General :: How To Install Widget From Activity View
Feb 11, 2012
is there a way to install a widget from a Activity view? I've implemented a Activity which shows the user all widgets installed on the system, the user can tap a widget icon to "install" the widget on the workspace.
If the app is installed as "user app", i cant bind the widget to the allocated id, if i install the app as "system app" in /system/app, all is working.
can i workaround that or is it in android gingerbread only possible to pick a widget through the system wide "pick/choose" activity/dialog?

I have a selection for some items using a spinner widget. At the moment the spinner will load a simple Textview and show the name of the item.It is possible to define an own view to show inside the spinner row? I would suspect it being similar to a custom List row.I simply want to show an individual icon left from the spinner text for each item in the list.

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.

I am working on developing an app and I am not sure when should I use a new activity and when should I update the existing view.
For example, lets say I have a view that shows a multiple choice question.Now, when the user selects his choices and clicks on say "Evaluate", I want to show the same question view but along with the right answers and explanations for each option. So does that mean, I should send an Intent upon a click on Evaluate or I should just update the view (i am not sure how)?
If I send an intent and show a new screen, how can the user go back to the next question without displaying the answers? If I don't create an new activity, how can I update the existing view that is already displayed?

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.

I have ListViewActivity
public class SelectActivity extends ListActivity {
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.select_one_of);
SimpleAdapter adapter = new SimpleAdapter(
this,
createChildList(),
R.layout.select_one_of_childrow,
new String[] { KEY_VALUE },
new int[] { R.id.selectoneof_add_new_item});
setListAdapter(adapter);
}
// ...
}
after setListAdapter() calls I would like to execute the following code:
((TextView) getListView().getChildAt(0).findViewById(R.id.selectoneof_add_new_item)).setCompoundDrawablesWithIntrinsicBounds(0, 0, R.drawable.ticked, 0); but getListView().getChildAt(xxx) returns null and I catch NullPointerException. Where should I put mentioned above code-snippet?

Can I use a custom view like com.examples.me.customview in the xml file of a app widget and can then draw in the onDraw of the custom view? Or do I have to draw into the drawing cache of an ImageView instead?

In one of my androids activities, I have several widget in a vertical linearlayout. The length of this layout is bigger than the screen and thus I cannot see the widget at the bottom.
In the Emulator, is there a special scroller to implement or a particular action to do to be able to scroll up and down?

I have a custom view that needs a reference to the activity that created it.Dianne Hackborn said in another thread: >Give your view a reference to the activity (or a Java interface it implements) and call back through that. >Much much MUCH more efficient than sending a broadcast. >See all of the standard view and view subclass callbacks for examples.

I'm writing an app that will host widgets. The app has custom view (which probably is the source of issue).mView.addWidget() basically just remembers this AppWidgetHostView instance and then mView draws it directly onto canvas. Visually everything is fine.I can see the actual widget. But the issue is with reacting on UI events. Please advise what needs to be done in the parent view in order to correctly trigger handlers in the widgets like onClick().I used standard widgets which normally react on click events. None worked.I also created my own test widget with listener and onClick()is successfully triggered if the widget is added on Homescreen, but doesn't work in my app.mView correctly detects click event and I tried to call widget.perform Click there, which returns false meaning onClickListener is not registered in the widget. But according to source .would call updateAppWidget which would register its onClick listener.

instead of referring the custom widget by a fully qualified class name, is it possible to map with a shorter name. Like it happens in ant custom tasks (though properties file).

How do I add a View dynamically in an android widget? I realize that the RemoteViews works as a container of updates, but the RemoteViews.addView is only available on API level 7 (and I want my widget to work on HTC Hero phones, which has API level 3).

I just started developing a simple Android application while I'm still learning its platform. I'm using Eclipse IDE with the ADT plugin 0.9.6 and I need to know if it's possible to view the activity stack that is associated with a Task. Is there any way through the DDMS tool or through any other technique?

Everywhere I look online, it seems that I must use an animation to change views dynamically (like slide in, out). Do I have to do this, or can I simple just setContentView() on each new activity?

I am trying to make an Accordian control where each section would have its own view accompanied with its own activity. With the TabHost I can add tabs based on Intents and it is this behavior I am trying to understand how to use. So given an intent or an activity how can i get the view?

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.

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?

So I have my main activity. It starts out adding a custom SurfaceView called DrawView as the content view with
DrawView drawview = new DrawView(parameters);
this.setContentView(drawview);
now my layout.main.xml is a layout with a video view which I am using to play my cutscenes. I am able to switch to this view by calling a method I made which switches the content view by
this.setContentView(R.layout.main);
which works fine when I am calling this method within the Activity. Only problem is I need to call this method from within DrawView! The method I made to switch to my cutscene is public and I do pass the Activity (named Draw) as a parameter of DrawView.
So when I do call this method from within DrawView my game freezes and will subsequently crash! however it works when method is called locally?
