I draw a space ship :
Code:
private void spawnSpaceship() {
Rectangle spaceship = new Rectangle();
spaceship.x = MathUtils.random(0, screenWidth-32);
spaceship.y = screenHeight;
spaceship.width = 32;
spaceship.height = 32;
// spaceship.energy = 100; <= this line won't compile
spaceships.add(spaceship);
lastDropTime = TimeUtils.nanoTime();
}
As you can see, spaceship has parameters : x position, y position, width, and height.
I'm a noob and I would like to add an "energy" parameter but this line won't compile :
Code:
spaceship.energy = 100; <= ERROR
while I'm testing my app with Monkey test tool, I ran into the following exception: "IllegalArgumentException: parameter must be a descendant of this view"
I don't really understand why this exception happens, so I did some research about this and found the following: http://groups.google.com/group/android-developers/browse_thread/threa...
According to the above post, the issue once was resolved in Donut release, but some ppl say it still happens. Is there anyone who knows anything about this issue? As far as I understood, this issue shouldn't occur unless you intendedly call the method ViewGroup.offsetDescendantRectToMyCoords to get an exception.
My app is using Tab, which means it has a lot of views in it. (including view changes too.) I don't really call setContentView repeatedly in my app though. Someone in the above post said that calling setContentView several times can cause this issue, so I just wanted to make sure that my app is not the case.
I'm using eclipse to develop over android, i'm trying to connect to a .net webservice...when i'm calling a webmethod with no parameters it works fine... but when i come to pass a parameter to the webmethod things turn upside down... the parameter is passed as null (while debugging the webservice i discovered that) and i get a null from the webmethod in the client side code... i've been searching for a solution for a day now and all that i can interpreter is that people keep talking about encoding styles and such stuff.... i've tried it all but in vain. i'm using ksoap2 version 2.3 with the following code:

View 1 Replies View RelatedI wanna start a Service and need some Objects in my Service to work with them.
I would like to have an custom constructor like this:
Code:
public MyService(Context context, Button button, Cursor cursor)
But the common way to start a Service is like that:
Code:
intent.setClass(this, MyService.class);
startService(intent);
In an Intent I can only put Data like Strings.
How I can start a Service with some Objects as parameters?

View 1 Replies View RelatedI noticed a lot of Android functions have a parameter that you can pass in that's a bitmask, for different options, like on PendingIntent, you can pass in things like you can call getActivity() with PendingIntent.FLAG_CANCEL_CURRENT|PendingIntent.FLAG_NO_CREATE.
I'm wondering how I can create a function that has a parameter like this?
I did was use the search function and after 10 pages I could not see what I was looking for. In java, we use method parameters for a number of reasons but I've never used parameters in my methods unless I needed them..When defining a method in android for a button that I want to click, I had my method defined in XML under the Button element
[HIGH]androidnClick="showText"[/HIGH]
then, in my ProjectName.java file I defined the method
[HIGH]public void showText(View view){
}[/HIGH]
I was told that the View in the parameter is the view that was clicked.Button is a subclass of View as is TextView and since that is the case,is this the rule for just the onClick method? Also, why can I not pass the Button as a parameter? Button is the actual "View" being clicked, so why not Button?
Furthermore, are there other methods similar to this and if so, do they all follow the rule just like the View parameter, where let's say if I had a class called "A" and it had a subclass "B" and that class had a subclass "C", and if I wanted to use the onClick method, I can only pass the Highest Class as the parameter?
To simplify that, are there ever cases where I would pass anything else OTHER THAN "View" as the parameter to these methods?
I'm building an android application, which has a list view, and in the list view, a click listener, containing an onItemClick method. So I have something like this:
public class myList extends ListActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
getListView().setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
/* Do something*/
}
}
}
Normally, this works fine. However, many times I find myself needing too preform an application using the outer class as a context. thusfar, I've used: parent.getContext(); to do this, but I would like to know, is that a bad idea? I can't really call: because it's not really a subclass, just an embedded one. So is there any better way, or is that considered cosure? Also, if it is the right way, what should I do if the embedded method doesn't have a parameter to get the outside class?

The preference type of UI is used in many Google built-in applications for example Bluetooth , Wifi etc. And the getView of the preference is used to set the image or text to make it visible in the UI screen.
the getView for the pref type UI is defined as below in framework code : ->
CODE:..............................
Where the convertView is not getting recycled and every time whenever the user is scrolling the list up and down, convertVIew comes out to be null.Therefore by logic inflation of the UI also happens all the time in onCreateView().This is a kind of shortcoming in terms of memory utilization , hence in a discussion (MAKE YOUR UI FAST AND EFFICIENT) where Romain Guy has mentioned about the tricks to increase the app performance doesn't hold good for preference type of UI.
I have made customAdapter (which extends BaseAdapter). I want to reuse the old views..

I'm new in Android development and I have the next question/problem. I'm playing around with the Media Recorder class to record just audio from the microphone. I'm following the steps indicated in the official site:
http://developer.android.com/reference/android/media/MediaRecorder.html
So I have a method that initializes and configure the MediaRecorder object in order to start recording. Here you have the code:
this.mr = new MediaRecorder();
this.mr.setAudioSource(MediaRecorder.AudioSource.MIC);
this.mr.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
this.mr.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
this.mr.setOutputFile(this.path + this.fileName);
try { this.mr.prepare();
} catch (IllegalStateException e) { Log.d("Syso", e.toString());
e.printStackTrace();
} catch (IOException e) { Log.d("Syso", e.toString());
e.printStackTrace();
}
When I execute this code in the simulator, thanks to logcat, I can see that the method setAudioSource(MediaRecorder.AudioSource.MIC) gives the next error (with the tag audio_ipunt) when it is called:
ERROR/audio_input(34): unsupported parameter: x-pvmf/media-input-node/cap-config-interface;valtype=key_specific_value
ERROR/audio_input(34): VerifyAndSetParameter failed
And then when the method prepare() is called, I get the another error again:
ERROR/PVOMXEncNode(34): PVMFOMXEncNode-Audio_AMRNB::DoPrepare(): Got Component OMX.PV.amrencnb handle
If I start to record by calling the method start(). I get lots of messages saying:
AudioFlinger(34):RecordThread: buffer overflow
Then after stop and release, I can see that a file has been created, but it doesn't seem that it been well recorded. Anyway, if I try this in a real device I can record with no problems, but I CAN'T play what I just recorded. I guess that the key is in these errors that I've mentioned before.
I am using Android SDK 1.5. I am developing an activity with multiple content views. It will call setContentView() with different viewgroup instance for different functionality. It contains a text input dialog popped up by an option menu item. I didn't specify anything for IME in mainfest.xml & EditText attributes. I found at first, the soft keyboard for the text input dialog will overlap on the activity content view. But after several content view switch (by calling setContentView() with different ViewGroup instance), the soft keyboard will resize the activity content view. Why this inconsistent behavior happens?
