I was wondering if there is a way to show a widget that I have created inside an activity. I have a weather widget and I also have an app I am working on that I would like to include weather reports in. Is there a way I can just re-use the widget code and make it show inside the weather activity?

I have a widget layout xml which sets the src to the delivered android widget 4x1 frame image.Here is the widget layout code...
@drawable/widgetinitial holds the widgetinitial.png image example 4x1 at developer.android.com (AppWidget design guidelines).(4x1_Widget_Frame_Portrait.psd) What I am trying to do is display an image inside the delivered frame instead what happens is the frame image goes away and only the image I am trying to display shows up. How can I display the image inside the bounding box or the background?
Another question - I think I saw in a couple of forums AbsoluteLayout is a deprecated feature for Android 2.1 and above. Is that correct? and does using AbsoluteLayout throws any force close or other exceptions?
I am new to Android and this is my first question here so please go easy on me.

Currently 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.
I am building a android aplication which will be consuming a json file from the internet. This json file contains a list of news from a particular website. Each json object contains information such like title, summary, descripition and web links for the news thumbnail and the original image.
I will be displaying in a listview three information: the news thumbnail, the title and the summary. Here resides my problem. I dont want to load all thumbnails from the internet if they wont be displayed. What I am trying to say is that why download a thumbnail from the 30th news if the user wont scroll down the image. So, i will, initially only download the thumnails from those news that are being displayed in the screen and when the user scrolls down to see more news, as soon as the list item appers to the screen i want to download the image and then display.
Is there a way to achieve this? Is it possible to find out if the list item is on the screen? I have been searching all over the internet for a solution for this but i am running out of ideas.

This question was raised a few months ago here: http://groups.google.com/group/android-developers/browse_thread/threa... which suggests that animations cannot be done within an App Widget.
However, I'm sure I've seen some App Widgets animating... I have an App Widget which contains an ImageView. When the user clicks on this Widget I would like the ImageView to continuously rotate until a certain task (think synchronization) completes. This can take anywhere from a few seconds to a few minutes.

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'm able to successfully use a ScrollView inside the layout xml file for an application. However, when I tried using a ScrollView inside the layout xml file for a widget, I get a "Problem Loading Widget" error as soon as I drop the widget in the emulator. If I comment out the ScrollView, then the widget shows up in the emulator. I've pasted my layout xml file below. Any thoughts on how to get past this error would be much appreciated.

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.
View 5 Replies View RelatedI have a click listener:
private OnClickListener onMyListener = new OnClickListener() {

And my Method:

When it calls this method, at tv.getText() it breaks in the debugger.

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.
Here is my code.

I hav an app that is like a relational database. There is a main app activity that users manage things with. There is also a widget that will display important info and add data to the database. When the widget is clicked, a configure class displays a way for the user to edit data. When the configure activity is done, the widget is updated and instead of going back to the home screen, the apps main activity is started. I can't find where the main activity is being called from. Wouldn't I have to create an intent and start Activity() to get this behavior? When done updating, I want the home screen and not my app.

View 9 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?
