Android : Specify MaxWidth Of A TextView As Percentage Of Screen Width?
Oct 15, 2009
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?

I think the answer to this question is probably so simple, but I'm struggling....
I have a TableLayout with multiple columns. I want the last column to be of a fixed width, but I want to define that width to just be able to hold the widest possible string from my program. i.e. it is always wide enough to contain "THIS STRING" without wrapping, or wasting any space.
I would like to do this as I have these TableLayouts within a ListView, so it looks very poor when the last column is of variable widths.
I have tried obtaining the string width, even going so far as to put it into a TextView, call getTextSize() then setWidth() on all appropriate TextViews. The problem I hit there is that gettextSize() returns pixels, but setWidth uses ScaledPixels.
I'm sure there is a really simple solution. Can anyone help?

I have a TextView in a RelativeLayout which contains an integer number. The number will range between 1 and 99 - can anyone tell me how to size the TextView so that its width is always the width of the string "99" even if it only contains "1"?
I need this because the positions of the components to the right of this TextView depend on its width, so all are position depending on how many digits the TextView contains.
I don't mind if this is done in XML or code - I just want to avoid having to set the width of a TextView in pixels!

Here is my (non-working) code. It stretches the image horizontally, but not vertically, so it is squashed. Code...

I am writing an android application that has 3 views one below the other. Each view has to be of equal height, depending on the screen size. Each view occupies the full width of the screen. How do you specify in the layout xml that the view has to take up 1/3rd height of the device display height? What would be the appropriate layout to use in this case?

I have a Gallery with a set of images that was downloaded at run time.I followed the example here:http://www.anddev.org/a_androidwidgetgallery_-_example-t332.html but instead of using i.setImageResource(this.myImageIds[position]);I used i.setImageBitmap(bitmaps.get(position));This doesn't fill the entire width of the screen, only as much as the width specified here:i.setLayoutParams(new Gallery.LayoutParams(150, 150)); When I increase this number, the item scales with it instead of showing more images per the example. I've even tried to scale the images before adding them to the set. Not sure what I'm missing, or where other examples of this might be. Any help would be great.

I'm using textview objects to hold labels such as Score, Level etc on my game screen but they don't seem to be displayed where I want them to be. I understand about view hierarchies (parents, children) and am using the gravity tags in the XML layout file but it doesn't seem to have any effect. Could someone just quickly provide a guide to positioning a textview object on the screen, and also linking it in the code so that its contents can be pro grammatically controlled (I believe this would by done via =(TextView) findViewById(r.id.resourcename))? Code...

I've a textview I want to span almost the length of the screen, then 2 buttons at the bottom.
Right now I'm using a relative layout with a textview and two buttons and I can almost get it the way I want but the only thing is the textview isn't as long as I want it. I want it to be as long as necessary for whatever handset is using it. So a constant pixel amount is out.

I have an Android TextView where the view itself is limited to four lines.If the text exceeds this limit I want the end of the view to end with something like.<-- to notify that there is more text here so you can click and open in full screen for example.Not just suddenly stop in the middle of a sentence. Is there a quick fix for this?

I am developing an application in which the layout is independent of screen resolution.
Now my problem is that in TextView the textview layout does change itself when the resolution of screen changes but the size of text remain same.I want that when the resolution is high, according to that the text size should also adjust itself(i.e. text size should be changed).And similarly when resolution is low the text size should also shrink.But here when i reduce Y-AXIS to an extent the text vanishes.I will really appreciate any answer.

CODE:................
This works ok as long as the wordDefinition text isn't very long. But, when I set the text to something very long, it pushes the back button off the bottom of the screen. Why? Isn't the ScrollView supposed to scroll the text in the child TextView?
I've tried playing with weights (e.g., giving the top text view a weight of .2, the scroll view a weight of .7 and the button a weight of .1, but to no avail.
