Question

我希望活动时间每分钟更新一次，而不仅仅是创建。这是我到目前为止的代码：

public class MainActivity extends ActionBarActivity
{

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

       TimeZone tz = TimeZone.getTimeZone("Atlantic/St_Helena");
        Calendar c = Calendar.getInstance(tz);
        String timez = String.format("Year "+"%02d" , c.get(Calendar.YEAR))

 // Display formattedDate value in TextView

        TextView time = new TextView(this);
        time.setText("Its"+timez+" PM"+"\n\n"+"Ants stretch when they wake up in the morning.");
        time.setGravity(Gravity.TOP);
        time.setTextSize(20);
        setContentView(time);
}}

Answer 1

尝试使用runnable和这样的处理程序：

handler=new Handler();

new Runnable() {
    public void run() {
        c = Calendar.getInstance(tz);
        timez = String.format("Year "+"%02d", c.get(Calendar.YEAR));
        time.setText("Its"+timez+" PM"+"\n\n"+"Ants stretch when they wake up in the morning.");
        time.setGravity(Gravity.TOP);
        time.setTextSize(20);
        setContentView(time);
        handler.postDelayed(this, 60000);
    }
}.run();

Answer 2

这是我到目前为止的代码

new Timer().schedule(new TimerTask() {

        @Override
        public void run() {
            runOnUiThread(new Runnable() {
                public void run() {
                 }
            });
        }
},0,1000);

我想做的是替换，0,1000）;最后有60分钟 - 当前时间。

每分钟更新时间显示，而不仅仅是创建？
