How to Pause/Delay execution in Android Application?

Larry James · 02-18-2012, 07:22 AM

I'm trying to write code that will place a delay between steps without clearing the screen.

Code:

TextView infotext;
String inforstring;

for (int x = 1; x < 10; x++ ){
	infostring = infostring + "\n" + x;				
	infotext.setText(infostring);
	// 10 second delay here
	...
}

I tried using the Thread.sleep() function, but it clears the screen and doesn't give the display back until all the iterations have completed, then all the numbers are displayed.

Code:

try {
	Thread.sleep(10000);
} catch (InterruptedException e) {}

Thanks in advance for any suggestions or comments.

I left a line out of my previous post (for the benefit of anyone that might want to test the example. I'm reposting the code below.

I'm also including a for-next loop to set a delay. This presents the same problem as in my original post.

Code:

TextView infotext;
String infostring = "Counting:";

for (int x = 1; x < 10; x++ ){
	infostring = infostring + "\n" + x;
        //line left off previous post
	infotext = (TextView) findViewById(R.id.infotext);
	infotext.setText(infostring);

	// Delay loop between iterations
        // Do nothing loop... just count to a big number
	for (int y = 1; y < 10000000; y++){}
}

Thanks again for any comments on this!
