Is it somehow possible that instead of:
Button btnNextWord = (Button) this.findViewById(R.id.btnNextWord);
Eclipse automatically generates for me something like:
Button btnNextWord = this.btnNextWord;
or
Button btnNextWord = R.id.getBtnNextWord(this);?

first of all: yes, I read all the other threads on this topic. And not only those from this site... (you see, i'm a little frustrated) Most of them come with the advice to use "android:id" instead of just "id" in the xml file. I did. From others, i learned, that View.findViewById works different than Activity.findViewById. I handled that, too.
in my location_layout.xml i use
<FrameLayout .... >
<some.package.MyCustomView ... />
<LinearLayout ... >
<TextView ...
android:id="@+id/txtLat" />.................
I just heard this on another forum, that if you need to change something you typed you have to go to landscape and use the dpad. You supposedly cannot use the touch screen to go back. Can this be true?

Let's say I was typing for a bit and I noticed that I mis typed something. If I want to put my cursor where the mis typed letter is, it is not always the easiest thing to do. I noticed on my friends iphone if he were to put the cursor near the letter and hold his finger there a zoomed in window would pop up and alow him to move the cursor to the location he wants to put it.
Is there any app that can do this on the droid?
Can anyone recommend a good battery monitor-typed app? It can be a widget or app, but I'd like to have some sort of visual representation of how much battery is left (like a %). Doesn't have to be in notification area (unless I can hide the stock one). All the ones I search in the market just don't look like they are worth anything, and if I pay for one, I want it to be worth it. I'm monitoring my battery usage. I installed one and it told me 30% but the stock battery bar was full. It was then uninstalled.
View 8 Replies View RelatedOne of the things I missed of my Palm Pre was being able to type a text and it will save what I typed even if I completely exit out of the program.
On the EVO when I typed the message and didn't send, I would lose the message when I hit the Home button to do something else. When I came back, the message was gone. I know if I hit the "back" button, it will save as drafts, but thats not what i'm talking about.
However, this morning I typed a message and hit the home button (In my mind I knew it would be gone, but it wasn't that important of a message) but when I went back to the text message, it took me back to the same exact message with my text saved.
What did I do differently? And how can I keep this feature?
I am requesting information regarding writing an app that would respond to user input from the keyboard. Basically, I want to turn certain words into symbols when they are typed. So, if 'brb' was typed, then I would put up "Be Right Back" or something similar onto the screen.

1. How to run an app as a thread
2. How to have an app monitor what is typed in as input from the keyboard
2a. Is this limited to text / email / any app?

View 1 Replies View RelatedI am learning how to program on Android phone. However I am unsure how to make my application work for the different screen sizes and resolutions.
I read the tutorial on the android site and still unsure how to do it.
First I know there are different files so could make a layout for each of the sizes but my problem is most of the screen needs to be dynamically created so there would not be much to put in these files.
So I am not sure how to android to re size dynamic controls based on the screen size.
I have also read it is bad practice to make controls in anything but the xml file as it separates view logic and programming logic. However they never talk about if you need to make these controls dynamically what you should do.
So is there some other way to do it that is considered good practice?

To your question: It's dynamic because
the buttons in my example grow and
shrink depending on one of the 3
possibles sizes, because they use
scaled pixel (You probably know that
you don't have to deal with screen
sizes itself). So a scaled pixel
compared to a real a pixel has a size
of 0.75px, 1.0px or 1.5px. Android
automatically and dynamically adjusts
it to the actual size. So you don't
have to care about this in your code.
So if I use scaled pixels then I don't have to worry about different screen sizes?
At the moment I don't know an example
except in games where you have to deal
with "real" pixel. But if you want use
it, multiply it with the value of the
current density. This is your "ratio".
I don't have the example with the ball
anymore but I have another which uses
the same technics. You can run it on
different screen sizes and you will
see that the buttons will always fit
into the layout. You could use the
same technics for your intents. In
this example you can scroll with the
"Scrn" buttons from one view to
another of 4 views. (At the moment
they all have a black background so
you don't see that they are different
views). The "Enter" button exits the
test. It's an Eclipse project. You can
download
So if I want to deal with ratio then I use real pixels and not scaled pixels? What advantage does this give me?
will scaled pixels work with changing from portrait to landscape( ie will it fill up the new found space)?
Finally should I make the controls now through code or is there another way? As I said I am getting data from a webservice that must look like this
checkbox label label
It can be one record or 10,000 records I don't know so these have to be appended to something that is like a window panel( the controls in there get a scroll bar).
I am able to play a video using VideoView in combination with MediaController.
