更新的TextView每一秒 [英] Update TextView Every Second

问题描述

香港专业教育学院环顾四周，似乎没有从什么香港专业教育学院试过到目前为止...

Ive looked around and nothing seems to be working from what ive tried so far...

    @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.deskclock);

    TextView tvTime = (TextView) findViewById(R.id.tvTime);
    TextView tvDate = (TextView) findViewById(R.id.tvDate);

    java.util.Date noteTS = Calendar.getInstance().getTime();

    String time = "hh:mm"; // 12:00
    tvTime.setText(DateFormat.format(time, noteTS));

    String date = "dd MMMMM yyyy"; // 01 January 2013
    tvDate.setText(DateFormat.format(date, noteTS));

我基本上希望的setText方法来更新或刷新每秒左右，所以我时钟实际工作像它应该做这样的处理程序..香港专业教育学院看到的方法和运行并没有什么工作，所以任何帮助，这将是巨大的感谢。 ：）

I basically want the setText methods to update or refresh every second or so, so my clock actually works like it should do.. Ive seen methods like handlers and run and nothing worked so any help with this would be great thanks. :)

推荐答案

添加以下code在你的onCreate（）方法：

Add following code in your onCreate() method:

Thread t = new Thread() {

  @Override
  public void run() {
    try {
      while (!isInterrupted()) {
        Thread.sleep(1000);
        runOnUiThread(new Runnable() {
          @Override
          public void run() {
            // update TextView here!
          }
        });
      }
    } catch (InterruptedException e) {
    }
  }
};

t.start();

这code开头，睡1000毫秒每一轮的主题。

This code starts an thread which sleeps 1000 milliseconds every round.
