我使用了publishDelayed方法来刷新我的Activity,这很好用.但问题是,即使按下后退按钮后延迟方法,也可以回调上一个活动.

//延迟刷新活动后30000毫秒的处理程序

mHandler.postDelayed(new Runnable() {
public void run() {
               dostuff();

        }
            }, 30000);
    }

protected void dostuff() {
Intent intent = getIntent();
finish();startActivity(intent);
Toast.makeText(getApplicationContext(), "refreshed", Toast.LENGTH_LONG).show();
}

public void onBackPressed() {
        super.onBackPressed();
        finish();
        mHandler.removeCallbacks(null);
        }

protected void onStop() {
            mHandler.removeCallbacks(null);
        super.onStop();
    }
