do you know if it is possible to keep focus in a widget even if other widgets that are partially visible or not visible at all changes its height size?I wouldn't like to have my screen jump vertically in front of the user because some other widget updated itself to accommodate more data.

I'm trying to realize how the focus and selection in the Gallery widget is doing their job. I'm facing weird situations when trying to update information (TextViews and Spinner) upon a selected item in the Gallery. The focus and selection is lost. So, using the resource gallery_item_background will end in showing the "unselected" background for the current selected image. I have used the .xml that came with the android sdk, and I can't realize how this is happening. I have set setFocusable(false) and setFocusableInTouchMode(false) to all other Views to try out (and true for the Gallery) without any luck.
I have also add 'in-situ' debug, that is, a menu that updates differents widgets when onItemSelected() is called. So I can see while using the application how the background resource is applied. When set to 'no update' the obvious thing happens. None of the widgets are updated with new values, and the background resource works as expected. When set to 'manual update' (an update in the listener that do: .setText() on the textview) does work depending the current View that is showing the TextViews (I have a ViewFlipper that display 2 differents Layout of the TextViews)...............
I'm writing a appwidget and hope to limit a widget can be added only once on homescreen, and for further trying, i hope to show the correct page of homescreen to show the widget, just like native media player widget.

View 1 Replies View RelatedI have made a custom widget, very similar to JTable in Swing. It is not editable, and all data is replaced at once, allowing easy checking for the widest item in each column & custom col sizing at replace time. It is a subclass of LinearLayout, filled with re-usable TableRow Objects, sub-classed directly from View.
TableRow is both Clickable, focusable, & focusable In Touch Mode. TableRow overrides onDraw(Canvas), calling super. It draws the first column in Black with Lt gray underneath. If the TableRow isFocused () , then a filled rectangle is drawn, before the rest of the cols (left or right justified based on data type), and borders. Where do I get the color, orange, to draw the filled rectangle indicating focus? android.R.drawable.list_selector_background seems to be a pointer, value 17301602, not an actual color. Placing any real Color in my code draws things fine. Is this 17301602 transparent or something? Am I doing this wrong, or do I just need to know how to fine the orange?
I loved the camera on the Eris and the Incredible, not only did they have a whole lot more of a crisp high-res detail, the auto-focus absolutely rocked. With my droid x, I can be getting a little artsy and focus on an object with the crosshair but it'll take me 20 tries to get it to lock on, its insane, I know I'm not getting too close to my subject because it will definitely eventually focus on that object if I try over and over and over again. It's not just close ups that I find myself and my buddy with this issue either. macro shooting mode does not help. My buddie's droid X has the same exact behaviors. Eris and incredible just LOCKED ON first try with even very low contrast / detail subjects, on top of that, have a ton better camera GUI when it comes to "click to focus". I know this thing ain't no SLR but, blows me away of how terrible the camera performance is vs. the HTC android based devices. Ihink motorola will fix this? I know this thing ain't no SLR but it just blows me away how the HTC android devices camera performance (except for video) blows the Droid X away.

View 2 Replies View RelatedI have a form that is working fine with the "Next" flow order when using the computer keyboard with emulator (and probably with the keyboard on the G1) but not with the SoftKeyboard with 1.5.Some fields indicate "Next" with this keyboard, some go to the correct field and others don't.Two of the fields are text and they only give a carriage return instead of "Next."My numeric fields give the proper "Next" key. Use of the SoftKeyboard is a little underdocumented so far (if there is a hidden doc online somewhere please provide me a link to it). There are also some added fields under 1.5 that I have asked about previously but received no answer.These appear to have something to do with the Soft Keyboard.Though these can be set programmatically I haven't seen the proper way to set these flags using XML. This field is the one that replaces "Numeric" which deprecated.
View 3 Replies View RelatedHow can we prevent an edittext from getting focus and displaying the soft keyboard. I have an searchbox which should not be focused by default and should have focus only when user clicks on it to enter something. But right now it takes focus and shows the keyoard as soon as I open the activity. Is this a bug or can this be changed to behave in the way we want?
View 2 Replies View RelatedCurrently I have an edittext field that when the user presses enter it does mostly what I want it to, validate an IP Address format and inform the user if it is wrong. How do I make it so when the user presses enter it checks it like it is supposed to be does not enter the newline character?
Here is my code for it.
public boolean onEditorAction(TextView arg0, int arg1, KeyEvent arg2) {
if(validateIPaddress(m_etIPAddress.getText().toString())){
ConfigData.m_IPAddress = m_etIPAddress.getText().toString();
} else { showAlertDialog("Invalid IP Address
Example: 255.255.255.255 0.0.0.0","Error: ");
m_etIPAddress.setText(ConfigData.m_IPAddress);
m_etIPAddress.requestFocus();
} return false;
}
Another problem I have is that in the false condition of the validation, that it will not bring up the soft keyboard to allow the user to reedit that text field. If the user clicks on another edit text the window gives it focus, and allows the user to edit the second text field while still maintaining the 'green outline' around the original edittext.
The EditText still creates a newline. I tried calling that when I create the EditText and it shows the dialog then inserts a newline character at the beginning which is weird because the
m_etIPAddress.setText(ConfigData.m_IPAddress);
Should automatically overwrite anything in that field to the static IP saved within ConfigData. (my settings class) and I think the focus might work, the problem is that after requestFocus, that EditText shows it has focus but is unresponsive. I can click on other EditText's and modify them, while it still shows the focus outline on the IP EditText. If I click on the IP EditText it doesn't actually do anything. Its kind of strange.
I have an Activity that keeps running after the Home button is pressed (naturally) and of-course the focus is in the home screen, and when the running process ends I need to restore the focus on that activity. In more PC expression, I need to maximize the application.

I'm currently getting to grips with Android, playing around with the Lunar Lander sample. I've found that if you navigate away from the app (eg, hit the call button) it will destroy the underlying surface (calling surfaceDestroyed). Navigating back (which will trigger onWindowVisibilityChanged) the app will crash, as it will try to draw to the surface without recreating it. Is there some code I can put in onWindowVisibilityChanged (or anywhere else) that will regenerate the SurfaceView's underlying surface and resume execution nicely? It feels like this should be a simple function call but I can't find anything in the API docs.

My problem is that if I have focus on any of the header ImageButtons then when pressing down with the dpad the list get focus on its 7th row (depending on row height), and not on the first row. I've seen the same behavior on Fring application, under Contacts. I tried by listening for the OnKey event for the KeyEvent.KEYCODE_DPAD_DOWN and triggering a implicit focus on the first item of the list, but I don't know how to do it either.
My app is struggling to take focused shots. Is there a built in facility that sets an auto-focus property on the camera, so it automatically takes clear and focused images. I've noticed that feature in numerous well-known apps such as ShopSavvy, CompareEverywhere, etc. Could you advise on how to achieve that?

I have a listview, and wanted to make some list items to be non-focusable. i.e On pressing the down-arrow key, some items in the middle of the list gets skipped.
I tried the following method. 1. created separate ArrayAdapter class. 2. override getView method. 3. In getView, I called setSelected(false) and also tried setFocusable(false) for some items, but its not working.
The context: I want to have a ListView that wouldn't receive focus (e.g. won't highlight row when user touches it). Yet each row widget has it's own OnClickListener.
Here's what I specify in layout xml:

I have an activity with two edittext controls. I am calling the requestFocus on the second edittext field since by default the focus goes to the first edittext control.

View 1 Replies View RelatedIn my application I have a single EditText together with some TextViews, button and a spinner. My EditText receives focus since it is the only focusable view in this activity, I believe. My EditText shows with an orange border and cursor on the field. Now I would like to remove the focus from this field (I don't want the cursor and border to show). Is there a way to do this? I have been able to focus on the button by doing button.seFocusableInTouchMode() and button.requestFocus(). But this highlights the button and is obviously not what I want.
