I have small ViewGroup somewhere in the middle of the screen. this ViewGroup contains some Views that i'd like to animate.
now this ViewGroup in dispatchDraw() method manages any child Views animations, clipping them to ViewGroup's bounds.
my question is whether it is possible not to clip them to ViewGroup's bounds?

I don't know why this is generating an ArrayOutOfBoundsException! It's likely I've overlooked something because I'm so tired but if someone could tell me what is wrong I'd appreciate it. Code...

View 1 Replies View RelatedI'm trying to draw some large circles on the canvas which are partly offscreen, then use animation to rotate them in be fully visible. My circles successfully rotate in, but when they come into view they're clipped at the place that was the screen edge when they were originally drawn. Is there any way to prevent this? I guess my larger question is how can you draw elements beyond the edges of the screen and then animate them into view?
View 2 Replies View RelatedMy android app draws a chart on a Canvas. It works fine in the simulator. On a real device the chart is clipped to the left 1/5 of the screen. I've tried:
canvas.clipRect(0, 0, canvas.getWidth(), canvas.getHeight(), Region.Op.REPLACE);
to clear the clipping. Am I missing something? Does layering have anything to do with this?
I have a view in a fragment. This fragment is within a FrameLayout. I want to animate this view moving outside the fragment borders. However, the view always get clipped when crossing the border. I have tried by setting "android:clipChildren='false'" and android:clipToPadding="false" to everything, but I can't get it to work.
View 2 Replies View RelatedI wanted to create an gallery with images.The images within the gallery should be zoomable and pannable. I could able to pinch-zoom an image but could not able to set zoom limitand prevent the image from being panned off the screen. I used the following code to zoom an image:http://code.google.com/p/4chan-image browser/source/browse/src/se/robertfoss/MultiTouch/TouchImageView.javaspec=svnd3e623ddeb6f9e97d9eba2c7aaa7c4567a3822b5&r=d3e623ddeb6f9e97d9eba2c7aaa7c4567a3822b5 First approach : I used TouchImageView to supply images to gallery, this allows me to pinch zoom but can't scroll the gallery. i.e I cant differentiate between 'single tab event' and 'tab to scroll event'
View 1 Replies View RelatedI am having some trouble working with the SQLite database. I am able to create the database, add to it, and delete from it with no problem by following the Notepad examples, but I am trying to avoid duplicates and therefore want to check to see if an entry exists already.
Below is the code I have for testing to see if a game exists. I get the correct Log message of "No Games" when there are no games, as well as the correct value for column from getColumnIndex which is proven to me by the log printout telling me that column = 1.
The error message that I receive if I don't catch the exception says "Caused by android.database.CursorIndexOutOfBoundsException: Index -1 requested, with a size of 1
Where is Index -1 being requested if my call to getColumnIndex is returning 1? Code...
I was wondering if there was any way (I'm somewhat a newbie at Java) to get the MapBounds of a Google MapView on Android.
Just to clarify, here's what I'd like to do.
Calculate the maximum and minimum long and lat whenever the map is moved, or zoomed and display those values in a Toast.
Is there any possible way to do this - or am I in over my head?
I'm having a problem with floating windows. My activity has an AutoCompleteTextView text in a floating window positioned at the top of the display. If enough text is entered to make the drop down appear it will be initially clipped to the bottom edge of the window. If you click on the drop down it appears unclipped.
I've stripped my activity down to a test program and put a copy here:

In summary, the main activity just inflates a view and positions it at the top of the display: Code...
I have a plain vanilla layout:
<ScrollView>
<TableLayout>
<TableRow>
but the content gets clipped by the ScrollViews scrollbar.
This link illustrates the issue:

How to avoid content clipped by ScrollView scrollbar ?
Edit: Adding android:layout_marginRight="5dip" on ScrollView leaves ugly gap on righthand side of emulator screen. See below.
The following function is giving me an out of bounds exception...
public void count(){
SQLiteDatabase db = table.getWritableDatabase();
String count = "SELECT count(*) FROM table";
Cursor mcursor = db.rawQuery(count, null);
int icount = mcursor.getInt(0);
System.out.println("NUMBER IN DB: " + icount);}
It's meant to return the number of rows in the database. Anybody know whats wrong? am I perhaps doing this task the wrong way?
I've got a button with italics text in an app widget and the last letter gets clipped when I set the width to wrap_content. It doesn't get clipped with fill_parent, but then that messes up the selection order.
Things I've tried: - space after my text - seems to get trimmed off automatically - layout_marginRight - paddingRight
Anybody know what's going on here? Is this a bug?
Is there some setting that I should know about to display web pages correctly? Some sites will be all squished on the screen ( multiple panels will be overlapped )
Others have the sides of the screen cut off so that the scroll bar doesn't show up.
Changing the display resolution doesn't seem to help either.
( This is when viewing full pages, not mobile pages )
How to use viewGroup in android
View 3 Replies View RelatedCan you please tell me how can I setHeight for a ViewGroup? I see there is a layout(l,t,r,b);
But that is different form setHeight(), since I don't know where should be the top/bottom of the viewGroup. I need to set the height of the ViewGroup and return that to ListAdapter.
I am able to get a GLSurfaceView to have a transparent background with:
CODE:............
when I set the Activity's window background to transparent and the GLSurfaceView is the contentView of the Activity.
But, let's say my GLSurfaceview is parented by a ViewGroup and I want GLSurfaceView bg to be transparent to see the Viewgroup's background - I am not able to do so with the code above. Is this a limitation or am I missing something?
How can one use a GLSurfaceView similar to a ViewGroup, in the sense of adding Views(CustomViews) over it? Is there any means to make the GLSurfaceView be the canvas on which the view draws its contents?

I have the following structure defined in an xml layout file.

TagLayout is a class that extends ViewGroup, and basically holds a bunch of buttons with text (a custom object that act as tags, but that's neither here or there).
The problem is that when there are too many buttons, the view no longer scrolls. I can confirm that I am adding tags but I can't see anything.
If I wrap the above within a ScrollView, the layout never renders. I tried adding the attributes android:isScrollContainer and android:scrollbars, but that doesn't change anything. Is there something I'm missing here?
I should also add that TagLayout is overriding the onMeasure() event. I guess I need to implement a scrolling mechanism there...?
I have a custom ViewGroup that I wrote, and have been able to use it to lay out child elements in code just fine. However, now I'd like to be able to use it for layout in XML. I would also like to be able to add some custom attributes to the XML file to better control my layout. How do I set up, both in XML and in code, a set of custom attributes? Bonus if it can be used with the built in designer in Eclipse.

In my custom ViewGroup, I am returning false after handling the MotionEvent.ACTION_DOWN event.
According to the javadoc: For as long as you return false from this function, each following event (up to and including the final up) will be delivered first here and then to the target's onTouchEvent().
However, I notice that all subsequent events ( MotionEvent.ACTION_MOVE and MotionEvent.ACTION_UP) are only delivered to my #onTouchEvent method. In #onTouchEvent , I always return true.
What could possibly be my bug? I am running on Android 1.5r2 SDK.
