is fully charged right? however when i go to the desktop app it shows you the percentage of charge, it is only ever in the 90's% when the green light comes on. something wrong with my battery? it still carries on charging but the green light comes on so early.

I have a Cursor that returns rows I use with a SimpleCursorAdapter to populate a ListView. I would like to filter some of the rows so they don't get displayed in my ListView. I use the data from the rows elsewhere in my Activity so I don't want to change my SQL to filter them with a WHERE clause. What is the best way to keep a row from being displaying in my ListView? Ideally I would check a column in my row and then only add rows to the ListView that satisfy a condition.

I use this code in my getView:
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null) {
LayoutInflater vi = (LayoutInflater)getSystemService
(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.listrow, null);
}
Order o = items.get(position);
if (o != null) {
TextView tt = (TextView) v.findViewById(R.id.toptext);
ImageView thumb = (ImageView) v.findViewById(R.id.icon);
if(o.getOrderDrawable()!=null){
thumb.setImageDrawable(o.getOrderDrawable());
}
else{
tt.setText(o.getOrderTitle());
}
}
return v;}
The problem is when scrolling; sometimes the correct image shows, but sometimes when scrolling back/forward, the images shows randomly and that is not associated with the row. The images are downloaded from the web.

So, basically I have a custom View that contains a ListView with a custom Adapter that has the ability to read in information from the network (dumbed down HTML) and display it on a row by row basis. All of this works, but I need the text that is read in to be parsed as HTML which contains links that can be tapped on and launched in browser. I managed to do this by:
text.setText(Html.fromHtml(textBuffer), TextView.BufferType.SPANNABLE);
text.setMovementMethod(LinkMovementMethod.getInstance());
Works great, any <a href=""></a> links in the text are displayed as links and can be tapped. This is a side effect of now making it so the rest of the rows in the ListView cannot be tapped (or tapped and held). Basically, all the rows are non-selectable now. Is there any way to achieve both of what I need?

The row of my listview has 3 texts. What I want to do is to align all the rows texts vertically. I tried that using the TableLayout view for the row, and I've set the width for the first and third cell's as a constant. I'm not very happy using constants because of the porting issues. Is it possible to align these texts without in another way? Here is the layout...

Anyone else notice that the green indicator light is blinking in a different spot? Don't think it's a big deal, maybe it's from the update. I really only noticed it b/c there's a cutout for the light on my Zagg skin and this new light placement is not in the cutout.
