我有类似问题的经验。如果您正在创建上下文变量，请随时随地使用它。即使是为了祝酒，也不要编写getApplicationContext（）。并在oncreate（）{}内更改上下文变量，如下所示
将上下文声明为类级变量我有过类似问题的经验。如果您正在创建上下文变量，请随时随地使用它。即使是为了祝酒，也不要编写getApplicationContext（）。并在oncreate（）{}内更改上下文变量，如下所示
将上下文声明为类级变量按singleChoiceButton后，您不会取消对话框。调用
dialog.cancel（）onClickstartActivity（）onClickstartActivity（）dialog.cancel（）Toast.makeText(getApplicationContext(), items[item], Toast.LENGTH_SHORT).show();
只需注释或删除此语句…在代码中做2处更改
Toast.makeText(getApplicationContext(), items[item], Toast.LENGTH_SHORT).show();
