Positioning items on the stage

I am used to work with Flash and if we want to position an item at certain coordinates on the stage we just modify the .x and .y values. But I can't manage to find a way to this to a TextView (or any other item for that matter).
I did manage to get the width and height of the stage using this:
Code:
Display display = getWindowManager().getDefaultDisplay();
stageWidth = display.getWidth();
stageHeight = display.getHeight();
But, if I want for example to position a TextView called tv at the coordinates like this:
tv.x = stageWidth - tv.width - 30
tv.y = stageHeight - tv.height - 30
I don't know how to do it.
Thanks, and sorry if this is a stupid answer...maybe I am to used in working with Flash.

[Q] Item separator in ListView fails! TextSize is the reason?

As you can see in this screenshoot ( ht tp://yfrog.com/myselezione002p ) ListView doesn't show all item separator, seems that the problem is setting textSize for TextView. (I have already tried with ListActivity instead of Activity, but same result)
This is a little testcase:

Thanks for any response!

[Q] Converting an editable text box to be used as a integer

I have a edit able text box that is next to a button lets say onclick of the button it will take the text from the editable text box and converted to an integer so it can be subracted by.. oh lets say 32 so my first method was this.
number = EText.getText();
textOutcome.setText(number - 32);
this gave me an error of
The operator - is undefined for the argument type(s) Editable, int
my second attempt was
textOutcome.setText((Integer.parseInt(EText.getText().toString()) - 32));
This gave me no errors and it ran fine untill i clicked the button which causes the command above to run. and it force closed my application.
Does any one have any ideas i can do, or any sample code?
Thanks,
Blue.

Bumping the topic.

Please can anyone help me with this..!

Have you tried stepping through the code with the debugger? Otherwise, the code you posted looks fine. There is probably something else at play here.

Basicall it force closes whea subtraction is made..

Ahh the debugger found something early in the code thanks for the idea !

You have to do any mathematical arithmetic with the integer type, not with string, So when you extract the number from the EditText you have to convert the string into a integer, or whatever type of number it may be.
WHen you have the integer then you can apply the arithmetic.
when this is done you then have to convert the total into a string type again.
Hope this helps.
So basically im going to write a little of code off the top of my head which obviously can have errors. Since im not testing it.
EditText txbox = (EditText)findViewById(R.id.EditText01);
String txdata = txbox.getText().toString();
int txval = Integer.ParseInt(txdata);
//you should make sure that the value is an integer, if not i think //Integer.ParseInt() will just cut off the rest if its irrational.
//Now you can do arithmetic//
int b = 2;
int t;
t = txval - b;
//The total value is in variable t.
So lets convert this into a string and put it back into an object like edittext or textview
txbox.setText(String.valueOf(t));
//Thats all, hope that helps.

[Q] app crashes whenever call is made to change the content viewthe

whenever I use
Code:
tv.setText("Game Over!"); setContentView(tv);
my program crashes (note: tv is an object of the TextView class)
Before this call is made the program is set to a default view that contains a text view, buttons, etc. But the crash only happens when I call the method to change the view. Any ideas?

You probably wouldnt wanna do setContentView on a textview, unless its the only thing you want on the screen. Are you creating the textview dynamically? (In the java code) Or is this a textview you create in the xml. If you are doing it dynamically, are you giving it LayoutParams first?

Yes its dynamic. What kind of LayoutParams do you mean?

If you just create a new textview...
TextView text = new TextView(context);
its just floating around not attached to anything. Just create a quick layout with a textview in it, and do
setContentView(R.layout.layout2);

or you could try
tv.setLayoutParams(new LayoutParams(LayoutParam.WRAP_CONTENT,LayoutParam.WRAP_CONTENT));

It still crashes, no matter what I do as soon as I try to do anything with the TextView tv, it crashes
setting it works: final TextView tv = (TextView) findViewById(R.id.stats);
But doing ANYTHING with tv crashes.
Examples:
tv.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams. WRAP_CONTENT));
tv.setText("testing");
Anything I'm overlooking?

Well for starters you cant change anything about a variable that you declare as final..

[Q] Reinsert Text to TextView

Hi everyone .
Can I combine to Texts into one TextView ?
I know its very ununderstandable . So let's shape it :
Imagine I have to Buttons That navigates to two different activities which both Have one view , one code but different texts .
Now imagine I have 1hunderd of them .
Can I make just one activity with one TextView item but the texts inside it differs depending on choosing different buttons ? If not understandable again let me know please .
Thanks in advanced

Yeah, you can:
When the button is clicked, do something like this:
Code:
TextView tv = (TextView) findViewById(R.id.[id of the text view]);
tv.setText([either the resource id or the text]);
You can check which text is displayed using the getText() method of the TextView and then display the other text using the method I gave you above. :good:
