[android-beginners] StringToFloat code
Ok since the EditText.getText. will only allow you to get a string i
made a small program to get the string and convert it to a float. It
was a pain to do. You could change the return to an int or double but
i made this for floats...
Here is the horrible code...
public float StringToFloat(String text)
{
//Used for the for loops
int i = 0;
//The number your go to return
float number = 0;
//Used to specify if your before the decimal or after
int numtodec = 1;
//Size of the int. 123.6 sizeofint = 3
int sizeofint = -1;
//Gets the length of the String
int size = text.length();
//Sets an array of characters equ to the string
char string[] = text.toCharArray();
//Gets the size of the sizeofint and sizeofdec
for(i = 0; i size; ++i)
{
if(string[i] == '.')
{
numtodec = 0;
continue;
}
if(numtodec == 1)
++sizeofint;
}
//resets the num to dec
numtodec = 1;
//Stores the number
for(i = 0; i size; ++i)
{
if(string[i] == '.')
{
numtodec = 0;
continue;
}
int hold = string[i] - 48;
double hold2;
if(numtodec == 1)
hold2 =
java.lang.Math.pow(10.0,(double)(sizeofint - i));
else
hold2 =
java.lang.Math.pow(10.0,(double)(sizeofint+1 - i));
number += hold*hold2;
}
return number;
}

Hi All
I am stuck in a very simple problem.
I have one lengthy string I need to draw that on the device display.
My code is as follows:
void ShowText(String text) {
canv = thread.mSurfaceHolder.lockCanvas();
if (text!= null) {
canv.drawColor(Color.WHITE); //background
color
mPaint.setColor(Color.BLACK); //font color
mPaint.setTextSize(15); //font size
canv.drawText(text, 10, 200, mPaint);
//startign at some
(10,200) coordinates , dratext
}
unlockCanvasAndPost(canv);
}
But the problem here is, the string is going out of the screen. I want
it to break down into multiple lines if it is too big for the screen
width.
Can anybody show me some example to do this?
Thanks
Latha
