Android :: Setup TextView To New String?

TextView control to my app. by default, its set to something like @+id/TextView01. How do I Set the text attribute of the TextView control to my newly created String resource?

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 :: 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 :: Convert TextView To String (kind Of) Droid?

Oct 13, 2010

I have an object on my main.xml layout file called thefact that is TextView. I also have a string called sharefact. I want to save what text is in the TextView into the sharefact string. I can't do:

sharefact = thefact

Or anything similar to that because it would want me to convert sharefact into a textview.

Android :: Change Textview Text From String Array In Widget Without Global Variables

Nov 21, 2010

I am trying to make an android widget like the Google Voice Widget where users can go through an array of Strings which is retreived from the SQLite database. The problem is using global variables in the widget provider. I need to hold the index of the value they are currently on in order to pass it to the intents which are created when the left or right buttons are created. The variable is always returned as zero though.

Android :: Hello World Button Display Random Number

Apr 16, 2010

Brand new to droid programming, but would love to learn as much as possible, so I finally got my emulator working correctly, I even got a hello world button to work. I'm attempting to make this button display a random number, I've googled this and came up with this code:

Random generator = new Random();
int n = generator.nextInt(n);

I fixed the Random function by including some Random java utility. I'm assuming this code above goes in the .java file of the project, so my button code looks as follows (tested and works):

PopUpText.makeText(v.getContext(), "Hello World",
PopUpText.LENGTH_LONG).show();

I figured I could replace "Hello World" with n to display the number in the box, however the following error is stopping the compile:
The local variable n may not have been initialized

Android :: Layout With ScrollView And TextView

Apr 1, 2010

I want to have a textview (like a console or output window), which scrolls. I saw on this list that the TextView will not scroll on its own unless I wrap it in a ScrollView. So I did that and it worked. The problem is, it seemed no matter what I did I could not get the TextView to be higher than one line. This was only when it was embedded in the ScrollView, and didn't seem to change whatever I set the TexView's layout_height to.

Here is my layout:

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 :: Add TextView/Layout To Map's Overlay / OverlayItem?

Apr 12, 2010

When a marker is clicked on google map, a small square area is displayed with hyperlinks. I guess OverlayItem does not render hyperlinks for its snippet. How to achieve this? Ideally I want to assign a layout with all sorts widgets. Presume I can display a small floating activity window when the marker is clicked, but is this the standard way doing this? The drawback of floating activity window is that if want to click another marker, user has to dismiss the current window first.
