Android :: How Can I Make Page Slide As User Finger On Screen?
Apr 23, 2010
How can i make my page slide as the user slides finger on the screen in android? Any example code? I just require the same feel as it is on my android g-phone's home screen.The screen moves as the finger moves(also includes the elastic effect).
Sometimes when scrolling down on a page (using my finger to scroll) the page will scroll all the way to the bottom of the page with a single flick of the finger. Am I unintentionally doing a specific gesture with my finger that causes this to happen? Or is this just a bug at this point?
My husband was playing around with my Android 4.2 tablet and somehow disabled the slide to next page feature and apparently turned on the voice only (not sure if that is what it is called but it says every movement that you make...back, home, you have 10 new messages, etc....SO annoying). I also have to double click to get to anything...SO annoying. I know I have to get to settings, but for the life of me I cannot figure out how to get to the second page of apps (where the settings is). It won't slide because it's set to double click I guess...no clue!
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'm using a slidingDrawer in my application that has its handler placed at the bottom when in portrait mode. When the user switches to landscape mode (widescreen) I would like to have the handler located on the left. When I change the orientation from vertical to horizontal, the handler is placed on the right.
I'm new to Android development, and I was wondering if anyone knew either how to make Tabs slide, or how to get a similar effect without tabs. I have quite a few tabs in my application, and it does not look good on devices with smaller screens. Or maybe tabs are not what I am looking for. If you don't know what I'm talking about, I'd like to reproduce something similar to Photoshop.com Mobile's effects screen. I know this is possible.
I found event handler: dispatchTouchEvent(MotionEvent) works differently between G1 & emulator when finger is holding on touch screen.
I have a class inherited from RelativeLayout and override public boolean dispatchTouchEvent(MotionEvent event) method. After I touch & hold on the touch screen, in emulator I got MotionEvent.ACTION_DOWN event only. But in G1, I got MotionEvent.ACTION_DOWN first and then MotionEvent.ACTION_MOVE continuously, even if I try my best to hold still my finger tip.
I wonder if this is because there is pressure field in the MotionEvent. Because the blood pressure on finger tip changes continuously with heart beat, so no matter how still my finger is, the pressure value still changes. But I wonder if all kinds of touch screen have pressure factor in their touch event? Will all touch screen driver emit touch event continuously when finger is holding on the screen?
I want to theme my unlock screen. The rom that I am using on my Thunderbolt is Liquidrom 3.1. I am not sure where to start. When I search "How to make slide to unlock widget" I get no matches. From what I have read the CM7 themes work with this rom.
Am developed one login form...here post the username and password from database using webservices...now its redirect to another activity,...that another activity having firstname and lastname for particular loged person details only fetched from database using json web services...
Because more number of users are there in admin side(ajay,krish,hari).... i need who r loged(ajay) in the login page that user(ajay) details only displayed �krish loged means krish details only displayed...but i done the some coding...
I've noticed that I'm getting little tingling shocks to my right index finger whenever I touch the Evo's screen.What's even stranger is that I don't feel the sensation on any other fingers on either hand. Has anyone else had a similar experience with their evo screen and finger feeling little shocks?I'm not imagining this, and I'm wondering why the heck it's just my index finger?!? Maybe it's just more sensitive, but who knows.I would assume that the capacitive touchscreen technology is the culprit. I can live with the slight tingling, I just don't know why it's only on 1 finger!
Anyone else notice when you're on a phone call if you move your finger near the little dot to the left of the verizon logo the screen will turn off? It's annoying when multitasking because that functionality remains regardless of whether the phone call is the active screen or not. If you are watching the Google Navigation screen and you're on a call, move your finger near the little dot next to the verizon logo and the screen turns off.
My nephew was playing with my phone and evidently set a password on the phone to wake it up. He told me the password and I can use it to wake the phone up just fine but I use the slide screen, but now there is both password unlock and the slide screens. I cant figure how to remove the password one
I have got one big problem with the touch input of my Hero. The screen is too sensitive. I can navigate on the screen while my finger is about 5 cm away from it. I can choose what I want, but the screen takes the right horizontal position of my finger, but not the vertical. Anything I want to take, the screen takes the one on the bottom of the screen. The same when I want to write a message or something like this. I choose the "W" or "E", but the screen takes the "X" or "C". If the display goes on Standby and I wake it again, everything is good for a few seconds, but than the same mistake comes again. I already tried to wipe and install a new MCR, but nothing helps. I think, but I am not sure, that I have that problem after I have installed the htc keyboard on android 2.1, as I tried it for a few hours.
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
