TableLayout removeAllViews 자식을 제거하지 않음

새로 고침 메서드에서 새 단추 배열을위한 공간을 만들기 위해 TableRow 요소를 지우고 새로 업데이트 된 TableRows의 공간을 만들기 위해 TableLayout을 지우려고하지만 TableLayout isn 지워졌어. 그것은 나타납니다 table.remveAllViews(); 작동하지 않습니다.TableLayout removeAllViews 자식을 제거하지 않음

어떤 코드 행이 com.example.tilegame.MainActivity.refresh (MainActivity.java:167)입니까 – Mike

@Mike refresh() 메소드에서 'table.addView (row, x);'입니다. –

당신이하고있는 한 OnCreate

for(int x = 0; x < 3; x++) 
    { 
     TableRow row = new TableRow(this); 
     for(int y = 0; y < 3; y++) 
     { 
      row.addView(buttons[count]); 
      count++; 
     } 
     table.addView(row, x); 
    }

하지만 당신의 새로 고침 코드가있다 : 당신이 경우에 로컬 행 객체를 생성하지 않기 때문에, 당신은 새로 고침 테이블에 변수를 여러 번 수업 행을 추가하려는

for(int x = 0; x < 3; x++) 
    { 
     for(int y = 0; y < 3; y++) 
     { 
      row.addView(buttons[count]); 
      count++; 
     } 
     table.addView(row, x); 
    }

. TableRow 행을 제거하는 것이 가장 좋습니다. 당신이 당신의 메소드 변수와 같은 명명 규칙을 사용하고 있고 내가 볼 수있는 곳이면 row 범위의 클래스를 사용하고 있지 않기 때문에 클래스에서 가져온 것입니다.
