Android : How To Create An ImageView In Java Code Within An Existing Layout
Jun 8, 2010
I'm looking for an easy way for the user to see how many drinks they've had for a BAC calculator.
PICTURE OF THE APP, for reference
On button press, I would like an image to be added to the screen, directly under the spinner and with left alignment. When I press the button again, I want another image to be added to the screen.
So if I pressed the add beer button, a drawable of a beer would appear below the spinner. If I pressed the add beer button again, I want there to be TWO drawables of beers under the spinner, preferably with them being added from the right.
(Also, having them reach their width limit, wrapping around, and starting again on the left, but below a full line, would be AWESOME)
I can't figure out how to do this. I assume adding a ImageView in code to a relative layout (because it needs to be positioned to the right) would be the best route, but if it's possible in xml I'd be more than happy to use that.

I have a layout in which I am displaying a webview. I want to add images on top of the webview at specific places through code.
Can some one please tell me how to do that?
The translucent background example in API Demos makes the view cover the whole screen. I want to place only a small image and at a specific location (origin not 0,0).

I'm trying to create a simple text based game in which I ask a question based on a movie. The list of movie's is in a text file which I've included in res/raw. So basically I want to have a default string, say "Who acted in", followed by the name of the movie. Could I have the first string (along with a submit button etc) in my res/layout/main.xml file, and follow that with the movies name, after I've extracted it from the text file in my activity, or does the layout have to be defined in one place only?

I have a custom view that I had to write for a large scrollable image, as the images are larger than the size of the screen. Before, I had tried to do it by putting the image into a ScrollView but that of course didn't work. The view itself is within a RelativeLayout within the activity and at the bottom of the screen I have two buttons that are used for navigation and at the top a TextView with a caption for the activity (the main header is already being used here for instruction). In my below code, I've checked the Hierachy Viewer to confirm all the elements are loaded and in the Activity I can see the TextView, however it overlays the ZN5ScrollView area and below the image I just have a blank area of the size defined rather than my buttons. For the bottom navigation, the Hierachy Viewer is saying the absolute_y of the bottom navigation is 480. I'm wondering if anyone can help with my layout code here to get this working correctly? Bottom navigation is 50px high, ZN5ScrollView is 365px above the navigation, and the TextView takes up the rest of the area at the top

I have a layout xml file with a linear layout. One of the children is again a ViewGroup Relative layout. In my java code i want to change the width of this child Viewgroup for my requirements. I tried this
ViewGroup childViewGroup = (LinearLayout)findViewById(childViewGroup);
LayoutParams l = childViewGroup.getLayoutParams();
l.width = 360;
childViewGroup .setLayoutParams(l);
I couldn't do this because findViewById(childViewGroup) doesn't fetch ViewGroups it does only for Views. Note: I cant define a whole new layout.xml for this minor requirement since it is huge layout file and might cause performance overhead. I wanted to just change the width of the child view group in my java activity code.

I know it is possible to develop a full flex application using AIR for android but what I need is to embed a flex component into an already existing classic Java android application.
I found some flash players in java but they all either require a JFrame or include of specific windows dlls.
Is it even possible ? I found no info on the net about this

I am going to create an application via improving an existing code which has Apache License 2.0. In the license, it is implied that I need to attach "Notice" and "License" files for the previous code while distributing my new application.
Where is the best place to put these files, before publishing the new version on Android Market?

Is there any class generators to process web services in Android/Java? I may have to write my own to generate classes against WSDL but I'm trying not to. Also is there one for REST services as well?
If not providing me with discovery service suggestions like disco/wsdl are good enough.

I have a layout with an image on it (embedded in an ImageView). I need to rotate the image (let's say) 90 degrees CCW. I've written code to animate the image rotating. The image smoothly rotates 90 degrees, but then snaps back to its original state. This is what the Android documentation says will happen after an animation completes. Presumably, on the notification that the animation has ended, I'm supposed to transform the ImageView (or the underlying drawable), and possibly invalidate it to trigger a redraw. All well and good, except that I can't find a way to do it, and I can't find any examples of anyone else doing it. I tried using getImageMatix/setImageMatrix on mImageView, with no apparent effect. There are subclasses of Drawable that will rotate an image, but there is no setDrawable() method on ImageView, so I don't see how to use one.

I want to add an unknown number of ImageView views to my layout with margin. In xml, I can use layout_margin like this:
<ImageView android:layout_margin="5dip" android:src="@drawable/image" />
There is ImageView.setPadding(), but no ImageView.setMargin(). I think it's along the lines of ImageView.setLayoutParams(LayoutParams), but not sure what to feed into that.
Does anyone know?

I was looking over this code about extending an ImageView: http://marakana.com/forums/android/examples/98.html
And i was wondering how can i add the new View to an existing xml layout file, along with some other views.
Already i did this inside my main linear layout:
CODE:..........
But the problem is that this way the onDraw method doesn't get called.
Maybe some examples where you combine CustomViews with xml layout.

I have an ImageView that is defined in the following way.. Now after downloading a new bitmap I change the drawable. The image now appears in the top left corner of the ImageView. Is there a way to have the image fill up the whole height that is possible and then adjust the width of the view to enable scaling the image without changing the aspect ratio?

I've created a layout with an image view and a web view. The web view is set to have a default visibility of gone. When the activity fires up it displays the image view first and when the web view has finished loading its url, it marks itself as visible and the imageview is marked as hidden.
When the imageview is shown, I would like it to rotate repeatedly just for a little added pizazz.
I have never done animations before in Android and all the posts I found when I asked the internet were not helpful; thus, I have returned to SO for help.
So if I start with this...final ImageView splash = (ImageView)findViewById(R.id.splash);
How do I create a repeated rotate animation and apply it to the ImageView?

When I type ImageView or AnimationDrawable I get a string of errors proclaiming:
AnimationDrawable cannot be resolved to a type.
line 14 Java Problem
I don't understand, do I need to create another class? Or do the AnimationDrawables just not go in the filename.java?
And if I do need to create another class, can you show me how?

I have an XML layout with some custom tabs, a heading, and a ProgressBar(main.xml). I wish to add another XML layout(home.xml) to the main.xml layout, as i wish to keep main.xml re-usable for other activity's layouts and simply add things to it as necessary.The problem: after inflating R.layout.home into rootLayout, it seems as though the ProgressBar contained in rootLayout is hidden underneath the content of home.xml.Is there a way to tell certain views(via XML) to float above other views when the layout is constructed in this way?if not, am i forced to use methods such as progressBar.bringToFront() to raise targeted views to the top?what alternatives do i have in z-ordering views when some layouts are constructed using inflation?
