Android :: Adding Numbers And Displaying Answer In Two Activities?
Sep 2, 2010
Just learning and thought this would be neat to learn. Basically getting the value from editText1 and editText2, then by pressing an add button, be able to show the result answer on a second activity. I know this is probably very easy, but I wanted to learn more about how I can do simple math practice while learning the language. Adding two numbers from editText in first activity and displaying the answer on a second activity?

I am able to launch contact application from the following way. I am also able to show Name and only one Phone number. My problem is 1- How can I show multiple phone number [like Home, Mobile, Work etc] when I am launching contact application. How can I do that? 2- In Contact application there is one option *More*, which is an expandable list. When I click that it open with other many fields like Notes, Website, Nicknam etc. How can I fill those fields while launching the Contact application? Code...

I have a LinearLayout defined in XML that I want to use repeatedly to display elements of a list. The XML-layout looks like this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@drawable/background"
android:paddingBottom="5px">
<TextView
android:id="@+id/destination"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textSize="22dp"
android:text="@string/test_destination"
android:paddingLeft="5px"/>
<TextView
android:id="@+id/date"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textSize="15dp"
android:text="@string/test_date"
android:paddingLeft="5px"/>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/info"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:paddingLeft="5px"
android:paddingTop="10px" >
I gather information about certain events from a webpage, and then I want to display all events in a list using the above layout for each event. My current approach is to have a LinearLayout as parent and then adding each event as a row.
Problem number one is to add the layout to each event (the number of events is varying). I.e., I want to dynamically inflate this layout for each event. I also don't want the text to be hard coded into the layout (as above) but added at runtime. I don't know how to do this. I have tried something like the following without any success.
LinearLayout eventView = (LinearLayout) findViewById(R.layout.event);
parentView.addView(eventView);
Problem number two is then to add these layouts to the parent view group and display it on the screen. When I try to do this using parent.addView(child), the program crashes at runtime and I can't figure out why.
It's kind of hard to describe the specific problem, since I'm new to GUI-programming on Android and I'm sort of programming by trial and error right now. Anyway, if you are able to help me with some of the problems it would be greatly appreciated. Linus
EDIT:
The problem now is adding text dynamically to the TextViews. I try this:
TextView dest = (TextView) findViewById(R.id.destination);dest.setText("myText");
only to discover that dest is null. Any ideas why and how to fix this?
EDIT 2:
I have narrowed the problem even more, but I really don't understand its nature. This is the trouble-method: Code...
it somehow works (even though the events are displayed in reverse order). Anyone knows what's going on here?

I have Nexus 4 and ever since I bought it, it saves all phone numbers with spaces between the digits (like +44 555 555 5555 etc.)
How to have these numbers with no spaces in between? I tried changing the language to English US, English UK and English Autsralia... etc. but no luck with that!!
It really bothers me as well as so many people out there as I found many people complaining about the same issue:

I have an ActivityGroup containing three embedded Activities (A, B and C). Sometimes I need to "destroy" A and B to start another one, D, and when D is finished, A and B are re-created. Is it possible? If so, how can I do it?

My Eris has always had issues with knowing who is who in my recent calls, texts and in google voice from time to time. I reformatted all the contacts to +1-555-555-5555 format(something that someone on a google forum suggested) but it still doesn't fix the problem. For instance- A friend named Steve called me. I see incoming call from and it knows who steve is and says "Incoming call from Steve". I called him back, clicking on the exact icon in my missed calls that says his name and it says I called 5551231234 (unknown). This happens in my messages as well, and it is starting to drive me crazy. I will get a message from 5551231234 and it will only list the number and not the name, so I have no idea who is texting me. For some reason my phone is incapable of putting it together to figure out that the number it lists as unknown is already a contact in my contacts. I have to always call people back to figure out who it is or send a text asking who they are.

Today I set up a group on my desire so that I can send a group text or email to the parents of the kids football team that I help to run. It seem that it uses the primary number that's selected in the persons contact info. Some parents have given me both their mobile numbers and sometimes two email addresses so I want to include them all in the same group. Does anyone know how I can do this? On my previous blackberry curve 8900 I could select multiple numbers/email addresses from the same contact to go into the group.

int tocols[] = new int[] {android.R.id.text1, android.R.id.text2};
Cursor c = managedQuery(People.CONTENT_URI, columns, null, null, null);
SimpleCursorAdapter sca = new SimpleCursorAdapter(this,
android.R.layout.simple_list_item_2, c, columns, tocols);
setListAdapter(sca);

New Droid 2 owner here. This forum has taught me so much about my new phone. My problem: When I look up "Me" in Contacts (not in Edit mode) it does not display my phone numbers. It displays all my other contact information except the phone numbers When I go into Edit mode they are there (Home, Work, & Mobile). They are also listed in my G mail contacts. Is there any way for the "Me" contact to display my own phone numbers?

It would be interesting to know if the number of people buying apps is growing as fast as the number developing them. Has anyone seen data about either?

I want to add a contact just to my phone and not to my gmail account.Whenever I start to add a contact (phone, 208544.menu, +contact, create new contact,) the next thing it forces me to do is to choose an account to create the new contact under and it lists my 3 gmail accounts.I have no option to just put it on the phone.Any ideas here?We do the same thing on the Incredible but it gives us the gmail account and the phone to choose from but not on the Motorola.

Occasionally, a couple times a month, my Moto Droid will ring, the phone app pops up... but there are no sliders to answer. It rings and rings, and about the time that it's going to go to VM, the sliders will finally appear. Sometimes I miss the call, other times I can get it. More often, it will ring, and either the phone app doesn't show up at all, or it shows up but then disappears (phone goes black). I have to manually unlock the phone (I have gesture security), and then I can usually get to it. if the phone has gone black, I fumble around with hitting the power button, shaking it (I have screebl), touching the screen and finally the gesture screen comes up. Kinda feels like multitasking/processor priority issues they haven't elegantly worked out yet, but I wanted to see if this sounded familiar. Any apps that make it so that when the phone rings, processor priority is handed to the phone? I don't see the app killing other apps, just downgrading their priority to (nearly) zero until you're done with your call, or even just until you have answered your call. The flaw is just in the answering part. When a call comes in, I want my *phone* to be super responsive to that *phone* part of things, y'know?

I want to answer a phone call. I found the intent android.intent.action.ANSWER but it seems that the only effect that I obtain is an ActivityNotFoundException. Why? Is it a deprecated intent? How can I achieve answer? I have also heard about the "telnet technique". What is that?

I know this has been asked before, but at this time the answer of the post is not true.
http://stackoverflow.com/questions/2610587/how-to-programmatically-answer-a-call
Vringo and other apps does answer the phone by pressing a button on their app, so there must be a way to do it.
Anyone has a suggestion?

Now I know there will be a thread or 2 about this at the moment but I thought I would double check being a newbie and all. If someone leaves a bad comment, or a competitor leaves a bad comment (to help their sales), so on or so far, is there no way to either delete it or at least answer the comment back? HUGE oversight if not and frustrating What have other developers done to overcome this problem?

I am looking for a lockscreen replacement that most importantly gives the option to answer calls without using the slidey swipey thingy. Maybe just a answer call button. I have tried goto - that was cool, but still had the swipe to answer. Also i tried screen suite, but that thing didn't replace the home lock screen for some reason. Can you sugget any others you might be using or know of?

I don't know how to programming it?
Hint1. Use acceptCall() function. I find the API documentation from location http://www.androidjavadoc.com/m5-rc15/android/telephony/Phone.html#ac.... But SDK haven't this function.
Hint2. Simulate key press to press the green button. But I have no idea about simulate key.
If you have any other idea about answering auto call then you can help me also.

Is there any easy way to answer a call? I just got my first android (4.2) phone and find it a complicated procedure to answer calls.
When I get an incoming call I get a white phone symbol which I have to press and hold to get the red and green phone symbols to appear and to answer a call the timing has to be exact as if I release the white phone symbol before I have started the slide to answer it fails and I find it about impossible to reject a call with this method.
I thought there might be some setting to alter this like the lock screen but can't find anything.

I am using the following code to do an automatic answer of a call, but it doesn't seem to be working.
Intent answercall = new Intent(Intent.ACTION_ANSWER); startActivity(answercall);
I get the call state of "ringing," but it never answers.

I have a very hard time with the slide to answer feature. It frequently takes me 3-5 tries to answer a call. I would much rather be able to touch to answer. I do realize that there's a slim chance of answering calls while in my pocket, but I'd rather that then fight with the phone. Does anyone know of an application for this? I've searched various forums and there are no current threads regarding this.
