Android :: How To Update TextView On Button Click With Spinner(s) Values

Jun 14, 2010

I am trying to populate a TextView based on the current selected options in 3 Spinner(s) but cant seem to figure out how to retrieve the selected values from the Spinners to invoke the update function with.
Here is my current code (quite messy but I'm just learning Java,
public class AgeFun extends Activity {
private String[] dayNames;
private String[] yearArray;
private final static int START_YEAR = 1990;
private static TextView textDisp;
private Button calcButton;
private static Spinner spinnerDay, spinnerYear, spinnerMonth;
private static ArrayAdapter<?> monthAdapter, dayAdapter, yearAdapter;
private int year, month, day;
/** Called when the activity is first created. */
@Overridepublic void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
year = 2000;
month = 1;
day = 1;
textDisp = (TextView) findViewById(R.id.textView1);
calcButton = (Button) findViewById(R.id.button);
calcButton.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// Perform action on clicks
AgeFun.updateAge(year, month, day);
// Month spinner
spinnerMonth = (Spinner) findViewById(R.id.spinnerFirst);
monthAdapter = ArrayAdapter.createFromResource(
this, R.array.monthList, android.R.layout.simple_spinner_item);
monthAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinnerMonth.setAdapter(monthAdapter);
// Day spinner
dayNames = new String[31];
for(int i =1; i <= 31; ++i)
{ dayNames[i-1] = Integer.toString(i);
} spinnerDay = (Spinner) findViewById(R.id.spinnerSecond);
dayAdapter = new ArrayAdapter<CharSequence>(this, android.R.layout.simple_spinner_item, dayNames);
spinnerDay.setAdapter(dayAdapter);
// Year spinner
yearArray = new String[40];
for(int i =0; i < 40; ++i)
{ yearArray[i] = Integer.toString(START_YEAR+i);
} spinnerYear = (Spinner) findViewById(R.id.spinnerThird);
yearAdapter = new ArrayAdapter<CharSequence>(this, android.R.layout.simple_spinner_item, yearArray);
spinnerYear.setAdapter(yearAdapter);
updateAge(2000,1,1);
}private static void updateAge(int year, int month, int day) {
Date dob = new GregorianCalendar(year, month, day).getTime();
Date currDate = new Date();
long age = (currDate.getTime() - dob.getTime()) / (1000 * 60 * 60 * 24) / 365;
textDisp.setText("Your are " + Long.toString(age) + " years old");

Android :: Call Spinner's Value - Use Other Values Based On A Spinner's Value

Jan 25, 2010

I have a spinner 'aperture' set up with a list of numbers, and a spinner 'mode' with two options. When a button is pushed I need a calculation to run using various inputs, including the current selection from 'aperture' and a value derived from 'mode'. How do I call the value of a spinner so I can use it in a calculation?

Also, how do I use the spinner 'mode's selection to set this other value before implimenting it in the calculation? To be more specific, if the spinner is set to Small then the value I use in the calculation is 0.015, whereas if Large is selected I need to use 0.028

My other inputs are EditText views, so right now I am set up like this:

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

That is not the actual equation, it is just a test to make sure everything connects properly. How would I call the value of spinner 'aperture' and the Small/Large spinner 'mode'

Android :: Clicking Elements Doesn't Display Correct Values / Point Where It Would Pull Old?

Apr 14, 2010

I apologize if this code looks a bit like a mess (considering the length); I figured I'd just include everything that goes on in my program at the moment.

I'm attempting to create a fairly simple Tic Tac Toe app for Android. I've set up my UI nicely so far so that there are a "grid" of TextViews. As a sort of "debug" right now, I have it so that when one clicks on a TextView, it should display the value of buttonId in a message box. Right now, it displays the correct assigned value for the first element I click, but no matter what I click afterwards, it always just displays the first value buttonID had. I attempted to debug it but couldn't exactly find a point where it would pull the old value (to the best of my knowledge, it reassigned the value).

There's a good possibility I'm missing something small, because this is my first Android project (of any note). Can someone help get different values of buttonId to appear or point out the error in my logic? The code...

Android :: Droid Application Fails And Stops After Clicking A Button / What To Do?

Nov 24, 2010

I started a small android application to learn. I placed an input text and button on the screen. That shows on the emulator. After i press the button(which has an onClickListener) the application cracks and tells me on the screen of the emulator : "The application... has stopped unexpectably.Try again" and i have a "Force close", which of course closes the application.
I cleaned and rebuild the project a lot of times. i have no errors shown.(using eclipse)
this is the layout/main.xml code...

Android :: Setting Values And Display Text In Android Spinner

May 31, 2010

I need help in setting up value and display text in spinner. As per now I am populating my spinner by array adapter e.g. mySpinner.setAdapter(myAdapter);

And as far as I know after doing this the display text and the value of spinner at same position is same. The other attribute that I can get from spinner is the position on the item. Now in my case I want to make spinner like the drop down box, which we have in .NET. Which holds a text and value. Where as text is displayed and value is at back end. So if I change drop down box , I can either use its selected text or value. But its not happening in android spinner case.

For Example:

Text Value
Cat 10
Mountain 5
Stone 9
Fish 14
River 13
Loin 17

So from above array I am only displaying non-living objects text, and what I want is that when user select them I get there value i.e. like when Mountain selected I get 5. I hope this example made my question a bit more clear.

Android :: How To Accept An Incoming Call By Clicking A Button

May 6, 2010

I'm trying to implement my own phone call handling UI. What I want to do is, if a call comes in, the incoming telephone number and a picture are displayed, and, if I press a button, the incoming call will be accepted/answered.

Sadly, the code does not work. At first, an exception is thrown if I press my answer button:
ActivityNotFoundException: No Activity found to handle Intent {act=android.intent.action.ANSWER

Then I added an entry in the AndroidManifest.xml: I run the app again, there is no exception anymore. However, I doubt the incoming call is not really accepted. Because if the press the Android's screen answer button (green button), the incoming call is accepted and a green in call icon is also displayed on the upper left corner of the emulator screen, while my app doesn't.

I also read the Phone app's source code in android source. There is method such as acceptCall() in the Phone class. But these codes seem difficult for me to use, because there are many imports declaration in the code, such as :

import com.android.internal.telephony.Call;
import com.android.internal.telephony.CallStateException;
import com.android.internal.telephony.CallerInfo;
import com.android.internal.telephony.CallerInfoAsyncQuery;
import com.android.internal.telephony.Connection;
import com.android.internal.telephony.MmiCode;
import com.android.internal.telephony.Phone;

And, if I add these imports in my code, there will be too many errors, such as : "The import com.android.internal.telephony cannot be resolved" What is the right and simple way for my problem?

Android :: Spinner Display The Radio Button In Textview?

Oct 27, 2010

i have a spinner with an arrayadapter that is dynamically managed. when it gets displayed, the spinner text also displays the radio button. how do i get rid of this radio button?
NOTE: i'm not talking about the radio buttons that appear in the list that is displayed when i select the drop down on the spinner.

here is a pic of what it looks like: SIGH cannot upload image as i don't have 10 pts. so i've found a link: http://www.slashresources.com/android-gui-examples/ scroll down about 1/2 way and find the spinner example on that page. and my spinner looks like the spinner thats grayed out by the list. notice how the drop down arrow is all strecthed and yucky... thats my problem.

Here are the appropriate code snippet... couple of points:

This code is in the constructor of widget which is a subclass of Spinner value is an array of Object instances (passed when the widget gets created) there are no XML resources; all widgets are dynamically created thinking i need to "manipulate" the prompt, i added setPrompt(...) in the constructor and also in the onitemclicked event listener... this had no effect.

Q: what am i missing? seems to me i'm missing some attribute of the Spinner which is causing the radio button to also display in the text part of the spinner.

-- snip code --

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

-- end snip code --
