Android :: What Is Meaning Of Boolean Value Returned From Event Handling Method

Sep 20, 2010

In android, most event listener methods return a boolean value. What is that true/false value mean ? what will it result in to the subsequence events ?class MyTouchListener implements OnTouchListener {@Override public boolean onTouch(View v, MotionEvent event) {logView.showEvent(event);return true;}Regarding to the above example, if return true in onTouch method,I found every touch event(DOWN,UP,MOVE,etc) has been captured according to my logView. On the contrary,if return false, onely the DOWN event been captured. So it's seemd that return false will prevent the event to propagate. Am I correct ?Furthermore, in a OnGestureListener, many methods have to return a boolean value too. Do they have the same meaning ?

Android :: Droid Slide Event Callback Method

Nov 12, 2010

I'm having crash reports on Motorola Droid phone which force closes my app when the slide is open or closed. I don't have the phone and can't test it. I was wondering if anyone know what kind of event occurs and if any activity callback method is called for those events. Btw, my app is fixed to portrait mode, and the crash probably happens when the background operation is going on while the progress dialog is in the foreground.

Android :: Boolean Preference - Saving Status Of Checkbox

Oct 6, 2010

I want to have the status of a checkbox be saved into my prefs. I set a listener on the checkbox, and if it is checked I do a prefs.putBoolean("cbstatus", true), and it is it unchecked i do a prefs.putBoolean("cbstatus", false); Trouble is, in my onStart() when I get prefs, my Boolean getcbstatus = prefs.getBoolean("cbstatus", false); will always return a true, regardless of how my listener should have set that status previously.

What am I doing wrong? I have working prefs for other things like spinners, textviews, and edit texts, but what should be the simplest type (a boolean) is giving me a hard time. I've even tried taking out all code related to listeners and pref setting for this checkbox, so that the only code in the entire activity that deals with the checkbox is in the line

Boolean getcbstat = prefs.getBoolean("cbon", false);
if (getcbstat = true) { cb1.setChecked(true);
} else { cb1.setChecked(false);

Since there is no cbon preference (i deleted them all), it should return false by default and the box should be unchecked since. cb1, of course, is the name of my checkbox. Update on the code:

OnClickListener cb = new OnClickListener() {
public void onClick(View v) { if (cb1.isChecked()) {
prefs.putBoolean("cbon", true);
} else { prefs.putBoolean("cbon", false);
} } };
And in the onStart():
Boolean getcbstat = prefs.getBoolean("cbon", false);

Android :: Accuracy Of Location.getAccuracy() GSM And GPS - Exact Meaning?

Jun 16, 2010

As said in the Android Reference, the method getAccuracy() of android.location: "Returns the accuracy of the fix in meters. If hasAccuracy() is false, 0.0 is returned." But what does that mean exactly? The diameter or the radius? The Circular Error Probable (CEP), the 95-percentile or something else? I hope they are of the same type in GPS and GSM positioning. Does somebody know where these information are given into the system? As far as i know, are the GSM coordinates returned by a hidden Google API over a Web Service. So no chance to see an exact calculation. But where is the Accuracy of GPS calculated. I thought the GPS receiver only returns a dimensionless DOP value. And with Android 1.5 its not posible to read the NMEA sentences directly.

Android :: Broken Gallery View? Using Gallery Set Selection (int Position / Boolean Animate)

Feb 6, 2009

I'm trying to set the selection of a Gallery in code. I would like to have the Gallery smoothly roll down a few items over the duration of a second or two. At frist glance, it appears that two members would to the trick:Gallery.setAnimationDuration(int animationDurationMillis); Gallery.setSelection(int position, boolean animate); It turns out that the setAnimationDuration only seems to affect the rubber-bandy "return-to-center" effect of the Gallery. In other words, when a gallery comes to rest after a fling, and a gallery item is off center, the animationDurationMillis is used to control the duration of the Gallery centering up the item. However, the value seems to have no effect on the setSelection. No matter what value is set with setAnimationDuration, the Gallery seems to render about 2 or 3 frames when flying between items 1 and 10 for example. Is this working as designed? Does anyone know a trick or workaround that would let me properly animate setSelection? I'd be especially grateful if we could do it with an "Ease Out" effect.

Android :: Draw 9 Patch Tool - What Is Meaning Of Black Lines Outside Figure

Nov 20, 2010

I tried enough to find in google & android this question. Also did several trials & errors, but couldn't get this question. was learning Android's "Draw Nine Patch" images. One basic I know is that, whatever image you process must be in .png format (if it's already in .9.png then it will be ignored by tool). However, couldn't understand what it literally means by "stretchable patches" ? what exactly happens when you draw black dots outside the .png image ? (preview pane shows changes happening, but I am unclear on how it makes those)When I draw black dots in left/top sides of image it shows some changes in preview; but why isn't there any effect when you do the same on right/bottom side of the image ? why this tool is used primarily for background, when we try to process on the image itself ?i am trying to modify a simple button.png (given in android sdk). Whenever I use this tool & draw black lines, it reduces the size of the image instead of 'stretching' it! Why ?What is the significance of options given below like, "show lock", "show content", "Patch scale" and so on ?I apologize for asking so many questions, but in Android online docs they haven't explained well for novice. If someone can answer these, it will become ready reference for all the begineers who search this forum.

Android :: Should I Use "synchronized" For A Boolean Variable?

Oct 18, 2010

I use a boolean variable "flag" both in main and child thread. This "flag" is used to notify child thread to exit. I only use simple operation, e.g., "flag=false", "if (flag) {}". As I know, in java, "get and set a boolean variable" is atomic. So "synchronized" is not needed for variable "flag", declaring "flag" as "volatile" is enough.

Is this still true in Android?

How can i check if the returned location is reliable? I tried it with getAccurracy(), but this function even returns a accurracy although no gps fix is availavle (anymore). Is there a possibility to get gps dop values? Used SDK is 1.6.
