Android :: Cannot Call Method Of View Object Inside Activity
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); } }

Android :: Can Update A List View In One Activity While Im In Another Activity
I currently have a tab layout with 2 tabs, one tab with a list view and one with the option make strings so I can add them in the list view. Both tabs have their own activity because this made the code much more structured, and I dont have to repeat my self later. Lets say im in the tab that offer me to create an string, and i press the update list button, how do I update the list view without startActivity()? If i use startActivity(), it starts List.java, and instead of displaying the list in the list view tab, it takes full screen, which defies the purpose of the tab view. In other words, the startActivity() steals the focus from the tab view of the list, and sends it fulscreen. I want to update the activity in my list view tab, without starting a new activity that goes to fullscreen, and doesnt update the one in the tab.

Android : Way To Stop GPS Inside An Activity
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.

Android :: Put Camera Preview Inside A Surfaceview In An Activity Xml Gui
I just got my camera preview working for my app, but it is not appearing where I want it to appear, and I'm not sure how to get it there. 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: public class TakePic extends Activity { SurfaceView camSurface; Preview camPreview; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE);//hide window title camPreview = new Preview(this); //create preview setContentView(R.layout.takepic); setContentView(camPreview); //set preview as activity content camSurface = (SurfaceView) findViewById(R.id.camsurface); }

Android : Access A Method Of An Activity Inside TabActivity?
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?

Android : Inside TabActivity / How To Get Instance Of Current Tab 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.

Android :: Method Of Service Does Not Take Place Immediately From Inside 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.

Android :: Get Activity Object While In View Context
This is a followup to this post: http://stackoverflow.com/questions/3897176/findviewbyid-in-a-subclassed-surfaceview-throwing-runtimeexception Based on Romain Guy's feedback (which I'll accept shortly as it is a solution), I'd like to obtain the calling Activity from within the View, so that I can use it to obtain the desired Text View resource. I don't see any methods in View that return Activity. What is the proper way to do this? Or is there a better alternative for working with TextViews from within another View context. Basically, I am calling setContentView(R.layout.xxx) in onCreate() (as usual), so I don't really have a way to pass in references to additional TextViews unless I awkwardly retrieve the View after setContentView and then make calls on it.

Android :: How To Start An Activity From A View In Droid?
Is there a way to start an activity from a view? I have this nice view that renders these menu buttons and when they click a particular button (Trapped in an onTouch event) I want to start the "clicked" activity. It seems that there from my view startActivity method is uncallable. So that leads me to believe that there is no way to do this, in which case I guess I am asking, what do I do here when I want this menu to have a view that animates drawables and can get touches to know what "button" was pressed to know what activity to start?

Android :: Way To Add A View To Overlap Other Views In Layout / Activity?
Is it possible to add a view dynamically that overlaps other views in the layout. I have Linear Layout defined for the activity. As part of the Layout I have a custom View. The content changes dynamically and sizes appropriately based on the content size, with fill_parent for width and wrap_content for height. But what I want is, dynamically take over the full screen and then based on a click go back to the normal mode. Is there a mode to display a view where - in it can overlap all other views in the layout?

Android :: How To Determine View Size Right After Activity Has Been Started?
I want to do some data processing (in a thread) right after my main Activity starts. For that data processing to be started I also need to know a visible size of my main View (which is a LinearLayout currently, but whatever).I wonder how to do that. I.e. I wonder what is the entry point (callback?) I should use to be sure that my main View has been layed out, so i can use view.getWidth/getHeight? Is creating a custom View and reimplementing it's onSizeChanged() - the only way? In this case how should I properly describe it in my xml layout file? (it will contain some child views)

Android :: Detect If A View's Parent Activity Is Paused
In one of my Activities I have a ListView that displays a list of locations. For each list item I want a little arrow icon that points in the direction of the corresponding location. I implemented this icon by extending ImageView. This custom View has a listener that reacts to changes of the device's orientation by rotating the icon image accordingly. I register the listener in the onAttachedToWindow() method and unregister it in onDetachedFromWindow(). This kind of works but the problem is that onDetachedFromWindow() sometimes gets called only a long time after the containing Activity has paused. Also, the whole layout overall seems a little hacky. So my question is: Is there a proper way to unregister the listeners or would you implement this in a completely different way to begin with?

Android :: Invoke Changes To A Custom View Object From Its Activity?
I have a custom view that draws to a canvas. I am trying to invoke changes to the canvas when the user pushes a button from the activity that this view is tied to. Currently, I am attempting to do this by calling a public method, called setNewDrawable, that I created inside the view. The debugger is giving me different values for the view ID depending on whether I'm inside setNewDrawable or inside the Overridden onDraw method when I post an Invalidate. For example the debugger variables show: (This - MyView id=830067720176) or (This - MyView id=830067712344) in setNewDrawable and onDraw respectively. This makes me think I basically have two copies of the object and I am essentially interacting with the wrong one. How can I get information to my custom View in order to determine what it draws? Here is the code I am running...

Android : How To Ensure View Isn't In Focus When Activity Starts?
I open an Activity which has a number of elements... some TextViews, some Buttons, and an EditText. For some reason, when the activity starts, the EditText is focused by default, which causes the keypad to appear hiding the screen. I only want this EditText to be in focus if the user clicks into it. How can I ensure that this View isn't in focus when the activity starts? I've tried calling requestFocus() on one of the buttons, but it hasn't changed anything. Ideally, I don't want anything in focus at all.
