Android中如何动态的调整Dialog的背景深暗
在Android开发中,Dialog和DialogFragment可通过设置`Window`的`backgroundDimAmount`来控制背景变暗,突出对话框。在DialogFragment的`onCreateDialog`或`onViewCreated`中,获取`Dialog`的`Window`,设置`LayoutParams.dimAmount`(例如0.5f)并添加`FLAG_DIM_BEHIND`标志。要动态调整,可保存`LayoutParams`并在需要时更新。对于Dialog,创建时直接设置同样属性。还可以通过定义主题样式设置背景模糊程度。
