如何讓我的應用程序每分鐘重複一次該功能？

Question

我現在正在製作一個應用程序，它可以隨機顯示一個數字時鐘onCreate。我想要的應用程序只是每分鐘重複一次該功能。有沒有人有任何想法如何實施？

public class MainActivity extends Activity { 

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

    TextView textView = (TextView) findViewById(R.id.digitalClock1); 
    Random r = new Random(); 

    int x = r.nextInt(350 - 100); 
    int y = r.nextInt(800 - 100); 

    textView.setX(x); 
    textView.setY(y); 
} 


@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    // Inflate the menu; this adds items to the action bar if it is present. 
    getMenuInflater().inflate(R.menu.main, menu); 
    return true; 
} 

}

使用Handler

Handler handler = new Handler(); 
     handler.postDelayed(new Runnable() { 
      @Override 
      public void run() { 
       Random r = new Random(); 

       int x = r.nextInt(350 - 100); 
       int y = r.nextInt(800 - 100); 

       textView.setX(x); 
       textView.setY(y); 
      } 
     }, 1000 * 60);
