Re: [android-beginners] Re: Question about UI Handling
Hi Indicator, I thought what I said was clear. The essence of what I wanted to convey was that there are many UI screens. And there is a navigation possible between these different screens on specific user input e.g. - a button click. I did get my answer as multiple activities and using startActivity(). Anyways, thanks for your reply. Karthik. On Sat, Apr 24, 2010 at 7:05 PM, Indicator Veritatis wrote: > Well, of course the docs will not be clear on that, as YOU are not > very clear on it.

[android-beginners] Re: Question about UI Handling
Well, of course the docs will not be clear on that, as YOU are not very clear on it. What is "continuous different UI screens moving around with the user input" supposed to MEAN? Usually, you want a UI screen to stay in one place while it has focus so that the user CAN enter data. But you seem to want it to move around while it has focus. If not, what DO you mean?

[android-beginners] Re: question about intents
ok, I"ve been searching around and I think I get a little bit of it -
Intent(Intent.ACTION_EDIT,Uri.parse("record")); sends an intent out
and the soundrecorder picks it up - as far as I can tell there's no
explicit call to soundrecorder, but it is the only item in teh system
with an intent listener for ACTION_EDIT and the "record" URI - still
not positive on the details though so any help is appreciated, thanks.

[android-beginners] Re: Question about adapters
I am new as new, but from what I got:
"this" is context. It is "this" in all examples I saw. What is in
parenthesis you will see if you highlight createFromResource in
eclipse. R.array.planets is a string array. It can be created like:
final String[] branches= new String[] {
"Brno", "Černý Most", "Zličín"
};
and then placed in: ...ArrayAdapter.createFromResource(this,
branches, ...
Last is layout, which you are calling, this one is generic from
google. You can create your own in res/layout folder and summon there:
..R.layout.row);
(in case file is named row.xml).
Nice tutorial about layouts is http://commonsware.com/Android/excerpt.pdf

[android-beginners] Re: Question Regarding the Background Menu
You can make your own class which extends LinearLayout and inside of it you
should use this.setBackgroundafter you do this you must add your layout
to your activity. I'm not sure if its corect beaceause i don't know if an
activity can support two layouts but it is a view so it should.
Class MyLayout extends LinearLayou
{
Button button;
Context context;
Public MyLayout(Context context_)
{
context = context_;
button = new Button(context);//you can get context with
getApplicationContext on your activity
LinearLayout.LayouParams button_params = new LinearLayout
LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT);
addView(button,button_params);
SetBackgroundDrawable(...);
}
} after you add this obect to your activity..hope will help you a bit..

[android-beginners] Re: Question
Oh, that id. So I believe you are referring to the function onListItemClick: protected void onListItemClick(ListView l, View v, int position, long id) Android calls this function when the user clicks on a list item, and sets the id value. Under the hood, when the user clicks on a spot in the ListActivity UI, Android takes the y value of the touch point, calculates which row position that corresponds to, and looks up which item id that position corresponds to, and calls onListItemClick(). ListActivity is handy like that. Does that answer your question?

[android-beginners] Re: Question
If I understand your question, you are asking how does Android know you want to launch the NoteEdit activity, right? In the code, you see the line Intent i = new Intent(this, NoteEdit.class); and then a few lines below, startActivityForResult(i, ACTIVITY_EDIT); So variable i knows you intend to do something with the NoteEdit class, and startActivity() uses that information. Does that answer your question?

That link points to a series of blog posts I have about your very issue.
Please forgive the broken formatting, and the examples are from last
summer and so may need some modification to work on the current SDK.
You can get the source code to my original Android book, which has
up-to-date editions of the sample code from the blog posts. Visit
http://commonsware.com/Android/ and click on the Source Code link.

[android-beginners] Re: Question about onSensorChanged Listener
Hi,
I can only speak to question 2, but it seems like you'd want to also
listen for the SENSOR_ACCELEROMETER data, and then look for values
that are above a certain threshold, maybe something like:
if (sensor == SensorManager.SENSOR_ACCELEROMETER) {
float accel_mag = (values[0]*values[0]+values[1]*values[1]+values[2]
*values[2]);
if (accel_mag > (3*GRAVITY_EARTH)*(3*GRAVITY_EARTH)) {
// A force of > 3G was detected.
// Do something.
}
}

In Java, you can name variables whatever you want (given minor
restrictions on punctuation and stuff).
So:
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
and:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
and:
public void onCreate(Bundle quitWorryingAboutTheName) {
super.onCreate(quitWorryingAboutTheName);
are all the same thing.
The name originally was "icicle" because onSaveInstanceState() used to
be called onFreeze().

There's any number of ways to skin the proverbial cat for the layout you want, such as: -- Use a RelativeLayout -- Stick with your LinearLayout and use layout_weight to control the percentage of space taken up by your BoardView and the other widgets -- Move your other widgets to the top, so they get space first, then let the BoardView take up all remaining room -- Mark Murphy (a Commons Guy) http://commonsware.com _The Busy Coder's Guide to Android Development_ Version 1.4 Published! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.

[android-beginners] Re: question about layout.xml and View class
Thanks again for your reply, so it's the same problem I had earlier.
So how is the LunarLander Text being displayed? I tried the same
thing it does, with setTextView(), but mine still isn't being
displayed. Does it have anything to do with the enclosing Layouts,
the FrameLayout as the parent of LunarView and RelativeLayout as the
parent of the TextView? I don't understand why the layout xml is even
used this way, why not just programmatically set the LunarView with
setContentView(new LunarView()) - (yes I know it doesn't have a
default constructor, but couldn't you add one?) Soo confused...
Here's my latest:
main Activity:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.board_layout);
mBoardView = (BoardView) findViewById(R.id.board);
// give the LunarView a handle to the TextView used for
messages
mBoardView.setTextView((TextView)
findViewById(R.id.InfoText));
}
public class BoardView extends SurfaceView {
private TextView mStatusText;
public BoardView(Context context, AttributeSet attrs) {
super(context, attrs);
}
@Override
protected void onSizeChanged(int w, int h, int oldw, int oldh) {
super.onSizeChanged(w, h, oldw, oldh);
mStatusText.setText("width : " + w + ", height : " + h);
}
public void setTextView(TextView textView) {
mStatusText = textView;
}
}

if you write google map app using javascript
you can just put the js/html code into asset folder
then use this code :
WebView wv = new WebView( this );
wv.getSettings().setJavaScriptEnabled(true);
wv.loadUrl("file:///android_asset/map.js");
setContentView( wv );

[android-beginners] Re: question on getSelectedItemId function
thank you for reply! :-)
If I change the _id that is default field's name to other, the program
will throw an exception
It means that I must have a field named _id in the data table, is
right?
can I change the name of id field?

Hello All!I just do the exercise 2 in tutorial document, and I have a question in the onMenuItemSelected function. @Override public boolean onMenuItemSelected(int featureId, Item item) { switch(item.getId()) { case INSERT_ID: createNote(); return true; case DELETE_ID: mDbHelper.deleteNote(getListView().getSelectedItemId()); fillData(); return true;
} return super.onMenuItemSelected(featureId, item); } when I delete the note,the code will call getSelectedItemId() to get the id of the row. But I don't specify the the "id" field in fillData(). only the "text1" field was passed to the Constructor of SimpleCursorAdapter, how can the getSelectedItemId function to get the id? SimpleCursorAdapter will automatic add the id field? Somebody know why? Thanks! private void fillData() { // Get all of the rows from the database and create the item list mNotesCursor = mDbHelper.fetchAllNotes(); startManagingCursor(mNotesCursor);
// Create an array to specify the fields we want to display in the list (only TITLE) String[] from = new String[]{NotesDbAdapter.KEY_TITLE}; // and an array of the fields we want to bind those fields to (in this case just text1) int[] to = new int[]{R.id.text1}; // Now create a simple cursor adapter and set it to display SimpleCursorAdapter notes = new SimpleCursorAdapter(this, R.layout.notes_row, mNotesCursor, from, to);
setListAdapter(notes); }
