DialogHelper控制针异常

刚从bugly中看到反馈的异常：
Attempt to invoke virtual method 'void com.kongzue.dialog.util.DialogHelper.setStyle(int, int)' on a null object reference

但没有更具体的报错信息

Start by locating DialogHelper.setStyle(int, int) and obtain the complete Android stack trace or a reproduction, since the report only identifies a null-object exception. Done means identifying the null reference and documenting or fixing the reproducible failure, with verification of the affected dialog behavior.
