Java 如何在Android运行时动态检索TableLayout中的所有列？

我想在运行时从SQLite动态获取表布局中的14列。我试过了，但得到了算术异常：除以零。我不知道mutateColumnsWidth的表格布局的实际问题在哪里。我将网络浮出水面，但没有找到合适的解决方案。有人能帮我吗。如何解决此问题。提前感谢

这是我的活动代码

SQLiteDatabase sqlDatabase = databaseHelper.getWritableDatabase();
        Cursor c1 =sqlDatabase.rawQuery(performanceQuery , null);

          int rows = c1.getCount();
          Log.e("rows "," = " + rows);

          int cols = c1.getColumnCount();
          Log.e("cols "," = " + cols);

        if (c1 != null && c1.getCount() != 0) 
        {  
            Log.e("11111","11111");
            if (c1.moveToFirst())
            {   
                Log.e("222222","222222");
                // outer for loop
                  for (int i = 0; i < rows; i++) 
                  {
                     TableRow row = new TableRow(this);
                      row.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,
                                 LayoutParams.WRAP_CONTENT));


                    // inner for loop
                       for (int j = 0; j < cols; j++)
                       {
                           TextView tv = new TextView(this);

                            tv.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
                            tv.setBackgroundResource(R.drawable.cell_shape);
                            tv.setGravity(Gravity.CENTER);
                            tv.setTextSize(18);
                          // tv.setTextColor(010101);
                           tv.setPadding(5, 5, 5, 5);

                            tv.setText(c1.getString(j));

                            String strText = tv.getText().toString().trim();
                            System.out.println(" strText " + strText);

                            row.addView(tv);


                       }
                       Log.e("3333333","3333333");
                       c1.moveToNext();

                       Log.e("4444444","4444444");
                       table_layout.addView(row);


                  }
            }
            sqlDatabase.close();
            c1.close();
            Log.e("55555555","55555555");
        }

Here is log error information
