Why I can't implement OnKeyListener with parameter View such as on example where parameters are (View v, int keyCode, KeyEvent event) I'm forced to use parameters (DialogInterface dialog, int keyCode, KeyEvent event) but not the View as I want.

The green plane is shown on the golden-brown surface but when I press a key nothing happens. I want eventually be able to move the plane pressing 4 different keys + another one for shooting but that's easy if I can just get the thing moving in the first place. When I press a key in the emulator, nothing happens at all.

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 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?

I'm testing some functions with Android, JNI and NDK. I have the following JAVA class:
import android.app.Activity;

private int contador;
/** Called when the activity is first created. */...........................
Just like the html a tag, I want dispaly a link text, when user click the linkView then trigger some evnet( link: open a new page). when user click the google text ,then open the google home page: www.google.com. I saw the TextView and the Linkify class, but is can only display the url to a underline link text.
View 3 Replies View RelatedIn the Android docs on AlertDialog, it gives the following instruction and example for setting a custom view in an AlertDialog:If you want to display a more complex view, look up the FrameLayout called "body" and add your view to it:First off, it's pretty obvious that add() is a typo and is meant to be addView().I'm confused by the first line using R.id.body. It seems that it's the body element of the AlertDialog but I can't just enter that in my code b/c it gives a compile error. Where does R.id.body get defined or assigned or whatever?
View 2 Replies View RelatedI have a ListView that displays a set of notes, each with varying ammounts of data (i.e. some have a due date, others don't).Currently, each view in the list is a RelativeLayout containing a TextView for each field, plus two Button and a CheckBox. I then simply hide the unused fields by setting visible false on each one.This has worked well, but I'm about to add a lot more data fields to the notes and inflating that many unneeded views for each row will surely kill my app. I need a more dynamic solution.I've decided the best way to go is to create a custom view. How can I implement/design my view so that it can display a variable number of text fields without creating/ destroying textviews each time (which would be quite expensive and worse than my current situation), or maintaining a large pool of hidden textviews?
View 2 Replies View RelatedI have implemented a custom adapter the extends from the BaseAdapter and implements the getView method. It works fine except for one thing, not once do I get the convert View (a parameter to the getView method) that is not null (that can be reused).
View 2 Replies View RelatedI defined an EditText-field and I want to be informed when the user edits that fields.
So I thought: simple - I add an OnKeyListener and so I did. But even though the text field gets edited (and even displays the entered/modified text) I don't get any callback, i.e. the LOG-output doesn't show up.
CODE:......
why that callback is never called?
Android is really full of oddities! It seems that almost nothing I touched so far worked immediatly as one would expect. And - believe it or not - I have LOTS of experience with GUIs, esp. in Java (AWT, Swing, SWT, you name it...) But Android is a really tough beast!
I need to implement a list view with checkbox and each item should be associated with images.
View 1 Replies View RelatedI am using one class which extends ListActivity and One class extending BaseAdapter.
The Base Adapter uses getView function to inflate layout from xml.
The xml contains a text and a button to delete the row of list.
Please let me know how to handle the button click in the ListActivity class.
Sample code there is a method getitem(position) in the class of image adapter which returns null for the sample example. However, this method is important and is supposed to return the corresponding data item of the image adapter. For example the image adapter could generate a series of customized image views by magically calling the getview method. How could we implement the getitem(position) method under this case to help us gain access to these customized image views?

How to pass a parameter to an application that I call from my Application?
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'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?
