我想在显示通知时显示alertdialog（用于暂停通知）我使用系统窗口警报
请帮我写一下这个问题的完美代码
答案 0 :(得分：0)
那么你在调用generateNotification方法的地方，只需使用runOnUiThread，然后在这里显示你的对话框。在您的活动中，将上下文设置为static：static Contaxt context = YourActivity.this;
((Activity) YourActivity.context)
.runOnUiThread(new Runnable() {
@Override
public void run() {
// place your dialog here
}
});
