In my code i m trying to find the height the textview occupies..
I used OnGlobalLayout for that ..
here is my code
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
t = new TextView(this);
ViewTreeObserver vto = t.getViewTreeObserver();
vto.addOnGlobalLayoutListener(this);
t.setText("This is to test the text\n Some Text \n
Another ..");
t.append("\nafter something");
Toast.makeText(this, " The value at num =
"+num,Toast.LENGTH_SHORT).show();
setContentView(t);
}
public void onGlobalLayout()
{
num=t.getHeight();
Toast.makeText(this, "Hellooo !! height is "+num,
Toast.LENGTH_SHORT).show();
}
The value of num in onCreate() is always zero but atlast in the
onGlobalLayout() , the correct height is getting stored in num but i
cant use it because it is the end of the application .. Is there any
possibility of getting the text length in the middle of the
application ?
Forgive, if there are any mistakes in the above problem..
Thanks, Siva Kumar
