Toast and Duration

I have a button in my activity. If I click on the Toast show. But when I click Toast show again. Therefore, as a result, when I click many times, this toast will appear for a long time. When it first disappears, the next one appears, etc. How can I do, when I press the button again, the first toast will be hidden.

call the cancel()method to hide Toast if it is already displayed.

Check out this API.

This can simply be called in the Toast object.

Toast toast = new Toast(context);

toast.setText("Text");
toast.show();//(call show()  to display Toast)
toast.cancel();//(call cancel() to  hide Toast).

Add this code to your activity (global toast) and cancel it if you want to show new text.

Toast myLovelyToastThatNeverDies;
public void onClick(View v) {

    if(myLovelyToastThatNeverDies==null)
        myLovelyToastThatNeverDies = new Toast(Activity.this);
    else
        myLovelyToastThatNeverDies.cancel();
    myLovelyToastThatNeverDies.setText("my new text");
    myLovelyToastThatNeverDies.setDuration(anAverageDuration);
    myLovelyToastThatNeverDies.show();
}
