这是我尝试显示对话框的示例.

AlertDialog.Builder builder = new AlertDialog.Builder(                            activity);                    builder.setMessage(R.string.are_you_sure)                            .setPositivebutton(R.string.yes,                                    dialogClickListener)                            .setNegativebutton(R.string.no, dialogClickListener)                            .show();

注意：在我进行更改之前,此代码已正常工作.我想我应该在新的runnable中运行它,但是如果我必须这样做,谁能告诉我我该怎么做？

解决方法:

我也面临同样的问题.我已经使用标签栏了.只需使用getParent()而不是youractivity.this.

我希望这将有所帮助.
