Funktion zum Umschalten der Sichtbarkeit von tableLayout in Android funktioniert nicht

Question

Ich habe eine Schaltfläche in meinem XML, die, wenn geklickt wird, schaltet die Sichtbarkeit meiner TableLayout. Dies ist der XML,

<LinearLayout 
     xmlns:android="http://schemas.android.com/apk/res/android" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_gravity="center" 
     android:id="@+id/LayoutAddOns" 
     android:orientation="vertical" > 

      <!-- Accordion button --> 
      <Button 
       android:id="@+id/DisplayAddOns"

und dies ist der Java-Code,

public void ShowAddons(){ 

    int TableId = R.id.tableAddOns; 

    TableLayout TableVisibility = (TableLayout)findViewById(TableId); 


    if(TableVisibility.getVisibility() == View.VISIBLE) 
    { 
     TableVisibility.setVisibility(View.GONE); 
    } 

    else 
    { 
     TableVisibility.setVisibility(View.VISIBLE);  
    } 


} 

Es keine Fehler in Eclipse hat, aber als ich führe es aus, es sagt, es ist ein Fehler aufgetreten und erzwingt die Anwendung. Vielen Dank.

Versuch macht ShowAddOns() nehmen View Argument, wie ShowAddOns(View target), auch wenn Sie nicht über die Zielansicht in dem Verfahren verwendet werden.
