View 2 Replies View RelatedAndroid :: Create A Bitmask Parameter For A Function / Method?
Apr 30, 2010I 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?
Unused Parameter In OnClick Method
Nov 18, 2013I 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?
Android :: Passing Object To Method In Java Appears To Be By Reference
Sep 29, 2010I thought when you passed objects to methods in Java, they were supposed to be by value.
public class MyClass{
int mRows;
int mCols;
Tile mTiles[][]; //Custom class
//Constructor
public MyClass(Tile[][] tiles, int rows, int cols) {..........
At this point, any changes to the mTiles object are reflected back to the tiles object.

Android :: Show Method Definition - Eclipse Recognizes Warning On Method
Nov 22, 2010In Eclipse, when I mouse hover over a built-in method, it displays a method definition including stuff like what the method does, input objects, return objects etc. If I have a yellow line (warning) under the method I'm trying to use, I can't get the mouse-over to show the definition.

View 3 Replies View RelatedAndroid :: IllegalArgumentException - Parameter Must Be A Descendant Of This View
Jul 20, 2010while 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.

View 1 Replies View RelatedAndroid :: Pass In Object Java Class Embedded In As Parameter
Apr 19, 2010I'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?

Android :: Location DistanceTo Uses Error Parameter In Approximate Distance Calculation?

Android :: GetView Always Giving Null ConvertView Parameter In Preference Class UI
Jul 2, 2010The 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.
