View 2 Replies View RelatedI'm trying to create a multiple selection list where the selection is represented graphically rather than with checkboxes.My list has checkboxes, but I want them to serve a different purpose. I'm using a cursor to hold my data and created a custom view binder for the SimpleCursorAdapter. I did this for the checkboxes and general flexibility.So far I haven't even been able to show one line as being selected. I've enabled multiple selection on the list and denied the children of the list item focusability. I've tried manually changing background color with the position fed in through the list item click listener. But the wrong items get changed and they don't even change to the right color. I've enabled touch focusability with no improvement either.Ideally, I'd like the trackball highlight focus bar to appear in multiple places. But I don't think this is possible unless you use the drawable directly. But I don't know how to find or apply it. My next idea was to have a slim view bar that changes color. But I had the same problem with the wrong item being selected so I never finished trying to guess the index position to see if this would work. My most recent idea is to completely swap out the view for another one if it's selected. But I have no idea how to do this either. I'm thinking of using an array list to store the _id s of the items that need a different view to get around the wierd selection problem. I'm also thinking of passing in the ID field as my from and the selection view as the to for my adapter. Then I'd intercept it with my binder and change the view accordingly. But once again, I'm not sure how to do this successfuly.

View 1 Replies View RelatedI'm creating buttons dynamically.
for(int i=0; i<colSize;i++){
final Button btn = new Button(this);
btn.setText(SectionName[i]);
btn.setTextSize(10);
btn.setPadding(8, 3,8, 3);
btn.setTextColor(Color.WHITE);
btn.setTypeface(Typeface.SERIF, Typeface.BOLD);
btn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
//***Every time that I click my button is selected !:)
btn.setSelected(true);

}
But how could I deselect the other buttons that were selected, I just want one Button selected!
Let's say, there are four apps in the system: app1, app2, app3, app4.
Be default, when the system is up, all apps will be shown in the home screen. Now if we provide a customized log in screen, user A log in, then for this user, he can only see (and use ) app1 and app2. Then A log out, user B log in, he can only see app3 and app4.
Does API provide such capability to load the app list dynamically?
I have touched on this question here, where Christopher gave an answer to this, but I dont really get it so I thought its time to make it a real question, not just a "follow up" =)
As it stands, the application Im writing has 4 different screens:
1. Screen 1 - list of nodes (main screen)
2. Screen 2 - options menu, tableLayout with buttons
3. Screen 3 - navigation
4. Screen 4 - text details on version etc
These screens can be navigated to/from using a "header" View that is placed on top. the header then has 4 different buttons:
+--------------------+
| menu with buttons |
+--------------------+
| |
| |
| |
| C O N T E N T |
| |
| |
| |
+--------------------+
The header is just an XML-file (header.xml) with a few buttons. That header.xml is the included in the Layouts using the include-markup. For example, the main.xml has the line:
<include layout="@layout/header"></include>
The header show up alright, but the question is - what is the correct approach to attach OnClickListeners for the buttons in the header?
Christopher pointed out that you could create an Activity class and do the hooks there, like this:
CODE:............
First, I cant make it work since the method setupHeaderButtons isnt accessible from FirstActivity.
Secondly, is this the right way to go at it?
I have parsed the xml file. now aim is to display contents using list view as dynamically..
How it is possible?
I am on my first Android application and I am on a timeline so details and examples will be useful since my knowledge is still minimal. I want my first screen to present the user with a list of activities to choose from. In my situation it is a recipe app where the user first chooses the type of food, such as, Beef, Chicken, or Pork. I want the application to launch an activity depending on the list item that the user clicked on. I am not sure if I should use a list view, a text view, a scroll view, a list activity, an activity group...

When we create a new activity, in the Android.manifest file, we can set some text for the activity's label. It looks like:
<activity class="MyActivity" android:label="Some text here!">
Is there anyway to access that programatically and change it during runtime? Regards Dileep
I've got an activity for which I've defined an intent filter statically in AndroidManifest.xml. I'd like to register additional intents dynamically to that same intent filter in the activity's onStart() method. Is this possible? I'm trying to avoid having to implement a separate intent receiver class.
View 1 Replies View RelatedI have a custom view (an extension of a TextView) that I want to dynamically add to my Layout (don't want to include it in the main.xml file).
The book says to fetch the RelativeLayout using findViewById() in my java code then create a new instance of my custom view, then use addView on the RelativeLayout to add the new view.
I'm not getting any errors, but when I click my button to add the new view, nothing is happening (view isn't being added). Do I need to set additional properties on my custom view (layout width, layout height for example) in order for it to be shown?

I am writing an app that requires you to be logged in to a service before using it. From my understanding of android so far, you have to choose which activity to launch when you open from the launcher in the manifest. I don't know which activity i want to launch at compile time. I want the user to click the icon, then I check and see if they're logged in, then decide based on that whether to launch the login activity, or the main app activity. Is there a way to do this?
View 1 Replies View RelatedI have a use case in my application, where after certain point, I need to associate an data with an activity. So whenever an intent with an action and the data type is fired, my activity can be opened. I know that it is possible to associate a data type with an activity statically via AndroidManifest.xml.
Is it possible to register the data type for an activity dynamically and programatically?
When views with different type have same id and screen orientation changes,
either java.lang.ClassCastException: android.view.AbsSavedState$1 or java.lang.IllegalArgumentException: Wrong state class -- expecting View State will occur. (depends on the view's order)
Because View.dispatchRestoreInstanceState() checks id only.
You may wonder why anyone would make views with different type to have same id.
But it can happen when you use tab activity.
Imagine you have tab activity with two children activity.
Tab1 is ListActivity and Tab2 is ExpandableListActivity.
Both activity have id of "@android:id/list" but the type of view is different.
This means we cannot use ListActivity & ExpandableListActivit at the same in one tab activity.

I currently have a tab layout with 2 tabs, one tab with a list view and one with the option make strings so I can add them in the list view. Both tabs have their own activity because this made the code much more structured, and I dont have to repeat my self later.
Lets say im in the tab that offer me to create an string, and i press the update list button, how do I update the list view without startActivity()? If i use startActivity(), it starts List.java, and instead of displaying the list in the list view tab, it takes full screen, which defies the purpose of the tab view. In other words, the startActivity() steals the focus from the tab view of the list, and sends it fulscreen.
I want to update the activity in my list view tab, without starting a new activity that goes to fullscreen, and doesnt update the one in the tab.
I am working in an android application that uses a list view. I currently have a XML for the row layout with only one text view. Based on certain conditions, some rows will have one additional button and some other rows may have 2 additional buttons. Can I override the getView method of the adapter class to do this logic? is there any performance issue?

I am writing a program where I need a ListView for which I am using a ListActivity. Each one of the views within the ListView has four buttons, (Off, Dim, Bright and On). Each one of these buttons is configured with it's own OnClickListener when I build the view. This part seems to work ok. However when I have say 5 Views each which has these four buttons, I can tell whether an off, dim, bright or on button was pressed but I cannot tell from which view it was pressed. So for example if my views are devices (Light, Heater and Kettle) I press an "on" button and I know an On button was pressed but how do I get it to tell me the On button for the Light was pressed?

View 2 Replies View RelatedI've a ListView where every element in the list contains a TextView and two different Buttons.I found a solution as described in my answer below. Now I can click/tap the button via the touch screen. However, I can't manually select it with the trackball. It always selects the whole list item and from there goes directly to the next list item ignoring the buttons, even though I set .setFocusable(true) and setClickable (true) for the buttons in getView().This causes that no list item is selectable at all any more. But it didn't help in making the nested buttons selectable.

It's working to a limited extent. I have run into a problem which I have not be able to resolve.
Can anyone point me to a tutorial or code sample, or both where I could see a working example of a list with buttons attached to individual list entries?
How can i make like a list of buttons and the user can add buttons like let say that there is remibder program that you can save notes and to the main activity every note you save a new button get added with some name but how can i do that the program will "remember" how many buttons does she need to use on the main activity and how to put the right text on each one and when you click on it to open the right note.

I can not figure out how to have two buttons on one activity that each lead to new activities. I can get the first button to work but not the second.It would look like:
Activity 1 leads to activity 2 or 3.
Activity 2 leads to activity 4 or 5, etc.
I have a simple question. I am trying to design a simple Android app, which based on keywords searches something and shows a listing view of results. Currently it merely searches SMSes in the cellphone.Here are some of the things I am faced with: I have a simple first page with a textbox and a submit button. It's rendered by "Activity" inherited class call SMS Finder.once I have the results present with me, I want them to be binded to a list view. Showing preview text to limited characters, say 20 chars. Clicking on the same should "ideally" open the inbox (or outbox or whatever) and open the SMS, however that meant I cannot come back to my app easily. So I would rather open the whole SMS in my own app. So clicking on the app should open the SMS in a new screen with complete message, sender info etc. Few questions here, For generic Android phone apps, what are the best practices to make UI as compliant to as many phones? Like what kind of views should I use?
View 1 Replies View RelatedThis is difficult for me to diagnose because the Log doesn't provide the offending code line that indicates what caused it.Running the app in the Emulator seems to work OK until I press Home or Back from the Main Activity. Using Back between the activities in the program seems to work OK, it only fails at the Main. I don't have the app finished yet so I haven't loaded it to a device yet.The Log says there was a null pointer exception so I would like to find why.The log points to the android routines (and I don't appear to have the source for those routines in the emulator-most but not all and these are refering to those I can't access). The log gives up at one point and says "11 more".It would be nice to see the remaining 11 in the hopes that one of them points to the line in my code that caused the offense.I'm looking for ideas on ways to find the error and hopefully cure it.
