Android and toast during

Question

I have toast in method showText(); This method shows toast when we call that method. In second Activity I have a button and when I click on the button my Toast must be shows. Everything work great but when I click two or mnore times my toast will be showing long time. I want to toast show only when I click on button and when I click again, first toast disapear and shows again.

public void showText(String msg) {

        Toast.makeText(this, msg, 1000).show();

}

How I can do this?

Answer 1

you can do it this way

class YourActivity extends Activity implements OnclickListener
{

Toast toast = null;

void onclick(View v)
{
//call showText() method
}

// modify your showText as follows
public void showText(String msg) {

  if(toast != null)
   {
    toast.cancel();
    toast = null;
   }
   toast = new Toast(YourActivity.this);
   toast.setText(msg);
   toast.show()

}


}

Answer 2

Instead of calling show(), you can keep a reference to the Toast you just created

Toast toast = Toast.makeText(this, msg, 1000);
then toast.show();
and then later, call some methods on the toast like toast.cancel();
