In my apps preferences screen, i want to pop up a dialog that shows a list of checkbox items that are dynamically generated.
How does one do that and also, how does one get the checked values? I have made custom dialogs in the past, but for some reason my brain wont function today ..

I have two ArrayAdapter<String> to handle the values. I have issue in the display. my xml file is structured as
<Linear Layout>
<ListView> </ListView>
<ListView> </ListView>
<Linear Layout>
its displays the two list items by dividing the screen into two equal parts and scrolls within the list individually.
I wanted the List 1 to be displayed fully and then followed by List 2 and also it should screen should be scroll not with in the list but full screen so that List 2 could be seen below.
i tired many ways but still the results are not fine.

View 1 Replies View RelatedI am making a time sheet program where a user inputs his in- and out-punches. I have a ListView that I am populating from an array of calendar objects. I would like each row to show the day and date then on a new line the time, but I only want to display the day and date if it is different from the previous element.Currently, I am setting visibility in the Base Adapter based on comparisons using position vs position-1 (which are used as indices to the array). This only works if the whole list fits on the screen. If it extends beyond the screen and the user scrolls around the results are unpredictable.To further confuse things, I am setting the color of the times, based on the position, to alternate between green and red (in/out) and it works as expected, scrolling or not.How does Android handle the ListView position when scrolling or what could I do differently to show/hide the day and date? Code...

I have two questions:
1. How do you programmatically generate key strokes? I found some tutorials where it says to use IWindowManager, but that doesn't exist anymore in 1.5. (And WindowManager doesn't provide any function to generate key strokes)
2. How do you programmatically select one item from a ListView? Is it possible to do it with the index of the list item (it's position in the list)
I am using a simple expandable list that is populated by two arrays ( group array for the groups and a multi dimensional children array for the child). The arrays are built dynamically in the program and some group items have more children than others. So I end up defining the highest number as the array size for the multidimensional child array. After populating the child array, some positions are left null, as there are no values for those group items (explained above). When I associate this with the expandable list adapter, the getChildView method throws a nullpointer exception when it comes across a position in child array that does noto have value. I have two questions:
1. Can I make the base adapter skip the shildview method if the value in that child is null? The current implementation of getchildView method has to return a view and even if I suppress the nullpointer exception, it adds a blank element in the child position in the list.
2. Is there a better way of associated multidimensional arrays that are populated at run time? The current set of examples only use hardcoded string array values. Even the cursor adapters examples use very basic setup.
I want to display contact information in a custom layout. My app lets the user select a contact, then I retrieve key pieces of info on that contact (phone #'s, email addy's, etc). I want to display them to the user so they look grouped logically. Sort of like a series of tables, so phone numbers, then email addys, then organization, etc.
I have a table format that I've been using in a different part of the app where I know the exact number of rows I'm adding and I have defined styles for the rows already. I want to reuse those styles for this data, but android sdk won't allow for you to set the style attribute programmatically.
I could create the tables in code and set all the attributes the same as in my defined styles, but it seems like a lot of extra coding.
I have created a broadcast receiver statically by specifying it within the Manifest, and I have also created the "same" broadcast receiver in code and have registered it with the application context. The static way works very well, but the dynamic way does not receive the expected broadcast. It could be that I am not creating the intent filter correctly, or that I need to register it with some other context somewhere. Please see the code examples to see what I am doing. This is related to receiving data SMS, it works very well on a device using a broadcast receiver defined in the Manifest. The correct permissions are set for both examples.
The following is from the Manifest, and the resulting receiver gets the expected broadcasts:
CODE:.....
The following is the code example that doesn't work (it does work with an intent like "android.provider.Telephony.SMS_RECEIVED" but not for data sms):
CODE:.....
The question is - why does this broadcast receiver get notified of the incoming data messages? It seems some other resource is notified when the Manifest version of the receiver is created...

I'm trying to make a simple order system. So the user selects a burger type from a spinner, then the user can enter in the quantity and then there is some math taking place in the background which sets a text view at the bottom with the total price. I'm not sure what method I'm meant to use so that it is updated dynamically when the user changes the text view quantity.
If i just say that all burgers are 2.50, i need some sort of method saying, if/when data is entered into the edit text , take that data and then times it by 2.50 and set it in the total text view below. I'm just unsure on the method part of it so it's dynamic and will change when the edit text quantity is altered.
Code:
package placeorder.com;
import java.util.Random;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;

I have lot of lists: for example: Categories, and subCategories, in my case some Categories has subcategories, So What I want to do, is if the categories has subcategories I want to clean the recently list and show the subcategories,(This can be solved by creating new activity for only subcategories, but I would say that the most of the code woyld same)I wounder how can I updoate list whit new data?If possible to add some animation when clicking, so the list goes to left when clicking, and showing data comes from right,
View 1 Replies View RelatedLet me start out by saying that I feel like there should be a very simple way to do this, and it's entirely possible I'm missing something very simple. But all the examples I find for transition animations (push left out, push right in, etc.) deal with moving from one view to another. What about an application that only has one view, but dynamically changes the data feeding that view? The best common example of this is the base calendar app. It has identical views, but when you swipe forward or backward the date of the view transitions with a swipe animation. How do I reproduce this? Surely I don't have to inflate ViewFlippers for the same view? And if so, what is the best way to go about this?
View 2 Replies View RelatedI have a String countries[].now when i click a button then on the onClick event this abc array is filled.suppose it is filled with the name of 10 countries.These 10 countries should be visible as a list so that i can choose any 1 country among the list. but i am not able to show them as a list.
My programme crashes if i use the following code :

As countries is filled later on the click of a button.So initially the countries array is empty and as the onCreate() is executed first it crashes.
I found the examples on net where there is pre-defined array.so it works.My array is filled in a onClick event.how can i display List at that moment?

Does it try to load all of them directly how does it wait till the user scrolls and then renders those elements?
