I want to embed the analog clock in my application.
I use <AnalogClock android:layout_width="wrap_content" :layout_height="wrap_content" /> in my layout XML file, but the clock's appearance is different from the one added in Home screen. I know I can copy the AlarmClock's images to my project. And in xml file, set the android:dial, android:hand_hour,and android:hand_minute to my project's images. But I want to know is there a way to directly reference the resource in the AnalogClock?

I am having a little trouble using some external source files. I am new to eclipse and the methods used to import external source files. Basically this is what I have done. Downloaded the source files for a java project called "TrueLicense" via CVS. Imported this library by going to "Projects" and adding the "TrueLicense" project (I am not sure if I should do this in "Source", "projects" or "Libraries"?) Imported the required classes into my android project without any compile errors.
When I run the program I get:
12-05 15:52:28.632: WARN/dalvikvm(724): VFY: unable to find class referenced in signature (Ljavax/swing/filechooser/FileFilter;)
Then a whole lot of other errors. This seems sensible as there is a sections of the TrueLicense package that used Swing. How do I only import the parts of TrueLicense that I need?
My app is comprised of a set of reusable Activities that other apps can reuse. For various reasons, I would like my Activities to be launched in context of the invoking Activity's process, instead of always being launched in my Activity's process (default behavior on Android). How can I achieve this?

View 3 Replies View RelatedCurrently working on a simple app to allow users to find various things around them. When the activity that shows the Google map is active I can see the GPS icon on the status bar, which is normal. But I need to be able to stop the GPS hardware when my user navigates away from the activity, and switch the GPS back on when the activity is shown.
Is there a simple way to stop GPS when a user navigate away from an activity? I have tried the LocationManager's removeUpdates() but this doesn't actually stop the GPS (the icon is still flashing on the status bar and draining the battery).
What I'm looking for is a simple way to programatically stop the GPS hardware.

Instead of using the entire screen for the preview, I would like to put it inside a surfaceview in an activity xml gui. What do I need to change? Here is my code:

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);//hide window title

I would like to access the public method of an Activity run by a TabActivity using: Code...
Basically, what I what is to let the parent Activity call a method in child Activity in order to do something. Is this possible?
I did try this:((TeamHuddleScreenMsgsView)getTabHost().getCurrentTabView().getContext()).refreshModel(); but I'm encountering a ClassCastException. It seems that the getContext() still gives the TabActivity. Any help on how to get the child Activity?
I have attached a menu to my TabActivity, and when a menu item is selected, I would like to do something different based on which view is being currently displayed in the TabHost.
int getCurrentTab() returns me the id of the current tab... but from that int how can I get the instance of the activity running?
I also tried getCurrentView(), getCurrentTabView(), but these return things I can't seem to cast to the class of the current activity.
I have an activity A which uses SharedPreferences to share data with a service S, which is called from within A.Now when I call the stopService() method from A, the onDestroy() method in S is not called immediately.I thought that all the activities and services under a single apk run in just one process. Why then does the jump to onDestroy() not take place immediately instead I can see the output from onDestroy() after the further code in the activity A is executed.

In my program I have a custom view object. Inside the view class is a method called foo. For some reason when I call foo from my activity, it doesn't fire. Here is the code:
XML of the custom view:
<com.company.application.MyView android:id="@+id/my_view" android:layout_width="wrap_content" android:layout_height="wrap_content" />
The activity code:
public class Main extends Activity { MyView mView;
/** Called when the activity is first created. */
@Override public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState); setContentView(R.layout.main);
LayoutInflater li = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View v = li.inflate(R.layout.main, null); mView= (MyView) v.findViewById(R.id.my_view);
//A button to fire the method inside foo() Button switchLeft = (Button) findViewById(R.id.switch_left); switchLeft.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { callTest(); } } );
} public void callTest() { Log.w(this.getClass().getName(), "clicked left arrow");
mView.foo(); mView.postInvalidate();
} }
Finally here is foo:
public void foo() { mBackground = mContext.getResources().getDrawable(R.drawable.temp_canvas); Log.w(this.getClass().getName(), "background set");
}
The first log is always written when the button is pressed, but the second log is not because foo never fires. What is the deal here? Upon request, the full view
public class MyView extends View { Drawable mBackground; Context mContext;
public MyView (Context context) { super(context); mContext = context;
mBackground = mContext.getResources().getDrawable(R.drawable.leftarrow1);
} public MyView (Context context, AttributeSet attrs) {
super(context, attrs); mContext = context;
mBackground = mContext.getResources().getDrawable(R.drawable.leftarrow1);
} public void foo() { mBackground = mContext.getResources().getDrawable(R.drawable.temp_canvas);
Log.w(this.getClass().getName(), "background set"); }
@Override public void onDraw(Canvas canvas) { Paint paint = new Paint();
paint.setStyle(Paint.Style.FILL); // draw a solid blue circle
paint.setColor(Color.BLUE); canvas.drawCircle(20, 20, 15, paint);
// draw a test background mBackground.setBounds(0, 0, 300, 400);
mBackground.draw(canvas); }
}
Basically what I am trying to accomplish is I want a canvas I can pass bitmaps to, to be displayed on the screen with the rest of my view objects (buttons, textviews, etc).
View 1 Replies View RelatedI am having issue while showing a WebView in an activity in the middle of the screen. I have an activity and I want to show a webview in the center of screen. My activity is transparent so background activity will be visible. Whenever I try to create a webview and add it to activity using setContentView(webview) it always shows the view on the top left corner of the screen. Is their a way to workaround this?I am trying to do this via pure code only.

I have written a widget that cycles through a series of movie poster images with next/prev buttons.This works.There is another button on the widget that needs to launch an external activity, sending it the name of the shown movie.The other activity is not in the same namespace, package or eclipse project as the widget.It is written by another developer and its apk is installed on my emulator.
View 7 Replies View RelatedI am using Sygic Navigation on my HTC Hero. I can start it by calling the correct intent as I described here. Now, Sygic starts in fullscreen-mode and I cannot use the BACK-button to go back to my previous Activity (dont ask me why).
The question is: is there some trick or way so I can control how that Sygic Activity is started? I want to add my own "header" on top; the header contains my buttons for navigation. It would be great if I could add that header, then have Sygic below that (as the "content" then, as shown here).
I am new to Android and this is my first question here so please go easy on me.
Is it possible to check some condition inside onCreate() of an Activity and display an AlertDialog?
I am creating an AlertDialog anonymously in Oncreate() and calling show on that instance but the AlertDialog is never displayed.
I would like my Activity to be informed when the SD card is removed, since it relies on files from the SD card (to keep apk size down) but for compatibility reasons is not targeted at Froyo. I'd like to close the application when the SD card is removed/mounted (giving the user a dialog message to inform them of course) so that I don't get IOExceptions etc (I'd quite like to not have to check everytime I load a file to see if the external storage is available, I already do a check on application launch). There doesn't seem to be any attribute in the manifest for this (like configChanges) that I can find.

View 8 Replies View RelatedI've been a couple of days trying to solve this thing but I can'f figure it out.The problem is, simple activity, with simple layout, ScrollView -> LinearLayout -> and a lot of buttons inside the layout (within the scroll content). Everything works just fine but one tricky thing. When I click a button let's say at the top of the scroll content and inmediatelly I scroll down to the bottom of the content and I click other button there, nothing happens until I click a second time and all come to normal again.This can be reproduced anytime and it's code independent (i've tried more than 20 scenarios). I've not much experience in android yet but looks like the scroll listener stops the onclick listener or something like that.
View 1 Replies View RelatedSo I've been extremely frustrated by this for a long time now.I've posted before, but can't seem to find a good solution. My goal is to have something pretty much exactly like the installed application details page in the Android Market.I need a list of items displayed along with other content above the list, and would like the content above to scroll up along with the list (exactly like the application details does for the "My Review" and other descriptive info).Due to responses to my previous posts, I came to believe that it really wasn't possible to do this with a ListView.So rather than using a ListView, I refactored my code to use a simple LinearLayout and add individual View items to the list, thinking I could just set each View as clickable and add an OnClickListener to each View in the LinearLayout.That's not working at all though, and now I'm getting even more frustrated.If someone can help me get the OnClickListener working, then I think it'll work, but I do need a separator for the LinearLayout.How do I add a separator like the one used for ListView to my LinearLayout?
