使用 MpAndroidChart api 饼图 api 时出现 java.lang.IllegalArgumentException : DrawerLayout must be measured with MeasureSpec. EXACTLY.error

Question

嗨，我正在尝试在饼图顶部实现一个抽屉导航，但它不断崩溃，但它似乎打开了其他 Activity ，非常感谢。我使用 apptheme 作为主题，使用 MpAndroidChart api 作为饼图

Java 代码:

    Cursor res= db.ViewData();


    PieChart expensesPieChart = (PieChart)findViewById(R.id.chart);

    ArrayList<Entry> entries = new ArrayList<>();

    if(res.getCount() > 0)
    {
        int count = 0;
        res.moveToFirst();
        do
        {
            entries.add(new Entry((float)res.getDouble(2), count));
            expensesCategories.add(res.getString(1));
            count++;
        } while(res.moveToNext());
    }

    PieDataSet expensesDataSet = new PieDataSet(entries, null);
