I'm looking for a simple method to search a ViewGroup for a specific view given the id. This ViewGroup could have nested ViewGroups as well, so it needs to be recursive. Anyone know if Android as some type of view iterator? I can't seem to find anything.

I'm looking for a way to iterate a viewgroup to retrieve all child views without calling findViewById(). Does view count and view position line up? So can I get the view count and then use that as a counter to call getChildAt(int index)?

View 1 Replies View RelatedI try to query contacts in a specific group by GroupMembership. But It only works fine with system built-in group "Starred in Android".
My codes is like this:
private static String[] GRP_PROJECTION = new String[] { GroupMembership.PERSON_ID, GroupMembership.GROUP_ID };
Cursor groupCursor = context.getContentResolver(). query(GroupMembership.CONTENT_URI, GRP_PROJECTION, "group_id=" + filterGroup_id, null, null);
Log.d(TAG, "number = "+ getCount());
If filterGroup_id is system built-in group id(Starred in Android), log.d() shows the number of contacts in group. But if filterGroup_id is my self-defined group id, log.d() shows the contacts of person in my defined group is always ZERO! Even there is actually some contacts in my defined group. Is this a bug for SDK1.5 R2?
I have a ViewGroup and it has a few children. And one of them is a TextView ("+id/text"). In my code, I would like to know how can I add a new View or ViewGroup which will be positioned vertically aligned and below the TextView (+"id/text")?I have followed the advice below and try to use TableLayout. As a test, I try to layout statically to make sure things are aligned correctly. Here is my layout xml:
<?xml version="1.0" encoding="utf-8"?>
<TableLayout android:id="@+id/panel" xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"

<TableRow

How to retrieve the index of linearLayout which has "llIndex" as id.
I've got a schedule Class, which is simply a custom ViewGroup (with custom onMeasure() and onLayout()), which enables me to place childs(=events) with LayoutParams for column/row start and column/row end. The number of childs and their LayoutParams depend on database entries.
Now I'm trying to add childs (events) from my database. I'd have to use a Cursor Adapter, so my schedule Class has to extend ListView, right? I tried that but the newView() method of the adapter is never called. Why not? My custom ListView doesn't ask the adapter for childs, no childs are added. I also can't add the childs by hand calling schedule.addView() if I extend from AdapterView.
How can I add events to the schedule with the data from the cursor?

View 1 Replies View RelatedI have a layout xml file with a linear layout. One of the children is again a ViewGroup Relative layout. In my java code i want to change the width of this child Viewgroup for my requirements. I tried this
ViewGroup childViewGroup = (LinearLayout)findViewById(childViewGroup);
LayoutParams l = childViewGroup.getLayoutParams();
l.width = 360;
childViewGroup .setLayoutParams(l);
I couldn't do this because findViewById(childViewGroup) doesn't fetch ViewGroups it does only for Views. Note: I cant define a whole new layout.xml for this minor requirement since it is huge layout file and might cause performance overhead. I wanted to just change the width of the child view group in my java activity code.
I am trying to iterate through all the photo images (produced by ADP1 camera), held on external SD storage in an ADP1. I want to extract the binary data for each image file, determine image size in bytes and send the image data (possibly after compression) over a network conection.
My code is generating an exception when I try to generate a Bitmap based on Photos taken by the ADP1 Camera, stored physically on External SD Card Storage. It looks like the image size is exhausting VM for my application.

Is this even possible without calling a specific package? I have found countless examples of sending email via intent, but I can find nothing about simply opening the default email client on the device via button press (preferably with a chooser dialog in case the user has multiple clients).
View 1 Replies View RelatedI've seen a few other threads on this subject, but none that addresses my need which is to not only find the app in the market via the market uri, but display it as if the user had navigated to it. The closest anyone has gotten to this answer is to show how to bring up the Android Market app and browse for the app you want which shows the single result in a list that the user must still select to get to the screen I want to display.
Here's my existing code that does exactly that:
private static final String MY_MARKET_APP = "com.some.silly.name";
Intent marketLaunch = new Intent(Intent.ACTION_VIEW);
marketLaunch.setData(Uri.parse("market://search?q=pname:" + MY_MARKET_APP));
startActivity(marketLaunch);
I don't want to have to force the user to select this single item from the list - just bypass that and bring up the next screen.
Simple question, what is the fastest way to iterate through collections on Android? I generally use collection.iterator(); and the iterator.next() to iterate through the whole collection. Is it any faster to drop that and iterate with "old" (and I use the term old loosely) for( int i=0; i<collection.size(); i++) ? I was thinking of getting the collection.size() into a separate variable so I wouldn't be asking the collection it's size all the time so basically the for loop would turn into something like this: int size = collection.size(); for( int i=0; i<size; i++ ) collection.get(i); Any better? Speed wise, I mean. I'm in a point where I need to get every possible inch of speed for my application. Or maybe allocate everything into Lists in the start, and once I know the correct amount of data, I turn all that into arrays and drop the Lists so I can have array[index] (Log(1) access, right? OH wait. how did this go again access instead of having the "slow" method calls in between like .get(); when accessing the data in the collection.
And what about getters & setters for Classes? Like let's have a Vector2D class that contains obvious integer x and integer y values. What is the fastest way to access them inside the class? Have them as public and just straight Vector2D.x = someValue; or through getters and setters? I've had much debate with my tutor about this (working on my final year project) but not to get too much into details of it. Also all links for further Android application optimisation are more than welcome and greatly appreciated (I read the googles docs on this already). Plus if you have found some really good tricks / quirks on Android to punish the device even more so it runs faster, do share, do share. Please be gentle on me, I'm such a beginner in all things Android that I feel absolutely dumb as a boot for asking these kind of things. I come from strong C++ / Java background but getting the extra inch of speed for everything on Android is so different than optimizing code for PC side and not that you even have to do it on PC side that often.
Just picked up my incredible, and I have two questions....
1. how do i change the email notification to a specific sound? As of rite now, when i receive an email nothing happens (no sound or vibrate).
2. How do I select a specific ring for mms. I know how to select sms, but I cant figure out how to change the mms.
I have had androids for over two years now and am getting more and more concerned every time I download an app and seeing that it wants to READ my SMS message and Contacts.
Is there a way I can disable reading of SMS messages or any one of the other permissions by specific apps, or all apps?

I am trying to set up a ViewFlipper that changes a SlidingDrawers content each time a button is pressed. So far every view I set up worked fine, but now I am trying to create a ListView (including single_choice_mode) within a child view of the ViewFlipper, but my attempt only let to a NullPointerException. As I only discovered ViewFlipper today, I am not yet familiar with it and may not have understood it completely. if someone could give me a hand and help me find out what I have done wrong, that would be great. Here is what I have done:
The code for the onClick event of the ImageButtons:
public void onClick(View v){
if (v == btnExposure){
mFlipper.setDisplayedChild(0); }
else if (v == btnProperties){
mFlipper.setDisplayedChild(1);}
else if (v == btnSpecialEffects){
mFlipper.setDisplayedChild(2);.............
I have long had my WAP pages built and had my URL launchers built by an outsourced group in India. I now have a requirement to update my .apk files to 2.2 as well as build 6 additional .apk files that are made up of 6 completely different URL launchers to other WAP sites. I have successfully set up my Java and SDK environment My questions are: What is the best recommendation the group can suggest as a starting point? How do I open the .apk file in my eclipse environment to make the changes necessary? The Android Market says the following when I attempt to upload my .apk file: [quote] Market does not accept apks signed with the debug certificate. Create a new certificate that is valid for at least 50 years. Market requires that the certificate used to sign the apk be valid until at least October 22, 2033. Create a new certificate. Market requires the minSdkVersion to be set to a positive 32-bit integer in AndroidManifest.xml. [/quote]

View 2 Replies View RelatedI notice that there's been a bit of controversy in the last couple of days about off-topic posting on this list. As the list home page says, it is intended to be a place to "Discuss developing Android applications using the Android framework". While I find the talk about the Market and wider issues very interesting, I do think it would be better placed on the -discuss list, so that this list can be more focussed on technical issues to do with developing using the SDK.
I wonder if the reason why this list attracts a lot of off-topic stuff is the name? I suspect many people don't see the description and just interpret "android-developers" to be for discussion of issues affecting developers. Perhaps if it was named "android-sdk" (to match the new android-ndk list), that would improve things?
