Display Values Dynamically In Textview - Android

I have a simple program with one button. Once I clicked on the button loop started and should display the current value in TextView dynamically. But this display the value when loo

Solution 1:

Try this:

inti=0; //declare this globallyfinalHandlerhandler=newHandler();
handler.postDelayed(newRunnable() {
    @Overridepublicvoidrun() {
        if(i != 10) { 
                text.append(" " + i);
                i++;
                handler.postDelayed(this, 1000);
            }
        }
    }, 1000);
}

Make sure you declare int i = 0 globally

Solution 2:

tv.append("text here") is your answer.

Solution 3:

don't use Thread.sleep() in your main UI thread this should give an exception instead use a new Thread like this

ThreadmyThread=newThread(newRunnable() {

        @Overridepublicvoidrun() {
            for (int i=0;i<10;i++){
                          tv.setText("Value of I "+i);
                          Thread.sleep(500);
                         }
        }
    });
myThread.start();

or if there is more complex operations you make you will have to use AsyncTask calss
