How Make Progress Bar For 15 Sec Loading?

codes progressBar = (ProgressBar) findViewById(R.id.progressBar); textView = (TextView) findViewById(R.id.secdelay); // Start long running operation in a b

Solution 1:

You can set the max of the progress bar to 15secs*5 = 75 to enable updating smaller 'bites' for a smoother animation.

Then update progress by 1 each 200ms.

progressBar.setMax(75)
while (progressStatus < 75) {
    progressStatus += 1;
    // Update the progress bar and display the//current value in the text view
    handler.post(new Runnable() {
        publicvoidrun() {
            progressBar.setProgress(progressStatus);
            textView.setText(progressStatus+"/"+progressBar.getMax());
        }
    });
    try {
        // Sleep for 200 milliseconds.//Just to display the progress slowly
        Thread.sleep(200);
    } catch (InterruptedException e) {
        e.printStackTrace();
    }
}

Could also sleep only 100ms using a max of 150.
