i have a program i want to do which has 5 grids of 5x5 squares which need to be clickable, plus 10-20 control buttons, problem is that after about 80 onclick listeners i start to get what i think are memory errors, i was thinking about radio buttons to control my grid, any better way than the 125 buttons? in vb6 button arrays were easy...

I have used GridView for 2-dim grid of Buttons. My problem is, that a user may "navigate" through this grid's cells -- with use of arrow keys it is possible to move yellow rectangle and by pressing enter select cell (rectangle becomes orange for a moment). Everything is behind buttons which are placed in cells of grid. How to disable possibility to select and navigate cells of grid? I would like to still use grid view but have the same possibility to navigate (change focus) among buttons (not cells in which buttons are placed) at it is possible when I place buttons in cells of TableView (not GridView).
View 4 Replies View RelatedI currently have code that creates rows in a table that hold a string in column 1 with a RadioButton in column 2. There can be a variable number of these rows. That all works just great, but I want to add them to a RadioGroup so only one button can be toggled at a time. When I tried to add the dynamic RadioButton to the RadioGroup AFTER I added it to the table row, I got an error saying that the child (the RadioButton) already had a parent. I agree, it does have one, the TableRow.
can you have radio buttons tied to a radio group inside of a row or, should I just code my own toggle mechanism and avoid RadioGroup all together? I mean, I could code the onClick to unclick all other radio buttons, but I would rather not do this if I can use the build in RadioGroup.
<ScrollView
android:id="@+id/ScrollViewModifyGroups"
android:layout_width="fill_parent"
android:layout_height="fill_parent".............
I have multiple radio buttons which I want to layout using a table but also include them in a single radio group. I have the following xml layout:
<RadioGroup android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:id="@+id/Group1">
<TableLayout android:id="@+id/RadioButtons"
android:layout_width="wrap_content".........
But unfortunately the radio buttons inside the table seem to ignore the fact that they're inside of the RadioGroup tags and because of this you can select more than one radio button at the time. I noticed that by removing the table and just having the radio buttons it works just fine. How can I overcome this? Would it be as simple as declaring the radio group inside of the table instead of outside?
I have a similar query to the one posted here. I create a grid consisting of a variable number of buttons, at runtime (in a TableLayout), and would like to find the index of the button pressed. The actual Button objects are currently stored in an array, although I'm not sure if that is really necessary. I tried to write the ClickListener using something along the lines of code...
but this just always returns -1. Is it possible to get the id (or some other reference to the button pressed) without predefining the buttons in xml?
The solution in the other post describes cycling through the whole array of Buttons and comparing ids. Is there a more elegant way to do this?
I currently have code that creates rows in a table that hold a string in column 1 with a RadioButton in column 2. There can be a variable number of these rows so I cannot just create it in the layout xml as radio1, radio2, etc. My code displays the table with the string and RadioButton pairs just great, but I want to add them to a RadioGroup so only one button can be toggled at a time.

Is it possible to build a GridView object in XML with 3 columns and 4 rows of Image buttons? It doesn't seem to have similar containment relationship like LinearLayout or RelativeLayout viewgroups.
I want to do this entirely in an xml layout file. When I put ImageButton xml tags inside a GridView xml body, The layout panel in eclipse is throwing an exception: UnsupportedOperationException:addView(View, LayoutParams) is not supported in AdapterView.
I'm looking for a way to enable, disable and return the status of a radio device, which may be the cell phone, bluetooth or wifi. To check if the radio is supported on device.
View 3 Replies View RelatedI have a need to create a control similar to UITabBar in iPhone, which is to be present on every activity of my application. UITabBar essentially is a battery of buttons exhibiting a TAB like behavior: every button maps to an activity. I have two solutions for this: 1. In the layout XML for every activity, I insert a <LinearLayout><Button/><Button/><Button/></LinearLayout> element. And then have a common listener class that will handle the button clicks. So, every activity will have an instance of this listener. 2. To create a custom Widget extending LinearLayout class, put all the buttons as its static members and let it handle the button clicks. Include this custom control in every screen. I am not sure which approach to follow.

So I want to make an ADT to test in that uses an 800x480 display, but whenever I set the size I get no buttons. The Streak has a Home, Menu and Back button aswell as volume/mute and power, and I need to use some of them for my application.
I'm not worried about the tilting messing up my application. Not yet, anyway. Just need the test environment the right size and with buttons.

View 2 Replies View RelatedI turned on my Droid this morning to listen to MSNBC and I heard the last 5 minutes of Keith Obermann (5:55 am est) and then all of my news and talk channels disappeared! Channels like CNN, C-SPAN, MSNBC and NPR are all gone from my favorites and the channel line-up. There is nothing in the "News and Public Radio" category.
Has anyone else noticed this? I'm thinking this must be a temporary glitch but I would hate to lose all of these channels. If you have the Sirius/ XM radio app, would you please check this on your Droid?
Depends on the size and gauge of the wire of your headphones. Also depends on the position of the wires. FM radio is a little picky, but works fine- depending on the points mentioned. Old & wrong: The FM radio on the Inc must be the weakest radio in a phone, evah! Just tried it today and picks up half the channels my Ngage and N900 pick up well. A lot of channels barely come in, or are static filled. I thought Steely Dan said "FM has no static at all"? Makes the CDMA radio seem not that bad, in comparison I know- at LEAST it has a radio. Must be set to suppa powwa savva mode
View 32 Replies View RelatedI just got my Droid but I frequently use Pandora and Last.FM on my computer at work. Last.FM - Seems like the service has a better list of artists than Pandora so i switched to it on my PC recently. On Android the service is the same but as an app it tends to be open in the background all the time and suffers from not being able to pause (like the PC version). The scrobbling could be nice for some users and it links to the android player. Sound Quality seems excellent, best of the three so far. Pandora - Haven't gotten to use it too much because it takes so long to load my station. Sound Quality seemed fine with my limited use.
Slacker Radio - Has the most music options of the three and seems likes the best application. It has plenty of options like keeping the screen from freezing while plugged in and on wifi without having to change your phone settings. Had to stop listening from poor sound quality though! Sound Quality started ok but a bassy boom and click started appearing after a few songs, forced to switch to Last.FM.
Does anyone have an idea when we will see one of these apps for android?
