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?
How can I draw a shape (e.g. circle, rectange) that has different stroke and fill colors? Eg. A circle with green perimeter, but black inner fill.

View 3 Replies View RelatedI 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?
One of the task of we are working on is to enable the Android Contact sorting by stroke for LOCALE zh_TW. It's very easy to enable the contact sorting by Pinyin for zh_CN, but when I take the same method to enable sorting stroke for zh_TW, the sorting result is either sorted by UNICODDE or PinYin. It's very strange. I have investigated the related code located in android_pkgs/external/icu4c/xxx and tried many options but failed to find a wayout. Is there anybody familiar with icu4c or have ever done some work on this topic? Here I'd like to append the steps (mainly on the location android_pkgs/external/icu4c/) I did as reference:
a. append zh_TW into product locales;
b. append the zh_TW support into icu4c/stubdata/Android.mk
c. taking the cfg-us as example, create a folder cfg-us-zh and append zh_xx related 'zh_xxx.res' files;
d. ./helper.sh us-zh will generate a updated icudt38l-us-zh.dat;
e. recompile Android to launch emulator -EOM-
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..........
View 1 Replies View RelatedI have a GestureOverlayView over the top of a TextView. The TextView has Linkify.addLinks(tv, Linkify.ALL) called on it.
If you click on an URL in the TextView the following exception is thrown Running 2.2 (apparently a pre-release version)

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.
I am trying to add the GestureOverlayView to this and it just isn't working. Finally hacked to where it doesn't crash but this is what i have
CODE:..........
The onGesturePerformed is never called. Their example has the GestureOverlay in the xml, I am not using that, my activity is simple:
CODE:................
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 am creating a button programmatically. It is rounded and has a gradient background, and works fine and looks nice, but I couldn't do two things I wanted:
Set a 1 pixel stroke with a given color. I tried getPaint().setStroke(), but couldn't figure how to set the stroke color. How should I do it?
Align the gradient to the bottom of the button, no matter what height it has. Is this possible?
For reference, this is the code I'm using:

View 2 Replies View RelatedUsing the 1.5 SDK. I have an application with a TabActivity and when I change from one tab with edit fields to another that does not need any user input I would like the virtual keyboard to be hidden. I've tried setting android:windowSoftInputMode="stateAlwaysHidden" on the manifest for the activity that doesn't need user input but it didn't work (maybe because the activity is triggered by a TabActivity).
I've found the method hideSoftInputMethod(IBinder, int) in the InputMethodManager class but I don't know how to get the IBinder object that this method needs.
How do I get that IBinder object? Are there other ways to hide the soft keyboard?
It would be even better if I could make the soft keyboard automatically hide when an EditText loses focus.

I have compiled and signed my android app using the Export Wizard, as described here in the section 'Compile and sign with Eclipse ADT'. I would like to backup the keystore and have it handy for future app updates, but I can't figure out for the life of me where the keystore is saved. I of course can use Eclipse to go through the process, but if something happens to my computer I'll be pretty screwed.
