我试图做到这一点

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.main);

    t=new TextView(this); 

    t=(TextView)findViewById(R.id.TextView01); 
    t.setText("Step One: blast egg");

    try {
        Thread.sleep(10000);
    } catch (InterruptedException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    t.setText("Step Two: fry egg");

但由于某些原因，只有第二个文本显示，当我运行它。我想可能有一些做与视频下载（）办法阻止。因此，有人可以告诉我如何实现一个计时器异步？

but for some reason, only the second text shows up when I run it. I think it might have something to do with the Thread.sleep() method blocking. So can someone show me how to implement a timer "asynchronously"?

感谢。

推荐答案

我刚刚发布了Android，谷歌讨论组的这个答案

I just posted this answer in the android-discuss google group

如果您只是想添加文本视图，以便显示步骤一：爆蛋第二步：炒鸡蛋那可以考虑使用 t.appendText（第二步：煎鸡蛋 ）; 而不是 t.setText（第二步：炒鸡蛋）;

If you are just trying to add text to the view so that it displays "Step One: blast egg Step Two: fry egg" Then consider using t.appendText("Step Two: fry egg"); instead of t.setText("Step Two: fry egg");

如果你想彻底改变什么是在的TextView ，以便它说：第一步：爆蛋的启动，然后它说：第二步：煎鸡蛋在时间后，你可以随时使用

If you want to completely change what is in the TextView so that it says "Step One: blast egg" on startup and then it says "Step Two: fry egg" at a time later you can always use a
