So I'm a noob when comes to android programing. Can someone tell me if the "Complete Action Using" dialog box is suppose to set the defaults when you use the "Always" response? Personally I thought it was however in my programming I have not been able to get it to use the "always" response always. What I mean is if I have "Google Music" installed and then I want to kick off the music player i ALWAYS get the "Complete Action Using" dialog popup.
To remove my code I went back to the Android developers first app program and used that. The SendMessage code now looks like this below. When running this on the emulator the "Complete Action Using" popup always comes up irrespective of selecting "Always" or "Just Once". What have I missed or done wrong?
Code:
public void sendMessage(View view) {
// Do something in response to button
if(android.os.Build.VERSION.SDK_INT>=15){
Intent intent=Intent.makeMainSelectorActivity(Intent.ACTION_MAIN,
Intent.CATEGORY_APP_MUSIC);
startActivity(intent);
}else{
Intent intent = new Intent("android.intent.action.MUSIC_PLAYER");//Min SDK 8 and deprecated in API 17 for makeMainSelectoryActivity
startActivity(intent);
}
}

If you select "Always", the default application will be set which you can remove from the settings.
However, there should be a better possibility to do this.
You could try to use the unofficial Google Music API.
EDIT: If you just want to start Google Music use that code:
Code:
Intent LaunchIntent = getPackageManager().getLaunchIntentForPackage("com.package.address"); //replace the package name
startActivity(LaunchIntent);

Actually you can not use this to set a default application. You can try this in the emulator. The selection of Always does not impact the default application setting.
It appears that the Confirmation of "Always" and "Just Once" when ACTION_MAIN is used with a CATEGORY is a misnormer altogether. A default is only set when an Intent contains a mime type. So if you did not use ACTION_MAIN but say GET_CONTENT with a type of audio/* then you can launch with a default player.
Try it your self in the emulator this never sets a default. Seems everyone says it does but certainly the emulator and a real device support the outcomes that a default is never established through his call at all.
Stll looking for a answer but at least I now know that the above will always prompt you to select an application irrespective of any defaults set.
did you try it on a device?

you mean my original code. Yes I did and the way it behaves is as described. I also went debugging what the makemainselector actually does under these situations. It actually registers the selected application in the packagemanager against the "Android device". Subsequent calls with the APP_MUSIC Category do not get found for some reason. Its like the code does not look for the application that is registered but asks for the number of applications that support the category and then throws a prompt rather than checking if there is a existing default. So either the makemainselector is the wrong thing to use or this just behaves incorrectly. When looking through the developer apps it does state to use makemainselectoractivity for API>15 as the action for the <15 intent of MUSIC_PLAYER is deprecated. However, an intent using MUSIC_PLAYER works corrctly and kicks off the default where as makemainselectoractivity seems to set the default, and kick off the app but does this every time. So either the documentation is incorrect or the code has a bug. If I get time I'll try and look through the code but at present it does not seem that this actually works to select a default allocated application and use it......you have to put up with being prompted and then selecting an option or double clicking every time.
Code:
Intent intent=Intent.makeMainSelectorActivity(Intent.ACTION_MAIN,
Intent.CATEGORY_APP_MUSIC);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);//Min SDK 15
PackageManager pm = this.getPackageManager();
final ResolveInfo mInfo = pm.resolveActivity(intent, 0);
Toast.makeText(this, pm.getApplicationLabel(mInfo.activityInfo.applicationInfo), Toast.LENGTH_LONG).show();
startActivity(intent);

Hi all,
I am using eVC++ 4.0, and i've dynamically created a CListView like this:
Code:
lv.Create(0,_T(""),WS_CHILD|WS_VISIBLE,r,this,5);
but I dont know how to handle the events of this control... any ideas??
Mohammad
To get events from a listview (win32) I normally subclass it. I use the subclassing routine to post a message back to the parent when the user is doing something like tapping on it, then the windows routine can check whats selected etc and act on it. Is subclassing possible in mfc ?( I don't use it).
Thank u
but can anybody post some code??
thnx
Ok, I am a bit lazy to look up code at the moment, but here's something:
Yes, subclassing is possible in MFC. You just derive your class from the basic class provided like this:
Code:
class MyListView : pubic CListView
Then you add message handlers in the normal matter.
EDIT: The following passage is incorrect:
But I think subclassing may not be necessary in you case. List box controls send WM_COMMAND messages with notifications of major events like selection change to the parent window. All you have to do is to create a WM_COMMAND handler in your parent class.
Sorry I was thinking of ListBox not list view when I wrote it.
To manually add message handlers you need to put macros like ON_MESAGE or ON_COMMAND in the DECLARE_MESSAGE_MAP section of the class cpp file. All the detaisl are available on MSDN.
Are you saying that a listview will send the same WM_COMMAND as a list box in mfc? Dose this also happen in win32 made listviews. I have always thought it was a bit too tedious to find out when the user taps an item in the listview.
After reading your post levenum I had a quick look and it says that a WM_NOTIFY gets sent to the parent with a LVN_ITEMCHANGED for example. I had not used the LVN_**** because when I looked at them there was none that seem to deal with selections. I would guess that LVN_ITEMACTIVATE or LVN_ODSTATECHANGED would be usefull for this but then a second tap would not be picked up still leaving me wanting subclassing in many situations to get the users tap.
Ok, I have read what u wrote guys and my problem is almost solved, I used the OnNotify() method to handle messages sent from child controls like this:
Code:
BOOL CTest2Dlg::OnNotify(WPARAM wParam, LPARAM lParam, LRESULT* pResult)
{
// TODO: Add your specialized code here and/or call the base class
if(wParam ==5 ) //5 is control ID
{
NMHDR *ph =(NMHDR*)lParam;
if(ph->code==NM_CLICK)
MessageBox("Click");
else if(ph->code==HDN_ITEMCLICK)
MessageBox("Item Click");
else
{
CString str;
str.Format("%d",ph->code);
MessageBox(str);
}
}
return CDialog::OnNotify(wParam, lParam, pResult);
}
Now there still a very small prolem: what messages should I handle for 'Selected Item Changed' event ?? I know its easy but I couldnt find it
Regards
mohgdeisat: I am sorry, I made a mistake about WM_COMMAND.
OdeeanRDeathshead is right, I was thinking of a list box not list view.
To make up for this, here is some sample code from a win32 dialog app that uses list view control. I hope it will be of some help:
Code:
//this is from the dialog window function:
case WM_NOTIFY: //handle events:
nmhdr = (LPNMHDR)lParam;
switch (nmhdr->idFrom)
{
case IDC_LEDLIST: //list control ID.
return OnLEDListEvent(hwndDlg, (LPNMLISTVIEW)lParam);
break;
}
break;
BOOL OnLEDListEvent(HWND hwndDlg, LPNMLISTVIEW nmlv)
{
/////
// Handles list view control notification messages
switch (nmlv->hdr.code)
{
case LVN_ITEMCHANGED:
return OnLEDListItemChanged(hwndDlg, nmlv);
break;
}
return 0;
}
BOOL OnLEDListItemChanged(HWND hwndDlg, LPNMLISTVIEW nmlv)
{
if (ListView_GetSelectionMark(nmlv->hdr.hwndFrom) != nmlv->iItem) return 0;
/* do what you need here */
return 0;
}
Don't mind the fact that I used 3 different functions. This is part of a bigger program and I am trying to keep things well organized without resorting to classes.
As I understand it, LVN_ITEMCHANGE is received for different reasons so I try to handle only the one coming from selected item. LVN_ITEMACTIVATE is only sent when you double click the item so if you just want to catch selection change you need to use LVN_ITEMCHANGE.
Once again, sorry for confusing you before.
thanx pals, good job!!!
I think my problem is now solved with ur help :wink:
Mohammad
Ok guys, I said that my problem was solved, yet, another problem arises...
When the list view is in the report mode, how can I determine when a header button is clicked, and determine which one was clicked???????
thanx in advance
To identify a header column click, you need to handle the WM_NOTIFY/HDN_ITEMCLICK message. Normally this message will be received by the header's parent control (i.e. the listview) -- some frameworks may redirect the message to the header control itself. I haven't worked with MFC in 10 years so I can't really if it reflects notification messages back to the control.
If you're trying to implement column sort, do yourself a favor and check out the Windows Template Library (WTL) at sourceforge.net. It's a set of C++ template classes that provide a thin yet useful wrapper around the standard Windows UI components. One of the classes is a sortable listview control. I've been using WTL with big Windows for more than 5 years -- you couldn't pay me to go back to MFC.
hi,
I have seen the WTL library and it seems very useful and time-saver, but I have a couple of questions about it:
1. can WTL 8.0 be installed with VC++ 6.0, specifically the appwizard stuff??how?? I see only javascript files of vc7.0 and 7.1 and 8.0!!
2. is there a good documentation about those classes??
Mohammad
I don't know about WTL 8; I'm still using WTL 7.5 with VS .Net 2003 for all my Win32 development. My guess is that it wouldn't work too well, as WTL is based on ATL, which has substantially changed between VC 6 and 7.
Good references for WTL include www.codeproject.com/wtl, and the WTL group over at Yahoo groups (reflected at www.gmane.org).
OK I've been looking for a while now. I'm trying to make a very simple app. what i want it to do is when i type a key word or phrase into a text box and hit the "GO" button i want the text that was typed to the text box to be inserted into a string which will be opened in the browser and search Google.
to clarify, basically taking the "Google Hacks" application for pc and writing it for android. i didn't think it was going to be that hard to do, but i cant find any examples of taking text from the text box and having it inserted in between the ""
-inurlhtm|html|php) intitle:"index of" +"last modified" +"parent directory" +description +size +(.mp3|.wma) ""
could anyone help me? i plan on later making it more like the pc app but right now just search for music, the apks and pics, etc...
may be
Intent intent = new Intent();
intent.setAction(Intent.ACTION_WEB_SEARCH);
intent.putExtra(SearchManager.QUERY,"searchString")
startActivity(intent);
search string can we get by TextView.getText().toString
thanks ill give it a try
I saw a lot of ppl having this problem and it's something SO common to do, and the solutions I saw were ugly to the point that I bet that Google's solution for it isn't any of those.
Simple scenario, I have a few dialogues in my application being setup inside:
Code:
protected Dialog onCreateDialog(int id) {
switch(id){
case DIALOG_LOAD: return new ProgressDialog... etc.. etc..
}
}
and called with
Code:
showDialog(DIALOG_LOAD);
and dismissed with
Code:
dismissDialog(DIALOG_LOAD);
all inside the activity class.
This approach to dialogues I believe is the 'cleanest' way of doing it and just let the Activity manages the dialogues.
it works fines IF I don't rotate the device, I though because the activity was managing it, it would be all inclusive, but no, life is never that simple. If I rotate the phone when the dialogue is up, the rotation occurs, the dialogue is still visible but the moment the code try to dismiss it it gives a nice:
05-26 20:07:02.951: ERROR/AndroidRuntime(10041): java.lang.IllegalArgumentException: no dialog with id 1 was ever shown via Activity#showDialog
so...
do I have to care about dismissing and re-creating the dialogue onPause and onResume or is there anything I can do to make the activity take care of it by itself?
So, I wrote this block of code:
Code:
ContentValues values = new ContentValues();
values.put(BookmarkColumns.BOOKMARK, "1");
values.put(BookmarkColumns.CREATED, "1311170108");
values.put(BookmarkColumns.DATE, "1311170708");
values.put(BookmarkColumns.FAVICON, "favicon");
values.put(BookmarkColumns.TITLE, "XDA");
values.put(BookmarkColumns.URL, "http://forum.xda-developers.com");
values.put(BookmarkColumns.VISITS, "1");
getContentResolver().insert(Browser.BOOKMARKS_URI, values);
When executed, I get no errors. Looking in the browser bookmarks section, the book mark is not there. If i click the Most Visited tab, this shows up and also has the yellow bookmark star next to it, indicating that it is a bookmark. If i click the star to unbook mark it, and click it again, then view the Bookmarks tab, it shows up.
If I use another piece of code to print out all the bookmarks found after I add it, mine shows up
Even with rebooting, they are not showing.
So I ask, why is it that they are not showing up in the bookmarks page of the browser?
I have tried everything and looked around everywhere, and nothing
Thanks!
there is no sanctioned way of adding a bookmark without user input. the normal way would be a call to android.provider.Browser.saveBookmark()
Code:
public static final void saveBookmark(Context c, String title, String url) {
Intent i = new Intent(Intent.ACTION_INSERT, Browser.BOOKMARKS_URI);
i.putExtra("title", title);
i.putExtra("url", url);
c.startActivity(i);
}
other than that dealing with the DB directly would be the only way to add one. try to follow that startActivity to the dialog and see if there is an intent sent to the Browser telling it the DB was updated

But, even with restarting the device the book marks are not there. Surely the browser updates the database at that point.
But it also dosnt make sense because if the page was shown in the history, it has the bookmarked indicator next to it
I must do all of this in a fully transparent way. Showing that popup for each one will not do :/
there are a few other columns that are interesting. 'user_entered' which can be '0' or '1'
But I think your best bet is to find the dialog that saveBookmark() calls and analyze its src
Here it is addBookmark()
http://www.java2s.com/Open-Source/A...rowser/com/android/browser/Bookmarks.java.htm
It appears to be static. Why not just call this method?
static void addBookmark(Context context, ContentResolver cr, String url, String name, Bitmap thumbnail, boolean retainIcon)
------nvm i think its package restricted

I can't for the life of me find ANYTHING written about how to create a shortcut to an app. All over stackoverflow it's just about having ones app get created as a shortcut onto users own launcher.
I want the user to be able to click my button which opens a dialog, in where the user can then select an app of their choosing, rename the shortcut and lastly hit the "Ok" button which should then let that app sit in my apps fragment until the user decides to remove it.
How would I go about doing this?

To get a list of all installed applications, use
Code:
final PackageManager pm = getPackageManager(); //get a list of installed apps.
List<ApplicationInfo> packages = pm.getInstalledApplications(PackageManager.GET_META_DATA);
To start them just create a new Intent(packageName) and start it with startActivity(intent);

Hey, thanks for the quick reply! That works wonders! Half way already. Thanks a lot.
Now how would I go about having it so that the apps I select in the list of apps stay selected, then upon an onClick of a button they get returned to my fragment (activity)? And to have them saved after that, would I need to read up on sqlite?
