[android-developers] Margins acting wierd
Hello! I have a question about margins. From what I noticed if a RelativeLayout (and probably not only) doesn't know it's size at measurement time, some child margins are ignored. In my case it's the bottom margin of the last child, above the bottom border of the RelativeLayout when the height of the layout is WRAP_CONTENT / I don't place the layout between some fixed vertical limits. Why is this happening? If I ask explicitly for a margin it should also be included in the parent's WRAP_CONTENT specification when measuring or maybe taken somehow into account.

[android-developers] Fullscreen IME problem
Hello! I have some problems with custom editable views on devices that don't poses a hardware keyboard. Setting the device in landscape mode enables the fullscreen IME to show up. This one covers my custom view but instead provides it's on view on the top of the screen for preview (?). It initially contains the hint assigned in the EditorInfo class. Using an EditableInputConnection + EditText enables the preview to synchronize with what I type on the keyboard. Using my custom view it doesn't and all I can see is just the hint text. However the key presses are recorded by my custom view. I looked through the sources of EditText and EditableInputConnection but I couldn't find anything that suggests how to make the preview to work. Any type of guidance would be really helpful. As I stated in my previous posts I can't use the TextView widgets and solving this is a must :(.

[android-developers] Re: Fullscreen IME problem
Fixed :). I read the doc in http://developer.android.com/reference/android/inputmethodservice/InputMethodService.html . I had to also implement the getExtractedText method.

[android-developers] Architecture dilema
Hello! This may sound a little silly. Let's say I want to build a game with a menu, an options screen, a form screen (for the user to insert some data) and the game screen. The usual approach would be to have an activity for each case (correct me if I'm wrong). What if I do another thing... and code four views for each case and swap them using setContentView() in the same activity? Suppose that I'll override the onSaveInstanceState() to save the state of the views in all the four cases. What is the disadvantage in this approach besides having a huge activity that I'm sure it gets closed every time the system is low in memory? I haven't tested it yet, but I didn't find anything in the docs that could stop this approach to work. The reasons for avoiding the usual implementation is that I need to convert an application from J2ME and having multiple activities raises some difficulties in the porting process.

[android-developers] setSoftInputMode() and addFlags()
Hello!
I've noticed some incompatibility between these two functions.
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.getWindow().addFlags
(WindowManager.LayoutParams.FLAG_FULLSCREEN);
this.getWindow().setSoftInputMode
(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);
.
}
Enabling the fullscreen flag seems to disable the soft input adjust
mode. I looked through the source code of the two functions but I
coulnd't find anything that might cause this.
Any suggestions?
Thanks!

[android-developers] Re: setSoftInputMode() and addFlags()
If I think better, maybe that's the way it should act. The FULL_SCREEN flag makes my window to cover the entire screen so basically it can't be shrinked. A workaround to my problem would be a solution to how to hide the status bar besides the FULL_SCREEN flag.

[android-developers] Displaying virtual keyboard
Hello!
I need help with showing the integrated virtual keyboard on-screen. I
extended a View class and I implemented these two methods (most of it
is just stub code; for now I only want to display the keyboard):
@Override
public InputConnection onCreateInputConnection (EditorInfo outAttrs)
{
BaseInputConnection fic = new BaseInputConnection(this, true);
outAttrs.actionLabel = null;
outAttrs.hintText = Insert the test text;
outAttrs.initialCapsMode = 0;
outAttrs.initialSelEnd = outAttrs.initialSelStart = -1;
outAttrs.label = Test text;
outAttrs.inputType = InputType.TYPE_CLASS_NUMBER |
InputType.TYPE_NUMBER_FLAG_DECIMAL;
outAttrs.imeOptions = EditorInfo.IME_ACTION_DONE;
return fic;
}
@Override
public boolean onCheckIsTextEditor() {
return true;
}
In the onCreate method of my activity I have :
InputMethodManager imm = (InputMethodManager)this.getSystemService
(Context.INPUT_METHOD_SERVICE);
imm.showInputMethodPicker();
imm.showSoftInput(editor, InputMethodManager.SHOW_FORCED);
Where editor is an instance of my View. I noticed in the debugger that
my onCreateInputConnection() is executed but after that the keyboard
is not displayed on the screen.
Using the TextView widtget and it's subclasses is not an option.
Thank you!

[android-developers] View's Drawable.Callback
Hello! I have a small curiosity. How does a generic View use the Drawable.Callback interface? Only for the background? This question aroused from the need to make a more special animation (neither tween nor frame) that should be drawn inside a View. I did the following: 1. I made a class that extended Drawable and implemented Runnable. In run() I placed my animation logic. 2. I overridden scheduleDrawable() and invalidateDrawable() methods in a View class so that schedule would postDelayed the Runnable defined above and invalidate would invalidate the view where the animation should modify the window. I also set my View class to be Callback for the Drawable. 3. In the draw() method of Drawable I used scheduleSelf with a certain delay to animate the Drawable. It works, but I don't understand why if in my implementation scheduleDrawable() I call super.scheduleDrawable() on the first line the postDelayed function doesn't work anymore (and neither the animation). So to resume my questions: Is it ok what I did and what is the default implementation of Drawable.Callback in a View?

[android-developers] PopupWindow animation
Hello! I have some issues with making PopupWindows animate when showing. The setAnimationStyle takes parameter a resource ID to what exactly? I took a look through the android resources and built my own animation style using the values/styles.xml as an example. My styles.xml file: resources style name=Animation parent=android:Animation /style style name=Animation.Popup item name=android:windowEnterAnimation@anim/popup_in/ item item name=android:windowExitAnimation@anim/popup_out/ item /style /resources where popup_* looks like this: scale xmlns:android=http://schemas.android.com/apk/res/android; android:fromXScale=0.0 android:toXScale=1.0 android:fromYScale=0.0 android:toYScale=1.0 android:pivotX=50% android:pivotY=50% android:duration=1000 / Then I call popupWindowObject.setAnimationStyle (R.style.Animation_Popup). How am I wrong? A solution to my problem would be very helpful as it would really ease my application development process (otherwise I'll need to find a solution to simulate a PopupWindow with scale effect).

[android-developers] RelativeLayout question
Hello! I would like to build a layout with this structure (I used buttons only as an example in the XML file): BCCD BCCD BCCD BCCD BCCD Where A = Button01, B = Button02, D=Button03 and C is a ScrollView/ another layout. The XML is the following: ?xml version=1.0 encoding=utf-8? RelativeLayout android:id=@+id/RelativeLayout01 android:layout_width=fill_parent android:layout_height=fill_parent xmlns:android=http://schemas.android.com/apk/res/android; Button android:text=Button01 android:id=@+id/Button01 android:layout_height=wrap_content android:layout_alignParentTop=true android:layout_width=fill_parent/Button ScrollView android:id=@+id/ScrollView01 android:layout_height=fill_parent android:layout_below=@+id/ Button01 android:layout_alignParentBottom=true android:layout_toLeftOf=@+id/Button03 android:layout_toRightOf=@+id/ Button02 android:layout_width=wrap_content Button android:text=Button04 android:id=@+id/Button04 android:layout_width=wrap_content android:layout_height=wrap_content/Button /ScrollView Button android:layout_width=wrap_content android:id=@+id/ Button03 android:text=Button03 android:layout_height=fill_parent android:layout_alignParentBottom=true android:layout_below=@+id/ Button01 android:layout_toRightOf=@+id/ScrollView01 android:layout_alignParentRight=true/Button Button android:layout_width=wrap_content android:id=@+id/ Button02 android:text=Button02 android:layout_height=fill_parent android:layout_alignParentBottom=true android:layout_below=@+id/ Button01 android:layout_toLeftOf=@+id/ScrollView01 android:layout_alignParentLeft=true/Button /RelativeLayout The problem is that Button03 fills all the space under the Button01, even though the layout_width of the ScrollView is fill_parent (I'm not sure if this value is correctly chosen). I tried to set up the relations between the views as exactly as possible. Where am I wrong?

[android-developers] ContentProvider questions
I have some questions about how the ContentProvider works behind the scenes. 1. The ContentProvider class is registered in the kernel when the application is installed and then what? Or how do the other applications exactly manage to access the application data? 2. When is actually onCreate called? The documentation is pretty vague... 3. What happens if two applications register the same provider class? (I have more applications that must communicate between eachother. The content provider must be registered, of course, along with the first application installed on the system. The problem here is that I don't know which one will be, so I want to deliver the ContentProvider with all the applications) Thanks in advance. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.
