[android-developers] Re: Nexus 2.1 one sale, WHERE is the SDK!
Whole idea of having google superphone and write some main parts of OS as closed source bits for that device is flawed from beginning. On other hand, if your code works on 2.01, then it should work on nexus (except that hw related things). I am missing some big notice on developers page month before, saying : There will be phone with major market penetration, which uses 2.01; fix your apps guys And..android was never a real opensource system. Google is kind to let us access parts main parts of OS, that's it. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] mediastore thumbnails
Hello, I want to display gallery of videos with thumbnails in my app. Is this what MediaStore.Video.Thumbnails.getThumbnail() do? I didn't found way to use it. Other properties of video files are easily accessible (MediaStore.Video.Media.DISPLAY_NAME for example), but there is probably different logic behind that thumbnail class. Anyone know how to fill adapter like it is in Hello views samples?

[android-developers] profiles manager
Hello, One of features od my old n95 I am missing on my new hero is simple management of ringtones and their volumes. I found Locale, which is good, but I think I could use really simpler application just for that. I wrote widget to simple change ringtone and volume from one to another, but this is really unusable, because: I need to change profile mostly with locked phone. Press button + slide screen + press widget is really boring way to do this. This is where it gets interesting. I searched this forums and it looks like we are still not able to make lock screen widget, which will good way to go. So, is it possible to capture any hardware button? I found discussion about home button, and I have to agree that overriding home will ruin user experience. But something like trackball press in sleep mode? Or volume buttons?

I didn't know (and did't expected to be honest) that Google is slower then Microsoft and Apple in this.

I think you can't use the '[ ]' operator on the JSONArray (if

Look at the JSONArray class and see what method is implemented in that

And you have to make sure that the value provided to the 'setText'
method is a CharSequence (e.g. a String).
If you're not familiar with Java, i strongly suggest you do become
familiar with it :-).

Implement your subclass of BaseAdapter (e.g. JSONArrayAdapter).
Implement/override the getCount(), getItem(int position), etc. to make
your BaseAdapter a proper list-adapter around your jsonarray.
Implement the getView method; it provides the 'position' and
'contentView' parameters.
- Use position and getItem(position) to obtain anjson-element from
your jsonarray.
- re-use contentView or create a brand-new one if it is null:
- Assign text/images to the contentView (or its child-view) based
on
thejson-element you got.
Then assign an instance of your JSONArrayAdapter to your list- or grid-
view.
And viola. It should work :)
Take a look at the 'API Demo' in the Android SDK for examples.

Create your own adapter class from BaseAdapter, and you can traverse

[android-developers] Re: jsonarray as listview source
Thanks. This moved my understanding of whole BaseAdapter (which is not
data adapter at all). Now I am frozen on some casting unknown to me
(probably). I created code:
public View getView(int position, View convertView, ViewGroup
parent) {
// A ViewHolder keeps references to children views to
avoid unneccessary calls
// to findViewById() on each row.
ViewHolder holder;
// When convertView is not null, we can reuse it directly,
there is no need
// to reinflate it. We only inflate a new View when the
convertView supplied
// by ListView is null.
if (convertView == null) {
convertView = mInflater.inflate
(R.layout.list_item_icon_text, null);
// Creates a ViewHolder and store references to the
two children views
// we want to bind data to.
holder = new ViewHolder();
holder.text = (TextView) convertView.findViewById
(R.id.text);
holder.text2 = (TextView) convertView.findViewById
(R.id.text2);
holder.icon = (ImageView) convertView.findViewById
(R.id.icon);
convertView.setTag(holder);
} else {
// Get the ViewHolder back to get fast access to the
TextView
// and the ImageView.
holder = (ViewHolder) convertView.getTag();
}
// Bind the data efficiently with the holder.
holder.text.setText(valArray2[position]);
holder.text2.setText(valArray2[position]);
holder.icon.setImageBitmap((position 1) == 1 ? mIcon1 :
mIcon2);
...
Which is basically list14 example from SDK. But, holder.text.setText
(valArray2[position]); returns error that Array is expected and mine
is JSONArray. How to cast my JSONArray to expected format?

Implement your subclass of BaseAdapter (e.g. JSONArrayAdapter).
Implement/override the getCount(), getItem(int position), etc. to make
your BaseAdapter a proper list-adapter around your jsonarray.
Implement the getView method; it provides the 'position' and
'contentView' parameters.
- Use position and getItem(position) to obtain anjson-element from
your jsonarray.
- re-use contentView or create a brand-new one if it is null:
- Assign text/images to the contentView (or its child-view) based
on
thejson-element you got.
Then assign an instance of your JSONArrayAdapter to your list- or grid-
view.
And viola. It should work :)
Take a look at the 'API Demo' in the Android SDK for examples.

BaseAdapter? GetView?
Thanks for any clarification

like perverse to me, is it really necessary?
Create your own adapter class from BaseAdapter, and you can traverse
yourJSONhowever you want.
