Question

我正在尝试获取通知内容并自动将其存储到数据库中，一旦从parse.com发布通知，数据应保存在数据库中，无论用户是否单击以查看通知。

这是我到目前为止所尝试的但仍然无效。它仅在用户单击通知时将内容保存到数据库中。

Application.java

public class Application extends android.app.Application{
  public Application() {
  }

  @SuppressWarnings("deprecation")
    public void onCreate() {
    super.onCreate();
      // Initialize the Parse SDK.
    Parse.initialize(this, "YwWVJ1IdukAXQx6WqksoRlA94k1OoJ6cHqdgsInHaTN", "fCh5pWNiSaHaFtuACufgs9va6wq31pte8nuaiCAG6Nb");

    // Specify an Activity to handle all pushes by default.
    PushService.setDefaultPushCallback(this, Notification.class);
  }        
}

FireBackground.java

public class FireBackground extends ParsePushBroadcastReceiver {
    @Override
    public void onPushOpen(Context context, Intent intent) {
        Intent i = new Intent(context, Notification.class);
        i.putExtras(intent.getExtras());
        i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(i);
    }
}

Notification.java

public class Notification extends ListActivity {

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        ParseAnalytics.trackAppOpened(getIntent());
        Intent intent = getIntent();
        Bundle extras = intent.getExtras();
        String message="";

         SQLiteDatabase db;

            db = openOrCreateDatabase(
                "notification.db"
                , SQLiteDatabase.CREATE_IF_NECESSARY
                , null
                );

          //CREATE TABLES AND INSERT MESSAGES INTO THE TABLES
            String CREATE_TABLE_NOTICES = "CREATE TABLE IF NOT EXISTS notices ("
                    + "ID INTEGER primary key AUTOINCREMENT,"
                    + "NOTIFICATIONS TEXT)";
            db.execSQL(CREATE_TABLE_NOTICES);

        if(extras !=null){
            String jsonData = extras.getString("com.parse.Data");
            try{
                JSONObject notification = new JSONObject(jsonData);
                 message = notification.getString("alert");

                    String sql =
                        "INSERT or replace INTO notices (NOTIFICATIONS) "
                        + "VALUES('" + message + "')";       
                    db.execSQL(sql);      

            }
            catch(JSONException e){
                Toast.makeText(getApplicationContext(), "Something went wrong with the notification", Toast.LENGTH_SHORT).show();
            }   
        }      
}

如果有人指示我使用正确的方法，我将不胜感激。感谢

Answer 1

您将通知数据保存到本地数据库的代码在活动中运行。并且在打开通知时启动活动，因此名称为onPushOpen。因此，请使用FireBackground

等方法将保存到数据库的代码移至onPushRecieved(...)

Answer 2

您应该覆盖BroadcastReceiver中的onPushReceive方法，而不是获取必要的数据从意图。这是我的retreiving jsonData的例子：

var path = svg.datum(data).selectAll("path")
  .data(partition.nodes)
.enter().append("path")
  .attr("display", function(d) { return d.depth ? null : "none"; }) // hide inner ring
  .attr("d", arc)
  .attr('id',function(d) {
    return d.name+"-"+d.value;
  })
  .style("stroke", "#fff")
  .style("fill", function(d) { 
      if (d.depth > 0) {
        return color(d.name); 
      }
  }) .each(stash)
  .on("mouseover", mouseover)
//.on("mouseenter",mouseover)
  .on("mouseleave", mouseleave)

然后，您可以使用后台线程实现自己的服务以保存数据。例如，您可以使用IntentService

@Override
protected void onPushReceive(Context context, Intent intent) {
   Bundle extras = intent.getExtras();

   String jsonData = extras.getString("com.parse.Data");
   DBServiceFlow.save(intent);
   } catch (JSONException | ParseException e) {
       Log.e(TAG, "", e);
   }
}

PS：从不在主线程中使用DB。（就像你在通知活动中显示的那样）
