这是我的AndroidManifest.xml：

super.onCreate();
OneSignal.startInit(this)
.setNotificationOpenedHandler(new NotificationOpenedHandler())

}
// This fires when a notificaiton is opened by tapping on it or one is received while the app is runnning.

builder = new AlertDialog.Builder(getApplicationContext())
.setTitle("OneSignal Message")

// Add your app logic around this so the user is not interrupted during gameplay.
if (builder != null)
builder.setCancelable(true)
.setPositiveButton("OK",null)
.create().show();
} catch (Throwable t) {
t.printStackTrace();
}
}
}
}

因为我在申请文件中，所以我不能做活动。这个。 请帮忙。
答案 0 :(得分：0)
我认为this SO answer应该适用于您的情况。特别是以下部分：
您可以使用应用程序上下文通过在调用之前添加来创建对话框 到Dialog.show（）;
Dialog.getWindow().setType(WindowManager.LayoutParams.TYPE_SYSTEM_ALERT);
所以在你的情况下：
Dialog dialog = builder.setCancelable(true).setPositiveButton("OK",null).create();
dialog.getWindow().setType(WindowManager.LayoutParams.TYPE_SYSTEM_ALERT);
dialog.show();
