您可以使用Handler

你需要导入import android.os.Handler;

    public void onPageStarted(WebView view, String url, Bitmap favicon) {
        super.onPageStarted(view, url, favicon);
            final ProgressDialog progressDialog = new ProgressDialog(ActivityTalentHunt.this);
            progressDialog.setMessage("Page is loading...");
            progressDialog.show();

            new Handler().postDelayed(new Runnable() {
                @Override
                public void run() {
                    progressDialog.dismiss();
                }
            },2000);

        }
    });
