Is 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 layout xml file named my_layout.xml, in which the root view's layout_width and layout_height has been specified as 200px.
CODE:....
If I used this xml to be included in another xml, and specify the layout_width and layout_height as 100px.
CODE:.....................
What would be the real width/height of my_layout?
I get the following error in logcat: java.lang.RuntimeException: Binary XML file line #26: You must supply a layout_height attribute. Can you please tell me which xml file that I am missing? And it said 'binary xml', does it mean it is actually line 26 in my file? or it is line 26 in the file after it compiles to be a binary xml file?..........

The iPhone version of this software uses the HTML meta-tag:<meta name="viewport" content="width=320, initial-scale=0.95, maximum-scale=2.0, user-scalable=1">..Since Android's WebView doesn't seem to respect that tag I hard-coded the percent using setInitialScale(). However, the WebView is just flat-out ignoring this method call. No matter what number I put in there it shows at 100%.
View 5 Replies View RelatedI 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?
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.

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.
Is it possible for the child of an ExpandableListView also be a parent?
For example, I need something like the following: ParentA ChildA ChildB ParentB ChildC GrandchildA? GrandchildB? ParentC
I'm trying to customize the parent(or header) for an expandablelist and I haven't found a solution yet. I want an imageview and two textviews in the parent. This is driving me insane atm.
View 2 Replies View RelatedI 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?

Motorola Droid user coming from iPhone here. One of the features I miss is having the battery percentage indicated in the status bar next to the little icon (in fact, I'd rather just have the percentage rather than the icon). Is there an app to show that in the status bar? It seems the precision of the battery meter is by 10% increments until it reaches 20%, but even that would be better than just the icon.

I noticed that it is not possible to specify a percentage value for maxWidth.
What is the best way around this?
For example, in the layout xml, is it possible to get a handle on the screen width and apply some kind of arithmetic to it (e.g. maxWidth="(60 * @screenWidth) / 100px")
Also would this approach mean the maxWidth would be automatically recalculated on orientation changes?
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".
