[android-beginners] Re: Get file name from Uri
Hi,
The problem is that it should be documented in the Android Reference,
here:
http://developer.android.com/reference/android/provider/MediaStore.Images.html
http://developer.android.com/reference/android/provider/MediaStore.Images.ImageColumns.html
But, as far as i understand, it's not complete. Fortunately, we can
check it in a different way.
android code
Uri u = MediaStore.Images.Media.EXTERNAL_CONTENT_URI; //sdcard
only
Cursor c = managedQuery(u, null, null, null, null);
if (c.moveToFirst()) {
do {
int max = c.getColumnCount();
for (int i = 0; i max; i++) {
String colName = c.getColumnName(i);
String value = c
.getString(c.getColumnIndex(colName));
if (colName != null){
Log.d(columnName: , colName);
}
if (value != null) {
Log.d(value, value);
}
}
} while (c.moveToNext());
}
/android code
Check LogCat and you'll notice that we have all column names with
their values. I suppose, you'd be interested in:
07-22 12:50:09.973: DEBUG/columnName:(3049): _data
07-22 12:50:09.973: DEBUG/value(3049): /sdcard/download/vienna-s-
schonbrunn-zoo-and-giant-ferris-wheel-in-vienna-1.jpg
(...)
07-22 12:50:09.983: DEBUG/columnName:(3049): _display_name
07-22 12:50:09.983: DEBUG/value(3049): vienna-s-schonbrunn-zoo-and-
giant-ferris-wheel-in-vienna-1.jpg
If you have got any questions, don't hesitate to ask.
Greetings!

[android-beginners] Re: a question about final variable and multiple constructors
Hi
First of all, your code is a mess, and you shouldn't attach such
snippets. Please be more careful, and make sure it'd be easy to read
and compile. If it's not possible to compile then at least eliminate
the most basic errors (e.g. mHandleId has no type, there is no class
declaration etc.). Then, there is no x field in your code ;)
Now, to the point. You can declare blank (without value) finals, but
then all constructors MUST initialize it. This is a Java rule. So,
either initialize it in all constructors, or remove the first two of
them [constructors] if not needed.

Hi
I ran into a compiler error saying The blank final field x may
not have been initialized while I was extending ViewGroup to make
another UI thing by modifying SlidingDrawer.
The fact is I'd already assigned some value to my final variable in
the 3rd constructor from ViewGroup, and I left the 1st and 2nd
constructors nothing but the auto-genned super()s.
But for some reason this error only showed up at the 1st
constructor. And if I commented out the first constructor, the error
will just disappear instead of complaining about my empty 2nd
constructor.
I'm new to Java and Eclipse, so not sure if this is a Java or
Android thing, hope somebody stump upon here happens to have some
clue :)
BTW my code:
private final mHandleId;
private final mContentId;
public DeckView(Context context) {
super(context);
// TODO Auto-generated constructor stub
}
public DeckView(Context context, AttributeSet attrs) {
this(context, attrs, 0);
}
public DeckView(Context context, AttributeSet attrs, int defStyle)
{
super(context, attrs, defStyle);
TypedArray a = context.obtainStyledAttributes
(attrs,R.styleable.DeckView,defStyle,0);
int orientation = a.getInt
(R.styleable.SlidingDrawer_orientation, ORIENTATION_HORIZONTAL);
mVertical = orientation == ORIENTATION_HORIZONTAL;
mBottomOffset=(int)a.getDimension
(R.styleable.SlidingDrawer_bottomOffset, 0.0f);
mTopOffset=(int)a.getDimension
(R.styleable.SlidingDrawer_topOffset,0.0f);
mAllowSingleTap=a.getBoolean
(R.styleable.SlidingDrawer_allowSingleTap, true);
int handleID = a.getResourceId
(R.styleable.SlidingDrawer_handle, 0);
if(handleID == 0) {
throw new IllegalArgumentException(The handle attribute
is required and must refer to a valid child);
}
int contentID = a.getResourceId
(R.styleable.SlidingDrawer_content, 0);
if(contentID == 0) {
throw new IllegalArgumentException(The content attribute
is requried and must refer to a valid child);
}
mHandleId = handleID;
mContentId = contentID;
a.recycle();
setAlwaysDrawnWithCacheEnabled(false);
}

[android-beginners] Re: Get file name from Uri
Hi,
Firstly, I'd like to recommend this article:
http://developer.android.com/guide/topics/providers/content-providers.html
Secondly, let's solve your problem (which you can solve on your own
after reading the article). The Uri is not supposed to carry a large
amount of data. You don't cast it to huge objects and directly query
it for the information. Think of it as an address. When you have an
address and a mean of transport you can get there and find whatever
you're looking for. To the point, if you have an Uri, you can use
Cursor and make a proper query, which can look like this:
android code
Uri u = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
Uri u2 = Uri.withAppendedPath(u, 1);
// this is what you have
// u2 == content://media/external/images/media/1
String[] projection = { MediaStore.Images.ImageColumns.DATA, /
*col1*/
MediaStore.Images.ImageColumns.DISPLAY_NAME
/*col2*/};
Cursor c = managedQuery(u2, projection, null, null, null);
if (c!=null c.moveToFirst()) {
String column0Value = c.getString(0);
String column1Value = c.getString(1);
Log.d(Data,column0Value);
Log.d(Display name,column1Value);
}
/android code
Obviously, you can reduce number of columns to the one you need the
most. The less number of columns we have to return, the more efficient
it will get.
On Jul 22, 8:41 pm, Mina Shokry minasho...@gmail.com wrote:
thank you for this great help but unfortunately this isn't my case.
not me who created the cursor and iterate through it. I am just
receiving the Uri from another activity via an intent. and it isn't
good to iterate through all images to find one its Uri matches one I
received especially that I am not sure it will always be a Uri of an
image.
still can I get the file name?

[android-beginners] Re: How to get the text value that has been entered in a dialog box?(AlertDialog)
Hi,
These are my first steps in Android, so my solution might not be
perfect, yet it works.
First of all, you should create a member in AlertDialogSamples class:
private int dialogSingleChoiceOption=0; //0, because Map is
the default choice
Secondly, you have to act when somebody clicks on the dialog:
/* User clicked on a radio button do some stuff */
dialogSingleChoiceOption = whichButton;
Finally, to read the result when sb clicks OK:
/* User clicked Yes so do some stuff */
String[] strArr = getResources().getStringArray
(R.array.select_dialog_items2);
String result = strArr[dialogSingleChoiceOption];
Log.d(!Result,result);
I recommend these two links:
http://developer.android.com/guide/topics/resources/resources-i18n.html
http://developer.android.com/guide/topics/resources/available-resources.html
Any questions?
