Android :: SurfaceView Transparent Through Its Parent

Feb 11, 2009

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?

Sep 7, 2010

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.

Android :: BringtoFront The Parent Activity?

Sep 7, 2010

As 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.

Android :: Textview Fill Parent ?

Jul 15, 2010

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?

Android :: Getting A Button Along With Gridview?

Aug 22, 2010

I have a gridview that is inflated by multiple buttons. I used just a gridview and it worked fine. The grid was in correct order and was centered. Although, I wanted to add a button below the grid of buttons that was different and centered. To do this I decided to section off the gridview and then add the button (therefore it wouldn't be affected by the gridview).

I tried the following code to seperate the views:

CODE:...................

The problem is that this code smushes the gridview to the left and oddly it flips it (Position 0 is ont he bottom right and the last button is on the top left pushed off screen). The following image shows what is the result:

Any idea why its pushed to the left and flipped? Or maybe how I could have just the Gridview with the button on the bottom?

Android :: ListSelector On GridView

Aug 24, 2010

I'm trying to use a custom listSelector on a GridView. When I use the default listSelector, I see that it modifies the size of my items so the listSelector display correctly. The list Selector is bigger than my items:

See how when using the default selecto, it make grid items to be resized. Above the gridview I have a LinearLayout with 4 of the same images(ImageView) the GridView contains. http://twitpic.com/2hxkjh

I wanted a custom listSelector, not as bigger as the default (that makes my items smaller), but bigger enough to simulate a border on them without overlap my items content. I'm, not sure if this is an expected behavior, but when I set the listSelector with my own image, I see the selector being fit to my items size. At least my items won't get resized. [url]

Any ideas of how to set a selector that doesn't get resized?

Android :: GridView Row Height

Mar 3, 2010

I have a GridView that displays images, which are, unfortunately, of different sizes. They are shown in between two lines of text:

CODE:.........

If IMAGE1 is the same height as IMAGE2, everything is fine, but if IMAGE1 is longer than IMAGE2, text2.1 will run into text3.1 (padding doesn't seem to help much, as there's too much of it when images are of the same height).

I know there's a way to stretch the images in the ImageView so they are the same height, but is it possible to keep images as is and set the row height somehow?

Android :: Cannot Start Parent Application / Process Is Bad

May 12, 2009

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?

Android :: Scrollable Parent With ListView Child

Dec 14, 2009

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?

Android :: Finish Parent Activity From Child?

Mar 30, 2010

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....

Android :: Activity That Does Not Fill The Parent Screen

Dec 14, 2009

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?

Android :: Parent And Child Activity OnCreate?

Jul 2, 2010

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".
