Android :: Get Height Of A Linearlayout

Nov 1, 2010

I'd like to get the height of a linearlayout. I found more information in this answer

View.getWidth()/View.getHeight() won't give you a meaningful answer until the view has been measured.

How will I know that view has been measured? Is there some event for it?

Solution for me is to get layout's height in overriden onWindowFocusChanged()

Android :: Proportional Width Of Elements In LinearLayout

Jun 2, 2010

I have a horizontal LinearLayout and in it I have EditText and Spinner elements. Which attributes I need to adjust so I would get proportional widths: I want EditText to take 3/5 and Spinner - 2/5 of all available width?

My code looks like this:

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

I tried setting android:layout_weight, but somehow it does not look "stable" enough for me - when EditText has no text - everything looks fine, but as soon as I start entering text into it - it starts expanding and Spinner shrinking accordingly...

Android :: Dynamically Set EditText Height?

Nov 23, 2010

I want to simply set the height of an EditText component to be 50% of the user's screen height.

I'm creating the initial layout from an xml file (main.xml), loaded in the Activity's onCreate(Bundle). From the xml configuration, I understand how to set the EditText height to a literal value, e.g., android:layout_height="150dip", and from the onCreate(Bundle), I understand that I can call setHeight(int) on the EditText component, but the call to setHeight(int) appears to be ignored, and if I don't have the layout_height setting out of the xml, then I get an exception when my app is starting, complaining that the height value is required (and the app dies).

Is there a way to set the height from the xml based on the user's screen height? In other words, within the xml, is it possible to retrieve the user's screen height and use it to calculate a value for a component?

(I'm placing the EditText in a LinearLayout with vertical orientation.)

Android :: Control Frame Height And Width Of Captured Video : SetVideoSize() Does Not Work

Aug 5, 2010

On a Nexus One (for example), the camera application is able to capture H.264 video at 720x480 (the "High" quality setting). However, when using the MediaRecorder API, it always seems to capture at a fixed frame size of 320x240.

I would expect the setVideoSize() method to control the frame size (as in the prepare fragment below), but it appears to have no effect (using Froyo 2.2 Android SDK).code...

Discussions on the android developers list seem to indicate this is a long standing issue. Can anyone advise how the frame size can be controlled, or if it is possible at all with the current API?
