Android :: Views And Their Child Views - How To Avoid The Ugly - Boxes - When Child Views In A View Has Another Color Than Background

Jan 6, 2010

I have a simple ListView and on that ListView I have placed a number of custom defined Views. The CustomView has ImageView and two TextViews.

The CustomView also has a "stateful drawable" as background, so that the background image (a 9-patch) changes if you press the Row in the ListView. When pressing the Row, the background image changes to a Red-ish thing.

The problem is that when the background changes from the default greyish, all the Views in the CustomView (ImageView and TextViews) still have their greyish background and thus creates very ugly greay boxes on top of the now redish background.

What is the best way to solve that problem? I hoped that such things were handled automatically (as it is done in for example .NET), but I was wrong it seems.

Android :: Getting Cell Signal Strength For Current Cell Vs Neighboring Cells

Jan 6, 2010

I'm writing an android application that collects cell signal strengths.I am having trouble getting the "current" cell signal strength, but I don't have any problem getting the "neighboring" cell signal strengths.To get the current cell signal strength, I created a PhoneStateListener and implemented the onSignalStrengthChanged callback.It works, but not very well.It seems like the signal strength hardly ever changes, and resolution jumps to only a few numbers.I would accept the answer that the resolution of the signal strength hardware is coarse, but when I use the TelephonyManager's getNeighboringCellInfo() method, it works much better.The signal strength readings from neighboring cells change frequently, and they have much better resolution.So, how can I get the current cell signal strength in the same way that I am getting the neighboring cell strengths?It seems odd to me that the functionality of the neighboring cells is better than the current cell.

Android :: How Can Update The All The Views Inside A TabHost When Pressing On A ContextMenu Item From Within One Of The Views

Nov 16, 2010

I am implementing a music player application in Android. My play list selection screen is implemented as a tab selector widget which contains a ListActivity inside each of the tabs: Artist, Albums, Songs.
I want to update the ListView in each of the ListActivity when I delete an item from any of the lists.

i.e. When I long press an item in the Artists list a context menu is drawn with "Delete Artist"
And it should delete all the songs from this artist in the Songs ListView, delete all the albums by this artist in the Albums ListView, and finally delete the entry for the artist in the Artist ListView.

Each of the ListActivity has its own fillData() method, which updates the ListView when the button in the context menu is pressed.

How can I call the fillData() method of the Albums ListActivity after I update the ListView inside of the Artists ListActivity?

Android :: How To Make Use Of Views Defined In Layout XML File As Template To Create Views Programmatic Way

Android :: Switching Views With RadioButton And Saving Views In Bundle

Mar 6, 2010

I have the following XML code:.................

The idea is to change the views, whenever I press one of the radio buttons. When I press a button the first time everything works out fine, but the second time I press a button, I get an IllegalStateException, and I can't quite see why I'm getting this.

Also, the Activity seems to set all my global variables to null, which is why I have to create them every time I switch from portrait to landscape or vice versa. So I would like to know if there is a way I can save my views in the Bundle, or any other way in which I can permanently save my views, so I don't have to add or create them every time, I flip the phone. And whenever I flip the phone, it seems that it rereads the main XML file, causing the RadioGroup to be set to 2D even if the 3D button is checked. This is because I've said the 2D button to be checked from when the app is first created, but I would like to also save the state of that RadioGroup.

Android :: Neighboring Cell Signal Strengths Better Than Those For Current Cell Signal Strength?

I'm writing an android application that collects cell signal strengths.

It seems odd to me that the functionality of the neighboring cells is better than the current cell. Am I missing something here?I would also like to directly call a method from the telephony manager to get current cell strength, as opposed to a listener, if possible. If anyone knows how, please let me know.

Android :: GetHeight() Of TextView In TableRow

Nov 27, 2009

I have an Activity in which I have a TableLayout. I fill the table with TableRows in which I display TextViews. Imagine this as a classical table with text content. After the loop is finished I want to read all the heights in pixels of all the TextView in this table. I do this with getHeight(). The problem I have now is that ALL the values are 0 (zero) pixels. Even though I have text in the TextViews. The odd thing about this is, if I read the height of the exact same TextViews in an OnClickListener () then I do get the real height of the elements. Why is that so? I mean, nothing has changed in the height of those elements in the time between filling the table and firing the OnClickListener(). I really need to be able to get the height of the TextViews right after I filled the table. To get the heights upon a click is too late already for what I want to do.

Android :: Using Tablerow - TextView In Tablelayout?

Apr 21, 2010

I am using Tablerow+TextView to make a simple view for blog posts and their replies. In each TableRow I put a TextView in. Now I have two issues:

The text which is longer than the screen won't automatically wrap up to be multi-line. Is it by design of TableRow? I've already set tr_content.setSingleLine(false); [update]

This has been addressed, I think I should change Fill_parent to be Wrap_content in

CODE:............

The Table won't scroll like ListView. My rows are more than the screen size. I expect the table could be scrolled down for viewing just like ListView. Is that possible?

Here is my code:

Android :: Do Root Views Of An Activity In Android Have Any Prior Knowledge Of The Child Views That Will Be Loaded Into Them

Jan 25, 2010

Is there any way to query a root view of an activity for all of its child views even before the root view or its children have been inflated? I guess what I'm looking for is whether a view knows ahead of time what children it will have before it gets inflated, and can I get that list in some way. Bizarre I realize, but I think it will help me with some unconventional automation testing I'm working on. I haven't found anything in the API like this.

Android :: GestureOverlayView Causes Strange TableRow Blending

Now when I take the GestureOverlayView out of the code and leave everything else as-is, my table looks fine - the rows are separate and not on top of each other..........

Android :: How To Make Children Of Selectable TableRow

Sep 23, 2010

I'm making a image gallery with infinite vertical and horizontal scrolling. I put images inside a ListView to make a column, and put the ListViews inside a TableRow. However, it seems that child views of TableRow is not selectable and as a result I can't select the images in my ListView (easily). Is there a way to pass the events down to child views of TableRow so they can be selectable?

Android :: Unable To Select Children (textview) Of TableRow Programmatically / Fix It?

Nov 2, 2010

I'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...

Android :: How To High Low Network Over Cell?

Apr 16, 2009

So my app works well in the emulator in various run configurations and on the device when the device is connected to WiFi. But when I switch off the WiFi on the device, the code that goes out to the network takes forever and then times out (i.e. doesn't return any data). Other people have reported this as well. I also notice that no data is going out or coming in when I look at the little up and down arrows on the 3G icon in the status bar on the G1. I am assuming that the Java code I am using should work for both types of connections, right? I mean, do I need to account for the fact that cell data network is very slow with high latencies i.e. pre-cache my data etc?
