[android-developers] Re: CountDownTimer too slow ???
hello Nikolay,
I have updated my code, following your suggestion :
public List times = new ArrayList();
CountDownTimer countDown = new CountDownTimer(Integer.MAX_VALUE, 1000)
{
@Override
public void onTick(long millisUntilFinished) {
times.add(System.currentTimeMillis());
}
};
and after a while I display the time between two call to "onTick" with
a loop over my list :
for (int i = 1; i < times.size(); i++) {
System.out.println(times.get(i) - times.get(i - 1));
}
And I have something like this :
07-25 18:18:37.281: INFO/System.out(408): 1034
07-25 18:18:37.281: INFO/System.out(408): 1031

...
I'm not expecting the precision of an atomic clock, but the error
margin here is huge !

thanks for your response Nick.
The only code in "onTick" is the call to "Log.i()". I don't think it
take more than a second to execute :)

[android-developers] CountDownTimer too slow ???
Run the following code in the emulator and start a chronometer at the
same time :
// log some text each second :
CountDownTimer countDown = new CountDownTimer(Integer.MAX_VALUE, 1000)
{
private int i = 0;
@Override
public void onTick(long millisUntilFinished) {
Log.i("", "###" + i);
i++;
}
@Override
public void onFinish() {}
};
countDown.start();
Then wait a few minutes.
For example I stop when my chronometer was at 7min44s. The value in
the log was 448seconds => 7min28s.
WTF ?!???

ok, this is really strange. I've got a TableLayout with 6 tableRow (defien in xml). I then add (in Java) a button to the first row and another to the second row. I expect the 2 row to be on top of each other, but they are actually next to each other (like columns) ... my Layout : The java code : TableRow p1 = (TableRow) this.findViewById(R.id.TableRow01); TableRow p2 = (TableRow) this.findViewById(R.id.TableRow02); p1.addView(new Button(this)); p2.addView(new Button(this)); I have probably done something stupid and I'm sure there is a simple fix :) -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

It work if I use a TextView instead of my custo layout (see my first

So I cheated and set the picture of the contact as the background of

The newView method now look like this :

float density =
context.getResources().getDisplayMetrics().density;
TextView name = new TextView(context);
name.setText(cursor.getString(1));
name.setTag(cursor.getLong(0));
name.setGravity(Gravity.CENTER_VERTICAL);
name.setTextColor(Color.BLACK);
name.setTextSize(19);
name.setHeight((int) (54 * density));
Uri contactPhotoUri =
ContentUris.withAppendedId(Contacts.CONTENT_URI, cursor.getLong(0));
InputStream image_stream =
Contacts.openContactPhotoInputStream(mContent, contactPhotoUri);
Drawable avatar;
if (image_stream != null) {
Bitmap b = BitmapFactory.decodeStream(image_stream);
avatar = new BitmapDrawable(b);
} else {
avatar =
context.getResources().getDrawable(R.drawable.contact_picture);
}
avatar.setBounds(0, 0, (int) (54 * density), (int) (54 *
density));
name.setCompoundDrawablePadding((int) (3 * density));
name.setCompoundDrawables(avatar, null, null, null);
return name;
}
Also the code in bindView is not needed (don't know why there is 2
methods newView and bindView ...)
@Override
public void bindView(View view, Context context, Cursor cursor) {
// already done in newView
}
So if you want a autocompletetextView which autocomplete on the name
of the contacts and disply their photo you can use this :
Cursor cursor =
getContentResolver().query(ContactsContract.Contacts.CONTENT_URI,
ContactListAdapter.PEOPLE_PROJECTION, null, null,
ContactsContract.Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC");
ContactListAdapter adapter = new ContactListAdapter(this, cursor);
AutoCompleteTextView textView = (AutoCompleteTextView)
findViewById(R.id.AutoCompleteTextView);
textView.setAdapter(adapter);

I did this, but the problem is still here.
Also same problem if I use "(String)null" instead of
"Typeface.SANS_SERIF" (I guess sans serif was the default).

hu ? the only radio button I add are the one returned from the
function :
group.addView(getRadioButton(i));
it is equivalent to the following code (which doesn't work either) :
for (int i = 0; i < 10; i++) {
RadioButton v = new RadioButton(this);
if (i == 3) {
v.setChecked(true);
}
group.addView(v);
}

[android-developers] able to select 2 RadioButton in a RadioGroup ??!??!
hello,
I have a simple RadioGroup in one of my view, with several
RadioButton :
RadioGroup group = new RadioGroup(this.getApplicationContext());
this.setContentView(group);
for (int i = 0; i < 10; i++) {
group.addView(getRadioButton(i));
}
private RadioButton getRadioButton(final int position) {
RadioButton v = new RadioButton(this.getApplicationContext());
if (position == 0) {
v.setChecked(true);
}
return v;
}
It display 10 radio buttons, and one of them is checked (the first
one). But if I click on another radio button, the first one stay
selected ...
Is there something wrong with my code ?

[android-developers] Re: bug with notifyDataSetChanged() in ArrayAdapter ?
Shink, thank you for your answer. the add() and insert() work as expected. However it is a lot easier for me to manipulate directly my ArrayList (it is more flexible and the ArrayAdapter API lack some methods). I think I will keep my current code with the overrided getCount() method so I don't have to add to code to keep the ArrayAdapter in sync with my ArrayList.

[android-developers] Re: bug with notifyDataSetChanged() in ArrayAdapter ?
myArrayList is a simple ArrayList :
ArrayList myArrayList = new ArrayList();
which I give to my adapter in my ListActivity :
adapter = new StepItemAdapter(this, myArrayList);
this.setListAdapter(adapter);
Later I add item to my list and try to refresh the view :
myArrayList.add(position, new Step());
adapter.notifyDataSetChanged();

[android-developers] Re: bug with notifyDataSetChanged() in ArrayAdapter ?
by "overriding the default ArrayAdapter" I mean overriding the
getView(), getViewTypeCount() and getItemViewType() methods.
This is the recommended way of changing the ways the items are
displayed according to the javadoc, so I guess it should not cause
problem :
"To use something other than TextViews for the array display, for
instance, ImageViews, or to have some of data besides toString()
results fill the views, override getView(int, View, ViewGroup) to
return the type of view you want."
Anyways, I have tried to remove all my overrided methods and the
problem is still there ...

[android-developers] Re: bug with notifyDataSetChanged() in ArrayAdapter ?
the only example I have found for ArrayAdapter in the API example
doesn't show how to add element in the array :
http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/view/List1.html
and getCount() is not overrided in this example ...

[android-developers] bug with notifyDataSetChanged() in ArrayAdapter ?
hello everyone,
I have a strange problem with one of my ListActivity. I have overrided
the default ArrayAdapter in order to customize my list. I have then
filled the adapter with an ArrayList.
If I insert an element on the list and then call
notifyDataSetChanged() on the adapter everything works fine.
But if I insert an element at the END of the list and then call
notifyDataSetChanged(), the new element doesn't appear ...
And finally if I override getCount() on my adapter like this :
@Override
public int getCount() {
return myArrayList.size();
}
then everything works fine.
Is this a bug or am I doing something wrong ?

[android-developers] Re: nullPointerException with custom ArrayAdapter
ok,
I finally have understand what is going on :
I have different layout on my list (R.layout.step_list_item,
R.layout.step_list_item2 ...) for each type of item in my list. When I
insert a new item, android try to re-use the layout which was
previously in the list at the same position. And it use the wrong one
because the type of the item has changed ...
So I remove the "if (convertView == null)" test and re-inflate my
layout each time and everything works fine now.
morale : Premature optimization is the root of all evil.
So now I've got a new question : isn't there a better way to do
this ? It really seem awfully complicated just to have a list with
different kind of items.

[android-developers] Re: nullPointerException with custom ArrayAdapter
hello Brad, thanks for your reply.
Isn't the call to super.getView(...) suppose to do this ?? I already
told the adapter which layout to use (see the constructor of my
adpater on my first post), so it should know which one to inflate.
Anyways I tried something similar to what you suggested :
if (convertView == null) {
convertView =
LayoutInflater.from(getApplicationContext()).inflate(R.layout.step_list_item,
null);
}
but I've got a similar nullPointerException when I call
"findViewById" :
EditText ed = (EditText)
convertView.findViewById(R.id.list_item_sb); // return null
ed.setText("test"); // will crash
Again, it works fine when the list is shown for the first time but it
crash when I use "adapter.notifyDataSetChanged()" ...
So "R.id.list_item_sb" is found in my layout the first time but not
the second time ???
This is getting confusing :(

[android-developers] nullPointerException with custom ArrayAdapter
hello,
I have written a custom ArrayAdapter for a ListActivity :
private class StepItemAdapter extends ArrayAdapter {
public StepItemAdapter(Context context, List objects) {
super(context, R.layout.step_list_item,
R.id.list_item_sb,
objects);
}
@Override
public View getView(final int pos, View convertView, ViewGroup
parent) {
View v = super.getView(pos, convertView, parent); //
will crash
here
// etc ...
}
}
On the "onCreate" method of the activity I tell the activity to use
this adapter with a list of object I get from somewhere else
("t.getSteps()") :
adapter = new StepItemAdapter(this, t.getSteps());
this.setListAdapter(adapter);
Everything works fine and the activity is displayed. But if I add a
new object to the list and tell the adapter to refresh the view I've
got an error :
t.getSteps().add(3, new Step());
adapter.notifyDataSetChanged();
The "getView" method of my adapter is called, which is ok since the
list view need to be updated, but I've got an exception on the call to
"super.getView(pos, convertView, parent)".
The stack trace :
java.lang.NullPointerException
at
android.widget.ArrayAdapter.createViewFromResource(ArrayAdapter.java:
355)
at android.widget.ArrayAdapter.getView(ArrayAdapter.java:323)
at pkr.tm.activities.EditTemplateActivity

Do you guy have any ideas of what is going on ??

[android-developers] cuztomized ListView
hello, I'm trying to reproduce the list view that can be seen in the browser when you hit the menu key then "windows" (see this screenshot : http://picasaweb.google.fr/lh/photo/o7uzrwYGcZizwrKlAkRspONA9k7APX93itjEb0IPq5c?feat=directlink). The 2 features I want is the "new" button at the top and the "delete" button on the right. - problem #1 : I have managed to put a button on the top of my list using the "addHeaderView" method. But it look like, well, a button instead of looking like a list item ... - problem #2 : how can I put button on the right of the list items like the "delete" buttons ? - subsidiary problem : why the hell can't i use the keyboard in the emulator ? Chinese character keep appearing :( Do you have any ideas of how this particular screen is implemented in the android browser ?

Hi Dianne,
Thanks for this enlightening info.
I finally used the android:launchMode="singleTask" option in my

I will look into to the documentation of the LocalService the next days.
