在規律的時間間隔後調用特定方法

Question

在我的android應用程序中，我想要在特定時間間隔即時調用特定的方法。 「每5秒鐘後」......我該怎麼做......？

Answer 1

您可以使用Timer進行方法的固定期間執行。

下面是代碼的示例：

final long period = 0; 
new Timer().schedule(new TimerTask() { 
    @Override 
    public void run() { 
     // do your task here 
    } 
}, 0, period); 

Answer 2

以上此鏈接被測試和工作正常。這是每秒鐘調用某種方法的代碼。您可以隨時更改1000（= 1秒）（例如3秒= 3000）

public class myActivity extends Activity { 

private Timer myTimer; 

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

    myTimer = new Timer(); 
    myTimer.schedule(new TimerTask() {   
     @Override 
     public void run() { 
      TimerMethod(); 
     } 

    }, 0, 1000); 
} 

private void TimerMethod() 
{ 
    //This method is called directly by the timer 
    //and runs in the same thread as the timer. 

    //We call the method that will work with the UI 
    //through the runOnUiThread method. 
    this.runOnUiThread(Timer_Tick); 
} 


private Runnable Timer_Tick = new Runnable() { 
    public void run() { 

    //This method runs in the same thread as the UI.    

    //Do something to the UI thread here 

    } 
}; 
}
