1.用handler进行操作

private Handler handler = new Handler(){
        @Override
        public void handleMessage(Message msg) {
            super.handleMessage(msg);
            if (count < 0 ) {// 跳转
                startActivity(new Intent(MainActivity.this,
                        Activity_two.class));
                finish();
            } else {// 倒计时处理
                text.setText(count + "s");
                count--;
                handler.sendEmptyMessageDelayed(99, 1000);
            }
        }
    };

2.onCreate里面的内容

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        handler.sendEmptyMessageDelayed(99,1000);

    }
