Android : Can I Use Layer-list - Shape Elements To Draw A Horizontal Rule
Nov 10, 2010
I want to set the background of a Relative or LinearLayout to a custom drawable. I want the shape to draw two horizontal lines across the bottom, leaving the central part transparent (empty). The following draws the horizontal lines centered vertically, where as i need them to be aligned to the bottom of the shape. (If you add a rectangle as an item you can see the shape expands to the dimenstions of the parent, but the lines are still centrally aligned). Code...

I want to have a elmenent with a 2 color border outline. I can do a single color outline using the element, but this only allows me to draw a single line. I tried using 2 elements within my but that didnt work either. Is there a way to either draw a shape within a shape or draw 2 lines around my shape (which has rounded corners btw).

I've got a standard RelativeLayout laying out my Buttons and TextAreas. What I want to do now is be able to draw various sparks, flying cows etc. at arbitrary places on the screen on top of the whole thing. What's the best way to do this? Should I override onDraw() on the containing View and draw after calling super.onDraw()? Or is there some better way of drawing a layer on top?

I want to draw a bitmap into a shape (in this case an isosceles trapezoid); not clipped, but with the bitmap transformed to fit the shape. For example, if the height of the left side is greater than that of the right side then I want the bitmap evenly transformed in height from left to right to match the height difference. The only method I can find to do this is drawBitmapMesh, however this produces some strange results. I have searched extensively and can find no concrete information on drawBitmapMesh.
To demonstrate the example, I have a bitmap which contains an even grid of vertical and horizontal lines. I use bitmap mesh with the code shown below. However, the horizontal lines of the grid do not evenly merge downwards from the top and upwards from the bottom towards the target. Rather, horizontal lines to the left of the line dissecting the top-left to bottom-right diagonal of the shape slant downwards to the left, lines to the right of the same diagonal slant downwards to the right. I also note that that the top line of the bitmap increases slightly in height from left before descending again to the right.
Perhaps drawBitmapMesh is not the method I should be using, or perhaps I am using it incorrectly.

When I have a ListActivity and an Adapter how does Android handle a list with 200 elements.
Does it try to load all of them directly how does it wait till the user scrolls and then renders those elements?
Do I have to worry with performance when a list is too long?

I need an advice. What is the best way to implement in android a list of such UI elements (see the ref)A list contains a lot of such elements (about 30-40). I'm using now relative layout and 4 text fields and I think it isn't a good way.I think it's too heavy (full list will contain: 30 relative layouts and 30*5 = 150 text fields).

I have a list view which contains some 20 odd items along with a check box. Now when iam trying to delete an item by checking its checkbox,Now if I have six elements in this ViewList, which are visible on the emulator, then the same code just works fine. Problem arises when the list is long and it starts scrolling and some element are not visible.

I have a ListView with an adapter extending BaseAdapter.I create a view (from a LinearLayout and I put some items ont it depending on some parameters. I have a textview, with a drawable and sometime another textview next to the drawable in this horizontal linearlayout. For some reason, this command doesn't seems to work. So when my textview doesn't fill the full width of the list, I can only click on the part of the elements with the widget on it. I have try playing a lot with the layout and I can't get this to work. The parameters seems to be ignore all together. Only hack that would work I found was to set a big minimum width on my linearlayout but I don't think that's the best solution.

I've a ListView where every element in the list contains a TextView and two different Buttons.I found a solution as described in my answer below. Now I can click/tap the button via the touch screen. However, I can't manually select it with the trackball. It always selects the whole list item and from there goes directly to the next list item ignoring the buttons, even though I set .setFocusable(true) and setClickable (true) for the buttons in getView().This causes that no list item is selectable at all any more. But it didn't help in making the nested buttons selectable.

I am rendering a ListView inside a dialog. The ListView elements are very simple TextView objects. The problem: whatever I do, they never take the full width in the list view, which has the side effect that the list view selector only covers the actual text, not the whole list entry (i.o.w., if the text of the entry is much smaller than the width of the listview/dialog, then only a tiny portion of the list element is highlighted when focusing it).

Ok so I know many are having battery issues. You, like me, probably have more battery life than you think. This is because the application layer of the phone is not receiving the hardware layer's data correctly (hold talk button, end call button, and middle button upon starting up your turned-off phone, this boots in test mode which shows you hardware layer battery power, aka the correct battery life estimate). It's causing another problem because some applications can't be run when the phone THINKS it's about to die.

I'm attempting to create a list view that shows clickable items that wrap horizontally much like the To/From/CC/BCC fields in OS X and the iPhone's Mail programs or like the TO field in Facebook's messages (really like most mail programs). My questions are: 1. Is there a way to do this with a ListView? Everything I've seen and experimented with is either horizontal scrolling or vertically stacking, but not horizontal wrapping. If there's a way, would you point me in the right direction as far as first steps to take to implement it? 2. Is anyone aware of an existing app with available source that has a view like this that I could look at as an example? The Google Mail/SMS apps just have single strings that are not clickable for those fields.

I'm attempting to create a list view in Android that shows clickable items that wrap horizontally much like the "To" field in the OS X and iPhone's Mail programs. They have a horizontal list of names that wrap vertically and each name is a separate object, the list is not just a single string. My questions are: Is there a way to do this with a ListView or some other type of AdapterView? Everything I've seen and experimented with is either horizontal scrolling or vertically stacking, but not horizontal wrapping. Are you aware of an existing app with available source that has a view like this that I could look at as an example? The Google Mail/SMS apps just has a single string in the too field that isn't clickable.

It seems like the best way to create a horizontal scrolling list of images is to use the Gallery widget. I need to display sidebar text with each image.The examples I have seen showing how to use the Gallery widget only show images. Is it possible to display a list of images+text descriptions in a Gallery, and if it is, does anyone have an example of how to do this?

I don't know exactly how to explain this problem, but I'll try. I have a ListView with several items. Each item has inside a TextView and two ImageView. I want the ImageView change when I click on them, and I want to open a context menu when I press for a long time into the ListView item.For the ImageView, everything works properly. For the whole item, I can show the context menu after a long press, but my problem is that the ImageView changes as well when I am pressing the TextView, for example.I hope you understand my problem. I think that all the children of a view are affected by an event in the parent, but I am not sure.

Meebo, the free IM app is now available for download in the andriod market place.
I've been using www.meebo.com to IM on AIM, MSN, and GTalk with 1 logon and without any download (at work mostly heh) for a while now and I have nothing but praise for it.
Now they're created an app that does the same thing for the G1.
If you'd going to try it out, I'd recommend setting up your accounts on the computer/website first (really easy) that way it's ready to go when you DL the app for the phone.
I'm using it, it works, check it out if you need an all-in-one IM client.

I read this quote in one of the webpages: If you are writing a large application, consider dividing it into a suite of applications and services. Smaller applications load faster and use fewer resources. Making a suite of applications, content providers, and services makes your code more open to incorporation into other applications as described the "Use and be used" tip. Is this true? What is the thumb rule for the size of app?

Do any of the current email apps out there now support rules for incoming messages and different alert tones? That's why I'm a slave to my blackberry, I can set certain work emails as priority 1, and assign a different tone to those from certain addresses. If there's an app for Android that does this, I'll pay dearly to be able to have that work. Anyone made such a thing yet?

I have a custom view on which I need to call a method from my activity after the view has been measured in onMeasure. I would like to know exactly when onMeasure is called in the View layout process. It looks like onMeasure is called after my activity´s onCreate, onStart, and onResume. I could override onMeasure and maintain a variable that contains whether the view has been measured or not. However it would be nice to know if there is a rule that relates onMeasure to the activity lifecycle?

I have a GIS layer, that holds information about some areas. It is basically a rating for a specic area. So each shape defines a specific rating. I would like to be able to add this layer to Google Maps and then in my Google Android phone be able to open a little application that just shows that rating based on your current location as a big number on the screen. I am fairly new to Android development, so I don't know the Google Maps API that well yet. I would be very happy for any pointers in the right direction and even happier if anyone could present an example.
