Question

这是我的AndroidManifest.xml：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

            </intent-filter>
        </activity>
    </application>

</manifest>

这是我的申请文件：

public class Tapplication extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        OneSignal.startInit(this)
                .setNotificationOpenedHandler(new NotificationOpenedHandler())
                .init();
    }

    // This fires when a notificaiton is opened by tapping on it or one is received while the app is runnning.
    private class NotificationOpenedHandler implements OneSignal.NotificationOpenedHandler {
        @Override
        public void notificationOpened(String message, JSONObject additionalData, boolean isActive) {
            try {
                String messageTitle;
                AlertDialog.Builder builder = null;

                if (additionalData != null) {
                    if (additionalData.has("discount"))
                        messageTitle = "Discount!";
                    else if (additionalData.has("bonusCredits"))
                        messageTitle = "Bonus Credits!";
                    else
                        messageTitle = "Other Extra Data";

                    builder = new AlertDialog.Builder(getApplicationContext())
                            .setTitle(messageTitle)
                            .setMessage(message + "\n\n" + additionalData.toString());
                }
                else if (isActive) // If a push notification is received when the app is being used it does not display in the notification bar so display in the app.
                    builder = new AlertDialog.Builder(getApplicationContext())
                            .setTitle("OneSignal Message")
                            .setMessage(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();
            }
        }
    }
}

当我点击一下推送通知时，我得到的是LogCat日志：

因为我在申请文件中，所以我不能做活动。这个。请帮忙。

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();

如何在android studio中使用OneSignal？
