处理程序或计时器 android [英] handler or timer android

问题描述

我正在尝试每 1 分钟显示一条消息！！不停！我发现在固定延迟后仅显示一次味精的示例！你能帮忙怎么设置吗??或者如果使用计时器更好，它是如何工作的，我需要一个例子！！

i'm tryin' to display a msg every 1 min!! non stop! i found exemple that display the msg just one time after a fixed delay!! can you help how can set it?? or if using timer is better how it works i need an exemple!!

public class TimertestActivity extends Activity {
    /** Called when the activity is first created. */

      @Override   
      public void onCreate(Bundle icicle) {   
        super.onCreate(icicle);   
        setContentView(R.layout.main);  
        Handler handler = new Handler();
        handler.postDelayed(
            new Runnable() {
                public void run() {
                    afficher();
                }
            }, 1000L);

      }   

      public void afficher()
      {
          Toast.makeText(getBaseContext(),
                     "test",
                     Toast.LENGTH_SHORT).show();
      }
}

谢谢！

推荐答案

试试这个代码 -

public class TimertestActivity extends Activity {
    Handler handler = new Handler();
    Runnable runnable = new Runnable() {
        public void run() {
            afficher();
        }
    };

    /** Called when the activity is first created. */

      @Override   
      public void onCreate(Bundle icicle) {   
        super.onCreate(icicle);   
        setContentView(R.layout.main);  
        runnable.run();
      }   

      public void afficher()
      {
          Toast.makeText(getBaseContext(),
                     "test",
                     Toast.LENGTH_SHORT).show();
          handler.postDelayed(runnable, 1000);
      }
}
