I'm trying to make a countdown timer. It works without a button but then it starts instantly so you can't enter a value for the start. Here is the java, as I said nothing appears in the logcat. The error occurs when the button is clicked.
package timer.test;
import android.app.Activity;
import android.os.Bundle;
import android.os.CountDownTimer;
[code]...
The xml page only has a TextView, EditText and Button.

I have just started my career as an android programmer, and am currently relying heavily on the sample code and api examples. I have been working with this api example, to produce an expandable list of items (note this example does not use the ExpadableListView).In playing with the example, I tried to add another widget that would become visible and be gone at the same time as the text (mDialogue in the sample code). This works well with another TextView, but as soon as I tried to add a button widget, it stopped working. The list would expand on first click, showing my hidden TextView and Button, but it will not disappear on further clicks. The button is however, clickable, and I was able to set up an onClick listener to change the button text back and forth.I'm starting to wonder, is it just not possible to have a clickable item inside a clickable list item? Or is there some kind of work around? Would it solve my problem if I used ExpandableListView?

I have an Android app modeled after the LunarLander example by Google.
I am debugging it on a real device, (Motorola Droid) with Android 2.0.
When the orientation changes, the program crashes on a null pointer Exception.
Logcat from just before crash:
CODE:.............
The first line that worries me is "Something wrong here" at 24:38.620. I have no idea what it means, But I think its due to me not reacting properly to the screen change.
Next I get a debug message that I printed myself from within my own method surfaceChanged() about the new surface dimensions.
Then I print out debug message about whether flies was null. flies is the field that eventually causes the NullPointerException. Its created once, and never written to again for the rest of the program. I know that it was not null before the crash, because it was read several times.
Does anyone have a clue how my private member variable came to be null just by these clues?
I would include code but there is a lot of it and I don't know what would be relevant.
II am having the code below. The thing is that right now the word changes to the left, center or right from the moment I click a RadioButton. I actually wants it to change only if I click the Generate button.

TextView textOut;
EditText textIn;

I want, that when the user clicks on a button, a textfield with a number will increase or decrease. But this should be work in a way, that the user leaves the finger on the button and the number increases automatically. Therefore he doesn´t have to click lot of times.I have not found any method to override that could implement such behaviour! Does anybody know how to implement this?
View 2 Replies View RelatedI am trying to follow a tutorial to learn how to get to a new screen on a button click. The issue I feel I am facing is that in this tutorial they have a file named main.java, firstly I don't have such a file. I think I named the file as name1.java and on this screen i have everything going on including this button I am trying to make. So I m really confused as in this article below they have the main.java file and from that file they are moving to screen 1 and screen 2. Is it so important to have a main.java from where we branch the two activities?

I am currently working on an app and I want to lay a Bitmap over the Google Maps bitmap with the click of a button. I am assuming this is possible, and maybe a lot easier than I'm making it.

I created a ListView that contains a row which in turn contain text and a button. The idea is to have the button function as a delete button to remove the row from the list as well as the database. I order to do this I created an adapter to handle the button click. This code is below. Deleting the database record works fine, but I have not yet succeeded in refreshing the ListView so the record will no longer be displayed.
public class FeedArrayAdapter extends ArrayAdapter {
private ARssEReaderDBAdapter dba;
private String TAG = "FeedArrayAdapter";
private View v;
private ListView feedList;..............
Each row of my view look like that:.............
When I click on the ImageButton "arrow", I trigger a method than need the id of the row to perform. By ID I mean the value of the field "_id" of the corresponding record in database. I did not find a direct way to do it, but I think I can if I get the index of the row in the ListView. Again, I don't know how to get this index from a click to a childview.

View 2 Replies View RelatedWondering if I'm going about this the right way or not. I have 3 buttons on my screen (Restart, Previous, Next). When the view loads it shows the first image which is fine. When I click the "Next" button I want it to load a second image and so on for up to 9 images. If I click the "Previous" button it should go back one image. Clicking "Restart" should go to the first image. I have the Restart one working. I'm having trouble with the Next button because it only shows the second image (I think because my "a" variable is initialized at 0).
View 1 Replies View RelatedI have been reading a lot of comments on how it is more lightweight to use views instead of intents in setContent when using tabs.
Since I will be creating an app with tabs, I am trying to implement this instead of having intents inside setContent. However, I am having a difficult time looking for examples or straightforward tutorials on swapping the current view with another one.
Say I have TAB_A, with some entry fields and a button. When the user clicks on the button, a TextView will display "Hello, user!" in the same TAB_A. Of course this is an oversimplified example, but it will surely point me in the right direction.
EDIT: I have a tab called TAB_A with a button in it. If the user clicks on that button, TAB_A will now display "Hello, user!" instead of the button.
Here is a sample of my TabSpec.
CODE:..............
Where ShowButton and ShowHello are classes both extending LinearLayout. Both are initialized in onCreate like this:
CODE:.............
When the app first starts, the user sees the view showButton. When the user clicks on the button, I want the tab to change its contents to showHello.
The question then is: Is there any way to update the contents of the tabspec without using startActivity?
I have an application, when it launches I have to disable all the buttons, I successeded in disabling end call and other i need to disable home buttom if I click it, It should not produce any action.
