Android PopupWindow驳回问题
我读过很多关于这个常见问题的论坛，但无法在我的应用程序中解决它。 在我的android应用程序中，我需要显示一个弹出窗口，其中有一个具有编辑文本和保存按钮的表单。当用户单击保存按钮时，弹出窗口应刷新。我尝试过解雇方法，但：- Java代码：Android PopupWindow驳回问题,android,Android,我读过很多关于这个常见问题的论坛，但无法在我的应用程序中解决它。 在我的android应用程序中，我需要显示一个弹出窗口，其中有一个具有编辑文本和保存按钮的表单。当用户单击保存按钮时，弹出窗口应刷新。我尝试过解雇方法，但：- Java代码： LayoutInflater inflater = (LayoutInflater) ListActivity.this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

您好，我已经复制了上面的代码，并在我的项目中创建了一个java文件。但它显示了getContext方法的编译错误。它找不到。对我来说很好。根据API级别15编译？如何创建对话框？我正在创建弹出窗口。哎呀。。我有API 10，因为我正在起诉SDK 2.3.3:-这将适用于任何Android版本。它适用于我在安卓2.3及更低版本上的应用。发布一个你如何创建对话框和你得到的堆栈跟踪的片段。
