Android :: Touch Mode Catch Scrolling Direction
Oct 20, 2010
I want to ask that is that possible do in android catch the in the touch mode catch the scrolling direction ? When user touch on the screen left to right, can I catch the change ?
If it is possible which listener can ı use ?
I found some of the methods and listeners but I 'm not sure that therse are represent my requirement .

Scrolling on an Android phone makes sense because it's like you're physically sliding the page upwards. However, now that I'm used to doing that, when I get on my laptop and start to scroll with my touchpad, sometimes I find myself scrolling the wrong direction. On a touchpad you drag downwards to go down on the page, or to slide the page upwards. So it's backwards from the motion you would make on your phone.

Is there an easy to know the direction of scroll (up or down for a vertical list) and the scroll velocity for ListView's?

I'm making an Javascript web app and I can't for the life of me get the touchstart event to fire. I get the touchmove and touchend events no problem. This is a problem because as I see it the best way to distinguish between a tap and a scrolling motion is to zero a counter on the touchstart event, update it at touchmove and then compare it at touchend. I'm doing this so I can do some action at the end of tap but not a scroll. For instance, it would be very confusing if a page opened for an item in a listed after you finished scrolling down that list, but it would be nice to be able to tap on an item to open its page.
This is what I have..
I never see the touchstart alert. If I scroll the touchend will fire and app__touchMoving will have some sort of decent value. On a side note, I've noticed that sometimes the touchend will seem to fire multiple times.
Am I missing something basic here? Plenty of people say that this should work just fine on Android (and iPhone) yet the first listener never seems to fire.
Update: I should mention that I've been testing on a Samsung Galaxy S running Android 2.1.

Actually I'm trying to implement an ontouchlistener into my android (1.5) application. therefore i implemented the "ontouchlistener" into the class, and then i put my code into the: So isn't there a way to catch the touch event before it gets to each of those views?

Just wondering if there is an easier way to simply stop ScrollView from being scrolled via touch inputs? I will programmatically get the ScrollView to scroll to top or bottom.
As a last resort, I guess I will have to inherit from ScrollView and capture all the ontouch events. But wondering if there is an easier way before I take this approach?

As a work around to the issue where a list item isn't focusable if it has a focusable child item (a comment by Romain Guy was that this was intended behavior, for accessibility reasons) I simply filled the listItem with two children, each of which is focusable - There's nowhere to directly touch on the listItem anymore, just it's children.
For the most part this is a useable workaround, effectively invisible to the user, except for one thing- Although you can scroll by swiping without issue, touching to *stop* the scroll no longer works- I imagine because the child item is capturing the touch event and not passing it to the parent listitem, at least while the scroll is in effect.
Is there a known workaround for this? Perhaps someway to "pass the baton" of the touch event back up to the parent listItem, or a way to change my design?
BTW- I know there's some built-in functonality for single/multiple choice listviews (checkbox listviews) - That doesn't actually help in my case. The app is a contact list, and the row children are a relativelayout (populated with contact info) and a clickable phone icon (a one-touch dial for the contact), which needs to be visible or invisible depending on whether the stored contact has a phone number.

i'm rearranging items in the list by dragging the item. I'm in the touch mode and want to scroll view couple of items then i'm on the last/first visiblePosition. Since i'm in the touch mode setSelection is useless. How i can scroll a list in the touch mode. For drag i'm using onTouchEvent , onLayout to change background for the current item + some stuff in adapter to make a swap.

I am quite confused on this is InTouch mode or not for a View. Some of the apps I have seen can accept touch and keyboard requests that the same time but I cannot figure out how they are doing it. This is what happens in my app. Please shed some light on why this happens. If I touch the screen the keyboard is no longer responsive until I ackmoved the TrBall which takes me out of touchmode. I have used apps that seamlessly go from touch and keyboard without the need of moving the trackball.

I've been playing with the data given by the accelerometer,trying to work out how I can gauge a shake from front to back or side to side. This all seems straightforward enough.But I'd love to know the direction of the shake. So, if the user is shaking backwards and forwards, I want to know if the device is moving away from the user, or back towards him/her. I can't find any way of telling this.

I'm trying to create a compass for my application BUT the difference is that, instead of having a line always pointing to north, I want this line to point for a specific point. I've been trying dozens of algorithms and nothing works. I've finally found one that points me exactlly to the point I want. But it doesn't move if I change the position of the device which is my objective. Basically, what I want is that no matter the direction I'm using my device. The line always point me to the point (picLatitude,picLongitude). I understood that for the line to move, I can't use static variables. I need to use the values offered by the onSensorChanged(SensorEvent event). This are the data I have available:
event.values[0]: azimuth, rotation around the Z axis (device in relation to north, 0º) event.values[1]: pitch, rotation around the X axis event.values[2]: roll, rotation around the Y axis mLatitude: device current latitude got from GPS (variable) mLongitude: device current longitude got from GPS (variable) picLatitude: static picture latitude established previously picLongitude: static picture longitude established previously distance: distance in Km from device to the picture calculated previously
And this the formula that works correct, and gives me the correct angle. (But it doesn't use any of the Sensor Data so the line Compass doesn't move):
double dLong = picLongitude - mLongitude; double y = (Math.sin(dLong) *
Math.cos(picLatitude)); double x = (Math.cos(mLatitude) * Math.sin(picLatitude) - Math.sin(mLatitude)*Math.cos(picLatitude)*Math.cos(dLong)); double angleDegreesWrongRange = Math.abs(Math.toDegrees(Math.atan2(y, x))); float angleDegrees = (float) ((angleDegreesWrongRange+360) % 360);
myCompass.updateDirection(angleDegrees);
I got this "bearing" formula from this website: http://www.movable-type.co.uk/scripts/latlong.html. I've try adding, subtracting, the azimuth.. I've tried with the others, seriously at this point I'm just demoralized.

I'm trying to implement something that I don't even know if it's possible. So I have this class which implements a SensorEventListener like this:
private SensorEventListener mySensorEventListener = new SensorEventListener(){
@Override public void onAccuracyChanged(Sensor sensor, int accuracy) {
} @Override public void onSensorChanged(SensorEvent event) {
myCompass.updateDirection((float)event.values[0]); } };
And a class that handles the way the compass looks like this:
public static class compassLook extends View {
private Paint paintPointer = new Paint(Paint.ANTI_ALIAS_FLAG);
private Paint paintCircle = new Paint(Paint.ANTI_ALIAS_FLAG);
private Paint paintLeters = new Paint(Paint.ANTI_ALIAS_FLAG);
private boolean firstDraw; private float direction = 0 ;
public compassLook(Context context) { super(context); init();
} public compassLook(Context context, AttributeSet attrs) { super(context, attrs); init();
} public compassLook(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle); init(); } private void init(){
paintPointer.setStyle(Paint.Style.STROKE); paintPointer.setStrokeWidth(3);
paintPointer.setColor(Color.argb(255, 209, 114, 2)); paintCircle.setStyle(Paint.Style.STROKE);
paintCircle.setStrokeWidth(2); paintCircle.setColor(Color.argb(150, 255, 255, 255));
paintLeters.setStyle(Paint.Style.STROKE); paintLeters.setStrokeWidth(1);
paintLeters.setColor(Color.argb(230, 255, 255, 255)); paintLeters.setTextSize(12);
firstDraw = true; } @Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { setMeasuredDimension(MeasureSpec.getSize(widthMeasureSpec),
MeasureSpec.getSize(heightMeasureSpec)); } @Override protected void onDraw(Canvas canvas) {
int cxCompass = (getMeasuredWidth()/2); int cyCompass = (getMeasuredHeight()/2);
float radiusCompass; if(cxCompass > cyCompass){ radiusCompass = (float) (cyCompass * 0.9);
} else{ radiusCompass = (float) (cxCompass * 0.9);}
canvas.drawCircle(cxCompass-50, cyCompass, radiusCompass, paintCircle);
if(!firstDraw){ // Desenho da linha que aponta canvas.drawLine(cxCompass-50, cyCompass,
(float)(cxCompass-50 + radiusCompass * Math.sin((double)(- direction) * 3.14/180)),
(float)(cyCompass - radiusCompass * Math.cos((double)(-direction) * 3.14/180)),
paintPointer); double mLatitude = (mLocation.getLatitude() / 1E6);
// I get this value from a LM request double mLongitude = (mLocation.getLongitude() / 1E6);
// I get this value from a LM request double picLatitude= Double.parseDouble(picLatitudeString);
// I get this value from a bundle double picLongitude = Double.parseDouble(picLongitudeString);
// I get this value from a bundle float direction = (float)
Math.toDegrees(Math.atan2(picLongitude- mLongitude, picLatitude-mLatitude));
float distancia = (float) (Math.sqrt(Math.pow(mLatitude- picLatitude,
2) + Math.pow(mLongitude-picLongitude,2)))/2;
//Desenho do texto que indica a distancia
canvas.drawText(String.valueOf(distancia) + "Km", cxCompass-30,
cyCompass+20, paintLeters); } } public void updateDirection(float dir)
{ firstDraw = false; direction = dir; invalidate(); } }

My current app flies in a sub activity when you flick-up. Problem is, it flies in horizontally from the right. I want it to fly in vertically from the bottom to match the flick direction. I'm sure this must be an xml property somewhere, but I can't find it. Does someone have a pointer as to how to set this?

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 want to show the direction on the screen that phone is facing.
For example:
0
|- []
|_
South --- North
In the above diagram the phone would display "North". Since the user (the stick with 0 for his head) is holding out the phone (the [] in the diagram) pointing north.
I found this example. I understand what it's doing except it seems to calculate yaw, pitch, roll, and inclination. What are those and how would I use them to simply find which way the phone is pointing?
Also this android documentation mentions X, Y, and Z axises but I don't see anywhere that says how those axises correspond to the phone? Is Z going from the bottom of the phone to the top?

I'm a bit new to Android but after searching on the Market, the web and this forum, I can't seem to find anything like this but I feel like it has to exist (or hopefully will soon). I'm looking for a camera application that can place the current compass direction on the image (and stamp the saved image with the direction). The tilt of the phone would be cool to have, too, but just the compass would be great. I did find an application that shows the compass direction on over top of a feed from the camera ("Reality + Compass" by Udell Enterprises).
I want something just like this, but with the ability to save the image. In case you're wondering, I'd like to use this for bettering the storm spotting community. A problem when people send in images of clouds/storms/tornadoes/etc is that you never know (1) where the picture was taken and (2) in what direction. Ideally GPS location could be added, too, but for now I just want the compass. (Other image services can handle the location part fine, like Twitter for Android/Twitpic.)
(I'm on the HTC Aria, but I can sideload apps now thanks to the new version of HTC Sync.)
