待处理意图的多个实例-移动开发问题

Multiple Instances of Pending Intent(待处理意图的多个实例)

本文介绍了待处理意图的多个实例的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我创建了一个小部件，单击该小部件会激活 PendingIntent.问题是当屏幕上有多个小部件时，只有最新的小部件会启动 PendingIntent.

I created a widget that when clicked activates a PendingIntent. The problem is when I have more than one widget on the screen only the latest one will start the PendingIntent.

我已经阅读了一些关于唯一请求代码的信息，但没有弄清楚这一点.

I have read some about a unique request code, but not figured this out.

有什么想法可以让我拥有多个小部件并且 PendingIntents 可以为每个小部件工作吗?

Any ideas how I can have multiple widgets and the PendingIntents work for each?

这是我的代码片段:

Intent openApp = new Intent(context, RunningTally.class);
    openApp.putExtra("widgetId", appWidgetId);
    PendingIntent pendingAppIntent = 
        PendingIntent.getActivity(context, 0, openApp, PendingIntent.FLAG_CANCEL_CURRENT  );
    views.setOnClickPendingIntent(R.id.openFull, pendingAppIntent);

推荐答案

恰好在发布我的问题后，我想出了一个答案.我将 appWidgetId 作为唯一"请求代码传入，瞧！这是现在的片段:

So happens that after posting my question, I came up with an answer. I pass in my appWidgetId as the "unique" request code and voila! Here is the snippet now:

Intent openApp = new Intent(context, RunningTally.class);
    openApp.putExtra("widgetId", appWidgetId);
    PendingIntent pendingAppIntent = 
        PendingIntent.getActivity(context, appWidgetId, openApp, 
                                  PendingIntent.FLAG_CANCEL_CURRENT);
    views.setOnClickPendingIntent(R.id.openFull, pendingAppIntent);
