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?

View 1 Replies View RelatedI'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.

View 4 Replies View RelatedI want to build my own custom view which should look like the Crysis-GUI.At first I designed a XML-based Layout and made it visible via the setContentView(int resid)-Method. Worked pretty well.But now I wan't to go a step further and draw in my Layout. So I created a new Class, let it extend View and overrode the onDraw()-Method. So far so good.But how can I still use my XML-Layout? I can't do setContentView anymore, so how could the same effect be achieved?

View 1 Replies View RelatedI 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.
View 1 Replies View RelatedI am on Android 2.1 and I have one multi column Custom listview Using BaseAdapter with an editable edittext at the end of the listview. If the data in the listview do not contain the data of user choice then user should be able to enter data. If the data is already there in the list user will be able to select the data using custom selector. If a selection is made in the list view and user wanted to enter data in the text field at the bottom after selection then the marker in the list view should be unselected. I tried to use onclick() method on edit text using click listener. First time when it is clicked, edit text is getting focus and onclick() method is not fired. And when it is clicked second time, onclick() method is fired and notifyDataSetChanged() method is called. I tried to call the notifyDataSetChanged() method from the Focus Listener, list view selection is gone in my first attempt and edit text is not receiving any data input from the keyboard (frozen).

View 2 Replies View RelatedI'm creating my own View class, and defining custom xml attributes with a attrs.xml. As long as I provide each attribute manually, there is no problem, but
code:...................
The android:text is properly set in my instance, but the borderDrawable is not. I guess this has something to do with namespaces, because inside the styles.xml, the name="mypack:borderDrawable" is not handled by the XML parser's namespace facility, because its inside an attribute value. So "mypack" is in no way connected to "http://some.weird.url.com/seems/not/to/ matter" and adding it via xmlns:mypack... to the stylefile would not help, I guess. In the same file, "android:text" is somehow recognized, even though "android" is AFAIK only a ns-defintion for [url], which is also not declared in that file.
So what is the proper way to set a custom attribute in a style?
I'm writing my own custom view, a keyboard, which I think the ArrayList in the keyboard view is causing the application to quit in the emulator.
public static ArrayList<HexButton> hexButtons = new ArrayList<HexButton>();
The application ran fine when I did
setContentView(myKeyboardView);
But I want to nest my keyboard with a TextView so I'd like to be able to do
setContentView(R.layout.main);

Currently, I am creating a custom View class (DrawView) that inherits the View class and adding to my activity programatically by using RelativeLayout and LaoutParams etc. But is there an easier way to do this by adding my DrawView to the layout XML file?
View 4 Replies View RelatedI was attempting to add a custom view in XML, but I kept getting force closes. It works fine when I just find the parent and use addView() so it isn't the code. I'm pretty sure I'm just getting the constructors wrong. Does anyone have any experience with this?
Here's what I've got:
CODE:................
I'm trying to create a button in a custom view that I've created. I'm looping through an XML document and drawing certain things. I want to be able to also create buttons to go in certain locations depending on the xml data. I'd like to do it in the view because I want to be able to call invalidate() on my view to redraw things and replace the buttons when new xml data is available.
The problem is that I put my code in the view class, the activity crashes because the button is "null".
Here is a subset of my code:
CODE:............
I know this code works for creating buttons because I can put it in my activity class and it works just fine. Any suggestions? I thought about relocating the button in the activity, but I can't figure out how to do this when new data is available.
I'm writing a little custom view which can be in two states : checked, not checked. According to the state it is in, it's background changes. Quite straightforward sort of behavior. My class extends FrameLayout and implements the Checkable interface.
In my toogle method I just calls the setChecked method with a boolean corresponding to the new state. My setChecked method simply sets a mChecked boolean and calls the refreshDrawableState method. Pressing the view should then toggle it back and forth between the states check, unchecked.
The background of the FrameLayout is given a StateListDrawable in which I've defined a drawable item for the following states: state_pressed, state_focused, state_checked=true, state_checked=false.
When I press my custom view, the background changes all right back and forth between the state_pressed=true and state_checked=false items. But state_checked=true is never called.
I've created a custom view via .xml file, and I wanted to add it as a a contentView to an alert Dialog usinf a dialogBuilder:
CODE:.................
The problem is...I can't get my view from my custom layout... I only have an id (int)...
I tried Resource.getLayout(int) => it returns an xmlParser... not very usefull ...
finally the solution I comes up is so disgusting ( it worked but ... let's have a look)

How can I do that easily without using such a disgusting way... ?

View 2 Replies View RelatedI have a custom class that extends view class. Now this custom view is set in the listadapter that extends baseadapter. Along with the custom view I have a TextView in the list.
So the xml i inflate for list view is
CODE:......
the customview sets a rounded rectangle behind the text in TextView. Now The height of the textview vary as per its content. So I want the height of the customview also vary as per the height of TextView.
I am trying to do is to embed a custom view in the default layout main.xml:
CODE:......
As you can see the class is called com.lam.customview.CustomDisplayView, with the id of custom_display_view1. now in the com.lam.customview.CustomDisplayView class, i want to use another layout called custom_display_view.xml because i don't want to programmatically create controls/widgets.
Custom_display_view.xml is just a button and an image, the content of which i want to change based on certain conditions:
CODE:..............
I tried to do:
1)
CODE:........
But got this error, "03-08 20:33:15.711: ERROR/onCreate(10879): Binary XML file line #8: Error inflating class java.lang.reflect.Constructor ".

But got this error, "03-08 20:28:47.401: ERROR/CustomDisplayView(10806): Resource ID #0x7f050002 type #0x12 is not valid "
Also, if i do it this way, as someone has suggested, it's not clear to me how the custom_display_view.xml is associated with the custom view class.
I've created my own view by creating a subclass of the SurfaceView class.
However I can't figure out how to add it from the xml layout file.
My current main.xml looks like this:
CODE:............
What have I missed?
My view looks like this
CODE:..............
And it works fine like this:
CODE:..................
But nothing happens when trying to use it from the xml.
I have a ViewFlipper defined that contains 3 views...
CODE:.........
I also have a custom View defined within my Activity...
CODE:........
Some how, I need these linked together so that the 'third_view' defined in the XML layout file needs to be a CompassView, or have a CompassView added to it.
What I can do is drop the 'third_view' from the layout and then add in the CompassView manually..
CODE:........
But then I lose the ability to define other view controls within the layout file.
Can I add CompassView to 'third_view' declaratively?
I have an XML file in my layout folder that has how i want my custom widget/view (not sure what correct terminology is here).but how do i make it so that i can programatically, add one or more to an activity

I am working on adding vertical and horizontal scrollbars in a custom drawn View. I have overridden the compute*ScrollOffset, compute*ScrollRange, etc methods and have enabled the scrollbars by called set*ScrollBarEnabled. However, I do not see the scrollbars in my View, even after a call to scrollBy, which according to the documentation calls awakenScrollbars (I assumed awakenScrollbars is not required as the scrollbars do not auto-fade - isScrollbarFadingEnabled returns false).
