java - Activity 泄漏了窗口 com.android.internal.policy.impl.PhoneWindow$DecorView

Question

我在此 AddRestaurantActivity 上遇到此错误

这是我的 AddRestaurantActivity.java 文件。这是更新数据库并创建一个带有 goggle geo place 纬度和经度的新餐厅的 Activity 代码。在模拟器中，当我按“创建”按钮创建餐厅时，应用程序死掉了(不幸的是，餐厅查找器已停止)。并且在下面发现了logcat中的错误

Answer 1

您在调用 onPostExecute 之前调用 finish()。我认为这会泄露你的pDialog。尝试在关闭 pDialog

后在 onPostExecute 中移动 finish()
