I have an Android scrollview with a white background. The fading edge is a white translucent gradient. I would like to change it be black instead of white. I have a ListView in the same project with a white background that has a black fading edge by default, but I can't find where (if anywhere) that was set.

I have a couple of list views, one uses TextViews laid out with xml, the other uses a custom class derived from View. The default halloween color scheme is pretty ugly. How can I change the background and selection colors for the list elements. Ideally, I'd like to be able to do this in code not xml, to handle the custom view.

I'm trying to create a game lobby for a project, and I'd like the game's status text to be a different color: red for an "[IN PROGRESS]" game and green for a game that's "[Waiting for x players]". The ListView will be populated with data, and each ListView item will have a game ID and then immediately to the right of that the game's status.
Right now I'm essentially using the Hello ListView code to create my ListView.
(In constructor)
CODE:...........
Then, I have a refresh button that obtains data from our database. It will get two Strings, one for the ID of the game, and the other for the status of the game. If the game status is 0, then it's still waiting for players. If the game status is 1, then the game has started. So, I create a gameItem to add to the gameList:
CODE:.............
This is where I'm stuck. I don't really understand how I can alter the specific TextView when I create the gameItem or when I add that to the gameList. There isn't a way I can see of accessing the TextView's properties. I see how the text of the view is set (through the mapping of the strings to "line1" and "line2", but I don't know how to change any of the properties.
I wanted to see if I could change the top/bottom wrap fading effect seen on most long scrolling components. In this case I would like to change the color from black to whatever color I desire on a ListView.

I have 2 questions regarding a ListView in Android:
How can I get the color of the listview's focused row ? I tried to use the ListView.getSelector() method, which according to its documentation should give me what I'm looking for, but it's giving me a Drawable object which I don't know how to retrieve the color from (if possible...).
How can I set the color of the listview's focused row ? Here I tried to use the setSelector() method on the listview, passing it a ColorDrawable object, but the result of doing it is that the whole background of the list view is painted in that color... and this is not what I wanted of course...

View 3 Replies View RelatedHow can I change background color of ListView items on a pair-item basis. When I use android:backgroundColor in the ListView item layout I can achieve this, however the list selector is no longer visible. I can make the selector visible again by setting drawSelectorOnTop to true but then the selector overlays the whole item.
Any ideas how to change those background colors and keep the selector?
I would rather not change the selector itself.

View 2 Replies View RelatedHow can I color code individual rows in a ListView exactly like it is done in the native MESSAGING app? I do NOT want to simply do alternating rows, but I want to copy the format used in the MESSAGING app, where message rows have a different background color based on the username of the message. FYI: I am currently extending SimpleAdapter and overriding getView(int position, View convertView, ViewGroup parent) . In this method I am trying to calculate setting the background color based on the position as compared to a list of 'positions to highlight' that I am maintaining each time I update the list, but so far this is only working the first time the list is updated. In class that overrides SimpleAdapter:
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = super.getView(position, convertView, parent);
if(highlightPositions.contains(new Integer(position))){
view.setBackgroundColor(highlightColor);
}
else{
view.setBackgroundColor(normalColor);
}
return view;}
I have a listview with custom rows and that extends SimpleAdapter.
Each row consist of two linear layouts : 1st having two textviews of which one is hidden in horizontal orientation, second having two textviews in horizontal orientation.
Now depending on the value in hidden textview , I want to setcolor for the remaining items for the row.
To put it as simple:
each listview item has some custom colors the value of which comes from the hidden field.
I have done this by overriding getview() for the simpleadapter and returning view for each, but this makes list very slow to render (and that I think is obvious as so much of work for each view before showing it).
Can I do this in some more efficient way ? like making views and then add up to list instead of using xml layout maybe one solution OR any other?
I'm trying to create a particular effect where I have a bunch of particles on the screen which leave trails that slowly fade. I was hoping that I could simply use glClear with a small alpha value to do this but that doesn't seem to be working.My second idea was to draw a black face on the front of the screen but this doesn't seem to be giving me the right effect, the particles are faded but the background doesn't really fade. My next idea is to render to a texture and fade that texture but that's a lot of extra work and I'm not sure if it will solve my problem. Can anyone think of a way to do this? Am I missing something?I'm having trouble finding information about rendering to a texture on android. If anyone has some links to articles that would be great.
