I have a main screen, and I would like to dynamically spawn a view under it with a button click, then slide the main view off the screen revealing the view below it. I've accomplished this, but I feel like there's got to be a better way. The way I've done it is very limited in that you can't just spawn views over and over again under the main. My main XML file looks like this:..............

I want to have a View pop in at the bottom of the page exactly like the software keyboard view does in the compose section of the Mms app.It slides in from the bottom, as if it's being added to a vertically oriented LinearLayout, only making the ListView smaller.It becomes a part of the current layout instead of popping up over the top of it.I'd like to to this exact thing with my own custom View.

View 2 Replies View RelatedI want to dynamically pull in a layout from an external source. As discussed in this thread from September 2009 -
http://groups.google.com/group/android-developers/browse_thread/threa.
I am wondering if the situation has changed since this discussion or if it is likely to change. I understand the need to use pre-compiled xml layouts so if there is an option to dynamically pull in a layout that is already compiled that would be fine. Basically I want a setup where I can change a view layout without an app update. The elements within the view would be fairly static (e.g. there will be 2 buttons call foo and bar that fire fooOnClick and barOnClick). The only work around I can think of is a custom scripting language that allows the definition of views that are created from code. Ideally this would parse the same xml as a standard layout. Obviously this would involve a lot of code and probably be fairly slow.
Button btnFoo = new Button(); btnFoo.setText("foo"); dynamicLayout.addView(btnFoo);
If this is the only option at least the EdsMagicLayoutInflater class would be reusable across projects.
I've a list view with custom list adapter(list_item.xml). I have multiple layout folder to support multiple screen size. I found out when I inflate using LayoutInflater, its always taking the view from main "layout" folder.
I've a phone with screen size "427x320".

I want the layout inflater to pick the list_item.xml from "layout-427x320" folder and not "layout" folder.
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
View 4 Replies View RelatedI would like to have a button in my android application trigger a slide down view of a form.

View 2 Replies View RelatedI am trying to set up a ViewFlipper that changes a SlidingDrawers content each time a button is pressed. So far every view I set up worked fine, but now I am trying to create a ListView (including single_choice_mode) within a child view of the ViewFlipper, but my attempt only let to a NullPointerException. As I only discovered ViewFlipper today, I am not yet familiar with it and may not have understood it completely. if someone could give me a hand and help me find out what I have done wrong, that would be great. Here is what I have done:
The code for the onClick event of the ImageButtons:
public void onClick(View v){
if (v == btnExposure){
mFlipper.setDisplayedChild(0); }
else if (v == btnProperties){
mFlipper.setDisplayedChild(1);}
else if (v == btnSpecialEffects){
mFlipper.setDisplayedChild(2);.............
I have 2 tables, Table-A and Table-B. The Table-B is below Table-A and I am using RelativeLayout.
I set the animation for the Table-A to slide up as follows.
TranslateAnimation slide = new TranslateAnimation(0, 0, 0, -(Table-A Height));
slide.setDuration(500);
slide.setFillAfter(true);
slide.setFillEnabled(true);
slide.setAnimationListener(new Animation.AnimationListener() {
[Code]...
The Table-A slides perfectly, but Table-B does not move until the Table-A animation is over and Table-B jumps to the top once the animation is completed. This does not look good as user sees Table-B jumping to the top.
Removing setAnimationListener and adding Table-A.setVisibility(View.GONE); at the bottom will also produce the same result.
Am I doing something wrong?
I 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?

So my layout looks basically like this:
<ScrollView>
<RelativeLayout>
<BunchOfViews/>
<ImageView android:layout_alignParentBottom="true"/>
</RelativeLayout>
</ScrollView>
I have the ScrollView so all of the layout always is visible no matter the height of the screen. The problem is that on a very high screen, I still want my imageview to be at the bottom. However, a child of a ScrollView dont seem to have a defined bottom. The View is placed at the top of the layout. How can I solve this problem in a neat way?
I like to know how can i clone a view object which is already there in the view hierarchy, so that it can be added to the same view hierarchy again.
View 1 Replies View RelatedI 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?
View 2 Replies View RelatedI have a WebView inside the ScrollView. The content of WebView dyanamically changes when it displays different html page. I have the following issue: For example I have A.html, and B.html. The content of B.html is larger than A.html, so the page is longer. When WebView load B.html, the ScrollView stretches its size to enable itself scroll for B.html, then if I go back to A.html, ScrollView doesn't resize itself. (The scroll area is exceed the content of A.html) What I want to have, is dynamic change the scroll area of scroll view to fit the webview's content.

View 1 Replies View RelatedI have a problem statement, and here it is: My requirement is: There are a number of images shown on the screen. I want to allow the user to drag and drop any of the images to anyother image. Based on which image is dragged and on which is it dropped, I need to do something specific. So, I need to find a way so that I can get my source view and my target view.To understand this in a better way, consider a practical scenario. In the File Explorer of Windows, we can drag and drop items from the left pane showing the directory tree to any of the folders shown in the right pane.If anyone of you ever faced a similar scenario, please let me know because I could not find a direct support to such a thing (Drag and Drop) in the platform, so may be I need to find an innovative solution to it.

View 1 Replies View RelatedI'd like to show a png or jpg I downloaded from the next in an image viewer intent, but can't get it to work.
Bitmap bmp = getImageBitmap(jpg);
String path = getFilesDir().getAbsolutePath() + "/test.png";

FileOutputStream fos = new FileOutputStream(file);
bmp.compress( CompressFormat.PNG, 100, fos );
fos.close();
Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(new File(path)), "image/png");
startActivity(intent);
I know the bitmap is downloaded ok (use the same routine for supplying it my ImageView instances elsewhere in my app) - I think it wrote to file ok, I can see it on disk and the file size is correct. The intent is launched but an exception is thrown: then the new activity just sits there, blank. How does this work?
