Android :: Enable Fingerpainting Not Only With Finger Touch
Nov 11, 2009
I was checking the possibility to allow painting on the screen of a surface (i.e. API demo Fingerpainting example), however when I checked it, this technic apparently only allows painting with the tip of your finger, if you try to use any other object (pencil, thick pen, etc.) it does not draw anything on the surface. Am I missing something here? Is there a way to allow other objects to draw things on a surface? Is this achievable and how should I proceed?

In the Android API examples there is a Snake game. This game uses a class called SnakeView, which inherits from TileView.
I am doing something very similar to this. I am inheriting from TileView to create a class (SkyView), which will become a square board for a board game (similar to the board for Checkers).
However, I would like for my game board to be 400x400 pixels in size, which will be bigger than the screens of some Android devices (such as the G1). And I would like for the user to be able to freely scroll and drag the board around with their finger (both horizontal and vertical scrolling/dragging).
Can someone please point me in the correct direction for implementing this? The board must be no smaller than 400x400px in size. And however much of the board that can be displayed at once on the screen, should be displayed at once.
Should I wrap my SkyView widget in an AbsoluteLayout and use Scrollbars? If so, what Scrollbar properties to I need to use? I played around with Scrollbars in both directions but couldn't get it to work. Is there another view layout I should put it inside? Code examples would be nice! Thanks for the help. I am at a loss with this one.

I have a problem which is disable and enable scrollView by code. This is my layout which includes header, footer and scrollview. The scrollview contain imageView and MapView. I used scrollview to scroll image and MapView because height total of their larger than height of screen. I want to disable scrollview if I touch map and move in the map. And it is enable when I touch ImageView. So, I will listen even touch and move in the map to enable and disable scrollview.But I try to use setEnable and setHorizontalScrollBarEnabled,setVerticalScrollBar Enabled method to do it but not success.
PHP Code:
<RelativeLayout android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@color/white"
android:orientation="vertical"> <!-- Header --> <RelativeLayout android:id="@+id
[Code]....

I would like to get access to the area covered by a finger for each touch event on an Android.Every touch event will result in a coordinate pair X and Y independent of how big the finger and consequently the touch area is that triggered the event. I was wondering if there is a way to get the area data which triggered the touch event e.g. size or coordinates NOT

I just read about how the Nexus one doesn't have multi-touch enabled, even though it has the capability. The Moment has the capability for it too, but doesn't have it enabled either. Anyone happen to know why the phone makers bother spending extra money on multi-touch screens only to not enable it?

I see in all of the videos that they use their index finger but that just seems so awkward, so I use my thumbs. Has everyone just gotten used to using their index finger or do you use your thumbs as well?

I understand calling onTouchEvent from views to get the location of the last touch as a motion event. How the heck can I tell that a figure is down on the screen and has not been lifted and when the finger is lifted?
For instance there is onKeyDown and onKeyUp for use when you are dealing with keyboard input. So how can I find out when on fingureUp happens?

I have a motion listener to detect finger down, finger drag, and finger up. I start my action at finger down and finish my action at finger up. When the action is finished, I store it in a stack for allowing undo. My problem is that if I don't get a finger up event, I can't finish my action to add it to the stack for undo.
How can I detect that the user's finger has left the screen?
I tried using the emulator to see if getEdgeFlags() ever returned anything useful, and the result was always 0.
Basically, if a finger leaves the screen, then nothing is touching the screen anymore and I would like to detect that as a finger up event. How can I do this?

I can't find a tutorial on Google for my problem. I'm french and i don't find the best "google keywords" for to describe my goal. I decided to ask the question here.
I want to do an animation between views like on the Home or on the Calendar in week mode. I want the switch between the views follows the finger. As I have not released the pressure, I see a part of the current view an a part of the next view.
Currently, I use a AnimatorView and 2 gestures. But the change happens when the pressure is released, and it's not good.
Can someone explain to me how to do or where to find a tutorial that explain? ps : please, don't laugh about my english, it's worst when I speak with my very french accent :P

Is there a way to make highlighting of a row in a listview delayed if the user is simply scrolling the list with their finger? To clarify, when the user puts their finger down to scroll, the intersected row (if any) gets highlighted for a short moment, before it realizes the user is just trying to scroll (then the highlight turns off). It seems like the timeout is too short - iPhone has the same behavior, just seems that the timeout is longer to discern between a real row- select-touch, and just a scroll-touch. Any way to tweak this? You can see the behavior in any of the system apps that have lists..

I purchased the IR overlay from here [URL] I got it working with my mk808b by using an idc fiile, however, it only allows one touch point which means no zoom. On the computer it is multitouch.

I have a ListView. When I click a row Item (which are just TextView instances) I want them to remain hilighted (default orange color). The default behavior is that they flash orange.
Strangely, if I use the key pad (arrow up/down) to move between items, it has the exact behavior I want. Why is the logic different between using the keypad or with finger tapping?

How can I make the ListView immediately stop scrolling on a finger down event? It keeps scrolling if I give it a big swipe and doesn't stop immediately if my finger is pressed down again. Any idea?

I want to create an event to change what my image button looks like, but only when it is being pushed down. So far I have been using an onTouch listener, but that just changes it permanently. I can't find anything like an onKyeUpListener() type of thing for the button.
Does anything like this exist? code...

I am designing a Game and have a large background. The background it a lot bigger than the phone display so the user will only have a small "View" of the background. They will be able to move around by scrolling with their finger.
How do i go about this?

With Android 4.1.1 I had a browser with 1-finger-zoom...will say, I could swipe left or right on the side of the screen to zoom in and out.
Now with 4.1.2 this feature isn't there any longer...
Any way to get this version of browser back? An app to flash or something like that?
