How To Create Custom Method And Call It
Jun 3, 2012
So how can I create a custom method.I have several image buttons that I need to change the characteristics of such as an image when it is pushed and when it is not pushed. So when I push one button it changes to a pushed image for that button and ALL other buttons revert to an unpushed image. Currently I have to have this code in every button click method I would LOVE to create one method that I can call from each button click method that way if I have to change anything it is in one place.
I would love to when a button is tapped
call the custom method to revert all buttons to unpushed
then change the button being tapped to pushed
A very common process but I can't figure out how to write the custom method and then call it,,calling it should be simple something like custommethod.

I am using the following method in a new application I'm developing. There is a main activity, which instantiates different classes that extends RelativeLayout and I'm using setContentView to switch between the different modules of the application. I wonder if this is a good approach or necessarily I have to use different activities to the several screens the app haves.

Basically I'm calling the onDraw method like so...
code:...................
You see I'm drawing it on top of a Camera view and the information being drawn is subject to change. I have a listener setup which will update the variables being drawn at the appropriate time but I now want to "refresh" this draw in that listener.

I want to call a method every X minutes, if my method got a result it ´should inform the user by vibrating or showing a alertbox. if the method doesn't get a result it should wait for X minutes and restart. What is important, this should also work when the phone turns to sleep. Which means I want to wake the phone from sleep to run my method. Actualy I can activate my method via a Button, and it is working like I want it to be except the background loop thing.
I already searching for a solution here in the group or also on google but I think I don't got the right search terms to find a solution for my problme. I already read about the AlarmManager and broadcast receiver but I'm not sure if this is right for my problem.

is it possible to start a context menu on the onCreate method? I know its probably bad design ethics but I have my resons! I've tried the: register For Context Menu (this.getCurrentFocus()); But its not working.. So does anyone have any better ideas?
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
LinearLayout layout = new LinearLayout(this);
layout.setLayoutParams(new
LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
//Button button = new Button(this);
//button.setLayoutParams(new
//LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
//button.setText("my button");
TextView text = new TextView(this);
text.setLayoutParams(new
LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
layout.addView(text);
setContentView(layout);
registerForContextMenu(text);
openContextMenu(layout);

I 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?

my app is working perfectly and playing its music in the 1.5 and 1.6 emulators, my ADP1, and for everyone in the Android Market (at least there were no complaints). The problem is that when the app is run on the ARCHOS 5 tabled, the MediaPlayer.create(Context context, int resid) method returns null. I guess there might be a problem with the ARCHOS' Android implementation, but did anyone experience the same problem? What might be a possible reason for the create method to return false? The docs don't say anything. I'm also using SoundPool in parallel with MediaPlayer if that's relevant.

I'm writing a custom ContentProvider that serves up content consisting of a single, constant string which I represent as a one-row table having columns _id = 0 and value = "SomeString". This string is not stored in a database, so I developed a subclass of CrossProcessCursor that has does everything required to behave like what I described above.
The documentation for CrossProcessCursor is very sparse and doesn't really explain what the fillWindow() method should be doing beyond the obvious. Based on the descriptions of CursorWindow's methods, I put the following together, which I thought should cover it:
CODE:...............
As expected, it gets called with pos = 0 when a client application requests the content, but the client application throws an exception when it tries to go after the first (and only) row:
CODE:..................
what this method should be doing to return a correct-looking row to the client?

I have placed an icon on the status bar. I would like to run a method of another class whenever the user selects that icon. I've seen similar functionality used in volume icons that sit on the status bar that allow a user to raise or lower the volume when the icon is clicked. However, these icons are on the right side of the status bar, and from what I've seen, I'm not allowed to put an icon there. I don't know if that kind of functionality is available to left side icons. So basically, I'm looking for how to run a function when a status bar icon is clicked. I don't want to open an activity, I just want to run a function.

You need a reference to the class that contains the method you want to call. To access the method homepage() inside the eSkyGuide from the class Weather, you need an instance of the eSkyGuide class inside the instance of the Weather class.

I want to implement a custom input method for certain EditTexts within my app. I understand I need to extend the InputMethodService class, but how do I then add this to certain views? I've tried just using the class name in the android:inputMethod XML property, but this seems not to work. Using the SoftKeyboard example in the 1.5 SDK, my manifest is as follows:..............

How can i call the onUpgrade Method of the database? Background of my question: I do a backup on the sdcard of the full database. And the user can restore this database. But if in the meantime (between backup and restore) an app update has made changes to the database i get a problem on restoring. The new columns are not there after restoring. So i want to call the onUpgrade method to add all new/changed columns. Or is there a better way for this?

For Android, I have a custom view which I fill up with primitive shapes in the onDraw() method. Coming from a Processing background, I expected the draw method to be called automatically 30 times per second, but its clear that that's not how android views work. So how should I go about calling this method 30 times per second?

I was wondering in what order the following methods - on Draw(), on Measure(), on Size Changed() - are called automatically when we create a custom component. Not sure if this question makes sense. I've just been kinda confused as to what the methods are supposed to do exactly.

The following code leads to "java.lang.IllegalThreadStateException: Thread already started." the second time it is run through on the program This happens the second time updateUI.start() is called. I've stepped through it multiple times and the thread is called and completely runs to completion before hitting updateUI.start(). Calling updateUI.run() avoids the error but causes the thread to run in the UI thread (the calling thread, as mentioned in other posts on SO), which is not what I want. Can a Thread be started only once? If so than what do I do if I want to run the thread again? This particular thread is doing some calculation in the background, if I don't do it in the thread than it's done in the UI thread and the user has an unreasonably long wait.
