I want to determine the available height and width of the parent layout to which I have to add my view.I have used many methods on layout like
layout.getHeight()
layout.getRootView().getHeight()
All these methods return 0(zero) as the result.My main requirement is to be able to give width to a view that is some % of the width of the layout.Also I dont want to use tag for this. I want to do it through code.

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?

How can I get the body (second EditText) to fill the rest of the screen, but still have the scrollview kick in when the contents of the body are too long? Like a height="wrap_content" and minHeight="fill_parent"
layout_height="fill_parent" seems to not do anything if you put them in a scrollview
A working example of what I want is the email app compose window
I tried this and the EditText elements act like they are wrap_content and no filling is happening. Just scrolling if you type enough

View 3 Replies View RelatedI want to put a button next to a EditText and I want their heights to match.For example, from the built in Android browser:
The Go button is the same height as the EditText field.I know I could wrap both these views in a parent layout view, and set both of their heights to fill_parent, and that would make them match.However, I would like to do this without having to give the layout a static size.I would rather have the EditText take whatever height it needs based on the font size and then have the button next to it match whatever height that might be.Is this possible with an xml layout?
I am having problem with a GridView within a RelativeLayout, which is again within a ScrollView. The problem is that the height of the RelativeLayout is not following the height of the contents of the GridView. When there are more than one rows, the GridView is clipped and a scrollbar appears, which is undesirable. I have tried to illustrate my problem using an screenshot from the Android hierarchy viewer. You can see how the red RelativeLayout box has clipped the second row of the GridView. I am pasting the XML layout of the page (page.xml) and the individual grid item (griditem.xml). I have used the following code to inflate the grid items in the gridAdapter code:

I have a SurfaceView that is covering a portion of its parent, a RelativeLayout. I have a background image covering the full RelativeLayout area, and this is my Activity's main layout.
I would like to have the SurfaceView be transparent so that I can see through to the background image on its parent RelativeLayout. I have tried the approach shown in the API Demos example TranslucentGLSurfaceViewActivity, but this succeeds in making the transparency go all the way through my Activity to my desktop!
I'm using the "style/Theme.Translucent" theme on my activity, and setting this on my SurfaceView: mySurfaceView.getHolder().setFormat(PixelFormat.RGBA_8888);
The transparency to the desktop it kinda cool, but not what I'm trying to do! Is it possible to make a SurfaceView transparent only through to its parent?

View 1 Replies View RelatedAs we know, startActivityForResult() used to get a result for a task from parent activity. Here when we click the setResult(). It returns the result to the parent Activity.
Child Activity means it should maintain the persistent state. That is when the users clicks a button on the child activity. It do not finishes that activity and show the Parent Activity. And again i may go to the child activity from parent activity. If the child does not exists it starts a new child activity else it should show the existing child activity with persistent content.
Simply said, my parent Activity starts a new Child Activity. Now both Activities should be alive. How to call the Parent Activity without finishing the child Activity(in other words, How to BringtoFront the parent Activity)? For this scenario,
you can not use startActivity(). Because it creates a new Activity Instance. Not Existing Parent Activity
you can not use startActivityForResult(). Because it finishes the child Activity Instance.

View 2 Replies View RelatedIs there a way to specify layout_height as a percentage of it's parent?
for example, I want an interview LinearLayout view group to only be 70% of it's parent.
I have a simple ExpandalbeList. For the group header view, I'm using a simple TextView, I am setting the background of the text to a drawable. I have the textview parameters set to FILL_PARENT, but the background of the TextView only covers the width of the text. I realize that I can put this all inside of a Linear Layout, but that just seems like a waste. isn't there a way to make the bounds of the text view stretch to the edge of the listview?

As an exercise I attempted to add an AppWidgetProvider-derived class to one of our existing Android applications. When the widget is created and appears on the home screen, the output from adb logcat notes: W/ActivityManager(58): Unable to launch app com.mycompany.myapp/ 10042 for broadcast Intent { action=android.appwidget.action.APPWIDGET_ENABLED comp= {com.mycompany.myapp/com.mycompany.myapp.MyAppWidgetProvider} }: process is bad
This output comes from around line 10814 in ActivityManagerService (looking at cupcake on git). This is running on an ADP 1.5, FWIW. The same AppWidget code, once separated from the main application's project and put into its own simple project, runs as expected, so I know my manifest entries/XML/Java are all as they should be. Has anyone else run into this, or perhaps can the Android team comment on what aspect of my application might be preventing the AM from starting up the process when the widget is added to the home screen?
I know it's considered taboo to place a ListView inside a scrolling container, so is there any "proper" way to accomplish scrolling of a container that has a ListView child in it? An example layout would look something like:
Header
---
"Sub" header
---
ListView with list items
---
Footer
Header and Footer need to remain static on the screen, and the middle content (Subheader and ListView) should scroll between them. I can't have just the ListView scrollable, because the subheader takes up too much space. As it is currently, the Header comes from an <include />, the Subheader contains several views including an Image and some text, and the ListView (actually part of a ViewFlipper) would contain an indeterminate number of items. The Footer has a couple buttons/tabs that are used to control the ViewFlipper (only one of the views in the flipper is a ListView).
The only way I can think of to accomplish this efficiently would be to place the Subheader inside the ListView as the first item -- is there any better way?
My child activity X is called from Parent activity P through startActivity(intent). I want to close P when X called its finish() method. I override a method finishFromChild(Activity child) in P and called finish() in it. But this functions (finishFromChild(Activity child)) is not being called after X finish() Is it a known bug or I am missing some thing? I googled and also searched the groups but no help.
An alternative could be... using StartActivityForResult() and a "fake" onActivityResult, where I can finish the parent activity, but this way is quite bad, i think...
I prefer the first one, if it would work....
Any idea why this doesn't create an activity that looks like a popup instead of an activity that completely fills the screen?
CODE:.............
I assumed that I only needed to set the layout height and layout width to something other than "fill_parent", but it still shows up as a black screen that completely fills the screen.
Ultimately, I simply want to create a popup, but I do not want to use an AlertDialog. Is this possible?
I have a parent activity, and a child activity that extends the parent activity. When the parent starts the child activity,
Which onCreate gets executed first? The child's or parent's?
There is a particular variable I am setting in the Child activity's onCreate method, and right now, it looks like it takes a while to get to the Child activity's onCreate, and so the methods in the Parent are reporting an empty variable. Whereas when I make the Parent sleep for a while, it reports the correct variable.
CODE:............
So, basically, even after the Parent starts the Child, it still returns "Parent Value", but when I have the thread sleep, it return "Child Value".
