[android-beginners] AlertDialog spawning another AlertDialog
Hello,
I've written a camera application which presents the user with a set
of pre-defined tags to choose from. I've done this using an
alertdialog which fires an intent when the user presses one of the tag
options. I want to be able to get the user to add their own tag if
they feel the listed ones aren't appropriate. If the user selects the
'add new tag' option from the first alertdialog i want it to give them
a text box to type in some text, which if selected fires off an
alert. Whats the best way to go about this? I've been playing around
with the alertdialog spawning another AlertDialog with an edittext box
and an ok button but can't get it working. Any pointers?
Thanks,
George

[android-beginners] Subclassed ImageView does not draw in Gallery View
I am subclassing the ImageView class and adding to the Gallery View.
But, nothing seems to get drawn in the expected location; though I can
fling through the Gallery list. I added an image from a resource, and
it shows up correctly in the Gallery.
Any idea on why this may be happening?
Here is the code I am using:
public class CustomCanvas extends Activity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Gallery g = (Gallery) findViewById(R.id.gallery);
g.setAdapter(new ImageAdapter(this));
}
private class CustomImageView extends ImageView {
public CustomImageView(Context context) {
this(context, null);
}
public CustomImageView(Context context, AttributeSet attrs) {
this(context, attrs, 0);
}
public CustomImageView(Context context, AttributeSet attrs, int
defStyle) {
super(context, attrs, defStyle);
}
protected void onDraw(Canvas canvas)
{
canvas.drawColor(Color.BLUE);
}
}
private class ImageAdapter extends BaseAdapter{
public ImageAdapter(Context c) {
mContext = c;
}
public int getCount() {
return 2;
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup
parent) {
if (position == 1)
{
ImageView i = new ImageView(mContext);
i.setImageResource(R.drawable.icon);
return i;
}
else
{
CustomImageView w = new CustomImageView(mContext);
w.invalidate();
return w;
}
}
private Context mContext;
}
}

[android-beginners] OnDraw in subclass of ImageView not working with custom canvas drawing
I subclassed the ImageView class inorder to draw a Picture in an
ImageView. The ImageView is added to a Gallery
In my activity class:
Gallery g = (Gallery) findViewById(R.id.gallery);
g.setAdapter(new ImageAdapter(this));
My Adapter class:
private class ImageAdapter extends BaseAdapter{
..
public View getView(int position, View convertView, ViewGroup parent)
{
MyImageView m = new MyImageView(mContext); //where mContext my
main Activity
return m;
}
}
In my custom ImageView class: I have the following in my OnDraw
method
protected void onDraw(Canvas canvas)
{
super.OnDraw(canvas);
canvas.drawColor(Color.BLUE);
}
There is no change - the area is still black.
If I use setImageResource and then have the following in OnDraw
(canvas)
protected void onDraw(Canvas canvas)
{
super.OnDraw(canvas);
}
The image shows up correctly.
Any ideas on why my drawColor(Color.BLUE) is not taking effect in the
Gallery?

[android-beginners] Services and proximity alerts
Hello, I'm trying to develop a service that will contain a list of gps locations and distances which will be periodically checked to see if the user is in one of those locations. Ideally, if a user is in the location they will be given an option of taking a photo or ignoring the request. This service will be independent of other applications, i only want it for notification really. I've been looking at the services documentation but i'm still lost where to start.

[android-beginners] Re: Camera class doesn't save exif data?
I've tried reading the exif data with os x's 'more info' and EXIF
viewer for os x. They both show exif data for photos taken with the
native camera app, but don't show anything for any of the photos i
take with my own app.
I was poking around the source code last night and noticed..
ImageManager.instance().addImage(..) - the source code of which seems
to be doing stuff with exif information. Should i be using the
ImageManager to save the images? I still can't for the life of me see
where the rest of the EXIF information comes from either!
Any ideas?

Ah ok. Surely i should be getting exif data written then, even without
the geo exif data? Could it be something to do with the way im saving
the image? I can't think of much else! Unless is the developer g1
phone im using to test this on?
Bitmap bm = BitmapFactory.decodeByteArray
(data, 0, data.length);
values.put
(MediaStore.Images.Media.DISPLAY_NAME, Picture);
values.put
(MediaStore.Images.Media.DESCRIPTION, taken with g1);
values.put(MediaStore.Images.Media.MIME_TYPE,
image/jpeg);
Uri uri = getContentResolver().insert
(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
try {
OutputStream outStream =
getContentResolver().openOutputStream(uri);
bm.compress
(Bitmap.CompressFormat.JPEG, 85, outStream);
outStream.close();
} catch (Exception e) {
Log.e(TAG, exception while writing
image, e);
}

As far as I can tell, the only information we pass down through
theCamera.java layer to thecameradriver is geo-location. All the other
EXIF data comes from the driver itself.
ImageManager can be used to write additional EXIF data, but I believe
that requires a full read/write sequence (whereas going through
thecameradriver, all the data is written along with the image).
This is one of the areas I want to improve in the next release
(Donuts).

the geo exif data? Could it be something to do with the way im saving

that requires a full read/write sequence (whereas going through

This is one of the areas I want to improve in the next release
(Donuts).
