当警报对话框打开且手机(模拟器)更改其方向时,应用程序崩溃

Question

伙计们我一整天都在搜索和研究这个问题.该应用程序不仅在对话框打开时崩溃,而且在旋转器打开时崩溃(我确信这将是一堆我没有遇到过的其他情况).

在onRetainNonConfigurationInstance()和onConfigurationChanged(配置newConfig)之间进行选择对我没有帮助.(也许我错了) - 实际上我更喜欢使用第一个.

但我想问:对于一个打开的对话框或打开的微调器,我是否必须从头开始创建所有内容？这是一种方式吗？有时,用户可能会改变方向,重新初始化一个包含大量小部件的大班级是没有价值的.

请给我提示和指导.提前致谢.

我知道这是来自调用dismiss()函数.但是如何在打开对话框时处理方向更改？

Answer 1

您是否正在使用progressDialog.show(),并progressbarDialog.dismiss()在AyncTask？

如果是,请尝试在AyncTask中使用showDialog(id)and dismissDialog(id)而不是它.您必须在onCreateDialog()显示加载对话框中编写自定义对话框.showDialog和dismissDialog方法是活动级方法.我的意思是它们是在Activity或其Context上调用的.因此,即使在方向更改后重新创建活动,也会为Dialog提供最新的上下文.

在这里查看示例代码.DIALOG_PROGRESS根据您的要求修改案例.

此外, onRetainNonConfigurationInstance()与方向变化完美配合.只是由于窗户泄漏问题,你无法看到它.
