I have different elements in my layout: Buttons, RadioButtons, EditText, a ListView and I have made a RelativeLayout that is clickable and starts a new intent. Everything works ok except that I can't select that element with the trackball. Is there any way to achieve this?

I coded an AppWidget the user can add to his homescreen. There are a bunch of images (ImageView) in it that perform different actions like starting Activities on click (realised with PendingIntents). To make it easier to navigate through the AppWidget I'd like to use the trackball (as it works with the SearchWidget or FacebookWidget) but I just can't make it work. Here's my layout code for the AppWidget...
So I want to be able to navigate through a bunch of these "Spots" that are all relativeLayouts. How can I make that work out? I'd be really happy about every hint or idea!
I have a TextView which is inside a LinearLayout which is in the child position of an ExpandableListView. Without assigning a color state selector to the text view, the following behavior is observed:Text unselected - text paints as white Text selected - text paints as black.If I add a color state selector with a call to text.setTextColor(R.color.textcolorstatelist) then the following behavior is observed:Text unselected - text paints as black Text selected - text paints as black.I tried two versions of textcolorstatelist.xml and both produced the results above.
View 9 Replies View RelatedI have a LinearLayout with two views in it, an ImageView and a TextView. The ImageView resource is actually pulled from an xml selector in res/drawable so that it shows one of two drawables, call them selected.png and unselected.png. When I call LinearLayout.setSelect(false) the unselected.png drawable appears and the text is drawn in white. When I call LinearLayout.setSelect(true) the selected.png drawable appears and the text is drawn in black. How can I change this behavior of the TextView so that it always draws in white?
View 4 Replies View RelatedI'm trying to access the textviews (for starters, eventually replace with imageviews etc) which are stored in the tablerows in the code below.
The line beginning 'log.d' was the part I was working on, trying to get it to print out the contents of the 2nd text view in the first row, but I can only get as far as selecting the tablerow using "getChildAt(i)".
Trying "getChildAt(0).getChildAt(1)" doesn't select the textview as I would have expected it to; says that it's a View and as such, doesn't have this method - though unless I'm mistaken, aren't tablerows ViewGroups, which do have this method? code...
I'm trying to implement a Select All menu item for a ListView in a ListViewActivity. The relevant parts of my ListViewActivity: public class MyListViewActivity extends ListActivity browsed around stackoverflow.com and the google; the above is something that should work. But it isn't. setSelection(i) appears to be the method I want to call on ListView but it's not working as advertised. What am I doing wrong? Is this even possible on Android in code?
View 2 Replies View RelatedNew to Android and starting to work on file mgmt. I set up some subfolders on my SD card for pictures. I have been moving pictures from one folder to another, but I can only move one at a time. Is there a way to select multiple picture files and move them to another folder (like "Select All" with Windows)? This is the sequence I've been following: Use the Edit Icon in the Astro taskbar, select Move, then going to the directory folder I want to move them, and hit Paste. Moving one file at a time is taking for ever.

I have a ListView that contains an Image on the left of two vertically-oriented TextViews using a RelativeLayout. When both TextViews have text it looks fine. Sometimes the TextView on the bottom won't have any text, and the problem is that the entire layout is several pixels above where it should be because it still reserves that space for text when there isn't any making the entire list have annoying blank gaps. I remember seeing an example of where someone made the layout not reserve the space, but I can't remember how he did it.

I have a TextView that I created in the main.xml. In my app.java I am dynamically positioning that TextView based on where the user taps the screen. The problem I am having is that when I call myTextView.setPadding(100,100,0,0), it moves the actual Text of the TextView, but does not move the Colored Background of the TextView.

I am making an application like Facebook. In m.facebook.com, when I open it I see they do one thing specailly.
(Alice) is writing on (BackStreetBoy1010938920) wall
Because the width of Mobile screen is small so the real message like tha
(Alice) is writing on (BackStreet
Boy10101009393) wall
I guess they use TextView for (BackStreetBoy1010938920) but I can't do like this.

View 4 Replies View RelatedI have tried all day to capture a trackball event in a View. Basically I want to use the trackball to move a Sprite in a 2D game left and right. The onTouchEvent works perfectly well in the View to move the Sprite with my finger but it would be nicer and cleaner to use the trackball.Can anyone provide me with a simple example that uses the trackball to move something in a View in a 2D type game world (not a menu or UI type of example)? Or can someone explain what I'm not doing. Thanks so much for any help you can give me.
View 3 Replies View RelatedI want to move an image around the screen according to the trackball movement. I am able to capture the movements using the onTrackballEvent method. But this is being called for very small float values (I believe for each rotation?) of the trackball.Now as X and Y positions of views should be integers when specifying with LayoutParams, it makes no sense to move the view with every rotation. Instead I want to move the view only after the user stops rotating the trackball.Is there any method by which we can get whether the user stopped using the trackball or not?

View 6 Replies View RelatedI'm trying to figure out how to continuously update the coordinates of the trackball. Right now, I just want to write the values on change to TextViews to understand how it works.
I've been looking at the onTrackballEvent. Right now, I assume that each event passed as an argument to it should be seen as a complete event, that is from the start of the trackball movement to the end. Is this correct? Because if so, the values of x and y will be the same during the execution of the onTrackballEvent body. If this would NOT be the case, I could just use a timer and update the values at a regular interval..
So either I have to somehow interrupt the onTrackballEvent call and write the values, repeatedly over and over again while it is still moving, which seems weird, or...well this is pretty much were my Google search skills and Android knowledge comes to a halt.
Is there a way I can make the LED or trackball pulse while my application is running and the screen is on? The same behavior as when a phone call is received for instance?

View 1 Replies View RelatedI've run into some difficulties with implementing a custom progress dialog. Even though an overlay intercepts touch events the user can still operate the trackball and click elements that are supposed to be disabled.
Is there any way around this?
I've run into an issue where performing a lot of touch events seem to block the move events from the trackball. Anyone else run into this issues? I can't use the Thread.sleep() fix because that will obviously stop all input, so I'm hoping someone has been able to throttle the touch command without effecting the move ones.
