我能够在 onesignal 中成功发送通知。所有功能都运行良好。但是今天当我尝试对通知实现操作按钮时，它不起作用。我尝试添加一个 ID 为“ActionOne”的操作按钮，单击通知下方的此操作按钮，它应该启动一个共享意图来共享我想要的文本。但是每次我这样做时，应用程序都会崩溃。但是，当我尝试将简单的 toast 添加到另一个 ID 为“ActionTwo”的操作按钮时，它起作用了。请帮我解决这个问题。这是代码 -

public class MyNotificationOpenedHandler implements OneSignal.NotificationOpenedHandler {
    @Override
    public void notificationOpened(OSNotificationOpenResult result) {
        OSNotificationAction.ActionType actionType = result.action.type;
        JSONObject data = result.notification.payload.additionalData;
        String open;

    if (data != null) {
        open = data.optString("open", null);

        if (open != null && open.equals("activitytwo")) {
            Log.i("OneSignalExample", "customkey set with value: " + open);
            Intent intent = new Intent(MyApplication.getContext(), Activitytwo.class);
            intent.setFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT | Intent.FLAG_ACTIVITY_NEW_TASK);
            MyApplication.getContext().startActivity(intent);
        } else {
            Intent intent = new Intent(MyApplication.getContext(), MainActivity.class);
            intent.setFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT | Intent.FLAG_ACTIVITY_NEW_TASK);
            MyApplication.getContext().startActivity(intent);
        }

    }

    if (actionType == OSNotificationAction.ActionType.ActionTaken){
        Log.i("OneSignalExample", "Button pressed with id: " + result.action.actionID);


        if (result.action.actionID.equals("ActionOne")) {

            Intent sharingIntent = new Intent(Intent.ACTION_SEND);
            sharingIntent.setType("text/plain");
            String shareBodyText = "hello";
            sharingIntent.putExtra(Intent.EXTRA_SUBJECT,"");
            sharingIntent.putExtra(Intent.EXTRA_TEXT, shareBodyText);
            MyApplication.getContext().startActivity(Intent.createChooser(sharingIntent, "Share via"));

        }else if (result.action.actionID.equals("ActionTwo")) {
            Toast.makeText(MyApplication.getContext(), "ActionTwo Button was pressed", Toast.LENGTH_LONG).show();
        }
      }
   }
}

这是收到通知时的 logcat -

任何一个

通过适配器中的构造函数缓存 Context 对象，或者

从你的角度得到它。

或者作为最后的手段，

在您的意图中添加 - FLAG_ACTIVITY_NEW_TASK 标志：

myIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

编辑 - 我会避免设置标志，因为它会干扰事件和历史堆栈的正常流动。

经过一番努力，我终于找到了解决方案:)

这是共享意图的最终代码 -

Log.i("OneSignalExample", "button id called: " + result.action.actionID);
Intent sharingIntent = new Intent(Intent.ACTION_SEND);
sharingIntent.setType("text/plain");
String shareBodyText = "hello";
sharingIntent.setFlags(FLAG_ACTIVITY_NEW_TASK);
sharingIntent.putExtra(Intent.EXTRA_SUBJECT,"share");
sharingIntent.putExtra(Intent.EXTRA_TEXT, shareBodyText);
Intent share = Intent.createChooser(sharingIntent, "share via");
share.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
MyApplication.getContext().startActivity(share);
