用线程控制dialog的呈现时间，思路非常easy，直接show代码了，我也是为了方便自己记录

private void showProgressDialog() {

	pDialog = new ProgressDialog(mContext);

	pDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);

	pDialog.setProgress(100);

	pDialog.setMessage("请稍等一秒...");

	pDialog.setIndeterminate(false);

	pDialog.show();

	WindowManager.LayoutParams lp = pDialog.getWindow().getAttributes();

	lp.gravity = Gravity.CENTER;

	Window win = pDialog.getWindow();

	win.setAttributes(lp);

	// 仅仅呈现1s

	new Thread(new Runnable() {

		@Override

		public void run() {

			long startTime = System.currentTimeMillis();

			int progress = 0;

			while (System.currentTimeMillis() - startTime < 1000) {

				try {

					progress += 10;

					pDialog.setProgress(progress);

					Thread.sleep(100);

				} catch (InterruptedException e) {

					pDialog.dismiss();

				}

			}

			pDialog.dismiss();

		}

	}).start();

}
