Android :: Fix TextView Width By String?

Oct 18, 2010

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?

Android :: Set A Minimum Width - In Characters - For A TextView?

Jul 6, 2010

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!

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?

Android :: TextView Automatically Truncate Last 3 Char Of String

Nov 3, 2009

If a String is longer than the TextView's width it automatically wraps onto the next line. I can avoid this by using android:singleLine (deprecated) or by setting android:inputType="text". What I now need is something that replaces the last 3 characters of my String with "...". Since I'm not using a monospace font this will always be different depending on the letters used in my String. So I'm wondering what's the best way to get the last 3 characters of a String in a TextView and replace them. Maybe there's already something implemented in the Android framework, since this must me a common problem.

Android :: Avoiding String Allocation In TextView.setText()

Dec 28, 2009

On Android 1.5, using the Allocation Tracker I see that every time I call TextView.setText() with a StringBuilder as first argument, a String gets allocated from the following call stack (first line is last call):

java.lang.AbstractStringBuilder toString java.lang.StringBuilder toString android.text.TextUtils stringOrSpannedString android.widget.TextView setText

I tried specifying the buffer type with setText(strBuilder, TextView.BufferType.NORMAL) but it doesn't change anything.

Is there a way to avoid this allocation?

Android :: Android - Updating TextView String Through AIDL Service

Aug 12, 2010

I have an app that uses a TabHost. Several of the Tabs share a common HUD. I am using a service to periodically update those values by calling an AIDL function when ready.

However, since several of the Tabs are using the same HUD I would like to abstract that part out.

I thought about having the HUD.xml use a String resource as it's value and then the abstracted class can update the String resource. However, apparently Android can not update String resources programatically.

The only alternative solution I see would be using SharedPreference.

I have concerns accessing a Database everytime the value is refreshed.

Android :: Java Datetime Values From String To Long To String

Oct 1, 2010

In Android, capturing date from datepicker and storing as string in sqlite. Sorting by date doesn't work because they're strings (unless I'm doing it wrong.I've googled this issue for ~5 days, and it looks like there should be a way to capture the date from the date picker, convert it to a Long, store it in sqlite as a Long, select and sort on the Long date value, then convert the Long back to a "mm/dd/yyyy" string for display. I've tried various combinations of parse statements, Date, FormatDate, etc. with no luck at all.On activity start, get today's date and display it in button which calls the datepicker.Capture new date from datepicker (if one is entered), save it as a long to sqlite.On opening an activity showing a listview of records, select from sqlite with orderby on date (Long), convert Long to "mm/dd/yyyy" string for display in ListView.

Android :: Gallery Item Width Vs Gallery Width

Jan 10, 2010

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.
