Question

我尝试使用Intent将推送数据从接收器传递到活动，但它似乎无法正常工作。知道为什么吗？这是我的实施：

的AndroidManifest.xml

unsigned int num=0;
double percentage=0.00;

 for(register unsigned int row=0;row<data_labels.label.size();row++)
 {
     if((data_labels.label[row]=correct_data_labels.label[row]))
     {
         num=num+1;
     }
 }

 percentage = (num/data_labels.label.size());

PushData.java

package com.appName;

import android.content.Context;
import android.content.Intent;
import android.nfc.Tag;
import android.util.Log;

import com.parse.ParseAnalytics;
import com.parse.ParsePushBroadcastReceiver;

import org.json.JSONException;
import org.json.JSONObject;


public class ParseReceiver extends ParsePushBroadcastReceiver {
    private final String TAG = "Push_Notify";

    @Override
    public void onPushOpen(Context context, Intent intent) {
    Log.i(TAG, "onPushOpen triggered!");

    ParseAnalytics.trackAppOpenedInBackground(intent);
    Intent mainIntent = new Intent(context, MainActivity.class);
    mainIntent.putExtras(intent.getExtras());
    mainIntent.putExtra("method", "updateStatus");

    mainIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);


    JSONObject pushData;

    String alert;
    try {
        pushData = new JSONObject(intent.getStringExtra(ParseSupplyReceiver.KEY_PUSH_DATA));
        alert = pushData.getString("alert");
        String name = pushData.getString("name");
        String contactNumber = pushData.getString("contactNumber");
        String durationText = pushData.getString("duration");

        mainIntent.putExtra("alert", alert);
        mainIntent.putExtra("pushData", new PushData(name, contactNumber, durationText));

    } catch (JSONException e) {
        Log.i(TAG,"JSONException: " + e.getLocalizedMessage());
    }

    context.startActivity(mainIntent);

   }
}

在MainActivity中实现onNewIntent：

package com.appName;


import android.os.Parcel;
import android.os.Parcelable;


public class PushData implements Parcelable{
   String name;
   String contactNumber;
   String durationText;


   public PushData (String name,String contactNumber,String durationText ){
  /*
   * Reconstruct from the Parcel. Keep same order as in writeToParcel()
   */

       this.name = name;
       this.contactNumber = contactNumber;
       this.durationText = durationText;
  }

  public PushData(Parcel source) {
      name = source.readString();
      contactNumber = source.readString();
      durationText = source.readString();

  }


    @Override
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeString(name);
        dest.writeString(contactNumber);
        dest.writeString(durationText);
   }

   @Override
   public int describeContents() {
      return 0;
   }

   public static final Parcelable.Creator CREATOR = new Parcelable.Creator() {

      public PushData createFromParcel(Parcel source) {

          return new PushData(source);
      }

      public PushData[] newArray(int size) {

          return new PushData[size];
      }

  };
}

我可以知道这里有什么问题吗？我在另一个应用程序上做了类似的实现，它完全正常。

Answer 1

将FLAG_ACTIVITY_SINGLE_TOP标记添加到您的意图中（见onNewIntent(Intent intent)）。

Answer 2

我认为它是s not about your FLAG,but your activity的launchmode;

似乎只有当它的launchmode是singleTask或sigleTop时才会调用此方法;

Answer 3

你的Manifest中也有拼写错误。变化

<activity android:name="com.appNamw.RouteView"
    android:label="@string/title_activity_route_view"
    android:screenOrientation="landscape">

要

<activity android:name="com.appName.RouteView"
    android:label="@string/title_activity_route_view"
    android:screenOrientation="landscape">

onNewIntent没有被调用
