With the XML layout shown below, I have some views wrapped in a GestureOverlayView. As shown below, my first row is blended with the second row, as-if the first row is transposed right on top of the second. Now when I take the GestureOverlayView out of the code and leave everything else as-is, my table looks fine - the rows are separate and not on top of each other..........

I have been using some nice tutorials on drawing graphics on my android. I wanted to also add in the cool gesture demo found here:
http://developer.android.com/resources/articles/gestures.html
That takes these lines of code:
CODE:..............
This is fine and dandy yet I realize in my demo i'm trying to build using code from "Playing with Graphics in Android". The demos make sense, everything makes sense but I found out by using: setContentView(new Panel(this));
As is required by the Playing With Graphics tutorials, then the findViewById seems to no longer be valid and returns null. At first I was about to post a stupider question as to why this is happening, a quick test of playing with the setContentView made me realize the cause of findViewById returning null, I just do not know how to remedy this issue. Whats the key I am missing here? I realize that the new Panel is doinking some reference up but I am not sure how to make the connection here.
The: R.id.gestures is defined right int he main.xml as:
CODE:.............
So I did confirm the setContentView(new Panel(this)) is causing the issue. So I know the issue is that I have to figure out how to add the android.gesture.GestureOverlayView to the panel class somehow, I am just not sure how to go about this.
After fighting with this I generally know what I need to do just now how to do it. I think I need either the equivalent of creating a panel in that main.xml OR figuring out how to build whats in main.xml for the gestures in code. I am close because I did this: GestureOverlayView gestures = new GestureOverlayView(this); which gets me a non null gestures now, unfortunately since I am not telling it to fill Parent anywhere I don't think its really showing up, so I am trying hard to figure out layout pa rams. Am I even on the right track?
I am using GestureOverlayView with ViewFlipper, and it takes about one second for the android to recognize my gesture and flip to next view. However, the Android calendar flips almost immediately. I checked the Android calendar code, and it uses GestureDetector. Is there big difference between these two gesture detecting mechanisms?
I am also wondering what's the difference between these two mechanism of detecting gestures. I know GestureOverlayView came out at 1.6, while GestureDetector was in 1.0. But why didn't they just deprecate GestureDetector when GestureOverlayView came out?
I have a ListView with GestureOverlayView, when user swipe left, it mark the ListView Item. It is working perfectly. only thing I don't like to see is when user swipe it display the yellow color stroke line. Is there any way I can make it not to display the Stroke when user perform gesture?

I was informed in a later answer that I have to add the GestureOverlayView I create in code to my view hierarchy, and I am not 100% how to do that. Below is the original question for completeness.
I want my game to be able to recognize gestures. I have this nice SurfaceView class that I do an onDraw to draw my sprites, and I have a thread thats running it to call the onDraw etc .
This all works great.

The onGesturePerformed is never called. Their example has the GestureOverlay in the xml, I am not using that, my activity is simple:

So I am at a bit of a loss of the missing piece of information here, it doesn't call the onGesturePerformed and the nice pretty yellow "you are drawing a gesture" never shows up.
I have an Activity in which I have a TableLayout. I fill the table with TableRows in which I display TextViews. Imagine this as a classical table with text content. After the loop is finished I want to read all the heights in pixels of all the TextView in this table. I do this with getHeight(). The problem I have now is that ALL the values are 0 (zero) pixels. Even though I have text in the TextViews. The odd thing about this is, if I read the height of the exact same TextViews in an OnClickListener () then I do get the real height of the elements. Why is that so? I mean, nothing has changed in the height of those elements in the time between filling the table and firing the OnClickListener(). I really need to be able to get the height of the TextViews right after I filled the table. To get the heights upon a click is too late already for what I want to do.

I'm making a image gallery with infinite vertical and horizontal scrolling. I put images inside a ListView to make a column, and put the ListViews inside a TableRow. However, it seems that child views of TableRow is not selectable and as a result I can't select the images in my ListView (easily). Is there a way to pass the events down to child views of TableRow so they can be selectable?

I have already posted on their developer group but based on everything I've seen I don't expect a reply. I have a strange problem. When I added and adview to my app it imported a bunch of comments that all start with /** Eclipse is acting like it is not a comment. Although it isn't erroring out it has now marked anything starting with R.id as not existing.

View 1 Replies View RelatedI have a simple app that just initiates a wifi scan every two seconds and then logs the results. I am observing some strange behaviour, and was wondering if anyone could shed some light. When I start scanning, if the phone (Nexus One running latest Froyo OTA release) is just sitting on my desk (screen on or off, it doesn't matter), I receive the wifi scan results about 800ms after initiating the scan, fairly consistently. At most, it takes a second and a half to receive the results. However, if I get up and start to walk around the building that I'm in, the time between initiating the scan and receiving the result begins to vary greatly. What is interesting is that I start to see a pattern where it will take about 40 seconds to receive results, then I will get three or four results two seconds apart, then it takes 40 seconds to receive the next set of results, then I get three or four results two seconds apart, etc.
I've tried obtaining a wifilock, both the FULL and SCAN ones, and that doesn't help. Same with a partial wakelock. I've also tried setting up a thread that pings the supplicant every second and reports when it is unreachable, and it appears to always be responsive (ie., I never see the report). I thought that maybe the problem was that I am unable to receive the result of scans when I am switching between base stations (which might happen when I move around), but if I manually switch between two different networks, it does not cause a delay in my scans (ie., I can still get the results with only a one second delay while it's associating with the new network). Anyway, for my application, it would be incredibly useful to get wifi results at a fairly consistent rate, and so I was hoping that someone on this list might have some suggestions as to how I can achieve this.
A customer just notified me that she's experiencing the infamous "app not responding / wait, force close" message during a specific operation. By just waiting enough, the app resumes ok. Now, that specific operation is indeed long and in fact it has been programmed in a background thread, with a progress dialog signaling the wait. I can't reproduce the problem on my development phone - I suppose because it's perhaps faster than the phone of the user. But I can't reproduce the problem either with the emulator, which I suppose is slow enough. Generally speaking, I think I could be able to solve this specific problem with the customer giving me the proper feedback. It's the general issue that hassles me. This part of the application is very good covered by tests at different levels, including automated black-box tests with Robotium that drive the UI as the user would do, and even in "stress mode" (repeating the test multiple times). So I supposed to be very safe in that area and I'm disappointed to discover that it was a false sense of safety. What am I possibly missing? Also, is it possible / does make sense to "slow down" a phone during tests? I was thinking of a service running in background just consuming some CPU cycles to make the phone less responsive.

I need to retrieve the orientation of my phone. At the moment i wrote this :

This code allows me to get the orientation of the phone if i leave the phone on a flat surface and i rotate it over the surface.
What i did not understand is why if i move the phone upwards the value of this.actual_orientation[0] ,which is the rotation on the zed axis as described [here][1], the value increases although there was no rotation.
Did someone know what happens?
Another strange thing..

I tried in the same office(same situation) a compass app that i took from the market and it has the same behaviour of mine..when i moved the phone upwards the value changed consistently..
I tried in the same office(same situation) the i-phone compass and it didn't have that strange behaviour!
Then when i arrived at home i tried both, my application and the compass app of my android phone, and they worked!even if i move upwards the phone the value are stable...
Last night I downloaded antivirus free by droidSecurity inc.I ran a scan and it said I had something suspicious but would not allow me to view any details. Eh lame, I removed the app and jumped into bed.Today I was out driving around and got a warning my internal Phone memory was low. I took a look and it said 150 MB free.so I rebooted the phone and maybe I was being dumb because I thought you could cancel the SIM password and use the device as a PDA with no access to make phone calls.Anyhow I restored my clockwork recovery nandroid backup from a couple of days ago and now things seem better. Phone has 0.9 GB free.Are there any good applications to help manage the available memory on the phone?
View 4 Replies View RelatedI have a strange issue. I am using KSOAP2 to create a soap request to a .net webservice. I do this in a few other places and everything works fine. The webservice basically queries a data base and takes the values from the data reader and creates a string. This string is then returned. When I run the webservice on my local machine(Without using android) it works fine. When I run it from the webserver (still not android) it works fine. When I call it from my phone however the line: String hazards = (String)envelope.getResponse().toString () ; //Get response from .net Web service Simply is filled with anyType{}. Now if I go to the webservice and I manually type in the contents from the database to represent what the string concatenation should be it works perfectly. The line: String hazards = (String)envelope.getResponse().toString(); //Get response from .net Web service Now returns the string value i need. Does anyone have any idea why this is happening or know a better place to ask this question?
View 4 Replies View RelatedI'm trying to get my head around how the vram is used in opengl, specifically when and how to clean it up. The Story So Far. I have a GLSurfaceView into which I set a Renderer implementation (called OpenGLRenderThread). This view is created (manually, by calling "new") in the main Activity of the app. When the onSurfaceCreated method of the OpenGLRenderThread is called, I load a bunch of textures in a fairly standard way: the app runs fine, however when I try to clean up these textures at the end of the "level" (the app is a game. I do the following: On the emulator it works fine, but on the device (HTC Desire, 2.1) I get a GL Error 5572216 I have no idea what this error code is as I can't seem to find any reference to it. I understand that the VRAM references are bound to the thread that created them. Hence they can only be destroyed by the same thread. In my case, this thread is the OpenGLRenderThread (Renderer) during the onSurfaceCreated call.Unfortunately the Renderer interface does not expose an "onSurfaceLost" method, so I created my own. When the Level is complete, my main activity queues a request on the OpenGLRenderThread using the following call to the GLSurfaceView: According to javadoc for queueEvent: "Queue a runnable to be run on the GL rendering thread" Ok fine, so this should mean that the OpenGLRenderThread is performing the call to onSurfaceLost. This method is the one that then calls glDeleteTextures, and produces the error. what am I doing wrong here? I am not destroying the OpenGLRenderThread or the GLSurfaceView at any point (other than game exit) so I'm worried that if I don't explicitly delete the textures my vram will eventually fill up, or worse get into a corrupt state. The only other thing that may be relevant is the use of a ViewFlipper. Because I want to load each level asynchronously I am using a ViewFlipper in the main activity to flip to a loading screen while all the level resources are rebuilt. Hence when the call to glDeleteTextures is made, the GLSurfaceView is not actually visible not sure if this is meaningful or not.
