I am trying to figure out how to set priorities on imagebutton.I want to have a layout with a bunch of Icon or buttons that can be selected either by touch, radio, or checked box. As these images are selected they are set on queue to be displayed in order of Precedence.(that is to be pre-determined). The images are displayed once the main action button is touched.

I am trying to to use WiFi API to set priorities to created profiles. I am using the priority field of WifiConfiguration to set this information. I have found out that no matter what priority I set, Android always tries to re-connect to the latest access point that it was connected to. Here is what I do: 1) I create a profile A with a very low priority (0) 2) I create a profile B with high priority (100) 3) I connect to profile A 4) I turn Wi-Fi off 5) I turn Wi-Fi back on 6) In the scan Android sees both A & B 7) Android connects to A, even though its priority is much lower. Does anyone has a work around for this?
View 2 Replies View RelatedI have applied the follwoing selector to all my buttons by specifying it in my theme:
CODE:...............
This works fine. But I want the background of the button to remain "@drawable/my_btn_pressed" when the button is pressed, as if to highlight that this was the last button pressed. Hence, I added the code in my onClick() to set the background resource:
CODE:.............
This also works to highlight the last pressed button with "my_btn_pressed". However after this, my selector properties do not seem to work on the other buttons. Mainly, the state focussed is not distinguishable, at all.
How I can do both, i.e distinguish focussed, pressed and normal states of the button, as well as highlight the last pressed button?
In my app I bring up a context menu on long click in a ListActivity. One of the options "Priority" pops up an AlertDialog with 3 radio button choices. The problem is, it displays an empty dialog box without my 3 choices, or the message that I set. Here is my code...
If I replace the .setSingleChoiceItems with a positive and negative button instead, it displays the buttons and the message as expected. What am I doing wrong in setting up my list of radio buttons? Here is my calling code as well...

View 7 Replies View RelatedWhat does remark "Applications can not normally change to this priority" for some priorities in android.os.Process mean? I can successfully change thread priority to THREAD_PRIORITY_URGENT_DISPLAY or THREAD_PRIORITY_AUDIO (and I can confirm the effect). But I use ADP firmware, maybe on 'normal' G1 this method will throw? Or is it just an documentation glitch? If not, should we absolutely not use these priorities, or we can try, but be prepared for an exception?

I am not able to find out the perfect layout(viewgroup) to place four buttons as shown in the attached image. Basically, i want to place four buttons near the top/left/bottom/right edge of the screen. AbsoluteLayout helped, but it is deprecated (It is also better to avoid AbsoluteLayout as it is not very flexible for orientation changes)
View 2 Replies View RelatedI have touched on this question here, where Christopher gave an answer to this, but I dont really get it so I thought its time to make it a real question, not just a "follow up" =)
As it stands, the application Im writing has 4 different screens:
1. Screen 1 - list of nodes (main screen)
2. Screen 2 - options menu, tableLayout with buttons
3. Screen 3 - navigation
4. Screen 4 - text details on version etc
These screens can be navigated to/from using a "header" View that is placed on top. the header then has 4 different buttons:
+--------------------+
| menu with buttons |
+--------------------+
| |
| |
| |
| C O N T E N T |
| |
| |
| |
+--------------------+
The header is just an XML-file (header.xml) with a few buttons. That header.xml is the included in the Layouts using the include-markup. For example, the main.xml has the line:
<include layout="@layout/header"></include>
The header show up alright, but the question is - what is the correct approach to attach OnClickListeners for the buttons in the header?
Christopher pointed out that you could create an Activity class and do the hooks there, like this:
CODE:............
First, I cant make it work since the method setupHeaderButtons isnt accessible from FirstActivity.
Secondly, is this the right way to go at it?
I want to create three button on the layout. But the default align of the buttons is in a column like: Button1 Button2 Button3 But I want to the three buttons align in a row in order to save space.

View 3 Replies View RelatedI am trying to get my first button to update a display number in my view when clicked. This view will have several buttons and "outputs" displayed. After reading examples and Q's here, I finally put something together that runs, but my first button is still not working;
Some of this appears unnecessary at the moment (ie. Gravity on makeView), but it works! And should work for the 10-20 buttons I want to do misc things with.The key was getting listeners right, and the whole set-up for TextSwitcher was abit awkward...still learning.
I was trying to set up my options menu so that there would be 2 buttons on the 1st and 2nd row and then 1 button on the 3rd row. Here is the code I was trying to use but I'm guessing groupID argument isn't what I thought it was.
menu.add(1, MENU_NAME, 1, "by Name");
menu.add(1, MENU_NUMBER, 2, "by Number");
menu.add(2, MENU_POSITION, 1, "by Position");
menu.add(2, MENU_COLLEGE, 2, "by College");
menu.add(3, MENU_UPDATE, 1, "Update Roster");
Maybe this is solved somehow with the XML Layout but I'm not really good with the layouts ;( So I managed to not get too far that way either.
I'm trying to write some functional tests for my application that include interactions with the UI. As part of the test I'm trying to press a button programmatically. I've both tried TouchUtils.clickView() and Robotium (third party's utility for this task). But buttons don't get pressed. With Robotium, whose sources are simpler to understand, I can track my code until it properly generates ACTION_DOWN and ACTION_UP events. At the same time, I've tried a Robotium sample together with a small sample application, and it works perfectly. So, Robotium works and my Android SDK is ok.it must be something specific of my application. What should I check?

1) touching a button and then pressing down on the trackball to select it, and
2) drawing predefined gestures from Gestures Builder

Then I select starting a new Activity depending on whether the using pressed a button or executed a gesture. However, when I attempt to draw a gesture, it is not picked up. Only pressing the buttons is recognized. The following is my code:

I'm trying to customize my buttons in my view a bit and give them my own look. Whenever I set a picture as a background so that the button looks different though, I seem to lose my cursor. I can use my trackball to go through the items still but when I come to one of my custom buttons the cursor does not show. I have the same problem with some TextViews that I made clickable.
View 1 Replies View RelatedI have a love-hate relationship with my G1, with the inability to remap keys at the top of the list. I've looked high and low for information, going so far as to try to decipher pages like this:http://www.kandroid.org /android_pdk/keymaps_keyboard_input.html and even reading the android platform code on github. I don't see things like page_up and page_down defined in the android keymappings. And I suspect that the original scancodes are being assigned to touch gestures.Since the number keys don't have a third component could an enterprising developer map to the unused caps for missing keys? Not that it would be all that useful at this point but it would give someone a hook to build on. Or if that isn't possible, how about a virtual floating task bar kind of thing (maybe mostly transparent overlay?) that maps gestures like the swipe up/swipe down and more traditional arrows and enter type keys for the trackball? This isn't entirely a nit-picky kind of request. I have a medical condition that in the winter makes my fingertips extremely painful and the trackball hurts. I'm guessing that there weren't many arthritis sufferers on the Android development team, either. You would think that the touch screen should make things easier, not harder. Even my old, old Omnigo and HP100LX had utilities to remap keys, so it seems odd that there isn't some kind of app that could be developed. I think if I had enough time (which I don't) I might be able to eventually puzzle out a crude version of the task bar thing but I'd much rather pay a couple of dollars in the market.
