I used toasts in my android application. Can I show the toast as long as i wish instead of
Toast.LENGTH_LONG
and
Toast.LENGTH_SHORT
can someone help me with some helpful code segment. Thank you.

What you can do is create a method which with some kind of looping around to make your Toast display as long as duration you want it,
private void showToast(int duration) {
final Toast toast = Toast.makeText(getBaseContext(),
"This is a Toast Message!",
Toast.LENGTH_SHORT);
toast.show();
new CountDownTimer(duration, 500) {
public void onTick(long millisUntilFinished) {
toast.show();
}
public void onFinish() {
toast.cancel();
}
}.start();
}
And then you can call this method as showToast(10000);. So, what it will do is it will keep showing the Toast in loop until the duration and will cancel the toast as the duration is completed.

Try this..
final Toast toast = Toast.makeText(getBaseContext(), "YOUR MESSAGE",Toast.LENGTH_SHORT);
toast.show();
new CountDownTimer(10000, 1000)
{
public void onTick(long millisUntilFinished) {toast.show();}
public void onFinish() {toast.cancel();}
}.start();
Enjoy..

no cannot directly handle that,you have to use handler to cancel the toast like this:
final Toast toast = Toast.makeText(getApplicationContext(), "This message will disappear in half second", Toast.LENGTH_SHORT);
toast.show();
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
@Override
public void run() {
toast.cancel();
}
}, 500); // 500ms is the time to cancel the toast.
