[android-developers] Positioning/Layout of the Input Method / Soft Keyboard
Hi everyone, For an Android 1.5 device I need to implement a new Soft Input (Soft Keyboard) that is not located at either side of the Screen but rather at a corner. I have the layout ready but I can’t get the InputMethodManager to locate my input Method View to be displayed before the Activity without resizing it and positioning it at the corner. What I have done: - I implemented my own Soft Keyboard using the Soft Keyboard Sample from the Android 1.5 SDK. The View used to display the keyboard now holds my own layout. - My SoftKeyboard class (derived from InputMethod) sets the layout to WRAP_CONTENT for width and height. onEvaluateFullscreenMode() always returns false since I don’t want / need id. The problem is, that my Soft Keyboard is now located within the center of the Screen rather than at one corner and the Actvity scrolls down when I reach the height of my Soft Keyboard although it would be displayed correctly besides it. I hope I made myself clear because, unfortunately, I can’t post any codes or screenshots here for confidentiality reasons. Thank you all for your help, it is greatly appreciated.

[android-developers] Re: How to draw a particular part of a view
Hi,
Another approach would be to cache the visible area and only update/
replace the area you want to change from within a different method.
Some example code stubs.
Call the drawMe method whenever you want to replace the Image at the
given location.
You can also provide a Rect to position the Bitmap within the buffer
and call incalidte(dirtyRect) to improve performance.
Please let me know how it worked out for you.
Bitmap mBuffer;
Canvas mCanvas;
public TestView(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);
mBuffer = Bitmap.createBitmap(w,h,Config.ARGB_);
mCanvas = new Canvas(mBuffer);
}
@Override
protected void onDraw(Canvas canvas)
{
super.onDraw(canvas);
if (mBuffer!=null)
canvas.drawBitmap(mBuffer, 0,0,null);
}
public void drawMe(int dx, int dy, Bitmap bm)
{
if (mCanvas!=null)
mCanvas.drawBitmap(bm,dx,dy,null);
invalidate();
}

Looking at your code, you're drawing the bitmap at the top-left of the
canvas (i.e. canvas.drawBitmap(bitmap, 0, 0 ...). Presumably, you're
precalculating where the bitmap needs to be drawn (it's top-left
coordinate) and using those values in the drawBitmap() call?
The onDraw method will only draw what you tell it to. So, what I
presume is happening is that you're asking it to first render this:
1 0 0
0 0 0
0 0 0
which it does, then you ask it to render the bitmap at (I'm assuming
that each '1' is a single bitmap):
0 0 0
0 1 0
0 0 0
The problem is, is that you've not told it about the first bitmap (at
the top-left corner), so it doesn't bother drawing that and just
renders the bitmap in the middle.
Thus, to fix this, you need to be able to keep a track of all the
bitmaps that you want to draw, and where they're to be drawn.

[android-developers] WebView remove entry from History
Hi all, I would like to know if there is a way to remove a specific entry – currently the url displayed – from the WebView history. I need this to do the following – maybe you know a workaround. I have a content provider that shows some HTML text within a webview. The Text can contain some links that may or may not lead to another entry provided by my provider. If the load of a link fails codeWebViewClient.onReceivedError/code I would like to load a different URL and remove the failed url from the history stack. This is nesseccary for the back navigation, I would not want the failing URL to show up again. Any Ideas?

[android-developers] Re: littele sqlite help
Hi Jags,
I am not sure if this is quite what you need but you could try this.
1.Do not use the DateTime Data Type within SQLite, since in my
experience this tends to be very slow. Store the System Time
codeSystem.currentTimeMillis()/code instead.
2.Use the Calendar to define the Date you want and the date after that
3.as the selection (WHERE statement) within your query, try something
like
date = day.getTimeInMillis AND date tomorrow.getTimeInMillis
This will only work if you need the specific date of a month and not
for every 14th .
Hope this helps
Regards Aracos

[android-developers] Re: Back Navigation to defined Activity
Hi Marco Nelissen, thanks for the quick response. The code I posted before is implemented within a base Activity within my test project. The other Activities are derived from this one. The only difference is, they set a different title. The problem was, that the other activities remain on the stack and when I use the back navigation, they are displayed instead of closing the application. The strangest thing happened this morning – as I tested it again to confirm this post, it worked. :-) Don't ask me why but it did. So, thanks again but the problem solved itself.

I would like to have a Menu – Button, called Home, that goes back to

if I press the back button afterwords, the application would close.
I tried calling the Activity with the intent flag
'FLAG_ACTIVITY_CLEAR_TOP' but it does not seem to work.

[android-developers] Back navigation for database stored web pages
Greetings all,
I have a problem with the Back navigation within my web-view.
Here is what I would like to have:
On the device there is a database containing some web-pages. The User
is able to search the content of the database and view the stored
pages. Those pages contain some links.
If the user clicks on one of those links the click is intercepted. If
the reference set within this link is also part of the database, the
stored content is displayed, otherwise a remote URL is loaded.
This works great so far, but the problem I have is, that when I want
to do a back navigation, always the address for my remote location is
displayed and the method for searching the local database is not
shown.
The data from my content provider is displayed with the method:
code
public void showContent(ByteArrayOutputStream content, String title)
{
if (activity!=null)
activity.setTitle(URLDecoder.decode(title));
// loadData(content.toString(), MIME_TYPE, DEFAULT_ENCODING);
loadDataWithBaseURL(BASE_URL + title, content.toString(),
MIME_TYPE,
DEFAULT_ENCODING, REMOTE_URL + title);
}
/code
I implemented my own WebViewClient and overloaded the method '
shouldOverrideUrlLoading' to intercepted the loading of the requested
URL.
There I parse the URL and – call 'showContent' of my WebView to
displayByteArrayOutputStream stored within my database, otherwise I
load the the URL directly by calling 'loadUrl' of the WebView.
On back navigation, the method shouldOverrideUrlLoading is not called
or the URL is formated differently so I could not read the correct
data from the database.
If needed, I can provide a test-application that shows what I mean,
but I hope this will suffice.
Thanks for your help beforehand,
Aracos

[android-developers] Re: TabActivity - OnClickListener not working
Thanks for your Response. am I reading this right, I have to rewrite the complete TabWidget just to get the event when clicking on the currently active element or is there a way to get the adapter responsible for the tabs and add the code you posted? Or am I getting it all wrong and should use a different approch for my purposes? So, here is what I need. I have a List view containing different elements. I want to display that list within different Tabs display the same list sorted by defined Values. This works so far. The user can switch between the different views by selecting the Tab. If the current displayed tab is clicked, the sort order (ascending/ descending) of the current view is changed. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.
